Small intestinal loop cancer treatment methods. Initial signs, symptoms and diagnostic algorithm for small intestine cancer

Colon cancer refers to cancers that form in the large and small intestine. It occurs in both men and women. Signs of intestinal cancer are quite minor at the initial stage.

A malignant tumor forms on the mucous surfaces of the intestine, and most often the tumor appears in the large intestine; there are cases when it is found in the sigmoid, rectum, colon or cecum. The survival prognosis of patients with any cancer depends on the stage at which it was detected. The sooner a tumor can be detected, the greater the patient’s chances for complete healing.

Why intestinal cancer develops, what are the first signs of the disease and what methods of prevention exist - we will look further in the article.

About bowel cancer

Colon cancer is a malignant transformation of the epithelium that can affect any segment of the intestine.

The most susceptible to this disease are people in the age group after 45 years, men and women to the same extent, every 10 years the incidence rate increases by 10%. Colon cancer varies in its histological structure; in 96% of cases it develops from glandular cells of the mucous membrane (adenocarcinoma).

Depending on the location of the tumor, there are:

Small intestine cancer. It occurs quite rarely, in approximately 1-1.5% of cases of all cancers of the digestive tract. The disease mainly affects elderly and senile people; the disease affects men more often than women. Of all parts of the small intestine, tumors prefer to be localized in the duodenum, less often in the jejunum and ileum.
Colon cancer. The predominant number of tumors in this area are located in the sigmoid and rectum. Among people who prefer meat, pathology is observed more often than among vegetarians.

It takes about 5-10 years for colon cancer to develop from a polyp, such as in the colon. An intestinal tumor grows from a small polyp, the symptoms of which in the first stages are characterized by sluggish symptoms.

It can manifest itself, for example, as a gastrointestinal disorder, which distracts from the primary cancer, since many do not pay attention to the discomfort in the intestines during the disorder, not knowing what kind of pain can arise from intestinal cancer, which is why they treat diarrhea.

Causes

Causes of colon cancer:

Elderly age. Here, how old a person is plays an important role. According to statistics, intestinal diseases affect people aged 50 years and older.
Intestinal diseases. People suffering from inflammatory bowel pathologies are most susceptible to this disease.
Wrong lifestyle. If you visit a medical forum, these factors include poor nutrition, including a large percentage of consumption of fats and animal products, smoking, and drinking strong drinks.
Hereditary factor. A person is at increased risk when his relatives have had various forms of intestinal diseases.

In men, according to statistics, this is the second most common cancer after lung cancer, and in women it is the third. The risk of developing cancer increases with age. In medicine there is such a definition of intestinal cancer - colorectal cancer.

First signs

With this diagnosis, cancer cells form and grow in the body, their presence causes the appearance of a malignant tumor. It is almost impossible to determine their presence at an early stage, since the first symptoms and signs of intestinal cancer in women and men are similar to classic indigestion and digestive problems.

In order not to miss the onset of the disease, you should pay more attention to the following signs:

a feeling of heaviness in the stomach not associated with eating;
poor appetite, sudden weight loss;
aversion to fried fatty foods;
signs of dyspepsia;
diarrhea followed by prolonged constipation;
signs ;
blood during bowel movements and in stool.

The main problem with cancer is absence of specific symptoms in the early stages, so patients consult a doctor at stages 3-4, when treatment options for colon cancer are already limited.

Stages of development

There are five distinct stages in the development of colon cancer. The complete absence or weak severity of manifestations is observed up to the second (in rare cases even to the third) stage. In the third and fourth stages, the patient experiences severe pain, forcing him to seek medical help.

Stages of development of bowel cancer:

Stage 0 is characterized by the presence of a small accumulation of atypical cells, characterized by the ability to rapidly divide and capable of degenerating into cancer. The pathological process is limited to the mucous membranes.
Stage 1 – the cancerous tumor begins to grow quite rapidly; it does not extend beyond the intestinal walls until metastases can form. Symptoms may include disorders of the digestive tract, to which the patient does not pay due attention. At this stage, when examining the patient using colonoscopy, the appearance of neoplasia can already be detected.
At stage 2, the tumor grows to 2-5 cm and begins to penetrate the intestinal walls.
Stage 3 is characterized by increased activity of cancer cells. The tumor quickly increases in size and penetrates the intestinal wall. Cancer cells invade the lymph nodes. Neighboring organs and tissues are also affected: regional lesions appear in them.
At stage 4, the tumor reaches its maximum size, gives metastases to distant organs. Toxic damage to the body occurs due to waste products of the malignant neoplasm. As a result, the operation of all systems is disrupted.

Life expectancy is determined by the size of the tumor and its ability to localize. Tumor cells that have spread to the surface layer of the epithelium allow 85% of patients to survive. When the muscle layer is affected, the situation worsens - the survival rate does not exceed 67%.

In accordance with the International Classification, there are:

Adenocarcinoma;
Colloid cancer;
Signet ring cell;
Squamous;
Undifferentiated and unclassifiable forms.

Most often (about 80% of cases) adenocarcinoma is diagnosed - glandular cancer, originating from the epithelium of the intestinal mucosa. Such tumors are highly, moderately and poorly differentiated, which determines the prognosis. Signet ring cell carcinoma often affects young people, while squamous cell carcinoma is more often localized in the rectum.

Symptoms of bowel cancer: manifestation in adults

Signs of bowel cancer appear late in the course of the disease. Symptoms of intestinal cancer in the early stages are sluggish, almost unnoticeable. But you should also pay attention to them in order to eliminate irreversible consequences.

Symptoms of intestinal cancer depending on the type:

With stenotic oncology, constipation and colic appear due to the narrowed lumen. At the same time, in the first stage of cancer, a person suffers from flatulence with relief after defecation.
Signs of enterocolitis type bowel cancer are constantly changing stools from diarrhea to constipation and vice versa.
The dyspeptic form is characterized by constant belching with heartburn and the appearance of bitterness in the mouth.
Pseudo-inflammatory oncology causes nausea with vomiting, chills, fever and unbearable pain.
Symptoms of cystitis type intestinal cancer are the appearance of blood when urinating with pain.

Other symptoms:

Quite often, when a malignant tumor develops in the intestines, patients experience fullness, even after a successful trip to the toilet;
some experience sudden, unexplained weight loss, despite maintaining their usual routine and diet;
the presence of blood impurities in the stool may also indicate the development of an oncological process in the intestines;
the first signs of intestinal oncology are usually mild, so they can be mistaken for general malaise (drowsiness, general weakness, fatigue) or digestive disorders. However, as the process worsens, they become more pronounced and complemented.

Signs of intestinal cancer are determined by the location of the tumor and the stage of its development. If the tumor has affected the right part of the organ, the following symptoms occur:

diarrhea;
the presence of blood in the stool;
pain in the abdominal area;
anemia.

Development of a tumor in the left part of the intestine:

The patient complains of constant constipation, difficulties during excretion of feces, and bloating.
There is a frequent alternation of loose stools with constipation, through narrowing and relaxation of the lumen of the colon, this is often a symptom of cancer.
Excretion of feces occurs with great difficulty, often with blood and mucus, and is accompanied by painful sensations.

Symptoms and manifestation
thick	Signs of colon cancer in men and women: Constipation, diarrhea; Digestive problems - bloating, rumbling; The presence of blood in the stool; Abdominal pain; Loss of body weight; False urges or tenesmus; For complications such as: fistulas, inflammation, abscesses a number of other symptoms are added.
thin	Specific symptoms of small intestine cancer: recurrent abdominal pain accompanied by a “copper taste”; vomiting and nausea; weight loss; anemia; liver dysfunction.
sigmoid colon	Predominant characteristic symptoms may be as follows: the appearance of impurities of blood, pus, mucus in the stool; false urge to defecate; intoxication of the body; flatulence; acute pain during bowel movements.

Symptoms of bowel cancer in women and men

Signs of intestinal cancer in men and women with this course are practically no different. Later, if the tumor progresses and spreads to neighboring organs, the prostate is the first to be affected in men, and the vagina is the first to be affected in women; the rectal space and anal canal are also affected.

At the same time, the patient begins to worry severe pain in the anus, coccyx, sacrum, lumbar region, men feel difficulty during urination.

If it is oncology, the clinical outcome is not always favorable. Malignant neoplasm appears in women after 35 years of age; in the primary form, it does not spread metastases to the uterus. First, the patient experiences general weakness throughout the body and classic signs of dyspepsia, then specific signs of an intestinal tumor appear. This:

recurrent pain during bowel movements;
disruption of the menstrual cycle;
blood in stool;
impaired urination;
sudden weight loss, lack of appetite;
blood impurities in the daily urine sample;
aversion to fried, fatty foods.

Late stages of colon cancer are characterized by the addition of general symptoms to local ones. Signs of intestinal cancer appear:

The skin becomes dry and pale.
Frequent dizziness and headaches.
Weakness and fatigue of the patient.
Unreasonable weight loss and exhaustion.
Damage to other systems and organs of the body.
Low presence of blood in the body, low level of protein in it.

The appearance of metastases

Colon cancer most often metastasizes to the liver; there are frequent cases of damage to the lymph nodes of the retroperitoneal space, the peritoneum itself, abdominal organs, ovaries, lungs, adrenal glands, pancreas, pelvic organs and bladder.

The following circumstances become unfavorable factors for the prognosis:

tumor growing into fatty tissue;
cancer cells with a low degree of differentiation;
large intestine with perforation;
the transition of primary cancer to organs and tissues “in the neighborhood” and to large veins, closing their lumen;
carcinoembryonic antigen of high concentration in plasma before surgery. It is associated with an increased risk of recurrence regardless of cancer stage.

Patients with metastases are divided into two groups:

patients with single metastases;
patients with multiple metastases (more than 3).

Diagnostics

The diagnostic search begins with a detailed clarification of the nature of the complaints and clarification of the presence of patients with colonorectal cancer among close relatives. Particular attention is paid to patients with previous inflammatory bowel processes and polyps.

In the early stages, the presence of intestinal cancer can be indicated by any even mild sensation of discomfort in the abdominal area, which is complemented by changes in the blood test and the patient’s age over 50 years.

Features of the blood test:

decreased hemoglobin levels and red blood cell counts;
level up ;
high ESR;
presence of blood (occult blood) in the stool;
increased blood clotting;
tumor markers.

The diagnosis is made after the following studies:

X-ray diagnostics of the intestines (irrigoscopy). It is an X-ray examination of the intestinal walls after the administration of an X-ray contrast agent through an enema, for which a barium suspension is used.
Retromanoscopy. The examination of a section of the intestine from the anus to a depth of 30 cm is carried out with a special device that allows the doctor to see the intestinal wall.
Colonoscopy. Examination of the intestinal area from the anus to a depth of 100 cm.
Laboratory examination of feces for occult blood.
CT and MRI can determine the location of the tumor, as well as the presence or absence of metastases.

How are people with bowel cancer treated?

To get rid of cancer, different methods are used: surgery, radiotherapy and chemotherapy. Treatment of rectal cancer, like any other malignant tumor, is a very difficult and lengthy process. The best results are obtained by surgery, during which the tumor and surrounding tissue are removed.

If the disease is diagnosed in a timely manner, surgical intervention is performed with a retromanoscope, which is inserted into the rectum through the anus. At the last stage of the disease, extensive surgical entry is used. Sometimes patients with intestinal oncology have this organ partially cut off.

After surgery, the two parts of the intestine are sewn together. If it is impossible to connect them, one of the parts of the intestine is removed to the peritoneum.

Treatment also includes:

Radiation therapy uses x-rays to stop tumor growth and cause cancer cells to die.
Radiotherapy is a preparatory stage for surgical treatment. It is also indicated in the postoperative period.
Chemotherapy involves the administration of cytostatic drugs that have a detrimental effect on tumors. Unfortunately, these drugs also negatively affect healthy cells in the body, so chemotherapy has a lot of unpleasant side effects: hair loss, uncontrollable nausea and vomiting.

Chemotherapy is used systemically, before or after surgery. In some cases, local administration into the blood vessels feeding metastases is indicated. The main drug used for chemotherapy is 5-fluorouracil. In addition to it, other cytostatics are used - capecitabine, oxaliplastin, irinotecan and others. To enhance their action, immunocorrectors (interferogens, stimulators of humoral and cellular immunity) are prescribed.

Forecast

The prognosis for colon cancer depends on the stage at which the disease was detected. Thus, with the initial forms of the tumor, patients live long, and the five-year survival rate reaches 90%, while in the presence of metastases it remains no more than 50%. The most unfavorable prognosis is in advanced cases, as well as with significant damage to the rectum, especially in the distal section.

How long do people live at different stages of bowel cancer?

The initial stage (difficult to diagnose) is a guarantee that a positive result will reach 90-95% survival rate, if, of course, the surgical intervention was successful.
At the second stage progression of the tumor and its spread to neighboring organs leaves a chance of survival for 75% of patients. That is, those patients who have successfully undergone surgery and radiation therapy.
At the third stage, the size of the tumor is critical, and it grows into regional lymph nodes. 50% of patients manage to survive.
The fourth stage practically does not guarantee a successful outcome. Only 5% manage to survive a malignant neoplasm that has grown into individual organs and bone tissues, forming extensive metastases.

Prevention

Oncological diseases are insidious and unpredictable. People who have a hereditary predisposition to cancer or have been diagnosed with diseases that can transform into cancer, as well as all people over the age of 40, should think about prevention.

Increased physical activity;
Enriching the diet with foods containing fiber;
Quitting bad habits (smoking, drinking alcohol).

Colon cancer is a dangerous disease that can be prevented by following preventive measures and conducting a full diagnosis of the body 1-2 times a year. If you or your loved ones have the symptoms described in this article, be sure to make an appointment with a gastroenterologist and get diagnosed.

Oncology or cancer of the small intestine is characterized by the appearance of low-quality tumor lesions of certain areas of the small intestine (jejunum, ileum or duodenum). The main manifestations of the disease are dyspeptic disorders (flatulence, nausea, spasmodic abdominal pain, vomiting, etc.).

A late visit to the doctor threatens sudden weight loss due to gastric disorders, as well as intestinal stasis and, as a result, intestinal bleeding.

Statistics on the location of the cancer process of tumor development in the small intestine are as follows:

Health to you and your loved ones! Do not give up

duodenal oncology accounts for approximately 48% of cases;
Oncology of the jejunum was detected in 30% of the disease;
Oncology of the ileum accounts for 20% of cases.

Most often, small intestinal cancer occurs in older men aged approximately 60 years and older. As a rule, men are more likely than women to develop this disease, especially in Central Asian countries.

Reasons for the development of the disease

A large number of cases of small intestinal cancer occur in the presence of obvious chronic diseases of the gastrointestinal tract, as well as against the background of inflammatory and enzymatic processes localized in the small intestine.

The following gastrointestinal diseases may be predisposing factors:

duodenitis;
peptic ulcer;
Crohn's disease;
enteritis;
diverticulitis;
colitis;
celiac disease;
genetic abnormalities;
benign intestinal processes;
malignant tumor processes of other organs that metastasize throughout the body.

The predominant high percentage of damage to the initial section of the small intestine is determined by the irritating effect of bile and food blastimogens supplied with food from outside, as well as gastric juice on the above section of the small intestine.

It was revealed that cases of diffuse polyposis of varying pathology can be considered a contributing factor to the formation of small intestinal cancer.

There is a high probability of the prevalence of small intestinal cancer in chronic smokers, people with alcohol and drug addictions, as well as in people exposed to radioactive components.

Fans of canned foods, well-fried foods, and foods with a predominance of animal fats also fall into the category of people with an increased risk of small intestinal cancer.

Classification

According to histology, low-quality neoplasms of the small intestine are represented by the following types:

By histological type

Adenocarcinoma– is a cancer that develops from the glandular tissue of the body. A rare form of small intestinal cancer that develops within the major duodenal papilla. This tumor is usually ulcerated and has a fleecy surface.

Carcinoid– in structure it resembles the epithelial form of small intestinal cancer, which occurs most often, because it is localized in any part of the intestine. The most common location is in the appendix (vermiform appendix), less often in the ileum and even less often in the rectum.

Lymphoma– a relatively rare type of tumor formation in the small intestine. According to statistics, lymphoma forms only in 18% of cases of small intestinal cancer. In this group of tumor processes, lymphosarcoma and lymphogranulomatosis or Hodgkin's disease are distinguished.

Leiomyosarcoma– a fairly large tumor, more than 5 centimeters in diameter. This type of tumor-like formation is easily palpable through the abdominal wall and is the main cause of intestinal obstruction, followed by perforation of the intestinal wall and bleeding.

Types of Tumor Growth

Depending on the characteristic development of the existing tumor, small intestinal cancer is divided into two types: exophytic and endophytic.

Exophytic nature the tumor grows into the intestinal lumen, thereby causing stasis of a certain part of the small intestine, and subsequently flowing into intestinal obstruction. In addition, an exophytic tumor is a formation with clearly defined structured boundaries, having an external resemblance to polyps, fungi or plaques. If such a tumor ulcerates, it becomes saucer-like in the central part.

The most dangerous and malignant is the endophytic (infiltrative) tumor.

This type of tumor growth is characterized by the tumor extending into other organs without any visible boundaries. The tumor seems to spread along the walls, flowing over the membranes of the organs and penetrating into other areas of the body through the lymphatic vessels and plexuses.

This type of tumor does not grow into the lumen of the organ and does not have certain defined boundaries. The endophytic type of tumor growth is accompanied by perforation of the small intestine and subsequent bleeding.

The worldwide systematization of the statistics of tumor formations in the small intestine according to the TNM classification looks like this:

Tis – pre-invasive oncology;
T1 – growth of cancer in the submucosal layer of the intestinal wall;
T2 – tumor growth in the muscle tissue layer of the small intestine;
T3 – penetration of the tumor into the subserous layer of the walls of the small intestine or the area located behind the peritoneum for a length of no more than 2 centimeters;
T4 – ingrowth of the formation into parts of the peritoneum, as well as other parts of the intestine more than 2 cm long, organs surrounding the intestine;
M0 and N0 – the tumor develops without metastasis;
N1 – metastasis to surrounding lymph nodes (mesentery, gastric area, pancreaticoduodenal region and liver);
detection of cancer carriers in the omentum, kidneys, peritoneum, adrenal glands, liver, lungs and bone tissue.

Diagnostics

The system of diagnostic procedures for the manifestation of cancer of the small intestine has its own characteristics and uniqueness.

In order to identify and recognize a tumor of the duodenum, it is necessary to perform a gastroduodenoscopy procedure, as well as fluoroscopy using a contrast agent. Diagnosis of oncology of the ileum involves the use of irrigoscopy and colonoscopy.

Video: Colonoscopy of the intestine

The main role in identifying obstacles in the form of narrowing in the passage of the small intestine, as well as stenosis and dilatation of the intestines, is played by radiography using a barium passage.

Often, a specific diagnostic approach can begin with the use of a selective angiography procedure of the intestinal cavity.

Each of the endoscopic methods used to diagnose the disease provides the opportunity to take the necessary biopsy to obtain the morphological composition of the tumor and a clear diagnosis and, as a result, appropriate cancer treatment. Based on the biopsy result, it is possible to determine the type of tumor growth, type and degree of malignancy of the formation.

To diagnose and detect metastasis, ultrasound examination (ultrasound) is performed:

pancreas;
liver;
adrenal glands;
kidney

The following series of studies are also being conducted:

multislice CT of the abdominal cavity;
bone tissue scintigraphy;
chest x-ray;
diagnostic laparoscopy;

It is necessary to clearly contrast small intestinal oncology with the following diseases:

inflammatory but benign processes in the small intestine;
scrofuloderma of the small intestine;
enteritis (Crohn's disease);
tumors localized in the retroperitoneal regions;
sudden obstruction of mesenteric vessels;
disturbance in the correct physiological position of the kidneys;
tumors of the ovaries and uterus in women;
congenital stasis of the small intestine;
colon oncology.

The colonoscopy method can detect the initial stages of tumor growth in the intestines or subtle changes in the internal structure of the intestinal wall. And with the help of chromoscopy, you can examine the inner lining of the small intestine and diagnose neoplasms with their subsequent removal.

Treatment of small intestine cancer

Depending on whether surgical intervention is possible at a given stage of small intestinal cancer, it is highly effective to perform an extensive ectomy of the entire cancerous area of the small intestine together with the surrounding mesentery and lymph nodes.

It is possible to radically remove the tumor, including healthy tissue, because the length of the small intestine is sufficient for such an extensive operation to remove tissue.

In addition, the removed area is restored artificially as a result of the imposition of enteroenteroanastamosis (surgical joint between intestinal loops) or enterocoloanastomosis (connection between loops of the large and small intestines).

In the case of duodenal cancer, therapy consists of duodenectomy with additional distal gastricectomy and pancreaticectomy.

If the stage of small intestine cancer is advanced and extensive resection is unacceptable, then surgical implantation of a bypass anastomosis is performed in a healthy area of the small intestine.

In addition to surgery, chemotherapy is also used. By the way, often with inoperable stages of cancer, the only way to alleviate the patient’s suffering is the use of chemotherapy. This treatment helps slow down the growth of the tumor.

According to statistics, 2/3 of cases of small intestinal oncology require surgical intervention. A radical method of treatment helps reduce symptoms and increases life expectancy. Often an ectomy is just a way to alleviate the patient's suffering.

Forecast

The prognosis generally depends on timely contact with an oncologist and the stage of developing cancer. Early diagnosis of the tumor and its removal can give the patient a chance of complete recovery from cancer. It is much easier to perform an ectomy on an uncomplicated tumor than to perform operations on severe stages of cancer.

It is important to undergo annual preventive examinations regarding the presence of neoplasms in the body, especially after 40 years. According to statistics, small intestinal cancer is one of the most curable types of intestinal cancer. Due to the fact that the small intestine is poorly supplied with blood, therefore, metastasis develops very slowly and infected blood enters the body in negligible quantities.

Therefore, the prognosis for patients with small intestinal cancer is in many cases very good.

This is one of the few forms of cancer that, if treated promptly, promotes full recovery.

Many patients, after intestinal cancer is cured, continue to live a full life and only remember their illness at annual examinations.

Prevention

Provided early surgical intervention, the development of the pathological process of small intestinal cancer is stopped and the effect of the operation is consolidated by chemotherapy.

A number of simple rules to help prevent the occurrence of small intestinal cancer:

maintaining an active lifestyle, despite age;
consumption of vegetable coarse fiber more than animal fats;
conducting regular preventive examinations;
If you suspect a disease, immediately contact a specialist.

Take care of your health, conduct a full examination of your body on time.

Small intestinal cancer is a malignant neoplasm that has specific symptoms and manifestations. This lesion affects the duodenum and ileum. Usually the disorder is accompanied by dyspeptic disorders. The patient often experiences rapid weight loss. Symptoms and manifestations of small intestinal cancer are individual and directly depend on the degree of neglect of the pathology. The first possible signs of deviation must not be ignored. It is important that the sick person undergoes a comprehensive medical examination and confirms or denies the presence of the disease.

If cancer is detected as early as possible, cure is possible

In this article you will learn:

Factors provoking the disease

Colon cancer has an incompletely established etiology. The true reasons for the deviation have not been clarified. Doctors only highlight a number of possible factors provoking the deviation. In most cases, the disease develops against the background of existing pathologies of the gastrointestinal tract.

Pathology is also formed under the influence of the current inflammatory process. The main triggers for colon cancer are described in the table.

Gastrointestinal diseases	The following pathologies of the gastrointestinal tract increase the risk of developing small intestinal disease: duodenitis, colitis, enteritis, stomach ulcers, Crohn's disease, the presence of benign neoplasms in the gastrointestinal tract. Cancer can also be caused by a malignant neoplasm that is present in other internal organs.
Hereditary predisposition	The risk of cancer localized in the intestines increases in people whose relatives have experienced this disease.
Bad habits	Smoking, as well as alcohol and drug addiction, have a detrimental effect on the functioning of the entire body. The small intestine is no exception. Over time, people with bad habits run the risk of cancer.
Abnormal stool	Pathological changes in stool in the form of diarrhea or constipation have a detrimental effect on the functioning of the gastrointestinal tract and overall well-being. This is usually the result of an unhealthy diet, which is dominated by foods high in fat, smoked foods, flour, confectionery and fried foods. Along with some food, harmful chemical additives enter the body, which are extremely undesirable. Constant straining contributes to injury to the intestinal tract. Loose stools, on the contrary, irritate the intestinal mucosa. Frequent constipation or diarrhea is a direct path to cancer.

Treatment of the disease has almost nothing to do with the underlying causes of cancer. All that needs to be done is to eliminate the provoking factor. Therapy is selected based on the stage and form of the current deviation.

People with a hereditary predisposition to developing small intestinal cancer should undergo comprehensive testing regularly. This will allow timely detection of a malignant disease.
Stages and forms

To classify a malignant lesion, pay attention to the following signs:

the nature of the formation of cancer cells;

cellular structure of a malignant neoplasm.

Forms of cancer can be different
Based on the type of growth of the malignant formation, exophytic and endophytic cancer are distinguished. The first of these tumors grows into the internal part. In appearance, such a neoplasm resembles a mushroom. Plaques and polyps have limited borders. Their surface is lumpy. The pathology is usually accompanied by prolonged constipation.

Endophytic cancer is characterized by intestinal damage that does not have clear boundaries. It looks like a spreading neoplasm. All layers of the intestine are affected.

Pathology is also distinguished by cellular structure. Doctors distinguish the following types of cancer:

adenocarcinoma;

carcinoid;

lymphoma;

leiomyosarcoma.

Cancer occurs in 4 stages. At the first stage, the size of the tumor in the intestine does not exceed 2 cm in diameter. As a rule, there are no symptoms at this time. Metastases do not spread.

Cancer varies in types and stages
Stage 2 of the cancer process in the intestine is characterized by a slight increase in the tumor. The first symptoms appear. The formation grows into nearby tissues. Metastases do not spread.

Stage 3 is characterized by the rapid growth of a malignant neoplasm in the intestine. Metastases spread to the lymph nodes. Symptoms of cancer are pronounced.

It is characterized by active tumor growth into neighboring tissues and organs. The patient's condition deteriorates greatly. The prognosis is the least favorable. The patient usually faces death.

Main symptoms

In the first stage of cancer, there are usually no symptoms. The patient is unaware of the course of the pathological process. The disease is discovered during a medical examination regarding other problems.

One of the symptoms to watch out for is nausea and vomiting.
The main symptoms include nausea and gag reflex. In addition, the patient complains of periodic cramping sensations in the abdomen and heaviness. These are the first signs of cancer to appear.

The clinical picture of cancer localized in the small intestine is very similar to many signs of gastrointestinal diseases. Only a doctor can establish an accurate diagnosis using complex diagnostics.

Associated symptoms

Usually the clinical picture is the same in men and women. However, sometimes in patients cancer is accompanied by:

disruption of the menstrual cycle;

paleness of the skin;

discomfort when urinating.

Women may experience menstrual irregularities
Women in advanced stages of cancer located in the intestines develop through defects through which fecal matter and mucous secretions penetrate. Later they exit through the vagina.

Associated symptoms of cancer include:

intestinal obstruction;

blood in feces;

formation of ulcers and fistulas;

disruption of the functioning of some internal organs;

pain during bowel movements;

rapid loss of body weight;

signs of intoxication of the body;

skin rashes.

The patient complains of a feeling of unfinished bowel movement.

Symptoms of metastasis

Colon cancer can metastasize to the liver, lungs, peritoneum and adrenal glands. In this case, the patient is faced with additional symptoms:

Small intestinal cancer affects its sections, which include the duodenum, ileum, and jejunum. The disease is diagnosed quite rarely, in 1% of cases of the total number of gastrointestinal cancers. Mostly male patients aged 60 years or more are predisposed to it.

At the initial stage, the disease occurs without severe symptoms. In this regard, many patients seek medical help already in the most advanced stage. First of all, this threatens metastasis and, as a consequence, secondary oncology.

Causes of the disease and its varieties

Among the reasons for the development of oncology are:

chronic diseases of the gastrointestinal tract;
benign intestinal neoplasms and inflammation;
malignant tumors located in other organs;
Peutz-Jeghers syndrome and genetic abnormalities;
nicotine addiction and alcoholism;
frequent consumption of “heavy” foods;
consequences of radioactive radiation.

Experts believe that not the least important reason is a hereditary predisposition to cancer.

There are several types of intestinal tumors. Among these are adenocarcinoma (the tumor is covered with ulcers and has a fleecy surface), carcinoid (mainly localized in the appendix or ileum), leiomyosarcoma (one of the largest tumors, determined by palpation even through the peritoneal walls), lymphoma (the rarest tumor that combines signs of lymphosarcoma and diseases of lymphoid tissue).

Symptoms and stages

At the beginning of the disease, there are no obvious signs of small intestinal cancer. Phenomena such as nausea, periodic cramps and heaviness in the abdomen, heartburn, flatulence and stool disorders, irritability and general weakness rarely cause severe concern.

The manifestation of symptoms of oncology becomes obvious already at stages 3 or 4. Common symptoms of small intestine cancer include:

intestinal obstruction;
bleeding and damage to the intestinal walls;
formation of ulcers and fistulas;
disturbances in the functioning of the liver and pancreas;
pain during bowel movements;
general intoxication and accelerated weight loss;
lack of iron in the body.

Mostly, small intestine cancer occurs in the same way in both sexes. Additional signs of intestinal cancer in women include pale skin, menstrual irregularities and discomfort during urination.

Typical stages of disease development:

Stage 0

The onset of oncology is indicated by a few accumulations of atypical cells, their active degeneration and division. The onset of the disease at this stage can only be determined by examining the composition of the blood.

Stage 1

Characteristic is the location of the tumor within the small intestine and the absence of metastases.

Stage 2

The tumor can penetrate beyond the boundaries of the intestine and affect other organs. Metastases are not detected at this stage of the disease.

Stage 3

Metastases are found in nearby lymph nodes and organs. There is no distant metastasis yet.

Stage 4

Metastases penetrate through the lymphatic system to distant organs. Oncology can be found in the bones, adrenal glands, bladder, liver, pancreas, lungs, etc.

In rare cases, during the development of the disease, discomfort during swallowing food, a feeling of the presence of a foreign body in the abdominal cavity, and a false urge to defecate are noted. In each specific case, the symptoms of small intestine cancer are not the same and are determined by the influence of various factors.

Diagnosis and treatment methods for oncology

Diagnosis of small intestinal cancer is carried out using fibrogastroduodenoscopy and contrast fluoroscopy. Doctors can resort to irrigoscopy to identify tumors in the ileum.

No less important in the process of diagnosing the disease is radiography of the barium passage. Selective angiography of the abdominal organs can provide significant benefits for the correct diagnosis and further treatment of cancer.

The ultrasound method significantly helps to identify metastases and the degree of their development in other organs. To do this, the condition of the internal organs most susceptible to metastasis is carefully examined. Chest radiography, multislice computed tomography of the abdominal cavity (MSCT), and radiological bone diagnostics (scintigraphy) are performed. To clarify some data, diagnostic methods such as laparoscopy or irrigography may be indicated.

Enough attention is paid to the differential diagnosis of the disease. It is important to determine in time the differences between cancer and benign tumors, intestinal tuberculosis, obstruction of mesenteric vessels, Crohn's disease, kidney dystopia, and retroperitoneal tumors. Among female patients, special attention is paid to differentiating cancer from tumors of the internal reproductive organs, congenital small intestinal stasis and colon oncology.

Treatment of small intestinal cancer is complex and requires radical techniques. For this reason, it is often difficult for patients to tolerate. The main methods include:

surgical intervention;
drug treatment;
radiation therapy.

The most effective and frequently used method of treating the disease remains surgery. Resection, or removal of the affected area, can provide the best and most long-lasting results.

Traditionally, two types of surgical intervention are distinguished:

radical (the main goal is complete removal of the source of the lesion, including the problem area and the affected tissue adjacent to it);
palliative procedures (designed to alleviate the patient’s condition and improve the overall quality of his life).

The structure of the organ allows for radical action to remove a tumor that has spread to healthy tissue. Effective treatment methods include transplantation of donor intestinal fragments.

Drug treatment is used in situations where the tumor cannot be removed or is highly sensitive to the effects of chemicals. During chemotherapy, powerful toxins are introduced into the body, aimed at destructive effects on tumor cells. A significant disadvantage of this type of treatment for the disease is its severe course and the development of numerous side effects (death of cells of healthy organs, hair loss, weakened immunity, dyspeptic disorders).

Radiation therapy is an additional method of treating the disease, used to enhance the postoperative effect and course of chemotherapy. The procedure is carried out using special emitting devices. As a result, radiation-sensitive tumor cells are destroyed.

The method does not pose a significant danger to healthy cells of the body, since they have greater resistance to radioactive radiation and are able to effectively withstand it.

Traditional methods of fighting the disease

There is no doubt that small intestine cancer requires the mandatory assistance of qualified specialists and effective treatment methods. The use of traditional methods can play the role of an auxiliary stage aimed at overall strengthening the body and minimizing the manifestations of symptoms of the disease.

Traditional healers offer a variety of recipes to alleviate the condition of people diagnosed with cancer.

Recipe No. 1

It is recommended to use tincture from the pericarp of ordinary walnuts as an effective immunomodulator. To do this you will need 25 nuts and 2 liters of sugar syrup. All ingredients must be mixed, left for at least 3 days and taken two tablespoons daily before meals.

Recipe No. 2

An infusion of calamus root is useful. To prepare it, 30 grams of crushed raw materials must be brewed in 1 liter of boiling water. The warm infusion is taken every morning in small portions.

Recipe No. 3

No less effective is a decoction of buckthorn and chamomile in a ratio of 2 to 1. The mixture of herbs is poured with boiling water and simmered for 10 minutes over low heat. The finished product is taken up to 3 times a day after meals.

Recipe No. 4

Drinking fresh cabbage and pumpkin juice for a month can support the body during illness and treatment of oncology with aggressive chemicals. You must take at least half a glass of natural drink per day.

Such simple recipes can significantly strengthen the immune system and ease the course of the disease.

Prognosis and prevention

A favorable prognosis significantly depends on the period of contact with a medical institution, as well as the stage of development of the disease. Timely diagnosis of a tumor and surgery to remove it significantly increases the likelihood of a complete cure for the patient from cancer.

After surgical intervention at the earliest possible stage, pathological processes are eliminated for a long time. The main postoperative effect is secured by adequate chemotherapy. As a result, the chances of a favorable prognosis for the outcome of the disease increase significantly.

A simple set of preventive measures will help prevent small intestinal cancer. The following should be relevant:

active lifestyle and giving up bad habits;
minimizing stress, nervous exhaustion and physical fatigue;
the presence in the diet of plant foods with a high level of coarse fiber;
minimizing the consumption of foods containing animal fats;
visit a gastroenterologist at the slightest suspicion of manifestations of the disease;
regular visits to a gastroenterologist after 40 years.

Small intestinal cancer belongs to those forms of oncology that, with timely detection and a serious approach to treatment, can be eliminated forever. A considerable number of patients who have undergone an effective course of treatment for the disease continue to live full lives for many years.

Small intestinal cancer is a type of oncology that is not one of the common types. It accounts for no more than 3% of lesions from malignant tumors of the gastrointestinal tract. Symptoms and manifestations of small intestinal cancer in women develop much less frequently, and therefore the disease is mainly diagnosed in older men, that is, over 60 years of age.

Etiology of the disease

The term “intestinal cancer” refers to a malignant tumor that affects the tissue of the intestine with mutagenic cells that begin to divide uncontrollably. Affected cells fill the area, disrupt its functioning, spread to adjacent areas, healthy tissues, and over time infect the entire body. In the absence of necessary treatment, intestinal pathology leads to death.

The length of the loop-shaped small intestine reaches 4.5 m. It consists of several sections: duodenum, jejunum, ileum. Each of them can develop a malignant tumor.

Intestinal cancer is a disease whose exact causes have not yet been established by medical science. There is a list of intestinal pathologies, damage to which provokes an increased risk of developing cancer. This:

the presence of non-polyposis hereditary colorectal cancer;
celiac disease;
congenital anomalies of the structure of the gastrointestinal tract;
Crohn's disease.

One of the factors

Oncology of the small intestine can also occur under the influence of such factors on the human body:

eating foods high in carcinogens;
abuse of alcohol, nicotine;
radiation exposure.

Most often, a malignant tumor begins to affect the cylindrical epithelium of the intestinal glands, and therefore, according to histology, it is classified as carcinoma. Predispose to the occurrence of intestinal disease:

intestinal ulcers;
BPH;
chronic inflammatory processes in the intestines;
diagnosis of diverticulitis.

An intestinal tumor almost always grows into the intestinal lumen, and in isolated cases it is exophytic. Oncology, which expands into the lumen, greatly narrows the intestine in a ring-shaped manner.

The loop of intestine, which is located above the site of narrowing, often expands and its muscles hypertrophy. With severe and long-term stenosis of the lumen, the loop in the intestine stretches, becomes thinner, and perforates, causing peritonitis. This is how patency is impaired due to intussusception.

Oncology rarely undergoes ulceration. It is characterized by metastases to the following organs:

retroperitoneal and mesenteric lymph nodes;
liver;
abdominal region;
lungs;
adrenal glands;
bones;
dura mater.

As a rule, metastases from the intestines spread throughout the body with lymph.

A neoplasm in the intestine can grow together with a nearby loop of intestine, bladder, colon, female genitals, and enlarged regional lymph nodes.

Kinds

A malignant tumor can form anywhere in the small intestine. Oncology is classified into exophytic and endophytic in accordance with the nature of tumor growth. ICD disease code C17 malignant neoplasms of the small intestine.

An exophytic tumor in the intestine grows inside the intestinal lumen. At the very beginning, it provokes stagnation of content in this department. After a certain time, stagnation turns into obstruction.

Endophytic neoplasms do not have clear boundaries. They begin to spread into the intestinal tissue, affecting its layers one by one, gradually affecting all the membranes. With further progression, oncology affects neighboring organs.

An endophytic tumor is more dangerous, and the prognosis for life expectancy and recovery in this case is negative. Intestinal diagnostics helps determine the exact nature of the tumor.

In accordance with the histological structure of tumor neoplasms, they are classified into the following types:

adenocarcinoma is a tumor that affects the glandular tissues of the intestine; it does not form often in the intestine, mainly affecting the duodenum;

carcinoid is a malignant tumor that is formed from epithelial cells, it mainly affects the small and large intestines;
lymphoma is a rare type of ileal cancer;
leiomyosarcoma is a malignant tumor that can reach large sizes, is detected even through the abdominal wall, and often provokes intestinal obstruction.

Carcinoid

Reasons for development

The reliable reasons that cause the formation of oncology have not been established. In accordance with the surveys and statistics, the risk of contracting pathology increases in the following situations:

when a small intestine tumor is diagnosed in a person’s immediate relatives;
with chronic infectious inflammation of the small intestine, which can destroy mucous surfaces;
polyps in the intestine;
oncology of other organs;
radiation exposure;
abuse of alcoholic beverages, smoking;
constant inclusion in the diet of salted, dried, smoked foods, which contain a lot of animal fats, as well as frequent consumption of lard and fatty meats.

Polyps

Important! Most often, oncology of the small intestine is detected in men after 60 years of age.

Characteristic symptoms

A malignant tumor in the small intestine at the very beginning of the lesion does not provoke any symptoms. The first signs develop only at the stage when the course of the disease leads to a narrowing of the lumen in the affected area of the small intestine.

The very first symptoms that should alert a person and become a reason to visit a doctor include complex dyspeptic problems in the intestines:

persistent nausea;
vomit;
bloating;
spastic pain in the epigastrium, in the navel area.

Also, in the first stages of tumor damage, patients experience the following characteristic manifestations:

loose stools with tenesmus - a false urge to defecate with pain, after which there is copious discharge of mucus;
alternating diarrhea and constipation;
intestinal obstruction of varying severity;
pain during bowel movements.

Pain during bowel movements

Common signs of bowel disease include:

rapidly increasing weakness;
frequent ailments;
rapid fatigue even after light work;
loss of appetite;
sudden, seemingly causeless weight loss;
low protein content in blood plasma;
anemia;
pale tint of blood and mucous surfaces that line the oral and nasal cavity;
frequent dizziness, headaches;
persistent increase in body temperature to subfebrile.

In men and women, a tumor in the small intestine develops in the first stages of the lesion almost equally. But at the time of active progression and influence on nearby organs, some differences arise.

In women, during the process of tumor growth into the tissue of neighboring organs, the vagina is injured, and in males, the prostate is injured. When the disease affects the rectum and anal area, women and men complain of intense pain in the anus, in the area of the coccyx, sacrum, and lumbar spine.

Men are especially prone to urinary problems. This indicates tumor growth into the walls of the bladder. This process provokes a rise in temperature to high numbers, infection of the urinary tract in an ascending manner.

Important! Oncology can progress for a long time without provoking complaints at all, and first manifest itself only after the occurrence of serious irreversible complications.

A tumor of the small intestine is characterized by a gradual increase in symptoms, and therefore people do not take them seriously. Over time, the tumor grows and has a negative impact on the functions of neighboring organs. In this case, victims have complaints that indicate the following dangerous conditions of the intestine:

intestinal ischemia;
pancreatitis;
obstructive jaundice.

In especially severe cases, serious disruptions already occur in the functioning of other organs that are located closer to the tumor - pancreas, liver, etc.

Degrees

1st degree. At this stage, the diameter of the tumor does not exceed 2 cm, it does not extend beyond the boundaries of the small intestine and does not grow into the tissue of nearby organs, and no metastases have yet formed.
2nd degree. At this stage of the progression of the malignant tumor, it grows a little more, begins to extend beyond the boundaries of the intestinal wall and affect nearby organs, but there are no metastases. At this stage, the pathological process often involves the cecum, large intestine, and more specifically its part - the sigmoid colon.
3rd degree - the tumor increases greatly and can send metastases to the lymph nodes near the small intestine, but distant metastases have not yet been observed.
4th degree - the tumor has already affected tissues located nearby and provokes multiple metastases to distant systems and organs.

Oncology of the small intestine is characterized by metastasis to the following organs:

abdomen;
liver;
ovaries;
lungs;
pancreas;
bladder;
adrenal glands;
pelvic organs;
lymph nodes in the retroperitoneal region.

Diagnostics

To make a correct diagnosis, the doctor conducts a comprehensive study of the patient’s condition. It includes several methods to increase the accuracy of the results:

Clinical method. The patient is interviewed, visually examined and palpated to establish the circumstances of the development of the disease and the location of the malignant tumor. If the tumor is large, then it can be detected already at this stage of diagnosis.
Laboratory method. Diagnostic tests are carried out to detect anemia, increased ESR, abnormalities in liver tests, and digestive disorders. The presence of indicators of intestinal cancer in the blood - tumor markers - is also checked.

Tumor markers in the intestines are produced in response to the aggressive influence of a malignant neoplasm on the body. They can be of two types. The first are organ-specific, which are produced by affected cells immediately after damage by pathology; in the normal state they are not present in the body. The second type is enzymes, hormones and other biological substances that produce remaining healthy cells.

Endoscopy. Capsule and laparoscopic techniques are implemented.
X-ray with the introduction of a contrast agent. This method allows you to establish the localization of the tumor and diagnose the direction of its growth - into the thickness of the intestine, into the lumen.

Diagnostics

Treatment

Treatment of a malignant tumor in the small intestine depends on the degree of damage to the organ and the type of oncology. In approximately 2/3 of all cases, surgery is performed to remove cancer cells. This helps reduce the intensity of symptoms and increase the patient's life expectancy.

Important! Sometimes the operation has only palliative value, that is, it is performed with the sole purpose of alleviating the patient’s suffering.

When the operation is impossible or the tumor formation is sensitive to the effects of chemotherapy, it is performed. Chemotherapy drugs inhibit the growth of cancer cells, preventing them from multiplying and developing normally.

Radiation therapy is ineffective for small intestinal cancer, which is why it is not performed. This can take place immediately after or during surgery to improve positive results. Radiation therapy is also used when surgery is impossible for some reason.

After surgery is completed, the patient is advised to undergo rehabilitation to eliminate the symptoms of cancer and try to completely get rid of cancer cells. Your doctor may prescribe the following medications:

"Oxaliplatin";
"Leucovorin";
"Fluorouracil."

Chemotherapy

At the same time, radiation therapy is implemented. But all of the above procedures can cause a large number of side effects:

poor health and weakness;
nausea with vomiting;
diarrhea;
constant headaches;
hair loss;
disruption of hematopoietic processes;
mouth ulcers;
dysfunctions of the immune system.

Due to the fact that the patient’s body is difficult to tolerate treatment, he requires the organization of adequate nutrition, which presupposes compliance with the following conditions:

Refusal of products with a high concentration of animal fats;
Consuming fiber in sufficient quantities - fish oil, soy;
Complete cessation of alcoholic beverages and smoking;
To strengthen the immune system, you can use decoctions of medicinal herbs according to folk recipes.

Rejection of bad habits

Important! In severe stages of the pathology, when surgery is not practical, only radiation and chemotherapy are performed to relieve pain and other severe manifestations of oncology.

Forecast

Early diagnosis of the disease is the key to success in treatment. Long-term prognosis for small intestinal cancer depends on the stage at which the diagnosis was made and the histological nature of the malignant tumor. If the pathological process is clearly localized and does not produce regional or distant metastases, then radical resection makes it possible to achieve survival in 35-40% of cases over the next 5 years.

Patients who have been diagnosed with a precancerous disorder must be registered with a doctor and constantly monitor their own health in order to prevent a serious condition. Oncology of the small intestine is a dangerous disease, so if you develop incomprehensible dyspeptic symptoms, you need to seek advice and recommendations from a doctor.
