Malignant intestinal tumors can occur in any part of the digestive tract. Neoplasms grow rapidly, affecting surrounding tissues and metastasizing to distant organs with a current of blood and lymph. Pathology most often occurs in people after 40 years. Tablets from bowel cancer - this is one of the methods of treatment, which is aimed at the destruction of cancer cells.

The disease has a classification, on the basis of which the tactics of treatment are:

  1. The mucous membrane gradually disintegrates, pathological changes occur in the cells. In the stomach ulcers and densations are formed, intoxication begins. The patient complains of fever, headaches and general malaise. There are no metastases, lymph nodes are not affected.
  2. The growth gradually increases, but does not block the channel. In this case, there are violations of the normal functioning of the intestine. In feces there are traces of blood, intoxication is increased. The tumor does not metastasize.
  3. The tumor expands and presses on the neighboring organs. More than 1/2 the diameter of the intestine is blocked, the nearby lymph nodes are affected. Malignant cells spread throughout the circulatory system. The general condition of the patient deteriorates sharply.
  4. The lymphatic system is infected with cancer cells that have penetrated into all organs and tissues. Metastases in the whole body, but most of all the liver is affected. This stage is the most dangerous for life, can cause death.

The effectiveness of treatment depends on early diagnosis of the disease. According to statistics, if treatment is started at the first stage, then the survival rate is 90%, the second 70%, the third 50% and the fourth 30-20%. As a therapy, conservative treatment and surgical methods are used. The first option is used in the early stages and to consolidate the results after the operation. The patient is given radiation or chemotherapy, and various pills and injections are prescribed.

The course of treatment lasts from several days to months. The choice of the drug depends on the individual characteristics of the patient. Such treatment causes a number of adverse reactions: nausea, vomiting, general weakness, alopecia, anorexia. Very often chemotherapy is combined with surgical intervention. This method involves cutting off the diseased portion of the intestine and parts of the affected organs. The cut intestine is sewn, removing its ends outwards. This state is difficult, but not life threatening. After treatment, the patient is waiting for a long rehabilitation course aimed at restoring the body.

5-fluorouracil

The active substance of this chemotherapy is uracil antimetabolite-fluorouracil. The mechanism of action of 5-fluorouracil is based on changes in the structure of RNA and inhibition of the division of cancer cells by blockade of the enzyme thymidylate synthetase. Active metabolites penetrate into tumor cells and after a couple of hours their concentration in the tissues of the tumor is much higher than in healthy ones.

The drug is released as a concentrate for the preparation of infusions in ampoules of 250, 500, 1000 and 5000 mg of active ingredient. When administered intravenously, the drug quickly spreads through the fluids and tissues of organisms, penetrates the dorsal and brain. Metabolized to active metabolites, excreted through the lungs and kidneys.
