    Adjuvant therapy

    Chemotherapy with bowel cancerAfter surgery for colon or rectal cancer, doctors may prescribe supportive therapy.

    Adjuvant therapy administered in the casewhen the tumor is completely removed, but its microscopic structure indicates a large degree of probability of recurrence. This probability increases even more if were affected lymph nodes.

    Causes of cancer spread to other parts andorgans of the body are uncertain. Perhaps the primary tumor cells get into the bloodstream or the lymphatic system, and then they can become the "embryo" formation of new tumors (metastases or secondary cancer) in other parts of the body. The tumors in the initial stage may be so small that they during several years undetectable.


    Adjuvant chemotherapy

    In cancer, colorectal intestine usually administered as a drug adjuvant chemotherapy, known as "5-fluorouracil" (5-FU).

    Typically, 5-FU given in combination with vitamincalled "folic acid". Sometimes drug 5-FU administered together with the drug, which is called "levamisole". It is believed that it affects the immune system.

    Chemotherapy with bowel cancerAntibodies administered to the forearm vein by using a dropper, the procedure lasts for several hours. Treatment is usually performed on an outpatient basis.

    This method is not licensed, because It is currently experimental.

    Chemotherapy in the secondary or progressive cancer (metastases outside the intestine) according to diagnosis

    Many patients after the passage of the first coursetreatment for colon cancer are not faced with any more problems. But, unfortunately, in some patients there is a recurrence of the disease, or cancer spreading to other organs. This cancer is called "secondary" cancer ( "metastasis") intestine. Also, sometimes even at a time when cancer was diagnosed for the first time, there could happen the spread of cancer cells outside the intestine.

    5FU drug can be administered either directly inby injection into a vein of the forearm or in the form of a long process of intravenous infusion. If the preparation is assigned in the form of continuous infusion, it is necessary to resort to the "center line" such as Hickman lines or Portakat. This line is a segment of flexible plastic tubing of small diameter, which is introduced into the main vein, and output to the sternum area. In this position, it is left on during the entire course of treatment designated. This facilitates the introduction of patient medication and avoids the unpleasant sensations that accompany the repeated injections. Before installing the line gives the patient a local or general anesthesia.

    Such treatment can be obtained without a break for a few months, because, as a rule, it gives very weak side effects.

    Studies to determine the most effective mode of administration to the patient the drug 5FU continues.

    There are several wayschemotherapy. It can be carried out in the form of the course, the duration of which is typically a few days. This course takes place the patient in a hospital setting. During the treatment period followed by a period of rest, which lasts several weeks, during which the patient's body returns to normal, getting rid of the side effects of treatment. Number of courses assigned to each individual patient depends on the type of cancer is detected in the patient, and his response to the medication.

    Chemotherapy can also be conducted in the form of weekly injections on an outpatient basis.


    Side effects

During the course of chemotherapy the patient is regularly taking blood samples and make blood transfusions when necessary or injected antibiotics to combat a particular infection.

    Other possible side effectschemotherapy include nausea and diarrhea.
