Adenocarcinoma of the large intestine

Colon cancer is the fourth most popular oncological disease after lung , stomach and breast cancer. This name means malignant tumors of a different nature in the blind, colon, rectum and anal canal. Adenocarcinoma of the colon develops from epithelial tissues, metastases spread through the lymph, so a favorable prognosis is possible only in the early stages of the disease. The irony is that it is almost impossible to detect this type of cancer during the initial appearance of a tumor.

Adenocarcinoma of the large intestine - prognosis

The main difficulty in the treatment of colon adenocarcinoma is that often the tumor cells do not differentiate until the last moment, that is, they continue to grow in an indefinite form, which complicates the diagnosis and purpose of the method of treatment. By the degree of differentiation, the following types are distinguished:

Highly differentiated adenocarcinoma of the large intestine

This species has the most favorable prognosis. The five-year survival rate in this disease reaches 50%. Particularly high chances are in elderly people, since metastases in this case hardly grow and do not penetrate other organs. Young people with adenocarcinoma were much less fortunate. According to medical statistics, with large-bowel adenocarcinoma of the colon with a high degree of differentiation, approximately 40% of young people survive. But there is a very high probability of relapse during the first 12 months after the operation, as well as the development of distant metastases.

Moderately differentiated adenocarcinoma of the large intestine

Such a tumor can be treated much worse because it is not possible to correctly select the active substance for chemotherapy. Point irradiation also does not always help, and surgical intervention without additional methods of treatment does not give a complete cure.

Low-grade adenocarcinoma of the large intestine

This disease is more dangerous than non-diversified species - mucous or colloidal cancer, mucocellular or perstene-cell carcinoma, as well as squamous and glandular squamous cell carcinoma. All of them are distinguished by an aggressive course of the disease, very rapidly and actively expanding and spreading with lymph, gradually capturing huge areas of the epithelium of the intestine and other organs. These types of cancer can not be treated practically, and the prognosis for the patient with such a disease is extremely unfavorable.

Possible treatment of colon adenocarcinoma

Differential adenocarcenoma of the large intestine can not be treated without surgery. In the initial stage of the disease, if the cells can already be accurately attributed to one of the species, removal of the tumor and the adjacent site of the epithelium, point irradiation and chemotherapy is indicated. The patient transfers the indicated procedures it is quite easy and everything that is required of it in the future is regularly monitored so that a relapse can be noticed as early as possible (observed in 80% of cases during the first year after the operation.

If it is a 1-2 stage cancer, the survival rate is very good. At stages 3 and 4 of the adenocarcenoma of the large intestine, surgeons perform an operation to excise the affected area, often this leads to the need to withdraw the gut through the abdominal cavity and install a kalospriemnik. As a result of colostomy, the patient is deprived of the opportunity to defecate naturally, but gets a chance for several more years of life. Chemotherapy and radiation in such cases are less frequent, since the remote part of the intestine is quite extensive. Such treatment becomes possible only a few weeks after the operation.
