Evolution of COLON Cancer

The colon cancer is increasing in incidence in the western and developed countries.
It is the malignant tumor of major incidence in Spain, if men and women are counted, with 41.441 new cases every year. It will affect 1 of every 20 men and 1 of every 30 women before fulfilling 74 years.

In Spain the survival at the age of 5 is located in this moment over the average of the European countries, with 64 % (the European average is 57 %).
Approximately 54 % of the patients who suffer a colon cancer in Spain survives more than 5 years. It is a question of a global survival, without bearing in mind age, histological type or phase of the illness.

Since Prognoses are mentioned in the Factors paragraph the results of global survival 5 years for each of the clinical stadiums, they are similar to those of the cancer of rectum although in general the prognosis of the cancer of colon is better:
It is important to mention here that the survival of the tumors located with affectation ganglionar (stadium C) has improved of significant form with the application of Adjuvant Chemotherapy (administered after the surgery).

In case of the advanced tumors it is becoming possible to prolong the survival median to more than 2 years.

Many patients with advanced beginning illness, after a time in systemic treatment with chemotherapy, can turn into patients with illness resecable, both of the primary tumor, and of the metástasis, what affects of a very important form in its possibilities of survival.

PURSUIT AND REVIEWS AFTER THE CANCER OF COLUMBUS

As soon as the treatment was finished it is necessary to realize periodic reviews. They are necessary to confirm the state of the patient, to continue and to control the side effects of the treatment and to restore a new treatment as quickly as possible if the colon cancer reappears.
The tests that are usually requested in the periodic reviews after the achievement of a meticulous exploration are usually the following ones:
Colonoscopia: it allows to determine if the tumor has reappeared in the origin place or if there is observed some new polyp, which would be precise to extirpate to prepare a malignant evolution.
Analytical it completes: there decide parameters that indicate us the functioning of the liver (organ where the metástasis appear with more frequency) and of the rest of organs. Also there are requested tumor scoreboards (CEA and Ca 19-9) that serve as orientation in the evolution of the illness.
Abdominal ultrasound scan: it allows to visualize the existence or not of injuries in the liver that make us suspect a metástasis.
Thorax radiography: for her the state of the lungs is valued as regards the appearance of injuries due to the tumor.
Abdominal TAC toraco: to study the whole organism with a skill of major definition than the Rx or the ultrasound scan. It usually alternate in the reviews with two previous explorations.

The risk of reappearance of the illness diminishes in the course of time. For it, during the first two or three years after the diagnosis it is advisable to realize reviews every three or four months. During the years 4th and 5th the reviews can spread something more and are realized every six months. From 5th year the reviews can be done annually.
