Introduction. The colon cancer incidence has increased in the last decades as a result of the populations aging in both developed and developing countries. That is why it has become a world health problem. Objective. To determine the relation between the pathological diagnosis criteria of the colon adenocarcinoma and survival of patients surgically treated due to this disease. Methods. A descriptive and cross-sectional study of 192 patients surgically treated due to colon cancer at "Saturnino Lora" Provincial University Hospital from Santiago de Cuba was carried out during the quinquennium 2000-2004. These subjects had a postoperative follow-up for five years. Results. Patients aged over 49, female sex, and malignancies located in the right colon were predominant. According to Dukes´, Astler´s, and Coller´s classification, most subjects belonged to B stage and the most long-term survival belonged to B₁ stage. Moderately differentiated malignancies were most numerous, although survival was higher for those well-differentiated. Taking into account the Thyroid Node Metastasis´ classification, the higher survival was achieved at stage I, although stage II was predominant. Global survival was equivalent to 3 years. Conclusions. The higher colon cancer survival is achieved if patients are surgically treated when having less advanced evolutionary stages of the disease, well-differentiated malignancies, and tumors located in the right colon. Morbidity and mortality due to this cause could be decreased through an effective program for the early detection of this neoplasia at the primary health care level.
