[Colon cancer in the experience of Surgical Clinic No. 1, Tîrgu-Mureş. Late postoperative results].

We analyzed the informations concerning the late postoperative evolution for 405 (60%) of 760 patients with colon cancer operated between 1968-1996 in the Surgical Clinic from Tg.-Mureş and we found a global 5-year survival rate of 35.57%. The conclusion after this study was that the most important worsening prognostic factors were the advanced stage evolution of the tumor and the occlusion. The females had a better prognosis than the males. The rural patients had a better prognosis than the urban. In our study the younger age isn't a worsening factor for survival. The patients with a longer history of the symptoms had an unexpected better survival rate than the others. Localization of the tumors at the site of the descending colon and flexures is an important negative prognostic factor. The penetrating feature of the tumor is more important than the lymphatic invasion for prognosis. Subtotal colectomy performed for stenotic tumors of the left colon, even in emergency for occlusions gave us one of the best 5-year survival rate (75%). The histopathologic type of undifferentiated carcinoma and the mucinous adenocarcinoma are associated with the poorest survival rate. The lymphoma has a better survival rate than the carcinoma. The perioperative blood transfusion, even though is associated with a low survival rate it is not an important prognostic factor.
