CEA and relapse after the operation of colorectal carcinoma.

Background: Relapses have an important meaning in relation to the curative surgical intervention. In RO resections according to UICC classification, the local relapses were classified as the most important factor for survival. Without any doubts the most important of these tumor-biological prognostic factors in patients with colorectal carcinoma is the carcino-embryonal antigen.

[Preoperative levels of CEA and survival in patients with surgical treatment of colorectal carcinoma].

From the 1st January 1986 until the 31st December 1995 397 patients were operated on at the IInd Surgical Clinic of Medical Faculty, Comenius University in Bratislava because of colorectal cancer. Of them 325 patients were operated on electively and 72 patients were operated on as emergency cases. The authors analysed average survival time and the relationship between survival and preoperative level of CEA.

[The effect of age and risk factors on postoperative complications and mortality in patients with surgery for colorectal carcinoma].

The authors analyzed the risk factors and their impact on perioperative complications and mortality in aged patients electively operated due to colorectal cancer at the II. Surgical Clinic LFUK in Bratislava during the period from January 1, 1986 to October 31, 1994. The patients were divided into three groups according to WHO criteria, those younger than 65, from 65 to 75, and older than 75 years of age.
