Abstract

The objective of the present study is to elaborate a prognostic index for qualitative assessment of the operative risk in the surgical treatment of colorectal cancer (CRC).

The documentation of 150 CRC patients, 91 males and 59 females, operated on in the Clinic of Surgery, Marko A. Markov Specialized Hospital of Oncological Diseases of Varna during the period from June 2008 till April 2009 was analyzed. Mean patients` age was 64,2 years (range, 34-84 years).

Seventy patients presented with colon cancer, 76 - with rectum cancer while 4 patients presented with multiple tumour localizations. The risk factors included the following: patient`s age and gender; ASA stage; CRC localization according to ICD of WHO; surgical procedure according to OPCS4 system; emergency; CRC stage according to TNM classification; resection type, and hematocrit level. There were 55 patients with TNM stage I, 80 patients with TNM stages II-III, and 15 patients with TNM stage IV. The most common interventions were anterior resection (in 48 patients), right hemicolectomy (in 41 patients), and sigmoidectomy (in 23 patients). Thirty-day operative lethality rate was zero.

The created data-base can successfully be used for the purposes of CRC prognostication with the patients forwarded to operative treatment.
