Abstract

The most common type of cancer in the Czech Republic is the cancer of the colon or rectum. Currently two basic surgical techniques are used for the resection of colon due to colon cancer: either classical (open) or laparoscopic operation. This article provides the analysis of medical data of 524 patients who underwent the surgical resection of colon in the University Hospital in Ostrava during the years 2001-2012 in order to: 1) compare different types of surgical techniques for finding the one which guarantees longer overall survival time and 2) estimate the influence of other patient´s characteristics on mortality risk. The fully parametric Weibull accelerated failure time model was used to answer these questions.
