Abstract
Colorectal cancer (CRC) is the most common malignant tumour of the gastrointestinal tract (GIT). According to TNM - classification (UICC, 1997), T4 is a tumoar infiltrating directly other organs and structures and/or perforating the visceral peritoneum. It is possible to engage both the bodies located adjacent to the colon and rectum, as well as infiltration of other colorectal segments perforating the serosa, e. g. cecum carcinoma infiltrating the sigma. We presented our clinical experience and surgical treatment for 13 years (from May 2001 to May 2013). Patients` data were processed by sex, mean age, tumour location, involvement of tissues and organs, postoperative period and complications. We concluded that the multivisceral resections in one or two stages were necessary for proper surgical treatment in these patients.
