[Surgical treatment and prognostic factors in colorectal cancer]

The aim of this study was to make a contribution to improve the care of patients with colorectal cancer by optimizing times and methods of the follow-up; particular attention is given to factors which may be important for the prognosis and for the quality of life in the immediate postoperative period.

The study includes all the patients with colorectal cancer who underwent laparotomic surgical treatment from 1996 to 2003. The total number of patients was 226 with an average age of 65 years; male to female ratio was 1.57:1. According to the stage of tumor, an adjuvant radiotherapeutic and/or chemiotherapeutic treatment was associated to surgery.

On the basis of the preoperative staging and tumor localization, our patients underwent: 3 total colectomies, 57 right hemicolectomies, 137 left hemicolectomies, 6 Hartmann resections, 19 Miles resections, 4 transverse resections.

The results obtained show that the 5-year overall survival is particularly influenced by the stage and the factors which directly or indirectly affect the primary tumor; thus the prognostic factors which should be considered for the survival and in the follow-up of these patients are: stage, grading and nodal involvement of the tumor.
