Colorectal cancer (CRC) is a frequently diagnosed and lethal disease. The risk of developing CRC is determined by environmental and genetic factors. Surgical treatment is the main curative modality for patients with CRC up to stage III. In recent years, a special place has been given to biological agents used as targeted therapy following the genetic analysis of the tumor: Bevacizumab (Avastin), Cetuximab (Erbitux), Ziv-aflibercept (Zaltrap). We present a study based on 46 colorectal tumor resection specimens from patients operated for CRC in the Surgery Departments of the Emergency County Clinical Hospital of Craiova, Romania. Histopathological examination and immunohistochemistry staining of tissue sections were performed to determine the degree of aggressiveness. Using the Kaplan-Meier test, we calculated the correlation coefficient between survival time and immunohistochemical prognostic factors. The patients were followed for 60 months postoperatively.
