PURPOSE: Colorectal cancer (CRC) is a major cause of death in the western world and a leading cause of cancer-related death. It is one of the most common human malignancies with >300,000 cases both in the United States and in the European Union each year. The present study was conducted to assess differences in various variables of CRC, such as location of the tumor, differentiation, Dukes classification, 5-year survival and possible changes in these patterns during the examined period. METHODS: We collected data on 2000 patients with colorectal cancer, diagnosed and treated from 1960 to 2008 in 1st Propedeutic Surgical Clinic of Aristotle's University, Thessaloniki. RESULTS: Of 2000 cases reviewed, cancer was almost equal presented to both sexes, for all groups. Rectum was the most common tumor location in all analyzed groups (40.1%). The most common tumor differentiation was the moderate one (68.5%). Concerning tumor staging, Dukes' B tumors were most common (42.5%), and the cancer-related 5-year survival was increased by the time from 42 to 71%. CONCLUSION: In the past 20 years, considerable improvements have been made in colorectal cancer therapy, and patients had received more sophisticated and multidisciplinary treatments, resulting in a better 5-year survival rate.
