OBJECTIVE
To investigate the clinicopathologic characteristics of colonic cancer.
METHODS
All clinical data of surgical cases from hospital registry from 1982 to 2002 were analyzed using SPSS 11.0 software.
RESULTS
There were 1075 patients with colonic cancer including 573 males and 502 females. The median age of the patients was 58 years. 90.8% of the patients aged over 40 years . The proportion of right colonic cancer was 64.7%. Well-differentiated and moderately differentiated adenocarcinoma accounted for 69.8%, and mucous carcinoma 13.6%. The proportions of early stage I, advanced stage II, III and IV cancer were 8.1%, 45.0%, 26.5% and 20.3% respectively. The 5-, 10-year survival rates were 61.9% and 53.0% respectively.
CONCLUSIONS
The risk for colonic cancer is significantly increased in patients over 40 years. The frequency of right colonic cancer is higher than that of left colonic cancer. The overall survival rate is high.
