Survival of patients with colorectal cancer in Austria by sex, age, and stage

This paper for the first time presents Austrian data on survival of patients, diagnosed from 1998 through 2002, with colon cancer and with rectal cancer. Cumulative relative survival rates were calculated by age, standardized for all ages and stages combined, and by age groups (< 50 years, 50-64 years, and =65 years) according to stages (localized, regional metastases and distant metastases). In carcinoma of the colon 5-year relative survival was 66 % in males and 64 % in females. In carcinoma of the rectum 5-year relative survival was 64 % in males and 67 % in females. Compared to the earlier results from the Tyrol (based on patients diagnosed from 1990 through 1994) the 5-year survival of patients with colon cancer increased from 55 % to 66 % in males and from 58 % to 64 % in females. In patients with rectal cancer 5-year survival increased from 44 % to 64 % in males and from 46 % to 67 % in females. This increase in part can be explained by a positive effect of early detection and of better treatment.
