Anal cancer incidence and survival: The Surveillance, Epidemiology, and End Results experience, 1973–2000

Anal cancer is a rare malignancy of the anogenital tract that historically has affected women at a greater rate than men.

The authors analyzed changing trends in incidence rates and 5-year relative survival percentages for patients with anal cancer. The publicly available data used in the current study were obtained from the Surveillance, Epidemiology, and End Results (SEER) Program, a system of population-based tumor registries in the United States.
