Poster 544 Increasing Incidence of Anal Cancer in Major US Populations: A SEER Database Study From 1973 to 2011
Author Insight from Jamal A. Ibdah, MD, PhD, FACG, Division Director of Gastroenterology and Hepatology, University of Missouri at Columbia
What’s new here and important for clinicians?
Although anal cancer is increasing in the USA, the distribution and trend according to age and ethnicities has not been fully evaluated. Dr. Ibdah’s team, including Dr. Rubayat Rahman, a senior GI fellow, analyzed the trend of anal cancer in major U.S. race/ethnic groups using the surveillance, epidemiology and end results (SEER) database from 1973 to 2011. SEER database is a high-quality national cancer database covering 28% of the U.S. population.
The analysis showed that anal cancer is increasing in non-Hispanic whites, African Americans and Hispanics, whereas it is stable in American Asians/Pacific Islanders and decreasing in American Indians/Alaska Natives. Under the age of 50 years at diagnosis, the increased trend of anal cancer is significant in African American, more in female African Americans than male African Americans.
As anal cancer is increasing in major U.S. ethnic groups with a particularly increasing trend in African Americans under the age of 50 years at diagnosis, the physician communities should be more vigilant for signs and symptoms of anal cancer in these population groups. These population groups also should be educated in this regard.
