New research has identified significant racial and sex-based disparities in survival among patients with locoregional squamous cell carcinoma of the anus, especially in black men, who showed the lowest survival rates.

Squamous cell carcinoma of the anus (SCCA), the most common histologic subtype of anal cancer, is one of the few cancers whose incidence is rising in the U.S., with an especially rapid increase seen in black men. This new study reveals that known disparities in the incidence of this cancer appear to also extend to survival.
