Dr. Juan de la Ossa, a general surgeon at The Polyclinic, is working with researchers across the United States, to enroll participants in a clinical trial on anal cancer prevention in HIV patients.

Anal cancer rates among men and women with HIV are rising. Early detection and treatment of anal cancer before symptoms develop, can improve the effectiveness of treatment and minimize the need for debilitating chemotherapy, radiation and surgical interventions.

What is the ANCHOR study?

The ANCHOR study (Anal Cancer HSIL Outcomes Research) will help determine the standard of care for screening and prevention of anal cancer and will also provide insights into the natural history of HPV-related neoplasia.

Who is eligible to participate in the study?

HIV-positive men and women ages 35 and older. Participants will receive $100 compensation at their screening visit.
