BHIVA webinar - ANCHOR Study: results and their implications

Date and Time: Wednesday 28th September 2022, 16:30 – 18:00

Format: VIRTUAL

People with HIV are at higher risk of HPV-related conditions, including anal cancer. CROI 2022 saw the presentation of the Anal Cancer HSIL Outcomes Research (ANCHOR) Study which compared active monitoring with treatment for people with pre-cancerous lesions detected at anoscopy. Treatment led to an almost 60% reduction in anal cancer incidence and the trial was stopped early.

However, many questions remain including the feasibility, cost-effectiveness and longer-term benefit of this strategy, not to mention the impact of HPV vaccination. This special BHIVA session brought together experts in the field to summarise the ANCHOR findings, review ongoing trials in this area and discuss the implications for research and care.

The webinar and PDF presentations are available to view below.
