Can a global patient registry improve anal cancer care for people with HIV?
NCT ID NCT05328765
First seen Aug 28, 2026 · Last updated Aug 28, 2026
Summary
This study builds a global registry of adults with anal squamous cell carcinoma, both with and without HIV infection. Researchers will collect real-world data on treatments, lab results, and outcomes to compare how the disease progresses in each group. The goal is to identify factors that influence survival and treatment response, which could guide better care for people living with HIV.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this registry could reveal which treatments work best for anal cancer in people with HIV, improving care and survival.
- What could go wrong
- This is an observational registry, not a controlled trial, so it cannot prove cause and effect. Results may be limited by incomplete data or differences between patient groups.
