Abstract
The treatment of anal cancer in patients who are seropositive for HIV (HIV-positive) has been controversial for more than 3 decades. Current treatment guidelines recommend that healthy HIV-positive patients receive standard fluorouracil and mitomycin C concurrent chemoradiotherapy, but some investigators question whether these patients experience more severe toxic effects or worse long-term outcomes that might necessitate a modified treatment approach. This study investigates the influence of HIV status on patient outcomes in a national cohort of US veterans.
