Cancer in people with multidrug-resistant HIV

Retrospective, cohort analysis including people with HIV and 4-class drug resistance (4DR). The 8-year probability of malignancy after first evidence of 4DR was 12%, with an incidence of 1.6/100 person years of follow-up. Cancer risk tended to increase with higher precancer viremia copy-years adjusted for time [per 1 - log10 copies/ml higher: adjusted hazard ratio (aHR) = 1.35; 95% confidence interval (95% CI) = 0.98-1.85] and male sex-assigned-at-birth (aHR = 2.50; 95% CI = 0.86-7.27). Efforts to achieve long-term undetectability, risk factor control, prevention, and more aggressive cancer screening are needed in this fragile population.
