The aim of this study is to evaluate the outcomes of robot-assisted laparoscopic prostatectomy (RALP) in prostate cancer (PCa) patients with human immunodeficiency virus (HIV). This is a prospective cohort study of HIV patients undergoing RALP, comparing the demographics, tumor characteristics, complications, and short-term oncological outcomes of HIV-positive men to HIV-negative men using univariate (v 2 , Mann-Whitney test) and multivariable (logistic regression) analyses. From 2007 to 2010, 298 men underwent RALP, 8 of whom were known to be HIV positive. Preoperatively, all eight were taking highly active antiretroviral therapy (HAART) and had undetectable viral loads (o50); mean CD4 count was 634 cells per mm 3 . HIV-positive men were younger (54 versus 62 years, P ¼ 0.010) and less likely to be white (P ¼ 0.007). There were no significant differences between groups with respect to clinical staging, pathological and oncological outcomes or most complication rates. However, the prevalence of perioperative transfusions (P ¼ 0.031) and ileus (P ¼ 0.021) were higher in HIV-positive patients. HIV remained significantly associated with risk of transfusion after adjustment for age, race, Gleason sum and clinical T stage (P ¼ 0.002). After a median of 2.6 (range 0.03-19.2) months of follow-up, PSA remained undetectable in all eight HIV patients. These data suggest that RALP is safe for, and demonstrates short-term oncological efficacy in, HIV-positive patients with PCa.
