Anal cancer, like cervical cancer, is associated with Human Papillomavirus (HPV) infection. HIV+ patients have 38-60 fold increased risk of anal cancer compared to HIV- patients prompting many to suggest routine screening given the success of cervical Pap screening. Our goal is to describe our experience with routine anal Pap screening, determine which patients are most likely to have abnormal results, if anal disease on physical exam is predictive of cytology, and correlate cytology with histology findings. Charts of all patients with an anal Pap followed at the Hospital of Saint Raphael HIV Clinic were reviewed. Demographics, immune status, sexually transmitted disease history, cytology and histology data was extracted from medical charts. Patients with an anal Pap between November 1, 2002-November 30, 2004 were included. Those with an insufficient sample were excluded. Analysis was done using ÷2 for comparison of proportions and student t-test for continuous variables. Overall, 265/560 HIV+ patients had at least one anal Pap. Seventy-four of these 265 patients had an abnormal anal Pap. Mean age was 44 yrs, and 68% were men. Fifty-nine percent were African American, 34% White, and 17% Hispanic. Those with an abnormal Pap were more likely to be White (p=.03), and be gay or bisexual men (p=.02). They were also more likely to have lower CD4+ nadir (142 vs 223, p=.005) and CD4+ at time of anal Pap (353 vs 497, p |
