Race Is Associated With Burden of Anal Condyloma and Need for Operative Intervention

Human papillomavirus is a common sexually transmitted infection that may affect the oropharynx, genitalia, or anus. Some strains of this virus may cause bulky growths around the anus known as giant anal condylomas. These can become large, disfiguring, and may cause bleeding, as well as difficulty with defecation and hygiene. Surgical management is usually necessary for large condylomas, whereas office-based procedures are common for smaller lesions. It is unclear why some develop large anal margin tumors, whereas others develop limited disease. The aim of the present study was to evaluate for risk factors that may play a role in the development of extensive disease warranting operative management.

A retrospective chart review of patients seen within the Anal Dysplasia Clinic at the Medical College of Wisconsin was undertaken. Clinic encounters for patients with anogenital condyloma were abstracted for demographic information, operative interventions, Human Immunodeficiency Virus status, and smoking history to determine risk factors that predicted operative intervention for giant anal condylomas.

A total of 239 patients met inclusion criteria; 211 (88.3%) were male and 28 (11.7%) were female. Racial makeup of the cohort included 49% Caucasian, 38.9% African-American, 9.2% Hispanic, and 2.9% were identified as another ethnicity. One hundred forty-three patients (60.1%) were current or past smokers. One hundred ninety-eight (82.8%) patients tested positive for human immunodeficiency virus (HIV), whereas 41 (17.2%) were negative. Multiple linear regression identified only African-American race as predictive of greater disease burden.

African-American race was associated with increased size of anal condyloma. As the size of anal condylomas increase, management shifts from topical treatments to operative intervention. This is the first study to correlate race with burden of disease in the general population.
