Abstract

Men with Peyronie's disease (PD) may have an increased prevalence of certain comorbidities, including malignancy. We sought to examine the clinical relationship between PD and subsequent diagnosis of malignancy. Using data from the IBM Health MarketScan claims database from 2007 to 2013, we compared men with PD to a control group of men without PD or erectile dysfunction matched for age and duration of follow-up. We compared incidence of 18 categories of malignancy between both groups using a Cox regression model. In total, 48,423 men with PD and 484,230 controls were identified. The mean age within both cohorts was 50 ± 9.4 years old, and mean follow-up time was approximately 4.4 ± 2.1 years. After being controlled for age, year of evaluation, obesity, smoking, number of outpatient visits, number of urologist visits, and duration of follow-up, men with PD had an increased risk of all cancers (hazard ratio = 1.10, 95% CI = 1.06-1.14), stomach cancer (1.43, 1.06-1.14), testis cancer (1.39, 1.05-1.84), and melanoma (1.19, 1.02-1.38) when compared with controls. The strengths in using the MarketScan database are the anonymous nature of the data, accessibility, and the power provided by the large number of patient visits recorded. Limitations include a lack of detail in certain facets of patient clinical data, and the lack of long-term follow-up to assess the impact of time on other potentially associated conditions. This manuscript is the first to our knowledge to describe a relationship between PD and cancer. Men with PD may be at increased risk for certain malignancies compared with age-matched controls. Further investigation is needed to explore the clinical implications of these findings. Pastuszak AW, Thirumavalavan N, Kohn TP, et al.
