Peyronie’s Disease in Men Screened for Prostate Cancer in Trinidad

Purpose: To determine the prevalence of Peyronie’s disease (PD) in a specific group of men attending two screening clinics for prostate cancer over a six-month period. Methods: From November 2007 to June 2008, all men attending two screening clinics for prostate cancer were prospectively surveyed. All the men had volunteered to have their prostate checked. Using a structured questionnaire we identified 1,030 cases. The men, who were all volunteers, were from three age group categories: 18–45, 46–60 and over 60 years, and three ethnic groups: Afro-Trinidadian, Indo-Trinidadian and mixed. No written consent was sought from the men to conduct the procedures since they had all come to the clinic, for the purpose of having their prostate checked. However, consent was obtained for individual interviews using a structured questionnaire to determine eligibility for the study. The questionnaire was adapted from universally accepted clinical presentations of PD but was not validated and hence the reliability is not reported. Data were analyzed using the SPSS version 12.0 for Windows. Results: During the six-month period a total of 1,030 men were screened and surveyed. Ages were distributed as follows: Group I included age 18–45 years (n = 220; 21.4%); Group II included age 46–60 years (n= 443; 43.0%), and Group III was composed of over 60 years: (n = 367; 36.5%). The mean age was 58 years with a range between 46 and 75 years. A total of 701 (68%) men were Africans, 182 (17.7%) were East Indians and 147 (14.3%) were of mixed ethnicity. Of the 12 (1.2%) men who satisfied the criteria for PD, 7 (58.3%) were in Group II and 5 (41.7%) in Group III. Ten (83.3%) men with PD were of African origin and 2 (16.7%) were of mixed ethnicity. There were 5 of 12 (41.6%) men with PD who took medication/s for hypertension, 3 of 12 (25.0%) were on treatment for late onset diabetes mellitus and 4 of 12 (33.3%) men received treatments for both conditions. Conclusions: The study found that the prevalence (1.2%) of PD falls within previously observed studies. It also agreed with previous studies which showed that prevalence is highest among 40–60 year olds.
