Genital chronic GVHD in men after hematopoietic stem cell transplantation: a single-center cross-sectional analysis of 155 patients.

We assessed the prevalence and clinical features of genital skin changes in men after allogeneic hematopoietic stem cell transplantation (HSCT) and evaluated the correlation between genital chronic graft-versus-host disease (cGVHD) and other manifestations of cGVHD as well as sexual issues. In a cross-sectional cohort study, 155 male recipients alive 1 year or more after HSCT were assessed during their annual follow-up evaluation. Correlation between genital skin changes and other cGVHD manifestations was evaluated, and post-transplantation sexual contentment and sexual functioning were assessed by 2 self-assessment questionnaires, including the 5-item version of the International Index of Erectile Function (IIEF-5) and the modified Brief Sexual Symptom Checklist (mBSSC). Median time between HSCT and genital examination was 5.9 years (range, 1 to 30.3 years). Thirty-one of 155 patients (20%) presented with genital skin changes. Twenty-one of those (13%) presented clinically inflammatory genital skin changes considered as genital cGVHD: 12 had inflammatory (noninfectious) balanoposthitis, 6 had lichen sclerosis-like lesions, 5 had phimosis, and 2 patients had more than 1 feature. Patients with inflammatory genital skin changes had a significantly higher coincidence of oral (P < .0001), ocular (P < .002), and/or cutaneous cGVHD (P < .026) when compared with patients without genital lesions. The rate of IIEF-5 questionnaire response was 59% (91 of 155). Among them, 67% reported erectile dysfunction. Erectile dysfunction was significantly more frequent in patients with genital cGVHD (P = .0075). Seventy-five of 155 patients (48%) answered the mBSSC questionnaire. Only 40% of them reported sexual contentment. Genital skin changes in male recipients after allogeneic HSCT are frequent and seem to be an under-reported relevant late effect. Inflammatory genital skin changes can be considered as a form of genital cGVHD often associated with manifestations of extragenital mucocutaneous cGVHD.
