This recent study by Professor Asif Muneer and his co-authors examines the clinical characteristics and management of penile intraepithelial neoplasia (PeIN), a rare precancerous condition, based on a large cohort of 345 patients.
The authors distinguish between undifferentiated PeIN, which is strongly linked to human papillomavirus (HPV), and differentiated PeIN, which is associated with lichen sclerosus (LSc). While topical therapies and cryotherapy are utilised, the research highlights that surgical intervention, particularly circumcision, serves as the primary treatment for most cases.
The findings demonstrate that specialised multidisciplinary care leads to excellent outcomes, with only a small percentage of patients progressing to invasive cancer. Furthermore, the source advocates for HPV vaccination and smoking cessation as vital components of a comprehensive preventative strategy.
