December 2017—Gene mutations in HPV-negative penile squamous cell carcinoma: The majority of penile squamous cell carcinomas are caused by transforming human papillomavirus infection. The etiology of HPV-negative cancers is unclear, but TP53 mutations have been implicated. Archival tissue from 108 invasive squamous cell carcinomas from a single pathology institution in a low-incidence area were analyzed for HPV-DNA and p16INK4A overexpression and for TP53 mutations by Ion Torrent next-generation sequencing.
