Abstract
The classification of vulvar squamous cell carcinoma (VSCC), as in endometrial cancer, has shifted from the histology-based descriptors toward molecular-based identifiers. Recently, it has been reported that there are 3 genetically distinct and clinically significant subtypes of VSCC: HPV-associated VSCC, HPV-independent/p53 wild-type VSCC, and HPV-independent/p53-mutated VSCC. Each group has different prognostic implications as well as response to treatment, thus reinforcing the need for this 3-tier molecular classification. This molecular subtyping can easily be done on vulvar biopsies using p16 and p53 immunohistochemistry stains to further improve risk prediction and individualized treatment decisions, leading to better patient outcomes.
