This type of cancer is uncommon, arising mostly in older women and has been neglected in research and clinical trials. Over the recent years, investigators have learned that the most common type of vulvar cancer; vulvar squamous cell carcinoma (VSCC) develops from pre-cancerous lesions via different pathways. One pathway is associated with human papillomavirus (HPV) infection, and another is related to chronic inflammatory skin conditions (and not HPV). The VSCCs arising from these two principal pathways; HPV- associated (HPV A) and HPV-independent (HPV I), behave differently with different risks of recurrence, and different response to treatments. HPV-I VSCC are further defined by mutations in TP53 (Tumor Protein 53), which identify a group of patients with aggressive disease. Currently treatment is the same for all women with vulvar cancer, and consequently many women may be overtreated, and many women are not treated enough. Given evolving knowledge of this disease, this 'one size fits all' approach may no longer be appropriate. The investigators aim in this study is to see if personalizing surgical therapy for patients with vulvar cancer based on HPV and TP53 status will improve outcomes.",[84],"Vulvar Cancer","2026-01-31",{"date":87,"type":88},"2026-02-03","ACTUAL",{"date":90,"type":88},"2024-11-25",{"date":92,"type":78},"2031-11-25",{"name":5,"class":6},1]
