Summary

This study aims to investigate the expression of FAP by phosphor imaging in invasive vulvar squamous cell carcinoma specimens. This in vitro study will include all consecutive tumour specimens stored both in optimal cutting temperature (OCT) compound and formalin-fixed paraffin-embedded (FFPE) from patients with a first diagnosis of vulvar squamous cell carcinoma who underwent surgery at Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.

Detailed description

Vulvar cancer is a rare gynaecological tumour, affecting 2.5 out of 100,000 women per year. The most common histological type is squamous cell carcinomas. Current guidelines suggest 2-\[18F\]fluoro-2-deoxy-D-glucose (\[18F\]FDG) PET/CT for T2 or larger tumours or when metastases are suspected, even though few studies showed controversial results on small series about the diagnostic accuracy of \[18F\]FDG PET/CT for vulvar cancer. The recently developed fibroblast activation protein inhibitor (FAPI), labelled with gallium-68 or fluorine-18, may be a promising diagnostic tool for gynaecological cancers in the field of PET/CT imaging. There is an unmet need to characterize FAP expression at the whole-body level, to assess target expression for disease detection and FAP-directed therapies. This study aims to investigate the expression of FAP by phosphor imaging in vulvar squamous cell carcinoma specimens on OCT compound and FFPE sections.
