Particle Therapy in Primary and Recurrent Skin Cancer

Friday, February 6, 2026, 11:00 AM - 12:00 PM, Online

Non-melanoma skin cancers (NMSC) are the most common cancers in Caucasian populations, particularly affecting the head and neck areas. The incidence rate increases each year, and current treatments can be challenging for patients, especially in advanced cases. In our retrospective cohort study, we assessed the efficacy of weekly hypo-fractionated proton therapy without bolus in treating superficial high-risk NMSC, including basal cell carcinomas and squamous cell carcinomas. This approach showed promising results, offering faster and well-tolerated treatment, particularly suitable for elderly patients. Considering that no bolus was used, despite the superficial location of these tumors, dosimetric validation is needed. The results of our study suggest that this technique could be an effective and safe option, especially in periorificial locations, with reduced treatment time and overall costs. It appears that proton therapy, using hypo-fractionated radiation therapy schedules, provides better tumor management while being less aggressive to underlying healthy tissues.
