BACKGROUND: To evaluate the role of definitive weekly hypofractionated radiotherapy (RT) for the treatment of surgery-ineligible elderly patients with cutaneous squamous cell carcinoma of the head and neck region (cHNSCC).
METHODS: Eligible elderly patients (aged ≥75 years) with cHNSCC were included. Patients received definitive weekly hypofractionated RT, using megavoltage electrons, to a total dose of 56-64 Gy (8 Gy per fraction). Primary endpoint was objective response rate (ORR), defined as the percentage of patients with a complete (CR) or partial response (PR). Secondary endpoints included duration of response (DOR), progression-free survival (PFS), overall survival (OS), pain response, tolerability, and safety.
RESULTS: A total of 19 patients with 27 lesions were included and treated with definitive weekly hypofractionated RT. All patients received the prescribed total dose. ORR was 92.6%, including 70.4% of lesions with a CR and 22.2% with a PR. Median DOR was 12 months. No severe toxicity occurred.
CONCLUSIONS: Our study confirmed the satisfying efficacy and acceptable toxicity of definitive weekly hypofractionated RT for cHNSCC in elderly patients. Our results establish weekly hypofractionated scheduleas a promising treatment option for elderly patients with cHNSCC.
