Purpose/Objective:

Oligometastatic disease in head and neck squamous cell carcinoma (HNSCC) is an atypical scenario. Local ablative treatments are the most adopted strategies although no evidence-based recommendations are currently available. The purpose of our analysis was to update and report on long-term clinical outcomes of a cohort of HNSCC patients treated with stereotactic body radiotherapy (SBRT) for lung-only oligometastatic disease.

Material/Methods:

Patients with 1 to 5 pulmonary metastases were included. The oligometastatic pattern was defined as “de novo” or “oligoprogressive” according to ESTRO/EORTC consensus recommendations. We evaluated time to progression
