Aim: To study clinical outcome for oligometastatic patients (abdominal lymph-node metastases) treated with stereotactic body radiation therapy. Materials and methods: Seventy-one patients were studied retrospectively. Dose prescription was 45 Gy in six fractions. Clinical outcome was assessed with actuarial analysis. Results: The median follow-up was 1.5 years; 45 patients (63.3%) had solitary metastasis, and 26 (36.6%) had multiple lesions. Local control was achieved in 97.5% with a 1-year actuarial rate of 83%. Two-year progression-free survival was 63.1%, and the overall survival was 76.9%. Two patients (3%) developed grade 2 gastro-enteric toxicity. Conclusions: The treatment provided adequate clinical response in the management of oligometastatic cases.
