  5. 5. Randomized Controlled Trial - GOG Radiotherapy vs Surgery T 1-3 N 0-1 M 0 n=58 (27 in Rt arm) Radiotherapy: 50 Gy at 3cm Results: Groin recurrence 5/27 (18.5%) OS: 60% vs 86% Stehman FB et al., IJROBP, 1992; 24: 389-96

  11. 12. Stehman FB et al. Manavi M et al. Perez CA et al. Conclusions: Primary radiotherapy to the groin results in less morbidity but also in a higher number of groin recurrences compared with surgery. Surgery is still to be considered the cornerstone of therapy for the groin nodes. Van der Velden J, Ansink A, The Cochrane Database of Systemic Reviews
