Aim: In the present study we assessed if postoperative radiotherapy (PORT) using conventional fractionation confers a benefit in cutaneous melanoma patients with lymph node (LN) metastasis. Patients and Methods: Sixty-two patients with axillary or inguinal LN metastasis were retrospectively reviewed. Twenty-eight patients received PORT. The median RT dose was 50 Gy in 25 fractions. The high-risk group was defined by the presence of any of the following: 3 LNs, size 3 cm, extranodal extension. Results: The median follow-up time was 34 months. PORT showed a significant benefit on 5-year axilla-inguinal recurrence-free survival (RFS) in high-risk patients (RT 100% vs. No-RT 37%, p=0.001). There was also a benefit of RT on 5-year out-field RFS in the high-risk population (RT 93% vs. No-RT 29%, p=0.002). There were no grade 2 lymphedemas after RT. Conclusion: PORT using conventional fractionation for high-risk LN metastasis from cutaneous melanoma is feasible with comparable regional control and minimal toxicity.
