Radiation therapy for nodal disease in malignant melanoma

Radiation therapy has been widely used for palliative management of inoperable metastatic malignant melanoma. For patients with nodal disease, response rates of approximately 70% have been reported. There are limited data concerning the role of adjuvant irradiation following therapeutic lymph node dissection. In this review, 57 patients with isolated resectable and nonresectable nodal disease have been treated with radiation. The overall response rate is 84% for bulky disease. Large fractions are beneficial. The median disease-free survivals were 11 months after adjuvant treatment and 7 months for those with inoperable disease. The median overall survivals were 20 months and 18 months, respectively. Local control in long-term survivors was excellent. Sixty-five percent of patients developed distant metastases. There is a need for additional studies with the use of adjuvant radiation therapy following lymph node dissection
