Would you consider post-operative radiation therapy for resected malignant melanoma with in-transit metastasis?  

In this example, the patient had a resected melanoma with negative margins and the specimen was noted to have two nests of tumor cells in the deep dermis not directly attached to the primary tumor with negative lymph node sampling. Would you offer adjuvant radiation therapy for such a case?
