Surgery followed by radiation therapy may be done for large resected lesions with narrow margins. Localized adjuvant radiation therapy consisting of 45 Gy to 50 Gy may also be indicated when there is capillary-lymphatic space invasion and thickness greater than 5 mm.[1] Radiation therapy to the pelvis and groin is given if two or more groin lymph nodes are involved.[2,3]
