Regional perfusion for the treatment of subungual melanoma.
Thirty-one patients with subungual melanoma representing 2.6 per cent of all patients with limb melanoma were treated by isolated regional perfusion. Acral lentiginous melanoma prevalent on subungual and volar skin was the most common histologic type. The subungual lesions primarily occurred on the lower limbs (61%) and great toe (48%). At diagnosis, most patients had advanced disease; 53 per cent of stage I patients had lesions with level IV invasion or greater. The median thickness of the primary lesion was 2.35 mm. All patients were treated by isolated regional perfusion and amputation of the involved digit, as well as regional lymph-node dissection where clinically indicated. The mean survival rate for all stages at five years was 35 per cent. Patients with stage I disease had the best survival rates, 61 per cent at five years and 54 per cent at ten years; however, patients with advanced disease, stage III (M.D. Anderson classification), had only a 17 per cent survival rate at five years and 8 per cent at 10 years. Women had slightly better survival rates than men, and patients with upper-limb lesions had the better prognosis.
