| Abstract: | The administration of chemotherapy by isolated regional perfusion was developed in 1957 at Tulane University and was found to be of greatest benefit for patient with melanoma of the limbs. From 1957 to 1984, 897 patients were treated by this method. The 10-year survival rate for 831 patients with primary melanoma was 77 per cent. Women survived longer than men, with 10-year rates of 81 per cent and 65 per cent, respectively. Prophylactic lymph node dissection was of benefit for males with poor prognosis distal lower limb lesions, but other groups did not benefit. Primary lesions on the arm and thigh did better than lesions of the hand or foot, with plantar and subungual lesions having the least favorable results. Thickness, level, and histologic type were also significant prognostic indicators. Thirty-three patients with locally recurrent melanoma (stage II) treated by perfusion and excision had a 10-year survival rate of 59 per cent. For 129 patients with metastases to the regional lymph nodes (IIIB), perfusion plus RLND produced a 10-year rate of 51 per cent; survival rates for those with a single positive node was 64 per cent. Seventy patients with satellitosis or intransit metastases (IIIA) had a 10-year survival rate of 23 per cent. Thirty-eight patients with metastases to limbs from unknown primaries had a 10-year survival rate of 52 per cent. The overall 10-year rate for all stage III patients was 41 per cent. Perfusion produced useful palliation in 144 patients with limb melanoma in the presence of systemic metastases. |
