To evaluate the effectiveness of regional hyperthermic cytostatic perfusion in patients with malignant melanomas of the extremities, 107 patients were included in a prospective randomized study. In a control group (A, n = 54) the tumors were widely excised, and the regional lymph nodes were dissected. The patients in the perfusion group (B, n = 53) received additional hyperthermic (42 degrees C) perfusion with melphalan. The disease-free survival time was chosen as the criterion for success. An intermediate evaluation (average follow-up observation period of 550 days) revealed a highly significant difference between the groups (P = 0.0001): 21 recurrences in the control group versus four recurrences in the perfusion group. In a second analysis 3 1/2 years after premature discontinuation, 26 recurrences were diagnosed in Group A, whereas only six recurrences were noted in Group B (P = 0.0001). A retrospective analysis of the entire test group revealed the following figures. In Group A seven recurrences in Stage I were diagnosed, seven in Stage II, and 12 in Stage III. In Group B one was observed in Stage I, one in Stage II, and four in Stage III. The level of significance was calculated to be P = 0.05 in Stage I, P = 0.05 in Stage II, and P = 0.01 in Stage III. The results of the study show that additional perfusion in the treatment of extremity melanomas is superior to conventional methods.

D008545	Melanoma	A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.
