Thoracic duct lymph was drained for 28 days from a patient with disseminated malignant melanoma. Lymphocytes were separated from the lymph by centrifugation, and returned to the patient daily. Biochemical and hematologic parameters were monitored in blood and lymph, and were maintained at satisfactory levels throughout the period. Cell-mediated immunity and specific blocking activity directed against melanoma antigens were examined by the leukocyte adherence inhibition test. Blocking factors in drained lymph fell to undetectable levels after 6 days' thoracic duct drainage, whereas it took 9 days for serum blocking factors to fall to similar levels. Peripheral blood leukocytes demonstrated cell-mediated immunity against melanoma antigens before and throughout the period of drainage, except for the immediate postoperative period. Within 24 hours of closure of the thoracic duct fistula, serum blocking activity had returned, and 17 days later the patient died.
