ABSTRACT
A woman 35 years of age suffering from cutaneous and visceral metastatic melanoma was treated with recombinant Interferon alpha 2b (rIFN alpha 2b) subcutaneously 3 X 10(6) U/m2 3 times a week for 3 months with no apparent effect on the course of the illness. Two months after IFN therapy the patient developed cerebral metastasis. A cycle of carmustine, 100 mg/day for 3 days, was given, and complete disappearance of the cutaneous and visceral, but not of the cerebral manifestations was observed. Two consolidation cycles based on vincristine, dacarbazine and lomustine were then administered. The patient died 26 months after beginning treatment with IFN and 18 months after chemotherapy for the cerebral metastasis. No trace of tumor at the cutaneous or visceral level was found at autopsy.

Tumor growth and survival time were followed in rats transplanted with Morris hepatoma 5123 and previously injected with a crude homogenate of the same tumor by the intradermic or intralymphatic route. Female rats treated by the intralymphatic route showed a longer survival time and impaired tumor growth. Male rats did not show any difference.

Male rats were immunized against bovine albumin injected by either intradermic or intralymphatic routes. A significantly higher number of animals treated by the latter route did respond, probably because antigens introduced by this route directly reach lymph nodes, by passing blood and tissue lytic enzymes.

Most the lymphatic system in the rat was directly observed in our experiment by radiological means. The lymphatics of the limbs were firstly revealed by subcutaneous injection of Patent Blue V. Lipiodol was used as radio-opaque compound injected by a micro-technique fully described by the authors.
