The antitumor activity of recombinant human tumor necrosis factor (rhTNF) against heterotransplanted human prostatic carcinoma (PC-3) and spontaneous lymphatic tumor metastasis was studied in vivo. The spontaneous lymphatic metastasis of PC-3 tumor was found in approximately 50% of cases. Significant antitumor activity was observed with repeated intratumoral administration of a large dose of rhTNF, not only on the subcutaneous tumor xenografts but also on the lymph node metastases. Strong antitumor activity could be achieved even with the intratumoral administration of a small dose of rhTNF in combination with mild hyperthermia on either the transplanted tumors or on the metastatic tumors.
