The antitumor activity of combination therapy of recombinant human tumor necrosis factor alpha (rHu-TNF alpha) and chemotherapeutic agents against murine bladder tumor (MBT-2) was studied. Tumors were intradermally transplanted into the hind leg of C3H-HeN mice and allowed to grow until they reached a diameter of 8 to 10 mm 10 days after transplantation. TNF (3,000 units) was given intraperitoneally from day 10 to day 19, and the chemotherapeutic agents, 5-FU (60 mg/kg), CPM (100 mg/kg), CDDP (10 mg/kg) and ADM (5 mg/kg), were applied once intraperitoneally on day 10. The antitumor effects were evaluated based on tumor volume on day 20. 5-FU, CPM and ADM enhanced the antitumor effect when combined with TNF, but CDDP did not. These findings suggest that combination therapy of TNF and certain antitumor chemotherapeutic agents is effective cancer treatment.
