  • Title: Combined therapy of xenografts of human pancreatic carcinomas with rTNF-alpha and mitomycin C.
    Author: Klapdor R, Franke N, Bahlo M.
    Journal: Onkologie; 1989 Jun; 12(3):143-7. PubMed ID: 2503798.
    Abstract:
    Based on previously published experimental studies in nude mice indicating that rTNF-alpha as well as mitomycin C are able to induce significant growth inhibition of xenotransplants of gastrointestinal and pancreatic carcinomas we have investigated the antitumor effects of rTNF-alpha (0.8 mg/kg daily for 21 days) and mitomycin C (2.4 mg/kg once weekly, day 1, 7, 14) as single drugs and in combination (0.8 + 2.4) in nude mice bearing xenografts of 4 human pancreatic carcinomas and 1 colorectal cancer. Serum CA 19-9 was measured additionally to tumor growth rate. The results demonstrate that combined treatment is more effective compared to rTNF-alpha and mitomycin C alone. Combined therapy resulted in a significant inhibition of tumor growth in 3 of 5 xenografts and in decrease of tumor volume to less than 50% of the initial values in 2 of 5 tumors. The results support the concept that combinations of cytokines with cytostatics might be of value for treatment of gastrointestinal and pancreatic cancer in vivo.
