  • Title: Enhancement of bleomycin activity against Lewis lung tumors in mice by local hyperthermia.
    Author: Magin RL, Sikic BI, Cysyk RL.
    Journal: Cancer Res; 1979 Sep; 39(9):3792-5. PubMed ID: 89905.
    Abstract:
    The cytotoxicity of the drug bleomycin in vitro has previously been shown to be enhanced by hyperthermia. This report demonstrates in vivo a more than additive interaction between local tumor hyperthermia (43 degrees, 60 min) and bleomycin (15 mg/kg s.c.) against s.c.-implanted Lewis lung carcinomas in mice. Local hyperthermia was produced by the application of 2450-MHz microwaves to the region of the tumor without induction of significant whole-body hyperthermia. The combined drug and heat treatments were applied to tumors on Days 4, 7, and 10 following implantation. The response of the tumors to simultaneous treatment was a 17-day growth delay compared with controls, whereas the local hyperthermia and bleomycin individually resulted in only 3- and 4-day growth delays, respectively. If the two treatments were given either 4 or 24 hr apart only an additive effect on growth delay was observed.
