Abstract

The tumoricidal activities of single dose x-irradiation (RAD) and concomitant Actinomycin D (AMD) with or without local tumor hyperthermia (LTH) on an in vivo methylcholanthrene-induced fibrosarcoma (Meth-A) are described. The addition of LTH enhanced the actions of AMD, RAD and AMD+RAD; The trimodality treatment was most effective. Based on the delay of tumor growth, the radiation dose reduction factors for AMD+RAD+LTH compared to RAD; AMD+RAD+LTH, were approximately 2.8, 2.1, and 1.8, respectively. The shape of the curves suggests a further decrease in the ability of the tumor cell to repair sublethal damage with AMD+RAD+LTH. The clinical relevance is not determined.
