Abstract

Hyperthermia has been shown to enhance the effects of chemotherapeutic agents in a wide variety of cancers. The purpose of this study was to investigate the combined effects of a number of commonly used chemotherapeutic drugs (bleomycin, doxorubicin and cisplatin) with photothermal therapy (PTT)-induced hyperthermia in an in vitro system consisting of human head and neck squamous carcinoma cells and murine lymphocytic monocytes which were used as delivery vehicles for gold-silica nanoshells (AuNS). PTT was accomplished via near infra-red (NIR) irradiation of AuNS. The results showed that PTT combined with cisplatin resulted in only a mild degree of synergism while additive effects were observed for concurrent treatments of PTT and doxorubicin and PTT and bleomycin.
