ABSTRACT
Microwave ablation,as a minimally invasive therapy,causes focal hyperthermic injury to ablated tumors.It also induces anti-tumor immunity which could contribute to another mechanism of tumor destruction.Combination with immunotherapy could further enhance the tumor-specific immunity,lead to stronger inhibitory effects on both primary and metastatic lesions and decrease recurrence and metastasis.Thus,combination of microwave ablation and immunotherapy is a promising approach in the treatment of solid tumors,especially for advanced cancers.This article reviews recent advances in the mechanism and application of immune effect induced by microwave ablation.
ABSTRACT
Tumor thermal ablation therapy has been the common minimally invasive technique because of its excellent efficacy and safety,and has become a promising clinical minimally invasive treatment.But there are still limitations in its therapeutic range.Moreover,as an effective local treatment,the technology is bound to a cooperation with tumor system treatments.This review provides an overview of the concept of tumor thermotherapy and thermal ablation,and the possible mechanism of the synergistic effect of the thermal ablation with chemotherapy,including hyperthermia changing the blood supply to improve drug distribution,hyperthermia increasing drug intake,hyperthermia modifying the cytotoxicity of many chemotherapeutic agents,combination therapy improving the rate of complete ablation and promoting cell apoptosis.
