Outline of Final Research Achievements

Hyperthermia activates the host immune system against cancer whereas the overall mechanisms are yet to be fully elucidated. So far, several mechanisms of anti-cancer activity by hyperthermia have been postulated : increasing cytotoxicity of effector cells such as NK cells against cancer : enhancing maturation of immature DCs via the production of the HSP-tumor antigen complex in tumors : decreasing the numbers of Tregs in tumor tissues and blood; increasing the expression levels of adhesion molecules in cancer cells. Better uses of hyperthermia will be achieved by further understanding of its effects on the immune system. Additionally, clinical data on cancer treatments using hyperthermia in combination with immunotherapy need to be accumulated and evaluated for their respective clinical efficacies. These efforts will lead to the development of efficient combinatory therapies using immune therapy.
