摘要
As one of the four major means of cancer treatment including surgery,radiotherapy(RT),chemotherapy,immunotherapy,RT can be applied to various cancers as both a radical cancer treatment and an adjuvant treatment before or after surgery.Although RT is an important modality for cancer treatment,the consequential changes caused by RT in the tumor microenvironment(TME)have not yet been fully elucidated.RT-induced damage to cancer cells leads to different outcomes,such as survival,senescence,or death.During RT,alterations in signaling pathways result in changes in the local immune microenvironment.However,some immune cells are immunosuppressive or transform into immunosuppressive phenotypes under specific conditions,leading to the development of radioresistance.Patients who are radioresistant respond poorly to RT and may experience cancer progression.Given that the emergence of radioresistance is inevitable,new radiosensitization treatments are urgently needed.In this review,we discuss the changes in irradiated cancer cells and immune cells in the TME under different RT regimens and describe existing and potential molecules that could be targeted to improve the therapeutic effects of RT.Overall,this review highlights the possibilities of synergistic therapy by building on existing research.
