Abstract
Concurrent chemo and radiation therapies are commonly used to treat locally advanced cancer. Despite improved efficacy, failure rates remain high due to healthy organ toxicity caused by chemo-radiotherapy. Recent technological advances such as nanoparticle encapsulation of anticancer agents, locally controlled irradiation and concurrent use of radio- and nano-medicines are providing innovative solutions for overcoming the limitations of systemic and local treatment toxicities. In this mini-review, we discuss the roles of radiotherapy in generating new therapeutic targets and altering the tumor microenvironment, and we propose their future applications in drug delivery in combination with radiotherapy.
