Improving chemoradiotherapy with nanoparticle therapeutics

Chemoradiotherapy has been a key treatment paradigm in cancer management. One of the main research objectives in cancer research has been to identify agents and strategies to improve the therapeutic index of chemoradiation. Recent development of nanoparticle (NP)-based chemotherapeutics offers a unique opportunity to improve the delivery of chemotherapy, which can in turn improve chemoradiotherapy’s efficacy while lowering toxicity. NP-based chemotherapeutics also possess several characteristics that are well suited for chemoradiotherapy. Therefore, NP chemotherapeutics hold high potential in improving the therapeutic index of chemoradiotherapy. This manuscript reviews the NP properties that are favorable for chemoradiation and the rationale to utilize nanotherapeutics in chemoradiation. This review also discusses the preclinical and clinical data on using NP therapeutics in chemoradiotherapy
