Abstract
INTRODUCTION: Retinoic acid X receptors play key roles in tumor cell proliferation, differentiation, apoptosis and angiogenesis via transcriptional regulation. Bexarotene is a specific RXRs agonist which has been granted by FDA approval for the clinical treatment of cutaneous T cell lymphoma (CTCL). Its cancer prevention and treatment potentials in various tumors have been under investigation over the past decade. Areas covered: This review summarizes the efficacy and underlying mechanisms of bexarotene for the treatment of multiple cancers based on the launched clinical trials as well as the basic studies. Expert commentary: In general, bexarotene is an active and reasonable chemoprevention and treatment for various cancers and its combination regimen with other cytotoxic agents or targeted drugs may significantly enhance efficacy and at the same time reduce toxicity due to their nonoverlapping side effects. However, only a subpopulation of bexarotene treated patients benefited from bexarotene administration in most cases. The level of RXRs may serve as a preliminary indicator for the bexarotene response in cancers such as non-small cell lung cancer, acute myeloid leukemia, breast cancer, thyroid cancer and melanoma. Further identification and verification of bexarotene response biomarkers may finally lead to the personalized clinical application of bexarotene on cancers beyond CTCL.
