Bidirectional and dynamic interaction between the microbiota and therapeutic resistance in pancreatic cancer

Biochim Biophys Acta Rev Cancer. 2021 Jan;1875(1):188484. doi: 10.1016/j.bbcan.2020.188484. Epub 2020 Nov 24.

Abstract

Pancreatic ductal adenocarcinoma is one of the most lethal malignancies and is known for its high resistance and low response to treatment. Cancer treatments can reshape the microbiota and in turn, the microbiota influences the therapeutic efficacy by regulating immune response and metabolism. This crosstalk is bidirectional, heterogeneous, and dynamic. In this review, we elaborated on the interactions between the microbiota and therapeutic resistance in pancreatic ductal adenocarcinoma. Regulating the microbiota in pancreatic tumor microenvironment may not only generate direct anti-cancer but also synergistic effects with other treatments, providing new directions in cancer therapy.

Keywords: Immunotherapy; Microbiomes; Pancreatic cancer; Therapeutic resistance.
