The presence and prognostic relevance of the intratumoural microbiota in pancreatic cancer, and the roles of intratumoural bacteria in oncogenesis and therapeutic response are beginning to be elucidated. The feasibility of characterizing intratumoural microbial communities from paraffin-embedded tissues has now been validated, providing greater opportunities for retrospective research. Prospective studies are also needed to test the efficacy of rational approaches combining microbial modulation with chemotherapy and/or immunotherapy.
