To synthesize current evidence regarding the existence, spatial distribution, biological function, and therapeutic relevance of the intratumoral microbiome in pancreatic ductal adenocarcinoma.
Narrative review of English-language literature searched across PubMed/MEDLINE, Scopus, Web of Science, and Google Scholar.
Evaluated studies covering tumor-resident bacteria and fungi, tumor microenvironment crosstalk, spatial and single-cell profiling, contamination control, and treatment response.
Low-biomass bacterial and fungal communities reside within pancreatic tumors, spatially organizing into specific hypoxic, immune, and stromal niches.
Tumor-resident microbes interact with myeloid cells, T cells, and cancer-associated fibroblasts to drive immune reprogramming, metabolic stress, and resistance to therapy.
