Abstract:

Pancreatic cancer is one of the common malignant tumors in the digestive tract. Interstitial fibrosis and immunosuppression are the characteristics of the tumor microenvironment. Increasing studies have confirmed that unique microbial community exists in pancreatic cancer. Bacteria-based intratumoral microbiota can induce tumor inflammation, affect local immunity and regulate tumor metabolism in multiple ways, becoming an important part of tumor microenvironment. The quantity and composition of intratumoral microbiota play a critical role in the incidence and development of pancreatic cancer, and also affect clinical efficacy of chemotherapy and immunotherapy. The association between specific microbiota and pancreatic cancer enables intratumoral microbiota to have the potential to become novel diagnostic and prognostic biomarkers and possible therapeutic targets. In this article, the latest research progress in the composition, role and clinical application value of intratumoral microbiota in pancreatic cancer was reviewed, aiming to provide theoretical basis and useful reference for subsequent research.

Key words: Pancreatic cancer, Intratumoral microbe, Pathogenesis, Treatment
