Summary
The tumor microbiome influences pancreatic cancer (pancreatic ductal adenocarcinoma, PDAC) development and outcomes. Understanding intratumoral microbes is key for new diagnostic and therapeutic strategies, but contamination challenges must be addressed.
Area of Science:
- Oncology
- Microbiology
- Gastroenterology
Background:
- Microorganisms are increasingly recognized in cancer development, impacting various cancer hallmarks.
- The tumor microbiome's role in pancreatic ductal adenocarcinoma (PDAC), an aggressive cancer with poor survival, is a growing area of research.
- Current therapeutic options for PDAC are limited, highlighting the need for novel treatment strategies.
Purpose of the Study:
- To review the clinical and translational significance of the microbiome in pancreatic ductal adenocarcinoma (PDAC).
- To explore microbial compositions in healthy and cancerous pancreatic tissues.
- To discuss the microbiome's role in PDAC pathogenesis, diagnosis, treatment, and prognosis.
Main Methods:
- Literature review synthesizing current scientific knowledge on the PDAC microbiome.
- Analysis of microbial compositions in healthy versus tumoral pancreatic tissue.
- Discussion of challenges in intratumoral microbiome analysis, including microbial contamination.
Main Results:
- Recent data reveal significant insights into the tumoral microbiome's impact on PDAC survival and therapeutic potential.
- Distinct microbial compositions exist in healthy and PDAC tissues.
- Contamination is a major challenge in analyzing the intratumoral microbiome, affecting reproducibility and relevance.
Conclusions:
- The microbiome plays a critical role in pancreatic ductal adenocarcinoma (PDAC) pathogenesis, diagnosis, treatment, and prognosis.
- Addressing contamination issues is crucial for accurate intratumoral microbiome analysis.
- Defining a reproducible intratumoral microbial composition is essential for leveraging the microbiome as a diagnostic or therapeutic tool in PDAC.
