Brief Summary: The goal of this observational study is to use endoscopic ultrasound-guided fine-needle biopsy EUS-FNB to investigate the intratumoral microbiome profile in patients with pancreatic ductal adenocarcinoma PDAC and to evaluate its potential impact on tumor diagnosis and prognosis PDAC is the most common and lethal type of pancreatic cancer accounting for over 85 of all pancreatic cancer cases Given that most patients are diagnosed at an advanced stage when surgery is no longer an option EUS-FNB serves as a crucial and minimally invasive method for accessing and analyzing the microbiome within the tumor

The main questions this study aims to answer are

Can EUS-FNB reliably and accurately detect the microbiome within PDAC tumors

Researchers will analyze tissue samples obtained through EUS-FNB to confirm its ability to accurately capture the diversity and composition of the tumor microbiome

Are there specific microbes or metabolites within the PDAC tumor microbiome that are linked to patient prognosis or response to chemotherapy

The study will screen for and identify key microbial species or metabolites associated with treatment outcomes and patient survival in PDAC

To ensure the reliability of the EUS-FNB results researchers will systematically compare microbiome data obtained from EUS-FNB samples with those from surgical biopsies of pancreatic cancer tissue This comparison will help validate the consistency and accuracy of the two methods in identifying the microbiome diversity and composition confirming the clinical and research utility of EUS-FNB

Participant Requirements

Participants will be patients diagnosed with PDAC who require EUS-FNB as part of their clinical assessment and treatment pathway

During the EUS-FNB procedure researchers will use the remaining tissue after rapid on-site evaluation ROSE to conduct microbiome sequencing ensuring sample quality

All participants will provide informed consent allowing the use of leftover tissue for microbiome analysis and their privacy will be strictly protected throughout the study

Study Procedures

Participants will undergo a standard EUS-FNB procedure as part of their routine clinical care with no additional procedures required for the study

Researchers will compare the microbiome characteristics from EUS-FNB samples with those from surgical biopsy samples to verify consistency

The study will utilize 2bRAD-M metagenomic sequencing technology which is cost-effective and suitable for low-biomass host-contaminated and degraded microbiome samples This method generates an accurate species-level taxonomic profile for analysis

By identifying key microbial components or metabolites linked to patient prognosis or treatment response this study aims to provide scientific evidence for early detection strategies and effective treatment plans for PDAC patients potentially bringing significant clinical benefits
