Overview
This study explores the relationship between pre-treatment dietary patterns, fecal microbiome, and response to chemotherapy in patients with pancreatic ductal adenocarcinoma.
Description
PRIMARY OBJECTIVES:
I. Evaluate the association between pre-treatment diversity of the fecal microbiome and major pathological response to neoadjuvant chemotherapy in operable pancreatic ductal adenocarcinoma patients.
II. Evaluate the association between pre-treatment HEI-2015 dietary score and major pathological response to neoadjuvant chemotherapy in pancreatic ductal adenocarcinoma patients.
III. Evaluate the association between pre-treatment HEI-2015 dietary score and diversity of the fecal microbiome in pancreatic ductal adenocarcinoma patients.
OUTLINE: This is an observational study.
Patients complete a dietary survey and undergo fecal sample collection on study.
