OBSERVATIONAL
The Role of the Human Microbiome in Patients After Pancreatic Resection.
The goal of this observational study is to classify patients that undergo pancreatic resection for presumed pancreatic or periampullary malignancy into high and low risk groups for postoperative complications based on longitudinal saliva, rectal/faecal, tumor, blood and/or bile microbiome profiles. To identify the dynamics of the microbiome, as well as the possibly related short-term and long-term complications, multiple samples at different timepoints are needed from the patients.
Rationale: Resection is the only potentially curative option for pancreatic and periampullary cancer, a complex procedure with a high risk of complications of 30% to 73%. Research shows the presence of altered bacterial populations within fecal, pancreatic fluid, bile and jejunal samples of patients after pancreatic resection compared to healthy samples. Moreover, specific gut microbial composition in the pre- and postoperative period were associated with a higher risk of developing complications after pancreatic resection in small studies. Further research on a larger scale is necessary to validate these findings and to evaluate targeted microbiome modifications to improve outcomes in patients after pancreatic resection. Objective: The primary objective of this study is to classify patients that undergo pancreatic resection for presumed pancreatic or periampullary malignancy into high and low risk groups for postoperative complications based on longitudinal microbiome profiles. Study design: Prospective observational cohort study. Study population: 200 adult patients with resectable pancreatic or periampullary presumed (pre)malignancy. Main study parameters/endpoints: The primary endpoint is a composite of postoperative complications including pancreatic fistula, bleeding, gastroenterostomy-, bile- or chyle leakage, delayed gastric emptying, cholangitis, sepsis and organ failure. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: All participants will be offered the standard of care. In addition, rectal swabs, faeces, salivary, bile, blood and tumor samples will be collected at different time points perioperatively. Participating in this study carries no additional risks.

Primary Outcome Measures | Measure Description | Time Frame |
---|---|---|
Risk stratification postoperative complications | The primary objective of this study is to classify patients that undergo pancreatic resection into high and low risk groups for postoperative complications, based on saliva, blood, tumor, bile and/or rectal/faecal microbiome profiles. | - (Before start chemotherapy), peroperative, preoperative, postoperative day 1/3, +/- 2 weeks post-discharge |
Secondary Outcome Measures | Measure Description | Time Frame |
---|---|---|
Long time oncological outcomes - site of recurrence | Secondary objectives include, but are not limited to, finding associations between microbiome profiles and long term oncological outcomes (e.g. site of recurrence). | - (Before start chemotherapy), peroperative, preoperative, postoperative day 1/3, +/- 2 weeks post-discharge |
Long time oncological outcomes - disease free survival | Secondary objectives include, but are not limited to, finding associations between microbiome profiles and long term oncological outcomes (e.g. disease free survival). | - (Before start chemotherapy), peroperative, preoperative, postoperative day 1/3, +/- 2 weeks post-discharge |
Long time oncological outcomes - overall survival | Secondary objectives include, but are not limited to, finding associations between microbiome profiles and long term oncological outcomes (e.g. overall survival). | - (Before start chemotherapy), peroperative, preoperative, postoperative day 1/3, +/- 2 weeks post-discharge |
Complications neoadjuvant chemotherapy | Secondary objectives include, but are not limited to, finding associations between microbiome profiles and complications of neoadjuvant chemotherapy. | - (Before start chemotherapy), peroperative, preoperative, postoperative day 1/3, +/- 2 weeks post-discharge |
Complications adjuvant chemotherapy | Secondary objectives include, but are not limited to, finding associations between microbiome profiles and complications of adjuvant chemotherapy. | - (Before start chemotherapy), peroperative, preoperative, postoperative day 1/3, +/- 2 weeks post-discharge |
Response to neoadjuvant chemotherapy | Secondary objectives include, but are not limited to, finding associations between microbiome profiles and response to neoadjuvant chemotherapy as judged by computed tomography (CT) scan and histological respons. | - (Before start chemotherapy), peroperative, preoperative, postoperative day 1/3, +/- 2 weeks post-discharge |
Complications bile duct drainage | Secondary objectives include, but are not limited to, finding associations between microbiome profiles and complications associated with bile duct drainage. | - (Before start chemotherapy), peroperative, preoperative, postoperative day 1/3, +/- 2 weeks post-discharge |
Postoperative endocrine insufficiency | Secondary objectives include, but are not limited to, finding associations between microbiome profiles and postoperative endocrine insufficiency (defined as need for new pharmacologic intervention). | - (Before start chemotherapy), peroperative, preoperative, postoperative day 1/3, +/- 2 weeks post-discharge |
Postoperative exocrine insufficiency | Secondary objectives include, but are not limited to, finding associations between microbiome profiles and postoperative exocrine insufficiency (defined as need for new pharmacologic intervention). | - (Before start chemotherapy), peroperative, preoperative, postoperative day 1/3, +/- 2 weeks post-discharge |
