Brief Summary
The MA-PPING is a multicenter prospective observational study that includes patients undergoing surgery for gastrointestinal cancer. The study aims to map the oral and gut microbiome of patients diagnosed with pancreatic, esophageal or colorectal cancer during their surgical patient journey from the moment of diagnosis until full recovery (three months after surgery).

Outcome Measures
Primary Outcomes (1)
Compositional changes of the oral and gut microbiome, assessed by alpha-diversity using 16S rRNA (ribosomal ribonucleic acid) sequencing, described in a surgical patient journey from moment of diagnosis until full recovery
Changes of the microbiome composition during the surgical treatment quantified as alpha-diversity by 16S rRNA sequencing. Samples will be collected on 7 moments, starting one month before surgery until three months after surgery.
4 months
Secondary Outcomes (5)
Compositional changes of the oral and gut microbiome, assessed by beta-diversity using 16S rRNA sequencing, correlated with neo-adjuvant therapy
1 month
Compositional changes of the oral and gut microbiome, assessed by beta-diversity using 16S rRNA sequencing, correlated with antibiotic prophylaxis
1 week
Compositional changes of the oral and gut microbiome, assessed by beta-diversity using 16S rRNA sequencing, correlated with bowel preparation
1 week
Compositional changes of the oral and gut microbiome, assessed by beta-diversity using 16S rRNA sequencing, correlated with selective decontamination of the digestive tract (SDD)
1 week
Compositional changes of the oral and gut microbiome, assessed by beta-diversity using 16S rRNA sequencing, correlated to the development of infectious complications (30-day)
1 month
Eligibility Criteria
All adult patients who are presented/present at the participating hospitals with a proven gastrointestinal malignancy and scheduled for surgery.
You may qualify if:
- Patients with proven malignancy of the distal esophagus, pancreatic head/corpus, colon or rectum
- Patients undergoing primary elective surgery with construction of an anastomosis of the gastrointestinal tract
- Adult patients above age 18 years
- Written informed consent
You may not qualify if:
- History of chronic gastro-intestinal disease e.g. Crohns disease and ulcerative colitis
- Presence of acute gastrointestinal infection
- Chronic use of oral antibiotics (3 months or longer)
- Patients undergoing gastrointestinal surgery for gastrointestinal cancer in acute setting
- Patients undergoing construction of an end/loop colostomy or ileostomy (following primary resection)
- Patients undergoing colon and/ or rectal resection without construction of an anastomosis
- Patients who have insufficient knowledge of the Dutch language
- Patients who are not able to give reliable answers to the questionnaires due to a (mental) disease or (cognitive) condition
- Patients who are not able to collect microbiome samples due to a physical or mental condition
