Oral Microbiome and Pancreatic Cancer
Oral Microbiome and Pancreatic Cancer: a Prospective Case-Control Study
This is a prospective population based study to examine the relationship of oral and pancreatic microbiome, and their functions, to pancreatic cancer risk.
The identification of specific oral bacteria and their functional relationship to pancreatic cancer will advance scientific knowledge on the etiology of pancreatic cancer. This could provide a new microbially-based research paradigm, possibly leading to new drug targets for this disease. Second, the oral bacteria may serve as a readily accessible, non-invasive biomarker for subsequent pancreatic cancer risk, which help to identify people at high risk of this disease. Finally, the identified oral bacteria may lead to microbial prophylactic preventions, with antibiotic therapy aimed at eradicating the specific species associated with increased cancer risk or, alternatively, combined with probiotics to introduce species that are associated with a decreased cancer risk. Thus, the study outcomes will lead to actionable means for pancreatic cancer prevention.

介入・治療 |
|---|---|

Cases
subjects with histology-confirmed incident pancreatic cancer, with no prior history of cancer (except non-melanoma skin cancer), a valid consent, and pre-diagnostic oral wash samples.
|
extraction of genomic DNA from oral samples using the Mobio DNA Isolation Kit.
16S rRNA amplicons covering variable regions V3 to V4 will be generated using primers (347F-5'GGAGGCAGCAGTRRGGAAT'-3' and 803R 5'-CTACCRGGGTATCTAATCC-3')66 incorporating adapters and a sample barcode sequence at PI's lab.
Amplicons will be sequenced with the Roche 454 FLX Titanium sequencing system at the NYU genome technology center, following the manufacturer's specifications.

Control
selected by incidence density sampling63 among cohort members who had no cancer prior to selection, provided a valid consent and an oral wash.
Controls were frequency matched to cases by cohort, age at cohort entry (5 year), sex, race, and calendar year of cohort entry.

Presence or absence of bacterial taxa will be compared in oral and pancreatic samples.
時間枠:4 Years
|
For the taxa present at both sites, correlation between the abundance of taxa will be examined between the two sites.
To adjust for confounders, multivariate linear regression will be used with abundance of oral taxa (exposure) and that of pancreas taxa (outcome).
