ABSTRACT: PURPOSE: Poor oral health appears to be a risk factor for pancreatic cancer, possibly implicating the oral microbiota. In this pilot study, we evaluated the characteristics of the oral microbiota in patients with pancreatic ductal adenocarcinoma (PDAC), intraductal papillary mucinous neoplasms (IPMN), and healthy controls. METHODS: Forty newly diagnosed PDAC patients, 39 IPMN patients, and 58 controls, excluding current smokers and users of antibiotics, provided saliva samples. Common oral bacterial species were comprehensively surveyed by sequencing of the 16S rRNA microbial genes. We obtained measures of diversity and the mean relative proportions of individual taxa. We explored the degree to which these measures differed according to respondent characteristics based on individual interviews. RESULTS: PDAC cases did not differ in diversity measures from either controls or IPMN cases. PDAC cases had higher mean relative proportions of Firmicutes and related taxa, while controls had higher mean relative proportions of Proteobacteria and related taxa. Results were generally similar when comparing PDAC to IPMN cases. Among IPMNs and controls combined, younger individuals had higher levels of several taxa within the Proteobacteria. The only other variable consistently related to mean relative proportions was mouthwash use, with taxa within Firmicutes more common among users. CONCLUSIONS: While there were no differences in diversity of the oral microbiota among these groups, there were differences in the mean relative proportions of some taxa. Characteristics of the oral microbiota are not associated with most measures of oral health.

2 Article Weight Loss, Diabetes, Fatigue, and Depression Preceding Pancreatic Cancer. 2016

ABSTRACT: OBJECTIVES: We aimed to determine the severity and co-occurrence of established and potential paraneoplastic conditions in pancreatic cancer (weight loss, new onset diabetes, fatigue, and depression) and their relation to patient characteristics. METHODS: Using information from personal interviews with 510 cases and 463 controls, we obtained adjusted odds ratios for weight loss, long-term and new-onset diabetes, fatigue, and depression before diagnosis. Among cases, we investigated the extent to which these factors occurred together and the characteristics of those reporting them. RESULTS: The adjusted odds ratio for weight loss (>3% of usual weight) was 27.0 (95% confidence interval, 17.1-42.6). Severe weight loss was common (21% of cases lost >15%), and was more common in those previously obese. Diabetes was more common in cases and was strongly associated with weight loss (P < 0.0001). Diabetes in cases more often led to prescription of insulin, compared with controls.Fatigue and depression were significantly more common in cases than controls but not related to weight loss or diabetes. These conditions were not related to stage at diagnosis. CONCLUSIONS: Weight loss, often severe, and new-onset diabetes frequently occur together before diagnosis of pancreatic cancer. Fatigue and depression are also potential precursors of diagnosis.
