ABSTRACT: BACKGROUND AND AIMS: Risk factors for pancreatic neuroendocrine tumors (PNETs) are not well understood. The aim of this systematic review was to assess if diabetes mellitus, smoking, alcohol use, and family history of cancer are risk factors for PNETs. METHODS: MEDLINE and abstracts from the European and North American Neuroendocrine Tumor Societies (ENETS and NANETS) were searched for studies published until October 2013. Eligible studies were selected according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. RESULTS: Five studies evaluating 4 individual populations were included (study accrual period 2000-2011) into the meta-analysis, involving 827 cases (range 160-309 per study) and 2,407 controls (range 233-924 per study). All studies had a case-control design and described regional series. The pooled adjusted odds ratio was 2.74 (95% CI: 1.63-4.62; p < 0.01; I(2) = 60.4%) for history of diabetes, 1.21 (95% CI: 0.92-1.58; p = 0.18; I(2) = 45.8%) for ever smoking, 1.37 (95% CI: 0.99-1.91; p = 0.06; I(2) = 0.0%) for heavy smoking, 1.09 (95% CI: 0.64-1.85; p = 0.75; I(2) = 85.2%) for ever alcohol use, 2.72 (95% CI: 1.25-5.91; p = 0.01; I(2) = 57.8%) for heavy alcohol use, and 2.16 (95% CI: 1.64-2.85; p < 0.01; I(2) = 0.0%) for first-degree family history of cancer. CONCLUSIONS: Diabetes mellitus and first-degree family history of cancer are associated with an increased risk of sporadic PNET. There was also a trend for diagnosis of sporadic PNET associated with heavy smoking. Alcohol use may be a risk factor for PNET, but there was considerable heterogeneity in the meta-analysis. These results suggest the need for a larger, homogeneous, international study for the clarification of risk factors for the occurrence of PNET.

ABSTRACT: OBJECTIVES: Different diagnostic entities can present as solid pancreatic lesions (SPL). This study aimed to explore the utility of endoscopic ultrasound-guided reverse bevel fine-needle biopsy sampling (EUS-FNB) in SPLs. MATERIAL AND METHODS: In 2012-2015, consecutive patients with SPLs were prospectively included in a tertiary center setting and subjected to dual needle sampling with a 22 gauge reverse bevel biopsy needle and a conventional 25 gauge open tip aspiration needle (EUS-FNA). The outcome measures were the diagnostic accuracy of sampling, calculated for each modality separately and for the modalities combined (EUS-FNA + FNB), and the adverse event rate related to sampling. RESULTS: In 68 unique study subjects, the most common diagnostic entities were pancreatic neuroendocrine tumor, PNET, (34%), pancreatic ductal adenocarcinoma, PDAC, (32%), pancreatitis (15%) and metastasis (6%). The overall diagnostic accuracy of EUS-FNB was not significantly different from that of EUS-FNA, (69% vs. 78%, p = .31). EUS-FNA + FNB, compared with EUS-FNA alone, had a higher sensitivity for tumors other than PDAC (89% vs. 69%, p = .02) but not for PDACs (95% vs. 85%, p = .5). No adverse event was recorded after the study dual-needle sampling procedures. CONCLUSIONS: Endoscopic ultrasound-guided tissue acquisition performed with a 22 gauge reverse bevel biopsy needle is safe but not superior to conventional fine-needle aspiration performed with a 25 gauge open tip needle in diagnosing solid pancreatic lesions. However, the performance of both these modalities may facilitate the diagnostic work-up in selected patients, such as cases suspicious for pancreatic neuroendocrine tumors and metastases.

ABSTRACT: Pancreatic neuroendocrine neoplasms (PNENs) represent 10% of all pancreatic tumors by prevalence. Their incidence has reportedly increased over recent decades in parallel with that of pancreatic adenocarcinoma. PNENs are relatively rare, and of the few institutions that have published potential risk factors, findings have been heterogeneous. Our objective was to investigate the association between potential risk and protective factors for the occurrence of sporadic PNENs across a European population from several institutions. A multinational European case-control study was conducted to examine the association of selected environmental, family and medical exposure factors using a standardized questionnaire in face-to-face interviews. A ratio of 1:3 cases to controls were sex and age matched at each study site. Adjusted univariate and multivariate logistic regression analysis were performed for statistically significant factors. The following results were obtained: In 201 cases and 603 controls, non-recent onset diabetes (OR 2.09, CI 1.27-3.46) was associated with an increased occurrence of PNENs. The prevalence of non-recent onset diabetes was higher both in cases with metastatic disease (TNM stage III-IV) or advanced grade (G3) at the time of diagnosis. The use of metformin in combination with insulin was also associated with a more aggressive phenotype. Drinking coffee was more frequent in cases with localized disease at diagnosis. Our study concluded that non-recent onset diabetes was associated with an increased occurrence of PNENs and the combination of metformin and insulin was consistent with a more aggressive PNEN phenotype. In contrast to previous studies, smoking, alcohol and first-degree family history of cancer were not associated with PNEN occurrence.
