ABSTRACT: Changes in diet, lifestyle, and exposure to environmental risk factors account for the increased incidence of pancreatic disorders, including acute and chronic pancreatitis, and pancreatic cancer. The role of the microbiota in the development of pancreatic disorders is increasingly acknowledged. The translocation of gut bacteria and endotoxins following gut barrier failure is a key event contributing to the severity of acute pancreatitis, while small intestine bacterial overgrowth is common in patients with chronic pancreatitis and further worsens their symptoms and malnutrition. Specific molecular mimicry link the microbiota and Helicobacter pylori with autoimmune pancreatitis. Changes in the oral microbiota typical of periodontitis seem to be associated with an increased risk of developing pancreatic cancer. The composition of the gut microbiota is also unbalanced in the presence of risk factors for pancreatic cancer, such as obesity, smoking and diabetes. Helicobacter pylori infection, atrophic body gastritis and related decreased gastric acid secretion also seem associated with the risk of pancreatic cancer, although this area needs further research. The link between dysbiosis, immune response and proinflammatory status is most likely the key for these associations. The present review article will discuss current available evidence on the role of gut microbiota in pancreatic disorders, highlighting potential areas for future research.

2 Review Management of pancreatic cysts: a review of the current guidelines. 2015

ABSTRACT: The number of patients diagnosed with cystic pancreatic neoplasms (CPN) has increased significantly during the last decade due to the widespread use of cross-sectional imaging. These CPN consist of a heterogeneous group of neoplastic and non-neoplastic lesions with variable histopathological features, clinical presentation, and outcome. Until now we are not able to reliably identify all CPNs that require additional analysis, surgical resection or surveillance. Hence, physicians and surgeons are confronted with a difficult dilemma as they do not want to miss a diagnosis of pancreatic carcinoma, but this often leads to the risk of over- or misuse of diagnostic examinations with a risk of complications and increased health care costs. Currently, four expert consensus guidelines on cystic lesions of the pancreas are available. Unfortunately, recommendations vary considerably between these guidelines. The purpose of this review therefore was to compare the different guidelines and elaborate upon the topics where these guidelines disagree.

ABSTRACT: Different inflammation-based scores such as the neutrophil/lymphocyte ratio (NLR), the Odonera Prognostic Nutritional Index (PNI), the Glasgow Prognostic Score, the platelet/lymphocyte ratio, and the C-reactive protein/albumin ratio have been found to be significantly associated with pancreatic cancer (PDAC) prognosis. However, most studies have investigated patients undergoing surgery, and few of them have compared these scores. We aimed at evaluating the association between inflammatory-based scores and PDAC prognosis. In a single center cohort study, inflammatory-based scores were assessed at diagnosis and their prognostic relevance as well as that of clinic-pathological variables were evaluated through multiple logistic regression and survival probability analysis. In 206 patients, age, male sex, tumor size, presence of distant metastasis, access to chemotherapy, and an NLR > 5 but not other scores were associated with overall survival (OS) at multivariate analysis. Patients with an NLR < 5 had a median survival of 12 months compared to 4 months in those with an NLR > 5. In the 81 patients with distant metastasis at diagnosis, an NLR > 5 resulted in the only variable significantly associated with survival. Among patients with metastatic disease who received chemotherapy, the median survival was 3 months in patients with an NLR > 5 and 7 months in those with an NLR < 5. The NLR might drive therapeutic options in PDAC patients, especially in the setting of metastatic disease.

ABSTRACT: BACKGROUND: About 10% of pancreatic cancer patients are aged ≤50 at diagnosis and defined as Early Onset Pancreatic Cancer (EOPC). There is limited information regarding risk factors for EOPC occurrence and their outcome. AIM: To investigate risk factors, presentation features and outcome of EOPC patients. METHODS: Consecutive, histologically confirmed, pancreatic cancer patients enrolled. Data regarding environmental and genetic risk factors, clinical and pathological information, treatment and survival were recorded. EOPC patients (aged ≤50 at diagnosis) were compared to older subjects. RESULTS: Twenty-five of 293 patients (8.5%) had EOPC. There was no difference regarding sex distribution, medical conditions and alcohol intake between EOPC and older subjects. EOPC patients were more frequently current smokers (56% vs 28% p = 0.001) and started smoking at a significantly lower mean age (19.8 years, 95%CI 16.7-22.9) as compared to older patients (26.1, 95%CI 24.2-28) (p = 0.001). Current smoking (OR 7.5; 95%CI 1.8-30; p = 0.004) and age at smoking initiation (OR 0.8 for every increasing year; 95%CI 0.7-0.9; p = 0.01) were significant and independent risk factors for diagnosis of EOPC. There were no differences regarding genetic syndromes and pancreatic cancer family history. EOCP presented less frequently with jaundice (16% vs 44%, p = 0.006) and had a higher rate of unresectable disease, albeit not significantly (84% vs 68%, p = 0.1). EOPC patients were more frequently fit for surgery or chemotherapy than their counterpart, resulting in similar stage-specific survival probability. CONCLUSION: EOPC seems related to active and early smoking but not to familial syndromes. Young patients display aggressive disease but not worse outcome.
