OBJECTIVES: To assess factors associated with radical resection (R0) of pancreatic ductal adenocarcinoma (PDAC) after induction treatment with FOLFIRINOX. METHODS: Patients with either locally advanced (LA) and borderline resectable (BR) PDAC undergoing surgical exploration after FOLFIRINOX were retrospectively enrolled. Two pancreatic radiologists reviewed the CT blinded to the final outcome and assessed chemotherapy response and resectability. Patients were then divided into R0 resected (group A) and not resected/R1 resected (group B), which were compared...

Non-functional pancreatic neuroendocrine tumours (NETs) can present with advanced local or distant (metastatic) disease limiting the possibility of surgical cure. Several treatment options have been used in experimental neoadjuvant settings to improve the outcomes in such cases. Peptide receptor radionuclide therapy (PPRT) using beta emitting radiolabelled somatostatin analogues has been used in progressive pancreatic NETs. We report a 55-year-old female patient with a 12.8 cm pancreatic NET with significant local stomach and superior mesenteric vein compression and liver metastases...

Neuropeptide Y (NPY) receptors belong to the G-protein-coupled receptor superfamily and have important roles in food intake, anxiety and cancer biology 1,2 . The NPY-Y receptor system has emerged as one of the most complex networks with three peptide ligands (NPY, peptide YY and pancreatic polypeptide) binding to four receptors in most mammals, namely the Y1 , Y2 , Y4 and Y5 receptors, with different affinity and selectivity 3 . NPY is the most powerful stimulant of food intake and this effect is primarily mediated by the Y1 receptor (Y1 R) 4 ...

Herein, we describe the synthesis of twenty-one novel water-soluble monocationic 2-aryl/heteroaryl-substituted 6-(2-imidazolinyl)benzothiazole mesylates 3a-3u and present the results of their anti-proliferative assays. Efficient syntheses were achieved by three complementary simple two-step synthetic protocols based on the condensation reaction of aryl/heteroaryl carbaldehydes or carboxylic acid. We developed an eco-friendly synthetic protocol using glycerol as green solvent, particularly appropriate for the condensation of thermally and acid-sensitive heterocycles such as furan, benzofuran, pyrrole, and indole...

Pancreatic cancer remains one of the most lethal forms of cancer with a 10-year survival of <1%. With little improvement in survival rates observed in the past 40 years, there is a significant need for new treatments or more effective strategies to deliver existing treatments. The antimetabolite gemcitabine (Gem) is the most widely used form of chemotherapy for pancreatic cancer treatment, but is known to produce significant side effects when administered systemically. We have previously demonstrated the benefit of combined chemo-sonodynamic therapy (SDT), delivered using oxygen carrying microbubbles (O2 MB), as a targeted treatment for pancreatic cancer in a murine model of the disease...

Pancreatic neuroendocrine tumours (PNETs) are rare. They are generally accepted to be slow-growing and have an indolent course. These tumours can be non-functioning or functioning, consisting of a biochemically heterogeneous group of tumours including insulinomas, gastrinomas, carcinoids and glucagonomas. Although surgery remains the mainstay of treatment, controversy still exists especially for non-functioning tumours <2 cm in size. Whether these should be resected or undergo intensive surveillance remains unclear...

The intravoxel incoherent motion (IVIM) model for diffusion-weighted imaging (DWI) MRI data bears much promise as a tool for visualizing tumours and monitoring treatment response. To improve the currently poor precision of IVIM, several fit algorithms have been suggested. In this work, we compared the performance of two Bayesian IVIM fit algorithms and four other IVIM fit algorithms for pancreatic cancer imaging. DWI data were acquired in 14 pancreatic cancer patients during two MRI examinations. Three different measures of performance of the fitting algorithms were assessed: (i) uniqueness of fit parameters (Spearman's rho); (ii) precision (within-subject coefficient of variation, wCV); and (iii) contrast between tumour and normal-appearing pancreatic tissue...

Surgery for the treatment of pancreatic cancer remains the gold standard, however, the identification of the vascular supply of the pancreas and the nearby organs remains a crucial difficulties in a curative resection. During pancreatic head resection for carcinoma dissection of regional arterial vasculature is mandatory. Normal coeliac and hepatic arterial anatomy occurs in ~50-70% of patients and multiple variations have been described. Knowledge of multiple arterial anomalies is essential in hepato-pancreatico-billary surgery to avoid unnecessary complications...

AIMS: External beam radiotherapy (EBRT) is infrequently used to treat gastroenteropancreatic neuroendocrine tumours (GEPNETS), with little published data to date. We carried out a systematic review to assess the activity of EBRT for GEPNETS. MATERIALS AND METHODS: Major databases were searched for papers including at least five patients treated with contemporary EBRT techniques. Eligible studies underwent dual independent review. The primary end points were response rate for lesions treated with definitive intent and recurrence-free survival for primary lesions treated with neoadjuvant or adjuvant intent...

AIMS: Gastrointestinal toxicity impedes dose escalation in chemoradiotherapy for hepatobiliary malignancies. Toxicity risk depends on clinical and radiotherapy metrics. We aimed to identify predictive factors using data from two prospective phase II clinical trials of locally advanced pancreatic cancer (LAPC). MATERIALS AND METHODS: Ninety-one patients with available data from the ARCII (59.4 Gy in 33 fractions with gemcitabine, cisplatin and nelfinavir, n = 23) and SCALOP (50...

BACKGROUND/AIM: The role of histone demethylators, such as Jumonji domain 2 (JMJD2/KDM4) proteins, and histone deacetylases, such as sirtuins (SIRT) is poorly characterized in pancreatic carcinomas while they have a major role in the carcinogenesis of several other tumours. MATERIALS AND METHODS: We assessed retrospectively with immunohistochemistry the expressions of KDM4A, KDM4B and KDM4D in 81 and SIRT1-4 in 102 pancreatic adenocarcinomas. Immunostaining was evaluated separately in benign pancreatic tissues and in malignant cells...

Background: Von Hippel-Lindau (VHL) disease may occur at various localisations which can be both intra- and extrapancreatic as well as challenging to diagnose by medical imaging. Case Report: A positron emission tomography/magnetic resonance imaging in a 40-year-old woman was performed to monitor a haemangioblastoma. Additionally, it showed findings which were considered to be a pancreatic neuroendocrine tumour (pNET) and retroumbilical metastasis. The suspected metastasis was laparoscopically resected; however, pathological evaluation did not lead to a clear categorisation...

BACKGROUND: Pancreatic ductal adenocarcinoma is one of the most lethal types of cancer with a 5-year survival rate of around 7%. Due to the relatively poor prognosis, the potential need of an effective chemoprevention is highly needed. SUMMARY: Different risk factors like smoking or hereditary tumour syndromes should be known for early detection of pancreatic intraepithelial neoplasia. Chemopreventive dietary agents include curcumin, capsaicin and flavonoid, whereas potential chemopreventive drugs compromise aspirin, metformin or statins...

Evidence-based guidelines on the management of pancreatic cystic neoplasms (PCN) are lacking. This guideline is a joint initiative of the European Study Group on Cystic Tumours of the Pancreas, United European Gastroenterology, European Pancreatic Club, European-African Hepato-Pancreato-Biliary Association, European Digestive Surgery, and the European Society of Gastrointestinal Endoscopy. It replaces the 2013 European consensus statement guidelines on PCN. European and non-European experts performed systematic reviews and used GRADE methodology to answer relevant clinical questions on nine topics (biomarkers, radiology, endoscopy, intraductal papillary mucinous neoplasm (IPMN), mucinous cystic neoplasm (MCN), serous cystic neoplasm, rare cysts, (neo)adjuvant treatment, and pathology)...

<br>Introduction The gastrointestinal tract and pancreas are common primary sites for neuroendocrine tumours (NETs). Patients often report long duration of non-specific symptoms in the year prior to diagnosis. The aims of this study were to establish pre-diagnosis patterns of symptoms. Secondly, to determine the time from onset of symptoms to NET diagnosis and understand the interaction with primary and secondary healthcare providers. Method A survey was designed on a web-based survey platform with the focus on patient symptoms prior to diagnosis and a screen for functional diarrhoea (Rome III criteria (C4))...

Early detection of malignant tumours and, especially, micrometastases and disseminated tumour cells is still a challenge. In order to implement highly sensitive diagnostic tools we demonstrate the use of nanoprobes engineered from nanobodies (single-domain antibodies, sdAbs) and fluorescent quantum dots (QDs) for single- and two-photon detection and imaging of human micrometastases and disseminated tumour cells in ex vivo biological samples of breast and pancreatic metastatic tumour mouse models expressing human epidermal growth factor receptor 2 (HER2) or carcinoembryonic antigen (CEA)...
