Abstract
Pancreatic cancer is characterized by extremely high mortality and poor prognosis and is projected to be the leading cause of cancer deaths by 2030. Due to the lack of early symptoms and appropriate methods to detect pancreatic carcinoma at an early stage as well as its aggressive progression, the disease is often quite advanced by the time a definite diagnosis is established. The 5-year relative survival rate for all stages is approximately 8%. Therefore, detection of pancreatic cancer at an early surgically resectable stage is the key to decrease mortality and to improve survival. The traditional methods for diagnosing pancreatic cancer involve an imaging test, such as ultrasound or magnetic resonance imaging, paired with a biopsy of the mass in question. These methods are often expensive, time consuming, and require trained professionals to use the instruments and analyze the imaging. To overcome these issues, biosensors have been proposed as a promising tool for the early diagnosis of pancreatic cancer. The present review critically discusses the latest developments in biosensors for the early diagnosis of pancreatic cancer. Protein and microRNA biomarkers of pancreatic cancer and corresponding biosensors for pancreatic cancer diagnosis have been reviewed, and all these cases demonstrate that the emerging biosensors are becoming an increasingly relevant alternative to traditional techniques. In addition, we discuss the existing problems in biosensors and future challenges.

[New progress in the treatment of locally advance pancreatic cancer].
de Santibañes, M, Sanchez Clariá, R, de Santibañes, E, Pekolj, J, Mazza, O
Medicina. 2019;(Spec 6/1):576-581
Abstract
Locally advanced pancreatic cancer (LAPC) has several definitions, but it is essentially a non-metastatic tumor, in which the initial surgical resection is not considered beneficial due to the extensive vascular involvement and consequent high chance of a nonradical resection. The introduction of chemotherapy with calcium leucovorin, fluorouracil, irinotecan hydrochloride and oxaliplatin (FOLFIRINOX) and gemcitabine-nab (nanoparticle albumin-bound)-paclitaxel (gem-nab) had very important implications for the management of patients with LAPC. After 4 to 6 months of induction chemotherapy, a large proportion of them have stable disease or even tumor regression, allowing to rescue those who initially were not candidates for surgery, with 30-35 months overall survival after surgery.

Abstract
Owing to the location of the pancreas and its complex anatomical relationship, it is difficult to perform radioactive Iodine-125 seed implantation in patients with pancreatic cancer as it can cause surgical side effects and further complications. To standardize the procedure of radioactive Iodine-125 seed implantation in the treatment of pancreatic cancer and reduce the occurrence of adverse reactions and complications during and after operation, the Chinese Medical Doctor Association of Radioactive Seed Implantation Technology Expert Committee, Committee of Minimally Invasive Therapy in Oncology, Chinese Anti-Cancer Association, and the Radioactive Seed Therapy Branch organized and helped establish an expert consensus in China regarding radioactive Iodine-125 seed implantation in the treatment of pancreatic cancer. This article aims at interpreting the adverse reactions and complications after the implantation of radioactive seeds.

Endoscopic diagnosis of pancreatic cysts.
Blaszczak, AM, Krishna, SG
Current opinion in gastroenterology. 2019;(5):448-454
Abstract
PURPOSE OF REVIEW Pancreatic cystic lesions (PCLs) are increasingly identified on abdominal imaging. Given the malignant potential of certain cyst subtypes and the poor survival rates of pancreatic cancer, accurate diagnosis and appropriate management of these cysts are critical. RECENT FINDINGS Advances in endoscopic ultrasound (EUS)-guided diagnostics have increased the accuracy of differentiating PCLs. These include cyst fluid molecular analysis, EUS-guided needle-based confocal laser endomicroscopy, and EUS-guided through the needle microforceps biopsy. This review encapsulates recent advances in the endoscopic management of PCLs with a specific focus on EUS-guided diagnosis. SUMMARY It is important to accurately diagnose pancreatic cystic lesions with malignant potential where the definitive management is surgical resection. Misdiagnosis can result in inadvertent surgery of an otherwise benign lesion or malignant progression of a precancerous cyst. Moreover, pancreatic surgery is associated with significant morbidity and mortality. Recent advances in EUS-guided tissue acquisition, imaging, and molecular biomarkers have resulted in improved diagnostic accuracy of pancreatic cystic lesions. Future studies need to define efficient and accurate diagnostic algorithms for improved management of pancreatic cysts.

Abstract
Unintentional weight loss in patients with pancreatic cancer is highly prevalent and contributes to low therapeutic tolerance, reduced quality of life, and overall mortality. Weight loss in pancreatic cancer can be due to anorexia, malabsorption, and/or cachexia. Proper supportive care can stabilize or reverse weight loss in patients and improve outcomes. We review the literature on supportive care relevant to pancreatic cancer patients, and offer evidence-based recommendations that include expert nutritional assessment, counseling, supportive measures to ensure adequate caloric intake, pancreatic enzyme supplementation, nutritional supplement replacement, orexigenic agents, and exercise. Pancreatic Cancer Action Network-supported initiatives will spearhead the dissemination and adoption of these best supportive care practices. IMPLICATIONS FOR PRACTICE Weight loss in pancreatic cancer patients is endemic, as 85% of pancreatic cancer patients meet the classic definition of cancer cachexia. Despite its significant prevalence and associated morbidity, there is no established approach to this disease entity. It is believed that this is due to an important knowledge gap in understanding the underlying biology and lack of optimal treatment approaches. This article reviews the literature regarding pancreas cancer-associated weight loss and establishes a new framework from which to view this complex clinical problem. An improved approach and understanding will help educate clinicians, improve clinical care, and provide more clarity for future clinical investigation.

Diabetes and pancreatic neuroendocrine tumours: Which interplays, if any?
Gallo, M, Ruggeri, RM, Muscogiuri, G, Pizza, G, Faggiano, A, Colao, A, ,
Cancer treatment reviews. 2018;:1-9
Abstract
Pancreatic neuroendocrine tumours (PanNETs) represent an uncommon type of pancreatic neoplasm, whose incidence is increasing worldwide. As per exocrine pancreatic cancer, a relationship seems to exist between PanNETs and glycaemic alterations. Diabetes mellitus (DM) or impaired glucose tolerance often occurs in PanNET patients as a consequence of hormonal hypersecretion by the tumour, specifically affecting glucose metabolism, or due to tumour mass effects. On the other hand, pre-existing DM may represent a risk factor for developing PanNETs and is likely to worsen the prognosis of such patients. Moreover, the surgical and/or pharmacological treatment of the tumour itself may impair glucose tolerance, as well as antidiabetic therapies may impact tumour behaviour and patients outcome. Differently from exocrine pancreatic tumours, few data are available for PanNETs as yet on this issue. In the present review, the bidirectional association between glycaemic disorders and PanNETs has been extensively examined, since the co-existence of both diseases in the same individual represents a further challenge for the clinical management of PanNETs.

Pancreatic cancer: A critical review of dietary risk.
Salem, AA, Mackenzie, GG
Nutrition research (New York, N.Y.). 2018;:1-13
Abstract
Pancreatic cancer is a deadly disease. It is estimated that about 90% of pancreatic cancer cases are due to environmental risk factors. Among these, approximately 50% of pancreatic cancer cases may be attributed to diet, which is largely modifiable. Given this large attribution to diet, there have been numerous epidemiological studies assessing the risk of various dietary factors on the incidence of pancreatic cancer. However, many of these studies present conflicting and/or inconclusive findings. The objective of this review is two-fold: (a) to summarize the current evidence on the association between various dietary factors and the risk of developing pancreatic cancer and (b) to discuss what additional studies are needed to better elucidate the role of diet as a potential risk factor for pancreatic cancer. We summarized the evidence by using data primarily from meta-analyses and pooled analysis when available, focusing on the most studied nutrients, foods, and dietary patterns. We observed that, while the association between individual nutrients and pancreatic cancer risk have been heavily studied, the evidence is mostly conflicting and inconclusive. In contrast, the evidence of certain associations among dietary patterns and pancreatic cancer risk is clearer, has more power, and is less conflicting. Therefore, we propose a shift in the focus of nutritional epidemiological research with regards to pancreatic cancer risk. We discourage further epidemiological research studies that focus on single nutrients, whereas we strongly encourage additional studies that investigate how a combination of diet and other lifestyle factors may promote or prevent pancreatic carcinogenesis.

Is endoscopic ultrasonography more sensitive than magnetic resonance imaging in detecting and localizing pancreatic neuroendocrine tumors?
Kann, PH
Reviews in endocrine & metabolic disorders. 2018;(2):133-137
Abstract
To compare endoscopic ultrasonography (EUS) and magnetic resonance imaging (MRI) in terms of their sensitivities to localize pancreatic neuroendocrine tumors (pNET) preoperatively. Systematic analysis of the literature; sensitivity of EUS and MRI in insulinomas and pancreaticoduodenal NETs in multiple endocrine neoplasia type 1 (MEN1) in series of at least 20 subjects referring to tumors confirmed by surgery and histopathology. Other imaging methods reported were also assessed. Eighteen publications on insulinomas (782 cases) could be analyzed, no study in MEN1 fulfilled the inclusion criteria and compared EUS to MRI. Data quality was moderate: all publications referred to case series. Mean correct detection / localization rates (sensitivity) were calculated: EUS 80%, MRI 66%, computed tomography 63%, angiography 52%, somatostatin receptor scintigraphy 42%, ultrasonography 23%; arterial calcium stimulation with hepatic venous sampling regionalized correctly in 80%. EUS seems to be more sensitive than MRI in localizing pancreatic neuroendocrine tumors. If a specialized endosonographist is available, EUS is the preferable imaging procedure. Otherwise, MRI is a suitable alternative.

Supportive therapy in gastroenteropancreatic neuroendocrine tumors: Often forgotten but important.
Jin, XF, Spampatti, MP, Spitzweg, C, Auernhammer, CJ
Reviews in endocrine & metabolic disorders. 2018;(2):145-158
Abstract
Neuroendocrine tumors (NETs) are a group of rare and heterogeneous malignancies that can develop in various organs. A significant number of gastroenteropancreatic neuroendocrine tumours (GEP-NETs) is functionally active and presents with symptoms related to the secretion of biologically active substances, leading to the development of distinct clinical syndromes. There are various therapeutic approaches for GEP-NETs, including curative surgery, palliative surgery, local-ablative and loco-regional therapies as well as systemic therapeutic options including peptide receptor radionuclide therapy, cytotoxic therapy, and molecularly targeted therapies. Specific supportive therapy of patients with NETs includes management or prevention of hormone-related clinical syndromes and paraneoplastic states. Supportive therapy plays a key role in NET treatment. Supportive therapy includes debulking surgery and interventional radiologic techniques to reduce tumour bulk or load, as well as systemic medical treatment options to manage or prevent hypersecretion syndromes and treatment-related side effects. Supportive therapies are a type of of comprehensive treatment addressing the patient as a whole person throughout the process of NET treatment. Therefore, supportive therapy also encompasses psychosocial support, expert nursing, nutritional support and management of cancer related pain.
