Abstract

Background: Members of the tumor necrosis factor (TNF) superfamily of ligands and their receptors (TNFR) are critical regulators of the adaptive immune system. A proliferation inducing ligand (APRIL) is a member of tumor necrosis factor superfamily. APRIL was identified via database mining in 1998 by Hahne, et al. APRIL allows tumor cells to proliferate at a reasonable rate even in low serum. APRIL is abundantly expressed in many tumor cells and tumor tissues. Increasing level of APRIL expression related to replacement of -Arg-Lys-Arg-Arg- motif by -Ala-Lys-Arg-Ala- between amino acids 101-104 and thus abrogated APRIL processing. Previous studies have shown a correlation between APRIL expression with some autoimmune disease, breast cancer, stomach cancer, esophagus cancer and colorectal cancer. Herein, we explore correlation between serum APRIL with pancreatic cancer.

Methods: Our study is performed in digestive disease research institute (DDRI) of the Shariati Hospital in Tehran City and affiliated Hospital of Tehran University of Medical Sciences. In this study, concentrations of serum APRIL in sera (30 pancreatic cancer patients and 30 healthy controls) from November 2011 to November 2013 collected and level of a proliferation inducing ligand measured by ELISA technique. In this study used from SPSS software, version 22 (IBM SPSS, Armonk, NY, USA) to perform statistical data analysis.

Results: The case group measurement results compared with control groups results according to some characteristics such as age, smoking and, diabetes. ELISA analysis of APRIL measurements show that mean serum APRIL level of pancreatic cancer patients (7 ng/ml) was significantly higher than control group (5 ng/ml). The p-value of this study was 0.003.

Conclusion: Our results indicate that serum APRIL, as a potential biomarker, has a positive diagnosis and prognosis value for pancreatic cancer.

A review of the etiology and biomarkers of pancreatic cancer, with emphasis on the role of diabetes: review article

Abstract
Cancer is the major cause of death in the world and the rate of mortality is higher in developed countries. Therefore, lifestyle could be effective in promoting the cancer. The pancreatic tumors, are 8th cause of mortality due to cancer, which have several types, among them ductal adenocarcinoma is the most common and includes 85% of cases. Since, it is almost impossible to diagnosis the tumor in early stages of the disease, it contributes to high rates of mortality, although if it diagnosis in early stage and the surgery performed for them only 10-20% of patients will be survived. Metastasis occurs when the tumor is smaller than 2 cm in size and because the pancreas is located in the depth of abdomen, typically, it happens after tumor is spread to other organs. A combination of medical imaging, blood tests, and examination of tissue samples are usually made for diagnosis and based on the cancer stage, surgery, radiotherapy and chemotherapy are chosen as treatment options. Some rare genetic variations can cause pancreatic cancer and about 5-10% of cases are linked to inherited genes. However, major risk factors are including age, obesity, tobacco smoking and diabetes. Smoking counts for about 25% of cases, and the diabetes is the main symptoms of pancreatic cancer, which observed in about 80% of cases. But, it is still unclear whether diabetes is a predisposing factor in pancreatic cancer, or the outcome of tumor progression. Recent studies have shown that, diabetes is unique in pancreatic cancer which is not related to common types. Currently, CA 19-9 is the only reliable tumor marker for pancreatic cancer that its frequency also increases in non-bad conditions, such as pancreatitis and obstructive jaundice, so is not sensitive and specific enough for diagnosis of this cancer. Due to researches continue to find more specific markers. In this review the etiology of pancreatic cancer, diabetes associated with this type of cancer and significant biomarkers for diagnosis will be considered.

Abstract
Background: Among all types of cancers, pancreatic cancer has poor prognosis with 5-year survival below 10%. In theory, alcohol intake may be a modifiable risk factor for pancreatic cancer due to its role in multiple carcinogenic and metabolic signaling pathways. In addition, alcohol consumption may lead to chronic pancreatitis which is underlying cause of pancreatic cancer. However, little is known about whether this factor is associated with pancreatic cancer. This study aimed to systematically review the cohort studies investigating the possible link between alcohol consumption and the morbidity or mortality of pancreatic cancer.
Methods: This study was carried out based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). All of cohort studies that assessed the association between alcohol intake and the risk of pancreatic cancer or death were included in this systematic review without a language restriction. Electronic databases including PubMed, Web of science, Scopus, and Google scholar were searched using the keywords "pancreatic cancer" and "alcohol" and similar words from 1990 to April 2021 to find the cohort studies.
Results: 858 articles were identified, of which 806 were excluded and the full-text of 52 papers were evaluated for the eligibility. Eventually, 22 articles were eligible and were included in this study. Many of the articles assessed the impacts of low to moderate alcohol intake. A comprehensive review of these studies showed that low to moderate alcohol consumption had a non-significant correlation with pancreatic cancer, while high alcohol consumption was significantly associated with the risk of pancreatic cancer or death. The results also revealed that high liquor consumption was associated with higher risk of pancreatic cancer. Nevertheless, the follow-up durations in most of these studies were shorter than that to lead to pancreatic cancer.
Conclusion: Long-term heavy alcohol drinking can increase the morbidity or mortality of pancreatic cancer. Regarding that several genetic and environmental variations involve in the pathogenesis of this cancer, simultaneous control of these differences should be addressed to determine the net effect of alcohol drinking on pancreatic cancer.
