Br J Cancer 2022; 127:549-557. [PMID: 35444288 PMCID: PMC9345883 DOI: 10.1038/s41416-022-01807-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2021] [Revised: 03/21/2022] [Accepted: 03/25/2022] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND Large-scale epidemiological studies on pancreatic cancer in non-Western populations are insufficient. We investigated the risk factors for pancreatic cancer. METHODS Using the Korean National Health Insurance database, subjects who participated in the health examination program between 2005 and 2006 were identified and followed up until 2017. Adjusted hazard ratios (HRs) for pancreatic cancer risk were estimated using a Cox proportional hazards model. RESULTS During 11.5 years follow-up, 22,543 of 7,445,947 participants were newly diagnosed with pancreatic cancer. Compared with normal-weight subjects, pancreatic cancer risk was increased in those with severe obesity (BMI ≥ 28 kg/m2) (HR = 1.16; 95% CI, 1.11-1.23). Subjects with diabetes had an increased risk compared with those without diabetes (HR = 1.48; 95% CI, 1.43-1.53). Current smokers had a higher risk than never smokers (HR = 1.43; 95% CI, 1.38-1.48). Current smoking combined with diabetes increased the risk compared with never smokers without diabetes (HR = 2.13; 95% CI, 2.00-2.28). Current smoking combined with BMI ≥ 25 kg/m2 had an increased risk compared with never smokers with BMI < 23 kg/m2 (HR = 1.55; 95% CI, 1.46-1.65). CONCLUSION Smoking, obesity, and diabetes are significant risk factors for pancreatic cancer in Koreans. Lifestyle modifications for smoking and obesity would be beneficial for pancreatic cancer prevention.

Abstract
Pancreatic cancer is becoming an increasing healthcare concern. Though it is a 14th most common cancer worldwide, its incidence is steadily rising. Results of currently available therapies are still not satisfactory. Therefore, great attention should be put on the identification and reduction of risk factors for pancreatic cancer. A thorough up-to-date review of available data on the impact of well-established and novel risk factors of pancreatic cancer development have been performed. Several risk factors associated with lifestyle have significant impact on the risk of pancreatic cancer (i.e., smoking, obesity, alcohol consumption). Physicians should also be aware of the novel findings suggesting increasing role of microbiome, including viral and bacterial infections, in the development of pancreatic cancer. A growing body of evidence suggest also an increased risk during certain occupational exposures. In general, lifestyle seems to be a major contributor in the development of pancreatic cancer. Special attention should be given to individuals with a vicious cluster consisting of metabolic syndrome, tobacco smoking and alcohol consumption. Physicians should urge patients to comply to healthy diet, cessation of smoking and moderation of alcohol consumption, which may halve pancreatic cancer incidence. Further studies are warranted to explore the potential use of therapeutic approach on novel risk factors (e.g., microbiome).

Abstract
BACKGROUND Gastroenteropancreatic neuroendocrine neoplasms [GEP-NENs] have rarely been reported in association with inflammatory bowel diseases [IBDs]. METHODS An ECCO COllaborative Network For Exceptionally Rare case reports project [ECCO-CONFER] collects cases of GEP-NENs diagnosed in patients with IBD. RESULTS GEP-NEN was diagnosed in 100 IBD patients; 61% female, 55% Crohn's disease, median age 48 years (interquartile range [IQR] 38-59]). The most common location was the appendix [39%] followed by the colon [22%]. Comprehensive IBD-related data were available for 50 individuals with a median follow-up of 30 months [IQR 11-70] following NEN diagnosis. Median duration of IBD at NEN diagnosis was 84 months [IQR 10-151], and in 18% of cases NEN and IBD were diagnosed concomitantly. At diagnosis, 20/50 were stage-I [T1N0M0], and 28/50 were graded G1 [ki67 ≤2%]. Incidental diagnosis of NEN and concomitantly IBD diagnosis were associated with an earlier NEN stage [p = 0.01 and p = 0.02, respectively]. Exposure to immunomodulatory or biologic therapy was not associated with advanced NEN stage or grade. Primary GEP-NEN were more frequently found in the segment affected by IBD [62% vs 38%]. At the last follow-up data, 47/50 patients were alive, and only two deaths were related to NEN. CONCLUSIONS In the largest case series to date, prognosis of patients with GEP-NEN and IBD seems favourable. Incidental NEN diagnosis correlates with an earlier NEN stage, and IBD-related therapies are probably independent of NEN stage and grade. The association of GEP-NEN location and the segment affected by IBD may suggest a possible role of inflammation in NEN tumorigenesis.

Abstract
BACKGROUND Pancreatic cancer presents as advanced disease in >80% of patients; yet, appropriate ages to consider prevention and early detection strategies are poorly defined. We investigated age-specific associations and attributable risks of pancreatic cancer for established modifiable and non-modifiable risk factors. PATIENTS AND METHODS We included 167 483 participants from two prospective US cohort studies with 1190 incident cases of pancreatic cancer during >30 years of follow-up; 5107 pancreatic cancer cases and 8845 control participants of European ancestry from a completed multicenter genome-wide association study (GWAS); and 248 893 pancreatic cancer cases documented in the US Surveillance, Epidemiology, and End Results (SEER) Program. Across different age categories, we investigated cigarette smoking, obesity, diabetes, height, and non-O blood group in the prospective cohorts; weighted polygenic risk score of 22 previously identified single nucleotide polymorphisms in the GWAS; and male sex and black race in the SEER Program. RESULTS In the prospective cohorts, all five risk factors were more strongly associated with pancreatic cancer risk among younger participants, with associations attenuated among those aged >70 years. The hazard ratios comparing participants with three to five risk factors with those with no risk factors were 9.24 [95% confidence interval (CI) 4.11-20.77] among those aged ≤60 years, 3.00 (95% CI 1.85-4.86) among those aged 61-70 years, and 1.46 (95% CI 1.10-1.94) among those aged >70 years (Pheterogeneity = 3×10-5). These factors together were related to 65.6%, 49.7%, and 17.2% of incident pancreatic cancers in these age groups, respectively. In the GWAS and the SEER Program, the associations with the polygenic risk score, male sex, and black race were all stronger among younger individuals (Pheterogeneity ≤0.01). CONCLUSIONS Established risk factors are more strongly associated with earlier-onset pancreatic cancer, emphasizing the importance of age at initiation for cancer prevention and control programs targeting this highly lethal malignancy.

Abstract
BACKGROUND Poultry plant workers are exposed to chemical carcinogens and oncogenic viruses in their work environment. Our objective was to identify jobs and workplaces related to poultries that could increase the pancreatic cancer risk. METHODS We conducted a case-control study within a defined cohort of poultry workers. We used a random forest algorithm to identify features that could increase pancreatic cancer in the poultry plant workers. RESULTS The mean age of participants was 59.49 years. The majority of the study participants were females (51.30%) and Whites (71.0%). The following workplaces and job tasks had an association with increased pancreatic cancer mortality: working in chicken and turkey plants, working in plants where food products were processed and canned, working in a place where poultry and animals where present, working as a hunter for game animals, working as a veterinarian in places had animals and different poultry birds, working in pet houses and working in places where birds were handled and killed. The accuracy and the area under the curve of the model were 72.3 and 71.50%. CONCLUSION Chicken and turkey plant workers could be at risk for pancreatic cancer mortality. We need to confirm the results in future studies.

Abstract
BACKGROUND Different surveillance strategies for patients with low-risk branch-duct (BD) intraductal papillary neoplasm (IPMN) have been described. The aim of this study was to describe the natural history of low-risk BD-IPMN, and to identify risk factors for the development of worrisome features (WF)/high-risk stigmata (HRS) and of pancreatic malignancies. METHODS This was a multicentre retrospective study of patients with BD-IPMN who were under active surveillance between January 2006 and December 2015. Patients were eligible if they had a low-risk lesion and had a minimum follow-up of 24 months. Outcomes were development of WF/HRS or cytologically/histologically confirmed malignant IPMN. RESULTS Of 837 patients included, 168 (20 per cent) developed WF/HRS. At the end of the observation time, 132 patients (79 per cent) with WF/HRS were still under surveillance without progression to pancreatic cancer. Factors associated with the development of WF or HRS in multivariable analysis included localized nodules (versus diffuse: hazard ratio (HR) 0.43, 95 per cent c.i. 0.26 to 0.68), cyst size 15-19 mm (versus less than 15 mm: HR 1.88, 1.23 to 2.87) or at least 20 mm (versus less than 15 mm: HR 3.25, 2.30 to 4.60), main pancreatic duct size over 3 mm (versus 3 mm or less: HR 2.17, 1.41 to 3.34), and symptoms at diagnosis (versus no symptoms: HR 2.29, 1.52 to 3.45). Surveillance in an endoscopy-oriented centre was also associated with increased detection of WF or HRS (versus radiology-oriented: HR 2.46, 1.74 to 3.47). CONCLUSION Conservative management of patients with low-risk BD-IPMN is safe and feasible.

Abstract
Pancreatic cancer is a deadly disease that is increasing in incidence throughout the world. There are no clear causal factors associated with the incidence of pancreatic cancer; however, some correlation to smoking, diabetes and alcohol has been described. Recently, a few studies have linked the human microbiome (oral and gastrointestinal tract) to pancreatic cancer development. A perturbed microbiome has been shown to alter normal cells while promoting cancer-related processes such as increased cell signaling, immune system evasion and invasion. In this article, we will review in detail the alterations within the gut and oral microbiome that have been linked to pancreatic cancer and explore the ability of other microbiomes, such as the lung and skin microbiome, to contribute to disease development. Understanding ways to identify a perturbed microbiome can result in advancements in pancreatic cancer research and allow for prevention, earlier detection and alternative treatment strategies for patients.

Abstract
PURPOSE Lifestyle factors such as smoking, alcohol, body weight, physical activity, and diet quality have been associated with the risk of pancreatic cancer. However, studies of their combined association in women are limited. METHODS Data on smoking habits, alcohol intake, diet composition, recreational physical activity, body weight, and waist circumference, obtained at recruitment for 136,945 postmenopausal women (aged 50-79 years) participating in the Women's Health Initiative study, were categorized separately, with higher scores for each variable assigned to the categories representing healthier behaviors. The combined healthy lifestyle index (HLI) score, created by summing the scores for each risk factor, was grouped into quartiles. We used multivariable-adjusted Cox regression to estimate hazard ratios (HR) and 95% confidence intervals (CI) for pancreatic cancer risk in association with the HLI. RESULTS Over an average follow-up period of approximately 16.0 years, 1,119 incident cases of pancreatic cancer were ascertained. Compared to women in the lowest HLI quartile, those in the upper quartiles (qt) had a reduced risk of pancreatic cancer (multivariable-adjusted HRqt3rd 0.83, 95% CI 0.74-0.99; and HRqt4th 0.74, 95% CI 0.62-0.88, respectively, p trend = 0.001). Use of waist circumference instead of BMI in the HLI score yielded similar results. Among women who were either non-diabetic or non-smokers, high HLI was also associated with reduced risk (HRqt4th 0.78, 95% CI 0.65-0.85 and HRqt4th 0.80, 95% CI 0.66-0.97, respectively). Stratification by BMI categories (18.5- < 25.0, 25.0- < 30.0 and > 30.0 kg/m2) showed similar results in all groups. CONCLUSIONS Our findings suggest that in postmenopausal women, a healthy lifestyle is associated with reduced risk of pancreatic cancer.

Abstract
BACKGROUND AND AIMS The purpose of this study was to assess prognosis with different intratumoral vascularity on contrast-enhanced endoscopic harmonic ultrasonography (CH-EUS) in pancreatic cancer patients receiving chemotherapy. METHODS Patients with unresectable pancreatic cancer who underwent CH-EUS before first-line gemcitabine and nab-paclitaxel (GEM and nab-PTX) therapy were classified into four groups according to vascularity on the early and late phases of contrast enhancement: "Group A″, poor on both phases; "Group B″, rich and poor on the early and late phases, respectively; "Group C″, poor and rich on the early and late phases; "Group D″, rich on both phases. Subgroups were compared in terms of progression-free survival (PFS) and overall survival (OS). We also assessed whether the results with CH-EUS correlate with those of contrast-enhanced computed tomography (CE-CT). RESULTS On CH-EUS, 57, 64, 0, and 24 patients were classified into Groups A, B, C, and D, respectively. The median PFS of patients in groups A, B, and D was 3.9, 7.6, and 10.8 months, respectively, and the median OS were 9.5, 13.1, and 18.6 months, respectively. Both PFS and OS were longest in Group D (p < 0.001 and p < 0.001, respectively). The results of CE-CT were consistent with those of CH-EUS, and there was a correlation between CE-CT and CH-EUS. CONCLUSIONS Evaluation of intratumoral vascularity by CH-EUS may be useful for predicting the efficacy of chemotherapy in patients with pancreatic cancer. A better response to GEM and nab-PTX can be expected in patients showing rich vascularity at both the early and late phases.

Abstract
Research from epidemiologic studies and experimental animal models provide insights into the role of pancreatic steatosis in the development of pancreatic cancer. Epidemiologic data demonstrate that pancreatic steatosis is widely prevalent and significantly associated with both development and progression of pancreatic cancer. By focusing on current experimental models, this review elucidates potential cellular mechanisms underlying not only the pathophysiology of pancreatic steatosis itself, but also the pathogenesis behind pancreatic steatosis's role in changing the tumour microenvironment and accelerating the development of pancreatic cancer. This review further explores the impact of bariatric surgery on pancreatic steatosis and pancreatic cancer. Synthesizing knowledge from both epidemiologic studies and experimental animal models, this review identifies gaps in current knowledge regarding pancreatic steatosis and its role in carcinogenesis and proposes future research directions to elucidate the possible mechanisms underlying other obesity-associated cancers.

Abstract
Many studies have been published to assess the association about dietary protein intake on the risk of pancreatic cancer, but with inconsistent result. This meta-analysis aimed to evaluate whether protein intake could affect the risk of pancreatic cancer. A systematic literature search was performed in PubMed, EMBASE and Web of Science up to October 1, 2019. Pooled relative risks (RR) and 95% confidence intervals (CI) were calculated using a random-effect model. A total of 14 studies (12 case-control studies and two cohort studies) were included. Overall, total protein intake had no significant association on the risk of pancreatic cancer (RR = 1.02, 95%CI= 0.85-1.22, I2=45.7%). Subgroup analyses showed such relationships were almost not influenced by study design and geographic location. Interestingly, when we performed the subgroup analysis by protein type, the opposite association was found in animal protein intake (RR = 1.37, 95%CI= 0.93-2.01) and vegetable protein intake (RR = 0.78, 95%CI= 0.54-1.14), although these two groups were not statistically significant. In conclusion, this meta-analysis indicated that dietary total protein intake may be not associated with the risk of pancreatic cancer. However, protein type may be affecting the result which was found from our research. Therefore, studies with detailed information, especially protein type, are warranted to further confirm these findings.

Abstract
The intestinal microenvironment is composed of normal gut microbiota and the environment in which it lives. The largest microecosystem in the human body is the gut microbiota, which is closely related to various diseases of the human body. Pancreatic cancer (PC) is a common malignancy of the digestive system worldwide, and it has a 5-year survival rate of only 5%. Early diagnosis of pancreatic cancer is difficult, so most patients have missed their best opportunity for surgery at the time of diagnosis. However, the etiology is not entirely clear, but there are certain associations between PC and diet, lifestyle, obesity, diabetes and chronic pancreatitis. Many studies have shown that the translocation of the gut microbiota, microbiota dysbiosis, imbalance of the oral microbiota, the interference of normal metabolism function and toxic metabolite products are closely associated with the incidence of PC and influence its prognosis. Therefore, understanding the correlation between the gut microbiota and PC could aid the diagnosis and treatment of PC. Here, we review the correlation between the gut microbiota and PC and the research progresses for the gut microbiota in the diagnosis and treatment of PC.

Abstract
BACKGROUND Pancreatic cancer is a disease of the elderly; patients >65 years are 60% of the cases. Due to multiple comorbidities, treating these patients is challenging. We report the efficacy and safety of carbon ion radiotherapy (C-ion RT) in octogenarians. METHODS We retrospectively analyzed the cases of 46 pancreatic cancer patients aged ≥80 years (median 83, range 80-97) treated with definitive C-ion RT in 2007-2018 at our institute. RESULTS Twenty-five patients (54%) had resectable or borderline-resectable disease; none underwent surgery (because of medical reasons, e.g., age, multiple comorbidities). C-ion RT was delivered with a median dose of 55.2 Gy (RBE) in 12 fractions. The survivors' median follow-up period was 43 (range 19-76) months. The entire cohort's median overall survival (OS) was 15 (95%CI: 14-22) months with a 3-year OS of 20% (95%CI: 11%-35%). On both univariate and multivariate analyses, baseline CA19-9 remained the significant independent OS prognostic factor (p = 0.032). The 3-year local control rate for all patients was 34% (95%CI: 19%-53%). Local failure (n = 25, 54%) was as common as distant relapse (n = 26, 57%); 33% of the patients experienced both local and systemic failure. About 15% underwent re-C-ion RT for infield recurrence; they achieved a median 22-month OS. No patients exhibited grade ≥3 severe acute or late toxicities (including those who received re-C-ion RT). CONCLUSIONS C-ion RT in octogenarians with pancreatic cancer showed promising outcomes with acceptable acute and late toxicities and can be considered a reasonable alternative to radical surgery.

[PMID: 35142721 PMCID: PMC8963838 DOI: 10.14309/ctg.0000000000000463] [Citation(s) in RCA: 25] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Accepted: 12/15/2021] [Indexed: 12/28/2022] Open
Abstract
INTRODUCTION Observational studies have suggested an increased risk of pancreatic ductal adenocarcinoma (PDAC) in patients with acute and chronic pancreatitis. We conducted a systematic review and meta-analysis to evaluate the magnitude of this association and summarize the published epidemiological evidence. METHODS We searched electronic databases (MEDLINE, Embase, Web of Science, Cochrane, and Scopus) and reference lists until January 18, 2021. Studies reporting quantitative association between pancreatitis and PDAC were included and assessed for eligibility, data abstraction, and risk of bias. Standardized incidence ratios (SIRs) were pooled using the random-effects model. RESULTS Twenty-five cohort and case-control studies met inclusion criteria. Meta-analysis of 12 chronic pancreatitis (CP) studies demonstrated an increased risk of PDAC in patients with CP (SIR: 22.61, 95% confidence interval [CI]: 14.42-35.44). This elevated risk persisted in subgroup analysis of studies that excluded patients diagnosed with PDAC within 2 years of CP diagnosis (SIR: 21.77, 95% CI: 14.43-32.720). The risk was higher in hereditary pancreatitis (SIR: 63.36, 95% CI: 45.39-88.46). The cumulative incidence rates of PDAC in CP increased with follow-up duration. Limited evidence in acute pancreatitis indicates higher PDAC risk in the subset of patients eventually diagnosed with CP. PDAC seems to be uncommon in patients with autoimmune pancreatitis, with 8 reported cases in 358 patients with autoimmune pancreatitis across 4 studies. DISCUSSION There is an increased risk of PDAC in patients with CP, and incidence rates increase with CP disease duration. Our results indicate that PDAC surveillance may be considered in individuals with long-standing CP.

Abstract
BACKGROUND The dose-response association between alcohol consumption and the subsequent pancreatic cancer risk by individuals' glycaemic status is unclear. RESEARCH DESIGN AND METHOD This large-scale nationwide cohort study included 9,514,171 adults without cancer who underwent health examinations under the Korean National Health Insurance Service in 2009 and were followed-up until December 2017 for pancreatic cancer development. Multivariable Cox proportional hazards regression analysis was performed. RESULTS During a median follow-up period of 7.3 years, 12,818 patients were newly-diagnosed with pancreatic cancer. Among individuals with normoglycemia, a J-shaped association was observed between the frequency of alcohol consumption (1-2 and ≥5 days/week: hazards ratio [HR]; 95% CI, 0.91; 0.85-0.97 and 1.13; 1.002-1.27, respectively) and pancreatic cancer risk, after adjusting for potential confounders. However, in patients with impaired fasting glucose (IFG), pancreatic cancer risk increased with increased frequency and average daily amount of alcohol consumption (all P for trend <0.01). IFG combined with heavy alcohol consumption (30 g/day) was associated with 38% increased pancreatic cancer risk (HR, 1.38; 95% CI, 1.23-1.54). Diabetes was associated with an increased pancreatic cancer risk regardless of alcohol consumption and 70% increased risk even in non-drinkers (HR, 1.70; 95% CI, 1.61-1.80). CONCLUSIONS The J-shaped dose-response association between alcohol consumption and pancreatic cancer risk was observed only in individuals with normoglycemia, not in patients with IFG and diabetes. Complete alcohol abstinence may help reduce pancreatic cancer risk in patients with IFG and diabetes.

Abstract
TH2 cells and innate lymphoid cells 2 (ILC2) can stimulate tumor growth by secreting pro-tumorigenic cytokines such as interleukin-4 (IL-4), IL-5, and IL-13. However, the mechanisms by which type 2 immune cells traffic to the tumor microenvironment are unknown. Here, we show that oncogenic KrasG12D increases IL-33 expression in pancreatic ductal adenocarcinoma (PDAC) cells, which recruits and activates TH2 and ILC2 cells. Correspondingly, cancer-cell-specific deletion of IL-33 reduces TH2 and ILC2 recruitment and promotes tumor regression. Unexpectedly, IL-33 secretion is dependent on the intratumoral fungal mycobiome. Genetic deletion of IL-33 or anti-fungal treatment decreases TH2 and ILC2 infiltration and increases survival. Consistently, high IL-33 expression is observed in approximately 20% of human PDAC, and expression is mainly restricted to cancer cells. These data expand our knowledge of the mechanisms driving PDAC tumor progression and identify therapeutically targetable pathways involving intratumoral mycobiome-driven secretion of IL-33.

Abstract
OBJECTIVES The Enriching New-onset Diabetes for Pancreatic Cancer (END-PAC) model identified patients at high-risk for pancreatic ductal adenocarcinoma (PDAC) more than 6 months before diagnosis. The current study aimed to validate the END-PAC model using a large, state-mandated health care provider database. METHODS A retrospective cohort study of patients older than 50 years that had a diagnosis of new-onset diabetes (NOD) between 2006 and 2015. A risk score was assigned according to the END-PAC model. Patients who developed PDAC over the 3-year period after NOD diagnosis were identified using the Israeli National Cancer Registry. RESULTS Twenty-three percent (1245/5408) of NOD patients were classified as high-risk, of them 32 (2.6%) developed PDAC. Median follow-up time from NOD detection to PDAC diagnosis was 609 days (interquartile range, 367-997). The hazard ratio for PDAC diagnosis among individuals at the high-risk group compared with the low-risk group was 5.70 (95% confidence interval, 2.93-11.06). Using the high-risk group as the screening threshold, the sensitivity, specificity, positive predictive value and negative predictive value of the model were 54.2%, 76.98%, 2.57%, and 99.4%, respectively. Area under the curve of the model was 0.69. CONCLUSIONS Our findings support the robustness, generalizability and clinical applicability of the END-PAC model.

Abstract
BACKGROUND Circular RNAs (circRNAs) play important roles in many biological processes. However, the detailed mechanism underlying the critical roles of circRNAs in cancer remains largely unexplored. We aim to explore the molecular mechanisms of circRTN4 with critical roles in pancreatic ductal adenocarcinoma (PDAC). METHODS CircRTN4 expression level was examined in PDAC primary tumors. The oncogenic roles of circRTN4 in PDAC tumor growth and metastasis were studied in mouse tumor models. Bioinformatics analysis, luciferase assay and miRNA pulldown assay were performed to study the novel circRTN4-miRNA-lncRNA pathway. To identify circRTN4-interacting proteins, we performed circRNA-pulldown and mass spectrometry in PDAC cells. Protein stability assay and 3-Dimensional structure modeling were performed to reveal the role of circRTN4 in stabilizing RAB11FIP1. RESULTS CircRTN4 was significantly upregulated in primary tumors from PDAC patients. In vitro and in vivo functional studies revealed that circRTN4 promoted PDAC tumor growth and liver metastasis. Mechanistically, circRTN4 interacted with tumor suppressor miR-497-5p in PDAC cells. CircRTN4 knockdown upregulated miR-497-5p to inhibit the oncogenic lncRNA HOTTIP expression. Furthermore, we identified critical circRTN4-intercting proteins by circRNA-pulldown in PDAC cells. CircRTN4 interacted with important epithelial-mesenchymal transition (EMT)- driver RAB11FIP1 to block its ubiquitination site. We found that circRTN4 knockdown promoted the degradation of RAB11FIP1 by increasing its ubiquitination. Also, circRTN4 knockdown inhibited the expression of RAB11FIP1-regulating EMT-markers Slug, Snai1, Twist, Zeb1 and N-cadherin in PDAC. CONCLUSION The upregulated circRTN4 promotes tumor growth and liver metastasis in PDAC through the novel circRTN4-miR-497-5p-HOTTIP pathway. Also, circRTN4 stabilizes RAB11FIP1 to contribute EMT.

Abstract
AIM Pancreatic cancer is the 11th most common cancer in the world. The importance of early diagnosis and treatment for curative treatment is very high. Many studies have shown a relationship between diabetes mellitus (DM), smoking, genetic factors, obesity, nutritional habits and sedentary life and pancreatic ductal adenocarcinoma (PDAC). In this study, we aimed to investigate the relationship between DM onset age and PDAC. MATERIALS AND METHODS 158 patients with PDAC and DM were compared with 244 patients with DM in the control group. We retrospectively analyzed PDAC risk factors with a focus on DM onset age. RESULTS It was calculated that the risk of PDAC increased 8.5 times in patients diagnosed with DM after 60 years of age compared to those diagnosed with DM before 60 years of age (HR = 8.54, 95% CI 5.66-12.90, p<0.0001). The interval between the diagnosis of DM and the diagnosis of PDAC peaked at 32 months (95% CI 27.90-35.56). When the age of DM onset was evaluated, it was observed that peaks were around 50 years in the group without PDAC and 60 years in the group with PDAC. CONCLUSION In patients with DM onset after the age of 60, we recommend keeping in mind the increased risk of PDAC and evaluating these patients for PDAC, even if they are asymptomatic.

Abstract
INTRODUCTION Pancreatic cancer (PC) is a malignant tumor with significantly increased incidence and poor prognosis. Its extremely poor prognosis is generally attributed to its early invasion and metastasis as well as the presence of chemotherapy resistance, which may be related to the potential role of cancer stem cells (CSCs). Doublecortin-like kinase 1 (Dclk1) has been recognized to be a marker of CSCs in PC, showing intimate association with its occurrence, metastasis, and poor prognosis. AREAS COVERED A review serves to provide a comprehensive overview of Dclk1 in the pathogenesis, diagnosis, prognosis, and treatment in PC. EXPERT OPINION Searching for potential key biomarkers for PC has been an urgent issue to be addressed. The expression of Dclk1 is increasing in PC, and its effect is linked to the mutant Kras, supporting that it may be a potential new target. Therefore, it highlights Dclk1 as a candidate biomarker and therapeutic target in future clinical application.

Abstract
Aquaporins are water channel proteins facilitating passive transport of water across cellular membranes. Aquaporins are over- or ectopically expressed in a multitude of cancers, including pancreatic ductal adenocarcinoma, which is a highly aggressive cancer with low survival rate. Evidence suggests that aquaporins can affect multiple cellular processes involved in cancer development and progression including epithelial-mesenchymal transition, cellular migration, cell proliferation, invasion, and cellular adhesions. In pancreatic ductal adenocarcinoma, aquaporin-1, aquaporin-3, and aquaporin-5 are overexpressed and have been associated with metastatic processes and poor survival. Thus, aquaporin expression has been suggested as diagnostic markers and therapeutic targets in pancreatic ductal adenocarcinoma.

Abstract
OBJECTIVE The meta-analysis was conducted to test the link between pancreatic cancer (PC) risk and dietary inflammatory index (DII®) score. DESIGN Systematic review and meta-analysis. SETTING We searched PubMed, Embase, Web of Science and the Cochrane Library up to 22 November 2020 to identify the relevant studies. Studies that reported the risk estimates and the corresponding 95 % CI for the DII category and PC risk were included. The effect sizes were pooled using the random-effects model. Dose-response analysis was conducted where possible. PARTICIPANTS Two prospective cohort studies of 634 705 participants (3152 incident cases), and four case-control studies of 2737 cases and 4861 controls. RESULTS Overall, the pooled risk ratio (RR) indicated that individuals in the highest category compared with the lowest category had an increased PC risk (RR = 1·45; 95 % CI 1·11, 1·90; P = 0·006). Meanwhile, significant heterogeneity was also revealed. The dose-response meta-analysis indicated that a 1-unit increase in the DII score was associated with the PC risk (RR = 1·08; 95 % CI 1·002, 1·166; P = 0·045; I2 = 94·1 %, P < 0·001). Nonlinear result showed an increased risk of moving from fewer to more inflammatory borders with increasing DII score (Pnonlinearity = 0·003; I2 = 76·5 %, P < 0·001). Subgroup analyses found that significant positive association between PC risk and DII score appeared to be in case-control studies (RR = 1·70; 95 % CI 1·16, 2·50; P = 0·007) and studies with ≤ 31 DII components (RR = 1·76; 95 % CI 1·14, 2·72; P = 0·011). CONCLUSION These findings suggested dietary habits with high inflammatory features (high DII score) might increase PC risk.

Abstract
Experimental studies suggest that abnormal levels of Ca, Mg and phosphorus are implicated in pancreatic carcinogenesis. We investigated the associations between intakes of these minerals and the risk of pancreatic cancer in a case-control study conducted in 1994-1998. Cases of pancreatic cancer (n 150) were recruited from all hospitals in the metropolitan area of the Twin Cities and Mayo Clinic, Minnesota. Controls (n 459) were randomly selected from the general population and frequency matched to cases by age, sex and race. All dietary variables were adjusted for energy intake using the residual method prior to data analysis. Logistic regression was performed to evaluate the associations between intake of three nutrients examined and the risk of pancreatic cancer. Total intake of Ca (936 v. 1026 mg/d) and dietary intake of Mg (315 v. 331 mg/d) and phosphorus (1350 v. 1402 mg/d) were significantly lower in cases than in controls. After adjustment for confounders, there were not significant associations of total and dietary intakes of Ca, Mg and phosphorus with the risk of pancreatic cancer. In addition, no significant interactions exist between intakes of these minerals and total fat on pancreatic cancer risk. In conclusion, the present study does not suggest that intakes of Ca, Mg and phosphorus were significantly associated with the risk of pancreatic cancer.
