Italian registry of families at risk of pancreatic cancer: AISP Familial Pancreatic Cancer Study Group
No full textPancreatic cancer is one of the main causes of cancer-related death worldwide, with a survival rate around 9%. In Italy 13,500 new cases of pancreatic cancer occurred in 2019. It is estimated that at least 5% have a hereditary background. Surveillance is advisable for healthy individuals with specific genetic syndromes with or without family history of pancreatic cancer or members of families with multiple cases of pancreatic cancer, irrespective of genetic syndromes. In 2010 the Italian Association for the Study of the Pancreas (AISP) defined criteria to include individuals in such surveillance programs with the first-round results published in 2019. In order to include other categories at high-risk and increase the diagnostic yield of surveillance, these criteria have recently been modified. The present position paper presents the updated criteria of the Italian Registry of Families at Risk of Pancreatic Cancer (IRFARPC) with their diagnostic yield calculation. Also, AISP priority projects concerning: (a) increasing awareness of citizens and primary care physicians through a dedicated App; (b) increasing access to germline testing to personalize surveillance; (c) measuring psychological impact of surveillance; (d) investigating the role of risk-modifiers and (e) evaluating the cost-effectiveness and ability to save lives of the program are briefly presented

The Italian registry of families at risk for pancreatic cancer (IRFARPC): implementation and evolution of a national program for pancreatic cancer surveillance in high-risk individuals
No full text: Screening programs for early detection and treatment of pancreatic cancer (PC) and its precursor lesions are increasingly implemented worldwide to reduce disease-specific lethality. Given the relatively low prevalence of the disease, the ideal target of such approaches is an enriched cohort of individuals harboring a lifetime risk of developing PC significantly higher compared to the general population, given either a substantial aggregation of PC cases in their family (i.e. familial pancreatic cancer) or a genomic landscape enriched with pathogenic variants associated with pancreatic carcinogenesis (i.e. mutation carriers). In Italy, a national registry for the census and surveillance of high-risk individuals for PC was launched in 2015, enrolling some 1200 subjects as of today. In this perspective, the scientific background, multi-level structure, and evolution of IRFARPC are outlined, as well as its long-term results, future developments, and areas for improvement
The Actual Prevalence of Symptoms in Pancreatic Cystic Neoplasms: A Prospective Propensity Matched Cohort Analysis
No full textBackground: The prevalence of symptoms in pancreatic cystic neoplasms (PCNs) is mainly based on retrospective surgical series. The aim of this study is to describe the actual prevalence of symptoms in PCNs under surveillance. Methods: Patients with PCNs under surveillance observed from 2015 to 2017 were submitted to magnetic resonance imaging (MRI) and a specific interview. An identical survey was carried out on a control population matched for age, sex, and comorbidities in which any pancreatic disease was excluded by MRI. Results: Two groups of 184 individuals were compared. Patients with PCNs have a similar prevalence of abdominal pain when compared to controls (35.2 vs. 28.8, p = 0.2). PCNs in the distal pancreas experienced a significantly increased prevalence of abdominal pain (42.3 vs. 28.8%, p = 0.04), whereas size and presumed connection with the ductal system did not affect the prevalence of abdominal pain. PCNs associated with abdominal pain did not differ in terms of clinical and radiological features from asymptomatic ones. Conclusion: Patients with PCNs under surveillance have a similar prevalence of abdominal pain when compared to a matched population of controls. Abdominal pain might not correlate with radiological signs of malignancy
Editorial: Machine learning approaches for monitoring mental health and substance abuse using social media data
No full textThe rapid growth of social media platforms has changed how individuals express
and share personal habits and experiences, including those related to mental health and
substance use (1). In parallel, advances in machine learning (ML) have provided powerful
tools for analyzing this rich and abundant data source, creating new possibilities for public
health research (2).
This Research Topic brings together several studies that explore the intersection of
these two domains, employing ML techniques to monitor, analyze, and predict mental
health conditions and substance abuse patterns using social media data, illustrating how
innovative approaches could impact public health monitoring through the lens of social
media data
Expert Judgment Supporting a Bayesian Network to Model the Survival of Pancreatic Cancer Patients
Full text linkPurpose: Pancreatic cancer is known for its poor prognosis. The most effective treatment combines surgery with peri-operative chemotherapy. Current prognostic tools are designed to predict patient outcomes and inform treatment decisions based on collected data. Bayesian networks (BNs) can integrate objective data with subjective clinical insights, such as expert opinions, or they can be independently based on either element. This pilot study is one of the first efforts to incorporate expert opinions into a prognostic model using a Bayesian framework. Methods: A clinical hybrid BN was selected to model the long-term overall survival of pancreatic cancer patients. The SHELF expert judgment method was employed to enhance the BN’s effectiveness. This approach involved a two-phase protocol: an initial single-center pilot phase followed by a definitive international phase. Results: Experts generally agreed on the distribution shape among the 12 clinically relevant predictive variables identified for the BN. However, discrepancies were noted in the tumor size, age, and ASA score nodes. With regard to expert concordance for each node, tumor size, and ASA score exhibited absolute concordance, indicating a strong consensus among experts. Ca19.9 values and resectability status showed high concordance, reflecting a solid agreement among the experts. The remaining nodes showed acceptable concordance. Conclusions: This project introduces a novel clinical hybrid Bayesian network (BN) that incorporates expert elicitation and clinical variables present at diagnosis to model the survival of pancreatic cancer patients. This model aims to provide research-based evidence for more reliable prognosis predictions and improved decision-making, addressing the limitations of existing survival prediction models. A validation process will be essential to evaluate the model’s performance and clinical applicabilit
Adjuvant chemotherapy is associated with improved postoperative survival in specific subtypes of invasive intraductal papillary mucinous neoplasms (IPMN) of the pancreas: it is time for randomized controlled data
No full textBackground: Very little is known about adjuvant chemotherapy for invasive Intraductal Papillary Mucinous Neoplasms (IPMNs) of the pancreas. The aim was to assess whether adjuvant chemotherapy affects survival.Methods: Retrospective evaluation of invasive IPMNs. Patients treated with surgery alone or followed by adjuvant chemotherapy were compared in terms of survival.Results: A total of 102 invasive IPMNs were analyzed. Median follow-up was 72 (5-318) months and 18.6% received adjuvant chemotherapy. Overall, recurrence rate was 40.2%, while 5-year overall survival and disease specific survival (DSS) were 65.3% and 69.4%, respectively. N1 disease (HR5.58, CI95% 2.49-12.51, p < 0.01), tubular type (HR2.35, CI95% 1.71-4.82, p = 0.05) and G3 tumors (HR4.54, CI95% 2.12-15.49, < 0.01) were predictors of reduced DSS. Overall, there was no difference in the 5-year DSS comparing patients treated with adjuvant chemotherapy to surgery alone (61.8 vs. 69.4%, p = 0.8). Adjuvant chemotherapy significantly improved DSS only in N1 (5-years-DSS 76 vs. 35.8%, p = 0.01) and tubular carcinomas (5-years-DSS 88.9 vs. 53%, p = 0.03).Conclusions: Adjuvant therapy improves survival only in invasive IPMNs with nodal disease or tubular differentiation. Future trials are needed to improve the level of evidence about adjuvant chemotherapy
Adjuvant Therapy After Upfront Resection of Resectable Pancreatic Cancer: Patterns of Omission and Use-A Prospective Real-Life Study
Full text linkBackground: Little is known about adjuvant therapy (AT) omission and use outside of randomized trials. We aimed to assess the patterns of AT omission and use in a cohort of upfront resected pancreatic cancer patients in a real-life scenario. Methods: From January 2019 to July 2022, 317 patients with resected pancreatic cancer and operated upfront were prospectively enrolled in this prospective observational trial according to the previously calculated sample size. The association between perioperative variables and the risk of AT omission and AT delay was analyzed using multivariable logistic regression. Results: Eighty patients (25.2%) did not receive AT. The main reasons for AT omission were postoperative complications (38.8%), oncologist's choice (21.2%), baseline comorbidities (20%), patient's choice (10%), and early recurrence (10%). At the multivariable analysis, the odds of not receiving AT increased significantly for older patients (odds ratio [OR] 1.1, p < 0.001), those having an American Society of Anesthesiologists score ≥II (OR 2.03, p = 0.015), or developing postoperative pancreatic fistula (OR 2.5, p = 0.019). The likelihood of not receiving FOLFIRINOX as AT increased for older patients (OR 1.1, p < 0.001), in the presence of early-stage disease (stage I-IIa vs. IIb-III, OR 2.82, p =0.031; N0 vs. N+, OR 3, p = 0.03), and for patients who experienced postoperative major complications (OR 4.7, p = 0.009). A twofold increased likelihood of delay in AT was found in patients experiencing postoperative complications (OR 3.86, p = 0.011). Conclusions: AT is not delivered in about one-quarter of upfront resected pancreatic cancer patients. Age, comorbidities, and postoperative complications are the main drivers of AT omission and mFOLFIRINOX non-use. Clinicaltrials registration: NCT03788382
Psychological distress in patients under surveillance for intraductal papillary mucinous neoplasms of the pancreas: The "Sword of Damocles" effect calls for an integrated medical and psychological approach a prospective analysis
No full textIntroduction: Most intraductal papillary mucinous neoplasms (IPMNs) of the pancreas can be safely surveilled. Their psychological impact is not known. The aim of this study is to obtain a psychological profile of patients under surveillance and compare the results to patients undergoing surgery.Methods: Patients under surveillance for IPMNs evaluated between 2017 and 2019 at the pancreatic cysts clinic of The Pancreas Institute of Verona were compared to patients undergoing surgery for the same disease. Patients with high-risk stigmata were excluded in both groups. Patients were profiled with the Barratt Simplified Measure of Socio-Economic Status (BSMSS), the Brief Coping Orientation to Problems Experienced (Brief-COPE), the Perceived Stress Scale (PSS), the Symptom Checklist-90 and the Short Form Health Survey (SF-36). Age, sex, BSMSS and Brief-COPE were used to match patients with the propensity score as potential sources of bias.Results: Two hundred patients were profiled. After the matching, 74 patients under surveillance were compared to 74 patients who underwent surgery. Patients under surveillance reported significantly increased scores for symptoms such as somatization (0.71 vs. 0.54, p = 0.032), depression (0.45 vs 0.31, p = 0.047) and anxiety (0.45 vs. 0.27, p = 0.002). They also reported a reduced health perception in the domain of physical role functioning (54 vs. 68, p = 0.046).Conclusion: Patients under surveillance for a presumed IPMN experience anxiety and stress and feel less healthy than do patients undergoing surgery. This reduction in quality of life should always be taken into account and warrants an integrated medical-psychological approach in selected cases. (C) 2020 IAP and EPC. Published by Elsevier B.V.

Does the surgical waiting list affect pathological and survival outcome in resectable pancreatic ductal adenocarcinoma?
No full textBackground: High-volume centers have to deal with long surgical waiting-lists leading to a potential delay in treatment. This study assessed whether a longer time from diagnosis to surgery worsened pathological and survival outcomes in resectable pancreatic ductal adenocarcinoma (PDAC). Methods: A retrospective analysis of patients treated for resectable PDAC. Difference in size between preoperative CT-scan and specimen, pathological features, the rate of vascular and R1 resections as well as recurrence and survival were analyzed depending on the waiting time using a 30-day cut-off. Results: Waiting more than 30 days for surgery was associated with an increase in tumor size on specimen when compared with CT-scan (+3 vs. +1 mm, p = 0.04). T and N status, rate of vascular resection, grading, perineural and lymphovascular infiltration, and R1 rates did not differ between groups, as well as tumor recurrence (48.8% vs. 48.9%, p = 0.5) and survival (31 vs. 29 months, p = 0.7). For PDAC < 20 mm, waiting less than 30 days improved overall survival (p = 0.02). Conclusion: The duration of the surgical waiting-list did not affect pathological features and survival. Delayed surgery was associated with increased cancer size on the specimen. However, surgery should not be delayed for PDACs < 20 mm as this may negatively affect the prognosis
