This study aimed to assess the feasibility of establishing PDOs from resected specimens in periampullary tumors.Methods: Patients undergoing surgery for suspected periampullary cancer were included. PDO protocol amendments were tested, with organoid take rate as outcome measure. Samples from resected specimens were processed and expanded per protocol. Pooled estimate of take rates of PDOs in PDAC was derived from literature search.Results: 23 specimens were available for PDO, of which 10 were PDAC. In 15 patients other histopathology was found: neuroendocrine tumors (NET; n = 2), neuroendocrine carcinoma (NEC; n = 1), intraductal papillary mucinous neoplasm (IPMN; n = 4), distal cholangiocarcinoma (dCCA; n = 1), ampullary carcinoma (n = 1), duodenal carcinoma (n = 1), intra-ampullary papillary tubular neoplasm (IAPN; n = 1), indeterminate PDAC/ampullary carcinoma(n = 1), and one patient with chronic inflammation/fibrosis. Organoid cultures were grown from 7 of 10 (70 %) PDAC, 1 dCCA, 1 NEC, 1 duodenal carcinoma, 1 indeterminate tumor type and 1 ampullary carcinoma (i.e. 12/18; 66.7 % across periampullary cancers). Overall take rate of PDOs was 12 of 23 (52.2 %) for all tumors. A pooled mean estimate PDO take rate of 62.3 % (95 % CI:54.8-69.3 %) was reported across available studies in the literature.Conclusion: In the current study, we found that PDOs could be established from resected pancreatic tumors in over half of resected periampullary tumors, and highest in PDACs. As such, generating a pancreatic cancer PDO biobank for translational research was feasible after cryopreservation.","PeriodicalId":19976,"journal":{"name":"Pancreatology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142903410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main inclusion criterion was the final diagnosis of a mucinous PCL. The results from EUS-FNA were analyzed in the context of outcome gathered from medical records of follow-up until February 2021.Results: Of 334 patients undergoing EUS-FNA, 171 (51 %) had a final diagnosis of a mucinous PCL. 29/171 (17 %) patients were diagnosed with HGD or adenocarcinoma <6 months after EUS-FNA, with 28/29 (97 %) patients having at least one worrisome feature on EUS-FNA. A solid component in mucinous PCLs on EUS was independently associated with the presence of HGD or adenocarcinoma (OR 23.6, 95 % CI 6.1-91.6, p < .001). A total of 4/142 (3 %) patients developed adenocarcinoma during the follow-up period (median = 61.4 months). Overall, in 80/82 (98 %) of the patients without worrisome features on EUS-FNA, HGD or adenocarcinoma was not detected. Six of the 21 (29 %) patients with HGD or adenocarcinoma who underwent surgery as initial management died from pancreatic cancer during follow-up.Conclusions: EUS-FNA is useful for the risk stratification of mucinous PCLs. The low incidence of adenocarcinoma over time after a negative EUS-FNA may allow for a less resource intensive surveillance strategy.","PeriodicalId":19976,"journal":{"name":"Pancreatology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142910064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to evaluate trends in endoscopic ultrasound (EUS) use and agreement between cross-sectional imaging and EUS for specific pancreas cystic lesion (PCL) features.Methods: This retrospective cohort study included consecutive adults undergoing EUS for suspected IPMN detected with cross-sectional imaging (CT/MRCP) between 2013 and 2015 (Cohort 1) and 2018-2020 (Cohort 2). Clinical, radiographic, EUS, cytologic, and outcomes data were collected. IPMN were defined as high-risk/worrisome (having any Fukuoka high risk (HR) or worrisome feature (WF)), low risk (cyst size 10-29.9 mm, without Fukuoka HR or WF), or very low risk (cyst size <10 mm, without Fukuoka HR or WF). Chi-square, Fisher's exact test, Wilcoxon rank-sum test and Kappa statistics were used. Impact of the COVID-19 pandemic was assessed via post-hoc sensitivity analysis.Results: Of 711 patients, 292 (41.1 %) were in Cohort 1. More patients in Cohort 1 underwent EUS for non-high risk/non-worrisome PCL on pre-EUS imaging (65.8 % vs. 54.9 %, P < 0.01). Good agreement between pre-EUS imaging and EUS for WF (84.1 %) and HR (96.6 %) was seen. EUS-FNA impacted surveillance and surgical referral in 29.5 % (P = 0.51). Median surveillance duration was 917 days (IQR 367, 1439 days), during which pancreatic ductal adenocarcinoma (PDAC) was diagnosed in 7.5 % (P = 0.11).Conclusions: In this series EUS over-utilization for low risk IPMN improved over time reflecting more conservative guidelines, without changing PDAC diagnosis rates. There was good agreement between cross-sectional imaging and EUS for specific PCL features.","PeriodicalId":19976,"journal":{"name":"Pancreatology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142872784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
