Background: The role and eligibility population of conversion surgery for mPDAC remains controversial in the era of NAT. Methods: A consecutive cohort of patients diagnosed with mPDAC and treated with NAT followed by conversion surgery between 2019 and 2021 were confirmed from a prospective database maintained by the Department of Pancreatic Hepatobiliary Surgery of Changhai Hospital. In accordance with residual metastases and technical resectability after NAT, patients were classified as the complete pathological response of metastases (ypM0) resection group, residual metastases (ypM1) resection group, and exploration group. Median overall survival (mOS) was calculated using the Kaplan-Meier method, uni- and multivariable cox regression was performed to identify clinicopathological predictors of OS. Results: A total of 244 patients with mPDAC were identified from the prospective database, with 19 (7.8%) patients who underwent ypM0 resection, 22 (9.0%) underwent ypM1 resection, and 23 (9.4%) underwent explorative laparotomy. The mOS was 32.6 months for ypM0 resected patients, 15.1 months for ypM1 resected patients, and 13.4 months for those who underwent explorative laparotomy (P < .001). Univariable and multivariable Cox regression analyses confirmed that ypM0 resection, normalization of preoperative CA19-9 levels, and continued adjuvant therapy were independent prognostic factors of conversion surgery for mPDAC after NAT. Subgroup analyses revealed that oligometastases and continued adjuvant therapy were associated with improved prognosis in the ypM1 resection group. Conclusion: In patients with mPDAC who underwent NAT followed by conversion surgery, the complete pathological response of metastases, normalization of preoperative CA19-9 levels, and continued adjuvant therapy were independent risk factors for prognosis. Patients with residual oligometastases after treatment were expected to prolong survival through resection. These patients may benefit from conversion surgery and should be potential candidates for this treatment strategy.","PeriodicalId":92925,"journal":{"name":"Journal of pancreatology","volume":"6 1","pages":"110 - 118"},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45798999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its expression pattern in pancreatic ductal adenocarcinoma (PDAC) remains contradictory. In addition, its clinicopathologic and prognostic significance in this malignancy has not been elucidated. Methods: Expression of MMP15 was immunohistochemically detected in a tissue microarray of formalin-fixed paraffin-embedded samples from 95 patients of PDAC after surgery. Its expression pattern and relations with clinicopathologic factors and disease-specific survival (DSS) were then evaluated. Finally, its expression and prognostic value were measured in the on-line publically available database, GEPIA, using TCGA data. Results: In comparison of all samples and 75 paired ones, MMP15 expression in tumor tissues was all significantly higher than that in para-tumor ones (P = .037 and .016). Furthermore, tumoral MMP15 expression was associated with peri-neural invasion. Survival analysis showed that patients with high tumoral MMP15 expression had significantly poorer DSS than those with low MMP15 expression (P = .0059). In univariate and multivariate Cox regression tests, tumoral MMP15 expression was all significantly predictive for DSS. In the on-line publically available GEPIA database, MMP15 was also overexpressed in PDAC, but was not found to be prognostic. Conclusion: Our results indicated that MMP15 expression was elevated in operable PDAC and might have a prognostic impact.","PeriodicalId":92925,"journal":{"name":"Journal of pancreatology","volume":"6 1","pages":"96 - 100"},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45630344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we review the recent progress in the field of molecular genetics and therapeutic targets of PanNETs. The key genomic alterations, including MEN1, ATRX/DAXX, mammalian target of rapamycin (mTOR), DNA damage and repair associated genes, vascular endothelial growth factor receptor (VEGFR) and SSTRs, and epigenetic aberrations in PanNETs are discussed.

Therefore, this study aims to explore the expression of potassium voltage-gated channel subfamily H member 2 (KCNH2) in PC and its relationship with clinicopathological parameters and the related mechanisms. Methods: GEPIA database and immunohistochemical staining were used to analyze the difference in KCNH2 expression between PC and adjacent tissue in RNA and protein levels. Chi-squared test was used to evaluate the relationship between KCNH2 expression and clinicopathological features. The Cox regression model was used for multivariate analysis and univariate analysis. Histological diagnosis was performed according to World Health Organization (WHO) criteria to evaluate the relationship between KCNH2 expression and clinicopathological features. Results: KCNH2 expression was upregulated in PC compared with normal pancreatic tissue. In addition, the knockdown of KCNH2 inhibits PC cell proliferation, migration, invasion, and epithelial-mesenchymal transformation and promotes their apoptosis. In addition, clinical data showed that the abnormal expression of KCNH2 in PC was related to the tumor stage. Patients with high expression of KCNH2 had a poor prognosis. Conclusions: KCNH2 is expected to be a novel targeted molecule in treating PC.","PeriodicalId":92925,"journal":{"name":"Journal of pancreatology","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135904906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
