Based on the Grading of Recommendations Assessment, Development, and Evaluation system, the guidelines have conducted a discussion on the indication, regimen selection, therapeutic effect evaluation, pathological diagnosis, surgery strategy, etc. The guidelines have quantified the evidence level of the current clinical researches and provided recommendations for the clinical practice in neoadjuvant therapy of pancreatic cancer. The guidelines have highlighted the role of multiple disciplinary team and represented the conversion of treatment concepts in pancreatic cancer. Neoadjuvant therapy has prolonged the survival of part of pancreatic cancer patients. However, more high-quality clinical researches are in urgent need to improve the level of evidence, optimize the clinical practice, and improve the survival of patients.","PeriodicalId":92925,"journal":{"name":"Journal of pancreatology","volume":"4 1","pages":"135 - 145"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47057749","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}

Since the early 1990s, laparoscopic techniques have been applied to a growing number of pancreas surgeries, and great progress has been achieved in laparoscopic pancreaticoduodenectomy. As surgeons become proficient in laparoscopic pancreaticoduodenectomy techniques, laparoscopic techniques are gradually used in other pancreatic surgeries, such as laparoscopic distal pancreatectomies and laparoscopic duodenum-preserving pancreatic head resection (LDPPHR), which may benefit patients by reducing postoperative pain and hospital stays and providing a quick recovery to normal activity. Recently, a great number of literature have introduced LDPPHR. It is a good surgical method for benign and low-grade malignant tumors of the pancreatic head. Although LDPPHR is technically feasible, it is not yet generally practicable and limited to highly skilled endoscopic surgeons, and the long-term results after LDPPHR are still not well defined. This article aims to provide a literature review of LDPPHR to assess its feasibility, safety, postoperative recovery, and future outlook according to early experiences of this technique.","PeriodicalId":92925,"journal":{"name":"Journal of pancreatology","volume":"4 1","pages":"146 - 152"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42289442","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}

Inhibition of stearoyl-CoA desaturase 1 (SCD1) suppresses cancer proliferation and might act as a novel chemotherapy supplement, but this has not been investigated in PC. Here, the effects of SCD1 inhibitor CAY10566 supplemented with gemcitabine treatment (gemcitabine+CAY10566) on PC cell viability, apoptosis, phenotype, fatty acid content, platelet-derived growth factor release, and cell size were investigated. Methods: Human PC cell line (PANC-1) was treated with SCD1 inhibitor CAY10566 with or without gemcitabine. Cell viability was assayed using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide and apoptosis and phenotype were determined using flow cytometry. Fatty acid content and platelet-derived growth factor release were measured by enzyme-linked immunosorbent assay. Cell size was determined using scanning electron microscopy. Results: Half-maximal inhibitory concentration of gemcitabine or CAY10566 significantly reduced PANC-1 viability compared to gemcitabine alone (P < .0001). No significant differences in the phenotype of phosphatidylserine, tissue factor or basigin expression were detected at therapeutic doses (P > .05). Apoptosis was significantly increased following incubation with CAY10566 (P < .05). Fatty acid content of cells was significantly higher following gemcitabine treatment compared to CAY10566 alone or gemcitabine+CAY10566 (P < .05). Platelet-derived growth factor released by gemcitabine-treated cells was significantly increased compared to 142 nM CAY10566 alone or gemcitabine+CAY10566 (P < .01). CAY10566 did not affect the size of isolated tumor cells but gemcitabine+CAY10566 significantly increased the size compared to the control (P < .05). Cell viability decreased significantly after the treatment with gemcitabine+CAY10566 compared with CAY10566 alone (P < .05) and gemcitabine alone (P < .01). However, when cycles of chemotherapy were mimicked and treatment was removed, the number of cell viability was significantly reduced (P < .05).

Progressive EPN leading to necrotizing fasciitis of the retroperitoneum and abdominal wall has been reported. However, extension of retroperitoneal necrosis to the scrotum causing Fournier's gangrene is uncommon. We present a case of 39-year-old male admitted with severe acute pancreatitis requiring prolonged mechanical ventilation. He was managed with percutaneous drainage and culture specific antibiotics during the 1st month of hospital stay. During the 3rd month of hospital stay, the patient started developing pain and ulceration over the scrotum. He was diagnosed with Fournier's gangrene based on clinical examination and was planned for debridement. During surgery, the track extending up to the deep inguinal ring was widened and drain was placed into the right lateral pelvic wall through the deep ring via a separate stab incision to reduce further scrotal wound contamination. The case highlights a rare but potentially fatal complication of Fournier's gangrene following severe acute necrotizing pancreatitis and the importance of measures to prevent further contamination of scrotum after surgical debridement. Concomitant management of two potentially fatal conditions poses numerous challenges.","PeriodicalId":92925,"journal":{"name":"Journal of pancreatology","volume":"4 1","pages":"130 - 133"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46358792","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}

We aimed to conduct survival and safety analyses in LAPC patients after treatment with IRE combined with chemotherapy. Methods: A total of 64 patients with LAPC who had received IRE and chemotherapy were retrospectively collected from August 2015 to March 2019 at Sun Yat-sen University Cancer Center. Overall survival (OS) and progression-free survival (PFS) were evaluated using Kaplan-Meier method and compared by the log-rank test. A multivariate Cox regression model was used to determine the prognostic factors of survival. The perioperative complications of IRE were also evaluated. The study was approved by the Institutional Review Board of Sun Yat-sen University Cancer Center (approval No. C2021-003). Results: The median survival of all included patients were 24.63 (95% confidence interval: 21.78–27.49) for overall survival and 13.00 (95% confidence interval: 8.81–17.19) months for progression-free survival, with 96.8%, 51.9%, 18.3%; and 52.3%, 21.5%, 7.9% as the 1-, 2- and 3-year OS and PFS rates, respectively. Tumor size [OS, hazard ratio (HR)=1.768, P = 0.048; PFS, HR = 0.304, P = 0.010], neoadjuvant chemotherapy (OS, HR = 0.338, P = 0.030; PFS, HR = 0.358, P = 0.034), carbohydrate antigen 19-9 variation after IRE (OS, HR = 19.320, P = 0.003; PFS, HR = 14.591, P = 0.021) and tumor response after neoadjuvant chemotherapy (OS, HR = 8.779, P = 0.033; PFS, HR = 5.562, P = 0.008) were predictive factors of survival in patients with LAPC after IRE. Complications were observed in 20.3% of patients. Grade B pancreatic fistula was the most common complication. The complication rates of the late treatment group (6.1%) were significantly lower than those of the first 15 patients after IRE treatment (66.7%). The median length of hospital stay of late treatment group was 8.6 days, which was also shorter than that of the early treatment group (10.0 days). Conclusions: IRE combined with chemotherapy could improve survival of LAPC patients with acceptable complication rates. Therefore, it may be a suitable method for LAPC but should be validated in prospective randomized trials.","PeriodicalId":92925,"journal":{"name":"Journal of pancreatology","volume":"5 1","pages":"27 - 35"},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43072682","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}

Mechanisms (a) and (b) result in metastatic lesions that are genetically related to the primary, while new primary lesions (mechanism c) are genetically distinct. Interestingly, recurrence/progression in IPMN displays conceptual parallels with the well-established paradigm of disease recurrence in patients with hepatocellular carcinoma (HCC). Specifically, patients with HCC may also develop recurrent tumors due to microscopic residual disease/intrahepatic metastasis which are genetically similar to the primary while the development of genetically unrelated, de novo HCC after curative-intent resection is also common. The latter has been attributed to the presence of a widespread genetic abnormality (“field defect”) in the liver (ie, cirrhosis). Given the conceptual similarities between IPMN and HCC, a pancreatic “field defect”may also be hypothesized to exist. This review does not suggest that HCC and IPMN have identical pathogeneses, but rather that they have conceptual similarities in tumor recurrence/progression; thus, lessons learned from HCC could be applied to IPMN research and subsequent management. Conceptual similarities in tumor progression and recurrence may also be observed between IPMN and other malignancies. However, HCC was selected because it is well studied and can serve as a paradigm.","PeriodicalId":92925,"journal":{"name":"Journal of pancreatology","volume":"5 1","pages":"36 - 40"},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44626312","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}

This study aimed to investigate the efficacy and safety of tegafur/gimeracil/oteracil (S-1)-based adjuvant concurrent chemoradiotherapy in resected PDAC patients with defined high-risk pathological features. Methods: We conducted a single-arm, prospective, and interventional study at Zhongshan Hospital Fudan University from December 2012 to December 2019 and the last follow-up was conducted in December 2021. This study was approved by the Ethics Committee of Zhongshan Hospital Fudan University on December 27, 2012 (approval No. B2012-139). Resected PDAC patients with high-risk pathological features, including positive resection margin, pathological T3-4N1-2M0 disease, peripancreatic fat invasion, microvascular invasion, and perineural invasion, were recruited. Primary endpoint was overall survival and secondary endpoints were disease-free survival, treatment toxicity, and 2-, 5-year survival rates. Results: A total of 54 patients were recruited. Mean age was 63.6 years old (±7.2). The distribution of T and N stages were 24.1% for T1, 46.3% for T2, 27.8% for T3, 1.9% for T4, 33.3% for N1, and 11.1% for N2. Seven patients had R1 resection. The median overall survival and disease-free survival were 27.1 and 13.7 months, respectively, while no fatal adverse events were recorded. Subgroup analyses showed differences in survival outcomes among patients with microvascular invasion, different N stages, and preoperative CA 19-9 levels. Further, a Cox proportional hazard model demonstrated associations of lymph node metastases, CA 19-9 level, and microvascular invasion with overall survival and disease-free survival.

We intend to investigate the risk and hospital outcomes of acute venous thromboembolisms (VTE) in patients with AP. Methods: We retrospectively analyzed patients with AP from 2016 to 2019 using the National Inpatient Sample database. Primary outcome was the effect of VTE on the length of stay, inpatient costs, and mortality. Hierarchical multivariate logistic regression models were built using univariate screens. Results: The study included 909,354 weighted discharges with AP. 2.1% of cases had an acute VTE. The length of stay was 5.9 days longer in the hospital of AP patients with VTE compared to AP with no VTE (P < 0.001). Total hospital charge per patient was $71,914 in patients with VTE compared to AP with no VTE (P < 0.001). Mortality was higher in AP patients with VTE compared to AP with no VTE (adjusted odds ratio [AOR] 4.2, 95% confidence interval [CI]: 3.4–5.3, P < 0.001). AP was associated with an increased VTE risk during inpatient stay (AOR 1.06, 95% CI 1.04–1.1, P < 0.001) There was an increased association of lower and upper extremity deep venous thrombosis with AP without necrosis (AOR 6.9, 95% CI 6.4–7.4, P < 0.001) and AP with infected necrosis (AOR 12.2, 95% CI 10.6–14.1, P < 0.001) but not in AP without necrosis (AOR 0.77, 95% CI 0.74–0.81, P < 0.001).
