Abstract
Pancreatic acinar cell carcinoma (PACC) is a rare type of pancreatic cancer; further, its pathogenesis and treatment strategies remain unclear. We report the case of a 70-year-old man who presented with a chief complaint of abdominal distention. Computed tomography scans revealed a large lobulated mass (tumor diameter: 150 mm) in the pancreatic body tail, which was diagnosed as a PACC through endoscopic ultrasonography fine needle aspiration. The other imaging modalities did not reveal distant metastases, and the tumor was classified as resectable. Neoadjuvant chemotherapy was planned after staging laparoscopy ruled out microscopic distant metastasis. First-line chemotherapy with gemcitabine + nab-paclitaxel failed due to tumor growth and worsening abdominal distention. Evaluation using the BRACAnalysis® device indicated that the patient was positive for BRCA1 mutation. Second-line modified FOLFIRINOX (mFFX) resulted in a marked decrease in elastase 1 levels; moreover, a partial antitumor response was observed, which prompted radical resection. After distal pancreatectomy, the patient has survived for 3.5 years without recurrence. BRCA-mutated pancreatic cancer is more likely to respond to mFFX, including platinum, and BRCA mutations have been reported to be highly prevalent in PACC. It is important to evaluate the presence of BRCA mutations in patients with PACC prior to treatment.

Abstract
BACKGROUND Glomus tumors (GT) generally occur in the skin. However, esophageal GT, an extremely rare condition, has no established standardized treatment guidelines. Herein, we report the case of an esophageal GT successfully removed by thoracoscopic enucleation in the prone position using intra-esophageal balloon compression. CASE PRESENTATION A 45-year-old man underwent an annual endoscopic examination and was found to have a submucosal tumor in the lower esophagus. Endoscopic ultrasound (EUS) revealed a hyperechoic mass originating from the muscular layer. Contrast-enhanced computed tomography identified a 2 cm mass lesion with high contrast enhancement in the right side of the lower esophagus. Pathologic findings of EUS-guided fine needle aspiration biopsy (EUS-FNA) revealed round to spindle shaped atypical cells without mitotic activity. Immunohistochemically, the tumor was positive for alpha-smooth muscle actin, but negative for CD34, desmin, keratin 18, S-100 protein, melan A, c-kit, and STAT6. He was diagnosed with an esophageal GT and a thoracoscopic approach to tumor resection was planned. Under general anesthesia, a Sengstaken-Blakemore (SB) tube was inserted into the esophagus. The patient was placed in the prone position and a right thoracoscopic approach was achieved. The esophagus around the tumor was mobilized and the SB tube balloon inflated to compress the tumor toward the thoracic cavity. The muscle layer was divided and the tumor was successfully enucleated without mucosal penetration. Oral intake was initiated on postoperative day (POD) 3 and the patient discharged on POD 9. No surgical complications or tumor metastasis were observed during the 1-year postoperative follow-up. CONCLUSIONS As malignancy criteria for esophageal GT are not yet established, the least invasive procedure for complete resection should be selected on a case-by-case basis. Thoracoscopic enucleation in the prone position using intra-esophageal balloon compression is useful to treat esophageal GT on the right side of the esophagus.

Abstract
The development of tumors in livers transplanted from hepatitis B virus (HBV)-negative donors to patients with hepatitis B and cirrhosis is rare. The present study describes the case of a woman in her 60s who developed hepatocellular carcinoma (HCC) in her grafted liver, 19 years after transplantation, as well as a metachronous colorectal tumor. The pathological findings, including clinical, immunohistochemical and molecular results, are described in the present case report. The liver tumor was a conventional HCC and the colorectal tumor comprised a tubular adenocarcinoma. Immunohistochemistry of both tumors showed a loss of expression of mutL homolog 1 and postmeiotic segregation increased 2 in the tumor cells, confirming microsatellite instability-high (MSI-H) status. Furthermore, a molecular study detected the presence of genes located on the Y chromosome in the normal and tumor tissues of the liver, proving that the HCC occurred in the grafted liver. The present report also discusses that prolonged use of immunosuppressive drugs to prevent post-transplant rejection, poorly controlled diabetes mellitus and MSI-H may have contributed to the risk of tumor development.

Novel choledochojejunostomy technique "T-shaped anastomosis" for preventing the development of postoperative cholangitis in pancreatoduodenectomy: A propensity score matching analysis. Ann Gastroenterol Surg 2024; 8:301-311. [PMID: 38455496 PMCID: PMC10914695 DOI: 10.1002/ags3.12744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 09/06/2023] [Accepted: 09/12/2023] [Indexed: 03/09/2024] Open
Abstract
Background There have been few studies of countermeasures against postoperative cholangitis, a serious complication after pancreaticoduodenectomy (PD) that impairs quality of life. Objective To evaluate our recently developed, novel method of choledochojejunostomy with a larger anastomotic diameter, the "T-shaped anastomosis." Methods The study included 261 cases of PD. The T-shaped choledochojejunostomy technique was performed with an additional incision for a distance greater than half the diameter of the bile duct at the anterior wall of the bile duct and the anterior wall of the elevated jejunum. To compensate for potential confounding biases between the standard anastomosis group (n = 206) and the T-shaped anastomosis group (n = 55), we performed propensity score matching (PSM). The primary endpoint was the incidence of medium-term postoperative cholangitis adjusted for PSM. Results In the PSM analysis, 54 patients in each group were matched, and the median bile duct diameter measured by preoperative CT was 8.8 mm versus 9.3 mm, the rate of preoperative biliary drainage was 31% versus 37%, the incidence of cholangitis within 1 month before surgery was 9% versus 13%, and the incidence of postoperative bile leakage was 2% versus 2%, with no significant differences. The incidence of medium-term postoperative cholangitis was 15% versus 4%, and multivariate logistic regression revealed that T-shaped choledochojejunostomy was an independent predictor of a reduced incidence of cholangitis (odds ratio, 0.17, 95% CI 0.02-0.81; p = 0.024). Conclusions The T-shaped choledochojejunostomy technique was shown to be effective with a significant reduction in the incidence of medium-term postoperative cholangitis.

Abstract
BACKGROUND Minimally invasive distal pancreatectomy (MIDP), including laparoscopic and robotic distal pancreatectomy, has gained widespread acceptance over the last decade owing to its favorable short-term outcomes. However, evidence regarding its oncologic safety is insufficient. In March 2023, a randomized phase III study was launched in Japan to confirm the non-inferiority of overall survival in patients with resectable pancreatic cancer undergoing MIDP compared with that of patients undergoing open distal pancreatectomy (ODP). METHODS This is a multi-institutional, randomized, phase III study. A total of 370 patients will be enrolled from 40 institutions within 4 years. The primary endpoint of this study is overall survival, and the secondary endpoints include relapse-free survival, proportion of patients undergoing radical resection, proportion of patients undergoing complete laparoscopic surgery, incidence of adverse surgical events, and length of postoperative hospital stay. Only a credentialed surgeon is eligible to perform both ODP and MIDP. All ODP and MIDP procedures will undergo centralized review using intraoperative photographs. The non-inferiority of MIDP to ODP in terms of overall survival will be statistically analyzed. Only if non-inferiority is confirmed will the analysis assess the superiority of MIDP over ODP. DISCUSSION If our study demonstrates the non-inferiority of MIDP in terms of overall survival, it would validate its short-term advantages and establish its long-term clinical efficacy. TRIAL REGISTRATION This trial is registered with the Japan Registry of Clinical Trials as jRCT 1,031,220,705 [ https://jrct.niph.go.jp/en-latest-detail/jRCT1031220705 ].

Evaluating staging laparoscopy indications for pancreatic cancer based on resectability classification and treatment strategies for patients with positive peritoneal washing cytology. Ann Gastroenterol Surg 2024; 8:124-132.

Abstract
Introduction The prognosis of pancreatic ductal adenocarcinoma (PDAC) in patients with positive peritoneal washing cytology (CY1) is poor. We aimed to evaluate the results of staging laparoscopy (SL) and treatment efficacy in CY1 patients based on a resectability classification. Methods We retrospectively reviewed 250 patients with PDAC who underwent SL before the initial treatment between 2017 and 2023 at the University of Toyama. Results The breakdown of cases by resectability classification was resectable (R):borderline resectable (BR):unresectable locally advanced (UR-LA) = 131:48:71 cases. The frequency of CY1 increased in proportion to the degree of local progression (R:BR:UR-LA = 20:23:34%), but the frequencies of liver metastasis or peritoneal dissemination were comparable (R:BR:UR-LA = 6.9:6.3:8.5%). Most CY1 patients received gemcitabine along with nab-paclitaxel therapy. The CY-negative conversion rates (R:BR:UR-LA = 70:64:52%) and conversion surgery rates (R:BR:UR-LA = 40:27:9%) were inversely proportional to the degree of local progression.Comparing H0P0CY1 factors for each classification, patients with H0P0CY1 had significantly more pancreatic body or tail carcinoma and tumor size ≥32 mm in R patients, whereas in BR patients, duke pancreatic monoclonal antigen type 2 (DUPAN-2) ≥ 230 U/mL was a significant factor. In contrast, no significant factors were observed in UR-LA patients. Conclusion The CY1 rates, CY-negative conversion rates, and conversion surgery rates varied according to local progression. In the case of R and BR, SL could be considered in patients with pancreatic body or tail carcinoma, large tumor size, or high DUPAN-2 level. In UR-LA, SL might be considered for all patients.

Abstract
BACKGROUND The frequency and prognosis of positive peritoneal washing cytology (CY1) in resectable pancreatic ductal adenocarcinoma (R-PDAC) remains unclear. The objective of this study was to identify the clinical implications of CY1 in R-PDAC and staging laparoscopy (SL). METHODS We retrospectively analyzed 115 consecutive patients with R-PDAC who underwent SL between 2018 and 2022. Patients with negative cytology (CY0) received radical surgery after neoadjuvant chemotherapy, while CY1 patients received systemic chemotherapy and were continuously evaluated for cytology. RESULTS Of the 115 patients, 84 had no distant metastatic factors, 22 had only CY1, and nine had distant metastasis. Multivariate logistic regression revealed that larger tumor size was an independent predictor of the presence of any distant metastatic factor (OR: 6.30, p = .002). Patients with CY1 showed a significantly better prognosis than patients with distant metastasis (MST: 24.6 vs. 18.9 months, p = .040). A total of 11 CY1 patients were successfully converted to CY-negative, and seven underwent conversion surgery. There was no significant difference in overall survival between patients with CY0 and those converted to CY-negative. CONCLUSION SL is effective even for R-PDAC. The prognosis of CY1 patients converted to CY-negative is expected to be similar to that of CY0 patients.

Abstract
Background Nab-paclitaxel plus gemcitabine is a standard treatment for metastatic/locally advanced pancreatic cancer. The effectiveness of neoadjuvant therapy with nab-paclitaxel plus gemcitabine (GnP-NAT) in patients with borderline resectable pancreatic cancer (BRPC) remains unclear. Patients and Methods This single-arm phase II trial included 61 patients with BRPC that were treated with two cycles of GnP-NAT, (nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2), on days 1, 8, and 15 over a 4-week period, which comprised one cycle. The primary endpoint was overall survival time. In the absence of disease progression, patients underwent planned pancreatectomy. Results Median overall survival, the primary endpoint, was 25.2 months, and the median recurrence-free survival was 12.3 months. The overall rate of grade 3/4 events was 73.8%. One patient, who had a history of radiation therapy for past esophageal cancer, died from exacerbation via pneumonia. The overall resection rate was 73.8% (n = 45), and the R0 resection rate was 63.9% (n = 39). Overall, postoperative complications were found in 19 patients (42%) with 24 events, and nine patients (20%) with nine events ≥ grade IIIa, based on Dindo's classification. Conclusions This protocol treatment is thought to be a feasible, safe, and promising treatment regimen, but we caution against its use in patients with a history of interstitial lung disease and/or prior pulmonary irradiation. The survival data from this study suggest the need for further investigations of GnP-NAT efficacy in patients with BRPC, as well as prospective evaluation of adverse events.

Abstract
OBJECTIVES COVID-19 vaccine hesitancy/fatigue is increasing as the pandemic enters the endemic phase. The present study aimed to explore current perceptions about COVID-19 booster vaccination among the Japanese public. STUDY DESIGN This was a cross-sectional study. METHODS This cross-sectional study used data from the Japan COVID-19 and Society Internet Survey conducted in September 2021 and September 2022. The public's perceptions of COVID-19 vaccination and factors associated with COVID-19 booster vaccine hesitancy were analyzed. RESULTS In total, 56,735 respondents were included. In the Japan COVID-19 and Society Internet Survey 2021, 75.1% of the participants (21,126/28,118) had completed the primary vaccination series. In the 2022 survey, 74.1% of the respondents (21,216/28,617) completed the primary series of vaccination with booster doses. The proportion of fear toward COVID-19 and obtaining information about COVID-19 has decreased from 2021 to 2022. Factors independently associated with booster vaccine hesitancy were young age (range: 18-29 years; adjusted odds ratio [aOR]: 6.56), history of COVID-19 (aOR: 1.82), distrust of the Japanese government's COVID-19 prevention measures (aOR: 1.55), lack of confidence in COVID-19 vaccine efficacy (aOR: 1.30), lack of confidence in COVID-19 vaccine safety (aOR: 1.62), low reliance on the COVID-19 vaccine (aOR: 1.92), and belief in COVID-19 conspiracy theories (aOR: 1.77). CONCLUSIONS Providing clear and trustworthy information is critically important, especially targeted and tailored messages for the young generation, to promoting COVID-19 booster vaccination. Policymakers should therefore develop consistent and transparent communication strategies and the ability to respond promptly and flexibly to mitigate the negative impact of COVID-19 on the public while preparing for the next pandemic.

Abstract
We present the case of a 100-year-old man with no specific symptoms. Computed tomography (CT) revealed a 34 mm tumor in the pancreatic tail, which was diagnosed as pancreatic cancer by biopsy. CT and magnetic resonance imaging showed that the tumor was resectable, and there were no noncurative factors on staging laparoscopy (cT3N0M0: cStage IIA). His performance status was good, and hypertension was the only comorbidity. A cardiologist, respiratory physician, and anesthesiologist examined the patient and determined that his condition was suitable for surgery. His postoperative predicted mortality rate was 0.9% using the American College of Surgeons risk calculator. We administered synbiotics and nutrients before surgery and introduced preoperative rehabilitation to improve his activities of daily living (ADL) as well as respiratory training to prevent postoperative pneumonia. Regarding the invasiveness of the surgery, we performed laparoscopic distal pancreatectomy with D1 lymphadenectomy. The patient was discharged on postoperative day 17, without any major complications. When performing pancreatectomy in older adults, it is important to fully assess preoperative tolerance and perioperative risk and prevent worsening of ADL by introducing nutritional therapy and rehabilitation.

Abstract
PURPOSE The efficiency and safety of routine intravenous administration of acetaminophen after highly invasive hepatobiliary pancreatic surgery remain unclear. In particular, there have been no studies focusing on pancreatoduodenectomy. The present study clarified its clinical utility for patients undergoing pancreatoduodenectomy. METHODS We retrospectively collected 179 patients who underwent open pancreatoduodenectomy from 2015 to 2020. The analgesic effects and adverse events in patients with scheduled intravenous administration of acetaminophen were evaluated using propensity score matching. RESULTS After 40 patients from each group were selected by propensity score matching, the postoperative liver function tests were not significantly different between the control and acetaminophen groups. No significant differences were found in the self-reported pain intensity score or postoperative nausea and vomiting; however, the rate of pentazocine use and the total number of additional analgesics were significantly lower in the acetaminophen group than in the control group (p = 0.003 and 0.002, respectively). CONCLUSION The scheduled intravenous administration of acetaminophen did not affect the postoperative liver function and had a good analgesic effect after pancreatoduodenectomy.

Abstract
BACKGROUND Squamous cell carcinoma (SCC) of the breast is a rare form of breast cancer, accounting for approximately 0.1% of all breast cancers. It is known for its rapid tumor growth and poor prognosis with no established treatment. CASE PRESENTATION A 56-year-old woman was diagnosed with breast SCC with axillary, supraclavicular and internal thoracic lymph node metastases. She received neoadjuvant chemotherapy (NAC) with dose-dense doxorubicin and cyclophosphamide (AC) followed by dose-dense paclitaxel (PTX). This treatment resulted in a pathological complete response (pCR) after breast-conserving surgery. The patient was then treated with radiotherapy. She remained free of recurrence for three years postoperatively. CONCLUSIONS We report a rare case of breast SCC treated with preoperative dose-dense chemotherapy, resulting in pCR and allowing breast-conserving surgery.

Abstract
Despite recent advances in multidisciplinary treatments of esophageal squamous cell carcinoma (ESCC), patients frequently suffer from distant metastasis after surgery. For numerous types of cancer, circulating tumor cells (CTCs) are considered predictors of distant metastasis, therapeutic response and prognosis. However, as more markers of cytopathological heterogeneity are discovered, the overall detection process for the expression of these markers in CTCs becomes increasingly complex and time consuming. In the present study, the use of a convolutional neural network (CNN)-based artificial intelligence (AI) for CTC detection was assessed using KYSE ESCC cell lines and blood samples from patients with ESCC. The AI algorithm distinguished KYSE cells from peripheral blood-derived mononuclear cells (PBMCs) from healthy volunteers, accompanied with epithelial cell adhesion molecule (EpCAM) and nuclear DAPI staining, with an accuracy of >99.8% when the AI was trained on the same KYSE cell line. In addition, AI trained on KYSE520 distinguished KYSE30 from PBMCs with an accuracy of 99.8%, despite the marked differences in EpCAM expression between the two KYSE cell lines. The average accuracy of distinguishing KYSE cells from PBMCs for the AI and four researchers was 100 and 91.8%, respectively (P=0.011). The average time to complete cell classification for 100 images by the AI and researchers was 0.74 and 630.4 sec, respectively (P=0.012). The average number of EpCAM-positive/DAPI-positive cells detected in blood samples by the AI was 44.5 over 10 patients with ESCC and 2.4 over 5 healthy volunteers (P=0.019). These results indicated that the CNN-based image processing algorithm for CTC detection provides a higher accuracy and shorter analysis time compared to humans, suggesting its applicability for clinical use in patients with ESCC. Moreover, the finding that AI accurately identified even EpCAM-negative KYSEs suggested that the AI algorithm may distinguish CTCs based on as yet unknown features, independent of known marker expression.

Abstract
BACKGROUND The pectoralis major musculocutaneous flap (PMMF) is a pedicled flap often used as a reconstruction option in head and neck surgery, especially in cases with poor wound healing. However, applying PMMF after esophageal surgery is uncommon. We report here, the case of a successfully repaired refractory anastomotic fistula (RF) after total esophagectomy, by PMMF. CASE PRESENTATION A 73-year-old man had a history of hypopharyngolaryngectomy, cervical esophagectomy, and reconstruction using a free jejunal graft for hypopharyngeal carcinosarcoma at the age of 54. He also received conservative treatment for pharyngo-jejunal anastomotic leakage (AL), then postoperative radiation therapy. This time, he was diagnosed with carcinosarcoma in the upper thoracic esophagus; cT3rN0M0, cStageII, according to the Japanese Classification of Esophageal Cancer 12th Edition. As a salvage surgery, thoracoscopic total resection of the esophageal remnant and reconstruction using gastric tube via posterior mediastinal route was performed. The distal side of the jejunal graft was cut and re-anastomosed with the top of the gastric tube. An AL was observed on the 6th postoperative day (POD), and after 2 months of conservative treatment was then diagnosed as RF. The 3/4 circumference of the anterior wall of the gastric tube was ruptured for 6 cm in length, and surgical repair using PMMF was performed on POD71. The edge of the defect was exposed and the PMMF (10 × 5 cm) fed by thoracoacromial vessels was prepared. Then, the skin of the flap and the wedge of the leakage were hand sutured via double layers with the skin of the flap facing the intestinal lumen. Although a minor AL was observed on POD19, it healed with conservative treatment. No complications, such as stenosis, reflux, re-leakage, were observed over 3 years of postoperative follow-up. CONCLUSIONS The PMMF is a useful option for repairing intractable AL after esophagectomy, especially in cases with large defect, as well as difficulties for microvascular anastomosis due to previous operation, radiation, or wound inflammation.

Abstract
541 Background: Relapse after highly invasive surgery for biliary tract cancers (BTCs), especially in the early postoperative period, causes medical, psychological, social, and economic disadvantages to the patients. However, approximately 30% of patients with curatively resected BTCs experience relapse within the first 12 months. JCOG1202 (UMIN000011688) is a randomized phase III trial conducted in patients with resected BTCs showing the benefit of adjuvant S-1 for overall survival. This study aimed to investigate the risk factors for early relapse of resected BTCs in the JCOG1202 cohort. Methods: Of the 440 patients enrolled in the JCOG1202, 217 patients who received surgery alone (arm A) and 207 patients who received adjuvant S-1 (arm B) were eligible and included in this analysis. Early relapse was defined as relapse or death within 12 months after enrollment. Predictive factors for early relapse were assessed using logistic regression analyses. Results: Postoperative early relapse was observed in 59 (27.2%) and 38 (18.4%) of patients in arm A and arm B, respectively. In multivariable logistic regression analysis for the 424 eligible patients, postoperative CA19-9 levels >37 u/ml (odds ratio (OR): 2.790, 95% confidence interval (CI): 1.262-6.170), poorly differentiation (vs. well-differentiated/papillary) (OR: 4.746, 95% CI:1.927-11.688), moderate differentiation (vs. well-differentiated/papillary) (OR: 1.955, 95% CI:1.071-3.567), lymph node metastases > 4 (vs. 0) (OR: 3.991, 95% CI: 1.674-9.514), lymph node metastases 1-3 (vs. 0) (OR: 2.661, 95% CI: 1.471-4.814), and presence of residual tumor (OR: 2.171, 95% CI: 1.070-4.408) were independent risk factors for early relapse. Importantly, adjuvant S-1 chemotherapy significantly reduced early relapse (OR: 0.491, 95% CI: 0.290-0.833). Similar results were observed in arm B. Conclusions: Postoperative CA19-9 level, tumor differentiation, lymph node metastases, and the residual tumor significantly impact early relapse in patients with curatively resected BTCs. Although adjuvant S-1 chemotherapy was effective in reducing early relapse, similar factors tended to be the risk factors in patients receiving adjuvant S-1 chemotherapy. Patients at high risk of early relapse may need more intensive perioperative therapy. Clinical trial information: UMIN000011688 .

Abstract
745 Background: Serum CA125 is a potential biomarker for diagnosis of peritoneal metastasis in gastric cancer. However, its significance of pancreatic cancer (PC) has not been investigated. Therefore, we aimed to clarify association between serum CA125 and ascites burden, and its kinetics during first-line chemotherapy for PC. Methods: This multicenter retrospective study comprised PC patients who received FOLFIRINOX or gemcitabine plus nab-paclitaxel in first-line setting between Jan 2014 and Dec 2021. Patient background and treatment outcome was assessed in CA125 elevated and non-elevated group before chemotherapy. The CA125 kinetics after chemotherapy was calculated based on baseline and first measure of CA125. Further, the association between early CA125 change and clinical response during chemotherapy were evaluated based on optimal cut off value calculated receiver operating characteristic (ROC) curve analysis. Results: A total 109 patients from 3 hospitals were assessable. The overall survival (OS) was significantly shorter in elevated group than that in non-elevated group (median, 10.7 vs. 21.3 months, p = 0.0002). The median value of CA125 before chemotherapy was elevated according to ascites burden (Non, 36U/ml; mild, 173U/ml; moderate/severe, 575U/ml; p < 0.0001). CA125 elevation, CA19-9 elevation, poor performance status and poor glasgow prognostic score were independent prognostic factors in multivariate analysis. After chemotherapy, the median first-time measure of CA125 was performed in day 41. Among patients with peritoneal dissemination, the median change of CA125 was correlated with clinical response (CR/PR, -0.55%/day; SD, -0.24%/day; PD, 3.35%/day, p = 0.004). After chemotherapy, first-time measure of CA125 was performed in a median of day 41. According to the ROC curve analysis, the optimal cut-off value of increase in CA125 for progressive disease was 1.56 %/day (specificity 94.1%, sensitivity 80%). The median PFS and OS were 1.4 and 6.6 months in increased group and 3.3 months and 14.0 months in non-increased group, respectively (p = 0.016 and p = 0.028). Conclusions: CA125 is considered a clinically useful marker in unresectable PC treated with first-line chemotherapy because CA125 above the ULN is a poor prognostic factor for OS and an increased CA125 can be an early predictor of progression in patients with peritoneal dissemination.

Abstract
674 Background: Positive peritoneal cytology has been reported to indicate a poor prognosis in patients with pancreatic cancer even if the primary tumor is surgically resected. This study investigated the clinical implications of peritoneal cytology by staging laparoscopy for patients with potentially resectable pancreatic cancer for whom initial treatment will be started. Methods: We retrospectively reviewed 113 consecutive patients with pancreatic cancer diagnosed as resectable by computed tomography in whom peritoneal cytology was evaluated by staging laparoscopy between December 2018 and August 2022. Patients with positive cytology received induction chemotherapy, and those in whom cytology converted to negative underwent surgical resection as needed when possible. We set best tumor marker cutoff values for predicting positive cytology by maximizing the Youden index. Results: Seventy-three patients were men and the mean age was 72 years. Thirty patients (26.5%) had positive cytology at initial staging laparoscopy. Minimal peritoneal metastases were detected in seven of these patients and liver metastases in two. Larger tumor diameter ( > 30 mm), location in the pancreatic body or tail, an elevated CA19-9 level ( > 138.5 U/ml), an elevated CA125 level ( > 13.5 U/ml), and an elevated CEA level ( > 5.1 ng/ml) were associated with a significantly increased risk of positive cytology (odds ratio 4.71 [confidence interval 1.87–12.2] P = 0.001, 2.49 [1.07–6.05] P = 0.038, 2.95 [1.26–7.12] P = 0.014, 3.89 [1.57-10.7] P = 0.005, and 3.52 [1.23–10.2] P = 0.018, respectively). Eighteen patients (60%) who received induction chemotherapy converted from positive to negative cytology; seven (38%) of these patients underwent surgery and all remain alive without recurrence. Interestingly, median overall survival in patients with negative cytology was not necessarily inferior to that in those with positive cytology (23.4 months vs. 24.2 months, P = 0.33). Conclusions: Over a quarter of patients with pancreatic cancer that is diagnosed as resectable by computed tomography may have positive peritoneal cytology at the initial assessment. These patients tend to have higher CA19-9, CA125, and CEA levels, larger tumors, and tumors located in the body or tail of the pancreas. A more favorable prognosis may be achieved by administering induction chemotherapy until cytology converts to negative than by upfront surgery.

Abstract
680 Background: Multidisciplinary treatment of borderline resectable (BR)/unresectable locally advanced (UR-LA) pancreatic adenocarcinoma (PDAC) has not yet been established. The purpose of this study is to explore factors that improve prognosis in radical surgery after multidisciplinary treatment for pancreatic cancer. Methods: We evaluated the following prognostic factors in 240 PDAC patients who underwent radical resection after multidisciplinary treatment. Patients were classified into 3 groups according to NCCN guidelines (BR PDAC invading the portal vein (BR-PV), BR pancreatic cancer in contact with the major arteries such as the hepatic artery, celiac axis and superior mesenteric artery (BR-A), and UR-LA), and prognostic factors were investigated. Patients with BR PDAC were treated with chemotherapy followed by surgery, while radiation therapy was added preoperatively in most cases with arterial invasion. All patients with UR-LA underwent surgery after nab-paclitaxel plus gemcitabine (GnP) followed by chemoradiotherapy (CRT) with S-1. Results: BR-PV/BR-A/UR-LA patients were 88/111/41, respectively. Prognosis was significantly better in the NAT group than in the upfront surgery group for both BR-PV/A (P=0.004/<0.001). In univariate analysis of overall survival (OS) in 36 patients with BR-PV who underwent resection after NAT, the following factors were significantly favorable prognostic factors; tumor marker (TM) normalization (P=0.028), preoperative Glasgow prognostic score=0 (P=0.025), and preoperative prognostic nutritional index (PNI)>42.5 (P=0.022). In univariate analysis in 39 patients with BR-A, the following factors were significantly favorable prognostic factors; TM normalization (P=0.033), preoperative PNI>42.5 (P=0.013), intraoperative blood loss>830 ml (P=0.013). Multivariate analysis revealed that high preoperative PNI was an independent prognostic factor (hazard ratio 0.15 [0.02-0.85]; P=0.014) in BR-A patients. In patients with UR-LA who underwent radical resection after GnP and subsequent CRT, median duration of NAT was 8.8 months, and R0 resection was achieved in 36 patients (88%). 3-year OS was 77.4%, and 5-year OS 58.6%. Multivariate analysis revealed that CA19-9 normalization (hazard ratio 0.23 [0.02-0.88]; P=0.032) and PNI≥41.7 (HR 0.05 [0.01-0.62]; P=0.021) were independent prognostic factors. Conclusions: In both BR/UR-LA pancreatic cancer, normalization of TM and maintenance of good nutritional status during NAT until surgery may contribute to prolonged prognosis.

Abstract
BACKGROUND/AIM MicroRNAs (miRNAs) are abnormally expressed and involved in the pathogenesis of various carcinomas. The present study aimed to identify novel miRNA genes associated with the pathogenesis and prognosis of oesophageal squamous cell carcinoma (ESCC). MATERIALS AND METHODS The miRNA profiling of 873 genes was performed using surgically resected oesophageal tissues from 35 patients with ESCC to identify candidate miRNAs. To examine the biological activities of candidate miRNAs, their proliferative, invasive, and migratory abilities were evaluated in ESCC cells subjected to miRNA mimic-mediated over-expression. The miRNA expression levels of the selected candidate miRNAs were analysed in the resected oesophageal tissues of 76 patients with ESCC from the two cohorts and correlated with the clinicopathological parameters. RESULTS Among the four candidate miRNAs identified by miRNA profiling, miR-877-3p was selected for subsequent analyses. In vitro analyses showed that the over-expression of miR-877-3p significantly suppressed the proliferation, invasion, and migration of ESCC cell lines compared with those of control cells. In the analyses of clinical specimens, the expression of miR-877-3p was down-regulated in ESCC tissues compared with that in adjacent normal oesophageal tissues. The down-regulation of miR-877-3p expression in ESCC tissues was significantly associated with advanced local progression and lymphatic involvement. The miR-877-3p down-regulation was also significantly associated with poor disease-free and disease-specific survival. CONCLUSION miR-877-3p acts as a tumour suppressor gene in ESCC cells, and its down-regulation in ESCC tissues is associated with a poor prognosis. Thus, miR-877-3p may serve as a novel prognostic marker and promising therapeutic target.

Abstract
Background Local duodenectomy and primary closure is a simple option for some nonampullary duodenal neoplasms. Minimizing the resection area while ensuring curability is necessary for safe primary duodenal closure. However, it is often difficult to determine the appropriate resection line from the serosal side. We developed clip-guided local duodenectomy to easily determine the resection range and perform local duodenectomy safely, then performed a retrospective observational study to confirm the safety of clip-guided local duodenectomy. Methods The procedure is as follows: placing endoscopic metal clips at four points on the margin around the tumor within 3 days before surgery, identifying the tumor extent with the clips under X-ray imaging during surgery, making an incision to the duodenum just outside of the clips visualized by X-ray imaging, full-thickness resection of the duodenum with the clips as guides of tumor demarcation, and transversely closure by Gambee suture. We evaluated clinicopathological data and surgical outcomes of patients who underwent clip-guided local duodenectomy at two surgical centers between January 2010 and May 2020. Results Eighteen patients were included. The pathological diagnosis was adenoma (11 cases), adenocarcinoma (6 cases), and GIST (1 case). The mean ± SD tumor size was 18 ± 6 mm, and the tumor was mainly located in the second portion of the duodenum (66%). In all cases, the duodenal defect was closed with primary sutures. The mean operation time and blood loss were 191 min and 79 mL, respectively. The morbidity was 22%, and all complications were Clavien–Dindo grade II. No anastomotic leakage or stenosis was observed. In the 6 adenocarcinoma patients, all were diagnosed with pT1a, and postoperative recurrence was not observed. The 1-year overall and recurrence free survival rate was 100%. Conclusions Clip-guided local duodenectomy is a safe and useful surgical option for minimally local resection of nonampullary duodenal neoplasms such as duodenal adenoma, GIST, and early adenocarcinoma.

Abstract
Background In pancreatic ductal adenocarcinoma (PDAC), only radical surgery improves long-term survival. We focused on surgical outcome after induction gemcitabine along with nab-paclitaxel (GnP) and subsequent chemoradiotherapy (CRT) with S-1 administration for unresectable locally advanced (UR-LA) PDAC. Methods We retrospectively analyzed 144 patients with UR-LA PDAC between 2014 and 2020. The first-line regimen of induction chemotherapy was GnP for 125 of the 144 patients. Of the 125 patients who received GnP, 41 who underwent radical resection after additional preoperative CRT were enrolled. We evaluated the prognostic factors for this treatment strategy. Results The median length of preoperative GnP was 8.8 months, and 30 (73%) patients had normalized CA19-9 levels. R0 resection was achieved in 36 (88%) patients. Postoperative major complications of ≥Clavien-Dindo grade IIIa developed in 16 (39%) patients. With a median follow-up of 35.2 months, 14 (34%) patients developed distant metastasis postoperatively. Using the Kaplan-Meier method, prognostic analysis of the 41 cases revealed the 3-y overall survival rate (OS) was 77.4% and the 5-y OS was 58.6%. In univariate analysis, length of preoperative GnP (≥8 months), CA19-9 normalization, and good nutritional status at operation (prognostic nutritional index ≥41.7) were significantly associated with favorable prognosis. Multivariate analysis revealed CA19-9 normalization (hazard ratio [HR] 0.23; P = .032) and prognostic nutritional index ≥41.7 (HR 0.05; P = .021) were independent prognostic factors. Conclusion For surgical outcome after induction GnP and subsequent CRT for UR-LA PDAC, CA19-9 normalization and maintenance of good nutritional status during treatment until surgery were important for prolonged prognosis.

Abstract
BACKGROUND Pancreatic intraductal papillary mucinous neoplasm (IPMN) involves multiple histopathological stages from benign to malignant lesions. Further, a biomarker to diagnose the malignant IPMN (IPMC) is clinically relevant. Recently, we found that serum fucosylated α1 -acid glycoprotein (fAGP) level markedly elevated along with disease progression in large cohorts of patients with various cancers. METHODS The fAGP level was retrospectively analyzed in preoperative sera from 109 patients with IPMN, and the clinical relevance of fAGP was compared with currently available predictors as standard. RESULTS The fAGP level in IPMC was found to be significantly higher than in benign IPMN (P=0.0012). At a cutoff value of 27.04 U/μg, its sensitivity, specificity, and accuracy for IPMC were determined to be 83.61, 65.96 and 75.93%, respectively. Multivariate analyses revealed that the fAGP level was the only independent risk factor for predicting IPMC. Additionally, a combination of the fAGP level and 18 F-fluorodeoxyglucose uptake on the PET/CT imaging in the lesions seemed to offer the best diagnosis of IPMN. Accordingly, 27 of the 28 patients who were positive in both tests had IPMC, while patients who are negative had benign IPMN. CONCLUSIONS The fAGP level appeared to be a relevant biomarker for malignant potential of IPMN.
