Abstract
BACKGROUND The relationship between the course of the segment 4 hepatic artery and proximal ductal margin status in the right hepatectomy (H15678-B) for perihilar cholangiocarcinoma is unclear. This study aimed to evaluate proximal ductal margin status according to the course of the segment 4 hepatic artery in patients with perihilar cholangiocarcinoma treated with right hepatectomy. METHODS Consecutive patients with perihilar cholangiocarcinoma who underwent a right hepatectomy between January 2006 and August 2021 were retrospectively reviewed. The course of the segment 4 hepatic artery was classified based on the positional relationship with the umbilical portion of the left portal vein into R-UP and L-UP types. The R-UP type had the segment 4 hepatic artery running along the right caudal position of the umbilical portion of the left portal vein, whereas the L-UP type had the segment 4 hepatic artery running along the left cranial position of the umbilical portion of the left portal vein, with or without another branch running along the right caudal position of the umbilical portion of the left portal vein. Proximal ductal margin status after the right hepatectomy was compared between types. RESULTS Among 102 patients, 72 (70.5%) were R-UP type, and 30 (29.5%) were L-UP type. Rates of negative proximal ductal margin were higher with the L-UP type (27/30, 90.0%) than with the R-UP type (51/72, 70.8%; P = .04). On multivariate analysis, Bismuth-Corlette type II and IIIa (risk ratio 4.13, 95% confidence interval 1.52-11.5; P = .005) and L-UP type (risk ratio 4.03, 95% confidence interval 1.18-18.8; P = .04) were independent predictors of negative proximal ductal margin after a right hepatectomy for perihilar cholangiocarcinoma. CONCLUSION For the course of the segment 4 hepatic artery, L-UP type rather than R-UP type might be anatomically advantageous for achieving negative proximal ductal margin in a right hepatectomy for perihilar cholangiocarcinoma.

Abstract
BACKGROUND Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer. Cases when found are often advanced with vascular invasion, and radical resection is often difficult. Despite curative resection, the postoperative recurrence rate of patients with histological lymph node metastasis is high, and their prognosis is poor. Therefore, there is an urgent need to establish multidisciplinary treatment that combines chemotherapy and surgical resection. The efficacy of neoadjuvant chemotherapy (NAC) for locally advanced ICC is unclear. In this report, a case of locally advanced ICC in which pathological complete response (pCR) was achieved after NAC is described. CASE PRESENTATION A 79-year-old woman was admitted to a local hospital with appetite loss. Computed tomography showed a 100 × 90 mm low-contrast tumor in the left hepatic lobe and segment 1 with invasion to the inferior vena cava (IVC), and several lymph nodes along the left gastric artery and lesser curvature were enlarged. Therefore, she was treated with a combined chemotherapy regimen of gemcitabine and cisplatin. After four courses, the tumor size decreased to 30 × 60 mm without invasion to the IVC. Left hepatectomy extending to segment 1 with bile duct resection combined with middle hepatic vein resection (H1234-B-MHV), dissection of regional lymph nodes and pyloroplasty were performed. After radical resection, pCR was achieved. She is alive with no evidence of disease, 2 years after surgery. CONCLUSIONS In this case, a patient with locally advanced ICC achieved pCR to NAC. NAC may be effective for ICC. Patients who achieve pCR may have a better prognosis.

Abstract
BACKGROUND The indication for surgical resection of intraductal papillary mucinous neoplasms (IPMNs) is defined by imaging features, such as mural nodules. Although carbohydrate antigen (CA) 19-9 was selected as a parameter for worrisome features, no serum biomarkers were considered when deciding on surgical indications in the latest international consensus guideline. In this study, we assessed whether clinical factors, imaging findings, and serum biomarkers are useful in predicting malignant IPMNs. METHODS A total of 234 resected IPMN cases in Chiba University Hospital from July 2005 to December 2021 were retrospectively analyzed. RESULTS Among the 234 patients with resected IPMNs diagnosed by preoperative imaging, 117 were diagnosed with malignant pathologies (high-grade dysplasia and invasive IPMNs) according to the histological classification. In the multivariate analysis, cyst diameter ≥30 mm; p = 0.035), enhancing mural nodules on multidetector computed tomography (≥5 mm; p = 0.018), and high serum elastase-1 (≥230 ng/dl; p = 0.0007) were identified as independent malignant predictors, while CA19-9 was not. Furthermore, based on the receiver operator characteristic curve analyses, elastase-1 was superior to CA19-9 for predicting malignant IPMNs. Additionally, high serum elastase-1 levels (≥230 ng/dl; p = 0.0093) were identified as independent predictors of malignant IPMNs in patients without mural nodules on multidetector computed tomography (MDCT) in multivariate analysis. CONCLUSION The serum elastase-1 level was found to be a potentially useful biomarker for predicting malignant IPMNs.

Abstract
PURPOSE Systemic chemotherapy is generally used for metastatic pancreatic cancer; however, pulmonary resection may be a treatment option for lung oligometastases from pancreatic cancer. The current study aimed to clarify the oncological outcomes and clinical benefits of pulmonary resection for lung metastases. METHODS Of 510 patients who underwent pancreatic resection for pancreatic cancer, 44 patients with recurrence of isolated lung metastases and one patient with simultaneous lung metastases were evaluated. RESULTS Of the 45 patients, 20 patients were selected as candidates for pulmonary resection based on clinical factors such as recurrence-free interval (RFI) from pancreatectomy to lung metastases, number of lung metastases, and serum CA19-9 level. The post-recurrent survival of patients with pulmonary resection was significantly better than that of patients without pulmonary resection. Fourteen of the 20 patients with pulmonary resection developed tumor recurrence with a median disease-free survival (DFS) of 15 months. Univariate analyses revealed that an RFI from pancreatectomy to lung metastases of ≥28 months was associated with better DFS after pulmonary resection. Of the 14 patients with an RFI of ≥28 months, pulmonary resection resulted in prolonged chemotherapy-free interval in 12 patients. Furthermore, repeat pulmonary resection for recurrent tumors after pulmonary resection led to further cancer-free interval in some cases. CONCLUSIONS Although many patients had tumor recurrence after pulmonary resection, pulmonary resection for lung metastases from pancreatic cancer may provide prolonged cancer-free interval without the need for chemotherapy. Pulmonary resection should be performed for the patients with a long RFI from pancreatectomy to lung metastases.

Abstract
A 73-year-old female was diagnosed with gallbladder cancer, but the future liver remnant volume was deemed insufficient for curative resection. Consequently, transileocolic portal vein embolization was performed. During laparotomy, multiple nodules were palpable on the peritoneal surface of the pelvic floor. Subsequently, staging laparoscopy confirmed the pathological diagnosis of adenocarcinoma in the resected nodules, indicating peritoneal dissemination of gall bladder cancer. Due to this peritoneal dissemination, surgical resection was deemed inappropriate, and the patient was initiated on systemic chemotherapy consisting of gemcitabine and cisplatin. Following 22 courses of chemotherapy, contrast-enhanced computed tomography demonstrated no significant changes in the size of the primary tumor or its location relative to the main vessels, although a small metastatic lesion was identified in the gallbladder bed. At the second staging laparoscopy, any nodules suggesting peritoneal dissemination were observed. Based on these findings, we decided to perform curative resection. The surgical procedure involved right hepatectomy plus segment 4a resection, extrahepatic bile duct resection, and hepaticojejunostomy. Pathological examination revealed ypT3bN0M1(HEP), ypStage ⅣB, with the achievement of R0 resection. The patient survived with no recurrences for 40 months after surgery. These results suggest that aggressive therapeutic strategies, including conversion surgery following systemic chemotherapy, may be beneficial for patients initially deemed unresectable due to gallbladder cancer.

Abstract
Serial pancreatic juice aspiration cytological examination(SPACE)has been reported as a reliable preoperative diagnostic method for early pancreatic cancer, when combined with imaging findings suspecting early pancreatic cancer. Among 259 patients with suspected pancreatic cancer who underwent pancreatic resection at our hospital, SPACE was preoperatively performed in 14 cases(5.4%). Of these 14 cases, final pathological diagnosis was pancreatic cancer in 12 patients (86%), including 5 patients with Stage ⅠA pancreatic cancer(35.7%), all of whom had a mass on preoperative CT or EUS. On the other hand, in the other 2 cases(14.3%), CT/EUS detected no mass but focal pancreatic parenchymal atrophy and main pancreatic duct stenosis which were the imaging findings suspecting very early pancreatic cancer such as cancer in situ. Although preoperative SPACE results of these 2 cases were class Ⅳ, final pathological results of resected specimen were low-grade PanIN in both cases. SPACE was considered useful for preoperative diagnosis of pancreatic cancer in our study, however further study is needed to examine its diagnostic accuracy for early pancreatic cancer which does not appear as a mass in any imaging modality.

Abstract
Mucinous cystic neoplasm (MCN) is a premalignant cystic tumor of the pancreas. Resection of MCN in the distal pancreas is a standard treatment; however, at present, there is no consensus on the necessity or extent of lymph node dissection, and minimally invasive pancreatectomy is commonly the preferred surgical technique. Thus, the present study aimed to assess the efficacy of minimally invasive surgery and the extent of lymph node metastasis as factors in determining an appropriate surgical treatment for MCN. The present study retrospectively analyzed 21 consecutive patients who underwent distal pancreatectomy (DP) for MCN under general anesthesia at Chiba University Hospital (Chiba, Japan) between April 2011 and July 2019. All 21 patients were female. DP with a splenectomy was performed in all the patients. A total of 14 patients underwent laparoscopic DP (LDP). No lymph node metastasis was found in any of the patients. The minimally invasive surgery group had lower operative blood loss and a shorter hospital stay than the open surgery group. There was no significant difference in the number of dissected lymph nodes between the open surgery group and the minimally invasive surgery group. Preoperative findings of malignancy in MCN included solid components on enhanced CT and endoscopic ultrasonography, high carbohydrate antigen 19-9 values and large tumor size. In conclusion, DP with spleen preservation, which is minimally invasive, may be preferentially considered as a surgical technique for MCN without malignant findings because lymph node metastases are rare in MCN and were not observed in the present study.

Abstract
Ring1 and YY‑1 binding protein (RYBP) is a member of the polycomb repressive complex 1 and serves as a transcriptional suppressor via epigenetic modification. RYBP has a tumour‑suppressive role in solid tumours, but its function in colorectal cancer (CRC) remains unknown. The present study evaluated the expression of RYBP using immunohistochemistry in 140 cases of primary CRC and 11 patient‑matched cases of liver metastases. Using CRC cell lines with different TP53 gene status such as HCT116 (TP53wt/wt), HCT116 (TP53‑/‑), SW48 and DLD‑1 cells, proliferation, cell cycle progression and apoptosis, as well as the effect of RYBP on oxaliplatin sensitivity, were assessed. Clinical data showed that low RYBP expression was significantly associated with risk of distant metastasis and recurrence, and patients with high RYBP expression demonstrated significantly better cancer‑specific and disease‑free survival. In vitro experiments revealed that RYBP suppressed cell proliferation by inducing cell cycle arrest and apoptosis in TP53 wild‑type cells. In addition, endogenous RYBP overexpression enhanced sensitivity to oxaliplatin. Therefore, RYBP may contribute to improved prognosis in CRC by regulating the cell cycle, apoptosis and oxaliplatin sensitivity via the p53‑mediated pathway.

Abstract
BACKGROUND & AIMS Notch1 activation promotes ICC progression and is associated with chemoresistance; however, therapies directly targeting Notch1 showed severe adverse effects. Notch1 activation is mediated by ADAM10, a molecular scissor that separates the target protein from its substrates in the cell membrane. Tspan15 regulates ADAM10 function, but the role of Tspan15 in ICC progression is unclear. METHODS Tspan15, ADAM10, and Notch1 expression and activation in fresh surgical specimens from 80 ICC patients and ICC cells were evaluated by immunohistochemistry, RT-PCR, western blotting, and flow cytometry. RESULTS Tspan15 expression was increased in ICC compared with adjacent liver tissue, and high Tspan15 expression was an independent factor for poor prognosis. In ICC with high Tspan15 expression, vascular invasion, lymph node metastasis, and haematogenous recurrence were increased. Tspan15 was co-expressed with ADAM10 in ICC, and associated with the expression of stemness and EMT markers. In ICC cells, Tspan15 induced ADAM10 activation by mediating the translocation of activated m-ADAM10 from the cytoplasm to the surface of the cell membrane, which further activated Notch1 by separating the intracellular domain of Notch1 from its extracellular domain, leading to enhancement of CSC-like properties and EMT. This signalling was associated with enhanced chemoresistance against gemcitabine and cisplatin. Inhibition of Tspan15 or ADAM10 is a promising therapeutic strategy in ICC, as Tspan15 or ADAM10 knockdown or treatment with ADAM10 inhibitor reduced chemoresistance and invasiveness by suppressing Notch1-mediated CSC-like properties and EMT. CONCLUSIONS Tspan15-ADAM10-Notch1 signalling is associated with aggressive tumour progression and poor prognosis in ICC.

Abstract
PURPOSE Semaphorins, axon guidance cues in neuronal network formation, have been implicated in cancer progression. We previously identified semaphorin 3 C (SEMA3C) as a secreted protein overexpressed in pancreatic ductal adenocarcinoma (PDAC). We, therefore, hypothesized that SEMA3C supports PDAC progression. In this study, we aimed to investigate the clinical features of SEMA3C, especially its association with chemo-resistance and peritoneal dissemination. METHODS In resected PDAC tissues, we assessed the relationship between SEMA3C expression and clinicopathological features by immunohistochemistry. In vitro studies, we have shown invasion assay, pancreatosphere formation assay, colony formation assay, cytotoxicity assay, and activation of SEMA3C downstream targets (c-Met, Akt, mTOR). In vivo, we performed a preclinical trial to confirm the efficacy of SEMA3C shRNA knockdown and Gemcitabine and nab-Paclitaxel (GnP) in an orthotopic transplantation mouse model and in peritoneal dissemination mouse model. RESULTS In resected PDAC tissues, SEMA3C expression correlated with invasion and peritoneal dissemination after surgery. SEMA3C promoted cell invasion, self-renewal, and colony formation in vitro. We further demonstrated that SEMA3C knockdown increased Gem-induced cytotoxicity by suppressing the activation of the Akt/mTOR pathway via the c-Met receptor. Combination therapy with SEMA3C knockdown and GnP reduced tumor growth and peritoneal dissemination. CONCLUSIONS SEMA3C enhances peritoneal dissemination by regulating putative cancer stemness and Gem resistance and activates phosphorylation of the Akt/mTOR pathway via c-Met. Our findings provide a new avenue for therapeutic strategies in regulating peritoneal dissemination during PDAC progression.

Abstract
BACKGROUND Although both proximal ductal margin status and lymph node metastasis status influence the survival of patients with perihilar cholangiocarcinoma, the effect of proximal ductal margin status on survival according to lymph node metastasis status is unclear. The aim of this study was, thus, to evaluate the prognostic impact of proximal ductal margin status in perihilar cholangiocarcinoma according to the presence or absence of lymph node metastasis. METHODS Consecutive patients with perihilar cholangiocarcinoma who underwent major hepatectomy between June 2000 and August 2021 were retrospectively reviewed. Patients with Clavien-Dindo grade V complications were excluded from the analysis. Overall survival was assessed according to the combination of lymph node metastasis and proximal ductal margin status. RESULTS Of the 230 eligible patients, 128 (56%) were lymph node metastasis negative, and 102 (44%) were lymph node metastasis positive. Overall survival was significantly better in lymph node metastasis negative than lymph node metastasis positive patients (P < .0001). Of the 128 lymph node metastasis-negative patients, 104 (81%) were proximal ductal margin negative, and 24 (19%) were proximal ductal margin positive. In lymph node metastasis-negative patients, overall survival was worse in the proximal ductal margin positive than the proximal ductal margin negative group (P = .01). Of the 102 lymph node metastasis-positive patients, 72 (71%) were proximal ductal margin negative and 30 (29%) were proximal ductal margin positive. In these patients, overall survival was similar between the 2 groups (P = .10). CONCLUSION In patients with perihilar cholangiocarcinoma, the prognostic impact of proximal ductal margin positivity on survival might differ according to the presence or absence of lymph node metastasis.

Abstract
Case 1: A 73-year-old male, who had an intraductal papillary mucinous adenocarcinoma or resectable pancreatic cancer at the uncinate process of the pancreas five years after subtotal esophagectomy for esophageal cancer, underwent pylorus preserving pancreaticoduodenectomy(PPPD). Case 2: A 68-year-old male, who also had a resectable pancreatic cancer at the uncinate process of the pancreas 3 years after subtotal esophagectomy for esophageal cancer, underwent PPPD following neoadjuvant chemotherapy. In both cases, right gastroepiploic artery and vein were preserved to maintain the perfusion of the gastric tube during surgery. Indocyanine Green(ICG)fluorography was performed just before duodenal-jejunal anastomosis, which visually showed the well-perfused gastric tube. Both patients had no necrosis of the gastric tube, nor gastrointestinal obstruction after surgery. Intraoperative ICG fluorography was useful to evaluate the blood flow of the remaining gastric tube visually during PPPD for post-esophagectomy patients.

Abstract
BACKGROUND & AIMS TRIM27 is stabilized by binding to USP7 and mediates tumour progression in several cancers; however, the roles of TRIM27-USP7 complex on STAT3 activation in HCC are unknown. METHODS Regulations and functions of TRIM27 for activating STAT3 in HCC were assessed using 207 HCC samples or HCC cells. RESULTS TRIM27 expression was increased in some cases of HCC. High TRIM27 expression was an independent predictor for poor prognosis in HCC after surgery. It was correlated with the expression of EpCAM, vimentin, MMP-9, and activation of STAT3 in HCC. TRIM27 expression was correlated with USP7 expression, and HCC with high TRIM27 expression together with high USP7 expression showed enhanced STAT3 activation, resulting in poorer prognosis. p-JAK1 expression was correlated with STAT3 activation in HCC with high TRIM27 expression. In vitro, USP7 knockdown decreased TRIM27 expression, suggesting that USP7 was essential for TRIM27 stabilization. Knocking down of TRIM27 or USP7 suppressed STAT3 activation and overexpression of TRIM27 accelerated STAT3 activation; therefore, the formation of TRIM27-USP7 complex was needed for STAT3 activation, which led to aggressive tumour proliferation and invasion by enhancing EMT and CSC-like property. Binding of JAK1 to TRIM27-USP7 complex was confirmed in vitro. Deletion of TRIM27-USP7 complex by USP7 inhibitor significantly inhibited tumour cell invasion by suppressing STAT3 activation. CONCLUSIONS TRIM27 is stabilized by binding to USP7 and is related to aggressive tumour progression in HCC via STAT3 activation, resulting in poor prognosis after operation. Therefore, TRIM27-USP7 complex is a useful prognostic predictor and a promising therapeutic target for HCC.

Abstract
BACKGROUND Extrapancreatic nerve plexus (PL) invasion of pancreatic ductal adenocarcinoma (PDAC) is an important factor for determining resectability and surgical method. We sought to clarify the characteristics of PDAC with PL invasion and clinical impact of the resection margin status on prognosis for PDAC with PL invasion. METHODS A total of 242 patients with pancreatic head cancer who underwent pancreatectomy were evaluated. Clinicopathological data and patient survival were analyzed. RESULTS Pathological PL invasion was observed in 68 patients (28.1%). Patients with PL invasion had significantly shorter disease-free survival (DFS) and showed trends toward worse overall survival (OS) than those without PL invasion. While multivariate analysis revealed that PL invasion was not an independent prognostic factor, PL invasion was associated with extensive venous invasion and a high percentage of lymph node metastases, both of which were independent factors affecting DFS and OS. Among patients with PL invasion, there was no significant difference in DFS and OS between the R0 and R1 resection groups. CONCLUSIONS PL invasion is a common pathological feature of aggressive PDAC with high propensity for invasiveness and metastatic potential. The microscopic resection margin status may not affect the survival of pancreatic head cancer patients with PL invasion.

Abstract
Glycoproteins produced by tumor cells are involved in cancer progression, metastasis, and the immune response, and serve as possible therapeutic targets. Considering the dismal outcomes of pancreatic ductal adenocarcinoma (PDAC) due to its unique tumor microenvironment, which is characterized by low antitumor T-cell infiltration, we hypothesized that tumor-derived glycoproteins may serve as regulating the tumor microenvironment. We used glycoproteomics with tandem mass tag labeling to investigate the culture media of three human PDAC cell lines, and attempted to identify the key secreted proteins from PDAC cells. Among the identified glycoproteins, prosaposin (PSAP) was investigated for its functional contribution to PDAC progression. PSAP is highly expressed in various PDAC cell lines; however, knockdown of intrinsic PSAP expression did not affect the proliferation and migration capacities. Based on the immunohistochemistry of resected human PDAC tissues, high PSAP expression was associated with poor prognosis in patients with PDAC. Notably, tumors with high PSAP expression showed significantly lower CD8+ T-cell infiltration than those with low PSAP expression. Furthermore, PSAP stimulation decreased the proportion of CD8+ T cells in peripheral blood monocytes. Finally, in an orthotopic transplantation model, the number of CD8+ T cells in the PSAP shRNA groups was significantly increased, resulting in a decreased tumor volume compared with that in the control shRNA group. PSAP suppresses CD8+ T-cell infiltration, leading to the promotion of PDAC progression. However, further studies are warranted to determine whether this study contributes to the development of a novel immunomodulating therapy for PDAC.

Abstract
OBJECTIVES It has been reported that sarcopenia is associated with higher postoperative complication rates in various surgeries and with a poorer prognosis in various carcinomas. However, many of these reports did not strictly follow the definition of sarcopenia. Therefore, we prospectively evaluated the influence of sarcopenia, as defined by the European Working Group on Sarcopenia in Older People 2 (EWGSOP2), on complications after pancreaticoduodenectomy (PD) and on the prognosis of pancreatic head carcinoma. METHODS We prospectively investigated 180 patients who underwent PD at Chiba University Hospital from January 2016 to March 2020. The skeletal muscle mass, grip strength, and gait speed of the patients were measured preoperatively. Sarcopenia was defined in accordance with the EWGSOP2 definition. We evaluated the frequency and severity of postoperative complications in infectious, non-infectious, and overall complications. We analyzed the prognosis of 83 patients with pancreatic head carcinoma who underwent PD. RESULTS There were no differences in the severity and frequency of infectious, non-infectious, and overall complications between patients with and without sarcopenia. In patients with pancreatic head carcinoma, the recurrence-free and overall survival rates were significantly lower in patients with sarcopenia than in those without sarcopenia (P = 0.017 and P = 0.011, respectively). In multivariate analysis, sarcopenia was an independent risk factor for poor recurrence-free survival and overall survival (HR, 4.48; 95% CI, 1.68-11.98; P = 0.003 and HR, 3.25; 95% CI, 1.19-8.86; P = 0.021, respectively). CONCLUSIONS Sarcopenia, as defined by EWGSOP2, did not affect complications after PD. Sarcopenia is an important prognostic factor for surgically resected pancreatic head carcinoma.

Abstract
INTRODUCTION Although the prognosis of patients with resected perihilar cholangiocarcinoma (PHC) with histological lymph node metastasis (LNM) is poor, preoperative prediction of LNM is difficult. This study aimed to evaluate the diagnostic performance of diffusion-weighted magnetic resonance imaging (DWI) for LNM of PHC. METHOD Consecutive patients who underwent surgical resection of PHC between January 2012 and May 2020 were retrospectively reviewed. The lymph node (LN) area (mm2) and apparent diffusion coefficient (ADC) value ( × 10-3 mm2/s) of pericholedochal LNs were measured by DWI. The characteristics of the patients and the LNs were evaluated according to the histological presence or absence of regional LNM. Univariate and multivariate analyses were performed to identify the predictors of LNM of PHC. RESULTS Of the 93 eligible patients, 49 (53%) were LNM positive and 44 (47%) were LNM negative. Although the characteristics of the patients were similar between the two groups, the mean ADC value was significantly lower in the LNM positive group than in the LNM negative group. On multivariate analysis, mean ADC value ≤1.80 × 10-3 mm2/s was independently associated with LNM of PHC (risk ratio: 12.5, 95% confidence interval: 3.05-51.4; p = 0.0004). The sensitivity, specificity and accuracy of mean ADC values ≤ 1.80 × 10-3 mm2/s for predicting LNM of PHC were 94%, 55% and 75%, respectively. CONCLUSIONS DWI might be useful for the preoperative diagnosis of LNM of PHC.

BACKGROUND Although the most important goal in surgery for perihilar cholangiocarcinoma (PHC) is to achieve tumor-free proximal ductal margins, little is known about the implications of confluence patterns of the left intrahepatic bile ducts for the proximal ductal margin status in right hepatectomy (RH) for PHC. METHODS Of 203 patients who underwent surgical resection for PHC with curative intent, confluence patterns of the left intrahepatic bile duct were evaluated in 94 consecutive patients who underwent RH, and they were classified into the following two types: normal type: the bile duct of segment 4 (B4) drained into the common trunk of the bile ducts of segment 2 (B2) and segment 3 (B3) at the right side of the umbilical portion of the left portal vein to form the left hepatic duct; and hepatic confluence type: B2 entered the common trunk of B3 and B4 at the hepatic confluence or B4 entered the common trunk of B2 and B3 at the hepatic confluence. The proximal ductal margin status following RH was compared between the two types of confluence patterns. RESULTS Of 94 consecutive patients, 69 (73%) were the normal type, and 25 (27%) were the hepatic confluence type. There were no significant differences in patients' characteristics, surgical characteristics, surgical outcomes, and histopathological features between the two groups. However, in patients with Bismuth-Corlette type II and IIIa PHC, the achievement rates of negative proximal ductal margins at the first dividing line were significantly higher in the hepatic confluence type group than in the normal type group (16/16 [100%] vs 34/52 [65%], respectively; P = .007). CONCLUSIONS Confluence patterns of the left intrahepatic bile ducts might affect proximal ductal margin status in RH for PHC.

Abstract
PURPOSE The effect of hepatic steatosis on the development of colorectal liver metastases (CRLM) remains unknown. This study evaluated the usefulness of fat signal fraction assessed with magnetic resonance imaging (MRI) and the effect of hepatic steatosis on hepatic recurrences following initial hepatectomy for CRLM. METHODS Between January 2013 and December 2019, 64 patients underwent initial hepatectomy for CRLM. The medical records of these patients were reviewed to evaluate the recurrence and survival outcomes. RESULTS The fat signal fraction was positively correlated with the nonalcoholic fatty liver disease activity score and liver-spleen ratio. Recurrence following the initial hepatectomy was observed in 48/64 patients, and hepatic recurrence was observed in 30/64 patients. The fat signal fraction was significantly higher in patients with hepatic recurrence after initial hepatectomy. The hepatic recurrence rate was 69.2% in patients with fat signal fraction ≥ 0.0258, which was significantly higher than that in patients with fat signal fraction < 0.0258. Hepatic recurrence-free survival rate was significantly higher in patients with fat signal fraction < 0.0258 than in those with fat signal fraction ≥ 0.0258. Multivariate analyses revealed that fat signal fraction ≥ 0.0258 was an independent risk factor for hepatic recurrence. CONCLUSION The fat signal fraction assessed with MRI was significantly associated with hepatic recurrence following initial hepatectomy for CRLM.

Abstract
Yin Yang 1 (YY1) is a multifunctional transcription factor with critical roles in carcinogenesis and metastasis. However, its biological role and clinical impact in colorectal cancer (CRC) remain unclear. In the present study, the function and underlying molecular mechanisms of YY1 in CRC progression were investigated. The immunohistochemistry (IHC) of 143 CRC tissues revealed a significant correlation of low YY1 expression with aggressive clinicopathological features, increased metastasis and recurrence and poor patient survival. Multivariate analysis identified low YY1 expression as an independent poor prognostic factor. Subsequently, the IHC of 66 paired CRC primary tumor and liver metastasis tissues revealed that low YY1 expression in the primary CRC was significantly associated with multiple liver metastases, major hepatectomy, extrahepatic metastasis and poor prognosis. In vitro experiments revealed that YY1 knockdown promoted the migration and invasion of CRC cells. To examine the downstream genes of YY1, a cDNA microarray assay was conducted and the differentially expressed genes between the YY1‑knockdown and control cells were compared. Integrin alpha V (ITGAV) and integrin beta 1 (ITGB1) were identified as upregulated hub genes using gene enrichment analysis and protein‑protein interaction analyses. Western blotting and IHC confirmed YY1 expression to be negatively correlated with ITGAV and ITGB1 expression. In summary, it was revealed that YY1, as a tumor‑suppressor in CRC, contributes to the survival of patients with CRC. Low YY1 expression was associated with the poor prognosis of the patients with primary CRC and liver metastases. YY1 suppressed the expression of ITGAV and ITGB1, and this transcriptional regulation may lead to the suppression of CRC cell migration and invasion.

Abstract
The optimal regimens of neoadjuvant chemotherapy (NAC) and its biological and physiological modification of the tumor microenvironment (TME) in patients with borderline resectable pancreatic ductal adenocarcinoma (BR PDAC) remain unknown. A deeper understanding of the complex stromal biology of the TME will identify new avenues to establish treatment strategies for PDAC patients. Herein, we sought to clarify whether stromal remodeling by NAC affects recurrence patterns and prognosis in BR PDAC patients. We retrospectively analyzed data from 104 BR PDAC patients who underwent pancreatectomy with or without NAC (upfront surgery [UpS], n = 44; gemcitabine + nab-paclitaxel [GnP], n = 28; and gemcitabine + S-1 [GS], n = 32) to assess the correlations of treatment with early recurrence, the stromal ratio, and Ki-67 levels. Eighty-six patients experienced recurrence, and those with liver metastasis had significantly shorter recurrence-free survival than those with other recurrence patterns. The frequency of liver metastasis was significantly higher in patients with a low stromal ratio than in those with a high stromal ratio in the NAC group but not in the UpS group. Patients in the GnP group had significantly higher Ki-67 than those in the GS and UpS groups. A low stromal ratio was positively correlated with high Ki-67 in the NAC group but not in the UpS group. The low stromal ratio induced by NAC promoted early liver metastasis in patients with BR PDAC. Our findings provide new insights into the complexity of stromal biology, leading to consideration of the optimal NAC regimen.

Abstract
BACKGROUND The interplay between cancer cells and stromal components, including soluble mediators released from cancer cells, contributes to the progression of pancreatic ductal adenocarcinoma (PDAC). Here, we set out to identify key secreted proteins involved in PDAC progression. METHODS We performed secretome analyses of culture media of mouse pancreatic intraepithelial neoplasia (PanIN) and PDAC cells using Stable Isotope Labeling by Amino acid in Cell culture (SILAC) with click chemistry and liquid chromatography-mass spectrometry (LC-MS/MS). The results obtained were verified in primary PDAC tissue samples and cell line models. RESULTS Complement factor B (CFB) was identified as one of the robustly upregulated proteins, and found to exhibit elevated expression in PDAC cells compared to PanIN cells. Endogenous CFB knockdown by a specific siRNA dramatically decreased the proliferation of PDAC cells, PANC-1 and MIA PaCa-II. CFB knockdown induced increases in the number of senescence-associated-β-galactosidase (SA-β-gal) positive cells exhibiting p21 expression upregulation, which promotes cellular senescence with cyclinD1 accumulation. Furthermore, CFB knockdown facilitated downregulation of proliferating cell nuclear antigen and led to cell cycle arrest in the G1 phase in PDAC cells. Using immunohistochemistry, we found that high stromal CFB expression was associated with unfavorable clinical outcomes with hematogenous dissemination after surgery in human PDAC patients. Despite the presence of enriched CD8+ tumor infiltrating lymphocytes in the PDAC tumor microenvironments, patients with a high stromal CFB expression exhibited a significantly poorer prognosis compared to those with a low stromal CFB expression. Immunofluorescence staining revealed a correlation between stromal CFB expression in the tumor microenvironment and an enrichment of immunosuppressive regulatory T-cells (Tregs), myeloid-derived suppressor cells (MDSCs) and tumor-associated macrophages (TAMs). We also found that high stromal CFB expression showed a positive correlation with high CD8+/Foxp3+ Tregs populations in PDAC tissues. CONCLUSIONS Our data indicate that CFB, a key secreted protein, promotes proliferation by preventing cellular senescence and is associated with immunological tumor promotion in PDAC. These findings suggest that CFB may be a potential target for the treatment of PDAC.

Abstract
Background Recent studies indicate that complement plays pivotal roles in promoting or suppressing cancer progression. We have previously identified C4b-binding protein α-chain (C4BPA) as a serum biomarker for the early detection of pancreatic ductal adenocarcinoma (PDAC). However, its mechanism of action remains unclear. Here, we elucidated the functional roles of C4BPA in PDAC cells and the tumor microenvironment. Methods We assessed stromal C4BPA, the C4BPA binding partner CD40, and the number of CD8+ tumor-infiltrating lymphocytes in resected human PDAC tissues via immunohistochemical staining. The biological functions of C4BPA were investigated in peripheral blood mononuclear cells (PBMCs) and human PDAC cell lines. Mouse C4BPA (mC4BPA) peptide, which is composed of 30 amino acids from the C-terminus and binds to CD40, was designed for further in vitro and in vivo experiments. In a preclinical experiment, we assessed the efficacy of gemcitabine plus nab-paclitaxel (GnP), dual immune checkpoint blockades (ICBs), and mC4BPA peptide in a mouse orthotopic transplantation model. Results Immunohistochemical analysis revealed that high stromal C4BPA and CD40 was associated with favorable PDAC prognosis (P=0.0005). Stromal C4BPA strongly correlated with the number of CD8+ tumor-infiltrating lymphocytes (P=0.001). In in vitro experiments, flow cytometry revealed that recombinant human C4BPA (rhC4BPA) stimulation increased CD4+ and CD8+ T cell numbers in PBMCs. rhC4BPA also promoted the proliferation of CD40-expressing PDAC cells. By contrast, combined treatment with gemcitabine and rhC4BPA increased PDAC cell apoptosis rate. mC4BPA peptide increased the number of murine T lymphocytes in vitro and the number of CD8+ tumor-infiltrating lymphocytes surrounding PDAC tumors in vivo. In a preclinical study, GnP/ICBs/mC4BPA peptide treatment, but not GnP treatment, led to the accumulation of a greater number of CD8+ T cells in the periphery of PDAC tumors and to greater tumor regression than did control treatment. Conclusions These findings demonstrate that the combination of GnP therapy with C4BPA inhibits PDAC progression by promoting antitumor T cell accumulation in the tumor microenvironment.

Abstract
BACKGROUND Phosphorylated mammalian target of rapamycin (p-mTOR) plays a crucial role in the process of cancer progression. Common gene mutations of colorectal cancer lead to the activation of the PI3k/Akt/mTOR pathway. In this study, we determined whether p-mTOR expression in colorectal liver metastases is a predictive marker of prognosis following liver resection. METHODS Eighty-one patients with colorectal liver metastases who had undergone curative resection were evaluated using immunohistochemistry of p-mTOR. Data regarding clinicopathological features and patient survival were analyzed. RESULTS The p-mTOR expression in colorectal liver metastases was detected in 55 (67.9%) patients. Patients whose metastases had high p-mTOR expression showed a significantly lower overall survival rate after resection as compared to patients with low p-mTOR expression (p = 0.016), while there was no significant difference in the disease-free survival between the two groups. Repeat resection for recurrence was performed more frequently in patients with p-mTOR positive than others (p = 0.024). Multivariate analysis showed that p-mTOR expression was an independent prognostic factor of overall survival after liver resection (p = 0.019). CONCLUSIONS mTOR was frequently activated in colorectal liver metastases, and the p-mTOR expression was a biological marker for predicting the overall survival of patients with colorectal liver metastases following liver resection.

Abstract
BACKGROUND Major hepatectomy with bile duct resection (BDR) is associated with severe postoperative complications; therefore, evaluation of preoperative liver function is important. However, little is known about mechanisms of increased severe complications in patients with poor liver function. The aim of this study was to evaluate whether indocyanine green retention rate after 15 minutes of injection (ICG-R15) is useful for predicting the risk of severe postoperative complications in this operation, and to reveal the mechanisms of increasing severe complications by focusing on immune function and liver regeneration after hepatectomy. METHODS Patients receiving major hepatectomy with BDR between 2000 and 2017 were retrospectively reviewed. Severe postoperative complications were defined as Clavien-Dindo grade ≥IV. RESULTS In 284 patients undergoing major hepatectomy with BDR, ICG-R15 was correlated with severe postoperative complications, with cut-off value of 11.8%. In brief, the incidences of hyperbilirubinemia, coagulopathy, liver failure, respiratory failure, severe complications, and mortality were higher in the high ICG-R15 group. Moreover, high ICG-R15 (≥11.8%) was an independent factor for predicting severe complications after major hepatectomy with BDR. Immune dysfunction in the early phase after operation, prolonged postoperative immunosuppression, and delayed liver regeneration were reasons for increasing severe postoperative complications in patients with high ICG-R15. CONCLUSIONS High ICG-R15 is an independent risk factor for severe complications after major hepatectomy with BDR, and its cut-off value is 11.8%. Compromised condition and delayed liver regeneration induced by immune dysfunction are reasons of increased severe postoperative complications in patients with high ICG-R15.

Abstract
Background The relationship between KRAS mutational status and timing of colorectal liver metastasis (CRLM) remains unclear. This study evaluated the relationship between KRAS mutational status and long-term survival in patients with synchronous CRLM. Methods Of the 255 patients who underwent initial hepatic resection for CRLM between January 2001 and December 2018, the KRAS mutational status was examined in 101 patients. Medical records of these patients were reviewed to evaluate recurrence and survival outcomes. Results KRAS mutant status was identified in 38 patients (37.6%). The overall survival (OS) was significantly better in patients with wild-type KRAS than in those with mutant KRAS status. In patients with synchronous metastases, the OS of patients with wild-type KRAS was significantly better than those with mutant KRAS. Multivariate analyses indicated shorter OS to be independently associated with positive primary lymph node, and large tumor size and R1 resection in patients with metachronous metastasis, whereas to be independently associated with mutant KRAS status in patients with synchronous metastasis. Furthermore, in the subgroup of patients with synchronous metastases, the repeat resection rate for hepatic recurrence was significantly high in those with wild type KRAS than in those with mutant KRAS. Conclusion KRAS mutation is an independent prognostic factor in patients with synchronous CRLM, but not in patients with metachronous CRLM.

Abstract
BACKGROUND & AIMS LGR5 enhances Wnt-β-catenin signalling; however, involvement of LGR5 or Wnt-β-catenin signalling in ICC progression has not been reported. METHODS Functions and regulations of LGR5-mediated β-catenin activation in ICC progression were evaluated using surgical specimens collected from 61 ICC patients or 2 ICC cell lines. RESULTS LGR5 expression was increased in some cases of ICC. It was positively correlated with β-catenin activation, OLFM4 expression and STAT3 activation, and negatively correlated with GRIM19 expression in ICC, thereby enhancing cancer stem cell (CSC)-like property and EMT. High LGR5 expression was an independent factor for poor prognosis in ICC after operation. In vitro, Wnt inhibition by IWP-2 suppressed β-catenin activation, OLFM4 expression and STAT3 activation. IWP-2 treatment decreased expression of EpCAM, CD133, vimentin and increased E-cadherin expression. The rate of mesenchymal cells was decreased and cell invasiveness was suppressed after IWP-2 treatment, suggesting that Wnt-β-catenin signalling enhanced CSC-like property and EMT by activating STAT3. In addition, LGR5 knockdown inhibited β-catenin activation, resulting in suppression of β-catenin-induced STAT3 activation through inhibition of OLFM4-GRIM19 cascade. As these results, LGR5 knockdown suppressed CSC-like property and EMT. Therefore, LGR5 was a key regulator for β-catenin activation, and β-catenin was unable to be activated without LGR5. CONCLUSIONS LGR5 is essential for β-catenin activation induced by Wnt signalling. Activated β-catenin further activates STAT3 and enhances CSC-like property and EMT, leading to aggressive tumour progression and poor prognosis in patients with ICC. Therefore, LGR5 is an excellent prognostic predictor and a promising therapeutic target for ICC.

Abstract
Surgical site infections (SSIs) are significant and frequent perioperative complications, occurring due to the contamination of the surgical site. The late detection of SSIs, especially organ/space SSIs which are the more difficult to treat, often leads to severe complications. An effective method that can identify bacteria with a high accuracy, leading to the early detection of organ/space SSIs, is needed. Ninety-eight drainage fluid samples obtained from 22 patients with hepatobiliary pancreatic disease were analyzed to identify microorganisms using matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) with a new membrane filtration protocol and rapid BACpro® pretreatment compared to sole rapid BACpro® pretreatment. The levels of detail of rapid BACpro® pretreatment with or without filtration were also evaluated for the accuracy of bacterial identification. We found that reliable scores for E. coli and E. faecalis were obtained by inoculation with 1.0 × 104 CFU/ml after preparation of the membrane filter with rapid BACpro®, indicating approximately 10-folds more sensitive compared to sole rapid BACpro® pretreatment in drainage fluid specimens. Among 60 bacterial positive colonies in drainage fluid specimens, the MALDI-TOF MS and the membrane filtration with rapid BACpro® identified 53 isolates (88.3%) with a significantly higher accuracy, compared to 25 isolates in the rapid BACpro® pretreatment group (41.7%) (p < 0.001). Among the 78 strains, 14 enteric Gram-negative bacteria (93.0%) and 55 Gram-positive cocci (87.3%) were correctly identified by the membrane filtration with rapid BACpro® with a high reliability. This novel protocol could identify bacterial species within 30 min, at $2-$3 per sample, thus leading to cost and time savings. MALDI-TOF MS with membrane filter and rapid BACpro® is a quick and reliable method for bacterial identification in drainage fluids. The shortened analysis time will enable earlier selection of suitable antibiotics for treatment of organ/space SSIs to improve patients' outcomes.

Abstract
Background Pancreatic ductal adenocarcinoma (PDAC) rarely metastasizes to the brain; therefore, the features of brain metastasis of PDAC are still unknown. We encountered simultaneous metastases to the brain and lung in a PDAC patient after curative surgery. Case presentation A 68-year-old man with PDAC in the tail of the pancreas underwent distal pancreato-splenectomy. He received gemcitabine as adjuvant chemotherapy for 6 months. Two months later, brain and lung metastases occurred simultaneously. Considering the systemic condition, the patient received gamma knife treatment and an Ommaya reservoir was inserted for drainage. The patient’s condition gradually worsened and he received the best supportive care. To the best of our knowledge, only 28 cases in which brain metastases of PDAC were identified at the time of ante-mortem have been reported to date, including the present case. Notably, the percentage of simultaneous brain and lung metastases was higher (32%) in a series of reviewed cohorts. Thus, lung metastasis might be one of the risk factors for the development of brain metastasis in patients with PDAC. As a systemic disease, it can be inferred that neoplastic cells will develop brain metastasis via hematogenous dissemination beyond the blood–brain barrier, even if local recurrence is controlled. In our case, immunohistochemical staining showed that the neoplastic cells were positive for carbonic anhydrase 9 (CAIX), mucin core protein 1 (MUC1), and MUC5AC in the resected primary PDAC. Conclusion We describe a case of simultaneous brain and lung metastases of PDAC after curative pancreatectomy, review previous literature, and discuss the clinical features of brain metastasis of PDAC.

Abstract
C4b-binding protein α-chain (C4BPA) was previously identified as a novel serum biomarker for pancreatic ductal adenocarcinoma (PDAC). To apply this biomarker for clinical diagnosis, a lectin ELISA was established to measure serum fucosylated (Fuc)-C4BPA levels in 45 patients with PDAC, 20 patients with chronic pancreatitis (CP) and 50 healthy volunteers (HVs) in one training and three validation sets. The lecithin ELISA developed in the current study exhibited satisfactory within-run (2.6–6.7%) and between-day (1.8–3.6%) coefficient of variations. Serum Fuc-C4BPA levels in patients with PDAC (0.54±0.27 AU/ml) was significantly higher than that in HVs (0.21±0.06 AU/ml; P<0.0001) and patients with CP (0.25±0.03 AU/ml; P<0.0001). Additionally, serum Fuc-C4BPA levels in preoperative patients were significantly decreased compared with postoperative patient sera (P<0.0003). The receiver operating characteristic (ROC) curve analyses revealed that the area under the curve (AUC) of Fuc-C4BPA (0.985) was higher than that of carbohydrate antigen (CA)19-9 (0.843), carcinoembryonic antigen (0.548) and total C4BPA (0.875) (P<0.001). To analyze the clinical significance of Fuc-C4BPA, the ability of Fuc-C4BPA to predict lymph node metastasis was compared with that of CA19-9. The AUC of serum Fuc-C4BPA levels (0.703) was significantly higher than that of serum CA19-9 levels (0.500) in patients with PDAC (P<0.001). The current study established a novel lectin ELISA for measuring serum Fuc-C4BPA levels. Thus, Fuc-C4BPA has potential clinical applications owing to its high diagnostic value in PDAC.

Abstract
BACKGROUND It remains unknown whether epithelial-mesenchymal transition (EMT)-mediated vascular invasion and cancer stemness are associated with sphingosine-1-phosphate receptor-1 (S1PR1) expression in human hepatocellular carcinoma (HCC). The aim of this study was to investigate the correlation between S1PR1 expression and prognosis of patients with primary HCC and to define the potential of S1PR as a therapeutic target. MATERIALS AND METHODS We investigated 108 patients who underwent primary surgical resection for HCC treatment. Expression of S1PR1 and EMT markers was analyzed to predict prognosis of patients with HCC. Furthermore, three-dimensional organotypic culture, anoikis assay, and cell invasion were performed to validate the association of S1PR1 with EMT and cancer stemness. RESULTS Among patients with HCC, the high S1PR1 expression group had significantly shorter overall survival than the low expression group. Moreover, high S1PR1 expression was significantly associated with shorter recurrence-free survival, increased risk of portal and hepatic vein invasion, and intrahepatic metastasis. Multivariate analyses revealed that S1PR1 overexpression was an independent prognostic factor in patients with HCC. S1PR1 overexpression positively correlated with vimentin and MMP-9 expression and negatively correlated with E-cadherin. In addition, S1PR1 overexpression induced EMT and enhanced tumor invasion and cancer stemness. CONCLUSIONS S1PR1 overexpression, via EMT-induced vascular invasion and increased cancer stem cell properties, establishes a metastatic niche, enhances the capacity of hematogenous metastasis, and associates with poor outcomes in patients with HCC. Hence, S1PR1 may serve as a therapeutic target for patients with HCC with vascular invasion.

Abstract
A 48-year-old female visited former doctor with abdominal pain and bloating. She was suspected of having pancreatic tumor and referred to our hospital. Abdominal dynamic CT showed multilocular cystic tumor in the pancreatic tail, and chest CT showed multiple lung nodules. From these findings, the patient was diagnosed mucinous cystic carcinoma(MCC)with lung metastases. We performed distal pancreatectomy for the first and lung resection after pancreatectomy. After all, the pathological diagnosis was MCC and metastatic lung cancer from the MCC. The adjuvant chemotherapy was not performed. Eleven months after pancreatectomy and 6 months after lung resection, the patient is still alive without recurrence.

Abstract
A 60-year-old man underwent distal pancreatectomy with splenectomy and combined resection partially of the stomach, jejunum, and left renal vein. We administered S-1 adjuvant chemotherapy for 1 year. After its completion, the patient showed no evidence of recurrence. However, his carbohydrate antigen(CA)19-9 level was elevated for 1 year and 8 months postoperatively. We administered gemcitabine chemotherapy. He was admitted for bowel obstruction 3 years and 10 months postoperatively. Conservative treatment with an ileus tube did not improve the bowel obstruction. Therefore, we performed the surgery. Intraoperative findings revealed peritoneal nodules invading the small intestine. We performed a small bowel bypass. Pathological examination revealed the peritoneal nodule of pancreatic cancer. Although we administered FOLFIRINOX chemotherapy postoperatively, his CA19-9 level remained elevated for 4 years and 8 months after the first surgery. Therefore, chemotherapy was changed to gemcitabine and nab-paclitaxel. Six years and 11 months after the first surgery and 5 years and 3 months after the diagnosis of peritoneal dissemination, he survives with recurrence. Herein, there were 2 contributors to long-term survival; the patient not only showed positive responses to each chemotherapy regimen but could also continue chemotherapy without developing significant adverse effects.

Abstract
BACKGROUND AND AIM Postoperative hemorrhage is a rare but potentially lethal complication of hepatobiliary and pancreatic surgeries. This study aimed to retrospectively evaluate the clinical outcome of patients with delayed postoperative hemorrhage and compare the results according to the surgical procedure. METHODS Overall, 4220 patients underwent surgery for hepatobiliary and pancreatic diseases. Delayed postoperative hemorrhage (observed more than 24 h postoperatively) occurred in 62 patients. Of these, 61 underwent interventional radiology to achieve hemostasis. Patients' clinical data were analyzed retrospectively. The chi-squared or Fisher's exact test was used in data analysis. RESULTS A total of 62 patients (1.5%) developed delayed postoperative hemorrhage; 61 (1.4%) of them underwent interventional radiology to achieve hemostasis. Median duration from surgery to interventional radiology was 19 days (range: 5-252 days). Sentinel bleeding was detected in 31 patients; Clinical success was achieved in 54 patients (88.5%) by interventional radiology. Overall mortality rate was 26.2%. Causes of 16 in-hospital deaths were uncontrollable hemorrhage (n = 4) and worsening of general condition after hemostasis (n = 12). Mortality rates were 50.0% (11/22) and 12.8% (5/39) after hepatobiliary surgery and pancreatic resection, respectively. Mortality rate was significantly higher after hepatobiliary surgery than after pancreatic surgery (P = 0.002). CONCLUSIONS Interventional radiology can be successfully performed to achieve hemostasis for delayed hemorrhage after hepatobiliary and pancreatic surgeries. Because successful interventional radiology does not necessarily lead to survival, particularly after hepatobiliary surgery, meticulous attention to prevent surgical complications and intensive treatments before and after interventional radiology are required to improve outcomes.

Abstract
BACKGROUND This study aimed to assess the prognostic values of preoperative maximum standardized uptake value (SUVmax) of primary pancreatic tumors and Glut-1 expression in patients with resectable pancreatic ductal adenocarcinoma (R-PDAC), and to investigate whether Glut-1 expression is more effective than SUVmax in predicting survival in patients with R-PDAC. METHODS We investigated 101 R-PDAC patients who underwent pancreatectomy for pancreatic cancer treatment. SUVmax analyzed through 18F-fluoro-2-deoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT), and Glut-1 expression, were assessed for predicting the prognosis of patients with R-PDAC. RESULTS In patients with R-PDAC, the high SUVmax group (≥4.25) had significantly shorter overall survival (OS) and disease-free survival (DFS) than the low SUVmax group (<4.25). Surprisingly, Glut-1 expression was not significantly correlated with SUVmax. Moreover, the high Glut-1 expression group, which was related to higher levels of CA 19-9, had significantly shorter OS and DFS than the low Glut-1 expression group. Furthermore, among the high SUVmax group, OS and DFS were significantly shorter in the high Glut-1 expression group. Multivariate analyses revealed that Glut-1 overexpression was an independent prognostic factor in patients with R-PDAC. Glut-1 knockdown also induced cell cycle arrest in PDAC cells in vitro. CONCLUSIONS The study determined that Glut-1 overexpression is a more powerful prognostic factor than SUVmax for predicting OS and higher risk of recurrence in R-PDAC patients. Glut-1 overexpression is also more likely to be associated with malignant activity in PDAC patients.

Abstract
Background Conversion chemotherapy may downsize unresectable colorectal liver metastases (CRLMs), but may cause liver injury and splenic enlargement. The effect of preoperative chemotherapy on liver regeneration after liver resection remains undetermined. The aim of this study was to examine whether splenic enlargement induced by preoperative chemotherapy is an indicator to identify high-risk patients for impaired liver regeneration and liver dysfunction after resection. Methods We retrospectively reviewed 118 Japanese patients with CRLMs. Fifty-one patients had conversion chemotherapy. The other 67 patients underwent up-front liver resection. We clarified effects of conversion chemotherapy on splenic volume, liver function, and postoperative liver regeneration. Perioperative outcome was also analyzed. Results A ratio of the splenic volume before and after chemotherapy (SP index) in the oxaliplatin-based chemotherapy group was significantly greater than other chemotherapy groups after 9 or more chemotherapy cycles. Patients whose SP index was 1.2 or more had significantly higher indocyanine green retention rate at 15 min (ICG-R15) than patients without chemotherapy. Analyses of covariance showed liver regeneration rate after resection was decreased in patients whose SP index was 1.2 or more. The incidence of postoperative liver dysfunction in patients whose SP index was 1.2 or more was significantly greater than patients without chemotherapy. Multivariate analysis showed SP index was a significant predictive factor of impaired liver regeneration. Conclusions Splenic enlargement induced by preoperative chemotherapy was a useful indicator for impaired liver regeneration after resection and a decision-making tool of treatment strategy for unresectable CRLMs.

Abstract
Krüppel‐like factor 5 (KLF5) plays an oncogenic role and has diverse functions in cancer cells. However, correlation between KLF5 and clinical outcome has not been determined in patients with colorectal cancer and colorectal liver metastasis. Herein, we analyzed 65 patients with colorectal cancer who developed colorectal liver metastasis. Clinical effects were assessed through immunohistochemical analysis of primary colorectal cancer lesions and metastatic liver lesions. High expression of KLF5 in these tissues correlated with the presence of vascular invasion, elevated serum carbohydrate antigen 19‐9 levels, large diameters of metastatic liver tumors, and poor prognosis following surgery. Multivariate analyses revealed that high expression of KLF5 was an independent prognostic factor. Increased expression of KLF5 in both colorectal cancer primaries and colorectal liver metastasis was significantly associated with shorter overall survival time and time to surgical failure. Krüppel‐like factor 5 expression positively correlated with Ki‐67 and c‐Myc expression in colorectal cancer tissues. In vitro experiments with colon cancer cell lines showed that siRNA knockdown of KLF5 inhibited cell proliferation. Western blot analyses revealed that knockdown of KLF5 expression reduced cyclin D1 and c‐Myc expression. It also impaired the stem cell‐like properties of cancer cells in tumorsphere formation assays. Furthermore, anoikis assay indicated that KLF5 contributed to anoikis resistance. High KLF5 expression is associated with poor prognosis in patients with colorectal cancer and liver metastasis by promoting cell proliferation and cancer stem cell‐like properties.

Abstract
BACKGROUND & AIMS Sarcopenia is considered a risk factor of postoperative complications among patients undergoing abdominal surgery. However, few studies have demonstrated an effective strategy for reducing complications in sarcopenic patients. This study aimed to examine retrospectively the effect of preoperative immunonutrition on postoperative complications, especially infectious complications, in low skeletal muscle mass patients undergoing pancreaticoduodenectomy (PD). METHODS This was a retrospective, consecutive cohort study conducted in our institution. Skeletal muscle mass was assessed using preoperative computed tomography images in 298 consecutive patients who underwent PD between May 2009 and May 2016. Cross-sectional areas at the third lumbar vertebrae normalized for stature (cm2/m2) were defined as the skeletal muscle mass index (SMI). Low SMI was defined as the lowest sex-specific quartile of SMI. Risk factors for postoperative infectious complications and the effect of preoperative immunonutrition on low SMI patients who underwent PD were evaluated. RESULTS Results of multivariate analysis showed that the presence of low SMI and absence of preoperative immunonutrition were independent risk factors for postoperative infectious complications after PD (odds ratio [OR], 3.17 and 3.10, respectively; P < 0.001). In high SMI patients, the rate of postoperative infectious complications was significantly lower in those who received immunonutrition than in those who did not receive immunonutrition (31.9 vs. 46.1%, respectively; OR, 1.82; P = 0.045). Further, similar findings were exhibited in low SMI patients (26.3 vs. 83.6%, respectively; OR, 14.31; P < 0.001), even though OR was markedly higher in low vs. high SMI patients. CONCLUSION There is a stronger association with reduced infectious complications in patients who have low SMI and receive immunonutrition (UMIN-CTR Identifier: UMIN000035775.).

Abstract
A 32-year-old woman presented with epigastric pain and an abdominal mass. Abdominal CT showed a 130mm pancreatic tail mass with an enhanced rim, central necrosis, and small calcification. A 6mm lung tumor was also found via chest CT. Her medical history included surgical resection of cerebral solitary fibrous tumor when she was 24 years old. When she was 31 years old, it had recurred but was cured by gamma knife radiosurgery. We performed distal pancreatectomy and splenectomy with lymph node dissection. According to pathological and immunohistochemical findings, it was diagnosed as an anaplastic carcinoma with osteoclast-like giant cells. She underwent surgical resection of the lung tumor 2 months after pancreatic resection and was diagnosed with metastasis from the solitary fibrous tumor. Fourteen months since undergoing pancreatectomy, the patient experienced no recurrence from both diseases. We report a rare resected case of anaplastic carcinoma of pancreas concomitant with recurrent solitary fibrous tumor.

Abstract
WHAT IS KNOWN AND OBJECTIVE Vitamin K deficiency is known to cause impaired coagulation. We report a case of marked prolongation of the prothrombin time-international normalized ratio (PT-INR) associated with warfarin and vitamin K deficiency caused by endoscopic nasobiliary drainage (ENBD). CASE PRESENTATION Oral administration of warfarin was initiated in a 67-year-old man after left hemihepatectomy. He developed a biliary fistula after surgery that was treated by ENBD, which resulted in significant prolongation of the PT-INR. WHAT IS NEW AND CONCLUSION The effect of warfarin was enhanced in this patient due to reduced absorption of vitamin K as a result of external biliary drainage.

Abstract
Background Invasive pancreatic neoplasms have a high propensity for recurrence even after curative resection. Recently, patients who underwent pancreatectomy have an opportunity of undergoing secondary pancreatic resection, so-called “repeat pancreatectomy” to achieve curative operation and prolong their survival. We evaluated the long-term clinical outcomes and identified the prognostic factors, including systemic inflammation markers and the lymphocyte-to-monocyte ratio (LMR) of patients who underwent repeat pancreatectomy for invasive pancreatic tumors. Methods Twenty-eight consecutive patients with invasive pancreatic neoplasms (22 pancreatic ductal adenocarcinomas, 2 pancreatic acinar cell carcinomas, and 4 invasive intra-papillary mucinous carcinomas) with isolated local recurrence only in the remnant pancreas were analyzed retrospectively. To identify factors for the selection of optimal patients who should undergo repeat pancreatectomy, perioperative clinical parameters were analyzed by Cox proportional regression models. Results Of 28 patients, 12 patients experienced recurrence within 3 years after repeat pancreatectomy. Kaplan–Meier analysis showed that the median cancer-specific overall survival time of patients with invasive pancreatic neoplasms was 61 months, showing favorable outcomes. High preoperative LMR (LMR ≥ 3.3) (p = 0.022), no portal vein resection (p = 0.021), no arterial resection (p = 0.037), and pathological lymph node negative (p = 0.0057) were identified as favorable prognostic parameters on univariate analysis, and LMR ≥ 3.3 (p = 0.0005), and pathological lymph node negative (p = 0.018) on multivariate analysis. Conclusions Preoperative LMR is potentially a good indicator for selecting suitable patients to undergo repeat pancreatectomy in patients with isolated local recurrence of invasive pancreatic neoplasms.

Abstract
Background Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has high accuracy and a low complication rate; therefore, it has been widely used as a useful tool for diagnosis of and to determine treatment strategies for pancreatic tumors. Recently, reports of the recurrence of needle tract seeding after EUS-FNA are emerging. Case presentation An 83-year-old woman was referred to our hospital to undergo further examination of her pancreatic tumor. Multidetector computed tomography (MDCT) revealed a 25-mm-diameter mass in the pancreatic body. She underwent EUS-FNA (transgastric, 22-G needle, 2 passes) and was subsequently diagnosed with adenocarcinoma. Distal pancreatosplenectomy followed by adjuvant chemotherapy with S-1 for 6 months was performed. The level of carbohydrate antigen 19–9 gradually increased 22 months after surgery, and MDCT, which was performed 3 months later, revealed a 23-mm low-density mass in the stomach and paragastric lymph node swelling. Gastroendoscopy revealed a submucosal tumor, and endoscopic ultrasound revealed a hypoechoic mass in the submucosa of the gastric wall. Partial gastrectomy with lymph node resection was performed. The pathological findings showed adenocarcinoma extending from the subserosa to the submucosa and lymph node metastasis, consistent with a tumor recurrence from the resected pancreatic tumor. She received adjuvant chemotherapy with S-1; recurrence was not observed for 5 months, at the time of this writing. Conclusion It is important to pay careful attention to the development of needle tract seeding in patients with pancreatic cancer diagnosed by EUS-FNA. This is the first case of needle tract seeding with lymph node metastasis, highlighting the need for caution and providing novel insight in the postoperative follow-up of patients with pancreatic body/tail cancer.

Abstract
Abstract
Introduction: The outcome of patients with borderline resectable pancreatic ductal adenocarcinoma (BR PDAC) remains dismal even if the patients received neoadjuvant chemotherapy followed by radical resection. Pancreatic resection is highly invasive and sometimes fatal; thus, useful preoperative indicators for favorable prognosis of patients with PDAC are needed. Lymphocyte-to-monocyte ratio (LMR) is a systemic inflammatory response marker associated with cancer outcome. In the present study, we evaluated the clinical significance of LMR for BR head-PDAC patients.
Materials and Methods: Consecutive 67 borderline resectable (BR) head-PDAC patients who underwent pancreaticoduodenectomy from Jan. 2008 to Dec. 2017 at Chiba University Hospital were analyzed retrospectively. The levels of LMR were calculated by simply dividing the absolute lymphocyte count by the monocyte count from routine preoperative blood sample, and the cut-off value of LMR was determined by receiver operating curve analysis. All the participants were divided into two groups (High/Low) based on the level of LMR. Among the clinicopathologic factors, we analyzed the clinical significance of preoperative LMR using the Kaplan-Meier analysis and Cox proportional regression model.
Results: The characteristics of participants were as follows: median age: 67 (interquartile range (IQR) 61-72) years old, sex M/F: 49/18, resectability based on NCCN 2018.2 (BR-PV/BR-A): 38/29, neoadjuvant chemotherapy (done/none): 36/31, adjuvant chemotherapy (done/none): 59/8, R0/1 resection: 51/16, respectively. The median level of preoperative LMR was 4.17 (IQR 2.51-6.09). The cut-off value of LMR was calculated to be 5.63 by applying Youden Index. All PDAC patients were classified into high LMR group (n=20) and low LMR group (n=47). The Kaplan-Meier analysis showed that the outcome of patients in high LMR group was significantly better compared to that in low LMR group (P=0.029 log-rank test). The median overall survival time after surgery was 17.6 months in low LMR group versus 38.1 months in high LMR group. Furthermore, multivariate analysis revealed that high LMR (P=0.012) and low preoperative CA19-9 level (P=0.012) were identified as independent prognostic factors of favorable outcomes in patients with BR head-PDAC.
Conclusions: The present study demonstrated both LMR and preoperative CA19-9 were independent prognostic factors in patients with BR head-PDAC. Because these markers can be obtained preoperatively, they will contribute to determination of the strategy for treatment of BR PDAC patients.
