Abstract
Insufficient cancer treatment can induce senescent cancer cell formation and treatment resistance. The characteristics of induced senescent cancer (iSnCa) cells remain unclear. Pancreatic ductal adenocarcinoma (PDAC) has a low and nondurable response rate to current treatments. Our study aimed to analyze the properties of iSnCa cells and the relationship between cellular senescence and prognosis in PDAC. We evaluated the characteristics of gemcitabine-induced senescent cancer cells and the effect of senescence-associated secretory phenotype (SASP) factors released by iSnCa cells on surrounding PDAC cells. The relationship between cellular senescence and the prognosis was investigated in 50 patients with PDAC treated with gemcitabine-based neoadjuvant chemotherapy. Exposure to 5 ng/mL gemcitabine-induced senescence, decreased proliferation and increased senescence-associated β-galactosidase-cell staining without cell death in PDAC cells; the expression of glutaminase1 (GLS1) and SASP factors also increased and caused epithelial-mesenchymal transition in surrounding PDAC cells. iSnCa cells were selectively removed by the GLS1 inhibitor bis-2-(5-phenylacetamido-1,2,4-thiadiazol-2-yl)ethyl sulfide (BPTES) through apoptosis induction. Cellular senescence was induced in PDAC cells via insufficient gemcitabine in subcutaneous tumor model mice. GLS1 expression was an independent prognostic factor in patients with PDAC who received gemcitabine-based neoadjuvant chemotherapy. This is the first study to identify the relationship between senescence and GLS1 in PDAC. Low-dose gemcitabine-induced senescence and increased GLS1 expression were observed in PDAC cells. Cellular senescence may contribute to treatment resistance of PDAC, hence targeting GLS1 in iSnCa cells may improve the therapeutic effect.

Abstract
Since the insurance coverage of colorectal stents for bowel obstruction due to colorectal cancer in 2012, the use of colorectal stenting for palliation has rapidly spread. We report a case of ascending colon cancer in which a colorectal stent was placed for palliation, but the stent was reimplanted due to obstruction, followed by radical resection. The patient was a 92- year-old woman who was brought to the emergency room at the age of 90 years with repeated vomiting and abdominal pain, and was diagnosed as colorectal cancer ileus caused by ascending colon cancer, and a colorectal stent was inserted. She received palliative care and had been asymptomatic for 1 year and 3 months, but due to in-stent stenosis, she had bowel obstruction and sent to emergency room, and another stent was installed. The patient had a good course, but 4 months after the second stenting, she was concerned about restenosis and referred to the department of surgery, then performed a radical resection. The indication for colorectal stents for palliative purposes should be considered on a case-by- case basis, including ADL, stage of the disease, and prognosis.

Abstract
OBJECTIVE Percutaneous transhepatic gallbladder aspiration (PTGBA) and/or drainage (PTGBD) are useful approaches in the management of acute cholecystitis in patients who cannot tolerate surgery because of poor general condition or severe inflammation. However, reports regarding its effect on the surgical outcomes of subsequent laparoscopic cholecystectomy (LC) are sparse. The aim of this retrospective study was to investigate the influence of PTGBA on surgical outcomes of subsequent LC by comparing the only-PTGBA group, including patients who did not need the additional-PTGBD, versus the additional-PTGBD group, including those who needed the additional-PTGBD after PTGBA. PATIENTS AND METHODS We conducted a post hoc analysis of our multi-institutional data. This study included 63 patients who underwent LC after PTGBA, and we compared the surgical outcomes between the only-PTGBA group (n = 56) and the additional-PTGBD group (n = 7). RESULTS No postoperative complications occurred among the 63 patients, and the postoperative hospital stay was 11 ± 12 days. Fourteen patients (22.2%) had a recurrence of cholecystitis, of whom 7 patients (11.1%) needed the additional-PTGBD after PTGBA. Significantly longer operative time (245 ± 74 vs 159 ± 65 min, P = 0.0017) and postoperative hospital stay (22 ± 27 vs 10 ± 9 d, P = 0.0118) and greater intraoperative blood loss (279 ± 385 vs 70 ± 208 mL, P = 0.0283) were observed among patients in the additional-PTGBD group compared with the only-PTGBA group, whereas the rates of postoperative complications (Clavien-Dindo grade ≥3: 0% each) and conversion to open surgery (28.6% vs 8.9%, P = 0.1705) were comparable. CONCLUSION PTGBA for acute cholecystitis could result in good surgical outcomes of subsequent LC, especially regarding postoperative complications. However, we should keep in mind that the additional-PTGBD after PTGBA failure, which sometimes happened, would be associated with increased operative difficulty and longer recovery.

Abstract
An 84-year-old man with gastric cancer, cT2N0M0, cStage Ⅰ underwent laparoscopic distal gastrectomy, D1+dissection, and Roux-en-Y reconstruction. We started enteral nutrition on the second postoperative day, but milky drainage appeared from the drain on the fifth postoperative day. The triglyceride in the ascites was markedly elevated, and it was diagnosed as a lymphorrhea. Neither conservative treatment nor lymphangiography were successful. We decided to perform surgical intervention because the lymphorrhea did not improve for about 1 month after gastrectomy. At laparotomy, we detected the lymphatic ducts using enteral nutrition of fat formulas during surgery and successfully closed the lymphatic ducts by suturing and ligation on the 38th postoperative day. Prolonged lymphorrhea causes extreme deterioration of the patient's general condition. Prolonged total parenteral nutrition also increases the risk of infection. It is important to perform surgical treatment for intractable lymphorrhea that does not improve with conservative treatment without hesitation.

Abstract
A 69-year-old man with dysphagia was diagnosed with advanced esophageal cancer by upper gastrointestinal endoscopy. He had undergone pancreatic tail and partial transverse colon resection for pancreatic cancer, and right hilar lymph node biopsy and partial lower lobe resection for the diagnosis of pulmonary sarcoidosis. Contrast-enhanced computed tomography(CT)scan showed no change over time in lymph node enlargement in the mediastinum, so metastasis of esophageal cancer was considered to be negative. Therefore, the diagnosis of advanced esophageal cancer, Mt, type 2, T2N0M0, cStage Ⅱ, was made, and surgery was performed after 2 courses of DCF therapy. Because of the adhesions in the thoracic cavity and possible problems with elevation of the gastric tube and blood flow due to resection of the pancreatic tail, it was decided to perform two-stage operation. Although imaging studies over time, as in the present case, can help in the diagnosis, it is difficult to distinguish whether enlarged lymph nodes are reactive changes or metastases. In this study, we experienced a case of thoracic esophageal cancer complicated by sarcoidosis with enlarged mediastinal lymph nodes.

Abstract
PURPOSE Although gemcitabine-based chemotherapy is most recommended for pancreatic ductal adenocarcinoma (PDAC), its effectiveness is limited because of drug resistance. Given thalidomide's anti-tumor effects in solid tumors, we investigated the effect of avadomide, a novel thalidomide analog, on PDAC and explored its anti-tumor mechanisms. METHODS PDAC cell lines, including gemcitabine-resistant (GR) clones derived from MiaPaCa2 cells, were used to evaluate the effects of avadomide. An annexin V assay, a cell cycle assay, and western blot analysis were performed to explain the mechanism of avadomide as an anti-tumor reagent. Moreover, we investigated the anti-tumor effect on tumor growth using a subcutaneous xenograft murine model. RESULTS Avadomide showed anti-tumor effects in human PDAC cell lines. The proportion of apoptotic cells and G0/G1 phase cells after avadomide treatment increased, especially in the GR PDAC clones. Western blot analysis also showed the induction of the apoptotic pathway by inhibiting the NF-κB process and G1 phase cell cycle arrest. The xenograft murine model revealed that the proportion of viable cells in the avadomide-treated group was lower than that in the untreated group. CONCLUSION Our findings suggest that avadomide could be a novel therapeutic option to overcome gemcitabine resistance in patients with PDAC.

Abstract
PURPOSE This study aimed to investigate whether clinical outcomes varied based on the tumor location within the pancreatic body and tail in patients with pancreatic cancer (PC). METHODS Ninety-five patients who had undergone a distal pancreatectomy for resectable (R) or borderline resectable (BR) PC within the pancreatic body or tail region were retrospectively investigated and divided into four groups (three subgroups of R-PC according to tumor location, and BR-PC): R-PC in the pancreatic body region (group A, n = 24), R-PC on the right side of the pancreatic tail region (group B, n = 17), R-PC on the left side of the pancreatic tail region (group C, n = 29), and BR-PC located in any region within the pancreatic body and tail (group BR, n = 25). RESULTS Group C patients showed a higher incidence of pretreatment splenic artery and vein involvement than group A and B patients (splenic artery: 8.3/11.8/41.4%, p < 0.010; splenic vein: 25.0/23.5/79.3%, p < 0.010, in groups A/B/C, respectively). The overall survival of group C patients was significantly unfavorable compared to that of group A and B patients (median: 3.9/4.2/2.3 years in groups A/B/C, p = 0.029, respectively). Pretreatment clinical factors were comparable between group C and group BR. Median survival rates were comparable between group C and BR patients (2.3 and 2.0 years, respectively) (p = 0.93). CONCLUSIONS Differences in anatomical location within the pancreatic body and tail characterize the unfavorable outcomes of PC near the splenic hilum.

Abstract
BACKGROUND Intrahepatic cholangiocarcinoma (iCCA) has a high recurrence rate and poor prognosis, and chemotherapy options are limited. The prevalence of cancer-associated fibroblasts (CAFs) in iCCA has recently emerged as a prognostic marker and therapeutic target. A method to quantify the expression of CAFs is needed; however, a simple and reliable quantification method has not yet been established. OBJECTIVE The aim of this study was to establish a simple and reliable method of quantifying CAFs. METHODS A total of 71 patients with iCCA who underwent curative resection from November 2006 to October 2020 in our hospital were investigated. Immunohistochemistry for alpha-smooth muscle actin (α-SMA) was performed and α-SMA-positive cells were quantified by an automated analysis system (new method) and visually counted (conventional method). The times required for measurement and the prognosis were compared. RESULTS The results of the quantification of CAFs by the new method were significantly correlated with the results by the conventional method, and the time required for measurement was significantly shorter with the new method. Patients with high-intensity CAFs showed a significantly poorer prognosis in terms of overall survival (OS) and the cumulative hepatic recurrence rate. In addition, high α-SMA levels were a significant risk factor for OS in multivariate analysis. CONCLUSIONS This new method may contribute to the management of patients with iCCA, not only for the prediction of prognosis of patients with iCCA, but also for the indication of targeted therapy against CAFs.

Abstract
PURPOSE In biliary tract cancer (BTC), malignancy is strongest at the invasion front. To improve the BTC prognosis, the invasion front should be controlled. We evaluated tumor-stroma crosstalk at the tumor center and at the invasion front of BTC lesions. We investigated the expression of SPARC, a marker of cancer-associated fibroblasts, and determined its ability to predict BTC prognosis after neoadjuvant chemoradiotherapy (NAC-RT). METHODS We performed immunohistochemistry to evaluate SPARC expression in resected specimens from patients that underwent BTC surgery. We established highly invasive (HI) clones in two BTC cell lines (NOZ, CCLP1), and performed mRNA microarrays to compare gene expression in parental and HI cells. RESULTS Among 92 specimens, stromal SPARC expression was higher at the invasion front than at the lesion center (p = 0.014). Among 50 specimens from patients treated with surgery alone, high stromal SPARC expression at the invasion front was associated with a poor prognosis (recurrence-free survival: p = 0.033; overall survival: p = 0.017). Coculturing fibroblasts with NOZ-HI cells upregulated fibroblast SPARC expression. mRNA microarrays showed that connective tissue growth factor (CTGF) was upregulated in NOZ-HI and CCLP1-HI cells. A CTGF knockdown suppressed cell invasion in NOZ-HI cells. Exogeneous CTGF upregulated SPARC expression in fibroblasts. SPARC expression at the invasion front was significantly lower after NAC-RT, compared to surgery alone (p = 0.003). CONCLUSION CTGF was associated with tumor-stroma crosstalk in BTC. CTGF activated stromal SPARC expression, which promoted tumor progression, particularly at the invasion front. SPARC expression at the invasion front after NAC-RT may serve as a prognosis predictor.

Abstract
BACKGROUND The isolated bile duct is sometimes observed in the right liver graft of living donor liver transplantation (LDLT). Even though, as a rescue option, it is known to use the recipient's cystic duct (CyD) for duct-to-duct anastomosis, the long-term feasibility of rescue duct-to-CyD (D-CyD) anastomosis remains unclear. METHODS We prospectively collected data in the right liver-LDLT cohort and compared rescue D-CyD anastomosis (n = 4) with standard duct-to-hepatic duct (D-HD, n = 45) anastomosis (D-CyD group, n = 4). RESULTS The observation period was over 5 years (range, 68-171 mo) after LDLT. The D-CyD group included the following anastomosis procedures: anastomosis between the intrahepatic bile duct of the graft and the CyD of the recipient and anastomosis between the posterior HD and the CyD. Surgical outcomes between the 2 groups are similar, excluding the time for the biliary reconstruction (D-CyD, 116 ± 13 min vs D-HD, 57 ± 3 min). During the period, one recipient in the D-CyD group exhibited postoperative biliary stricture and biliary stone, and 6 recipients underwent those complications in the D-HD group (D-CyD, 25.0% vs D-HD, 13.3%) All recipients in the D-CyD group are presently alive and have not experienced liver dysfunction. CONCLUSIONS Our findings suggest that rescue D-CyD anastomosis for an isolated bile duct in a right liver LDLT is acceptable as a life-saving option in terms of long-term feasibility.

Abstract
BACKGROUND No effective therapies have yet been established for liver regeneration in liver failure. Autologous skeletal myoblast cell sheet transplantation has been proven to improve cardiac function in patients with heart failure, and one of the mechanisms has been reported to be a paracrine effect by various growth factors associated with liver regeneration. Therefore, the present study focused on the effect of myoblast cells on liver regeneration in vitro and in vivo. METHODS We assessed the effect of myoblast cells on the cells comprising the liver in vitro in association with liver regeneration. In addition, we examined in vivo effect of skeletal myoblast cell sheet transplantation in C57/BL/6 mouse models of liver failure, such as liver fibrosis induced by thioacetamide and hepatectomy. RESULTS In vitro, the myoblast cells exhibited a capacity to promote the proliferation of hepatic epithelial cells and the angiogenesis of liver sinusoidal endothelial cells, and suppress the activation of hepatic stellate cells. In vivo, sheet transplantation significantly suppressed liver fibrosis in the induced liver fibrosis model and accelerated liver regeneration in the hepatectomy model. CONCLUSIONS Autologous skeletal myoblast cell sheet transplantation significantly improved the liver failure in the in vitro and in vivo models. Sheet transplantation is expected to have the potential to be a clinically therapeutic option for liver regeneration in liver failure.

Abstract
Abstract
Introduction: The analysis of CTCs as liquid biopsies provides the possibility to avoid invasive tissue biopsies, with obvious implications in cancer diagnostics and treatments. We tested new methods for v-CTCs detection in patients (pts) with pancreatic cancer (PC), and investigated the clinical potential of v-CTCs in prognosis. We analyzed the PD-L1(L1) expression in primary PC tumors, metastatic lymph nodes (LN) and v-CTCs.
Pts and Methods: 7.5 ml of venous blood was collected from 39 PC pts, either upfront surgery (U group) or pre-treatment, consisted of Gem:800mg/m2; and S-1:80mg/m2 given concurrently with IMRT to 60Gy ((NACRT:N group). To detect v-CTCs, we employed a telomerase-specific replication-selective adenovirus expressing GFP. For U group, samples were obtained before/after resection. For N group, samples were obtained before/after NACRT and after resection. To distinguish between leucocyte and cells with either epithelial or mesenchymal origin, cells were stained by anti-CD45, anti-Cytokeratin and anti-Vimentin Abs. GFP-positive and CD45-negative cells were counted as v-CTCs. To assess L1 expression in PC tissues (PC tumors and LN) and on v-CTCs, L1 IHC kit (22C3, for tissues) and anti-human L1 mAb(MIH1, for CTCs) were employed.
Results: U group: 24 pts aged 53~85 years (male/female=12/12) were enrolled. 24 pts underwent curative resection. No v-CTCs were detected in 6 pts at both before and after resection, and 5 of 6 pts survived without recurrence. V-CTCs were identified in 18 of 24 pts, and 13 of 18 pts developed liver metastasis. Marked decrease of CTC counts were seen after resection in 10 of 18 pts, but 9 pts developed recurrences. N group: 15 PC pts aged 44~77 years (male/female=4/11) were enrolled. 15 pts underwent curative resection. No v-CTCs at 3 sampling points were detected in 5 pts, and 5 pts survived without recurrences. V-CTCs was identified in 10 of 15 pts, and 4 out of 10 pts developed disease recurrence. Marked increase in CTC counts was observed after NACRT in 5 of 6 CTC-positive pts before NACRT, and 3 of 5 pts developed liver metastasis and died. NACRT may induce tumor cell dissemination into the blood circulation for CTC-positive pts. PD-L1 expression: L1 expression were assessed for 21 pts (U group:18, N group: 3). For PC tumors, L1 molecules were expressed in 12 pts and expression level of these pts were all low (57%, ≥50% [high]=0 pts, 1-49% [low]=12 pts {10%=6, 20%=4, 40%=2}, <1% [negative]=9 pts). For metastatic LNs, metastatic LNs were observed in 14 pts and L1-positive expression in these LNs were detected in only 4 pts (28%, all low expression). On the contrary, the majority of detected v-CTCs clearly expressed L1 molecule (92 CTCs out of 103 detected CTCs were L1-positive=89 %).
Conclusions: Viable CTC detection appears as a good prognostic marker. Immunotherapy with anti-PD-1/PD-L1 Abs may target v-CTCs, resulted in improvement of poor prognosis.

Abstract
BACKGROUND The change impact of body composition during neoadjuvant therapy on clinical outcomes in patients with pancreatic ductal adenocarcinoma (PDAC) remains unclear. The aim of this study was to investigate the association between changes in body composition during neoadjuvant chemoradiotherapy (NACRT) and postoperative outcomes in patients with PDAC undergoing pancreatectomy, using three-dimensional images. METHODS We reviewed 66 consecutive patients with resectable/borderline resectable PDAC receiving gemcitabine and S-1 with radiotherapy between April 2010 and June 2016. Body compositions were evaluated pre- and post-NACRT. All patients were hospitalized and supplied with regulated diet during NACRT treatment. RESULTS Psoas major muscle volume index (PMI), abdominal fat volume index, and visceral fat volume index decreased significantly after NACRT (P < 0.0001, P < 0.0001, P < 0.0001, respectively). The post-NACRT CA19-9 level decreased significantly in the small-PMI-decrease group compared with the large-PMI-decrease group (P = 0.046). Recurrence-free survival (RFS) and overall survival (OS) of the large-PMI-decrease group were significantly poorer than those of the small-PMI-decrease group (P = 0.002, P = 0.006, respectively). On the other hand, there were no significant differences in RFS and OS between groups with high and low PMI, at the point of either pre-NACRT (P = 0.117, P = 0.123, respectively) or post-NACRT (P = 0.065, P = 0.064, respectively). Multivariate analysis identified a large percentage decrease in PMI as an independent risk factor for recurrence and death (P = 0.003, P = 0.002, respectively). CONCLUSIONS Loss of skeletal muscle mass during NACRT was an independent risk factor for survival in patients with PDAC.

Abstract
Solitary colonic metastasis from esophageal cancer is rare. The prognosis of patients with distant metastases from esophageal cancer is extremely poor. A case of long-term survival with colonic metastasis from esophageal cancer treated by multimodal therapy is reported. A 67-year-old man was diagnosed with middle thoracic esophageal squamous cell carcinoma. The patient received neoadjuvant chemotherapy and then underwent subtotal esophagectomy. Approximately 1 year after esophagectomy, an asymptomatic, solitary colonic mass was detected on the follow-up computed tomography for esophageal cancer. Preoperative colonoscopy showed a 5-cm type 3 tumor at the ascending colon, and histological findings of the biopsy specimen indicated possible metastasis from primary esophageal squamous cell carcinoma. The patient underwent laparoscopic ileocolic resection with D3 lymph noddle dissection. Histologically, the colonic tumor was confirmed to be a metastasis from the esophageal squamous cell carcinoma. To the best of our knowledge, only eight cases with resected solitary colonic metastasis, including the present case, have been reported, and the present patient achieved greater than 3-year survival after esophagectomy. Resection of an asymptomatic solitary organ metastasis from primary esophageal cancer appears to be a good therapeutic option, even following esophagectomy.

Abstract
ABSTRACT Pancreatic mucinous cystic neoplasm (MCN) rarely ruptures because of their surrounding fibrotic capsules and has never been reported with detailed information regarding prerupture and postrupture states. We report a case of MCN rupture where performed emergency surgery was performed while waiting for elective surgery. A 54-year-old woman was referred to our department for a pancreatic cystic tumor with slight abdominal pain. A cystic tumor with a nodular lesion was found, with a contrast effect measuring 78 mm in diameter. On day 21, the patient visited our hospital complaining of increased abdominal pain, but few signs of peritonitis were observed. Tests conducted revealed moderate ascites, marginal shrinkage of the cyst diameter, and a slight elevation of inflammatory markers. We suspected an MCN rupture and immediately performed distal pancreatectomy. Brown turbid ascites and rupture of the anterior wall of the cyst were observed. In the ascites, amylase levels were not elevated, and bacterial cultures were negative. The histopathological diagnosis was noninvasive mucinous cystadenocarcinoma. At 9 months after surgery, she started chemotherapy because of a recurrence of the peritoneal dissemination. This case provided valuable insight into the rupture of MCNs using thorough imaging techniques, laboratory, and physical findings before and after rupturing.

Abstract
Colorectal liver metastasis (CRLM) appears in 25-50% of patients with colorectal cancer (CRC). However, CRLM with bile duct tumor thrombus (BDTT) is rare and often diagnosed after surgical resection. We report a case of CRLM associated with BDTT in a 79 year-old woman. She underwent sigmoid colectomy for sigmoid colon carcinoma at the age of 64. Fifteen years later, abdominal computed tomography revealed a liver tumor with a biliary tumor thrombus in segment IV/V and localized dilation of the intrahepatic bile duct. Additionally, magnetic resonance imaging confirmed a tumor in liver segment IV/V and mass in the bile duct (B4). Extended left hepatic lobectomy was performed under the diagnosis of intrahepatic cholangiocarcinoma or metastatic liver tumor with tumor development in the intrahepatic bile duct. The resected specimen showed significant cancer infiltration into the intrahepatic bile duct (B4), forming a tumor thrombus. The tumor was a moderately differentiated adenocarcinoma, histologically similar to sigmoid colon cancer. CRLM with BDTT may have a relatively low invasive potential of malignancy with a long interval after primary resection. When a patient with a history of CRC presents with BDTT, the possibility of CRLM with BDTT and surgical treatment should be considered, because resection could lead to a good prognosis. It is important to ensure a secure surgical margin in the bile ducts during surgery and anatomical hepatic resection should be considered.

Abstract
A 71-year-old man with pathological Stage Ⅰ(pT1bN0M0)underwent laparoscopic sigmoid colon cancer resection. After 18 months postoperatively, follow-up computed tomography(CT)showed a 30 mm enhanced soft tissue tumor near the anastomotic site. Considering the magnetic resonance imaging(MRI)and positron emission tomography(PET)results, we diagnosed sigmoid colon cancer with local recurrence. Laparoscopic radical resection of the colon and intestine, including the tumor, was performed. Pathologically, the tumor comprised spindle-shaped cells with collagen fibers and was diagnosed as a desmoid tumor by immunostaining(β-catenin+, c-kit-, CD34-, α-SMA-, and DOG-1-). We report a case of intra-abdominal desmoid tumor near the anastomotic site after laparoscopic sigmoid colon cancer resection.

Abstract
BACKGROUND Advanced gastric cancer with peritoneal dissemination is difficult to treat, although prognosis has improved with chemotherapy and the introduction of molecular targeted drugs. CASE A 65-year-old male was diagnosed as type 3 advanced gastric cancer on the posterior wall of antrum by esophagogastroduodenoscopy for anemia screening. When the patient underwent radical surgery, multiple disseminated nodules(P1c)were detected. After chemotherapy(SOX, PTX plus RAM)was administered, the tumor shrank, and staging laparoscopy was performed. Since disseminated nodules have disappeared, distal gastrectomy(R0)was performed as conversion surgery. As postoperative adjuvant chemotherapy, S-1 was administered for about 1 year and 6 months. During repair of incisional hernia at 1 year postoperatively, the patient was confirmed to have no disseminated recurrence. The patient is currently alive with no sign of recurrence for 4 years.

Abstract
Extensive gastrointestinal surgery surveillance data in Japan were analyzed to examine the differences in the risk factors for surgical site infection (SSI) between laparotomy and laparoscopic abdominal procedures. Surgical procedures investigated in the study were gastrectomy, cholecystectomy, colectomy, rectal resection, and appendectomy. A total of 32,629 patients were included in the study. The study participants were divided into two groups according to the year of surgery, 2003–2009 (first study period) and 2010–2015 (second study period), due to the increase in the number of laparoscopic surgeries in the second study period. The incidence of SSI was stratified by three SSI classifications (superficial incisional, deep incisional, and organ/space SSI). Multiple logistic regression analysis was performed to predict the risk factors for SSI. The percentage of laparoscopic surgeries performed has increased linearly since 2010. Patients in the second study period were significantly older and had a higher prevalence of SSI risk factors compared with those in the first study period. In addition, the predictive factors changed substantially in most surgical procedures between the two study periods. Wound class ≥ 3 was a ubiquitous risk factor for superficial incisional SSI (SI-SSI) and organ/space SSI (OS-SSI) in both open (laparotomy) and laparoscopic procedures in the first study period. Meanwhile, in the second study period, operative duration was a ubiquitous risk factor in both procedures. The risk factors for SI-SSI differed from those for OS-SSI in the five abdominal surgeries investigated in the study. Periodic examination of risk factors for SSI is recommended in an aging society.

Abstract
Abstract
Background
SMAD4 is a key mediator of TGFβ signaling and one of the mutated genes in extrahepatic bile duct cancer (eBDC). It has been also reported that SMAD4 has dual functions, in carcinogenesis via silencing and in tumor invasion/metastasis via signaling, depending on tumor stage. We previously visualized more nuclear transitioning functional SMAD4 at the tumor invasion front than the central lesion. So, we investigated the localization of functional SMAD4 (e.g., invasion area or metastasis lesion) and its association with chemotherapy and chemo-radiation therapy.
Methods
We performed SMAD4 immunostaining on 98 resected eBDC specimens and evaluated the presence of the functional form of nuclear SMAD4 at the central lesion, invasion front, and metastatic lymph node. We also examined the influence on chemotherapy after recurrence (n = 33) and neoadjuvant chemo-radiation therapy (NAC-RT, n = 21) and the prognostic value of using retrospective data.
Results
In 73 patients without NAC-RT, 8.2% had loss of SMAD4 expression and 23.3% had heterogeneous expression. Patients without SMAD4 expression at any site had significantly poorer overall survival (OS) than other patients (P = 0.014). Expression of SMAD4 at the invasion front was related to better survival (recurrence-free survival [RFS] P = 0.033; OS P = 0.047), and no SMAD4 expression at the metastatic lymph node was related to poorer OS (P = 0.011). The patients who had high SMAD4 expression had poorer prognosis after recurrence (RFS P = 0.011; OS P = 0.056). At the residual cancer in the resected specimen, SMAD4 was highly expressed after NAC-RT (P = 0.039).
Conclusions
Loss of SMAD4 protein expression was a poor prognostic factor in eBDC at resectable stage. However, the intensity of functional SMAD4 in eBDC is a marker of resistance to chemo-radiotherapy and malignant potential at advanced stages.

Abstract
BACKGROUND The outcome of pancreatic ductal adenocarcinoma (PDAC) is unsatisfactory, and the identification of novel therapeutic targets is urgently needed. Clinical studies on the antisense oligonucleotide that targets clusterin (CLU) expression have been conducted and have shown efficacy in other cancers. We aimed to investigate the effects of CLU in PDAC and the underlying mechanisms with a view to the clinical application of existing drugs. METHODS We knocked down CLU in PDAC cells and evaluated changes in cell proliferation. To elucidate the mechanism responsible for these changes, we performed western blot analysis, cell cycle assay, and senescence-associated β-galactosidase (SA-β-gal) staining. To evaluate the clinical significance of CLU, immunohistochemistry was performed, and CLU expression was analyzed in specimens resected from PDAC patients not treated with preoperative chemotherapy. RESULTS Knockdown of CLU significantly decreased cell proliferation and did not induce apoptosis, but did induce cellular senescence by increasing the percentage of G1-phase and SA-β-gal staining-positive cells. A marker of DNA damage such as γH2AX and factors related to cellular senescence, such as p21 and the senescence-associated secretory phenotype, were upregulated by knockdown of CLU. CLU expression in resected PDAC specimens was located in the cytoplasm of tumor cells and revealed significantly better recurrence-free survival and overall survival in the CLU-low group than in the CLU-high group. CONCLUSIONS We identified that CLU inhibition leads to cellular senescence in PDAC. Our findings suggest that CLU is a novel therapeutic target that contributes to the prognosis of PDAC by inducing cellular senescence.

Abstract
BACKGROUND Combined hepatocellular and cholangiocarcinoma is a rare primary liver cancer with histological features of both hepatocellular carcinoma and intrahepatic cholangiocarcinoma. Little is known about the prognostic features and molecular mechanism of cHCC-iCCA. Acylphosphatase 1 is a cytosolic enzyme that produces acetic acid from acetyl phosphate and plays an important role in cancer progression. AIMS We evaluated the clinical significance of ACYP1 expression in cHCC-iCCA, HCC, and iCCA. METHODS ACYP1 immunohistochemistry was performed in 39 cases diagnosed with cHCC-iCCA. The prognosis was evaluated in three different cohorts (cHCC-iCCA, HCC, and iCCA). The relationships between ACYP1 expression and cell viability, migration, invasiveness, and apoptosis were examined using siRNA methods in vitro. In vivo subcutaneous tumor volumes and cell apoptosis were evaluated after downregulation of ACYP1 expression. RESULTS Almost half of the patients with cHCC-iCCA were diagnosed with high ACYP1 expression. In all three cohorts, the cases with high ACYP1 expression had significantly lower overall survival, and high ACYP1 expression was identified as an independent prognostic factor. Downregulation of ACYP1 reduced the proliferative capacity, migration, and invasiveness of both HCC and iCCA cells. Moreover, knockdown of ACYP1 increased the ratio of apoptotic cells and decreased the expression of anti-apoptosis proteins. In vivo tumor growth was significantly inhibited by the transfection of ACYP1 siRNA, and the number of apoptotic cells increased. CONCLUSION High ACYP1 expression could influence the prognosis of cHCC-iCCA, HCC, and iCCA patients. In vitro ACYP1 expression influences the tumor growth and cell viability in both HCC and iCCA by regulating anti-apoptosis proteins.

Abstract
INTRODUCTION Subtotal cholecystectomy (STC) has become recognized as a "bailout procedure" to prevent bile duct injury in patients undergoing laparoscopic cholecystectomy (LC). Predictors of conversion to STC have not been identified because LC difficulty varies based on pericholecystic inflammation. We analyzed data from patients enrolled in a previously performed multi-institutional retrospective study of the optimal timing of LC after gallbladder drainage for acute cholecystitis (AC). These patients presumably had a considerable degree of pericholecystic inflammation. METHODS In total, 347 patients who underwent LC after gallbladder drainage for AC were analyzed to examine preoperative and perioperative factors predicting conversion to STC. RESULTS Three hundred patients underwent total cholecystectomy (TC) and 47 underwent conversion to STC. Eastern Cooperative Oncology Group Performance Status (ECOG PS) (P < .01), severity of cholecystitis (P = .04), previous history of treatment for common bile duct stones (CBDS) (P < .01), and surgeon experience (P = .03) were significantly associated with conversion to STC. Logistic regression analyses showed that ECOG PS (odds ratio 0.2; P < .0001) and previous history of treatment for CBDS (odds ratio 0.37; P = .0073) were independent predictors of conversion to STC. Our predictive risk score using these two variables suggested that a score ≥2 could discriminate between TC and STC (P < .0001). CONCLUSION Poor ECOG PS and previous history of treatment for CBDS were significantly associated with conversion to STC after gallbladder drainage for AC.

Abstract
BACKGROUND Intraductal papillary mucinous neoplasms (IPMNs) are typically detected as incidental findings by computed tomography (CT); however, the conventional surveillance is not valid for the early detection of concomitant pancreatic cancer. The pancreas of IPMN is often accompanied by fatty infiltration in the parenchyma, and pancreatic fatty infiltration could be evaluated by pancreatic CT density (pancreatic index, PI). We aimed to investigate whether PI could be an imaging biomarker for the early prediction of malignancies in the pancreas with IPMN. METHODS Two different cohorts were investigated. (Investigation cohort): A total of 1137 patients with initially low-risk IPMN were compensated by initial IPMN findings, and 2 groups (malignancy/possible benign, 50 cases each) were investigated for yearly changes in PI and for the cutoff value of PI indicating the development of malignancies. (Validation cohort): To validate the cutoff value, 256 patients radiologically suspected of having IPMNs were investigated. RESULTS (Investigation-cohort): The malignancy group showed a gradual decrease in PI every year, and PI significantly differed among the 2 groups 1 year prior to the last investigation. The cutoff value of PI was set at 0.65. (Validation-cohort): A total of 55% of the patients with a PI below the cutoff value had malignancy in the pancreas, including concomitant pancreatic cancer, and the cutoff value was the most significant risk factors for the development of malignancies in the pancreas compared to the conventional risk factors for IPMN. CONCLUSIONS Decreasing PI would be an optimal imaging biomarker for earlier detection of malignancies in the pancreas with IPMN.

Abstract
Tumor endothelial cells (TECs) promote tumor angiogenesis and regulate cytotoxic T cells in the tumor microenvironment. However, the roles of TECs for tumor‐infiltrating T‐cell in hepatocellular carcinoma (HCC) is still unknown. Here, we aimed to investigate how TECs influenced tumor growth and immune responses of HCC focusing on CD8+ T‐cell infiltration and exhaustion. First, TECs were isolated from subcutaneous HCC tumors with murine HCC cell lines (BNL‐T) with magnetic selection of CD31+ cells, and normal endothelial cells (NECs) were isolated from normal liver. Second, immunocompetent mice were injected with BNL‐T alone, BNL‐T + NECs, or BNL‐T + TECs for tumor formation, and the functions and exhaustion of tumor‐infiltrating CD8+ T cells were evaluated. The mice injected with BNL‐T + TEC showed rapid tumorigenesis and a decrease in the number of infiltrating CD8+ T cells. In addition, the percentage of CD8+ T‐cell exhaustion was significantly higher in tumors from the administration of BNL‐T + TEC. Third, the next‐generation sequencing on TECs was performed to identify mRNAs that might be a novel treatment target. The molecule of glycoprotein nonmetastatic melanoma protein B (GPNMB) was identified and the functions of GPNMB was analyzed by silencing of GPNMB expression using small interfering RNAs. The silencing of GPNMB expression in TECs induced the suppression of tumor growth and T‐cell exhaustion. In conclusion, TECs induced tumor‐infiltrating T‐cell exhaustion via GPNMB expression and GPNMB might be a novel therapeutic target in HCC.

Abstract
Background and Aim Bacterial infection is involved in the progression of many gastrointestinal diseases, including those of pancreas; however, how and which bacteria colonize in pancreatic juice and tissue have yet to be elucidated. Recently, we reported that Enterococcus faecalis exists in the pancreatic juice and tissues of patients with chronic pancreatic disease. Here, we investigated the survival of E. faecalis in duodenal juice with different pH conditions. Methods Pancreatic juice samples from 62 patients with cancers of the duodeno‐pancreato‐biliary region were evaluated for the presence of E. faecalis. 16S ribosomal RNA polymerase chain reaction and 16S‐based metagenome analyses were performed to determine the bacterial composition. The survival of E. faecalis in various pancreatic juice conditions was evaluated. Results Of 62 samples, 27% (17/62) were positive for Enterococcus spp., among which 71% (12/17) contained E. faecalis. Enterococcus spp. showed the highest fitness for survival in alkaline pancreatic juice among various bacterial species. The microbiome of pancreatic juice from patients with pancreatic and bile duct cancer showed diversity, but Enterococcus spp. were enriched among duodenal tumors and intraductal papillary mucinous neoplasms. Conclusions Alkalinity is one of the important factors for the selective survival of E. faecalis among microbiota. E. faecalis can colonize the pancreatic duct when the pancreatic juice condition is altered.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease, and multimodal strategies, such as surgery plus neoadjuvant chemotherapy (NAC)/adjuvant chemotherapy, have been attempted to improve survival in patients with localized PDAC. To date, there is one prospective study providing evidence for the superiority of a neoadjuvant strategy over upfront surgery for localized PDAC. However, which NAC regimen is optimal remains unclear. METHODS A randomized, exploratory trial is performed to examine the clinical benefits of two chemotherapy regimens, gemcitabine plus S-1 (GS) and gemcitabine plus nab-paclitaxel (GA), as NAC for patients with planned PDAC resection. Patients are enrolled after the diagnosis of resectable or borderline resectable PDAC. They are randomly assigned to either NAC regimen. Adjuvant chemotherapy after curative resection is highly recommended for 6 months in both arms. The primary endpoint is tumor progression-free survival time, and secondary endpoints include the rate of curative resection, the completion rate of protocol therapy, the recurrence type, the overall survival time, and safety. The target sample size is set as at least 100. DISCUSSION This study is the first randomized phase II study comparing GS combination therapy with GA combination therapy as NAC for localized pancreatic cancer. TRIAL REGISTRATION UMIN Clinical Trials Registry UMIN000021484 . This trial began in April 2016.

Abstract
As a treatment option for PDAC, radiation therapy induces good local control. However, radiation also reportedly enhances the malignant potential (e.g., invasion and migration ability) in various cancers, thus increasing the risk of distant metastasis. It remains unclear how radiation induces malignant potential, and how such enhanced malignant potential can be suppressed. In the current study, we evaluated the sequential change of c-Met expression in pancreatic cancer cells following irradiation. We found that irradiation transiently induced c-Met expression in vitro. In an in vivo subcutaneous tumor mouse model, irradiation also enhanced downstream phosphorylated Met (p-Met). Furthermore, this enhancement of p-Met protein expression was suppressed by oral administration of the c-Met inhibitor INC280. Irradiated pancreatic cancer cells with enhanced c-Met expression exhibited higher malignant potential, including invasion and migration ability, compared with cells showing low c-Met expression. Pancreatic cancer cells that overexpressed c-met also showed enhanced malignant potential, which was reversed by c-Met inhibition. Additionally, c-Met inhibitor suppressed the metastatic potential in a liver metastasis mouse model using c-met-overexpressing cells. Overall, our present results revealed that irradiation could induce c-met expression in pancreatic cancer cells, leading to enhanced malignant potential (e.g., invasion and migration ability) and thus promoting distant metastasis. Moreover, a c-Met inhibitor could reverse this enhanced malignant potential.

Abstract
Abstract
[Introduction] CTCs as liquid biopsy are an emerging minimally invasive tool for cancer diagnosis, surveillance, and treatment. We tested novel methods for viable CTCs (v-CTC) isolation in the patients (pts) with pancreatic cancer (PC), and investigated the clinical potential of v-CTCs in prognosis. Furthermore, we analyzed the PD-L1(L1) expression in primary PC tumors, metastatic lymph nodes (LN) and v-CTCs.
[Pts and Methods] 7.5 ml of venous blood was collected prospectively from 39 PC pts, either upfront surgery (Up group) or pre-treatment, consisted of Gem:800 mg/m2; and S-1:80 mg/m2 given concurrently with IMRT to 60 Gy (NACRT:N group). To detect v-CTCs, we employed a telomerase-specific replication-selective adenovirous expressing GFP. For Up group, samples were obtained before/after resection. For N group, samples were obtained before/after NACRT and after resection. To distinguish between leucocyte and cells with either epithelial or mesenchymal origin, cells were stained by anti-CD45, anti-Cytokeratin and anti-Vimentin Abs. GFP-positive and CD45-negative cells were counted as v-CTC. To assess L1 expression in PC tissues (PC tumors and LN) and v-CTCs, L1 IHC kit (22C3, for tissues) and anti-human L1 mAb (MIH1,for CTCs) were employed.
[Results] Up group: 24 pts aged 53~85 years (male/female=12/12) were enrolled. 24 pts underwent curative resection. No v-CTCs were detected in 6 pts at both before and after resection, and 5 of 6 pts survived without recurrence. V-CTCs were identified in 18 of 24 pts, and 13 of 18 pts developed liver metastasis. Marked decrease of CTC counts were seen after resection in 10 of 18 pts, but 9 pts developed recurrence. N group: 15 PC pts aged 44~77 years (male/female=4/11) were enrolled. 15 pts underwent curative resection. No v-CTCs were detected in 5 pts, and all 5 pts survived without recurrence. V-CTCs was identified in 10 of 15 pts, and only 3 out of 10 pts developed disease recurrence. Marked increase in CTC counts was observed after NACRT in 5 of 6 CTC-positive pts before NACRT, and 3 of 5 pts developed liver metastasis and died. RT may induce tumor cell dissemination into the blood circulation for CTC-positive pts. PD-L1 expression: L1 expression were assessed for 21 pts (Up group:18, N group: 3). For PC tumors, L1 molecules were expressed in 12 pts and expression level of these pts were all low (57%, ≥50% [high]=0 pts, 1-49% [low]=12 pts {10%=6, 20%=4, 40%=2}, <1% [negative]=9 pts). For metastatic LNs, metastatic LNs were observed in 14 pts and L1-positive expression in these LNs were detected in only 4 pts (28%, all low expression). On the contrary, the majority of detected v-CTCs clearly expressed L1 molecule (92 CTCs out of 103 detected CTCs were L1-positive=89 %).
[Conclusions] Viable CTC detection appears as a promising prognostic marker. Immunotherapy with anti-PD-1/PD-L1 Abs may effectively target v-CTCs to evade recurrence.

Abstract
BACKGROUND We aimed to clarify usefulness of the modified Frailty Index 11 (mFI-11) for assessing risk of postoperative complications (POCs) and effectiveness of perioperative management team (POMT) intervention for improving postoperative status of frail aged patients requiring colorectal cancer (CRC) surgery. METHODS We compared, retrospectively, surgical outcomes among 151 consecutive CRC surgery patients aged ≥80 years. Patients were grouped by mFI-11 scores and by POMT intervention (vs. no POMT intervention). RESULTS POCs were more prevalent, postoperative stays were longer, and discharge status was poorer among high-risk (mFI-11 ≥ 3/11) patients without POMT intervention than among low-risk (mFI-11 ≤ 2/11) patients (p = 0.04, p = 0.02, p < 0.01). Multiple POCs occurred less frequently and performance of activities of daily living was better for high-risk patients with (vs. those without) POMT intervention (p = 0.04, p = 0.03). CONCLUSION POMT intervention appears beneficial for frail aged patients scheduled for CRC surgery.

Abstract
A 69-year-old man presented to our hospital with chief complaints of epigastral pain and nausea, was diagnosed with intestinal obstruction after gastric surgery. Abdominal CT performed on the admission showed the tumor located on the terminal ileum. On colonoscopy, type 1 cancer was found near the Bauhin valve in the ileum, and suspected primary ileal carcinoma. Laparoscopic ileocecal resection was performed. The pathological diagnosis was moderately differentiated adenocarcinoma, and the pathological stage was T3(SS), N1(3/16), M0, Stage ⅢA. Although superficial surgical site infection was occurred, the patient was discharged 11 days after surgery. He hoped to adopt without adjuvant chemotherapy, so he has been followed as outpatient. Twenty one months since the surgery, there has been no evidence of cancer recurrence.

Abstract
Hepatocellular carcinoma (HCC) is the second leading cause of cancer‐related death. High recurrence rates after curative resection and the lack of specific biomarkers for intrahepatic metastases are major clinical problems. Recently, exosomal microRNAs (miRNAs) have been reported to have a role in the formation of the pre‐metastatic niche and as promising biomarkers in patients with malignancy. Here we aimed to clarify the molecular mechanisms of intrahepatic metastasis and to identify a novel biomarker miRNA in patients with HCC. A highly intrahepatic metastatic cell line (HuH‐7M) was established by in vivo selection. HuH‐7M showed increased proliferative ability and suppression of apoptosis and anoikis. HuH‐7M and the parental cell (HuH‐7P) showed the similar expression of epithelial‐mesenchymal transition markers and cancer stem cell markers. In vivo, mice treated with exosomes derived from HuH‐7M showed increased tumorigenesis of liver metastases. Exosomes from HuH‐7M downregulated endothelial cell expression of vascular endothelial‐cadherin (VE‐cadherin) and zonula occludens‐1 (ZO‐1) in non‐cancerous regions of liver and increased the permeability of FITC‐dextran through the monolayer of endothelial cells. The miRNAs (miR‐638, miR‐663a, miR‐3648, and miR‐4258) could attenuate endothelial junction integrity by inhibiting VE‐cadherin and ZO‐1 expression. In patients with HCC, higher serum exosomal miR‐638 expression was associated with tumor recurrence. In conclusion, the miRNAs secreted from a highly metastatic cancer cell can promote vascular permeability via downregulation of endothelial expression of VE‐cadherin and ZO‐1. Serum exosomal miR‐638 expression holds potential for serving as a significant and independent prognostic marker in HCC.

Abstract
Glycolysis emerges as a new therapeutic target for malignancies. The inhibition of glycolytic activator, PFKFB3, repairs tumor endothelial cell function, and normalizing the tumor microenvironment. We aimed to investigate the significance of PFKFB3 in HCC, and the effects of the PFKFB3 inhibitor, PFK15, in HCC tumor cells and tumor endothelial cells. Double immunofluorescent staining of PFKFB3 and CD31 in HCC tissues revealed that high PFKFB3 expression in both tumor cells and tumor endothelial cells was significantly correlated with poor prognosis. Multivariate analysis identified PFKFB3 expression as an independent prognostic factor. PFK15 suppressed proliferation of HCC cell line and tumor endothelial cells in vitro. In a subcutaneous tumor model of the HCC cell line with tumor endothelial cells, PFK15 suppressed tumor growth and induced apoptosis. Moreover, PFK15 treatment induced tumor vessel normalization, decreasing vessel diameter with pericyte attachment and improving vessel perfusion. High PFKFB3 expression in both tumor cells and tumor endothelial cells was identified as a novel prognostic marker in HCC. Targeting PFKFB3 via PFK15 might be a promising strategy for suppressing tumor growth and inducing tumor vessel normalization.

Abstract
BACKGROUND/AIM We previously demonstrated that inflammatory cytokine interleukin-6 (IL-6) was produced during cancer progression, worked together with transforming growth factor-beta 1 (TGF-β1), and induced the epithelial-mesenchymal transition (EMT) with chemo-resistance against gemcitabine (GR) at the invasion front of biliary tract cancers (BTCs). However, the significance of cytokine-induced T cell accumulation at the tumor microenvironment in biliary tract cancer (BTC) is not well understood. Because these cytokines (IL-6 and TGF-β1) are able to differentiate naïve T cells into Foxp3-expressing T cells (Tregs) and/or IL-17-producing T helper 17 (Th17) cells, we investigated the relationship between heterogeneous, cancer-producing cytokines and T cell differentiation. METHODS In total, 127 curative resected specimens from patients with BTCs at Osaka University Hospital between 2000 and 2012 were evaluated for IL-6, TGF-β1, Tregs, and Th17 cells by immunohistochemistry. The ability of BTC-GR cells to undergo T cell differentiation was investigated in vitro. RESULTS Tregs accumulated at the tumor center and Th17 cells accumulated at the invasion front during cancer progression and/or metastasis; each signaled poor prognosis. Treg accumulation was related to TGF-β1 expression by cancer cells, and Th17 cell accumulation was related to IL-6 expression by cancer cells, in resected specimens; this was confirmed in vitro. Compared with parent cells, GR cells produced IL-6 but not TGF-β1 in a time-dependent manner, had EMT features, and induced T cell differentiation to Th17 cells but not Tregs. CONCLUSION Cytokines produced by cancer cells (IL-6 and TGF-β1) induced heterogeneity of Tregs and Th17 cells in the tumor microenvironment, supporting progression of BTC.

Abstract
Abstract
Pancreatic cancer (PC) is one of the leading causes of cancer-related mortality worldwide. Although surgical resection is the only curable option, less than 20% of the patients diagnosed with localized disease are resectable. The prognosis of these patients after complete resection is extremely poor due to local and systemic recurrence. Peritoneal recurrence is a major recurrence pattern after surgery for PC. Peritoneal lavage cytology (CY) is used widely in the diagnosis and staging of gastric and pancreatic cancer to rule out patients with occult peritoneal metastasis. For gastric cancer, positive cytology (CY+), even in the absence of visible peritoneal metastasis, represents stage IV disease. However, the prognostic significance of CY+ in potentially resectable PC is controversial. We rise the question of whether CY+ status in PC has predictive value for survival and early peritoneal recurrence. Therefore, we conducted this study to evaluate use of a new genetically modified telomerase-specific replication-selective adenovirus, expressing GFP (TelomeScan F35) in rapid detection of viable peritoneal tumor cell (v-PTC) dissemination of PC. This human clinical trial sought to determine if the presence of virally-detected, rare v-PTC predict peritoneal recurrence and patient outcome. This study was approved by the IRB in Osaka Police Hospital and Rinku General Medical Center. Patients with resectable cytologically or histologically proven ductal adenocarcinoma of the pancreas were enrolled. Peritoneal lavage fluid was harvested just after a laparotomy in 53 patients with PC. Half of the fluid was examined by cytology with papanicolau staining and MOC-31 immunostaining and the remaining half was analyzed to detect v-PTC with TelomeScan F35. To distinguish between leucocyte and cells with epithelial origin, cells were stained with anti-CD45 Ab. To further distinguish cells with primary tumor origin, cells were labeled with anti-CEA, anti-CA19-9 and EpCAM Abs. GFP-positive and CD45-negative, and either CEA-, CA19-9 or EpCAM-positive cells were counted as v-PTC by automatic detection system using NIS Elements imaging software. Patients were followed after surgery to evaluate its clinical significance. Among 53 patients aged 53-87 years (30 males and 23 females), 6 were cytologically positive (CY+), other 12 were virally positive by TelomeScan F35 (v-PTC+). All 53 patients underwent a surgical resection (PD/DP/TP=32/14/7). 2 patients were double positive (CY+/v-PTC+), and peritoneal recurrence early occurred at 7 month after surgery despite adjuvant chemotherapy. 4 were CY+, but v-PTC-, and no peritoneal recurrence were observed (0%). On the other hand, other 10 were CY-, but v-PTC+, and 4 of these 10 patients occurred peritoneal recurrence (40%). Remaining 37 patients were double negative (CY-/v-PTC-), peritoneal recurrence were observed in only 4 patients. In conclusion, the TelomeScan F35-based v-PTC(+) status was associated with a significantly increased incidence of peritoneal recurrence in patients with resectable PC, resulting in impaired survival.

Abstract
BACKGROUND Small bowel obstruction (SBO) arises on various backgrounds, and the surgical procedure is often modified intraoperatively as needed. Single-incision laparoscopic surgery (SILS) is less invasive than conventional multiport laparoscopic surgery (MPS) and reported to be equally safe and efficient. We have been applying SILS to SBO requiring surgical treatment, and we conducted a retrospective study to clarify the role of SILS in the management of SBO. METHODS Thirty-four consecutive patients were identified for inclusion in the study through a review of hospital records of patients having undergone surgery for SBO between May 2013 and June 2018. Patients with tumor- or hernia-related SBO were excluded. We also identified, for comparison, a group of patients who had undergone open surgery for SBO during the preceeding 5-year period. The primary study endpoint was the SILS completion rate, and analyses were performed to identify risk factors for conversion to open surgery and perioperative complications. RESULTS The SILS completion rate was 70.6% (24/34 patients), with conversion open surgery required for the remaining 10 (29.4%) patients. Conversion was necessitated by limited working space in 5 (50%) patients, discovery of massive necrosis in 3 (30%), and non-detection of the responsible lesion in 2 (20%). Univariable analysis showed an American Society of Anesthesiologists Physical Status score (p = 0.020) and severe intra-abdominal adhesions (p = 0.007) to be risk factors for conversion. Conversion to open surgery (vs complete SILS) was significantly associated with increased operation time (p = 0.018), blood loss (p = 0.021), postoperative stay (p = 0.010), and postoperative complications (p = 0.004). Open surgery was significantly associated with increased postoperative stay (p = 0.026) and postoperative complications (p = 0.011). CONCLUSION SILS appears to be a reasonable surgical treatment option for selected patients with SBO.

Abstract
PURPOSE This study aimed to identify prognostic factors for patients with ICC after a curative resection and clarify the appropriate indications for surgical resection and postoperative adjuvant chemotherapy. METHODS This retrospective study included 81 patients who underwent curative resection for ICC between April 1995 and December 2014. Kaplan-Meier and Cox regression models were used to analyze the effects of clinicopathological features on overall and recurrence-free survival. RESULTS The cumulative 5-year overall survival of 81 patients was 57.2%, and the 5-year recurrence-free survival was 24.0%. The multivariate analysis identified the lymph node status and preoperative CA19-9 levels as independent prognostic factors for overall survival. The 5-year overall survival rates were 79.9% and 38.7% in patients with normal and elevated CA19-9, respectively (p < 0.0001). The 5-year overall survival rates of patients with and without nodal metastasis were 33.7% and 60.9%, respectively (p = 0.0007). After adjusting for prognostic factors identified in a Cox regression analysis, we found that nodal-positive disease was significantly associated with benefit from adjuvant chemotherapy (HR 0.32, p = 0.03). CONCLUSIONS Surgical resection with curative intent combined with regional lymph node dissection should be indicated for ICC patients with normal CA19-9 levels. Postoperative adjuvant chemotherapy should be administered to high-risk patients with a positive nodal status.

Abstract
A 67-year-old woman presented with bloody stools to a local physician. Lower gastrointestinal endoscopy revealed a type 3 all-circumferential tumor at descending colon. She was diagnosed with descending colon cancer and referred to our hospital for surgery. Preoperative computed tomography(CT)revealed a horseshoe kidney. We performed single-incision laparoscopic colectomy for descending colon cancer(cT3cN0cM0, cStageⅡa)complicated by a horseshoe kidney. The surgery was performed safely without any additional injuries. In patients with horseshoe kidneys, abnormalities have been reported in the running of the blood vascular system and the renal pelvis and ureter systems. Thus, sufficient understanding of the anatomic abnormality by preoperative examinations, such as 3D-CT, is essential for performing surgery safely.

Abstract
BACKGROUND CD36, a multi-ligand scavenger receptor, has been associated with several cancers. Many studies have revealed that CD36 contributed to cancer malignancy. This study aimed to reveal the function of CD36 expression in pancreatic ductal adenocarcinoma (PDAC). METHODS CD36 expression was characterized using immunohistochemistry in 95 clinical specimens resected from patients with PDAC. We divided patients into two groups, with different CD36 expression levels, and analyzed and compared their prognoses. CD36 expression was also assessed in PDAC cell lines. Gemcitabine-resistant (GR) PDAC cell lines were transfected with small interfering RNA (siRNA) that specifically targeted CD36 to evaluate chemoresistance and apoptosis. RESULTS In resected PDAC samples, CD36 expression was significantly correlated with microinvasion into the venous system (p = 0.0284). Patients with high CD36 expression had significantly lower overall survival (OS) and recurrence-free survival (RFS) rates than patients with low expression; thus, CD36 was an independent prognostic factor for OS and RFS. In subgroup analyses, CD36 was an independent risk factor for OS and RFS in 59 patients treated with gemcitabine adjuvant chemotherapy. CD36 expression was upregulated in PDAC-GR cell lines compared with the PDAC parent cell line. Transduction with siRNA downregulated CD36, which reduced PDAC cell resistance to gemcitabine and inhibited anti-apoptosis proteins. CONCLUSION CD36 expression influenced gemcitabine resistance by regulating anti-apoptosis proteins. High CD36 expression was a significant, unfavorable prognostic factor in PDAC. Anti-CD36 treatment might serve as an optional treatment for lowering resistance to gemcitabine.

Abstract
The standard treatment for unresectable or recurrent gastrointestinal stromal tumor(GIST)is tyrosine kinase inhibitor(TKI). It is reported that resection of metastatic lesions after TKI administration prolongs progression free survival, but its influence on overall survival is not clarified. We experienced a case of GIST with peritoneal dissemination for which TKI administration and 2 local resections were effective. The patient was a man in his 70's. We started chemotherapy with imatinib for GIST with peritoneal dissemination. However, it was discontinued due to the occurrence of interstitial pneumonia. Dissemination was evaluated as radically resectable on the images. After the interstitial pneumonia was alleviated, surgery was performed. Although sunitinib was introduced at 2 months postoperatively, recurrent peritoneal dissemination was detected at 32 months postoperatively, and treatment was then changed to regorafenib. Regorafenib treatment reduced the tumor size; however, Grade 3 albuminuria was detected 16 months after treatment initiation and, thus, this treatment was discontinued. Subsequently, the tumor enlarged again. Because there was only 1 recurrent lesion, we performed radical resection. Postoperatively, a reduced dose of regorafenib was re-administered. At present, 9 months after the re-surgery, the patient is alive without recurrence.

Abstract
A 66-year-old woman admitted for nausea was found to have a type 2 tumor with stenosis at the fourth portion of the duodenum by upper gastrointestinal series and endoscopy, which was diagnosed as an adenocarcinoma by endoscopic biopsy. Abdominal computed tomography(CT)showed an irregular thick wall at the fourth portion of the duodenum but without metastasis or invasion to the adjacent vessels. We examined the lymph nodes around the pancreatic head intraoperatively and partially resected the duodenum and jejunum based on the diagnosis of negative swollen nodes. The definitive diagnosis was primary tubular adenocarcinoma of the fourth portion of the duodenum, T3, N0, M0, Stage ⅡA. Reports of primary cancer of the fourth portion of the duodenum are very rare, and we include a discussion of the current literature.

Abstract
Chemoradiation was performed at Osaka Police Hospital's department of respiratory medicine on a 70-year-old male with small cell lung carcinoma(cT4N3M0, cStage ⅢC). Subsequent to secondary chemotherapy for multiple bone metastases that had been observed, he received care to control the disease. He arrived at the hospital complaining of epigastric pain. He got CT-scan and was referred to our department because of a suspected hematoma around the right gastroepiploic artery. He was treated conservatively because circulatory dynamics were steady and there was no indication that anemia had progressed. However, when a test laparotomy was performed the day after the start of treatment because he presented with decreased blood pressure and progressive anemia, a massive hematoma was found around the right gastroepiploic artery. The hematoma was removed, and hemostasis was performed. Based on the pathological findings of the excised specimen, he was diagnosed with abdominal metastasis of small cell lung carcinoma. This is a report on our experience and a literature review on a case of mesenteric hematoma caused by abdominal metastasis of small cell lung carcinoma.

Abstract
A 75-year-old man presented with a fever. Computed tomography revealed a 10 cm solid tumor under the duodenum. A pre-operative diagnosis of liposarcoma was established using biopsy. Pancreaticoduodenectomy was performed, and the pathological examination led to the diagnosis of dedifferentiation type liposarcoma. Two years later, the liposarcoma recurred at the remnant pancreas. A total remnant pancreatectomy was performed. The pathological examination revealed dedifferentiated type liposarcoma and positive surgical margins. Therefore, radiotherapy of 59.4 Gy in 33 fractions was performed at the recurrence area. The patient has been recurrence-free from 1 year 6 months since the second operation.
