Abstract
Midbrain dopamine neurons impact neural processing in the prefrontal cortex (PFC) through mesocortical projections. However, the signals conveyed by dopamine projections to the PFC remain unclear, particularly at the single-axon level. Here, we investigated dopaminergic axonal activity in the medial PFC (mPFC) during reward and aversive processing. By optimizing microprism-mediated two-photon calcium imaging of dopamine axon terminals, we found diverse activity in dopamine axons responsive to both reward and aversive stimuli. Some axons exhibited a preference for reward, while others favored aversive stimuli, and there was a strong bias for the latter at the population level. Long-term longitudinal imaging revealed that the preference was maintained in reward- and aversive-preferring axons throughout classical conditioning in which rewarding and aversive stimuli were paired with preceding auditory cues. However, as mice learned to discriminate reward or aversive cues, a cue activity preference gradually developed only in aversive-preferring axons. We inferred the trial-by-trial cue discrimination based on machine learning using anticipatory licking or facial expressions, and found that successful discrimination was accompanied by sharper selectivity for the aversive cue in aversive-preferring axons. Our findings indicate that a group of mesocortical dopamine axons encodes aversive-related signals, which are modulated by both classical conditioning across days and trial-by-trial discrimination within a day.

Abstract
PURPOSE Studies have shown that surgical site infection (SSI) incidence is lower in patients undergoing laparoscopic surgery. Therefore, we reported the SSI countermeasures adopted by our institution and aimed to evaluate the association between SSI occurrence and postoperative colorectal cancer recurrence and the usefulness of laparoscopic surgery for prognosis. METHODS Among the patients with colorectal cancer who underwent radical surgery at our hospital between January 2015 and December 2017, 197 with stage I-III cancer without distant metastases were included. We retrospectively analyzed patients' electronic medical records and classified them into the non-SSI (without SSI, n = 159) and SSI (with SSI, n = 38) groups. We calculated and compared the 5-year relapse-free survival (RFS) and overall survival (OS) rates. Additionally, we assessed the relationship between prognosis in the non-SSI, incisional SSI, and organ/space SSI groups and the usefulness of laparoscopic surgery. RESULTS The 5-year RFS and OS were 80.5% versus 63.2% (P = 0.024; hazard ratio [HR], 2.065; 95% confidence interval [CI], 1.099-3.883) and 88.7% versus 84.2% (P = 0.443; HR, 1.436; 95% CI, 0.570-3.617), respectively. The SSI group had a significantly worse 5-year RFS prognosis. Regarding the relationship with laparoscopic surgery, the SSI incidence was 45.0% (9/20 cases) and 16.4% (29/177 cases) with laparotomy and laparoscopic surgery, respectively, indicating a significantly reduced SSI occurrence with laparoscopic surgery (P = 0.005). CONCLUSION Patients with SSI were at high risk for colorectal cancer recurrence, and laparoscopic surgery may be useful for reducing SSI.

Abstract
Introduction Hemobilia, which refers to bleeding from the bile duct, is rare and difficult to treat. We report a case of successful hemostasis of a pancreatic tumor complicated by hemobilia. Case Presentation A 76-year-old man was referred to our hospital with a pancreatic head tumor. Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasonography-FNA were performed, and the patient was diagnosed with pancreatic metastasis of renal cell carcinoma. After discharge, the patient noted worsening jaundice and progressive anemia and was readmitted. ERCP reveals active bleeding from the duodenal papillae. The patient was placed on a fully covered metallic stent and discharged after confirming hemostasis. Conclusion Renal cell carcinoma is a tumor with abundant blood flow. If hemobilia occurs, bleeding from pancreatic metastatic tumors should be considered. Additionally, hemostasis using a fully covered metallic stent is useful for treating hemobilia in tumors.

Abstract
The American Joint Committee on Cancer (AJCC) 8th edition T-staging system for distal cholangiocarcinoma (DCC) proposes classification according to the depth of invasion (DOI); nevertheless, DOI measurement is complex and irreproducible. This study focused on the fibromuscular layer and evaluated whether the presence or absence of penetrating fibromuscular invasion of DCC contributes to recurrence and prognosis. In total, 55 patients pathologically diagnosed with DCC who underwent surgical resection from 2002 to 2022 were clinicopathologically examined. Subserosal layer and/or pancreatic (SS/Panc) invasion, defined as penetration of the fibromuscular layer and invasion of the subserosal layer or pancreas by the cancer, was assessed with other clinicopathological prognostic factors to investigate recurrence and prognostic factors. According to the AJCC 8th edition, there were 11 T1, 28 T2, and 16 T3 cases, with 44 (80%) cases of SS/Panc invasion. The DOI was not significantly different for both recurrence and prognostic factors. In the multivariate analysis, only SS/Panc was identified as an independent factor for prognosis (hazard ratio: 16.1; 95% confidence interval: 2.1-118.8, p = 0.006). In conclusion, while the determination of DOI in DCC does not accurately reflect recurrence and prognosis, the presence of SS/Panc invasion may contribute to the T-staging system.

Abstract
BACKGROUND Ruptured aneurysm is a serious complication of distal pancreatectomy (DP) or pancreatoduodenectomy (PD) that can be life-threatening if not treated promptly. This study aimed to examine the efficacy of a Viabahn stent graft for stopping bleeding after pancreatectomy. METHODS Between April 2016 and June 2022, we performed 245 pancreatectomies in our institution. Six patients experienced postoperative bleeding and underwent endovascular treatment. RESULTS All six cases of bleeding occurred post-PD (3.7%). The bleeding was from gastroduodenal artery (GDA) pseudoaneurysms in three patients, and Viabahn stent grafts were inserted. All three patients did not show liver function abnormalities or hepatic blood flow disorders. One patient with a Viabahn stent graft experienced rebleeding, which required further management to obtain hemostasis. Of the six cases in which there was hemorrhage, one case of bleeding from the native hepatic artery could not be managed. CONCLUSIONS Using the Viabahn stent graft is an effective treatment option for postoperative bleeding from GDA pseudoaneurysms following PD. In most cases, using this device resulted in successful hemostasis, without observed abnormalities in hepatic function or blood flow.

Abstract
Aim Nonalcoholic fatty liver disease (NAFLD) can occur due to various reasons after pancreaticoduodenectomy (PD). This study examined the risk and perioperative determinants of NAFLD and fat deposition after PD. Methods A total of 101 patients who had undergone computed tomography 6 months after PD were included. We compared perioperative factors between patients who developed NAFLD and those who developed fatty deposits after PD. Results In the NAFLD group, pancreatic cancer was significantly more prevalent among patients who developed postoperative NAFLD (p = 0.024) and had a lower postoperative body mass index (BMI; p = 0.008). Multivariate analysis revealed that pancreatic carcinoma (hazard ratio [HR] 4.42, 95% confidence interval [CI] 1.118-17.442, p = 0.034) and lower postoperative BMI (HR 0.51, 95% CI 0.274-0.954, p = 0.0355) were risk factors for fatty liver. Pancreatic leakage (p = 0.024) and postoperative BMI (p = 0.002) were significantly lower in the fat deposition group than those in the NAFLD group. Multivariate analysis also revealed that a lower postoperative BMI was a risk factor for fat deposition (HR 0.56, 95% CI 0.523-0.982, p = 0.042). Moreover, multivariate analysis revealed that the fat deposition group had significantly lower pancreatic leakage than the NAFLD group (HR 7.944, 95% CI 1.993-63.562, p = 0.049). Conclusion The findings of this study suggest that postoperative BMI and pancreatic cancer are associated with a higher risk of NAFLD after PD, possibly because of pancreatic exocrine insufficiency and impaired fat absorption.

Abstract
The utility of endoscopic ultrasound fine-needle aspiration cytology (EUS-FNAC) or endoscopic ultrasound fine-needle aspiration biopsy (EUS-FNAB) for diagnosis of small and large pancreatic ductal adenocarcinomas (PDACs) remains in question. We addressed this by analyzing 97 definitively diagnosed cases of PDAC, for which both EUS-FNAC and EUS-FNAB had been performed. We subclassified the 97 solid masses into small (n = 35) or large (n = 62) according to the maximum tumor diameter (<24 mm or ≥24 mm) and compared the diagnostic sensitivity (truly positive rate) of EUS-FNAC and of EUS-FNAB for small and large masses. Diagnostic sensitivity of EUS-FNAC did not differ between large and small masses (79.0% vs. 60.0%; p = 0.0763). However, the diagnostic sensitivity of EUS-FNAB was significantly higher for large masses (85.5% vs. 62.9%; p = 0.0213). Accurate EUS-FNAC-based diagnosis appeared to depend on the degree of cytological atypia of cancer cells, which was not associated with quantity of cancer cells. The accuracy of EUS-FNAB-based diagnosis appeared to depend on cancer cell viability in large masses and cancer volume in small masses. Based on the advantages or disadvantages in each modality, both modalities play an important role in the qualitative diagnosis of PDAC as a complementary procedure.

Abstract
CD133, also called prominin-1, is widely known as a cancer stem cell marker, and its high expression correlates with a poor prognosis in many cancers. CD133 was originally discovered as a plasma membranous protein in stem/progenitor cells. It is now known that Src family kinases phosphorylate the C-terminal of CD133. However, when Src kinase activity is low, CD133 is not phosphorylated by Src and is preferentially downregulated into cells through endocytosis. Endosomal CD133 then associates with HDAC6, thereby recruiting it to the centrosome via dynein motors. Thus, CD133 protein is now known to localize to the centrosome as endosomes as well as to the plasma membrane. More recently, a mechanism to explain the involvement of CD133 endosomes in asymmetric cell division was reported. Here, we would like to introduce the relationship between autophagy regulation and asymmetric cell division mediated by CD133 endosomes.

Abstract
PURPOSE This study compared the pros and cons of two post-distal gastrectomy (DG) reconstruction methods by comparing the patient quality of life and functional dynamics at one year postoperatively. METHODS We compared functional outcomes between Billroth I following laparoscopic 1/2 DG (L-B1; n = 27) and Roux en Y following laparoscopic 4/5 DG (L-RY; n = 24), including laparoscopic total gastrectomy (L-TG; n = 25), at one year postoperatively. Clinical investigations were performed in each patient, and functional evaluations by the acetaminophen (AAP) absorption test and plasma gastrointestinal hormone measurements were performed in consenting patients in each group (L-B1: n = 10, L-RY: n = 10, L-TG: n = 5). RESULTS Postoperative/preoperative body weight ratios were significantly higher in the L-B1 and L-RY groups, in descending order than the L-TG group, although the meal intake ratio was not significantly different between the L-B1 and L-RY groups. The incidence of remnant gastritis was significantly higher in the B1 than in the RY group. AAP levels, glucose and glucagon-like peptide 1 were significantly lower in the L-B1 than in the L-RY group. Active ghrelin levels (AGL) were similar between the L-B1 and L-RY groups. CONCLUSIONS L-B1 maintains gradual intestinal absorption and physiological meal passage and prevents postoperative weight loss. L-RY results in maintenance of the postoperative meal intake via high AGL, equivalent to that in the L-B1 group.

Abstract
BACKGROUND Recent advancements in molecularly targeted chemotherapy for stage IV colorectal cancer have enabled the possibility of complete resection in primary colorectal cancer, which often involves distant liver or lung metastases, by aggressive surgical resection followed by multi-combination chemotherapy. CASE DESCRIPTION A 73-year-old man treated previously for hyperuricemia, hypertension, and a dissecting abdominal aortic aneurysm was referred to us after an incidental finding of multiple liver masses on abdominal ultrasound during follow-up for the aneurysm. A detailed examination by contrast-enhanced computed tomography revealed a ring-enhancing mass larger than 5 cm in diameter in segment 3 of the liver and more than 6 low-density areas with total diameter of 1 to 2 cm in both lobes. A barium enema examination revealed a Borrmann type 2 lesion covering two-thirds of the circumference of the colon, with a 5-cm major axis in the rectosigmoid colon. Biopsy revealed a well-differentiated adenocarcinoma. The patient was diagnosed with stage IV rectal cancer. Because there was no intestinal obstruction, we administered 9 cycles of bevacizumab with capecitabine and oxaliplatin as chemotherapy. Subsequent diagnostic imaging revealed the metastatic lesions in liver segment 3 had reduced to 2 low-density areas with a diameter of 8 mm, and the other hepatic metastases had disappeared; the main tumor had flattened and shrunk. Therefore, we used hand-assisted laparoscopic surgery (HALS) to perform anterior resection of the rectosigmoid colon and partial resection of liver segment 3 as conversion therapy. The patient was discharged 10 days after surgery. The rectal lesion was a well-differentiated adenocarcinoma with a depth of invasion of p-MP and a spread of L0, V0, and pN0. The partial hepatectomy did not indicate viable cancer cells; only necrotic, lysed tissue was observed. Postoperative chemotherapy involved 4 cycles of bevacizumab with capecitabine and oxaliplatin. At more than 42 months postoperatively, no metastasis or recurrence has been observed. CONCLUSIONS This rare case demonstrates that conversion surgery can be a viable option following systemic chemotherapy in patients with advanced colon cancer and H3 liver metastases.

Abstract
BACKGROUND Pancreatic fistula is the most problematic complication in pancreatectomy. Although drainage can be used to relieve this complication, pancreatic surgeons often encounter refractory pancreatic fistula. Fibrin glue injection, with the use of a twofold diluted solution B and a double-lumen tube, was found effective in treating this complicated pancreatic fistula. CASE PRESENTATION We report the case of a 64-year-old Japanese man who underwent laparoscopic distal pancreatectomy for pancreatic tail cancer. After initial drainage of the pancreatic fistula diagnosed 4 days postoperatively, on day 134, refractory pancreatic fistula was observed using contrast-enhanced computed tomography. We used fibrin glue injection, with a twofold diluted solution containing thrombin and calcium chloride and a double-lumen tube, for treating the refractory fistula; the fluid drainage was almost stopped with no fever or abdominal pain. No recurrence of pancreatic cancer has been observed since the procedure. CONCLUSIONS Fibrin glue injection was effective for complicated pancreatic fistula after distal pancreatectomy. Using a twofold diluted solution B containing thrombin and calcium chloride and a double-lumen tube makes possible the thorough injection of fibrin glue.

Abstract
Background Neoadjuvant chemotherapy (NAC) has been conducted for patients with non-resectable colorectal cancer; however, few reports of a systematic approach to NAC exist. At our hospital, bevacizumab with capecitabine and oxaliplatin (B-mab XELOX) has been used as chemotherapy for Stage IV colorectal cancer since 2014. We aimed to evaluate the efficacy and safety of NAC with a molecular-targeting agent for Stage IV colorectal cancer. Methods A retrospective, single-institute analysis was performed including 27 patients with advanced recurrent cancer following primary tumor resection and 43 patients with non-resectable tumors and remote metastasis. At the time of resection, 17 were receiving chemotherapy. All 70 patients received at least 3 cycles of B-mab XELOX (total: 920 cycles). We determined the 1-year progression-free survival (1Y-PFS), 1-year overall survival (1Y-OS), 3Y-PFS, 3Y-OS, and number of treatment cycles. The objective response rate, clinical benefit rate, and adverse events were assessed. The number of chemotherapy cycles, survival time, and R0 surgery rate were determined for patients who underwent RO conversion surgery. Results The 1Y-PFS was 28.5% [median survival time (MST): 7.4 months], 1Y-OS was 76.6% (MST not reached), 3Y-PFS was 5.5% (MST: 7.4 months), and 3Y-OS was 26.4% (MST: 25.2 months). The mean and median number of cycles of B-mab XELOX was 13.1 and 10.5, respectively. The objective response rate was 28.6%, and the clinical benefit rate was 58.6%. Grade 1 or Grade 2 adverse events occurred in 60 patients (85.7%); however, they all resolved without intervention. A single Grade 4 event (perforation of the primary tumor) occurred in 1 patient (1.4%). RO conversion surgery was performed in 7 patients (10.0%; primary + liver in 2 patients, primary + lung in 1 patient, liver in 3 patients, and primary in 1 patient). These patients received 3 to 10 cycles preoperatively (mean: 7.3; median: 6.5). R0 surgery was achieved in 5 of the 7 patients (71.4%). Postoperative survival ranged from 1 to 26 months (MST: 8 months). Conclusions This modified regimen was safe and effective in Japanese patients, and a high quality of life/quality-adjusted life-year was achieved. To further evaluate PFS and OS, more patients are being investigated.

Abstract
Background Recently, due to increasing reports of stenosis after esophagojejunostomy created using circular staplers and a transorally inserted anvil (OrVil™) following laparoscopic proximal gastrectomy (LPG) and total gastrectomy (LTG), linear staplers are being used instead. We investigated our preventive procedure for esophagojejunostomy stenosis following use of circular staplers. Methods Since the anastomotic stenosis is considered to be mainly caused by tension in the esophageal and jejunal stumps at the anastomotic site, we have been performing procedures to relieve this tension, by cutting off the rubber band and pushing the shaft of the circular stapler toward the esophageal side, since July 2015. We retrospectively compared the incidence of anastomotic stenosis in cases of LPG and LTG performed before July 2015 (early phase, 30 cases) versus those performed after this period (later phase, 22 cases). Results Comparison of the incidence of anastomotic stenosis according to the type of surgery, LPG or LTG, and between the two time periods versus all cases, indicated a significantly lower incidence in the later phase than in the early phase (4.5 vs. 26.7%, p < 0.05), especially for LPG (0 vs. 38.5%, p < 0.05). Conclusions It is possible to use a circular stapler during laparoscopic esophagojejunostomy, as with open surgery, if steps to reduce tension on the anastomotic site are undertaken. These procedures will contribute to the spread of safe and simple laparoscopic anastomotic techniques.

Abstract
BACKGROUND Sclerosing angiomatoid nodular transformation (SANT) of the spleen is a non-tumorous benign lesion that originates in the spleen and It is rare. CASE PRESENTATION A 59-year-old man visited his physician for a checkup. Ultrasonography showed a mass in the spleen, and the patient was referred to our hospital. He tested negative for tumor markers and soluble interleukin-2 receptor (sIL-2R). Abdominal computed tomography revealed a 51-mm hypovascular mass that was slowly enhanced from the portal venous to the equilibrium phases, at the inferior extremity of the spleen. Abdominal magnetic resonance imaging showed a spoke-wheel pattern. Fluorodeoxyglucose positron emission tomography indicated a mild tumor accumulation, with a standardized uptake value max of 5.3. These results led to the suspicion of SANT, angioma, and angiosarcoma. Because the onset of malignant diseases could not be excluded, laparoscopic splenectomy was performed. A brown, round mass, without a capsule but with clear boundaries, was macroscopically observed on the cut surface. In addition, white fibrosis was found in the mass. Histopathological examination revealed nodular angioma lesions, and the proliferation of fibrotic interstices and inflammatory cells was observed between the lesions. Immunohistological examination revealed proliferation in the 3 types of narrow capillaries inside angiomatoid nodules;CD31+/CD34+/CD8-, CD31+/CD34-/CD8+, and CD31+/CD34-/CD8- cells; therefore, the patient was diagnosed with SANT. CONCLUSIONS Here, we reported one patient who developed the typical symptoms of SANT. SANT is easily diagnosed by histopathological examination; however, its causes remain unknown. More cases with SANT are required for further analysis.

Abstract
The occurrence of cryptic species within a threatened taxon is rare, but where they do occur, understanding species boundaries is essential for planning an effective conservation strategy. The short-tailed albatross Phoebastria albatrus is a Vulnerable seabird that mainly breeds on Torishima and the Senkaku Islands in the western North Pacific. Although it has been tacitly regarded as a single management unit with 2 breeding sites, the species is known to comprise 2 genetically separated populations (Senkaku-type and Torishima-type). However, morphological examination of birds from both populations has not been conducted owing to the difficulty in accessing the Senkaku Islands. In this study, we examined the morphological differences between immigrants from the Senkaku Islands to Torishima (Senkaku-type) and native birds on Torishima (Torishima-type) and found significant differences in morphological characteristics between the 2 bird types. In general, Torishima-type birds were larger than Senkaku-type birds, whereas Senkaku-type birds had relatively longer beaks. Based on the morphological differences found in this study as well as genetic and ecological differences revealed in previous studies, we believe that Senkaku- and Torishima-type birds should be classified as different cryptic species. To the best of our knowledge, this is the first case of cryptic species being identified in a threatened avian species.

Abstract
Asymmetric cell division (ACD) is an important physiological event in the development of various organisms and maintenance of tissue homeostasis. ACD produces two different cells in a single cell division: a stem/progenitor cell and differentiated cell. Although the balance between self-renewal and differentiation is precisely controlled, disruptions to ACD and/or enhancements in the self-renewal division (symmetric cell division: SCD) of stem cells resulted in the formation of tumors in Drosophila neuroblasts. ACD is now regarded as one of the characteristics of human cancer stem cells, and is a driving force for cancer cell heterogeneity. We recently reported that MYCN controls the balance between SCD and ACD in human neuroblastoma cells. In this mini-review, we discuss the mechanisms underlying MYCN-mediated cell division fate.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy (NACRT) has not been accepted as a general therapy for gastric cancer because of its localized effect and toxicity for radiosensitive organs. However, if radiation therapy could compensate for the limited or inadequate treatment choices available for elderly patients and/or those at high risk, the available therapeutic options for advanced gastric cancer might increase. From this perspective, we present our experiences of five patients with advanced gastric cancer in whom we used NACRT therapy with interesting results. CASE SUMMARY We admitted five patients with clinical Stage III gastric cancer and bulky lymph node metastasis or adjacent organ invasion at the time of diagnosis. A total of 50 Gy of preoperative intensity modulated radiation therapy was delivered to the patients in doses of 2.0 Gy/d, together with a regimen of concomitant chemotherapy comprising two courses of oral tegafur/gimeracil/oteracil (S-1; 65 mg/m2 per day) for three consecutive weeks followed by two weeks of rest, starting at the same time as radiotherapy. All patients underwent no residual tumor resection and a pathological complete response of the primary tumors was achieved in two patients. The incidence of hematological toxicity was low, although the digestive toxicities of anorexia and diarrhea developed in three of the five patients, necessitating termination of radiation therapy at 30 Gy and S-1 at three weeks. However, even 30 Gy of irradiation and half the dose of S-1 resulted in sufficient downstaging, indicating that even a reduced amount of NACRT could confer considerable effects. CONCLUSION Slightly reduced NACRT might be useful and safe for patients with locally advanced gastric cancer.

Abstract
The patient was a 72-year-old man who consulted with his previous physician for chief complaints of palpitations, fatigue, and blackish feces persisting for 1 month. After confirming the presence of anemia, the patient was referred to our hospital. Blood test findings upon hospital arrival revealed a hemoglobin (Hb) level of 6.0 g/dL. Computed tomography revealed a tumor of 32 mm × 30 mm with a low-density area extending from the bulb to the second part of the duodenum. Magnetic resonance imaging revealed high signal intensity on T1- and T2-weighted imaging and low signal intensity on fat-suppressed T2-weighted imaging, findings consistent with lipoma. Upper gastrointestinal endoscopy revealed a yellowish submucosal tumor that had perforated into the intestinal tract from the external wall extending from the upper corner to the second part of the duodenum. After determining that the tumor was sessile, laparoscopic partial duodenectomy with Roux-en-Y reconstruction was planned and performed. Pathology revealed a yellowish tumor 4 cm × 4 cm in size extending from the pyloric area to the duodenal bulb arising from the tunica muscularis. The present case report details our experience involving a patient who underwent surgical resection for hemorrhagic duodenal lipoma.

Abstract
OBJECTIVE This study of 45 patients aimed to retrospectively examine whether the relationships among the postoperative to preoperative body weight ratio (BWR), meal intake as a good indicator of quality of l ife (QOL), and absorptive kinetics from the small intestine could be expressed by the acetaminophen (AAP) concentration. METHODS The postoperative/preoperative BWR and meal intake ratio (MIR) were evaluated in 30 patients who underwent open distal gastrectomy for advanced gastric cancer (ODG group) and 15 patients who underwent laparoscopic proximal gastrectomy for early gastric cancer (LPG group). In addition, all patients underwent functional evaluation using the AAP method. Correlation coefficients of the BWR and MIR with the plasma AAP concentration after meal intake were evaluated. RESULTS There was a negative correlation between the AAP concentration at 15 min and the BWR in all patients (r = -0.438, P = 0.00259, n = 45) and a weak negative correlation between the AAP concentration at 15 min and the MIR (r = -0.309, P = 0.0368, n = 45). CONCLUSIONS There were some relationships between slow intestinal absorption in the early postprandial phase and the maintenance of postoperative body weight and meal intake. Namely, operative methods that maintained preoperative slow intestinal absorption were thought to be better for maintaining postoperative QOL.

Abstract
Glioblastoma (GBM) is a malignant tumor with a high recurrence rate and has very poor prognosis in humans. The median survival is still <2 years. Therefore, a new treatment strategy should be established. Recently, this cancer has been thought to be heterogeneous, consisting of cancer stem cells (CSCs) that are self-renewable, multipotent, and treatment resistant. So various strategies targeting glioma stem-like cells (GSCs) have been investigated. This study focused on strategies targeting GSCs through the induction of differentiation using bone morphogenetic protein 4 (BMP4). The expression of CD133, a cancer stem cell marker, under BMP4 treatment in GSCs was examined using flow cytometry, western blotting, and quantitative PCR. Immunofluorescent staining of GSCs was also performed to examine the type of cell division: asymmetric cell division (ACD) or symmetric cell division (SCD). We obtained the following results. The BMP4 treatment caused downregulation of CD133 expression. Moreover, it induced ACD in GSCs. While the ACD ratio was 23% without BMP4 treatment, it was 38% with BMP4 treatment (P=0.004). Furthermore, the tumor sphere assay demonstrated that BMP4 suppresses self-renewal ability. In conclusion, these findings may provide a new perspective on how BMP4 treatment reduces the tumorigenicity of GSCs.

Abstract
A 67-year-old woman presented with a chief complaint of umbilical region mass and epigastric pain. Carbohydrate antigen 19-9 (CA19-9) level was 177.5 U/mL; computed tomography (CT) showed a hypovascular mass lesion of 20 mm × 20 mm in the pancreas, infiltration into the superior mesenteric artery and dilation of the main pancreatic duct. Peritoneal dissemination to the omentum and abdominal wall was observed. The patient was diagnosed with T4N0M1, cStage IV unresectable pancreatic body cancer and was started on GEM + nab-PTX therapy. She underwent chemotherapy for 10 months for a total of 10 cycles. The CA19-9 level returned to normal, CT showed reduction in tumor size to 11 mm × 8 mm, and peritoneal dissemination also disappeared. Disappearance of peritoneal dissemination was also observed on Positron emission tomography (PET). Laparoscopic surgery was planned, and rapid pathological examination results of ascites washing cytology and peritoneal mass were negative. Laparoscopic distal pancreatectomy was then performed, which transitioned to hand-assisted laparoscopic surgery; R0 resection was achieved. The patient underwent outpatient postoperative adjuvant chemotherapy with orally administered S-1 and has been recurrence-free for 1 year postoperatively. This case demonstrates that patients with pancreatic body cancer with distant metastasis can undergo R0 resection following GEM + nab-PTX combination therapy.

Abstract
Background Synchronous and asynchronous multiple cancers have become more pervasive in recent years despite advances in medical technologies. However, there have been only six cases (including the present case) that underwent pancreaticoduodenectomy (PD) for pancreas head cancer following surgery for esophageal cancer. PD for treating pancreas head cancer is extremely challenging; thus, the confirmation of vessel variation and selection of surgical procedures are vital. Case presentation The patient was a 78-year-old Japanese male who was synchronously diagnosed with esophageal and cecal cancer 7 years previously at our hospital. He was admitted with densely stained and jaundiced urine and presented no remarkable family medical history. Following various examinations, surgery was performed due to the diagnosis of distal cholangiocarcinoma (pancreatic head cancer). Since the tumor was located far from the gastroduodenal artery (GDA) and no significant lymph node metastases could be found, subtotal stomach-preserving PD was performed instead of the resection of GDA with the right gastroepiploic artery (RGEA) for gastric tube blood flow preservation. The common hepatic artery (CHA) and GDA were confirmed, and RGEA diverged from GDA was identified. Subsequently, their respective tapings were preserved. The right gastric artery (RGA) was identified, taped, and preserved considering the gastric tube blood flow. The inflow area of the right gastroepiploic vein (RGEV) through gastric colic vein trunk in the superior mesenteric vein was exposed and preserved as the outflow of gastric tube blood flow. PD was completed without any complications on the shade of the gastric tube. Conclusions This case report describes successfully preserved gastric blood flow without the resection of GDA, RGEA, RGEV, or RGA. To preserve the gastric tube, GDA inflow, RGEA, RGA, and RGEV outflow should be preserved if possible. When performing PD after tube reconstruction, it is essential to confirm the relative positions of the blood vessel, blood flow, and tumor through three-dimensional computed tomography angiography before surgery and to consider the balance between the invasiveness and optimal curability of the surgery.

Glioblastoma (GBM) is one of the human malignant tumors with a high recurrence rate and the poorest prognosis. Therefore, a new treatment strategy is required. It has also come to be thought that cancer is a heterogeneous, which composes of cancer stem cells (CSCs), which have self-renewal ability, multipotency and treatment resistance. Although various strategies targeting glioma stem-like cells (GSCs) have been studied, a median survival remains to be less than 2 years. In this study, we focused on strategies targeting GSCs through induction of differentiation using BMP4. We examined the expression of CD133, a cancer stem cell marker, under BMP4-treatment in GSCs using flowcytometry analysis, western blotting and qPCR. We also examined immunofluorescent staining of GSCs to study cell division. The treatment of BMP4 caused downregulation of CD133 expression in GSCs. In addition, BMP4-treatment induced to asymmetric cell division in GSCs. Tumor sphere assay showed that BMP4 suppresses self-renewal ability. These findings may provide a new perspective how BMP4 reduces the tumorigenicity of GSCs.

Abstract
Background Gastric duplication is a relatively rare congenital malformation, accounting for approximately 2.9–3.8% of gastrointestinal duplications. Gastric duplication cyst is a congenital anomaly that is rarely observed in adults. Accurate diagnosis of these cysts before resection is difficult. In this report, we describe a patient with gastric duplication cysts that were treated by laparoscopic resection. Case presentation A 46-year-old Japanese woman was referred to our institution because a cystic lesion in the pancreatic tail was detected by ultrasonography during a health examination. The lesion had a clearly defined boundary of approximately 40 mm. A thick cystic lesion of the septum was observed in the pancreatic tail, but invasion into the stomach wall was not recognized on a computed tomographic scan. Endoscopic ultrasonography revealed that the tumor appeared smooth with a marginal edge, which was characterized by echo with high homogeneity, and the presence of viscous mucus was suspected. The preoperative diagnosis of mucinous cystic neoplasm was the reason for laparoscopic tumor resection. The resected specimen was a smooth surface tumor, and it was full of mucus. Histopathological study revealed that the mucosa was covered with crypt epithelium, muscularis mucosae, intrinsic muscularis, and serosa, and the wall of the tumor had a structure very similar to that of the stomach wall. The mucosa was partially drained by intrinsic gastric glands, but most of them were denucleated. No pancreatic tissue was present, and the tumor had no continuity with the spleen. These findings indicated a diagnosis of gastric duplication cyst with no continuity with the stomach wall. Conclusions In our experience, it is difficult to differentiate gastric duplication cyst from mucinous cystic neoplasm before laparoscopic resection. Events such as infection, bleeding, perforation, ulceration, fistula formation, obstruction, and compression have been linked to gastric duplication cysts, and malignant transformation of these cysts has been reported. Therefore, we suggest that resection should be the first treatment option for gastric duplication cysts.

Abstract
This is a case of a 75-year-old man who was diagnosed with anaplastic pancreatic ductal carcinoma (spindle cell type). His image findings showed pancreatic head cysts and pancreatic head, body, and tail tumors respectively. EUS-FNA was performed to the pancreatic head and pancreatic body tumors, and the same high atypical type cells suspected of cancer were obtained from either specimen, and finally total pancreatectomy was performed. On the specimen, there were 4 lesions in the pancreas; histology showed that the same anaplastic pancreatic ductal carcinoma (spindle cell type) was obtained from the pancreatic head cyst and the pancreatic tumors.

Abstract
CD133 is a transmembranous protein that mainly localises to the plasma membrane in haematopoietic and neural stem cells as well as cancer stem cells. Although CD133 also localises to the cytoplasm, the mechanism of action and function of cytoplasmic CD133 currently remain unknown. We herein demonstrated that when Src family kinase activity is weak, CD133 interacts with HDAC6 and is transported to the pericentrosomal region after internalization and endosome formation via the dynein-based traffic system. Pericentrosomal CD133 is then recycled to the plasma membrane via recycling endosomes. At the pericentrosomal region, endosomal CD133 captures GABARAP, an initiator of autophagy, and inhibits GABARAP-mediated ULK1 activation and the subsequent initiation of autophagy. Furthermore, pericentrosomal CD133 suppresses cell differentiation, such as primary cilium formation and neurite outgrowth, by inhibiting autophagy. Thus, the present results provide evidence to suggest that pericentrosomal CD133 has the unique property of maintaining the undifferentiated status of cells by inhibiting autophagy.

Abstract
We report a case of high-grade pancreatic intraepithelial neoplasia (PanIN) concomitant with lymphoplasmacytic sclerosing pancreatitis. The patient was an 82-year-old man in whom narrowing of the main pancreatic duct was detected incidentally by abdominal ultrasonography. Magnetic resonance cholangiopancreatography further revealed abrupt narrowing plus distal dilatation of the duct, from the pancreatic body to the tail. Distal pancreatectomy was performed under a preoperative diagnosis of intraductal papillary-mucinous neoplasm. Macroscopic examination of the surgical specimen showed an ill-demarcated, white-gray area and prominent pancreatic atrophy, while histological analysis detected small (<5 mm in diameter) cystic dilatations of the main pancreatic duct and some branch ducts plus pancreatic atrophy with fibrosis and fatty replacement of acinar cells. We also detected variously sized papillary projections, fused glands, and scattered focal papillary proliferation of columnar ductal epithelium comprising cells with elongated, mildly hyperchromatic nuclei, consistent with high-grade PanIN. In addition, we observed marked lymphoplasmacytic infiltration, periductal storiform fibrosis, and obliterative phlebitis. Immunohistochemical staining revealed abundant immunogloblin G4-positive plasma cells, indicative of type 1 autoimmune pancreatitis (AIP). The coexistence of high-grade PanIN and marked lymphoplasmacytic infiltration, typical of AIP, point to a close association between the former, as a carcinogenic process, and the latter, as an immune response.

Abstract
We previously identified a gain-of-function mutation in PPP3CB in a neuroblastoma (NB) with MYCN amplification. Here we investigated the functional and clinical role of PPP3CB in NB. High PPP3CB expression was an independent indicator predicting poor prognosis of NB. Overexpression of wildtype or mutated PPP3CB (PPP3CBmut) promoted cell growth, but PPP3CB knockdown decreased cell growth in NB cells. Forced expressions of PPP3CB and PPP3CBmut activated NFAT2 and NFAT4 transcription factors and inhibited GSK3β activity, resulting in the increase in the expressions of c-Myc, MYCN, and β-catenin, which were downregulated in response to PPP3CB knockdown. Treatment with calcineurin inhibitor cyclosporin A (CsA) or FK506 suppressed cell proliferation and induced apoptotic cell death in both MYCN-amplified and MYCN-non-amplified NB cell lines. Expression of PPP3CB protein was decreased in response to two calcineurin inhibitors. c-Myc, MYCN, and β-catenin were downregulated at the mRNA and protein levels in CsA or FK506-treated NB cells. Our data indicate that elevated expression of PPP3CB and the expression of its constitutively active mutant contribute to the aggressive behavior of NB tumors and therefore suggest that inhibition of calcineurin activity might have therapeutic potential for high-risk NB.

Abstract
INTRODUCTION Gastrointestinal neuroendocrine tumors (GI-NETs) often show hematogenous metastasis, with the liver being the most common metastatic site; however, metastasis to the pancreas is rare. CASE PRESENTATION We report a rare case of rectal NETs with pancreatic metastases in a 75-year-old man who presented with a chief complaint of constipation. Imaging and endoscopic findings revealed a rectal submucosal tumor, a pancreatic hypovascular mass, and multiple liver masses. The rectal lesion and pancreatic lesions were diagnosed as neuroendocrine tumors using biopsy and endoscopic ultrasound fine-needle aspiration, respectively. Synchronous rectal NET and pancreatic NET (P-NET) with liver metastasis of either of these two were preoperatively diagnosed. A two-stage surgery was performed, comprising abdominoperineal resection and distal pancreatectomy. Pre-operative imaging findings showed a solitary mass in the pancreas, although the resected specimen contained multiple lesions. Immunohistochemical staining of the resected rectal and pancreatic lesions showed that both were synaptophysin positive and chromogranin A (CgA) negative. Generally, rectal NET cells are positive for synaptophysin and negative for CgA, while the majority of P-NETs are positive for both. The final diagnosis was rectal NETs with pancreatic and liver metastases. Till date, there have been no reports on the outcomes in patients with pancreatic metastasis of GI-NETs. CONCLUSIONS More case reports on metastatic NETs are needed to arrive at a consensus for a standardized treatment regimen.

Abstract
Background Biliary system anatomical abnormalities can be preoperatively detected on magnetic resonance imaging; therefore, some presume that the number of bile duct injuries should decline. However, once a bile duct injury occurs, repair may be difficult. There are various ways to repair bile duct injuries, but successful repair may be exceptionally difficult. Case presentation A 72-year-old Japanese man underwent a pancreaticoduodenectomy due to a diagnosis of middle bile duct cancer. We had a complication of an isolated posterior segmental biliary obstruction when pancreaticoduodenectomy was performed. We conducted a drip infusion cholecystocholangiography-computed tomography test to determine the positional relationship between his bile duct and elevated jejunum. To secure the bile duct we punctured the bile duct under computed tomography guidance, and the hepaticojejunal anastomosis site was visualized by inserting an endoscope. We vibrated the bile duct wall by inserting a guide wire through a puncture needle and verified the vibrations with the endoscope. We observed a partially compressed elevated jejunal wall upon guide wire insertion; therefore, we could verify a puncture needle penetration into the elevated jejunum by endoscope on insertion. We also successfully inserted an 8.5-Fr pigtail catheter into the elevated jejunum. We removed all drains after percutaneously inserting an uncovered metallic stent. Our patient’s subsequent clinical course was unremarkable. He visits our institution as an out-patient and has had no stent occlusion even after 6 months. Conclusions When repairing bile duct injuries, it is important to accurately determine the positional relationships between the injured bile duct and the surrounding organs.

Abstract
Neuroblastoma is one of the most common solid tumors in children and has a diverse clinical behavior that largely depends on the tumor biology. Neuroblastoma exhibits unique features, such as early age of onset, high frequency of metastatic disease at diagnosis in patients over 1 year of age and the tendency for spontaneous regression of tumors in infants. The high-risk tumors frequently have amplification of the MYCN oncogene as well as segmental chromosome alterations with poor survival. Recent advanced genomic sequencing technology has revealed that mutation of ALK, which is present in ~10% of primary tumors, often causes familial neuroblastoma with germline mutation. However, the frequency of gene mutations is relatively small and other aberrations, such as epigenetic abnormalities, have also been proposed. The risk-stratified therapy was introduced by the Japan Neuroblastoma Study Group (JNBSG), which is now moving to the Neuroblastoma Committee of Japan Children's Cancer Group (JCCG). Several clinical studies have facilitated the reduction of therapy for children with low-risk neuroblastoma disease and the significant improvement of cure rates for patients with intermediate-risk as well as high-risk disease. Therapy for patients with high-risk disease includes intensive induction chemotherapy and myeloablative chemotherapy, followed by the treatment of minimal residual disease using differentiation therapy and immunotherapy. The JCCG aims for better cures and long-term quality of life for children with cancer by facilitating new approaches targeting novel driver proteins, genetic pathways and the tumor microenvironment.

Abstract
PURPOSE Nectin-1 is a cell adhesion molecule that regulates the formation of adherens junctions and tight junctions. We measured the expression of nectin-1 in cancer-associated fibroblasts (CAFs) in patients with pancreatic ductal adenocarcinoma (PDAC). METHODS Nectin-1 expression was measured via immunohistochemistry using tissue microarray blocks constructed from resected PDAC tissue from 258 patients. We screened for associations between nectin-1 expression and clinicopathological parameters. According to the percentage of CAFs stained, expression was classified as negative at ≤ 30% and positive at > 30%. RESULTS Nectin-1 expression was confirmed in CAFs from 64 patients (24.8%), and was associated with lymph node metastasis (p = 0.016), advanced Union for International Cancer Control stage (p = 0.016), perineural invasion (p = 0.022), pancreatic head tumors (p = 0.023), and shorter overall survival (p = 0.003). Multivariate analysis revealed that nectin-1 expression in CAFs was an independent prognostic factor (p = 0.038). CONCLUSIONS Diffuse nectin-1 expression in the CAFs of PDAC patients is associated with invasion, metastasis, and shorter survival.

Abstract
We present two cases of intestinal obstruction due to intersigmoid hernia that were diagnosed and treated laparoscopically. The first case was a 42-year-old woman with no surgical history. She was treated conservatively with the insertion of an ileus tube. Although the intestinal obstruction improved temporarily, since it subsequently worsened, laparoscopic surgery was performed, which revealed incarceration of the ileum in the intersigmoid fossa. Although there were no signs of necrosis after intestinal release, partial resection of the small bowel was performed before the hernial orifice was closed due to the evidence of serous damage. The second case was a 53-year-old man with no surgical history. An ileus tube was inserted for intestinal decompression, following which laparoscopic surgery was performed. Operative findings revealed incarceration of the ileum in the intersigmoid fossa, and, since there were no signs of necrosis after intestinal release, the hernial orifice was closed without performing intestinal resection. This condition is a good indication for laparoscopic surgery, given that intestinal necrosis is frequently absent and the operation can usually be completed simply by release of the incarcerated intestine and closure of the hernia orifice. Intersigmoid hernia should be suspected in cases of intestinal obstruction with no surgical history.

Abstract
The biological behavior of a cystic pancreatic endocrine neoplasm is less aggressive than that of pancreatic neuroendocrine neoplasms, and its prognosis is better. Limited surgery should be considered for cystic pancreatic endocrine neoplasms that are not accompanied preoperatively by lymph node or distant metastasis.

Abstract
Undifferentiated carcinoma of the ampulla of Vater is a rare disease with unclear and clinical characteristics and prognosis. Here, we report the case of a 61-year-old man with undifferentiated carcinoma of the ampulla of Vater. He presented to our hospital with an increase in hepatobiliary system enzymes that was detected during a health check-up. Imaging and endoscopy demonstrated a tumor with ulcer in the ampulla of Vater, which was diagnosed as a carcinoma by biopsy. No distant metastasis was observed. Subtotal stomach-preserving pancreaticoduodenectomy was performed. Undifferentiated carcinoma was confirmed based on the presence of small round atypical cells with the formation of a solid alveolar lesion on histopathological examination and immunohistochemical staining that was positive for CAM 5.2 but negative for chromogranin A and synaptophysin. The tumor infiltrated the duodenum, but not the pancreas; no lymph node metastasis was observed. However, liver metastases were detected 2 months postoperatively. Chemotherapy was performed, and the tumor size temporality decreased; however, it grew in size again, and the patients subsequently died of the primary disease 15 months postoperatively. Undifferentiated carcinoma of the ampulla of Vater is a very rare histological type. More number of cases is necessary to clarify optimal treatment.

Abstract
Background Carcinosarcoma of the ampulla of Vater is extremely rare, and to the best of our knowledge, this is the third reported study. Case presentation The patient was a 73-year-old man, who presented with a chief complaint of dark urine. After a work-up, we suspected duodenal papillary cancer and performed a subtotal stomach-preserving pancreaticoduodenectomy with lymph node dissection. Immunohistochemically, the sarcomatous atypical cells were diffusely positive for cytokeratin AE1&3 and vimentin and focally positive for α-smooth muscle actin; these cells were also negative for desmin, CD34, DOG1, c-kit, and S100. From these findings, we diagnosed the patient with so-called carcinosarcoma. There was no lymph node metastasis. Conclusions Carcinosarcoma of the ampulla of Vater has a poor prognosis, and lymph node metastases are often seen. For the complete cure of carcinosarcoma of the ampulla of Vater, resection with the dissection of the lymph nodes may be necessary.

Abstract
The patient was a 59-year-old female. A liver tumor measuring 10 cm was found in the right hepatic lobe by medical examination of August, 2008 and she underwent extended right hepatectomy in September. Microscopically, the tumor was composed of small cuboidal cells possessing oval nuclei and resembling cholangiole. These formed small tubular structures with fibrous stroma. From a result of histopathological features, a diagnosis of a cholangiolocellular carcinoma was made. She received postoperative adjuvant chemotherapy with gemcitabine and S-1. After that, the patient underwent six partial hepatectomies by August, 2013 for recurrent intrahepatic cholangiolocellular carcinoma. The patient is doing well 7 years after the first hepatectomy. Cholangiolocellular carcinoma is a rare tumor accounting for less than 1% of primary liver cancer, and the clinicopathologic features are not fully understood. Aggressive surgical resection may be one of the choices to assure a good outcome.
