Abstract
CGK733 was reported as a compound that inhibited ATM/ATR kinase activities and blocked their checkpoint signaling pathways with great selectivity. However, this paper was subsequently retracted, and the truth about the activity of CGK733 remains unclear. We synthesized various analogs of CGK733 with a modification of the carboxylic acid moiety and/or the aniline derivative moiety to accumulate knowledge of the structure-activity relationship of this compound. Growth inhibitory activity of CGK733 and novel 35 analogs against HeLa S3 cells was evaluated, and the structure-activity relationship revealed that analogs with 2-naphthyl or 4-fluorophenyl group instead of the benzhydryl group have activity comparable to CGK733 and that the 3-nitro group on the aniline moiety significantly affects the activity.

Abstract
PURPOSE Distant metastasis develops in approximately one-third of patients with colorectal cancer (CRC) who undergo radical surgery, and colorectal liver metastasis (CRLM) is the most common form of distant metastasis in CRC. Hepatectomy is the only potentially curative treatment for CRLM, but few patients with metastatic CRC meet the criteria for this radical resection, and the 5-year survival rate is poor. Identifying risk factors for CRLM is critical. Non-alcoholic fatty liver disease (NAFLD) is an independent risk factor for CRC. However, the effect of NAFLD on CRC liver metastasis after radical surgery remains unclear. Therefore, we examined the impact of NAFLD-associated hepatic fibrosis on liver metastasis after radical surgery for CRC. METHODS We retrospectively analyzed data from 388 patients who underwent curative surgery for CRC at our hospital between April 2008 and March 2015. The patients' clinical results, surgical procedures, postoperative course, and pathological and survival data were collected from the hospital records. The NAFLD fibrosis score was calculated and used to divide the patients into two groups (NAFLD and non-NAFLD). RESULTS Recurrence was observed in 83/388 (21.4%) patients after a mean follow-up of 65.6 ± 15.1 months. Twenty-five patients had liver metastasis: 8 in the NAFLD group (8/45; 17.8%) and 17 in the non-NALFD group (17/343; 5.0%) (p = 0.004). Liver metastasis-free survival was significantly worse in the NAFLD than non-NAFLD group (p < 0.001). NAFLD and cancer stage were independent risk factors for liver metastasis recurrence. CONCLUSION NAFLD may be a risk factor for liver metastasis in patients with CRC who undergo curative surgery.

Abstract
A gastric inlet patch (GIP) is an ectopic gastric mucosal lesion usually arising at the cervical esophagus that may rarely cause esophageal adenocarcinoma (EAC). To the best of our knowledge, this is the first case of a GIP-derived EAC that was successfully treated using a multidisciplinary treatment approach. A 64-year-old man was referred to the Department of Gastrointestinal Surgery, Kanazawa University Hospital (Kanazawa, Japan) for surgical treatment of refractory recurrent cervical EAC derived from GIP who had previously been treated with induction chemotherapy, definitive chemoradiotherapy and photodynamic therapy (PDT). Esophagogastroduodenoscopy revealed a stenotic tumor at the GIP site in the cervical esophagus and submucosal tumors with suspected multiple intramural metastases in the anal side of the thoracic esophagus. The patient underwent robot-assisted thoracoscopic esophagectomy with laryngopharyngectomy and cervical lymphadenectomy as radical salvage surgery 4 months after the last PDT procedure. After postoperative adjuvant chemotherapy using oral administration of tegafur/gimeracil/oteracil (oral 5-fluorouracil prodrug) for 1 year; at present, the patient is alive without recurrence 3 years after the operation.

Abstract
Segmental gastrectomy, mini-distal gastrectomy and local resection of the stomach are function-preserving curative gastrectomies (FPGs), which are used to treat gastric cancer in specialized centers. These surgical options are less invasive and can alleviate postgastrectomy symptoms more than standard gastrectomy; however, their association with prognosis remains to be fully elucidated. The present study aimed to compare the survival prognosis of patients diagnosed as node-negative by sentinel node biopsy (SNB) treated via FPG with reduced lymph node dissection with that of patients who underwent guideline gastrectomy (GL). This retrospective study was conducted between April 1999 and March 2016. The inclusion criteria were a diagnosis of gastric cancer type 0, of ≤5 cm, located in L or M areas, and pT1N0. Patients who underwent distal gastrectomy and pylorus-preserving gastrectomy were included as controls in the GL group. Among the 146 and 300 patients in the FPG and GL groups, respectively, only 1 patient in the GL group experienced recurrence. The overall survival (OS) of the FPG group was 96.6% at 5 years and 92.5% at 10 years, which was significantly higher than that of the GL group (P<0.05). In addition, the cumulative incidence of non-cancer-related deaths, especially pulmonary diseases, was lower in the FPG group than that in the GL group (P<0.05). Notably, the OS and non-cancer death rate in the FPG group remained significantly better after propensity score-matching analysis. In conclusion, for early gastric cancer located in M or L areas, patients treated via FPG guided by SNB have a better prognosis and fewer deaths caused by respiratory disease than those treated via GL. The present clinical trial was registered under the following trial registration numbers: UMIN000010154 (2013/3/4), UMIN000023828 (2016/8/29), jRCTs041180006 (2018/10/9).

Abstract
INTRODUCTION This study aimed to evaluate the prognostic factors in T4b gastric cancer (GC) in order to improve future therapeutic strategies. METHODS We retrospectively analyzed the medical records of 43 patients with advanced GC who underwent surgery and were surgically or pathologically diagnosed with T4b GC. The overall survival (OS) rate of patients with T4b GC was analyzed, and univariate and multivariate analyses were performed to identify clinicopathological factors that were independently associated with OS. In addition, we assessed the relationship between postoperative chemotherapy and laboratory parameters 4 weeks post-surgery. RESULTS The proportion of patients with invasion of cancer in organs, including the pancreas, transverse colon, and liver, were 58.1%, 18.6%, and 14.0%, respectively. The proportion of patients who exhibited distant metastases was 44.2%, and R0 resection was achieved in 30.2% of patients. A total of 69.8% of patients underwent postoperative chemotherapy. The median survival rate was 12.3 months. Upon multivariate analysis, the presence of distant metastases (P = 0.01, HR; 3.48), the use of postoperative chemotherapy (P = 0.0004, HR; 0.12), and R0 resection (P < 0.0001, HR; 0.14) were significantly correlated with OS. Patients who did not undergo postoperative chemotherapy showed significantly higher levels of inflammatory parameters and lower levels of nutritional parameters 4 weeks after surgery than those who did. CONCLUSIONS We evaluated that the presence of distant metastases was significantly associated with a poor prognosis, and the use of postoperative chemotherapy and R0 resection was significantly associated with a better prognosis in patients with T4b GC. It would be more important for a T4b GC treatment to balance between therapeutic tolerance for postoperative chemotherapy and surgical therapeutic effect.

Abstract
Introduction Adrenocortical carcinoma (ACC) is an extremely rare and aggressive tumor, and its clinical characteristics are poorly defined because of its rarity. Case Presentation We report a 64-year-old man who presented with upper abdominal pain and weight loss. Computed tomography revealed a 15 cm left adrenal tumor compressing the pancreas ventrally and a tumor thrombus in the inferior vena cava (IVC) originating from the left renal vein. Positron emission tomography-computed tomography revealed 18F-fluorodeoxyglucose uptake only in the tumor and tumor thrombus, and radical surgery was planned. Intraoperatively, the tumor was visible on the posterior stomach wall, and the tumor adhered to the pancreas and left kidney. We excised the tumor with part of the pancreas and the left kidney and excised the thrombus from the IVC after clamping. The final diagnosis was ACC, tumor-node-metastasis grade T3N1M0, stage III. The patient received chemotherapy and radiotherapy postoperatively; however, two liver metastases appeared 6 months after surgery. Chemotherapy was continued, and no exacerbation of the liver metastases was observed. Posterior segment resection of the liver was performed 16 months after the initial surgery. Conclusion This report of a rare case of ACC involving the pancreas with tumor thrombus extension to the IVC stresses that this combination of conditions does not preclude radical surgery. However, more data are needed regarding chemotherapy and radiotherapy, as well as relapse treatment, and further research on ACC is essential for a favorable prognosis.

Abstract
Alternative splicing in the 3'UTR of mammalian genes plays a crucial role in diverse biological processes, including cell differentiation and development. SAM68 is a key splicing regulator that controls the diversity of 3'UTR isoforms through alternative last exon (ALE) selection. However, the tissue/cell type-specific mechanisms underlying the splicing control at the 3' end and its functional significance remain unclear. Here, we show that SAM68 regulates ALE splicing in a dose-dependent manner and the neuronal splicing is differentially regulated depending on the characteristics of the target transcript. Specifically, we found that SAM68 regulates interleukin-1 receptor-associated protein splicing through the interaction with U1 small nuclear ribonucleoprotein. In contrast, the ALE splicing of protocadherin-15 (Pcdh15), a gene implicated in several neuropsychiatric disorders, is independent of U1 small nuclear ribonucleoprotein but modulated by the calcium/calmodulin-dependent protein kinase signaling pathway. We found that the aberrant ALE selection of Pcdh15 led to a conversion from a membrane-bound to a soluble isoform and consequently disrupted its localization into excitatory and inhibitory synapses. Notably, the neuronal expression of the soluble form of PCDH15 preferentially affected the number of inhibitory synapses. Moreover, the soluble form of PCDH15 interacted physically with α-neurexins and further disrupted neuroligin-2-induced inhibitory synapses in artificial synapse formation assays. Our findings provide novel insights into the role of neuron-specific alternative 3'UTR isoform selections in synapse development.

Abstract
Anaplastic carcinoma of the pancreas (ACP) is an aggressive pancreatic tumor that grows rapidly, and its clinical characteristics are poorly defined because of its rarity. Thus, preoperative diagnosis is difficult and most definitive diagnoses are generally made by surgery, highlighting the importance of collecting more cases of ACP. We report a case of a 79-year-old woman with ACP that was difficult to diagnose preoperatively. Abdominal enhanced computed tomography revealed a large and expansive tumor in the spleen containing multilocular cystic and solid components. The first preoperative diagnosis was splenic angiosarcoma, and the tumor could be resected by distal pancreatectomy, total gastrectomy and partial transverse colectomy. ACP was first diagnosed based on postoperative histopathological findings. ACP that spreads to the spleen and forms an intrasplenic mass is rare. However, ACP should be included in the differential diagnosis of such patients, and further research of ACP is essential for a favorable prognosis.

Abstract
A 62-year-old male presented with right intercostal muscle pain. Clinical examination revealed muscular defense in the same area. Abdominal ultrasonography revealed a distended gallbladder and ascites effusion, but no gallstones or polyps were present. Contrast-enhanced computerized tomography was performed, which revealed luminal obstruction due to arterial dissection of the celiac artery and intrinsic hepatic artery. This finding suggested gangrenous cholecystitis; thus, urgent cholecystectomy was performed. Only a few cases of celiac artery dissection and only one case of gangrenous cholecystitis without stones have been reported. We report here an extremely rare case of celiac artery dissection.

Abstract
BACKGROUND/AIM This study aimed to evaluate the relationship between clinical outcomes and intra-tumoral fibroblast growth factor receptor 2 (FGFR2) expression in human epidermal growth factor receptor 2 (HER2)-positive gastric cancer (GC) patients who had undergone HER2-targeted chemotherapy. PATIENTS AND METHODS A retrospective analysis was performed in 22 patients with HER2-positive GC, who had undergone systemic chemotherapy. We performed immunohistochemistry staining of FGFR2 expression using surgically resected specimens or biopsied samples and evaluated clinicopathological characteristic and overall survival (OS) in the FGFR2-negative and -positive GC groups. RESULTS A total of 8 and 14 patients were placed in the FGFR2-negative and -positive group, respectively. The median OS rates were 56.2 and 16.0 months in the FGFR2-negative and -positive groups, respectively. The FGFR2-negative group had a significantly better prognosis after HER2-targeted chemotherapy [p=0.027 (log-rank test)]. The univariate analysis revealed that performing gastrectomy, response to combination chemotherapy with trastuzumab, and FGFR2 positivity were significantly correlated with OS. In a multivariate analysis, the response to combination chemotherapy with trastuzumab (p=0.008) was significantly correlated with OS. In addition, the proportions of patients who showed CR or PR in response to chemotherapy were 87.5 and 42.9% in the FGFR2-negative and -positive groups, respectively (p=0.031). CONCLUSION HER2-positive GC patients, without overexpression of FGFR2, exhibited an improved prognosis and response rate to trastuzumab combination chemotherapy. Assessment of intra-tumoral FGFR2 expression could be helpful in predicting the prognosis and response to trastuzumab in HER2-positive GC patients.

Abstract
Gallbladder torsion is a rare and potentially fatal condition presenting with acute abdominal pain. Gallbladder torsion requires early diagnosis and treatment; however, preoperative diagnosis is difficult. In the present case, magnetic resonance cholangiopancreatography provided definitive imaging findings and was very useful in making the preoperative diagnosis.

Abstract
BACKGROUND/AIM Following oxaliplatin-based chemotherapy, approximately half of all colorectal cancer patients develop sinusoidal obstruction syndrome (SOS). SOS can be monitored by measuring splenic volume; however, obtaining this measurement is not a simple process. In this study, we evaluated changes in hyaluronic acid (HA) concentrations as a simpler marker of SOS. PATIENTS AND METHODS We measured splenic volume and laboratory data, including hyaluronic acid concentration, liver enzymes, and platelet counts, in 34 patients with colorectal cancer who underwent radical resection and who received capecitabine plus oxaliplatin (CapeOx) chemotherapy. RESULTS A strong correlation was identified between ≥30% increase in splenic volume and significantly elevated HA concentrations. Affected patients also had persistent thrombocytopenia and liver dysfunction compared to patients without elevated HA concentration. CONCLUSION HA concentration may predict SOS in patients who receive CapeOx adjuvant chemotherapy.

Abstract
A 73-year-old woman presented to our hospital because of painful bulging in the right lower abdomen, and developed a 17 × 12 cm incisional hernia after kidney transplantation using right oblique incision. Laparoscopic intraperitoneal onlay mesh (IPOM) repair was performed. Since a transplanted kidney is close to the abdominal wall defect, the space between the transplanted kidney and the abdominal wall was peeled off to secure enough space for the mesh to be place. After that the fascial defect was detected precisely, and the polypropylene-polyglycolic acid composite mesh was fixed with 3 cm overlapping of the hernia ring by non-absorbable tacks. The patient was discharged 9 days after surgery. In general, abdominal incisional hernias after kidney transplantation are relatively large with boundary defect of abdominal wall ensuing between the abdominal and allograft. However, laparoscopic IPOM repair of incisional hernia after kidney transplantation can be performed safely and effectively.

Abstract
We investigated the effect of chemoradiotherapy(CRT)on pancreatic cancer and the significance of preoperative chemoradiotherapy( NACRT)on resectable pancreatic cancer. The subjects were 36 patients who underwent CRT for locally advanced pancreatic cancer experienced in our department in the past 12 years(. 1)Regarding the antitumor effect of CRT, tumor diameter, tumor marker, and FDG for PET examination were reduced in 72%, 81%, and 96% of cases, respectively. In addition, the effect of Grade 1b plus 2 was observed in 10 of 16 patients who were resected after CRT(response rate 63%). In these successful cases, irradiation of 40 Gy or more and oral administration of S-1 1,500 mg or more were performed during this period. In addition, the survival rate of the NACRT plus S group(16 cases)was the same as that of the SF group (20 cases)of cStage ⅡA or lower at the same time, 50% survival was longer, and local recurrence was less. Based on the above, preoperative chemoradiotherapy combined with S-1 for resectable pancreatic cancer may be a promising preoperative treatment in the future.

Abstract
The potent splicing inhibitor spliceostatin A (SSA) inhibits cell cycle progression at the G1 and G2/M phases. We previously reported that upregulation of the p27 cyclin-dependent kinase inhibitor encoded by CDKN1B and its C-terminal truncated form, namely p27*, which is translated from CDKN1B pre-mRNA, is one of the causes of G1 phase arrest caused by SSA treatment. However, the detailed molecular mechanism underlying G1 phase arrest caused by SSA treatment remains to be elucidated. In this study, we found that SSA treatment caused the downregulation of cell cycle regulators, including CCNE1, CCNE2, and E2F1, at both the mRNA and protein levels. We also found that transcription elongation of the genes was deficient in SSA-treated cells. The overexpression of CCNE1 and E2F1 in combination with CDKN1B knockout partially suppressed G1 phase arrest caused by SSA treatment. These results suggest that the downregulation of CCNE1 and E2F1 contribute to the G1 phase arrest induced by SSA treatment, although they do not exclude the involvement of other factors in SSA-induced G1 phase arrest.

Abstract
BACKGROUND/AIM A significant predictive factor for the occurrence of complications after gastrectomy in elderly gastric cancer patients is yet to be determined. We aimed to evaluate the clinical factors associated with overall complications including remote infection after gastrectomy in elderly gastric cancer patients. PATIENTS AND METHODS We retrospectively analyzed data of 101 patients aged over 80 years, who underwent curative gastrectomy. We analyzed the clinicopathological factors that were independently associated with the occurrence of overall complications or remote infection by a logistic regression model. RESULTS The overall complication rate was 24.8%. We identified pneumonia as a remote infection, and the occurrence rate of remote infections was 5.9%. On multivariate analysis, hemoglobin (<11 g/dl) and operation time (>240 min) were significantly correlated with the occurrence of overall complications. Regarding the occurrence of remote infection, performing total gastrectomy and a hemoglobin level <11 g/dl were identified as significant risk factors. CONCLUSION Preoperative anemia and intraoperative factors, including the surgical procedure, could affect the occurrence of postoperative complications in elderly patients.

Abstract
BACKGROUND The relationship between chronological nutritional changes and development of fatty liver after total gastrectomy (TG) in gastric cancer (GC) patients is still unclear. This study aimed to evaluate relationship between development of fatty liver and chronological changes of nutritional parameters during 12 months after TG. METHODS We retrospectively analyzed medical records of 59 patients with GC who underwent TG at the Kanazawa Medical University Hospital between January 2009 and December 2017. We defined fatty liver change as a mean liver-to-spleen attenuation ratio (L/S ratio) of less than 1.2 in the computed tomography images at 12 months after TG and divided the patients into fatty liver (FL) and non-FL groups from the L/S ratio. We analyzed serum levels of total protein and albumin, and psoas muscle index (PMI) before TG and at 6 and 12 months after TG in the non-FL and FL groups. RESULTS Six patients showed an L/S ratio of less than 1.2 at 12 months after TG and were included into FL group. There was no significant difference between the groups in serum parameters, L/S ratio, and PMI before TG. In the FL group, the mean levels of total protein and albumin decreased after TG and were significant lower at 6 months, compared with the non-FL group. And then, these levels in the FL group recovered at 12 months. In contrast, the mean levels of total protein and albumin in the non-FL group did not decrease below the preoperative levels throughout the year after surgery. As with laboratory parameters, all patients in the FL group showed decrease of PMI at 6 months after TG. This proportion was significantly higher than that in the non-FL group (100% vs. 40.8%, P = 0.006). CONCLUSIONS We evaluated that the patients with fatty liver occurring after TG had significantly lower levels of serum nutritional parameters and skeletal muscle index at 6 months, not but 12 months, after TG.

Abstract
INTRODUCTION In patients with gastric cancer, 6-27% of patients are diagnosed with T4b disease that invades adjacent organs, and curative resection can improve the prognosis of these patients. CASE PRESENTATION A 70-year-old Japanese man presented with an abdominal tumor and was diagnosed with advanced gastric cancer (L-Circ type 3 T4b N2 M0 H0 stage IVA, based on the 15th edition of the Japanese Classification of Gastric Carcinoma) with extensive abdominal wall invasion. We performed open gastrojejunal bypass for gastric obstruction and initiated a chemotherapeutic regimen comprising S-1 (120 mg/day) and oxaliplatin (100 mg/m2). Upper gastrointestinal endoscopy performed after the administration of six courses of the S-1 and oxaliplatin regimen revealed a persistent primary lower gastric wall lesion; however, the diameter of the abdominal wall invasion and metastatic lymph nodes was significantly reduced, in addition to decreased serum carcinoembryonic antigen and carbohydrate antigen 19-9 levels. Subsequently, the patient underwent distal gastrectomy with D2 lymphadenectomy combined with transverse colon and abdominal wall resection. We performed radical en bloc resection and achieved a tumor-free resection margin. Simple abdominal wall closure was performed without mesh or musculocutaneous flap placement. Histopathological examination of the resected tumor specimen showed direct invasion of the mesocolon and rectus abdominis muscle. The patient was postoperatively diagnosed with L Gre-Ant type5 T4b (SI: rectus abdominis muscle) N2 PM0 DM0 Stage IIIA R0 Grade 2a gastric cancer based on histopathological findings and received S-1 as adjuvant chemotherapy, 2 months postoperatively. No recurrence was detected 6 months postoperatively. CONCLUSIONS We report a case of advanced gastric cancer with extensive abdominal wall invasion that was successfully treated with gastrectomy combined with resection of adjacent organs showing tumor invasion after effective systemic chemotherapy. A therapeutic approach comprising curative surgery combined with perioperative chemotherapy is useful in patients with T4b gastric cancer.

Abstract
RNA splicing, a highly conserved process in eukaryotic gene expression, is seen as a promising target for anticancer agents. Splicing is associated with other RNA processing steps, such as transcription and nuclear export; however, our understanding of the interaction between splicing and other RNA regulatory mechanisms remains incomplete. Moreover, the impact of chemical splicing inhibition on long non-coding RNAs (lncRNAs) has been poorly understood. Here, we demonstrate that spliceostatin A (SSA), a chemical splicing modulator that binds to the SF3B subcomplex of the U2 small nuclear ribonucleoprotein particle (snRNP), limits U1 snRNP availability in splicing, resulting in premature cleavage and polyadenylation of MALAT1, a nuclear lncRNA, as well as protein-coding mRNAs. Therefore, truncated transcripts are exported into the cytoplasm and translated, resulting in aberrant protein products. Our work demonstrates that active recycling of the splicing machinery maintains homeostasis of RNA processing beyond intron excision.

Abstract
We investigated 34 cases of preoperative chemoradiotherapy(CRT)for locally advanced pancreatic cancer including resectable pancreatic cancer in our department during the past 11 years. For resectable(R)or borderline resectable(BR)pancreatic cancer, survival curves were generally higher in the CRT plus S-1 group treated after CRT than in the CRT group treated with post-CRT chemotherapy, but there was no statistically significant difference. In non-resected cases, local exacerbation was observed, which was one of the causes of a decline in terminal QOL. From the above, at present, it is desirable to remove R or BR pancreatic cancer after CRT, but the significance of surgery may change in the future due to the improvement of multidisciplinary treatment.

Abstract
Pre-mRNA splicing is an essential mechanism for ensuring integrity of the transcriptome in eukaryotes. Therefore, splicing deficiency might cause a decrease in functional proteins and the production of nonfunctional, aberrant proteins. To prevent the production of such aberrant proteins, eukaryotic cells have several mRNA quality control mechanisms. In addition to the known mechanisms, we previously found that transcription elongation is attenuated to prevent the accumulation of pre-mRNA under splicing-deficient conditions. However, the detailed molecular mechanism behind the defect in transcription elongation remains unknown. Here, we showed that the RNA binding protein Rbm38 reduced the transcription elongation defect of the SMEK2 gene caused by splicing deficiency. This reduction was shown to require the N- and C-terminal regions of Rbm38, along with an important role being played by the RNA-recognition motif of Rbm38. These findings advance our understanding of the molecular mechanism of the transcription elongation defect caused by splicing deficiency.

Abstract
Background: Nivolumab has been approved for use in advanced gastric cancer (GC) after third-line chemotherapy in Japan. However, it remains difficult to predict favorable nivolumab response before treatment. Methods: We evaluated the clinical course with a focus on the chronological changes in neutrophil/lymphocyte ratio (NLR) throughout the chemotherapy and assessed the relationship between nivolumab response and chronological changes in NLR before nivolumab administration. Results: We experienced nine cases who received nivolumab monotherapy for unresectable advanced or postoperative recurrent GC. Nivolumab was used as third-line chemotherapy in all patients, and partial response (PR) and stable disease (SD) were observed in two patients each. Nivolumab treatment resulted in progressive disease (PD) in five patients. In patients with PR or SD, changes in the NLR tended to correspond to the response of target metastatic lymph nodes to first- and second-line chemotherapy. In the four cases with PR or SD following nivolumab, ∆NLRresponses that was the difference in the degree of decline during the most effective pretreatment chemotherapy were 1.39, 0.73, 1.62, and 1.22. However, the patients with PD showed lower ∆NLRresponses, at 0.66, 0.66, 0.25, 0.13, and -0.05 in the five cases. Mean ∆NLRresponses in the patients with PR or SD and patients with PD were 1.17 and 0.33, respectively (P = 0.0008). Conclusions: We experienced nine GC cases treated with nivolumab and assessed the association between chronological NLR changes throughout chemotherapy and tumor response to nivolumab. Changes in NLR during pretreatment chemotherapy might predict tumor response to nivolumab monotherapy in patients with advanced GC.

Abstract
A 66-year-old man was diagnosed with advanced gastric cancer(L, Less, Type 2, T4a[SE], N2, M1[LYM], H0, P0, cStage Ⅳ)and received treatment with S-1/cisplatin as first-line chemotherapy. This treatment resulted in partial response(PR) after 3 months, with reduction in the sizes of metastatic lymph nodes surrounding the pancreatic head and paraaortic lesion. However, the sizes of metastatic lymph nodes increased after 7 months of chemotherapy. Ramucirumab/nab-paclitaxel was then administered as second-line chemotherapy, and the diameter of the metastatic lymph nodes subsequently decreased after 4 months of the regimen. However, progressive disease was observed at 7 months, and blood transfusion was required because of bleeding from the primary gastric tumor. Therefore, nivolumab was initiated as third-line chemotherapy 14 months after the first treatment. After nivolumab administration, a 28% reduction in metastatic lymph nodes was achieved within 3 months, together with the regression of the primary gastric tumor and improvement in anemia within 6 months. PR was achieved after 12 months of nivolumab administration, and effective disease control was maintained for 16 months without any adverse reaction to nivolumab.

Abstract
A 48-year-old woman was admitted to our hospital because of upper abdominal pain. Computer tomography showed an enhancing mass in the pancreatic body, dilation of the main pancreatic duct (MPD) and a filling defect within the splenic vein. On the basis of the preoperative diagnosis of pancreatic body cancer, distal pancreatectomy was scheduled. The pancreas was divided along the left edge of the gastroduodenal artery; however, frozen pathological examination of the pancreatic stump was tumor positive, and therefore a total pancreatectomy was performed. The lesion was a white expansive nodular mass that had spread into the MPD and protruded into the splenic vein. A pathological diagnosis of non-functioning neuroendocrine tumor (NET) was made. In general, imaging findings of disruption of the MPD and tumor vein thrombus are characteristics of pancreatic ductal adenocarcinoma, but are uncommon in NET. However, NET should be included in the differential diagnosis for such patients.

Abstract
BACKGROUND/AIM We evaluated whether splenic volume (SV) predicts sinusoidal obstruction syndrome (SOS) in colorectal cancer (CRC) patients receiving capecitabine plus oxaliplatin (CapeOX) therapy. PATIENTS AND METHODS In this retrospective study, we measured SV in 41 patients receiving adjuvant CapeOX for CRC at five different time points. We compared the clinical data of the 18 patients who experienced ≥30% increases in SV immediately after vs. before CapeOX (group A) with data for the remaining 23 patients (group B). RESULTS Platelet numbers decreased and the levels of hepatobiliary enzymes increased significantly 1 year after CapeOX compared with before CapeOX in group A. However, in group B, significantly decreased platelet numbers and significantly increased aspartate transaminase levels were confirmed only immediately after CapeOX, with no significant subsequent changes. CONCLUSION SV was significantly associated with thrombocytopenia and liver dysfunction in CRC patients, and predicted SOS.

A 71-year-old woman was diagnosed with advanced gastroesophageal junction cancer with bulky lymph nodes along the cardiac region and the lower mediastinum (GE-Circ type 3 T3 N3 M0 H0 stage III) and received treatment with S-1 and oxaliplatin (SOX) as first-line chemotherapy. After 3 cycles of SOX, severe anorexia and diarrhea were observed. We converted from this regimen of systemic chemotherapy to ramucirumab (RAM) monotherapy as second-line chemotherapy. This treatment resulted in a reduction in size of the metastatic lymph nodes along the cardiac region and the lower mediastinum. However, progression of lymph node metastasis and the primary tumor was observed following 7 months of RAM monotherapy. Therefore, nivolumab was initiated as third-line chemotherapy 14 months after the initial treatment. After 3 months of nivolumab administration, a 47% reduction in metastatic lymph nodes was achieved and a regression of the primary gastric tumor as seen on an enhanced computed tomography scan. After 7 months of nivolumab monotherapy, the diameter of the target lymph nodes had reduced by 81% from baseline, and there was no evidence of malignancy upon pathological assessment of the primary tumor site biopsy. The patient survived with nivolumab monotherapy for approximately 2 years after her first visit, without any adverse reaction to nivolumab.

Abstract
BACKGROUND The use of staging laparoscopy (SL) has become widespread in patients with advanced gastric cancer (GC). This study aimed to evaluate the predictive value of the neutrophil/lymphocyte ratio (NLR) for the presence of peritoneal metastasis during staging laparoscopy in patients with advanced GC. METHODS This retrospective analysis was performed in 35 patients with advanced GC who underwent SL at Kanazawa Medical University Hospital between January 2009 and December 2017. Clinicopathological characteristics were examined and multivariate analyses were performed to identify preoperative laboratory parameters that were independently associated with the presence of peritoneal metastasis or cytological malignancy (P/CY positive) during SL. RESULTS A P/CY-positive result was confirmed during SL in 16 patients (45.7%). Patients with type 4 or diffuse type 3 tumors showed a significantly higher P/CY-positive rate than those with other tumor types (58.3% vs. 18.2%, P = 0.02). In the univariate analysis for preoperative laboratory parameters, NLR (P < 0.0001) and total protein (P = 0.03) and albumin (P = 0.04) levels were significantly correlated with a P/CY-positive result. On multivariate analysis, NLR was significantly correlated with a P/CY-positive result (P = 0.0002). In patients with type 4 or diffuse type 3 tumors, a high NLR (> 3.5) was associated with a significantly higher P/CY-positive rate than a low NLR (≤ 3.5) (83.3% vs. 33.3%, P = 0.01). Moreover, in patients without type 4 or diffuse type 3 tumors, the P/CY-positive rates were 100% and 0% in patients with NLR > 3.5 and NLR ≤ 3.5, respectively. CONCLUSIONS The preoperative NLR was a significant independent predictor of the presence of peritoneal metastasis during SL. Regardless of tumor type, patients with a high NLR could be reasonable candidates for SL. On the other hand, non-diffuse type tumor accompanied by a low NLR may not need to undergo SL.

Abstract
BACKGROUND We evaluated the efficacy of surgical resection following response to primary chemotherapy for prospective registered Stage IV gastric cancer patients. PATIENTS AND METHODS We analyzed the details and prognosis of 6 patients having advanced gastric cancer clinically diagnosed as resectable following primary chemotherapy between 2011 and 2015. RESULTS The reason for being diagnosed as unresectable before chemotherapy was metastasis to distant sites, including paraaortic lymph node metastasis in 3 cases, peritoneal metastasis in 2 cases, and liver metastasis in 1 case.Two patients were able to undergo R0 resection, and the remaining 4 patients were unable to undergo complete resection.The median survival time (MST)of the patients who underwent R0 resection was 567.5 days, and the MST of the patients who could not undergo R0 resection was 474 days. CONCLUSION Careful consideration of conversion gastrectomy may be important in inducing longterm survival in clinical Stage IV gastric cancer patients.

Abstract
Spliceostatin A (SSA) is a methyl ketal derivative of FR901464, a potent antitumor compound isolated from a culture broth of Pseudomonas sp no. 2663. These compounds selectively bind to the essential spliceosome component SF3b, a subcomplex of the U2 snRNP, to inhibit pre-mRNA splicing. However, the mechanism of SSA's antitumor activity is unknown. It is noteworthy that SSA causes accumulation of a truncated form of the CDK inhibitor protein p27 translated from CDKN1B pre-mRNA, which is involved in SSA-induced cell-cycle arrest. However, it is still unclear whether pre-mRNAs are uniformly exported from the nucleus following SSA treatment. We performed RNA-seq analysis on nuclear and cytoplasmic fractions of SSA-treated cells. Our statistical analyses showed that intron retention is the major consequence of SSA treatment, and a small number of intron-containing pre-mRNAs leak into the cytoplasm. Using a series of reporter plasmids to investigate the roles of intronic sequences in the pre-mRNA leakage, we showed that the strength of the 5' splice site affects pre-mRNA leakage. Additionally, we found that the level of pre-mRNA leakage is related to transcript length. These results suggest that the strength of the 5' splice site and the length of the transcripts are determinants of the pre-mRNA leakage induced by SF3b inhibitors.

Abstract
BACKGROUND The prognosis after neoadjuvant chemotherapy(NAC)is expected to improve in patients with resectable advanced gastric cancer who are at high risk of recurrence or those with unfavorable prognostic factors. PATIENTS AND METHODS This retrospective study examined treatment outcomes and survival of 25 patients with advanced gastric cancer who received NAC with S-1 and cisplatin(CDDP)between October 2008 and December 2015. RESULTS Among patients with clinical Stage II (4 patients)and III (21 patients)tumors, 13 had partial response(PR)and 12 had stable disease(SD). Neither complete response(CR)nor progressive disease(PD)was noted. CR of lymph node metastases was observed in 6 patients, PR in 9 patients, and SD in 7 patients. R0 resection was performed in 16 patients, R1 in 3 patients, and R2 in 6 patients. Histologic grades of primary tumors were Grade 0(1 patient), Grade 1a(16 patients), Grade 1b(5 patients), Grade 2(3 patients), and Grade 3(none). The 3-year survival rate after R0 resection was 46%, 3-year progression-free survival rate was 68%, and 3-year recurrence-free survival rate was 69%. Significant differences were observed for pathologic stages ypN0/1, 2, and 3(p=0.04), tumor down-stage(p=0.02), and overall tumor fStage I , II / III , and IV (p<0.01). CONCLUSION It is conceivable that R0 resection and downstaging after NAC will improve prognosis.

Abstract
We report a case of a radical resection of cT3a gallbladder cancer after neoadjuvant chemotherapy(NAC). A 68-year-old man was referred to our hospital with a chief complaint of right hypochondralgia.Imaging findings were consistent with acute cholecystitis with a stone at the neck of the gallbladder, and advanced gallbladder cancer with infiltration into segments 4 and 5 from the fundus of the gallbladder, Gfb, cT3a(liver), cN1(8a), cM0, cStage III B, was diagnosed on staging laparoscopy. The patient received 3 courses of GEM plus CDDP NAC.The response to the treatment included reduction of the main tumor by 35%, diminished accumulation of FDG at the 8a lymph node, and decrease in serum CA19-9, from 163 U/mL to 75 U/mL. Cholecystectomy with the gallbladder bed and regional lymphadenectomy were performed.The histologic examination revealed extensive necrosis and degeneration of cancer cells in the infiltrating lesions, and the therapeutic effect was judged as Grade I b.The patient has now survived for 11 months without recurrence.

Abstract
Most eukaryotic precursor mRNAs are subjected to RNA processing events, including 5′‐end capping, splicing and 3′‐end processing. These processing events were historically studied independently; however, since the early 1990s tremendous efforts by many research groups have revealed that these processing factors interact with each other to control each other's functions. U1 snRNP and its components negatively regulate polyadenylation of precursor mRNAs. Importantly, this function is necessary for protecting the integrity of the transcriptome and for regulating gene length and the direction of transcription. In addition, physical and functional interactions occur between splicing factors and 3′‐end processing factors across the last exon. These interactions activate or inhibit splicing and 3′‐end processing depending on the context. Therefore, splicing and 3′‐end processing are reciprocally regulated in many ways through the complex protein–protein interaction network. Although interesting questions remain, future studies will illuminate the molecular mechanisms underlying the reciprocal regulation.

Abstract
A 57-year-old woman was diagnosed with a pancreatic tumor. Abdominal computed tomography showed cStage Ⅳa pancreatic cancer with a 20×16 mm tumor near the base of the celiac artery. Since the tumor contacted the SMA at an angle of 90 degrees, it was judged as a borderline resectable tumor. In addition, cStage ⅠB gastric cancer was found in the corpus ventriculi. Since the patient had a respiratory complication, a distal pancreatectomy with celiac axis resection in combination with a total gastrectomy was considered too aggressive for this patient. Therefore, she received chemoradiotherapy prior to the surgery. Distal pancreatectomy with D2 lymphadenectomy and subtotal gastrectomy with lower left phrenic artery preservation was performed. This case involved a considerable extension of the disease and radical surgery; however, currently the patient's prognosis and QOL are good.

Abstract
BACKGROUND Esophageal bypass surgery is palliative surgery for unresectable esophageal cancer with esophageal stenosis, which often leads to poor nutrition. We investigated the clinical characteristics, nutritional status, and outcomes of patients who underwent esophageal bypass surgery. PATIENTS AND METHODS We reviewed 11 cases of esophageal bypass surgery for unresectable esophageal cancer performed in our hospital between 1992 and 2015, and we examined the surgical outcome along with preoperative nutritional assessment. RESULTS There were 1, 9, and 1 cases of cStage Ⅲ, Ⅳa, and Ⅳb, respectively. For the bypass, a gastric tube was used in 8 cases and colon reconstruction in 3. Postoperative complications were 1 case of recurrent laryngeal nerve palsy (9%), 4 cases of anastomotic leakage (36%), and 4 cases of pneumonia (36%). The preoperative nutritional status (total protein, albumin, and cholinesterase levels) in the esophageal bypass group (n=11) was significantly worse than that in the esophagectomy group (n=40). The median survival of all patients (n=11) was 5.7 months. Patients receiving induction chemoradiotherapy followed by bypass surgery (n=7) had a median survival of 15.2 months. CONCLUSION Since patients undergoing esophageal bypass surgery often present with malnutrition, attention to anastomotic leakage and infectious complications is necessary.

Abstract
We present a successful case of treatment of colonic metastasis and peritoneal recurrence of type 4 gastric cancer by using colectomy and chemotherapy. A 70-year-old woman with a diagnosis of type 4 advanced gastric cancer underwent distal gastrectomy. The final pathological diagnosis was LM, circ, type 4, sig, pT4a (SE), ly1, v1, pN1, M0, P0, CY0, pStage Ⅲa. Adjuvant chemotherapy was conducted with oral administration of S-1, though regrettably the chemotherapy was interrupted because of diarrhea, an adverse effect of S-1. Metastatic recurrence occurred on the transverse colon, for which she underwent transverse colectomy 2.9 years after the initial surgery. Another colonic metastasis in the ascending colon along with peritoneal recurrence was diagnosed 3.11 years after the initial surgery, and the patient underwent a palliative colostomy and received chemotherapy with S-1 plus docetaxel. She was successfully treated up to a clinical CR with chemotherapy, and she died 5.10 years after the initial surgery. In this case, a good prognosis was obtained through the combination of resection of the recurrence sites, palliative surgery for avoiding obstruction, and chemotherapy using S-1 plus docetaxel for metachronous multiple metastases.

Abstract
Phosphorylation of the C-terminal domain of the largest subunit of RNA polymerase II (Pol II), especially Ser2 and Ser5 residues, plays important roles in transcription and mRNA processing, including 5′ end capping, splicing and 3′ end processing. These phosphorylation events stimulate mRNA processing, however, it is not clear whether splicing activity affects the phosphorylation status of Pol II. In this study, we found that splicing inhibition by potent splicing inhibitors spliceostatin A (SSA) and pladienolide B or by antisense oligos against snRNAs decreased phospho-Ser2 level, but had little or no effects on phospho-Ser5 level. In contrast, transcription and translation inhibitors did not decrease phospho-Ser2 level, therefore inhibition of not all the gene expression processes cause the decrease of phospho-Ser2. SSA treatment caused early dissociation of Pol II and decrease in phospho-Ser2 level of chromatin-bound Pol II, suggesting that splicing inhibition causes downregulation of phospho-Ser2 through at least these two mechanisms.

Abstract
Alternative splicing acts on transcripts from almost all human multi-exon genes. Notwithstanding its ubiquity, fundamental ramifications of splicing on protein expression remain unresolved. The number and identity of spliced transcripts that form stably folded proteins remain the sources of considerable debate, due largely to low coverage of experimental methods and the resulting absence of negative data. We circumvent this issue by developing a semi-supervised learning algorithm, positive unlabeled learning for splicing elucidation (PULSE; http://www.kimlab.org/software/pulse), which uses 48 features spanning various categories. We validated its accuracy on sets of bona fide protein isoforms and directly on mass spectrometry (MS) spectra for an overall AU-ROC of 0.85. We predict that around 32% of "exon skipping" alternative splicing events produce stable proteins, suggesting that the process engenders a significant number of previously uncharacterized proteins. We also provide insights into the distribution of positive isoforms in various functional classes and into the structural effects of alternative splicing.

Abstract
In eukaryotes, pre-mRNA splicing is an essential step for gene expression. We have been analyzing post-splicing intron turnover steps in higher eukaryotes. Here, we report protein interaction between human Debranching enzyme 1 (hDbr1) and several factors found in the Intron Large (IL) complex, which is an intermediate complex of the intron degradation pathway. The hDbr1 protein specifically interacts with xeroderma pigmentosum, complementeation group A (XPA)-binding protein 2 (Xab2). We also attempted to identify specific interactors of hDbr1. Co-immunoprecipitation experiments followed by mass spectrometry analysis identified a novel protein as one of the specific interactors of hDbr1. This protein is well conserved among many species and shows the highest similarity to yeast Drn1, so it is designated as human Dbr1 associated ribonuclease 1 (hDrn1). hDrn1 directly interacts with hDbr1 through protein–protein interaction. Furthermore, hDrn1 shuttles between the nucleus and the cytoplasm, as hDbr1 protein does. These findings suggest that hDrn1 has roles in both the nucleus and the cytoplasm, which are highly likely to involve hDbr1.

Abstract
A woman in her 70s was referred for examination of liver dysfunction. A cystic lesion with irregular contrast was observed at the pancreas head. The bile and pancreatic ducts were obstructed by the lesion. Part of the branch of the pancreatic duct at the pancreas head, continuous with the main pancreatic duct, was observed to be extended by using pancreatography. Pancreaticoduodenectomy was performed, and a diagnosis of invasive carcinoma from an intraductal papillary-mucinous neoplasm (IPMN) was made. Postoperative pathological diagnosis showed 16b1 inter-node metastasis. Liver and lung metastases were also detected after surgery; nevertheless, long-term survival was achieved for 5 years and 2 months by using various treatment modalities.

Abstract
BACKGROUND There is no standard regimen after failure of 5-fluorouracil and cisplatin-based first-line chemotherapy in patients with advanced or recurrent esophageal cancer. The feasibility of combination chemotherapy with docetaxel (DOC) and nedaplatin (CDGP) for these patients was retrospectively evaluated. METHODS Patients received DOC (30 mg/m² intra- venously) and CDGP (30-40 mg/m² intravenously) on days 1 and 15 of each 4-week period. The efficacy and toxicity of combination chemotherapy with DOC and CDGP in 13 patients was analyzed. RESULTS The patients received a median of 2 cycles of treatment(range, 1-23). The response and disease control rates were 8% and 54%, respectively. Grade 3 or 4 hematological toxicities were neutropenia, anemia, and thrombocytopenia, observed in 4(31%), 11(15%), and 2 patients (15%), respectively. Non-hematological toxicity, anorexia, was detected in only 1 patient(8%). No treatment-related death was observed. The median progression-free survival and overall survival were 3.2 and 11.6 months, respectively. CONCLUSIONS Combination chemotherapy with DOC and CDGP is considered a feasible regimen for refractory esophageal cancer.

Abstract
Pre-mRNA in eukaryotes is subjected to mRNA processing, which includes capping, polyadenylation, and splicing. Transcription and mRNA processing are coupled, and this coupling stimulates mRNA processing; however, the effects of mRNA processing on transcription are not fully understood. In this study, we found that inhibition of U2 snRNP by a splicing inhibitor, spliceostatin A (SSA), or by an antisense oligonucleotide to U2 snRNA, caused gene-specific 3′-end down-regulation. Removal of SSA from the culture media restored expression of the 3′ ends of genes, suggesting that U2 snRNP is required for expression of the 3′ end of genes. Finally, we found that SSA treatment caused accumulation of Pol II near the 5′ end of 3′-end down regulated genes, such as CDK6, SMEK2 and EGFR, indicating that SSA treatment led to transcription elongation arrest on these genes. These findings suggest that U2 snRNP is important for production of full length mRNA probably through regulation of transcription elongation, and that a novel checkpoint mechanism prevents pre-mRNA from accumulating as a result of splicing deficiencies, and thereby prevents production of aberrant proteins that might be translated from pre-mRNAs through the arrest of transcription elongation.

Abstract
BACKGROUND The standard treatment for Stage IV advanced gastric cancer (AGC) is systemic chemotherapy. Because patients who respond to induction chemotherapy seem to have a good prognosis, we converted the treatment strategy to gastrectomy( termed as conversion gastrectomy) in such patients. In this study, we estimated the outcomes of patients who underwent conversion gastrectomy for Stage IV AGC. METHODS We evaluated patients with Stage IV AGC who underwent conversion gastrectomy from October 2008 through September 2012 and retrospectively analyzed their clinicopathological variables and oncologic outcomes. RESULTS Twenty patients underwent conversion gastrectomy with an R0 resection rate of 45% (9/20). The median survival time (MST) was 18.0 months overall and did not differ significantly between patients with clinically stable disease( SD) and those with a partial response( PR)( 22.0 months vs 18.0 months, p=0.64). The MST was longer in patients with pathological Grade 1b-3 tumors than in those with Grade 1a tumors (47.8 months vs 16.3 months), and this difference was significant (p=0.04). Patients with R0 resection had a significantly longer MST than those with R1-2 ( 47.8 months vs 14.1 months ). CONCLUSIONS The present study provides evidence that patients with Stage IV AGC who undergo conversion gastrectomy with a histopathological response have a good prognosis and that R0 resection predicts longer survival.

Abstract
The patient was a 60-year-old man who had been admitted to our hospital because of elevated serum CA19-9 levels. Endoscopy revealed a Borrmann type 2 tumor of the jejunum. Computed tomography (CT) revealed lymph node metastases and peritoneal seeding. Hence, he was diagnosed with advanced jejunal cancer with distant metastasis (T4N1M0 stage). We performed partial resection of the jejunum, and he underwent chemotherapy with docetaxel( DOC) and S-1 for the peritoneal seeding postoperatively. Follow-up CT revealed that the chemotherapy was effective, and the patient achieved complete remission following 9 months of treatment.
