Abstract
e23122 Background: Breast cancer is the leading cancer among women both in US and Japan. Triple negative breast cancer (TNBC) is the subset of breast cancers that are negative for estrogen receptor (ER), progesterone receptor, and HER2. While the selective ER modulator tamoxifen or anti-HER2 therapy for breast cancer patients with ER positive or HER2 protein overexpression are the most successful examples of targeted therapies, only limited therapies are available for patients with TNBCs, which are associated with a poor prognosis. Advance in next-generation sequencing enables us to identify actionable driver mutations that can be potentially treated by targeted therapies in each cancer patient. The aim of this study is to examine actionable driver mutations in TNBCs in Japan by comprehensive genomic sequencing (CGS) with 435 gene panel, and compare the driver events in Japan with TCGA database to validate the utility of CGS. Methods: We examined all exons of 435 known cancer genes in Japanese TNBC patients (N = 53) by CGS and evaluated for concordance among independent data obtained from The Cancer Genome Atlas-TNBC whole exome sequencing database (N = 123). Results: Oncogenic driver mutations were identified in 51 of 53 Japanese patients (96%) with TNBC and 36 of 53 patients (67%) harbored mutations in genes associated with FDA-approved targeted therapies, indicating the potential clinical utility of a large gene panel for evaluating patients with TNBC. Among 80 total genetic alterations, frequently mutated genes ( > 10% patients) were TP53, PIK3CA and PTEN. Overall, the mutation spectrum of the Japanese patients is similar to that of the TCGA population, except amplification of MYC. Conclusions: Use of a CGS panel of 435 genes can reliably identify all of the critical mutations in TNBC patients, which are similar as TCGA data. The information derived from CGS can be used to determine the optimal treatment for TNBC patients.

Abstract
e15592 Background: Molecular heterogeneity represents a significant hurdle in realizing precision medicine for gastric cancer (GC). Large-scale whole exome sequencing projects have identified distinct molecular subtypes to help define the heterogeneity of GC. However, it remains unclear whether the targeted gene panel-based sequencing can provide optimum targeted therapies and clinical utility in GC. The aim of this study is to generate comprehensive genomic profiling data and classify Japanese GC into actionable clusters associated with targeted therapies. Methods: FFPE tumor tissues were obtained from surgical or biopsy specimens of 207 Japanese patients with GC. Extracted DNA was subjected to genomic sequencing for 435 cancer related genes including 69 druggable genes with FDA approved targeted therapies. Somatic mutations, copy number alterations (SCNA), microsatellite instability (MSI) and Epstein-Barr virus (EBV) infection were evaluated using sequencing data. Results: Genomic sequencing identified at least one alteration of 435 genes in 194 pts (94%), and that of 69 druggable genes in 141 pts (68%). The most frequently altered druggable gene was ERBB2 (14%), following BRCA2 (11%) and ATM (10%). We successfully classified 207 tumors into four molecular subtypes, similar to the previously report; EBV (4%), MSI (8%), chromosomal instability (58%) and genomically stable subtype (30%). Frequent alterations of druggable genes ( > 5%) were widely observed through these subtypes. To discover the novel classifications associated with targeted therapies, we classified 207 tumors using mutation rate and hierarchical clustering. We identified a hypermutated group (n = 32), and a remaining non-hypermutated group (n = 175) which were sub-divided into six clusters including five actionable ones; ERBB2 (n = 25), CDKN2A and CDKN2B (n = 10), KRAS (n = 10), BRCA2 (n = 9) and ATM cluster (n = 12). Interestingly, we experienced a case of unresectable GC with a remarkable response for anti-HER2 therapy in the ERBB2 cluster. Conclusions: Genomic sequencing using a 435-gene panel has the potential to provide the information of optimum targeted therapies for upcoming precision medicine in Japanese GC.

Abstract
Background A gastric adenosquamous carcinoma (ASC) that produces granulocyte-colony stimulating factor (G-CSF) is an uncommon malignancy with a poor prognosis. Due to the rarity of this lesion, a standard treatment for the disease has not been established. Case presentation We describe a case of a 66-year-old male with a G-CSF-producing gastric ASC who presented with severe anemia and leukocytosis. A radical resection was performed, followed by a course of adjuvant chemotherapy. Histopathologic examination revealed that the tumor consisted of areas of both squamous cell carcinoma and adenocarcinoma. Immunohistochemical staining with an anti-G-CSF antibody was also positive. He was started on adjuvant capecitabine and oxaliplatin (CapeOX) 6 weeks after surgery. The patient stopped treatment after 3 months due to his own preference. Eight months following surgery, the patient was found to have diffuse lymph node, liver, and peritoneal metastases. Conclusions G-CSF-producing gastric ASC is a rare and aggressive tumor. Because patients are usually diagnosed at an advanced stage, multidisciplinary evaluation and innovative treatments are needed. The rarity of this disease, with its aggressive features, poses a significant challenge in its treatment. In this brief case report, we summarize the management and outcomes of G-CSF-producing gastric ASC.

Abstract
PURPOSE Liver retransplantation is the only therapeutic option for patients with graft failure after liver transplantation. The aim of this study is to evaluate the outcomes of pediatric retransplantation from living donor at a single center. METHODS Between December 1998 to August 2015, retransplantation from a living donor was performed for 14 children (<18 years of age) at Kumamoto University Hospital. The characteristics of the retransplantation recipient and the clinicopathological factors between primary transplantation and retransplantation were analyzed to detect the prognostic factors. RESULTS In retransplantation, the operative time was longer and the amount of blood loss was greater in comparison to primary transplantation. The 1-, 3-, and 5-year survival rates from the date of retransplantation were 85.7, 85.7, and 78.6%, respectively. The rates of re-laparotomy after primary transplantation, bile leakage and postoperative bleeding after retransplantation were higher than after primary transplantation. Among the three patients who died after retransplantation, the operative time, the rate of re-laparotomy after primary transplantation and the incidence of gastrointestinal complications were higher in comparison to the surviving patients. CONCLUSION Pediatric retransplantation from a living donor is an acceptable procedure that could save the lives of recipients with failing allografts when organs from deceased donors are scarce. To ensure good results, it is essential to make an appropriate assessment of the cardiopulmonary function and the infectious state of the patients before Re-LDLT.

Abstract
Elucidating the interaction between cancer and non-cancer cells, such as blood vessels, immune cells, and other stromal cells, in the tumor microenvironment is imperative in understanding the mechanisms underlying cancer progression and metastasis, which is expected to lead to the development of new therapeutics. Sphingosine-1-phosphate is a bioactive lipid mediator that promotes cell survival, proliferation, migration, angiogenesis/lymphangiogenesis, and immune responsiveness, which are all factors involved in cancer progression. Sphingosine-1-phosphate is generated inside cancer cells by sphingosine kinases and then exported into the tumor microenvironment. Although sphingosine-1-phosphate is anticipated to play an important role in the tumor microenvironment and cancer progression, determining sphingosine-1-phosphate levels in the tumor microenvironment has been difficult due to a lack of established methods. We have recently developed a method to measure sphingosine-1-phosphate levels in the interstitial fluid that bathes cancer cells in the tumor microenvironment, and reported that high levels of sphingosine-1-phosphate exist in the tumor interstitial fluid. Importantly, sphingosine-1-phosphate can be secreted from cancer cells and non-cancer components such as immune cells and vascular/lymphatic endothelial cells in the tumor microenvironment. Furthermore, sphingosine-1-phosphate affects both cancer and non-cancer cells in the tumor microenvironment promoting cancer progression. Here, we review the roles of sphingosine-1-phosphate in the interaction between cancer and non-cancer cells in tumor microenvironment, and discuss future possibilities for targeted therapies against sphingosine-1-phosphate signaling for cancer patients.

Abstract
AIM The impact of neutrophil-to-lymphocyte ratio(NLR)changes on the outcome of chemotherapy for metastatic colorectalcancer (mCRC)was analyzed retrospectively. METHODOLOGY Twenty seven patients with unresectable mCRC were administered chemotherapy from January 2005 to December 2014 at the Niitsu Medical Center Hospital. The NLR was calculated from complete blood counts obtained prior to the administration of chemotherapy and at the best response. We defined the period with NLR≤2.5 as the totalintervalof NLR≤2.5. The impact of NLR on overallsurvivalwas determined using univariate and multivariate Cox regression models. RESULTS The median overall survival was 26 months in patients with an NLR≤5(n= 22), and 11 months in those with an NLR>5(n=5)before chemotherapy(p=0.03). The median overall survival was 31 months in patients with an NLR≤2.5(n=19), and 11 months in those with an NLR>2.5(n=8)at the best response(p< 0.001). The period with an NLR≤2.5 was found to correlate with overall survival(p<0.001). The period with an NLR≤2.5 was the only independent, statistically significant predictor of better survival in multivariate analysis(p=0.001). CONCLUSION The change of NLR may be a dynamic predictor of better survivalin patients with mCRC.

Abstract
Protein phosphorylation is the prime post-translational modification to drive cell division. Identification of phosphorylated proteins and their related kinases has uncovered molecular networks underlying mitotic processes, including chromosome assembly. Here we aimed to identify phosphoproteins from a mitotic chromosome-enriched lysate biochemically using mass spectrometry. We employed the Polo-box domain (PBD) of Polo-like kinase to tether phosphorylated proteins in the lysate. Resulting candidates included a number of chromosomal proteins that would not be identified unless using chromosome-enriched fractions. Among them, we focused to a chromokinesin KIF4A which becomes concentrated along the longitudinal axis of mitotic condensed chromatids. We found that KIF4A is phosphorylated specifically during mitosis, depending on the activity of Cdk1 and Aurora B, which turned out to be required for KIF4A to interact with condensin I. The molecular link between KIF4A and condensin raises an interesting possibility that the interaction of two distantly related ATPases is triggered by mitotic phosphorylation.

Abstract
We herein report the case of a rapidly progressive sporadic mesenteric desmoid tumor (DT). A 62-year-old woman presented with a 4-cm-diameter palpable mass in the left supraumbilical area. The mass showed an ill-defined margin with heterogeneous delayed enhancement on computed tomography and heterogeneous high intensity on T2-weighted magnetic resonance imaging. Sixteen months after the initial observation, the mass had grown in size, reaching 13 cm in diameter. The resected mass was histologically confirmed as a DT of the mesentery. Since DT often has an unpredictable clinical course, clinicians should bear in mind the need for imaging follow-up.

Abstract
This experiment was undertaken to assess the meiotic and developmental competences of oocytes derived from different sized follicles and denuded of cumulus cells 0, 20, and 44 h after the start of culture for in vitro maturation (IVM). Groups of 60 oocyte-cumulus complexes from small- (SF; <3 mm) and medium-sized follicles (MF; 3–6 mm) were cultured for IVM in porcine oocyte medium with 50 μM β-mercaptoethanol supplemented with 1 mM dibutyryl-cyclic adenosine monophosphate, 10 IU mL−1 of eCG, and 10 IU mL−1 of hCG for 20 h at 39°C and 5% CO2 in air. Then, after washing, they continued culture in fresh β-mercaptoethanol without dibutyryl-cyclic adenosine monophosphate and gonadotropins under the same conditions for another 24 h. At 0, 20, and 44 h of IVM, cumulus cells were removed with 0.1% (wt/vol) hyaluronidase and the denuded oocytes continued IVM culture following the protocol. Mature oocytes with the first polar body were selected, parthenogenetically activated with a single electrical pulse (DC: 1.2 kV/cm, 30 µs), incubated with 4% (wt/vol) BSA and 5 μM cytochalasin B for 4 h, and cultured in porcine zygote medium for 5 days. Cleavage and blastocyst formation rates were observed on Day 2 and 5, respectively. Blastocysts were stained with 4’,6-diamidino-2-phenylindole for cell count assessment. The experiment was replicated 5 times and analysed with a 1- or 2-way ANOVA. If P < 0.05 in ANOVA, a Tukey multiple comparisons test was performed. Regardless of the time of cumulus cell removal, oocytes from MF had significantly higher in rates of maturation, cleavage, and blastocyst rates, as compared with those from SF, whereas there were no significant differences in the cell number of blastocysts between SF and MF (32 v. 34 cells, respectively). When oocytes were denuded before IVM culture, rates of oocyte maturation (37.6% in SF and 50.8% in MF), and blastocyst formation (2.7% in SF and 27.3% in MF) were significantly lower than controls (51.2% in SF and 76% in MF; 25.8% in SF and 48.5% in MF, respectively). When oocytes were denuded 20 h after the start of IVM, oocyte maturation rates were significantly increased (64.1% in SF and 82.5% in MF) as compared with controls, whereas no significant differences were observed in cleavage and blastocyst formation rates in comparison with controls. These results conclude that removing cumulus cells from oocyte-cumulus complexes 20 h after the start of IVM improves the meiotic competence of oocytes derived from both SF and MF, without any reduction of developmental competence of the oocytes following parthenogenetical activation.

Abstract
Background Comprehensive genomic sequencing (CGS) has the potential to revolutionize precision medicine for cancer patients across the globe. However, to date large-scale genomic sequencing of cancer patients has been limited to Western populations. In order to understand possible ethnic and geographic differences and to explore the broader application of CGS to other populations, we sequenced a panel of 415 important cancer genes to characterize clinically actionable genomic driver events in 201 Japanese patients with colorectal cancer (CRC). Methods Using next-generation sequencing methods, we examined all exons of 415 known cancer genes in Japanese CRC patients (n = 201) and evaluated for concordance among independent data obtained from US patients with CRC (n = 108) and from The Cancer Genome Atlas-CRC whole exome sequencing (WES) database (n = 224). Mutation data from non-hypermutated Japanese CRC patients were extracted and clustered by gene mutation patterns. Two different sets of genes from the 415-gene panel were used for clustering: 61 genes with frequent alteration in CRC and 26 genes that are clinically actionable in CRC. Results The 415-gene panel is able to identify all of the critical mutations in tumor samples as well as WES, including identifying hypermutated tumors. Although the overall mutation spectrum of the Japanese patients is similar to that of the Western population, we found significant differences in the frequencies of mutations in ERBB2 and BRAF. We show that the 415-gene panel identifies a number of clinically actionable mutations in KRAS, NRAS, and BRAF that are not detected by hot-spot testing. We also discovered that 26% of cases have mutations in genes involved in DNA double-strand break repair pathway. Unsupervised clustering revealed that a panel of 26 genes can be used to classify the patients into eight different categories, each of which can optimally be treated with a particular combination therapy. Conclusions Use of a panel of 415 genes can reliably identify all of the critical mutations in CRC patients and this information of CGS can be used to determine the most optimal treatment for patients of all ethnicities.

Abstract
Background Nilotinib inhibits the tyrosine kinase activities of ABL1/BCR-ABL1, KIT, and platelet-derived growth factor receptors (PDGFRs). The results of a phase III clinical trial indicated that nilotinib could not be recommended for broad use as first-line therapy for gastrointestinal stromal tumor (GIST). However, some clinical studies have reported the effectiveness of nilotinib. We report here the cases of two patients who underwent surgical resections of nilotinib-resistant lesions after long-term nilotinib administration. Case presentation Two Japanese female patients, aged 66 and 70 years, experienced peritoneal recurrence of intestinal GIST several years after surgery. Both were registered in the ENESTg1 trial and received nilotinib therapy. Although they continued nilotinib administration with a partial response according to the protocol, nilotinib-resistant lesions, which were diagnosed as focally progressive disease, developed and complete surgical resection was performed. Pathological examination revealed that the tumors were composed of viable KIT-positive spindle cells, and the recurrent tumors were diagnosed as nilotinib-resistant GIST. In gene mutation analysis, a secondary KIT gene mutation was detected in one case. Both patients have survived more than 5 years after the first surgery. Conclusions Of patients who were registered in this trial, we have encountered two patients with long-term effects after nilotinib administration. Moreover, secondary mutations in the KIT gene, similar to those involved in resistance to imatinib, might be involved in resistance to nilotinib.

Abstract
BACKGROUND Severe blunt hepatic injury is a major cause of morbidity and mortality in pediatric patients. Damage control (DC) surgery has been reported to be useful in severely compromised children with hepatic injury. We applied such a technique in the treatment of a case of hemodynamically unstable grade IV blunt hepatic injury in an eight-year-old girl. This case is the first to use multimodal approaches including perihepatic packing, temporary closure of the abdominal wall with a plastic sheet, transarterial embolization (TAE), and planned delayed anatomical hepatic resection in a child. CASE PRESENTATION An eight-year-old girl was run over by a motor vehicle and transferred to the emergency department of the local hospital. Her diagnoses were severe blunt hepatic injury (grade IV) with left femoral trochanteric fracture. No other organ injuries were observed. Because her hemodynamic state was stable under aggressive fluid resuscitation, she was transferred to our hospital for surgical management. On arrival at our institution about 4 h after the injury, her hemodynamic condition became unstable. Abdominal compartment syndrome also became apparent. Because her condition had deteriorated and the lethal triad of low BT, coagulopathy, and acidosis was observed, a DC treatment strategy was selected. First, emergent laparotomy was performed for gauze-packing hemostasis to control intractable bleeding from the liver bed, and the abdomen was temporarily closed with a plastic sheet with continuous negative pressure aspiration. Transarterial embolization of the posterior branch of the right hepatic artery was then carried out immediately after the operation. The lacerated right lobe of the liver was safely resected in a stable hemodynamic condition 2 days after the initial operation. Bleeding from the liver bed ceased without further need of hemostasis. She was transferred to the local hospital without any surgical complications on day 42 after admission. She had returned to her normal life by 3 months after the injury. CONCLUSION The DC strategy was found to be effective even in a pediatric patient with hemodynamically unstable severe blunt hepatic injury. The presence of the deadly triad (hypothermia, coagulopathy, and acidosis) and abdominal compartment syndrome was an indication for DC surgery.

Abstract
Background Meigs’ syndrome is defined as the co-existence of benign ovarian fibroma or fibroma-like tumor, ascites, and pleural effusion. In contrast, pseudo-Meigs’ syndrome is defined as the co-existence of other ovarian or pelvic tumors, ascites, and pleural effusion. In Meigs’ and pseudo-Meigs’ syndromes, ascites and pleural effusion resolve promptly after the complete resection of the ovarian or pelvic tumor(s). Secondary ovarian tumors from colorectal gastrointestinal metastases rarely cause pseudo-Meigs’ syndrome; only 11 cases of pseudo-Meigs’ syndrome secondary to colorectal cancers have been reported in the literature. Therefore, the prognosis and etiology of pseudo-Meigs’ syndrome caused by ovarian metastasis from colorectal cancers remain unclear. Case presentation We report here a rare case of pseudo-Meigs’ syndrome caused by ovarian metastases from sigmoid colon cancer with long-term survival. A 47-year-old woman presented with abdominal distention of 1-month duration. She developed acute dyspnea 2 weeks after the initial presentation. Colonoscopy and computed tomography revealed sigmoid colon cancer with an ovarian metastasis, along with massive ascites and bilateral pleural effusion. Emergency operation, including bilateral oophorectomy and sigmoidectomy, was performed. Subsequently, ascites and bilateral pleural effusion resolved rapidly. Curative hepatic resection was performed for liver metastases 29 months after the first operation, and as of this writing, the patient is alive with no evidence of a disease 78 months after the first operation. In general, colorectal cancer with ovarian metastasis is hard to cure, and long-term survival in patients with colorectal cancer with pseudo-Meigs’ syndrome is rare. Our experience suggests that curative resection for pseudo-Meigs’ syndrome caused by ovarian metastasis from colorectal cancer may offer long-term survival. Conclusions Our experience suggests that pseudo-Meigs’ syndrome can occur in a patient with colorectal cancer after metastasis to the ovaries, causing massive ascites and pleural effusion. Aggressive treatment, including R0 resection, for this disease if allowed by the patient’s general condition may offer long-term survival.

Abstract
We report a case of panitumumab-resistant rectal cancer with HER2 gene amplification detected by CancerPlex®. A 51- year-old man was diagnosed with an obstructive rectal cancer having lung and adrenal metastases. He underwent the Hartmann 's operation, and KRAS mutations were not detected. After the surgery, 3 courses of CapeOx plus bevacizumab were administered as first-line chemotherapy; however, the lung and adrenal metastases progressed. Subsequently, 24 courses of IRIS/panitumumab was administered as second-line chemotherapy, and the metastases slowly progressed. Six courses of regorafenib were administered as third-line chemotherapy followed by a course of TAS-102 as fourth-line chemotherapy. Subsequently, a left femoral head metastasis and cerebellar metastases were detected. The patient received best supportive care including palliative femoral head replacement and stereotactic irradiation for the cerebellar metastases, and he died of cancer 3 years 5 months after the primary surgery. The comprehensive genomic analysis focusing on 413 cancer-related genes with CancerPlex®revealed that EGFR, BRAF, KRAS, NRAS, and HRAS had no mutations; however, ERBB2 amplification was detected. Furthermore, immunohistochemical staining revealed overexpression of HER2 protein in both the primary and bone metastatictumor. HER2 and EGFR independently promote the RAS-RAF-MAPK pathway. In the present case, the efficacy of anti-EGFR therapy may be attenuated because of ERBB2 amplification in the metastatic tumor.

Abstract
A 63-year-old man with epigastralgia was referred to our hospital and diagnosed with simultaneous multiple gastric cancers. One lesion was type 2 advanced and the other was type 0- II c early gastric cancer. CT examination revealed 4 regional lymph node metastases. Neoadjuvant chemotherapy(NAC)with docetaxel/CDDP/S-1was administered. After 2 courses of NAC, total gastrectomy with D2(-No. 10), lymphadenectomy was performed. The pathological response to NAC was judged to be Grade 3 for advanced gastric cancer and Grade 0 for early gastric cancer. The patient is alive with no evidence of disease during the 10 months after the operation.

Abstract
A46 -year-old male presented with bloody stool and a descending colon tumor, as identified using colon fiberscopy. The patient did not complain of any remarkable abdominal symptoms. Computed tomography revealed descending colon tumor intussusception. We performed partial resection of the descending colon and D2 lymphadenectomy without intraoperative reduction. The descending colon was barely attached to the retroperitoneum and was mobile. The underlying tumor was type 1 and measured 8.3×5.8 cm. The pathology report indicated a mucinous adenocarcinoma with extension through the submucosa into the subserosa, and metastasis in 6 nearby lymph nodes(n2). Intussusception is relatively rare in adults, particularly in portions of the colon fixed to the retroperitoneum, such as the descending colon. In contrast to previous reports of descending colon intussusception caused by age-related tissue dysfunction, we report our experience with a young patient and present the results obtained.

Abstract
A 58-year-old man was admitted with the complaint of bloody stools. Colonoscopy and computed tomography revealed a rectal cancer with a liver metastasis and multiple lung metastases. After administering a regimen comprising 3 courses of XELOX plus bevacizumab chemotherapy, the sizes of the primary and metastatic lesions decreased remarkably. Abdominoperineal resection was performed for local control of the cancer; the specimen from the initial tumor was found to be KRAS wild type. After 14 courses of XELOX chemotherapy, brain metastases were detected. Although 3 courses of IRIS plus panitumumab were administered, the liver, lung, and brain metastases spread rapidly. A comprehensive genomic analysis focused on cancer-related genes with CancerPlex®found a mutation of the BRAF gene(I326V). BRAF is a downstream molecule of KRAS in the RAS-RAF-MAPK pathway. Therefore, this mutation of the BRAF gene has the possibility of causing resistance against panitumumab that was found in this case. Furthermore, we expect that the systematic analysis of oncogene and suppressor oncogenes will enable us to choose the optimal regimen of chemotherapy or molecular targeting therapy for each patient with colorectal cancer.

Abstract
A 64-year-old woman diagnosed with duodenal adenocarcinoma with duodenal stenosis and obstructive jaundice was referred to our hospital. Computed tomography revealed a tumor measuring 9×6 cm in the second portion of the duodenum that had invaded the liver(S6)and head of the pancreas. After percutaneous transhepatic biliary drainage for obstructive jaundice, the patient underwent subtotal stomach-preserving pancreaticoduodenectomy, partial resection of the liver(S6), and partial resection of the colon. Histologic examination showed the primary tumor to be moderately and poorly differentiated adenocarcinoma with hepatic and pancreatic invasion; lymph node metastasis was not found. The patient received S-1 for 1 year and remains alive and well with no evidence of disease 15 months after resection.

Abstract
Although ductal carcinoma in situ(DCIS)is generally cured by surgical resection, it has been suggested that resection is over-treatment for some patients with DCIS. The aim of this study was to reconsider operative indications for patients with DCIS by examining clinicopathological features of 23 patients who underwent surgical resection for DCIS in our institute over a single year. Postoperative histological examination revealed that there were Luminal and HER2-positive subtypes, but no triple negative cancers. We found coincidental invasive ductal carcinoma(IDC)in 5 patients, and in all 5 the tumor size exceeded 60 mm. There was no coincidence of IDC in patients with a Ki-67 index ≤5%. Positive surgical margins were observed in 7 patients, all of which were histologically diagnosed as DCIS. Only 1 of the 7 patients underwent additional surgical resection; the 6 remaining patients, including 2 patients who received no treatment, did not undergo additional resection. All patients including those with positive surgical margins have had a 5-year relapse-free survival. Our findings imply that the subgroup of DCIS patients without IDC could be followed up without surgery.

Abstract
Recently, targeted drugs have been developed for the treatment of colorectal cancer(CRC). Among targets, it is well known that KRAS mutations are associated with resistance to epidermal growth factor receptor(EGFR)monoclonal antibodies. However, response rates using anti-EGFR monotherapy for CRC were less than 20-30% in previous clinical studies. Thus, because the RAS/MAP2K/MAPK and PI3K/AKT pathways are associated with CRC resistance to chemotherapy, we analyzed gene mutations in Stage IV CRC patients using a genomic test(CancerPlex®). Medical records were reviewed for 112 patients who received treatment for CRC between 2007 and 2015 in Niigata University Medical and Dental Hospital or Niigata Cancer Center Hospital. There were 66 male and 46 female patients, and their median age was 62.5(range, 30-86) years. Cluster analyses were performed in 110 non-hypermutated Japanese CRC patients using Euclidean distance and Ward's clustering method, and 6 typical groups were identified. Among these, patients with all wild-type actionable genes benefited from anti-EGFR therapies. The expense of targeted drugs warrants consideration of cost-effectiveness during treatment decision-making for advanced CRC patients. To this end, based on the genetic information on CRC, it is possible to develop precision medicine using CancerPlex®.

Abstract
A 57-year-old man with advanced gastric cancer and multiple liver metastases was referred to our hospital. He underwent a palliative gastrectomy to treat hemorrhage, and S-1 and cisplatin therapy was administered. After 7 courses of chemotherapy, a new liver metastatic lesion and a tumor thrombus in the right portal vein appeared. Moreover, the serum level of ammonia was elevated(296 mg/dL)following a consciousness disorder. Enhanced CT revealed an inferior mesenteric vein to left renal vein shunt, which led to the diagnosis of portal systemic encephalopathy due to portosystemic shunt. Percutaneous transvenous coil embolization was performed. The serum ammonia level decreased, and the encephalopathy disappeared. As a result, he was able to continue chemotherapy.

Abstract
We report a case of advanced gastric cancer(AGC)that was resected for rebleeding after palliative radiotherapy for hemostasis. A 74-year-old man with Stage IV gastric cancer received chemotherapy and achieved stable disease. After 23 months, he experienced continuous bleeding from the tumor due to regrowth. Palliative radiotherapy was conducted to control the bleeding, and the tumor successfully achieved hemostasis. However, 6 weeks later, the patient experienced rebleeding and developed hemostatic shock. We then performed a successful emergency gastrectomy. Bleeding negatively affects quality of life in patients with AGC and is potentially lethal. Although palliative radiotherapy for bleeding of gastric cancer is a safe and useful treatment within a short time frame in cases of rebleeding, emergency gastrectomy may be necessary. Therefore, when we select this treatment, the possibility of subsequent surgical treatment must be considered.

Abstract
A 77-year-old woman with rectal cancer and synchronous liver metastasis underwent a Hartmann operation with D3 lymph node dissection in June 2014. mFOLFOX6 plus bevacizumab(bev)was then administered to treat the liver metastasis.In February 2015, multiple liver metastases were detected and the regimen was changed to FOLFIRI plus bev.After 3 courses, peritonitis due to intestinal perforation around the descending colostomy occurred, and an emergency operation(partial resection of the descending colon and transverse colostomy)was performed.FOLFIRI was then administered from 2 months after the operation.After 3 courses of this regimen, a CT scan showed progression of the hepatic metastases.The regimen was therefore changed to mFOLFOX6.Five months later, another CT scan showed an intestinal perforation of the transverse colostomy at the abdominal wall, and an emergency cecostomy was performed.At this stage, chemotherapy was ceased.This case highlights the risk of intestinal perforation during chemotherapy, regardless of the use of bev.

Abstract
A 66-year-old woman with pancreatic cancer underwent resection of the pancreatic body and tail. Thirty-seven months after the initial surgery, a tumor was found in S4 of the right lung, for which resection of the middle lobe of the lung was performed. A diagnosis of lung metastasis originating from pancreatic cancer was confirmed based on histological and immunohistopathological assessments. Sixty-seven months after the initial surgery, despite the gemcitabine-based adjuvant chemotherapy, a tumor was detected in S3 of the left lung, for which partial lung resection was performed. Similar to the previous diagnosis, the tumor was diagnosed as lung metastasis of pancreatic cancer on the basis of the pathological findings. After the third operation, despite gemcitabine and S-1 chemotherapy, widespread pulmonary metastasis developed. One hundred and thirty months after the initial surgery, the patient died of respiratory failure due to carcinomatous pleurisy.

Abstract
A 77-year-old woman presented with a high fever. She had a history of resection of the extrahepatic bile duct, cholecystectomy, and hepaticojejunostomy for a congenital choledochal cyst, 23 years previously. Computed tomography showed a tumor measuring 90mm behind the head of the pancreas. This tumor appeared to invade the duodenum and pancreas, although swollen lymph nodes and distant metastasis were not detected. The patient was diagnosed with a carcinoma arising from the intrapancreatic remnant bile duct. A subtotal stomach-preserving pancreaticoduodenectomy and regional lymphadenectomy were performed. The patient remains alive and well with no evidence of disease 11 months after resection.

Abstract
A 78-year-old man with jaundice was diagnosed with perihilar cholangiocarcinoma(Bismuth type I ). After endoscopic biliary drainage for jaundice, a subtotal stomach-preserving pancreaticoduodenectomy was performed. Histologic examination and immunohistochemical staining with chromogranin A, synaptophysin, and CD56 resulted in a diagnosis of small cell carcinoma. Of the 18 dissected lymph nodes, 8 nodes contained a metastatic tumor. Left supraclavicular and paraaortic lymph node metastases were detected by computed tomography 5 months after the resection. He received cisplatin plus irinotecan chemotherapy, and after 2 courses of the chemotherapy, both metastatic lesions were reduced in size. He remains alive and well with no evidence of progressive disease after 6 courses of chemotherapy.

Abstract
We report here a case of long-term survival with repeated peritoneal recurrences after resection of perforated sigmoid colon cancer. A 65-year-old man presented with diarrhea and abdominal pain. Computed tomography(CT)revealed diffuse peritonitis caused by perforated sigmoid colon cancer. We performed sigmoidectomy with D2 lymphadenectomy and descending colostomy. Postoperatively, S-1 was administered for 12 months as adjuvant chemotherapy. CT showed peritoneal nodules 56 months after the surgery. After 10 courses of mFOLFOX6 plus bevacizumab, the tumors decreased in size (reduction rate of 34.4%; a partial response). Subsequently, 3 peritoneal nodules were resected with curative intent. Another peritoneal nodule was detected 57 months after the second surgery. After 3 courses of XELOX plus bevacizumab, the nodule decreased in size(reduction rate of 69.0%; a partial response). The nodule was resected with a curative intent. At the last follow-up 135 months after the first surgery, the patient remains alive with no evidence of disease.

Abstract
RAS mutation is an established predictive biomarker of resistance to anti-epidermal growth factor receptor(EGFR)therapy in metastatic colorectal cancer. In addition, previous studies identified mutations in ERBB2, FGFR1, PDGFRA, BRAF, MAP2K1, PTEN, and PIK3CA as potential mechanisms of resistance to anti-EGFR therapy. Testing for these mutations might be necessary to determine eligibility for anti-EGFR therapy in patients with metastatic colorectal cancer. CancerPlex®is a nextgeneration sequencer for 413 cancer genes. An analysis panel includes genes that may be associated with resistance to anti- EGFR therapy. A 65-year-old man with unresectable rectal cancer, multiple lung metastases, and a bulky liver metastasis was evaluated for expression of genes associated with resistance to anti-EGFR. The analysis found that all genes indicating resistance were wild-type genes. Cetuximab monotherapy was administered after rectal resection, with dramatic shrinkage of the metastatic tumors. A more accurate selection of patients according to tumor genetic status using CancerPlex®might improve the risk-benefit profile of anti-EGFR therapy.

Abstract
INTRODUCTION The elucidation of the clinical impact of comorbidities is important to optimize the treatment and follow-up strategy in oesophageal cancer. We aimed to clarify the surgical and long-term outcomes following oesophagectomy in oesophageal cancer patients with comorbidity. METHODS A total of 658 consecutive patients who underwent oesophagectomy for oesophageal cancer between 1985 and 2008 at our institution were enrolled. Based on the criteria of comorbidity as we defined it, we retrospectively reviewed and compared the surgical outcomes and survival between the comorbid (n = 251) and non-comorbid group (n = 407). RESULTS Postoperative morbidity and mortality were not significantly different between the two groups. The 5-year overall survival rate of the comorbid group was significantly lower (39.3% vs. 45.2%, adjusted HR = 1.31, 95% CI: 1.07-1.62) but the 5-year disease-specific survival rate was not significantly different between the comorbid and non-comorbid groups (53.9% vs. 53.1%, adjusted HR = 1.11, 95% CI: 0.86-1.42). The 5-year incidence rate of death from other diseases in the comorbid group was significantly higher than that in the non-comorbid group (26.7% vs. 14.8%, P < 0.01). The leading cause of death from other diseases was pneumonia. CONCLUSIONS Oesophagectomy in oesophageal cancer patients with comorbidity can be safely performed. However, the overall survival after oesophagectomy in these patients was unfavorable because of the high incidence of death from other diseases, especially pneumonia.

Abstract
BACKGROUND Prognoses vary substantially among patients with advanced gastric cancer following curative surgery. The aim of the current study was to develop and verify the validity of a novel nomogram that predicts the probability of 5-year relapse-free survival (RFS) in patients who underwent curative resection for stage II/III gastric cancer. MATERIALS AND METHODS A nomogram to predict 5-year RFS following surgical resection of gastric cancer was constructed based on the data of patients who underwent surgery for primary gastric carcinoma at three institutions in Japan in January 2001-December 2006. Multivariate analysis using a Cox proportional hazards regression model was performed, and the nomogram's predictive accuracy (discrimination) and the agreement between observed outcomes and predictions (calibration) were evaluated by internal validation. RESULTS Multivariate analyses revealed that age at operation, depth of tumor, tumor location, lymph node classification, and presence of combined resection were significant prognostic factors for RFS. In the internal validation, discrimination of the developed nomogram for 5-year RFS was superior to that of the American Joint Committee on Cancer TNM classification (concordance indices of 0.80 versus 0.67; P < 0.001). Moreover, calibration appeared to be accurate. Based on these results, we have created free software to more easily predict 5-year RFS. CONCLUSION We developed and validated a nomogram to predict 5-year RFS after curative surgery for stage II/III gastric cancer. This tool will be useful for the assessing a patient's individual recurrence risk when considering additional therapy in clinical practice.

Abstract
In this study, Takahashi et al. investigated the role of chromokinesin KIF4A in condensin complexes. They found that KIF4A associates with condensin I but not with condensin II during mitosis, providing new insight into the regulation of condensin I and mitotic chromsome organization. The chromokinesin KIF4A has been implicated in shaping mitotic chromosomes, but its functional relationship to condensin complexes remains controversial. Here, we found that, in mitosis, KIF4A associates with condensin I but not with condensin II. Mutational analyses indicated that the enrichment of condensin I to chromosomal axes depends on its association with KIF4A in a way that likely involves its motor activity. Remarkably, this interaction is required for condensin I to confer physiological properties to chromosomes. These observations provide an insight into how condensin I is enriched at chromosomal axes and underscore the significance of axial structure in organizing mitotic chromosomes.

Abstract
A 62-year-old man with abdominal pain and lumbago was admitted to our hospital. Blood examination revealed renal insufficiency, and CT revealed retroperitoneal fibrosis causing bilateral hydrocele and ureteral compression. A colonoscopy was performed to rule out secondary retroperitoneal fibrosis due to malignancies, and this imaging revealed an ascending colon cancer. Laparoscopic right hemicolectomy with lymphadenectomy and retroperitoneal biopsy were performed. The retroperitoneum was filled with hard, white fibrous tissue, which made it difficult to mobilize the right mesocolon from the retroperitoneum. Devascularization performed before mobilization allowed for a safe and oncologically feasible procedure. Histologically, there were no malignant cells in the retroperitoneal tissue. The patient has been without colon cancer reoccurrence for 4 years. When the surgical challenges that distinguish these patients from ordinary cases are recognized preoperatively, laparoscopic colectomy may be a feasible option for patients with colorectal cancer with idiopathic retroperitoneal fibrosis.

Abstract
Based on research carried out over the last decade, it has become increasingly evident that bile acids act not only as detergents, but also as important signaling molecules that exert various biological effects via activation of specific nuclear receptors and cell signaling pathways. Bile acids also regulate the expression of numerous genes encoding enzymes and proteins involved in the synthesis and metabolism of bile acids, glucose, fatty acids, and lipoproteins, as well as energy metabolism. Receptors activated by bile acids include, farnesoid X receptor α, pregnane X receptor, vitamin D receptor, and G protein-coupled receptors, TGR5, muscarinic receptor 2, and sphingosine-1-phosphate receptor (S1PR)2. The ligand of S1PR2, sphingosine-1-phosphate (S1P), is a bioactive lipid mediator that regulates various physiological and pathophysiological cellular processes. We have recently reported that conjugated bile acids, via S1PR2, activate and upregulate nuclear sphingosine kinase 2, increase nuclear S1P, and induce genes encoding enzymes and transporters involved in lipid and sterol metabolism in the liver. Here, we discuss the role of bile acids and S1P signaling in the regulation of hepatic lipid metabolism and in hepatobiliary diseases.

Abstract
Inflammation is a central process in several disorders and contributes to cancer progression. Inflammation involves a complex cascade of pro-inflammatory and anti-inflammatory signaling events with protein and lipid mediators. Recent advances in lipid detection have revealed the importance of lipid mediators in inflammation. Omega three polyunsaturated fatty acids (ω-3 PUFA) are found naturally in fish oil and have been extensively studied in multiple inflammatory diseases with improved outcomes. Resolvins are thought to be the active metabolites of ω-3 PUFA, and are responsible for facilitating the resolving phase of acute inflammation. Clinically, resolvins have been associated with resolution of acute kidney injury and acute lung injury, micro and macro vascular response to injury, and inhibition of microglia-activated inflammation in neurodegenerative disorders. In addition to inflammatory diseases, ω-3 PUFA and resolvins appear to modulate cancer progression. ω-3 PUFA intake has been associated with reduced inflammation in colorectal cancer, and favorable phenotype in breast cancer. Resolvins offer promising therapeutic potential as they may modulate inflammation with minimal side-effects, in contrast to currently available anti-inflammatory medications. This review describes the roles of ω-3 PUFA and resolvins in the inflammatory cascade, various inflammatory diseases, and specific cancers. Additionally, it will discuss the clinical therapeutic potential of resolvins as targets in inflammatory diseases and cancers.

Abstract
Background The presence of extramural tumor deposits without lymph node structure (EX) is an important prognostic factor for patients with colorectal cancer. However, the clinical significance of EX in the lateral pelvic lymph node area (LP-EX) remains unclear. This study aimed to determine the prognostic implications of LP-EX for patients with low rectal cancer. Methods This retrospective study involved 172 consecutive patients with stage 2 or 3 low rectal cancer who underwent curative surgery including lateral pelvic lymph node (LPLN) dissection. The patients were classified into the following three groups according to the metastatic status of the LPLN area: patients without metastasis (no-LP-M group), patients with lymph node metastasis (LP-LNM group), and patients with EX (LP-EX group). Potential prognostic factors of overall survival (OS) and relapse-free survival (RFS) were identified in uni- and multivariate analyses. Results Classification assigned 131 patients (76 %) to the no-LP-M group, 27 patients (16 %) to the LP-LNM group, and 14 patients (8 %) to the LP-EX group. The 5-year OS rate was 80.3 % in the no-LP-M group, 61.1 % in the LP-LNM group, and 34.9 % in the LP-EX group (P < 0.001). The corresponding 5-year RFS rates were 62.2, 33.8, and 14.3 %, respectively (P < 0.001). A multivariate Cox proportional hazards regression analysis showed that the presence of LP-EX was an independent prognostic factor for OS (P = 0.006) and RFS (P = 0.001). Conclusions The LP-EX classification is a useful pathologic parameter that can be used to stratify patients with metastasis in the LPLN area.

Abstract
p62/Sqstm1 is a multifunctional protein involved in cell survival, growth and death, that is degraded by autophagy. Amplification of the p62/Sqstm1 gene, and aberrant accumulation and phosphorylation of p62/Sqstm1, have been implicated in tumour development. Herein, we reveal the molecular mechanism of p62/Sqstm1-dependent malignant progression, and suggest that molecular targeting of p62/Sqstm1 represents a potential chemotherapeutic approach against hepatocellular carcinoma (HCC). Phosphorylation of p62/Sqstm1 at Ser349 directs glucose to the glucuronate pathway, and glutamine towards glutathione synthesis through activation of the transcription factor Nrf2. These changes provide HCC cells with tolerance to anti-cancer drugs and proliferation potency. Phosphorylated p62/Sqstm1 accumulates in tumour regions positive for hepatitis C virus (HCV). An inhibitor of phosphorylated p62-dependent Nrf2 activation suppresses the proliferation and anticancer agent tolerance of HCC. Our data indicate that this Nrf2 inhibitor could be used to make cancer cells less resistant to anticancer drugs, especially in HCV-positive HCC patients.

Abstract
BACKGROUND Complete immune tolerance is the chief goal in organ transplantation. This study aimed to evaluate patients who successfully withdrew from immunosuppressive (IS) agents after living donor liver transplantation (LDLT). MATERIALS AND METHODS A retrospective review of all adult LDLT from July 1999 to March 2012 was conducted. In patients who acquired immune tolerance after LDLT, their background and the course of surgical procedures were evaluated. RESULTS Of a total of 101 adult LDLT patients, 8 patients were completely free of IS agents. Six of these patients (75%) were female, and the median age at the time of transplantation was 56 years (range, 31-66 years). The primary disease causing liver failure was type C liver cirrhosis (50%), fulminant hepatitis (25%), type B liver cirrhosis (12%), and alcoholic liver cirrhosis (12%). The median Child-Pugh score and MELD score were 13 points (range, 8-15 points) and 19 points (range, 10-18 points), respectively. The living related donor was the recipient's child (75%), sibling (12%), or parent (12%). ABO compatibility was identical in 62%, compatible in 25%, and incompatible in 12%. CONCLUSIONS In this study, we evaluated the adult patients who successfully withdrew from IS agents after LDLT. In most cases, it took more than 5 years to reduce IS agents. Because monitoring of the serum transaminase level is not adequate to detect chronic liver fibrosis in immune tolerance cases, further study is required to find appropriate protocols for reducing IS agent use after LDLT.

Abstract
Endoscopic management of acute necrotic pancreatitis and walled off necrosis is less invasive than surgical treatment and has become the 1st choice for treating pancreatic necrosis and abscess. We treated a case of acute necrotic pancreatitis and walled off necrosis after auxiliary partial orthotopic living-donor liver transplantation (APOLT). A 24-year-old woman was admitted to our university hospital for removal of the internal biliary stent, which had already been placed endoscopically for the treatment of biliary stricture after APOLT. She had been treated for acute liver failure by APOLT 10 years before. After we removed the internal stent with the use of an endoscopic retrograde approach, she presented with severe abdominal pain and a high fever. Her diagnosis was severe acute pancreatitis after endoscopic retrograde cholangiography (ERC). Her symptoms worsened, and she had multiple organ failure. She was transferred to the intensive care unit (ICU). Immunosuppression was discontinued because infection treatment was necessary and the native liver had already recovered sufficiently. After she had been treated for 19 days in the ICU, she recovered from her multiple organ failure. However, abdominal computerized tomography demonstrated the formation of pancreatic walled off necrosis and an abscess on the 20th day after ERC. We performed endoscopic ultrasonography-guided abscess drainage and repeated endoscopic necrosectomy. The walled off necrosis diminished gradually in size, and the symptoms disappeared. The patient was discharged on the 87th day after ERC. This is the 1st report of a case of acute necrotic pancreatitis and walled off necrosis that was successfully treated by endoscopic management after APOLT.

Abstract
BACKGROUND Sphingosine-1-phosphate (S1P), a pleiotropic bioactive lipid mediator, has been implicated as a key regulatory molecule in cancer through its ability to promote cell proliferation, migration, angiogenesis, and lymphangiogenesis. Previous studies suggested that S1P produced by sphingosine kinase 1 (SphK1) in breast cancer plays important roles in progression of disease and metastasis. However, the associations between S1P and clinical parameters in human breast cancer have not been well investigated to date. MATERIALS AND METHODS We determined levels of S1P and other sphingolipids in breast cancer tissue by electrospray ionization-tandem mass spectrometry. Associations between S1P levels and clinicopathologic features of the tumors were analyzed. Expression of phospho-SphK1 (pSphK1) in breast cancer tissues was determined by immunohistochemical scoring. RESULTS Levels of S1P in breast cancer tissues were significantly higher in patients with high white blood cell count in the blood than those patients without. S1P levels were lower in patients with human epidermal growth factor receptor 2 overexpression and/or amplification than those patients without. Furthermore, cancer tissues with high pSphK1 expression showed significantly higher levels of S1P than cancer tissues without. Finally, patients with lymph node metastasis showed significantly higher levels of S1P in tumor tissues than the patients with negative nodes. CONCLUSIONS To our knowledge, this is the first study to demonstrate that high expression of pSphK1 is associated with higher levels of S1P, which in turn is associated with lymphatic metastasis in breast cancer.

Abstract
The tumor microenvironment is a determining factor for cancer biology and progression. Sphingosine-1-phosphate (S1P), produced by sphingosine kinases (SphKs), is a bioactive lipid mediator that regulates processes important for cancer progression. Despite its critical roles, the levels of S1P in interstitial fluid (IF), an important component of the tumor microenvironment, have never previously been measured due to a lack of efficient methods for collecting and quantifying IF. The purpose of this study is to clarify the levels of S1P in the IF from murine mammary glands and its tumors utilizing our novel methods. We developed an improved centrifugation method to collect IF. Sphingolipids in IF, blood, and tissue samples were measured by mass spectrometry. In mice with a deletion of SphK1, but not SphK2, levels of S1P in IF from the mammary glands were greatly attenuated. Levels of S1P in IF from mammary tumors were reduced when tumor growth was suppressed by oral administration of FTY720/fingolimod. Importantly, sphingosine, dihydro-sphingosine, and S1P levels, but not dihydro-S1P, were significantly higher in human breast tumor tissue IF than in the normal breast tissue IF. To our knowledge, this is the first reported S1P IF measurement in murine normal mammary glands and mammary tumors, as well as in human patients with breast cancer. S1P tumor IF measurement illuminates new aspects of the role of S1P in the tumor microenvironment.

Abstract
BACKGROUND Sphingolipids, including sphingosine-1-phosphate (S1P) and ceramide, have emerged as key regulatory molecules that control various aspects of cell growth and proliferation in cancer. Although important roles of sphingolipids in breast cancer progression have been reported in experimental models, their roles in human patients have yet to be determined. The aims of this study were to determine the levels of sphingolipids including S1P, ceramides, and other sphingolipids, in breast cancer and normal breast tissue and to compare the difference in levels of each sphingolipid between the two tissues. MATERIALS AND METHODS Tumor and noncancerous breast tissue were obtained from 12 patients with breast cancer. Sphingolipids including S1P, ceramides, and their metabolites of sphingosine, sphingomyelin, and monohexosylceramide were measured by liquid chromatography-electrospray ionization-tandem mass spectrometry. RESULTS The levels of S1P, ceramides, and other sphingolipids in the tumor were significantly higher than those in normal breast tissue. There was a relatively strong correlation in the levels of S1P between the tumor and those of normal breast tissue from the same person. On the other hand, there was no correlation in the levels of most of the ceramide species between the tumor and those of normal breast tissue from the same person. CONCLUSIONS To our knowledge, this is the first study to reveal that levels of sphingolipids in cancer tissue are generally higher than those of normal breast tissue in patients with breast cancer. The correlation of S1P levels in these tissues implicates the role of S1P in interaction between cancer and the tumor microenvironment.
