Abstract
BACKGROUND Peritoneal metastasis is a frequent cause of death in patients with gastric cancer. The aim of this study was to identify molecules responsible for mediating peritoneal metastasis of gastric cancer. METHODS Transcriptome and bioinformatics analyses were conducted to identify molecules associated with peritoneal metastasis. The therapeutic effects of intraperitoneally administered small interfering (si) RNA were evaluated using mouse xenograft models. Expression of mRNA and protein was determined in gastric tissues from patients with gastric cancer. RESULTS Synaptotagmin XIII (SYT13) was expressed at significantly higher levels in patients with peritoneal recurrence, but not in those with hepatic or distant lymph node recurrence. Inhibition of SYT13 expression in a gastric cancer cell line transfected with SYT13-specific siRNA (siSYT13) was associated with decreased invasion and migration ability of the cells, but not with proliferation and apoptosis. Intraperitoneal administration of siSYT13 significantly inhibited the growth of peritoneal nodules and prolonged survival in mice. In an analysis of 200 patients with gastric cancer, SYT13 expression in primary gastric cancer tissues was significantly greater in patients with peritoneal recurrence or metastasis. A high level of SYT13 expression in primary gastric cancer tissues was an independent risk factor for peritoneal recurrence. CONCLUSION SYT13 expression in gastric cancer is associated with perioneal metatases and is a potential target for treatment.

Abstract
The aim of the present study was to characterize the effect of long-term usage of dienogest, a fourth-generation progestin that possesses progestogen and anti-androgen activities, on the stockpile of oocytes and fertility after administration. Female ICR mice (100 days old) were divided into a dienogest group and a control group. The mice received 16 consecutive subcutaneous injections of 5 mg dienogest dissolved in corn oil or corn oil as a vehicle control every 4 days. The mice treated with dienogest had more total offspring and larger litter sizes after the final administration than the mice treated with the vehicle control. Greater numbers of primordial follicles were detected at both 4 and 80 days after the final administration. No significant differences were found in serum anti-Müllerian hormone concentrations at 4 and 80 days after the final dienogest administration. The ratio of primary to primordial follicles was decreased in 3-day-old newborn ovaries cultured for 4 days with dienogest (10-7, 10-6 and 10-5 mol/l) compared with ovaries cultured without dienogest. The results of the present study indicate that dienogest suppresses the activation of primordial follicles during its administration and preserves the primordial follicle stockpile and subsequent fertility in mice.

Abstract
A new classification of magnifying endoscopy with narrow band imaging (ME-NBI) for diagnosing and staging superficial esophageal squamous cell carcinoma (SESCC) was proposed by the Japan Esophageal Society in 2011. This study aimed to compare the new classification with the conventional classifications (Inoue's classification and Arima's classification). This was a prospective analysis of data from a single cancer center involving 151 consecutive patients with 156 SESCCs that were endoscopically or surgically resected. Initially, only ME-NBI images were selected and reviewed independently by three experienced endoscopists. White light imaging (WLI) was then evaluated separately after an interval. The diagnostic performance of each classification and interobserver agreement were assessed, and the WLI findings that affect the diagnosis by the new classification were identified. The specificity for classifying invasive depth as epithelium (EP)/lamina propria mucosae (LPM) confined was higher with the new classification than with Inoue's classification (0.512 vs. 0.349; P = 0.02) and Arima's classification (0.512 vs. 0.279; P < 0.01). However, the sensitivity was lower (0.902 vs. 1.000; P < 0.01) compared with Arima's classification. The concordance rates of three evaluators (κ values) were 0.52 for the new classification, 0.50 for Inoue's classification, and 0.23 for Arima's classification. On multivariate analysis, thickness on WLI independently affected the accuracy of diagnosis with the new classification (OR 3.23; 95%CI, 1.30-8.03). The new classification is superior to conventional classifications with respect to specificity for diagnosing SESCC with depth EP/LPM. Thickness on WLI was a factor negatively affecting the diagnostic performance of the new classification.

Abstract
Transient receptor potential cation channel subfamily M member 8 (TRPM8) is associated
with sensitivity to cold sensation in mammals. A previous study demonstrated that TRPM8
was overexpressed in the skin of ovariectomized (OVX) rats due to the loss of estrogen. In
the present study, we investigated whether estrogen replacement restricts overexpression
of the TRPM8 channel in the skin of OVX rats. We divided 15 Sprague Dawley rats into three
groups: a non-operated group (NON-OPE), an ovariectomy group (OVX), and a group subjected
to estrogen replacement during 4 weeks beginning 7 days after ovariectomy (OVX + E2). Five
weeks later, TRPM8 channel mRNA and protein in lumbar skin were quantified by real-time
RT-PCR, protein ELISA, and immunohistochemistry. The OVX + E2 group exhibited a trend for
decreased expression of the TRPM8 channel in the lumbar skin in comparison with the OVX
group, whereas ELISA data and immunohistochemistry data and immunohistochemistry graphs
relating to TRPM8 protein did not show any obvious differences between the OVX group and
the OVX + E2 group. Estrogen replacement may restrict the overexpression of TRPM8 in the
dermis of OVX rats.

Abstract
BACKGROUND Chronic endometritis (CE) is a continuous inflammation of uterine endometrium, and it is usually symptomless. As CE has been thought not to affect the reproductive status and general health of affected women, its significance has not been explored. However, recent studies have shown that CE is related with repeated implantation failures after in vitro fertilization-embryo transfer, unexplained infertility, and recurrent miscarriages. As decidua differentiates to support the implantation process and maintains the pregnancy, we hypothesized that CE may influence the process of decidualization. METHODS Seventeen patients were employed in the experiment involving culture of endometrial stromal cells (ESCs). After obtaining endometrial samples, ESCs were harvested and cultured for 13 days. The concentrations in culture media and the protein expressions in ESCs of prolactin (PRL) and insulin-like growth factor binding protein-1 (IGFBP-1), two well known decidualization markers used in a large number of in vitro models, were analyzed by ELISA and Western blotting, respectively, and the cell numbers were also counted. The mRNA levels of PRL and IGFBP-1 were tested by quantitative real time polymerase chain reaction (RT-PCR). Since sex hormone induce proliferation and differentiation to decidua via binding to the sex hormone receptors (ERα, ERβ, PRA, and PRB), their expression was assessed in another 17 patients' paraffin-embedded endometrial tissue specimens by immunohistochemistry and semi-quantified by H-score. RESULTS Increased cell numbers and reduced secretion of PRL and IGFBP-1 were detected by ELISA in the ESCs of CE patients after culture for 13 days compared with non-CE patients. The decreased protein expression of IGFBP-1 in ESCs of CE patients was detected by Western blotting. The decreased expression of PRL mRNA and IGFBP-1 mRNA were detected by RT-PCR. Increased expressions of ERα, ERβ, PRA, and PRB were observed in the stromal cells of CE patients in comparison to non-CE patients, whereas increased expressions of ERα and ERβ were detected in the glandular cells of CE. CONCLUSION Our data suggests that CE modifies decidualization of human ESC through untuning the function of sex steroid hormone receptor.

Abstract
Despite improvements in surgical techniques, perioperative management, and multidisciplinary therapy, treatment outcomes of patients with esophageal squamous cell carcinoma (ESCC) remain poor. Therefore, development of novel molecular biomarkers, which either predict patient survival or become therapeutic targets, is urgently required. In the present study, to facilitate early detection of ESCC and predict its clinical course, we investigated the relationship of the serum level of melanoma-associated antigen (MAGE)-D4 to patients' clinicopathological characteristics. Using quantitative real-time reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assays, we determined the levels of MAGE-D4 mRNA and protein in cell lysates and conditioned medium of cultures, respectively, of nine ESCC cell lines. Further, we determined MAGE-D4 levels in serum samples collected from 44 patients with ESCC who underwent radical esophagectomy without neoadjuvant therapy as well as from 40 healthy volunteers. Samples of conditioned medium and cell lysates contained comparable levels of MAGE-D4 that correlated closely with the levels of MAGE-D4 mRNA. Preoperative MAGE-D4 levels in the sera of 44 patients with ESCC, which varied from 0 to 2,354 pg/mL (314 ± 505 pg/mL, mean ± standard deviation), were significantly higher compared with those of healthy volunteers. By setting the cutoff at the highest value for healthy volunteers (50 pg/mL), the MAGE-D4-positive group of patients was more likely to have shorter disease-specific and disease-free survival compared with those of the MAGE-D4-negative group, although the differences were not statistically significant. Our results indicate that the elevation of preoperative serum MAGE-D4 levels in some patients with ESCC was possibly caused by excess production of MAGE-D4 by tumor cells followed by its release into the circulation. Clinical implications of serum MAGE-D4 levels should be validated in a large population of patients with ESCC.

Abstract
Historically, total pharyngolaryngectomy with total esophagectomy has been the standard radical surgical treatment for synchronous cancer of the thoracoabdominal esophagus and pharyngolaryngeal region, and for cancer of the cervical esophagus that has invaded as far as the thoracic esophagus. Although definitive chemoradiotherapy that enables preservation of the larynx has often been the first choice of treatment for cancers involving the cervical esophagus, total pharyngolaryngectomy with total esophagectomy is required as a salvage therapy for cases involving failure of complete remission or locoregional recurrence after chemoradiotherapy. However, salvage esophageal surgery after definitive high-dose chemoradiotherapy is generally associated with high morbidity and mortality. The aim of this study was to examine the short-term outcome of salvage total pharyngolaryngectomy with total esophagectomy. From 2001 to 2014, nine patients underwent salvage total pharyngolaryngectomy with total esophagectomy at the Department of Gastroenterological Surgery, Nagoya University. The mortality and morbidity rates were high at 22% and 89%, respectively. Four patients (44%) developed tracheal necrosis, which in two patients eventually led to lethal hemorrhage. Salvage total pharyngolaryngectomy with total esophagectomy is an uncommon and highly demanding surgical procedure that should be carefully planned and conducted in selected centers of excellence. Measures must be taken to preserve the tracheal blood supply, thus avoiding fatal complications.

Abstract
BACKGROUND We evaluated the efficacy and safety of S-1 plus oxaliplatin (SOX) as an alternative to cisplatin plus S-1 (CS) in first-line chemotherapy for advanced gastric cancer (AGC). PATIENTS AND METHODS In this randomized, open-label, multicenter phase III study, patients were randomly assigned to receive SOX (80-120 mg/day S-1 for 2 weeks with 100 mg/m(2) oxaliplatin on day 1, every 3 weeks) or CS (S-1 for 3 weeks with 60 mg/m(2) cisplatin on day 8, every 5 weeks). The primary end points were noninferiority in progression-free survival (PFS) and relative efficacy in overall survival (OS) for SOX using adjusted hazard ratios (HRs) with stratification factors; performance status and unresectable or recurrent (+adjuvant chemotherapy) disease. RESULTS Overall, 685 patients were randomized from January 2010 to October 2011. In per-protocol population, SOX (n = 318) was noninferior to CS (n = 324) in PFS [median, 5.5 versus 5.4 months; HR 1.004, 95% confidence interval (CI) 0.840-1.199; predefined noninferiority margin 1.30]. The median OS for SOX and CS were 14.1 and 13.1 months, respectively (HR 0.958 with 95% CI 0.803-1.142). In the intention-to-treat population (SOX, n = 339; CS, n = 337), the HRs in PFS and OS were 0.979 (95% CI 0.821-1.167) and 0.934 (95% CI 0.786-1.108), respectively. The most common ≥grade 3 adverse events (SOX versus CS) were neutropenia (19.5% versus 41.8%), anemia (15.1% versus 32.5%), hyponatremia (4.4% versus 13.4%), febrile neutropenia (0.9% versus 6.9%), and sensory neuropathy (4.7% versus 0%). CONCLUSION SOX is as effective as CS for AGC with favorable safety profile, therefore SOX can replace CS. CLINICAL TRIAL NUMBER JapicCTI-101021.

Abstract
BACKGROUND/AIMS This study evaluated the efficacy and safety of transnasal endoscopy (TNE) with flexible spectral imaging color enhancement (FICE) for detection of superficial cancer in the pharyngeal and esophageal regions for high-risk populations. METHODOLOGY Patients who previously had head and neck or esophageal squamous cell carcinoma were enrolled. Screening was conducted using TNE with conventional white-light endoscopy (WLE) followed by FICE chromoendoscopy. For observation of the pharyngeal region, the Valsalva maneuver was employed. RESULTS 99 patients were eligible. Six esophageal cancers were detected in four patients (4.0%). The sensitivity, specificity, and accuracy for the detection of cancer were 25.0% (95% CI, 3.4- 71.0), 97.8% (95% CI, 92.1-99.8), and 94.9 % (95% CI, 88.4-98.1), respectively for WLE; 100% (95% CI, 45.4%- 100%), 96.8% (95% CI, 90.7%-99.3%), and 96.9% (95% CI, 89.3%-99.1%), respectively for FICE chromoendoscopy. Pain in the nose and nasal hemorrhage were observed in 3 (3.0%) and 2 patients (2.0%), respectively. Following the Valsalva maneuver, endoscopic scores significantly increased from a mean of 1.1 (0.8-1.4) to 2.0 (1.3-2.6) (p<0.05). CONCLUSIONS TNE with the Valsalva maneuver is a promising screening method for the pharyngeal and esophageal regions. TNE with FICE chromoendoscopy for detecting pharyngeal and esophageal cancer was more sensitive than WLE.

Abstract
A prospective clinical study was conducted to evaluate the safety, feasibility, and efficacy of endoscopic ultrasound (EUS)-guided choledochoduodenostomy (CDS) with direct metallic stent placement using a prototype forward-viewing echoendoscope. The indication for EUS - CDS in this study was lower biliary obstruction only, and not failed endoscopic biliary drainage, because the aim was to evaluate EUS - CDS for first-line biliary drainage therapy. The technical and functional success rates were 94 % (17 /18) and 94 % (16 /17), respectively. Early complications (focal peritonitis) were encountered in two patients (11 %). No patients developed late complications. EUS - CDS with direct metallic stent placement using a forward-viewing echoendoscope was generally feasible and effective for malignant distal biliary tract obstruction. The forward-viewing echoendoscope was useful, especially for deploying the metallic stent.

Abstract
OBJECTIVE This study retrospectively evaluated the efficacy and toxicity of particle therapy using carbon ions or protons for primary sacral chordomas. METHODS We evaluated 23 patients with primary sacral chordoma treated with carbon ion therapy (CIT) or proton therapy (PT) between July 2005 and June 2011 at the Hyogo Ion Beam Medical Center, Hyogo, Japan. The median patient age was 72 years. 14 patients were treated with 70.4 Gy equivalents (GyE) in 16 fractions and 9 were treated with 70.4 GyE in 32 fractions. CIT was used for 16 patients, and PT was used for 7 patients. RESULTS The median follow-up period was 38 months. At 3 years, local control (LC), overall survival (OS) and progression-free survival (PFS) for all patients were 94%, 83% and 68%, respectively. The log-rank test revealed that male sex was significantly related to better PFS (p=0.029). No other factors, including dose fractionation and ion type, were significant for LC, OS or PFS. In nine patients, ≥ Grade 3 acute dermatitis was observed, and ≥ Grade 3 late toxicities were observed in nine patients. The 32-fraction protocol reduced severe toxicities in both the acute and late phases compared with the 16-fraction protocol. CONCLUSION Particle therapy for patients with sacral chordoma showed favourable LC and OS. Severe toxicities were successfully reduced by modifying the dose fractionation and treatment planning in the later treatment era. Thus, this therapeutic modality should be considered useful and safe. ADVANCES IN KNOWLEDGE This is the first study including both CIT and PT for sacral chordomas.

Abstract
To pursue an urgently needed treatment target for esophageal cancer (EC), we investigated the function of the recently discovered melanoma-associated antigen (MAGE)-D4 in squamous cell EC. MAGE-D4 messenger RNA (mRNA) expression was analyzed in nine EC cell lines using quantitative reverse transcription polymerase chain reaction. In 65 surgical specimens of squamous cell EC with no prior neoadjuvant therapy, MAGE-D4 mRNA expression in EC tissues and corresponding normal tissues was analyzed and compared, and evaluated in terms of clinicopathological factors. In representative cases, MAGE-D4 protein distribution was analyzed immunohistochemically. The heterogeneity of MAGE-D4 mRNA expression was confirmed in EC cell lines by quantitative reverse transcription polymerase chain reaction. In surgical specimens, MAGE-D4 mRNA expression was significantly higher in EC tissues than in corresponding normal tissues (P < 0.001). Patients with the highest MAGE-D4 mRNA expression in EC tissues (top quartile, n = 17) had significantly shorter overall survival than patients with low expression (2-year survival: 44% and 73%, respectively, P = 0.006). Univariate analysis identified age (≥65 years), lymphatic involvement, and high MAGE-D4 mRNA expression as significant prognostic factors; high MAGE-D4 mRNA expression was also an independent prognostic factor in multivariable analysis (hazard ratio: 2.194; P = 0.039) and was significantly associated with Brinkman index (P = 0.008) and preoperative carcinoembryonic antigen level (P = 0.002). Immunohistochemical MAGE-D4b expression was consistent with MAGE-D4 mRNA profiling. Our results suggest that MAGE-D4 overexpression influences tumor progression, and MADE-D4 can be a prognostic marker and a potential molecular target in squamous cell EC.

Abstract
Recently, ultrasound-guided percutaneous ethanol injection therapy (PEIT) has been widely performed in the treatment of hepatocellular carcinoma. Histopathologic examinations after the therapy have revealed that PEIT can destroy the tumor completely in most cases. Findings in imaging modalities and serum tumor marker levels have also shown a remarkable anticancer effect of this procedure. In addition, PEIT has achieved considerably high long-term survival rates. PEIT is a generally safe procedure and serious complications are rare. PEIT seems to be a valuable therapy and could even be an alternative to surgery in the treatment of hepatocellular carcinoma. This paper reviews the pertinent literature on this new therapy.

Abstract
BACKGROUND Metastasis to the pancreas (MP) is a rare entity that is difficult to identify by imaging alone. Few reports have described endoscopic ultrasound (EUS) and EUS-guided fine-needle aspiration (FNA) findings. Herein, we try to describe the EUS and EUS-FNA characteristics of MP. METHODS This retrospective study compared 28 patients with MP (13 males; mean age: 60.1 ± 12.6 years) and 60 control patients (30 males; 62.7 ± 11.5 years) with pancreatic ductal adenocarcinoma (PDAC). All lesions were characterized by EUS, and MP was diagnosed by EUS-FNA (n = 16), surgery (n = 6) or both (n = 6). RESULTS Multivariate logistic regression revealed that the presence of regular borders (p = 0.004; OR: 8.81, 95% CI: 1.97-39.4), the absence of retention cysts (p = 0.045; OR: 12.5, 95% CI: 1.06-147.0), and the absence of main pancreatic duct (MPD) dilation (p = 0.003; OR: 8.18, 95% CI: 2.04-32.8) were predictors of MP rather than PDAC. The EUS-FNA sampling adequacy was 95.4% (21/22), and the correct diagnosis was obtained in 95.2% (20/21) of cases when K-ras mutation analysis and/or immunostaining were added. CONCLUSION The presence of regular borders, the absence of retention cysts and the presence of nondilated MPD on EUS indicate MP rather than PDAC. This diagnosis can be accurately confirmed by EUS-FNA with immunostaining and/or K-ras analysis.

Abstract
BACKGROUND & AIMS The DNA/RNA editing enzyme activation-induced cytidine deaminase (AID) is mutagenic and has been implicated in human tumorigenesis. Helicobacter pylori infection of gastric epithelial cells leads to aberrant expression of AID and somatic gene mutations. We investigated whether AID induces genetic aberrations at specific chromosomal loci that encode tumor-related proteins in gastric epithelial cells. METHODS Human gastric epithelial cell lines that express activated AID and gastric cells from AID transgenic mice were examined for DNA copy number changes and nucleotide alterations. Copy number aberrations in stomach cells of H pylori-infected mice and gastric tissues (normal and tumor) from H pylori-positive patients were also analyzed. RESULTS In human gastric cells, aberrant AID activity induced copy number changes at various chromosomal loci. In AID-expressing cells and gastric mucosa of AID transgenic mice, point mutations and reductions in copy number were observed frequently in the tumor suppressor genes CDKN2A and CDKN2B. Oral infection of wild-type mice with H pylori reduced the copy number of the Cdkn2b-Cdkn2a locus, whereas no such changes were observed in the gastric mucosa of H pylori-infected AID-deficient mice. In human samples, the relative copy numbers of CDKN2A and CDKN2B were reduced in a subset of gastric cancer tissues compared with the surrounding noncancerous region. CONCLUSIONS H pylori infection leads to aberrant expression of AID and might be a mechanism of the accumulation of submicroscopic deletions and somatic mutations in gastric epithelial cells. AID-mediated genotoxic effects appear to occur frequently at the CDKN2b-CDKN2a locus and contribute to malignant transformation of the gastric mucosa.

Abstract
The predominant histopathologic feature of inflammatory bowel disease is the infiltration of acute and chronic inflammatory cells, including polymorphonuclear neutrophils, macrophages and lymphocytes, in the affected intestine. Helicobacter pylori is recognized as the most common cause of upper gastrointestinal lesions, and Helicobacter pylori-associated gastritis is characterized by increased numbers of acute and chronic inflammatory cells. The pathogenesis of inflammatory bowel disease or Helicobacter pylori-associated gastritis involves immunological abnormalities, including the deficient or excessive expression of cytokines. The chronic inflammatory process in patients with Crohn's disease may affect any part of the gastrointestinal tract, whereas ulcerative colitis affects mainly the colon and rectum. Here, we discuss abnormalities in the upper gastrointestinal tract in inflammatory bowel disease. Although the prevalence rate of Helicobacter pylori infection is low in Crohn's disease, these patients often have abnormalities in the upper gastrointestinal tract.

Abstract
BACKGROUND AND AIMS Although cyclosporin A has been reported to be effective in the treatment of severe ulcerative colitis, factors predicting its therapeutic efficacy remain unclear. Technical progress in endoscopic ultrasonography has improved visualisation of the structure of the colon wall. Here, to assess the value of endoscopic ultrasonography in predicting the response to cyclosporin A treatment, we evaluated the therapeutic effect of cyclosporin A by determining the pre- and post-cyclosporin A thickness of the mucosal layer in the rectum using endoscopic ultrasonography with an ultrasonic catheter probe. PATIENTS AND METHODS Fifteen ulcerative colitis patients who did not respond to high-doses of corticosteroids were treated with cyclosporin A by continuous intravenous infusion at 4mg/kg/day for 20 days. Before and 20 days after cyclosporin A therapy, clinical disease activity was assessed using clinical activity index scores. Colonoscopy and endoscopic ultrasonography were undertaken before and 20 days after cyclosporin A therapy. RESULTS Following treatment with cyclosporin A, nine patients showed a decrease in clinical activity index score by six points or more and were defined as responders, while the other six were defined as non-responders. Endoscopic ultrasonography measurement using an ultrasonic catheter probe showed that thickness of the rectal mucosal layer before cyclosporin A was significantly greater in responders than in non-responders (p<0.05). Further, thickness after cyclosporin A was statistically decreased (p<0.01) in the responders but not in the non-responders. CONCLUSIONS The ultrasonic catheter probe may represent a useful means of predicting and evaluating the efficacy of cyclosporin A treatment in severely ill ulcerative colitis patients.
