| 1 | Clinical utility of the platelet-lymphocyte ratio as a predictor of postoperative complications after radical gastrectomy for clinical T2-4 gastric cancer显示文摘AIM To identify simple and sensitive markers for postoperative complications after gastrectomy, the predictive values were compared among candidate preoperative factors. METHODS Three-hundred and twelve patients with previously untreated clinical T2-4 gastric cancer who underwent a D2 standard gastrectomy(distal gastrectomy or total gastrectomy) were included in the analysis.Correlations between 21 parameters that can be determined by preoperative routine blood tests and clinically relevant postoperative complications(grade Ⅱ or higher according to the Clavien-Dindo classification) were evaluated. The optimal cutoff values and clinical significance of the selected markers were further evaluated by subgroup analyses according to age, body mass index, operative procedure and clinical disease stage.RESULTS Sixty-six patients(21.1%) experienced grade Ⅱ or higher postoperative complications. The plateletlymphocyte ratio(PLR, total lymphocyte count/platelet count × 100) exhibited the highest area under the curve value(0.639) for predicting postoperative complications among the 21 parameters, and the optimal cutoff value was determined to be 0.71(sensitivity = 70%, specificity = 56%). In the univariate analysis, the odds ratio of a low PLR for the occurrence of postoperative complications was 2.94(95%CI: 1.66-5.35, P < 0.001), and a multivariate binomial logistic analysis involving other potential risk factors identified a low PLR as an independent risk factor for postoperative complications(OR = 3.32, 95%CI: 1.82-6.25, P < 0.001). In subgroups classified according to age, body mass index, operative procedure and clinical disease stage, the low PLR group exhibited an increased incidence of postoperative complications. CONCLUSION The preoperative PLR is a simple and useful predictor of complications after curative gastrectomy in patients with clinical T2-4 gastric cancer. | Kenichi Inaoka Mitsuro Kanda Hiroaki Uda Yuri Tanaka Chie Tanaka Daisuke Kobayashi Hideki Takami Naoki Iwata Masamichi Hayashi Yukiko Niwa Suguru Yamada Tsutomu Fujii Hiroyuki Sugimoto Kenta Murotani Michitaka Fujiwara Yasuhiro Kodera | 2017 | World Journal of Gastroenterology2017，23，14： | 13 |
| 2 | Can mosapride citrate reduce the volume of lavage solution for colonoscopy preparation?显示文摘AIM:To evaluate the possibility of reducing the volume of polyethylene glycol(PEG)-electrolyte solution using adjunctive mosapride citrate for colonoscopy preparation. METHODS:This was a single-center,prospective, randomized,investigator-blinded,non-inferiority study involving 252 patients of both sexes,aged from 20 to 80 years,scheduled for screening or diagnostic colonoscopy in our department.A total of 126 patients was randomized to receive 1.5 L PEG-electrolyte solution plus 15 mg of mosapride(1.5 L group),and 126 received 2 L PEG-electrolyte solution plus 15 mg of mosapride(2 L group).Patients completed a questionnaire on the acceptability and tolerability of the bowel preparation process.The efficacy of bowel preparation was assessed using a 5-point scale based on the Aronchick scale.The primary end point was adequate bowel preparation rates(score of excellent/good/fair) vs(poor/inadequate).Acceptability and tolerability,as well as disease detection,were secondary end points. RESULTS:A total of 244 patients was included in the analysis.There were no significant differences between the 2 L and 1.5 L groups in age,sex,body mass index, number of previous colonoscopies,and the preparation method used previously.The adequate bowel preparation rates were 88.5%in the 2 L group and 82.8%in the 1.5 L group[95%lower confidence limit(LCL)for the difference=-14.5%,non-inferiority P=0.019]in the right colon.In the left colon,the adequate bowel preparation rates were 89.3%in the 2 L group and 81.1%in the 1.5 L group(95%LCL=-17.0%,non-inferiority P=0.066).Compliance,defined as complete (100%)intake of the PEG solution,was significantly higher in the 1.5 L group than in the 2 L group(96.8% vs 85.7%,P=0.002).The proportion of abdominal distension(none/mild/moderate/severe)was significantly lower in the 1.5 L group than in the 2 L group (36/65/22/3 vs 58/48/18/2,P=0.040).Within the subgroup who had undergone colonoscopy previously, a significantly higher number of patients in the 1.5 L group than in the 2 L group felt that the current preparation was easier than the previous one(54.1%vs 28.0%,P=0.001).The disease detection rate was not significantly different between the two groups. CONCLUSION:Although the 1.5 L group had better acceptability and tolerability,15 mg of mosapride may be insufficient to compensate for a 0.5-L reduction of PEG solution. | Masahiro Tajika Yasumasa Niwa Vikram Bhatia Shinya Kondo Tsutomu Tanaka Nobumasa Mizuno Kazuo Hara Susumu Hijioka Hiroshi Imaoka Koji Komori Kenji Yamao | 2013 | World Journal of Gastroenterology2013，19，5： | 8 |
| 3 | Clinical relevance of fluorodeoxyglucose positron emission tomography/computed tomography and magnifying endoscopy with narrow band imaging in decision-making regarding the treatment strategy for esophageal squamous cell carcinoma显示文摘BACKGROUND Recent advances in endoscopic technology,especially magnifying endoscopy with narrow band imaging(ME-NBI)enable us to detect superficial esophageal squamous cell carcinoma(ESCC),but determining the appropriate method of resection,endoscopic resection(ER)vs surgical resection,is often challenging.Recently,several studies have reported that 18F-fluorodeoxyglucose positron emission tomography(FDG-PET)is a useful indicator for decision-making regarding treatment for superficial ESCC.Although,there are not enough reports on association between FDG-PET uptake and clinicopathological characteristics of superficial ESCC.And,there are not enough reports on evaluating the usefulness of combination of FDG-PET and ME-NBI for determining the treatment strategy for superficial ESCC.This study evaluated clinical relevance of FDG-PET and ME-NBI in decision-making regarding the treatment strategy for ESCC.AIM To investigate the association between FDG uptake and the clinicopathological characteristics of superficial ESCC and its usefulness of combination of FDG-PET and ME-NBI for determining the treatment strategy for superficial ESCC.METHODS A database of all patients with superficial ESCC who had undergone both MENBI and FDG-PET for pre-treatment staging at Aichi Cancer Center Hospital between January 2008 and November 2018 was retrospectively analyzed.FDG uptake was defined positive or negative whether the primary lesion was visualized or could be distinguished from the background,or not.The invasion depth of ESCC was classified according to the Japan Esophageal Society.Primary endpoint is to evaluate the association between FDG uptake and clinicopathological characteristics of superficial ESCC.Secondary endpoint is to investigate the efficacy of combination of FDG-PET and ME-NBI for determining the treatment strategy for superficial ESCC.RESULTS A total of 82 lesions in 82 patients were included.FDG-PET showed positive uptake in 29(35.4%)lesions.Univariate analysis showed that uptake of FDG-PET had significant correlations with circumferential extension(P=0.014),pathological depth of tumor invasion(P<0.001),infiltrative growth pattern(P<0.001),histological grade(P=0.002),vascular invasion(P=0.001),and lymphatic invasion(P<0.001).On multivariate analysis,only depth of tumor invasion was independently correlated with FDG-PET/computed tomography visibility(P=0.018).The sensitivity,specificity,positive predictive value(PPV),negative predictive value(NPV),and accuracy of Type B2 in ME-NBI for the invasion depth of T1a muscularis mucosae and T1b upper submucosal layer were 68.4%/79.4%/50.0%/89.3%/76.8%,respectively,and those of Type B3 for the depth of T1b middle and deeper submucosal layers(SM2 and SM3)were 46.7%/100%/100%/89.3%/90.2%,respectively.On the other hand,those of FDGPET for SM2 and SM3 were 93.3%/77.6%/48.2%/98.1%/80.5%,respectively,whereas,if the combination of positive FDG uptake and type B2 and B3 was defined as an indicator for radical esophagectomy or definitive chemoradiotherapy,the sensitivity,specificity,PPV,NPV,and accuracy were 78.3%/91.5%/78.3%/91.5%/87.8%,respectively.CONCLUSION FDG uptake was correlated with the invasion depth of superficial ESCC.Combined use of FDG-PET and ME-NBI,especially with the microvascular findings of Type B2 and B3,is useful to determine whether ER is indicated for the lesion. | Kazuhiro Toriyama Masahiro Tajika Tsutomu Tanaka Makoto Ishihara Yutaka Hirayama Sachiyo Onishi Nobumasa Mizuno Takamichi Kuwahara Nozomi Okuno Shinpei Matsumoto Eiichi Sasaki Tetsuya Abe Yasushi Yatabe Kazuo Hara Keitaro Matsuo Tsuneo Tamaki Yasumasa Niwa | 2019 | World Journal of Gastroenterology2019，25，46： | 7 |
| 4 | Association between TNF-a and IL-1β genotypes vs Helicobacter pylori infection in Indonesia显示文摘AIM:To investigate the correlation between the Helicobacter pylori(H.pylori)infection and host genetic background of healthy populations in Indonesia.METHODS:In March 2007,epidemiological studies were undertaken on the general population of a city in Indonesia(Mataram,Lombok).The participants included 107 men and 187 women,whose ages ranged from6 to 74 years old,with an average age of 34.0(±14.4)(±SD).The H.pylori of subject by UBT method determination,and through the polymerase chain reaction with confronting two-pair primers(PCR-CTPP)method parsing the single nucleotide polymorphism of interleukin(IL)-8,IL-4,IL-1β,CD14,tumor necrosis factor(TNF-a)and tyrosine-protein phosphates non-receptor type 11(PTPN11)genotypes.The experimental data were analyzed by the statistical software SAS.RESULTS:The H.pylori infection rates in the healthy Indonesian population studied were 8.4%for men and12.8%for women;no obvious differences were noted for H.pylori infection rates by sex or age.TC genotypes of IL-4,TC and CC genotypes of TNF-a,and GA genotypes of PTPN11,were higher in frequency.Both CC and TC genotype of TNF-a T-1031C loci featured higher expressions in the healthy Indonesian population Indonesia studied of(OR=1.99;95%CI:0.67-5.89)and(OR=1.66;95%CI:0.73-3.76),respectively.C allele of IL-1βT-31C gene locus was at a higher risk(OR=1.11;95%CI:0.70-1.73)of H.pylori infection,but no statistical significance was found in our study.CONCLUSION:We reveal that the association between the TNF-a and IL-1βgenotypes may be the susceptibility of H.pylori in the studied population. | Yang Zhao Jing-Wen Wang Tsutomu Tanaka Akihiro Hosono Ryosuke Ando Shinkan Tokudome Soeripto FX Ediati Triningsih Tegu Triono Suwignyo Sumoharjo EY Wenny Astuti Achwan Stephanus Gunawan Yu-Min Li | 2013 | World Journal of Gastroenterology2013，19，46： | 5 |

| 6 | Risk of ileal pouch neoplasms in patients with familial adenomatous polyposis显示文摘Restorative proctocolectomy is the most common surgical option for patients with familial adenomatous polyposis(FAP). However,adenomas may develop in the ileal pouch mucosa over time,and even carcinoma in the pouch has been reported. We therefore reviewed the prevalence,nature,and treatment of adenomas and carcinoma that develop after proctocolectomy in the ileal pouch mucosa in patients with FAP. In 25 reports that were reviewed,the incidence of adenomas in the ileal pouch varied from 6.7% to 73.9%. Several potential factors that favor the development of pouch polyposis have been investigated,but many remain controversial. Nevertheless,it seems certain that the age of the pouch is important. The risk appears to be 7%to 16% after 5 years,35% to 42% after 10 years,and75% after 15 years. On the other hand,only 21 cases of ileal pouch carcinoma have been recorded in the literature to date. The diagnosis of pouch carcinoma was made between 3 to 20 years(median,10 years) after pouch construction. Although the risk of malignant transformation in ileal pouches is probably low,it is not negligible,and the long-term risk cannot presently be well quantified. Regular endoscopic surveillance,especially using chromoendoscopy,is recommended. | Masahiro Tajika Yasumasa Niwa Vikram Bhatia Tsutomu Tanaka Makoto Ishihara Kenji Yamao | 2013 | World Journal of Gastroenterology2013，19，40： | 4 |

| 10 | Diagnostic utility of small-caliber and conventional endoscopes for gastric cancer and analysis of endoscopic false-negative gastric cancers显示文摘AIM: To analyze the diagnostic utility of a small-caliber endoscope(SC-E) and clinicopathological features of false-negative gastric cancers(FN-GCs). METHODS: A total of 21638 esophagogastroduodenoscopy(EGD) gastric cancer(GC) screening examinations were analyzed. Secondary endoscopic examinations(n = 3352) were excluded because most secondary examinations tended to be included in the conventional endoscopy(C-E) group. Detection rates of GCs and FN-GCs were compared between SC-E and C-E groups. FN-GC was defined as GC performed with EGD within the past 3 years without GC detection. Macroscopic types, histopathological characteristics and locations of FN-GCs were compared with firstly foundgastric cancers(FF-GCs) in detail. RESULTS: SC-E cases(n = 6657) and C-E cases(n = 11644), a total of 18301 cases, were analyzed. GCs were detected in 16(0.24%) SC-E cases and 40 C-E(0.34%) cases(P = 0.23) and there were 4 FN-GCs(0.06%) in SC-E and 13(0.11%) in C-E(P = 0.27), with no significant difference. FN-GCs/GCs ratio between SC-E and C-E groups was not significantly different(P = 0.75). The comparison of endoscopic macroscopic types of FN-GCs tended to be a less advanced type(P = 0.02). Histopathologically, 70.6% of FN-GCs were differentiated and 29.4% undifferentiated type. On the other hand, 43.0% of FF-GCs were differentiated and 53.8% undifferentiated type, so FN-GCs tended to be more differentiated type(P = 0.048). CONCLUSION: The diagnostic utility of SC-E for the detection of GCs and FN-GCs was not inferior to that of C-E. Careful observation for superficially depressed type lesions in the upper lesser curvature region is needed to decrease FN-GCs. | Hiromi Kataoka Kiyoshi Mizuno Noriyuki Hayashi Mamoru Tanaka Hirotaka Nishiwaki Masahide Ebi Tsutomu Mizoshita Yoshinori Mori Eiji Kubota Satoshi Tanida Takeshi Kamiya Takashi Joh | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，9： | 2 |

| 13 | Bone regeneration with osteogenic matrix cell sheet and tricalcium phosphate:An experimental study in sheep显示文摘AIM To determine the effects of a cell sheet created from sheep bone marrow and tricalcium phosphate(TCP) on osteogenesis.METHODS Bone marrow cells were harvested from a sheep and cultured in a minimal essential medium(MEM) containing ascorbic acid phosphate(AscP) and dexamethasone(Dex). After 2 wk, the formed osteogenic matrix cell sheet was lifted from the culture dish using a scraper. Additionally, harvested bone marrow cells were cultured in MEM only as a negative control group, and in MEM with AscP, Dex, and β-glycerophosphate as a positive control group. For in vitro evaluation, we measured the alkaline phosphatase(ALP) activity and osteocalcin(OC) content in the media of the cultured cells from each group. For in vivo analysis, a porous TCP ceramic was used as a scaffold. We prepared an experimental group comprising TCP scaffolds wrapped with the osteogenic matrix cell sheets and a control group consisting of the TCP scaffold only. The constructs wereimplanted subcutaneously into athymic rats and the cell donor sheep, and bone formation was confirmed by histology after 4 wk.RESULTS In the in vitro part, the mean ALP activity was 0.39 ± 0.03 mg/well in the negative control group, 0.67 ± 0.04 mg/well in the sheet group, and 0.65 ± 0.07 mg/well in the positive control group. The mean OC levels were 1.46 ± 0.33 ng/well in the negative control group, 3.92 ± 0.16 ng/well in the sheet group, and 4.4 ± 0.47 ng/well in the positive control group, respectively. The ALP activity and OC levels were significantly higher in the cell sheet and positive control groups than in the negative control group(P < 0.05). There was no significant difference in ALP activity or OC levels between the cell sheet group and the positive control group(P > 0.05). TCP constructs wrapped with cell sheets prior to implantation showed bone formation, in contrast to TCP scaffolds alone, which exhibited poor bone formation when implanted, in the subcutaneous layer both in athymic rats and in the sheep. CONCLUSION This technique for preparing highly osteoinductive TCP may promote regeneration in large bone defects. | Tsutomu Kira Manabu Akahane Shohei Omokawa Takamasa Shimizu Kenji Kawate Tadanobu Onishi Yasuhito Tanaka | 2017 | World Journal of Orthopedics2017，8，10： | 2 |
