| 1 | Histopathological validation of magnifying endoscopy for diagnosis of mixed-histological-type early gastric cancer显示文摘BACKGROUND The undifferentiated-type(UDT)component profoundly affects the clinical course of early gastric cancers(EGCs).However,an accurate preoperative diagnosis of the histological types is unsatisfactory.To date,few studies have investigated whether the UDT component within mixed-histological-type(MT)EGCs can be recognized preoperatively.AIM To clarify the histopathological characteristics of the endoscopically-resected MT EGCs for investigating whether the UDT component could be recognized preoperatively.METHODS This was a single-center retrospective study.First,we attempted to clarify the histopathological characteristics of the endoscopically-resected MT EGCs with emphasis on the UDT component.Histopathological examination investigated each lesion’s UDT component:(1)Whole mucosal layer occupation of the UDT component;(2)UDT component exposure to the surface of the mucosa;and(3)existence of a clear border between the differentiated-type and UDT components.Then,preoperative endoscopic images with magnifying endoscopy with narrowband imaging(ME-NBI)were examined to identify whether the endoscopic UDT component finding was recognizable within the area where it was present in the histopathological examination.The preoperative biopsy results and comparative relationships between endoscopic and histopathological findings were also examined.RESULTS In the histopathological examination,the whole mucosal layer occupation of the UDT component and exposure of the UDT component to the mucosal surface were observed in 67.3%(33/49)and 79.6%(39/49)of samples,respectively.A clear distinction of the border between the differentiated-type and UDT components could not be drawn in 65.3%(32/49)of MT lesions.In the endoscopic examination,the preoperative endoscopic images showed that only 24.5%(12/49)of MT EGCs revealed the UDT component within the area where it was present histopathologically.Histopathological UDT predominance was the single significant factor associated with the presence of the endoscopic UDT component finding(61.5%vs 11.1%,P=0.0009).Only 26.5%(13/49)of the lesions were diagnosed from the pretreatment biopsy as having a UDT component.Combined results of the pretreatment biopsy and ME-NBI showed the preoperative presence of the UDT component in 40.8%(20/49)of MT EGCs.CONCLUSION Recognition of a UDT component within MT EGCs is difficult even when pretreatment biopsy and ME-NBI are combined.Endoscopic resection plays a significant role in both treatment and diagnosis. | Yuichiro Ozeki Kingo Hirasawa Ryosuke Kobayashi Chiko Sato Yoko Tateishi Atsushi Sawada Ryosuke Ikeda Masafumi Nishio Takehide Fukuchi Makomo Makazu Masataka Taguri Shin Maeda | 2020 | World Journal of Gastroenterology2020，26，36： | 5 |
| 2 | Comparison of unenhanced magnetic resonance imaging and ultrasound in detecting very small hepatocellular carcinoma显示文摘BACKGROUND In hepatocellular carcinoma(HCC),detection and treatment prior to growth beyond 2 cm are important as a larger tumor size is more frequently associated with microvascular invasion and/or satellites.In the surveillance of very small HCC nodules(≤2 cm in maximum diameter,Barcelona clinical stage 0),we demonstrated that the tumor markers alpha-fetoprotein and PIVKA-Ⅱare not so useful.Therefore,we must survey with imaging modalities.The superiority of magnetic resonance imaging(MRI)over ultrasound(US)to detect HCC was confirmed in many studies.Although enhanced MRI is now performed to accurately diagnose HCC,in conventional clinical practice for HCC surveillance in liver diseases,unenhanced MRI is widely performed throughout the world.While,MRI has made marked improvements in recent years.AIM To make a comparison of unenhanced MRI and US in detecting very small HCC that was examined in the last ten years in patients in whom MRI and US examinations were performed nearly simultaneously.METHODS In 394 patients with very small HCC nodules,those who underwent MRI and US at nearly the same time(on the same day whenever possible or at least within 14 days of one another)at the first diagnosis of HCC were selected.The detection rate of HCC with unenhanced MRI was investigated and compared with that of unenhanced US.RESULTS The sensitivity of unenhanced MRI for detecting very small HCC was 95.1%(97/102,95%confidence interval:90.9-99.3)and that of unenhanced US was 69.6%(71/102,95%confidence interval:60.7-78.5).The sensitivity of unenhanced MRI for detecting very small HCC was significantly higher than that of unenhanced US(P<0.001).Regarding the location of HCC in the liver in patients in whom detection by US was unsuccessful,S7-8 was identified in 51.7%.CONCLUSION Currently,unenhanced MRI is a very useful tool for the surveillance of very small HCC in conventional clinical follow-up practice. | Kazuo Tarao Akito Nozaki Hirokazu Komatsu Tatsuji Komatsu Masataka Taguri Katsuaki Tanaka Testuo Yoshida Hideki Koyasu Makoto Chuma Kazushi Numata Shin Maeda | 2021 | World Journal of Hepatology2021，13，6： | 3 |
| 3 | Real impact of tumor marker AFP and PIVKA-II in detecting very small hepatocellular carcinoma(≤2 cm,Barcelona stage 0)-assessment with large number of cases显示文摘BACKGROUND In hepatocellular carcinoma(HCC),detection and treatment prior to growth beyond 2 cm are relevant as a larger tumor size is more frequently associated with microvascular invasion and/or satellites.AIM To examine the impact of the tumor marker alpha-fetoprotein(AFP)or PIVKA-II in detecting very small HCC nodules(≤2 cm in maximum diameter,Barcelona stage 0)in the large number of very small HCC.The difference in the behavior of these tumor markers in HCC development was also examined.METHODS A total of 933 patients with single-nodule HCC were examined.They were subdivided into 394 patients with HCC nodules≤2 cm in maximum diameter and 539 patients whose nodules were>2 cm.The rates of patients whose AFP and PIVKA-II showed normal values were examined.RESULTS The positive ratio of the marker PIVKA-II was significantly different(P<0.0001)between patients with nodules≤2 cm in diameter and those with nodules>2 cm,but there was no significant difference in AFP(P=0.4254).In the patients whose tumor was≤2 cm,50.5%showed normal levels in AFP and 68.8%showed normal levels in PIVKA-II.In 36.4%of those patients,both AFP and PIVKA-II showed normal levels.The PIVKA-II-positive ratio was markedly increased with an increase in the tumor size.In contrast,the positivity in AFP was increased gradually and slowly.CONCLUSION In the surveillance of very small HCC nodules(≤2 cm in diameter,Barcelona clinical stage 0)the tumor markers AFP and PIVKA-II are not so useful. | Kazuo Tarao Akito Nozaki Hirokazu Komatsu Tatsuji Komatsu Masataka Taguri Katsuaki Tanaka Makoto Chuma Kazushi Numata Shin Maeda | 2020 | World Journal of Hepatology2020，12，11： | 2 |

| 7 | Third-look endoscopy prevents delayed bleeding after endoscopic submucosal dissection under antithrombotic therapy显示文摘BACKGROUND Postoperative delayed bleeding(PDB) after gastric endoscopic submucosal dissection(ESD) is the most common adverse event in patients receiving antithrombotics even with second-look endoscopy. Moreover, with the increasing prevalence of cardiovascular and cerebrovascular diseases in an aging population with associated lifestyle-related diseases, an increasing number of patients receive antithrombotics. Several attempts have been made to prevent PDB in aging population;however, a consensus has yet to be reached.AIM To examine the efficacy of third-look endoscopy(TLE) for PDB prevention.METHODS One hundred patients with early gastric neoplasms receiving antithrombotics were prospectively enrolled and subjected to ESD with TLE between February 2017 and July 2019. The primary endpoint was PDB rate, which was compared with our preset threshold. Furthermore, we divided the bleeding period into early-and late-onset PDB(E-PDB and L-PDB, respectively) and analyzed its rate. As a secondary analysis, we compared PDB rates with those of a historical control group, using propensity score matching, and calculated the PDB rates per antithrombotic agent use in each group.RESULTS In total, 96 patients and 114 specimens were finally evaluated. The overall PDB rate was 7.9%(9/114) [90%CI: 4.7-13.1, P = 0.005], while the late-and early-onset PDB rates(L-PDB and E-PDB) were 5.3% [90%CI: 2.7-9.9, P < 0.0001] and 2.6% [90%CI: 1.1-6.4, P = 0.51], respectively. Propensity score matching generated 58 matched pairs for TLE and control groups. No differences were found in overall PDB incidence(10.3% vs 20.7%, P = 0.12), whereas L-PDB occurrence significantly differed(5.2% vs 17.2%, P = 0.04) between groups. Considering antithrombotics' use, the overall PDB rate was higher for direct oral anticoagulants and multiple antithrombotics in the control group, while L-PDB incidence was lower in the TLE group for these agents(8.7% vs 23.1% and 5.0% vs 29.4%, respectively).CONCLUSION TLE for gastric ESD reduces overall PDB, and especially L-PDB incidence, among patients receiving antithrombotics. | Ryosuke Ikeda Kingo Hirasawa Chiko Sato Yuichiro Ozeki Atsushi Sawada Masafumi Nishio Takehide Fukuchi Ryosuke Kobayashi Makomo Makazu Masataka Taguri Shin Maeda | 2020 | World Journal of Gastroenterology2020，26，41： | 2 |

| 14 | Difference in incidence of developing hepatocellular carcinoma between hepatitis B virus-and hepatitis C virus-infected patients显示文摘BACKGROUND It is generally accepted that the incidence of hepatocellular carcinoma(HCC)in hepatitis C virus(HCV)-associated patients is higher than that in hepatitis B virus(HBV)-associated patients.The reason why this difference in the incidence of HCC occurs in patients with HBV and HCV infections remains unclear.We report the possibility that the contributing power of inflammation,which is the main risk factor for developing HCC,may be different with HBV and HCV infections.AIM To investigate this,we surveyed the hazard ratio of inflammation for HCC development which was identified by serum alanine aminotransferase(ALT)levels between patients with HBV and HCV infections.METHODS The PubMed database was searched(2001-2021)for studies published in English regarding the incidence of HCC identifying 8924 HBV-and 7376 HCV-infected patients.From these studies,interferon-treated patients with both HBV and HCV infections were excluded.Furthermore,in HBV patients,those administered nucleos(t)ide analogues were excluded,and in HCV patients,those administered direct acting antivirals were also excluded.Studies citing hazard ratios of HCC regarding inflammation(serum elevated alanine aminotransferase levels)were selected.Finally,there were 14 studies of HBV-infected patients and 8 studies of HCV-infected patients.We calculated the hazard ratio in patients in an inflammatory state(serum ALT levels were above the normal range).RESULTS In the 14 studies of HBV patients,the average hazard ratio(HR)of elevated ALT for developing HCC was 2.74[1.98-3.77]and that in the 8 studies of HCV-infected patients was 5.51[3.08-9.83].The HR of inflammation for HCC development in HCV-associated liver diseases is about twice that in HBV-associated liver diseases.HR in HCV-infected patients was significantly(P=0.0391)higher than that in HBV-infected patients.In hepatitis B patients,the abnormal range adopted was 28-45 IU/L,and in hepatitis C patients,it was 20-50 IU/L.It was demonstrated that the abnormal ALT levels adopted in hepatitis B and C patients were very similar in this series.CONCLUSION The difference in the incidence of HCC development between HBV and HCV patients may depend on the difference in the hazard risk of ALT between HBV and HCV infections. | Kazuo Tarao Akito Nozaki Hirokazu Komatsu Naomi Ideno Tatsuji Komatsu Takaaki Ikeda Masataka Taguri Shin Maeda | 2022 | World Journal of Meta-Analysis2022，10，3： | 1 |
