| 1 | Progression of remnant gastric cancer is associated with duration of follow-up following distal gastrectomy显示文摘AIM: To re-evaluate the recent clinicopathological features of remnant gastric cancer (RGC) and to develop desirable surveillance programs. METHODS: Between 1997 and 2008, 1149 patients underwent gastrectomy for gastric cancer at the Department of Digestive Surgery, Kyoto Prefectural University of Medicine, Japan. Of these, 33 patients underwent gastrectomy with lymphadenectomy for RGC. Regarding the initial gastric disease, there were 19 patients with benign disease and 14 patients with gastric cancer. The hospital records of these patients were reviewed retrospectively. RESULTS: Concerning the initial gastric disease, the RGC group following gastric cancer had a shorter interval [P < 0.05; gastric cancer vs benign disease: 12 (2-22) vs 30 (4-51) years] and were more frequently reconstructed by Billroth-Ⅰ procedure than those following benign lesions (P < 0.001). Regarding reconstruction, RGC following Billroth-Ⅱ reconstruction showed a longer interval between surgical procedures [P < 0.001; Billroth-Ⅱ vs Billroth-Ⅰ: 32 (5-51) vs 12 (2-36) years] and tumors were more frequently associated with benign disease (P < 0.001) than those following Billroth-Ⅰ reconstruction. In tumor location of RGC, after Billroth-Ⅰ reconstruction, RGC occurred more frequently near the suture line and remnant gastric wall. After Billroth-Ⅱ reconstruction, RGC occurred more frequently at the anastomotic site. The duration of follow-up was significantly associated with the stage of RGC (P < 0.05). Patients diagnosed with early stage RGC such as stage Ⅰ-Ⅱ tended to have been followed up almost every second year. CONCLUSION: Meticulous follow-up examination and early detection of RGC might lead to a better prognosis. Based on the initial gastric disease and the procedure of reconstruction, an appropriate follow-up interval and programs might enable early detection of RGC. | Shuhei Komatsu Daisuke Ichikawa Kazuma Okamoto Daito Ikoma Masahiro Tsujiura Yukihisa Nishimura Yasutoshi Murayama Atsushi Shiozaki Hisashi Ikoma Yoshiaki Kuriu Masayoshi Nakanishi Hitoshi Fujiwara Toshiya Ochiai Yukihito Kokuba Eigo Otsuji | 2012 | World Journal of Gastroenterology2012，18，22： | 25 |
| 2 | Improving recognition of hepatic perivascular epithelioid cell tumor:Case report and literature review显示文摘A 58-year-old man presented with the chief complaint of abdominal bloating and was incidentally found to have a liver tumor.As diagnostic imaging studies could not rule out malignancy,the patient underwent partial resection of segment 3 of the liver.The lesion pathologically showed eosinophilic proliferation,in addition to immunohistochemical positivity for human melanoma black 45 and Melan-A,thereby leading to the diagnosis of a hepatic perivascular epithelioid cell tumor(PEComa).A PEComa arising from the liver is relatively rare.Moreover,the name ‘PEComa' has not yet been widely recognized,and the same disease entity has been called epithelioid angiomyolipoma(EAML),further diminishing the recognition of PEComa.In addition,PEComa imaging findings mimic those of malignant liver tumors,and clinically,this tumor tends to enlarge.Therefore,a PEComa is difficult to diagnose.We conducted a systematic review of PEComa and EAML cases and discuss the results,including findings useful for differentiating perivascular epithelioid cell tumors from malignant liver tumors. | Toshiya Maebayashi Katsumi Abe Takuya Aizawa Masakuni Sakaguchi Naoya Ishibashi Osamu Abe Tadatoshi Takayama Hisashi Nakayama Shunichi Matsuoka Kazushige Nirei Hitomi Nakamura Masahiro Ogawa Masahiko Sugitani | 2015 | World Journal of Gastroenterology2015，21，17： | 20 |
| 3 | Optimal duration of the early and late recurrence of hepatocellular carcinoma after hepatectomy显示文摘AIM: To determine the best cut-off value between the early and late recurrence periods after the initial recurrence of hepatocellular carcinoma(HCC).METHODS: The clinical records of 404 patients who underwent macroscopic curative hepatectomy for HCC between 1980 and 2010 were retrospectively examined. We divided the 252 patients experienced a recurrence of HCC into two groups, the early and late recurrence groups using the 'minimum P-value' approach. Factors for early recurrence were investigated using all 404 patients, and factors related to late recurrence were investigated in the patients who were confirmed to be recurrence free at the end of the early recurrence period.RESULTS: For the 252 patients who experienced a recurrence, the optimal cut-off value for differentiating early and late recurrence based on the overall survival after initial recurrence was 17 mo(5-year overall survival after initial recurrence: 15.4% vs 36.3%, P = 0.000018). Cox proportional hazard analysis identified early recurrence(P = 0.003) as one of the independent prognostic factors associated with overall survival after initial recurrence. A logistic regression model showed that an alpha-fetoprotein level > 100 ng/m L(P < 0.001), multiple HCC(P < 0.001), serosal invasion(P = 0.031), and microvascular invasion(P = 0.012) were independent factors associated with early recurrence, whereas the only independent factor related to late recurrence was liver cirrhosis(P = 0.002).CONCLUSION: Seventeen months after hepatectomy is a useful cut-off value between early and late recurrence of HCC based on the prognosis and different etiologies. | Yusuke Yamamoto Hisashi Ikoma Ryo Morimura Hirotaka Konishi Yasutoshi Murayama Shuhei Komatsu Atsushi Shiozaki Yoshiaki Kuriu Takeshi Kubota Masayoshi Nakanishi Daisuke Ichikawa Hitoshi Fujiwara Kazuma Okamoto Chouhei Sakakura Toshiya Ochiai Eigo Otsuji | 2015 | World Journal of Gastroenterology2015，21，4： | 14 |
| 4 | Surgical treatment of hepatocellular carcinoma with severe intratumoral arterioportal shunt显示文摘We report a case of hepatocellular carcinoma (HCC) that caused a severe arterioportal shunt (APS). A 49-year-old man was admitted to hospital due to esophagogastric variceal hemorrhage and HCC, and underwent endoscopic variceal ligation (EVL) and endoscopic injection sclerotherapy (EIS). He was then referred to our hospital. Abdominal computed tomography revealed a lowdensity lesion in the posterior segment of the liver and an intratumoral APS, which caused portal hypertension. Although the patient underwent EVL, EIS, Hassab’s operation, and transcatheter arterial embolization for APS, he vomited blood due to rupture of esophagogastric varices. Right hepatectomy was performed for the treatment of HCC and APS, although the indocyanine green retention value at 15 min after intravenous injection was poor (30%). The patient’s postoperative course was uneventful. Eventually, APS disappeared and the esophagogastric varices improved. | Hiromichi Ishii Teruhisa Sonoyama Shingo Nakashima Hiroyuki Nagata Atsushi Shiozaki Yoshiaki Kuriu Hisashi Ikoma Masayoshi Nakanishi Daisuke Ichikawa Hitoshi Fujiwara Kazuma Okamoto Toshiya Ochiai Yukihito Kokuba Chohei Sakakura Eigo Otsuji | 2010 | World Journal of Gastroenterology2010，16，25： | 11 |
| 5 | High concentrations of human β-defensin 2 in gastric juice of patients with Helicobacter pylori infection显示文摘AIM: Human β-defensin (HBD)-1 and HBD-2 are endogenous antimicrobial peptides. Unlike HBD-1, the HBD-2 expression is augmented by Helicobacter pylori (H pylori). We sought to determine HBD-1 and HBD-2 concentrations in gastric juice duringH pylori infection.METHODS: HBD-1 and HBD-2 concentrations were measured by radioimmunoassay in plasma and gastric juice of 49 H pylori-infected and 33 uninfected subjects and before and after anti-H pyloritreatment in 13 patients with H pylori-associated gastritis. Interleukin (IL)-1β and IL-8 concentrations in gastric juice were measured by enzyme-linked immunosorbent assay (ELISA). Histological grades of gastritis were determined using two biopsy specimens taken from the antrum and corpus. Reverse phase high performance liquid chromatography (RP-HPLC)was used to identify HBD-2.RESULTS: HBD-2 concentrations in gastric juice, but not in plasma, were significantly higher in H pylori-positive than -negative subjects, albeit the post-treatment levels were unchanged. Immunoreactivity for HBD-2 was exclusively identified in H pylori-infected mucosa by RPHPLC. HBD-2 concentrations in gastric juice correlated with histological degree of neutrophil and mononuclear cell infiltration in the corpus. IL-1β levels correlated with those of IL-8, but not HBD-2. Plasma and gastric juice HBD-1concentrations were similar in H pylori-infected and uninfected subjects.CONCLUSION: Our results place the β-defensins, especially HBD-2, in the front line of innate immune defence.Moreover, HBD-2 may be involved in the pathogenesis of H pylori-associated gastritis, possibly through its function as immune and inflammatory mediator. | Hajime Isomoto Hiroshi Mukae Hiroshi Ishimoto Yoshito Nishi Chun-Yang Wen Akihiro Wad Ken Ohnita Toshiya Hirayama Masamitsu Nakazato Shigeru Kohno | 2005 | World Journal of Gastroenterology2005，11，31： | 10 |
| 6 | Post-hepatectomy survival in advanced hepatocellular carcinoma with portal vein tumor thrombosis显示文摘AIM: To analyze hepatocellular carcinoma(HCC) patients with portal vein tumor thrombosis(PVTT) using the tumor-node-metastasis(TNM) staging system.METHODS: We retrospectively analyzed 372 patients with HCC who underwent hepatectomy between 1980 and 2009.We studied the outcomes of HCC patients with PVTT to evaluate the American Joint Committee on Cancer TNM staging system(7th edition) for stratifying and predicting the prognosis of a large cohort of HCC patients after hepatectomy in a single-center.Portal vein invasion(vp) 1 was defined as an invasion or tumor thrombus distal to the second branch of the portal vein,vp2 as an invasion or tumor thrombus in the second branch of the portal vein,vp3 as an invasion or tumor thrombus in the first branch of the portal vein,and vp4 as an invasion or tumor thrombus in the portal trunk or extending to a branch on the contralateral side.RESULTS: The cumulative 5-year overall survival(5yr OS) and 5-year disease-free survival(5yr DFS) rates of the 372 patients were 58.3% and 31.3%,respectively.The 5yr DFS and 5yr OS of vp3-4 patients(n = 10) were 20.0%,and 30.0%,respectively,which was comparable with the corresponding survival rates of vp1-2 patients(P = 0.466 and 0.586,respectively).In the subgroup analysis of patients with macroscopic PVTT(vp2-4),the OS of the patients who underwent preoperative transarterial chemoembolization was comparable to that of patients who did not(P = 0.747).There was a significant difference in the DFS between patients with stage Ⅰ HCC and those with stage Ⅱ HCC(5yr DFS 39.2% vs 23.1%,P < 0.001); however,theDFS for stage Ⅱ was similar to that for stage Ⅲ(5yrD FS 23.1% vs 13.8%,P = 0.330).In the subgroup analysis of stage Ⅱ-Ⅲ HCC(n = 148),only alpha-fetoprotein(AFP) > 100 mg/dL was independently associated with DFS.CONCLUSION: Hepatectomy for vp3-4 HCC results in a survival rate similar to hepatectomy for vp1-2.AFP stratified the stage Ⅱ-Ⅲ HCC patients according to prognosis. | Yusuke Yamamoto Hisashi Ikoma Ryo Morimura Katsutoshi Shoda Hirotaka Konishi Yasutoshi Murayama Shuhei Komatsu Atsushi Shiozaki Yoshiaki Kuriu Takeshi Kubota Masayoshi Nakanishi Daisuke Ichikawa Hitoshi Fujiwara Kazuma Okamoto Chouhei Sakakura Toshiya Ochiai Eigo Otsuji | 2015 | World Journal of Gastroenterology2015，21，1： | 9 |
| 7 | Hepatectomy for hepatocellular carcinoma with portal vein tumor thrombus显示文摘Despite surgical removal of tumors with portal vein tumor thrombus(PVTT) in hepatocellular carcinoma(HCC) patients, early recurrence tends to occur, and overall survival(OS) periods remain extremely short. The role that hepatectomy may play in long-term survival for HCC with PVTT has not been established. The operative mortality of hepatectomy for HCC with PVTT has also not been reviewed. Hence, we reviewed recent literature to assess these parameters. The OS of patients who received hepatectomy in conjunction with multidisciplinary treatment tended to be superior to that of patients who did not. Multidisciplinary treatments included the following: preoperative radiotherapy on PVTT; preoperative transarterial chemoembolization(TACE); subcutaneous administration of interferon-alpha(IFN-α) and intra-arterial infusion of 5-fluorouracil(5-FU) with infusion chemotherapy in the affected hepatic artery; cisplatin, doxorubicin and 5-FU locally administered in the portal vein; and subcutaneous injection of IFN-α, adjuvant chemotherapy(5-FU + Adriamycin) administration via the portal vein with postoperative TACE, percutaneous isolated hepatic perfusion and hepatic artery infusion and/or portal vein chemotherapy. The highest reported rate of operative mortality was 9.3%. In conclusion, hepatectomy for patients affected by HCC with PVTT is safe, has low mortality and might prolong survival in conjunction with multidisciplinary treatment. | Toshiya Kamiyama Tatsuhiko Kakisaka Tatsuya Orimo Kenji Wakayama | 2017 | World Journal of Hepatology2017，9，36： | 8 |
| 8 | Significance of functional hepatic resection rate calculated using 3D CT/^(99m)Tc-galactosyl human serum albumin singlephoton emission computed tomography fusion imaging显示文摘AIM: To evaluate the usefulness of the functional hepatic resection rate(FHRR) calculated using 3D computed tomography(CT)/^(99m)Tc-galactosyl-human serum albumin(GSA) single-photon emission computed tomography(SPECT) fusion imaging for surgical decision making. METHODS: We enrolled 57 patients who underwent bi- or trisectionectomy at our institution between October 2013 and March 2015. Of these, 26 patients presented with hepatocellular carcinoma, 12 with hilar cholangiocarcinoma, six with intrahepatic cholangiocarcinoma, four with liver metastasis, and nine with other diseases. All patients preoperatively underwent three-phase dynamic multidetector CT and ^(99m)Tc-GSA scintigraphy. We compared the parenchymal hepatic resection rate(PHRR) with the FHRR, which was defined as the resection volume counts per total liver volume counts on 3D CT/^(99m)Tc-GSA SPECT fusion images.RESULTS: In total, 50 patients underwent bisectionectomy and seven underwent trisectionectomy.Biliary reconstruction was performed in 15 patients, including hepatopancreatoduodenectomy in two. FHRR and PHRR were 38.6 ± 19.9 and 44.5 ± 16.0, respectively; FHRR was strongly correlated with PHRR. The regression coefficient for FHRR on PHRR was 1.16(P < 0.0001). The ratio of FHRR to PHRR for patients with preoperative therapies(transcatheter arterial chemoembolization, radiation, radiofrequency ablation, etc.), large tumors with a volume of > 1000 m L, and/or macroscopic vascular invasion was significantly smaller than that for patients without these factors(0.73 ± 0.19 vs 0.82 ± 0.18, P < 0.05). Postoperative hyperbilirubinemia was observed in six patients. Major morbidities(Clavien-Dindo grade ≥ 3) occurred in 17 patients(29.8%). There was no case of surgeryrelated death.CONCLUSION: Our results suggest that FHRR is an important deciding factor for major hepatectomy, because FHRR and PHRR may be discrepant owing to insufficient hepatic inflow and congestion in patients with preoperative therapies, macroscopic vascular invasion, and/or a tumor volume of > 1000 m L. | Yosuke Tsuruga Toshiya Kamiyama Hirofumi Kamachi Shingo Shimada Kenji Wakayama Tatsuya Orimo Tatsuhiko Kakisaka Hideki Yokoo Akinobu Taketomi | 2016 | World Journal of Gastroenterology2016，22，17： | 6 |
| 9 | MicroRNA-31 expression in colorectal serrated pathway progression显示文摘MicroRNAs have been increasingly recognized as useful biomarkers for colorectal cancers(CRC).We have recently observed that microRNA-31(miR-31)expression is associated with BRAF mutation and prognosis in CRC.Moreover,high miR-31 expression is frequently detected in sessile serrated adenomas compared with hyperplastic polyps(HPs).These results suggest that miR-31 may contribute to the progression of serrated lesions.At a follow-up colonoscopy,we observed the case of a 75-year-old man with a 7-mm flat-elevated lesion in the cecum and diagnosed the lesion as an early invasive carcinoma with serrated features.Tissue specimens were obtained from the representative areas to compare the molecular alterations in the carcinoma component with those in the HP component.Higher miR-31 expression was observed in the carcinoma component(57-fold increase)and the HP component(8-fold increase)compared with the paired normal mucosa,suggesting that miR-31 may be one of the key molecules in serrated pathway progression. | Hironori Aoki Katsuhiko Nosho Hisayoshi Igarashi Miki Ito Kei Mitsuhashi Takafumi Naito Eiichiro Yamamoto Tokuma Tanuma Masafumi Nomura Hiroyuki Maguchi Toshiya Shinohara Hiromu Suzuki Hiroyuki Yamamoto Yasuhisa Shinomura | 2014 | World Journal of Gastroenterology2014，20，34： | 5 |
| 10 | Endoscopic naso-pancreatic drainage for the treatment of pancreatic fistula occurring after LDLT显示文摘Pancreatic fistula is a quite rare complication in patients who undergo living donor liver transplantation(LDLT).However,in the cases that show pancreatic fistula,the limited volume of the graft and the resultant inadequate liver function may complicate the management of the fistula.As a result,the pancreatic fistula may result in the death of the patient.We present 2 cases in whichendoscopic treatment was effective against pancreatic fistulas that developed after LDLT.In case 1,a 61-yearold woman underwent LDLT for primary biliary cirrhosis.Because of a portal venous thrombus caused by a splenorenal shunt,the patient underwent portal vein reconstruction,and a splenorenal shunt was ligated on postoperative day(POD)7.The main pancreatic duct was injured during the manipulation to achieve hemostasis,thereby necessitating open drainage.However,discharge of pancreatic fluid continued even after POD 300.Endoscopic naso-pancreatic drainage(ENPD)was performed,and this procedure resulted in a remarkable decrease in drain output.The refractory pancreatic fistula healed on day 40 after ENPD.In case 2,a 58-year-old man underwent LDLT for cirrhosis caused by the hepatitis C virus.When the portal vein was exposed during thrombectomy,the pancreatic head was injured,which led to the formation of a pancreatic fistula.Conservative therapy was ineffective;therefore,ENPD was performed.The pancreatic fistula healed on day 38 after ENPD.The findings in these 2 cases show that endoscopic drainage of the main pancreatic duct is a less invasive and effective treatment for pancreatic fistulas that develop after LDLT. | Akihisa Nagatsu Toshiya Kamiyama Satoru Todo Masahiko Taniguchi Tomomi Suzuki Hiroyuki Furukawa Tsuyoshi Shimamura Kenichiro Yamashita Hiroshi Kawakami Daisuke Abo | 2011 | World Journal of Gastroenterology2011，17，30： | 5 |
| 11 | Efects of amine, amine salt and amide on the behaviour of carbon dioxide absorption into calcium hydroxide suspension to precipitate calcium carbonate显示文摘The amount of carbon dioxide(CO2) absorption and calcium ion(Ca2+) concentration besides the pH of aqueous solution were observed during the CO2 absorption to precipitate calcium carbonate(CaCO3) from calcium hydroxide(Ca(OH)2). A reaction rate-limiting efect of an amount of CO2 absorption without any organic additives in the early stage of the precipitation was observed, which was attributed to an interruption efect of bicarbonate ion(HCO 3) on the precipitation of CaCO3. The improvement for the reaction rate was achieved not only by amine additives but also by neutral additives such as ε-caprolactam or amine salt. When the hexamethylene diamine was dissolved in the solution, successive change of crystal forms of CaCO3 aragonite to calcite in aqueous suspensions, confirmed by Ca2+ concentration change and X-ray difraction, was concluded that a local environment around the amine group in aqueous solution and an interaction of the diamine with precipitated CaCO3 particles were important factors for these reactions. | Wittaya Chuajiw Mitsuru Nakano Kazumasa Takatori Toshiya Kojima Yoshiki Wakimoto Yoshiaki Fukushima | 2013 | Journal of Environmental Sciences2013，25，12： | 5 |
| 12 | Clinical impacts of mesothelin expression in gastrointestinal carcinomas显示文摘Mesothelin,C-ERC/mesothelin is a 40-kD a cell surface glycoprotein that is normally present on normal mesothelial cells lining the pleura,peritoneum,and pericardium.Moreover,mesothelin has been shown to be overexpressed in several human cancers,including virtually all mesothelioma and pancreatic cancer approximately 70% of ovarian cancer and extra bile duc cancer,and 50% of lung adenocarcinomas and gastric cancer.The full-length human mesothelin gene encodes the primary product,a 71-k Da precursor protein.The71-kD a mesothelin precursor is cleaved into two products40-k Da C-terminal fragment that remains membranebound via glycosylphosphatidylinositol anchor,and a31-kD a N-terminal fragment,megakaryocyte potentiating factor,which is secreted into the blood.The biologica functions of mesothelin remain largely unknown However,results of recent studies have suggested tha the mesothelin may play a role of cell proliferation and migration.In pancreatic cancer,mesothelin expression was immunohistochemically observed in all cases,bu absent in normal pancreas and in chronic pancreatitis Furthermore,the expression of mesothelin was correlated with an poorer patient outcome in severa human cancers.The limited mesothelin expression in normal tissues and high expression in many cancers makes it an attractive candidate for cancer therapy.The present review discusses the expression and function o mesothelin in cancer cells and the utility of mesothelin as a target of cancer therapy. | Takahiro Einama Futoshi Kawamata Hirofumi Kamachi Hiroshi Nishihara Shigenori Homma Fumihiko Matsuzawa Tatsuzo Mizukami Yuji Konishi Munenori Tahara Toshiya Kamiyama Okio Hino Akinobu Taketomi Satoru Todo | 2016 | World Journal of Gastrointestinal Pathophysiology2016，7，2： | 4 |
| 13 | Silvicultural alternatives to conventional even-aged forest man-agement-what limits global adoption?显示文摘Background: The development of forestry as a scientific and management discipline over the last two centuries has mainly emphasized intensive management operations focused on increased commodity production, mostly wood. This 'conventional' forest management approach has typically favored production of even-aged, single-species stands. While alternative management regimes have generally received less attention, this has been changing over the last three decades, especially in countries with developed economies. Reasons for this change include a combination of new information and concerns about the ecological consequences of intensive forestry practices and a willingness on the part of many forest owners and society to embrace a wider set of management objectives. Alternative silvicultural approaches are characterized by a set of fundamental principles, including avoidance of clearcutting, an emphasis on structural diversity and small-scale variability, deployment of mixed species with natural regeneration,and avoidance of intensive site-preparation methods.Methods: Our compilation of the authors' experiences and perspectives from various parts of the world aims to initiate a larger discussion concerning the constraints to and the potential of adopting alternative silvicultural practices.Results: The results suggest that a wider adoption of alternative silvicultural practices is currently hindered by a suite of ecological, economic, logistical, informational, cultural, and historical constraints. Individual contexts display their own unique combinations and relative significance of these constraints, and accordingly, targeted efforts, such as regulations and incentives, may help to overcome specific challenges.Conclusions: In a broader context, we propose that less emphases on strict applications of principles and on stand structures might provide additional flexibility and facilitate the adoption of alternative silvicultural regimes in a broader set of circumstances. At the same time, the acceptance of alternative silvicultural systems as the 'preferred or default mode of management' wil necessitate and benefit from the continued development of the scientific basis and valuation of a variety of ecosystem goods and services. This publication is aimed to further the discussion in this context. | Klaus J Puettmann Scott McG Wilson Susan C Baker Pablo J Donoso Lars Dr?ssler Girma Amente Brian D Harvey Thomas Knoke Yuanchang Lu Susanna Nocentini Francis E Putz Toshiya Yoshida Jürgen Bauhus | 2015 | Forest Ecosystems2015，2，2： | 4 |

| 15 | Alpha-fetoprotein before and after pegylated interferon therapy for predicting hepatocellular carcinoma development显示文摘AIM: To investigate factors that accurately predict hepatocellular carcinoma(HCC) development after antiviral therapy in chronic hepatitis C(CHC) patients. METHODS: CHC patients who received pegylated interferon and ribavirin were enrolled in this cohort study that investigated the ability of alpha-fetoprotein(AFP) to predict HCC development after interferon(IFN) therapy. RESULTS: Of 1255 patients enrolled, 665 developed sustained virological response(SVR) during mean follow-up period of 5.4 years. HCC was occurred in 89 patients, and 20 SVR patients were included. Proportional hazard models showed that HCC occurred in SVR patients showing AFP ≥ 5 ng/m L before therapy and in non-SVR patients showing AFP ≥ 5 ng/m L before and 1 year after therapy besides older age, and low platelet counts. SVR patients showing AFP ≥ 5 ng/m L before therapy and no decrease in AFP to < 5 ng/m L 1 year after therapy had significantly higher HCC incidence than non-SVR patients showing AFP ≥ 5 ng/m L before therapy and decreased AFP(P = 0.043). AFP ≥ 5 ng/m L before therapy was significantly associated with low platelet counts and high values of alanine aminotransferase(ALT) in stepwise logistic regression analysis. After age, gender, platelet count, and ALT was matched by propensity score, significantly lower HCC incidence was shown in SVR patients showing AFP < 5 ng/m L before therapy than in those showing AFP ≥ 5 ng/m L.CONCLUSION: The criteria of AFP < 5 ng/m L before and 1 year after IFN therapy is a benefical predictor for HCC development in CHC patients. | Yasuto Takeuchi Fusao Ikeda Toshiya Osawa Yasuyuki Araki Kouichi Takaguchi Youichi Morimoto Noriaki Hashimoto Kousaku Sakaguchi Tatsuro Sakata Masaharu Ando Yasuhiro Makino Shuji Matsumura Hiroki Takayama Hiroyuki Seki Shintarou Nanba Yuki Moritou Tetsuya Yasunaka Hideki Ohnishi Akinobu Takaki Kazuhiro Nouso Yoshiaki Iwasaki Kazuhide Yamamoto | 2015 | World Journal of Hepatology2015，7，19： | 3 |
| 16 | Resected tumor seeding in stomach wall due to endoscopic ultrasonography-guided fine needle aspiration of pancreatic adenocarcinoma显示文摘Endoscopic ultrasonography-guided fine needle aspiration(EUS-FNA) is a useful and relatively safe tool for the diagnosis and staging of pancreatic cancer. However, there have recently been several reports of tumor seeding after EUS-FNA of adenocarcinomas. A 78-year-old man was admitted to our hospital due to upper gastric pain. Examinations revealed a 20 mm mass in the pancreatic body, for which EUS-FNA was performed. The cytology of the lesion was adenocarcinoma, and the stage of the cancer was T3N0M0. The patient underwent surgery with curative intent, followed by adjuvant chemotherapy with S-1. An enlarging gastric submucosal tumor was found on gastroscopy at 28 mo after surgery accompanied by a rising level of CA19-9. Biopsy result was adenocarcinoma, consistent with a pancreatic primary tumor. Tumor seeding after EUS-FNA was strongly suspected. The patient underwent surgical resection of the gastric tumor with curative intent. The pathological result of the resected gastric specimen was adenocarcinoma with a perfectly matched mucin special stain result with the previously resected pancreatic cancer. This is the first case report of tumor seeding after EUS-FNA which was surgically resected and inspected pathologically. | Akiko Tomonari Akio Katanuma Tomoaki Matsumori Hajime Yamazaki Itsuki Sano Ryuki Minami Manabu Sen-yo Satoshi Ikarashi Toshifumi Kin Kei Yane Kuniyuki Takahashi Toshiya Shinohara Hiroyuki Maguchi | 2015 | World Journal of Gastroenterology2015，21，27： | 3 |
| 17 | Effect of branched-chain amino acids in patients receiving intervention for hepatocellular carcinoma显示文摘AIM:To investigate the usefulness of branched-chain amino acids(BCAA)before transarterial chemoembolization(TACE)or radiofrequency ablation(RFA).METHODS:We investigated the usefulness of preintervention with BCAAs by comparing patients treated with BCAAs at 12.45 g/d orally for at least 2 wk before TACE or RFA and those not receiving such pretreatment.A total of 270 patients with hepatocellular carcinoma complicated by cirrhosis were included in the study.Mean changes from baseline(Δ)in serum albumin(Alb),C-reactive protein(CRP),and transaminase levels,as well as peak body temperature were also determined and compared at days 2,5,and 10 after the start of TACE or RFA.RESULTS:In patients who underwent TACE or RFA,BCAA pre-intervention significantly suppressed the development of post-intervention hypoalbuminemia and reduced inflammatory reactions during the subsequent clinical course.After TACE,theΔAlb peaked on day 2,remained constantly lower in BCAA-treated patients,compared to the control group,and was-0.13±0.42g/dL in BCAA-treated patients and-0.33±0.51 g/dL in untreated patients on day 10.TheΔCRP was also significantly lower in BCAA-treated patients on days2,5 and 10 after TACE.Like the trends noted after TACE,a similar tendency was noted as to theΔAlb andΔCRP after RFA.The changes in serum Alb level were inversely correlated with CRP changes;therefore,a possible involvement of the anti-inflammatory effect of BCAAs was inferred as a factor contributory to the suppression of decrease in serum Alb level.CONCLUSION:Pre-intervention with BCAAs may hasten the recovery of serum Alb level and mitigate postoperative complications in patients undergoing TACE or RFA. | Tomoaki Ishihara Motoh Iwasa Hideaki Tanaka Masahiko Kaito Jiro Ikoma Toshiya Shibata Yoshiyuki Takei | 2014 | World Journal of Gastroenterology2014，20，10： | 2 |
