| 1 | Prognostic significance of the lymphocyte-to-monocyte ratio in patients with metastatic colorectal cancer显示文摘AIM:To evaluate the prognostic significance of the lymphocyte to monocyte ratio(LMR) in patients with unresectable metastatic colorectal cancer who received palliative chemotherapy.METHODS:A total of 104 patients with unresectable metastatic colorectal cancer who underwent palliative chemotherapy were enrolled. The LMR was calculated from blood samples by dividing the absolute lymphocyte count by the absolute monocyte count. Pretreatment LMR values were measured within one week before the initiation of chemotherapy,while posttreatment LMR values were measured eight weeks after the initiation of chemotherapy.RESULTS:The median pre-treatment LMR was 4.16(range:0.58-14.06). We set 3.38 as the cut-off level based on the receiver operating characteristic curve. Based on the cut-off level of 3.38,66 patients were classified into the high pre-treatment LMR group and 38 patients were classified into the low pretreatment LMR group. The low pre-treatment LMR group had a significantly worse overall survival rate(P = 0.0011). Moreover,patients who demonstrated low pre-treatment LMR and normalization after treatmentexhibited a better overall survival rate than the patients with low pre-treatment and post-treatment LMR values.CONCLUSION:The lymphocyte to monocyte ratio is a useful prognostic marker in patients with unresectable metastatic colorectal cancer who receive palliative chemotherapy. | Masatsune Shibutani Kiyoshi Maeda Hisashi Nagahara Hiroshi Ohtani Katsunobu Sakurai Sadaaki Yamazoe Kenjiro Kimura Takahiro Toyokawa Ryosuke Amano Hiroaki Tanaka Kazuya Muguruma Kosei Hirakawa | 2015 | World Journal of Gastroenterology2015，21，34： | 19 |
| 2 | A combination treatment of entecavir and early-phase corticosteroid in severe exacerbation of chronic hepatitis B显示文摘Of patients with severe exacerbation of chronic hepatitis B accompanied by jaundice and coagulopathy,20%-30%have a fatal outcome.In this report,we describe 2 cases of severe exacerbation of chronic hepatitis B with jaundice and coagulopathy who were successfully treated with a combination of entecavir and corticosteroid.In both cases,rapid reductions in serum hepatitis B virus(HBV)-DNA levels were observed,and corticosteroid was stopped after serum HBV-DNA levels became undetectable.Entecavir treatment was continued.Generally,entecavir treatment reduced serum HBV-DNA levels rapidly,although the improvement in liver function was delayed by a few weeks.During this time lag,liver cell injury continued and the disease progressed.Corticosteroid suppressed the excessive host immune response and was useful for stopping progressive deterioration.A combination of entecavir and early-phase corticosteroid may be a useful treatment in severe exacerbation of chronic hepatitis B. | Kazuyuki Matsumoto Yasuhiro Miyake Hirokazu Miyatake Masahiro Takahara Takayuki Imada Satoru Yagi Tatsuya Toyokawa Morihito Nakatsu Masaharu Ando Mamoru Hirohata | 2009 | World Journal of Gastroenterology2009，15，13： | 16 |
| 3 | Current status in remnant gastric cancer after distal gastrectomy显示文摘Remnant gastric cancer(RGC) and gastric stump cancer after distal gastrectomy(DG) are recognized as the same clinical entity. In this review, the current knowledges as well as the non-settled issues of RGC are presented. Duodenogastric reflux and denervation of the gastric mucosa are considered as the two main factors responsible for the development of RGC after benign disease. On the other hand, some precancerous circumstances which already have existed at the time of initial surgery, such as atrophic gastritis and intestinal metaplasia, are the main factors associated with RGC after gastric cancer. Although eradication of Helicobacter pylori(H. pylori) in remnant stomach is promising, it is still uncertain whether it can reduce the risk of carcinogenesis. Periodic endoscopic surveillance after DG was reported useful in detecting RGC at an early stage, which offers a chance to undergo minimally invasive endoscopic treatment or laparoscopic surgery and leads to an improved prognosis in RGC patients. Future challenges may be expected to elucidate the benefit of eradication of H. pylori in the remnant stomach if it could reduce the risk for RGC, to build an optimal endoscopic surveillance strategy after DG by stratifying the risk for development of RGC, and to develop a specific staging system for RGC for the standardization of the treatment by prospecting the prognosis. | Masaichi Ohira Takahiro Toyokawa Katsunobu Sakurai Naoshi Kubo Hiroaki Tanaka Kazuya Muguruma Masakazu Yashiro Naoyoshi Onoda Kosei Hirakawa | 2016 | World Journal of Gastroenterology2016，22，8： | 15 |
| 4 | A case of hepatic angiomyolipoma difficult to distinguish from hepatocellular carcinoma显示文摘We report a case of hepatic angiomyolipoma with uncommon clinical features. A 56-year-old man presented with a hepatic tumor in the caudate lobe. The tumor was hypoechoic on ultrasonography, showed early-phase hyperattenuation on enhanced computed tomography and did not absorb iron on superparamagnetic iron oxide-enhanced magnetic resonance imaging. Hepatocellular carcinoma was highly suspected, and the patient underwent hepatic resection. Histologically, the tumor was mainly composed of smooth muscle cells and contained small amounts of adipose cells and blood vessels. On immunohistochemical staining, the smooth muscle cells were positive for a melanocytic cell-specific monoclonal antibody. In cases with uncommon features of angiomyolipoma, it is quite difficult to distinguish angiomyolipoma from hepatocellular carcinoma. | Masahiro Takahara Yasuhiro Miyake Kazuyuki Matsumoto Daisuke Kawai Eisuke Kaji Tatsuya Toyokawa Morihito Nakatsu Masaharu Ando Mamoru Hirohata | 2009 | World Journal of Gastroenterology2009，15，23： | 8 |
| 5 | Dual therapy for third-line Helicobacter pylori eradication and urea breath test prediction显示文摘We evaluated the efficacy and tolerability of a dual therapy with rabeprazole and amoxicillin (AMX) as an empiric third-line rescue therapy. In patients with failure of first-line treatment with a proton pump inhibitor (PPI)- AMX-clarithromycin regimen and second-line treatment with the PPI-AMX-metronidazole regimen, a third-line eradication regimen with rabeprazole (10 mg q.i.d.) and AMX (500 mg q.i.d.) was prescribed for 2 wk. Eradication was confirmed by the results of the 13C-urea breath test (UBT) at 12 wk after the therapy. A total of 46 patients were included; however, two were lost to followup. The eradication rates as determined by per-protocol and intention-to-treat analyses were 65.9% and 63.0%,respectively. The pretreatment UBT results in the subjects showing eradication failure; those patients showing successful eradication comprised 32.9 ± 28.8 permil and 14.8 ± 12.8 permil, respectively. The pretreatment UBT results in the subjects with eradication failure were significantly higher than those in the patients with successful eradication (P = 0.019). A low pretreatment UBT result (≤ 28.5 permil) predicted the success of the eradication therapy with a positive predictive value of 81.3% and a sensitivity of 89.7%. Adverse effects were reported in 18.2% of the patients, mainly diarrhea and stomatitis. Dual therapy with rabeprazole and AMX appears to serve as a potential empirical third-line strategy for patients with low values on pretreatment UBT. | Toshihiro Nishizawa Hidekazu Suzuki Takama Maekawa Naohiko Harada Tatsuya Toyokawa Toshio Kuwai Masanori Ohara Takahiro Suzuki Masahiro Kawanishi Kenji Noguchi Toshiyuki Yoshio Shinji Katsushima Hideo Tsuruta Eiji Masuda Munehiro Tanaka Shunsuke Katayama Norio Kawamura Yuko Nishizawa Toshifumi Hibi Masahiko Takahashi | 2012 | World Journal of Gastroenterology2012，18，21： | 4 |
| 6 | Management of gastric mucosa-associated lymphoid tissue lymphoma in patients with extra copies of the MALT1 gene显示文摘AIM To identify the clinical features of gastric mucosaassociated lymphoid tissue(MALT) lymphoma with extra copies of MALT1.METHODS This is a multi-centered,retrospective study. We reviewed 146 patients with MALT lymphoma in the stomach who underwent fluorescence in situ hybridization analysis for t(11;18) translocation. Patients were subdivided into patients without t(11;18) translocation or extra copies of MALT1(Group A,n = 88),patients with t(11;18) translocation(Group B,n = 27),and patients with extra copies of MALT1(Group C,n = 31). The clinical background,treatment,and outcomes of each group were investigated.RESULTS Groups A and C showed slight female predominance,whereas Group B showed slight male predominance. Mean ages and clinical stages at lymphoma diagnosis were not different between groups. Complete response was obtained in 61 patients in Group A(69.3%),22 in Group B(81.5%),and 21 in Group C(67.7%). Helicobacter pylori(H. pylori) eradication alone resulted in complete remission in 44 patients in Group A and 13 in Group C. In Group B,14 patients underwent radiotherapy alone,which resulted in lymphoma disappearance. Although the difference was not statistically significant,event-free survival in Group C tended to be inferior to that in Group A(P = 0.10).CONCLUSION Patients with t(11;18) translocation should be treated differently from others. Patients with extra copies of MALT1 could be initially treated with H. pylori eradication,similar to patients without t(11;18) translocation or extra copies of MALT1. | Masaya Iwamuro Ryuta Takenaka Masahiro Nakagawa Yuki Moritou Shunsuke Saito Shinichiro Hori Tomoki Inaba Yoshinari Kawai Tatsuya Toyokawa Takehiro Tanaka Tadashi Yoshino Hiroyuki Okada | 2017 | World Journal of Gastroenterology2017，23，33： | 3 |
| 7 | Two-stage treatment with hepatectomy and carbon-ion radiotherapy for multiple hepatic epithelioid hemangioendotheliomas显示文摘Hepatic epithelioid hemangioendothelioma(HEH)is a rare neoplasm of vascular origin with variable malignant potential.Because most patients with this condition have multiple bilobar lesions,liver transplantation is the standard treatment,and hepatectomy is much less frequently indicated.We describe a case of a 35-yearold woman with unresectable multiple bilobar HEH successfully treated by combination treatment with hepatectomy and carbon-ion radiotherapy.This case is very meaningful since it demonstrated the effectiveness of carbon-ion radiotherapy for HEH and the possibility of expanding the curative treatment options for multiple bilobar hepatic tumors. | Shohei Komatsu Takeshi Iwasaki Yusuke Demizu Kazuki Terashima Osamu Fujii Atsushi Takebe Akihiro Toyokawa Kazuhiro Teramura Takumi Fukumoto Yonson Ku Nobukazu Fuwa | 2014 | World Journal of Gastroenterology2014，20，26： | 2 |
| 8 | Laparoscopic splenectomy for histiocytic sarcoma of the spleen显示文摘Primary histiocytic sarcoma of the spleen is a rare but potentially lethal condition. It can remain asymptomatic or only mildly symptomatic for a long time. An 81-year-old woman presented with an extremely enlarged spleen. She suffered from progressive anemia and required a red blood cell transfusion once a month. Although computed tomography, ultrasonography, and magnetic resonance imaging were performed for diagnosis, a confirmed diagnosis was not obtained. Her enlarged spleen compressed her stomach, and she suffered from gastritis and a sense of gastric fullness just after meals. She underwent laparoscopic splenectomy for therapeutic and diagnostic purposes. Her postoperative course was uneventful. After surgery, her red blood cell and platelet counts increased markedly. The tumor was diagnosed as splenic histiocytic sarcoma. Post-surgical chemotherapy was not performed, and the patient died of liver failure due to liver metastasis 5 mo after surgery. Laparoscopic splenectomy is minimally invasive and useful for the relief of symptoms related to hematological disorders. However, in cases of an enlarged spleen, optimal views and working space are limited. In such cases, splenic artery ligation can markedly reduce the size of the spleen, thus facilitating the procedure. The case reported herein suggests that laparoscopic splenectomy may be useful for the treatment of splenic malignancy. | Satoshi Yamamoto Tadashi Tsukamoto Akishige Kanazawa Sadatoshi Shimizu Keiichiro Morimura Takahiro Toyokawa Zhang Xiang Katsunobu Sakurai Tatsunari Fukuoka Kayo Yoshida Mamiko Takii Ken Inoue | 2013 | World Journal of Gastrointestinal Surgery2013，5，4： | 2 |
