| 1 | Successful treatment of conversion chemotherapy for initially unresectable synchronous colorectal liver metastasis显示文摘A 72-year-old woman with a sigmoid colon cancer and a synchronous colorectal liver metastasis(CRLM),which involved the right hepatic vein(RHV)and the inferior vena cava(IVC),was referred to our hospital.The metastatic lesion was diagnosed as initially unresectable because of its invasion into the confluence of the RHV and IVC.After she had undergone laparoscopic sigmoidectomy for the original tumor,she consequently had 3 courses of modified 5-fluorouracil,leucovorin,and oxaliplatin(m FOLFOX6)plus cetuximab.Computed tomography revealed a partial response,and the confluence of the RHV and IVC got free from cancer invasion.After 3 additional courses of m FOLFOX6 plus cetuximab,preoperative percutaneous transhepatic portal vein embolization(PTPE)was performed to secure the future remnant liver volume.Finally,a right hemihepatectomy was performed.The postoperative course was uneventful.The patient was discharged from the hospital on postoperative day 13.She had neither local recurrence nor distant metastasis 18 mo after the last surgical intervention.This multidisciplinary strategy,consisting of conversion chemotherapy using FOLFOX plus cetuximab and PTPE,could contribute in facilitating curative hepatic resection for initially unresectable CRLM. | Kenta Baba Akihiko Oshita Mohei Kohyama Satoshi Inoue Yuta Kuroo Takuro Yamaguchi Hiroyuki Nakamura Yoichi Sugiyama Tatsuya Tazaki Masaru Sasaki Yuji Imamura Yutaka Daimaru Hideki Ohdan Atsushi Nakamitsu | 2015 | World Journal of Gastroenterology2015，21，6： | 10 |
| 2 | Stratifying the risk of lymph node metastasis in undifferentiated-type early gastric cancer显示文摘AIM:To study how lymph node metastasis(LNM) risk is stratified in undifferentiated-type early gastric cancer(undiff-EGC) dependent on combinations of risk factors.METHODS:Five hundred and sixty-seven cases with undiff-EGC undergoing gastrectomy with lymphadenectomy were examined retrospectively.Using clinicopathological factors of patient age,location,size,an endoscopic macroscopic tumor form,ulceration,depth,histology,lymphatic involvement(LI) and venous involvement(VI),LNM risk was examined and stratified by conventional statistical analysis and datamining analysis.RESULTS:LNM was positive in 44 of 567 cases(7.8%).Univariate analysis revealed > 2 cm,protrusion,submucosal(sm),mixed type,LI and VI as significant prognostic factors and > 2 cm and LI-positive were independent factors by multivariate analysis.In preoperatively evaluable factors excluding LVI,sm and > 2 cm were independent factors.According to the depth and size,cases were categorized into the low-risk group [m and ≤ 2 cm,0%(LNM incidence)],the moderaterisk group(m and > 2 cm,5.6%; and sm and ≤ 2 cm,6.0%),and the high-risk group(sm and > 2 cm,19.3%).On the other hand,LNM occurred in 1.4% in all LI-negative cases,greatly lower than 28.2% in all LI-positive cases,and LNM incidence was low in LInegative cases even in the moderate- and high-risk groups.CONCLUSION:LNM-related factors in undiff-EGC were depth and size preoperatively while those were LI and size postoperatively.Among these factors,LI was the most significantly correlated factor. | Yukiko Asakawa Masahiko Ohtaka Shinya Maekawa Mitsuharu Fukasawa Yasuhiro Nakayama Tatsuya Yamaguchi Taisuke Inoue Tomoyoshi Uetake Minoru Sakamoto Tadashi Sato Yoshihiko Kawaguchi Hideki Fujii Kunio Mochizuki Masao Hada Toshio Oyama Tomotaka Yasumura Kosaku Omata Atsushi Nishiyama Keiichi Naito Hideo Hata Yoshiaki Haba Kazuyuki Miyata Haruhisa Saitoh Yoichi Yamadera Kazuo Miura Akira Kawaoi Tohru Abe Hajime Tsunoda Yuji Honda Masayuki Kurosaki Nobuyuki Enomoto | 2015 | World Journal of Gastroenterology2015，21，9： | 8 |
| 3 | Efficient hemostatic method for endoscopic submucosal dissection of colorectal tumors显示文摘AIM:To evaluate a new hemostatic method using hemostatic forceps to prevent perforation and perioperative hemorrhage during colonic endoscopic submucosal dissection(ESD).METHODS:We studied 250 cases,in which ESD for colorectal tumors was performed at the Kyoto Prefectural University of Medicine or Nara City Hospital between 2005 and 2010.We developed a new hemostatic method using hemostatic forceps in December 2008 for the efficient treatment of submucosal thick vessels.ESD was performed on 126 cases after adoption of the new method(the adopted group)and the new method was performed on 102 of these cases.ESD was performed on 124 cases before the adoption of the new method (the unadopted group).The details of the new method are as follows:firstly,a vessel was coagulated using the hemostatic forceps in the soft coagulation mode according to the standard procedure,and the coagulated vessel was removed using the forceps in the'endocut' mode without perioperative hemorrhage.Secondly,the partial surrounding submucosa was dissected using the forceps in the endocut mode.In the current study,we evaluated the efficacy of this method.RESULTS:Coagulated vessels were successfully removed using the hemostatic forceps in all 102 cases without severe perioperative hemorrhage.Moderate perioperative hemorrhage occurred in five cases(4.9%);however,it was stopped by immediately reuse of the hemostatic forceps.The partial surrounding submucosa was dissected using the forceps in all 102 cases.In the adopted group,the median operation time was 105 min.The proportion of endoscopic en bloc resection was 92.8%(P<0.01)compared to 80.6%in the unadopted group.The postoperative hemorrhage and perforation rates were 2.3%and 2.3%.The rate of perforation was significantly lower than that in the unadopted group (9.6%,P<0.01).We evaluated the ease of use of this method by allowing our three trainees to performed ESD on 46 cases,which were accomplished without any severe hemorrhage.CONCLUSION:The new method effectively treated submucosal thick vessels and shows promise for the prevention of perforation and perioperative hemorrhage in colonic ESD. | Naohisa Yoshida Yuji Naito Munehiro Kugai Ken Inoue Naoki Wakabayashi Nobuaki Yagi Akio Yanagisawa Toshikazu Yoshikawa | 2010 | World Journal of Gastroenterology2010，16，33： | 4 |
| 4 | TTYH2,a human homologue of the Drosophila melanogaster gene tweety,is up-regulated in colon carcinoma and involved in cell proliferation and cell aggregation显示文摘AIM: To investigate the expression patterns of TTYH2 in the human colon cancer and colon cancer cell lines and to evaluate the inhibitory effect of small interfering RNA (siRNA) on the expression of TTYH2 in colon cancer cell lines.METHODS: We investigated the expression patterns of TTYH2 in colon cancer, adjacent non-tumorous colon mucosa, and cancer cell lines (DLD-1, caco-2, and Lovo) by RT-PCR. Furthermore, a siRNA plasmid expression vector against TTYH2 was constructed and transfected into DLD-1 and Caco-2 with LipofectamineTM 2000. The down regulation of TTYH2 expression was detected by RT-PCR and the role of siRNA in inducing cell proliferation and cell aggregation was evaluated by MTT and aggregation assay.RESULTS: TTYH2 gene expression in colon cancer tissue was significantly up-regulated compared with normal colonic mucosa (1.23 ± 0.404 vs 0.655 ± 0.373, P = 0.0103). Colon cancer derived cell lines including DLD-1, Caco-2, and Lovo also expressed high levels of TTYH2. In contrast, transfection with siRNA-TTYH2 signifi cantly inhibited both proliferation and scattering of these cancer cell lines.CONCLUSION: The present work demonstrates, for the fi rst time, that the TTYH2 gene expression is signifi cantly up-regulated in colon cancer. The TTYH2 gene may play an important role in regulating both proliferating andmetastatic potentials of colorectal cancer. | Yuji Toiyama Akira Mizoguchi Kazushi Kimura Junichirou Hiro Yasuhiro Inoue Tomonari Tutumi Chikao Miki Masato Kusunoki | 2007 | World Journal of Gastroenterology2007，13，19： | 4 |

| 7 | Highly accurate colorectal cancer prediction model based on Raman spectroscopy using patient serum显示文摘BACKGROUND Colorectal cancer(CRC) is an important disease worldwide, accounting for the second highest number of cancer-related deaths and the third highest number of new cancer cases. The blood test is a simple and minimally invasive diagnostic test. However, there is currently no blood test that can accurately diagnose CRC.AIM To develop a comprehensive, spontaneous, minimally invasive, label-free, bloodbased CRC screening technique based on Raman spectroscopy.METHODS We used Raman spectra recorded using 184 serum samples obtained from patients undergoing colonoscopies. Patients with malignant tumor histories as well as those with cancers in organs other than the large intestine were excluded. Consequently, the specific diseases of 184 patients were CRC(12), rectal neuroendocrine tumor(2), colorectal adenoma(68), colorectal hyperplastic polyp(18), and others(84). We used the 1064-nm wavelength laser for excitation. The power of the laser was set to 200 mW.RESULTS Use of the recorded Raman spectra as training data allowed the construction of a boosted tree CRC prediction model based on machine learning. Therefore, the generalized R^2 values for CRC, adenomas, hyperplastic polyps, and neuroendocrine tumors were 0.9982, 0.9630, 0.9962, and 0.9986, respectively.CONCLUSION For machine learning using Raman spectral data, a highly accurate CRC prediction model with a high R^2 value was constructed. We are currently planning studies to demonstrate the accuracy of this model with a large amount of additional data. | Hiroaki Ito Naoyuki Uragami Tomokazu Miyazaki William Yang Kenji Issha Kai Matsuo Satoshi Kimura Yuji Arai Hiromasa Tokunaga Saiko Okada Machiko Kawamura Noboru Yokoyama Miki Kushima Haruhiro Inoue Takashi Fukagai Yumi Kamijo | 2020 | World Journal of Gastrointestinal Oncology2020，12，11： | 2 |
