Biological behavior of the intramucosal Helicobacter pylori-negative undifferentiated-type early gastric cancer: comparison with Helicobacter pylori-positive early gastric cancer
Yusuke Horiuchi,Junko Fujisaki,Noriko Yamamoto,Tomoki Shimizu,Yuji Miyamoto,Hideomi Tomida,Chika Taniguchi,Kenjiro Morishige,Masami Omae,Akiyoshi Ishiyama,Toshiyuki Yoshio,Toshiaki Hirasawa,Yorimasa Yamamoto,Tomohiro Tsuchida,Masahiro Igarashi,Toshifusa Nakajima,Hiroshi Takahashi +16 more
TL;DR: HP+ GC appeared to show a higher proliferative capacity, more extensive spread, and more rapid progression, and inflammation associated with HP infection was suggested to be involved in the proliferation of this type of GC.
Accuracy of diagnostic demarcation of undifferentiated-type early gastric cancers for magnifying endoscopy with narrow-band imaging: endoscopic submucosal dissection cases.
Yusuke Horiuchi,Junko Fujisaki,Noriko Yamamoto,Tomoki Shimizu,Yuji Miyamoto,Hideomi Tomida,Masami Omae,Akiyoshi Ishiyama,Toshiyuki Yoshio,Toshiaki Hirasawa,Yorimasa Yamamoto,Tomohiro Tsuchida,Masahiro Igarashi,Hiroshi Takahashi +13 more
TL;DR: The use of ME-NBI in diagnostic demarcation of UD-type EGCs is recommended and the accurate diagnosis rate was higher for the USS cases with mild neutrophil and monocyte infiltration.
Newly developed magnifying endoscopic classification of the Japan Esophageal Society to identify superficial Barrett’s esophagus-related neoplasms
Kenichi Goda,Junko Fujisaki,Ryu Ishihara,Manabu Takeuchi,Akiko Takahashi,Yasuhiro Takaki,Dai Hirasawa,Kumiko Momma,Yuji Amano,Kazuyoshi Yagi,Hiroto Furuhashi,Tomoki Shimizu,Takashi Kanesaka,Satoru Hashimoto,Yoichiro Ono,Taku Yamagata,Junko Fujiwara,Takane Azumi,Masako Nishikawa,Gen Watanabe,Yasuo Ohkura,Tsuneo Oyama +21 more
TL;DR: The classification has three characteristics: simplified, an easily understood classification by incorporating the diagnostic criteria for the early gastric cancer, including the white zone and demarcation line, and the presence of a modified flat pattern corresponding to non-dysplastic histology by adding novel diagnostic criteria.
Accuracy of diagnostic demarcation of undifferentiated-type early gastric cancer for magnifying endoscopy with narrow-band imaging: surgical cases
Yusuke Horiuchi,Junko Fujisaki,Noriko Yamamoto,Tomoki Shimizu,Masami Omae,Akiyoshi Ishiyama,Toshiyuki Yoshio,Toshiaki Hirasawa,Yorimasa Yamamoto,Tomohiro Tsuchida,Masahiro Igarashi,Hiroshi Takahashi +11 more
TL;DR: The use of ME-NBI in the preoperative diagnosis of the demarcation of cancer is useful to prevent postoperative positive surgical margins.
