Journal ArticleDOI

TL;DR: ITPNs can be considered to represent a new disease entity encompassing intraductal tubular carcinoma as a morphologic variant as well as several features of acinar cell carcinoma, except for the tubulopapillary growth pattern.
Journal ArticleDOI
Pathways of Progression From Intraductal Papillary Mucinous Neoplasm to Pancreatic Ductal Adenocarcinoma Based on Molecular Features

TL;DR: Detailed histologic and genetic analysis of PDAs and concurrent IPMNs identified 3 different pathways by which IPMNs progress to PDAs-the authors call these the sequential, branch-off, and de novo subtypes.
Journal ArticleDOI
Somatic mutations in PIK3CA and activation of AKT in intraductal tubulopapillary neoplasms of the pancreas.
Hiroshi Yamaguchi,Yuko Kuboki,Takashi Hatori,Masakazu Yamamoto,Keiko Shiratori,Shunji Kawamura,Makio Kobayashi,Michio Shimizu,Shinichi Ban,Isamu Koyama,Morihiro Higashi,Nobuhiro Shin,Kazuyuki Ishida,Takanori Morikawa,Fuyuhiko Motoi,Michiaki Unno,Atsushi Kanno,Kennichi Satoh,Tooru Shimosegawa,Hideki Orikasa,Tomoo Watanabe,Kazuhiko Nishimura,Youji Harada,Toru Furukawa +23 more
TL;DR: Results indicate that activation of the phosphatidylinositol 3-kinase pathway may play a crucial role in ITPNs but not in IPMNs, and the activated phosphorylated AKT pathway may be a potential target for molecular diagnosis and therapy of I TPNs.
Journal ArticleDOI
Whole exome sequencing reveals recurrent mutations in BRCA2 and FAT genes in acinar cell carcinomas of the pancreas
Toru Furukawa,Hitomi Sakamoto,Shoko Takeuchi,Mitra Ameri,Yuko Kuboki,Toshiyuki Yamamoto,Takashi Hatori,Masakazu Yamamoto,Masanori Sugiyama,Nobuyuki Ohike,Hiroshi Yamaguchi,Michio Shimizu,Noriyuki Shibata,Kyoko Shimizu,Keiko Shiratori +14 more
TL;DR: Assessment of BRCA2 abrogation in patients with the carcinoma to determine their sensitivity to chemotherapy is warranted, as acinar cell carcinomas show a distinct mutation pattern and often harbor somatic or germline mutations of BrcA2 and FAT genes.
Journal ArticleDOI
Chlamydia pneumoniae: comparison with findings of Mycoplasma pneumoniae and Streptococcus pneumoniae at thin-section CT.
Atsushi Nambu,Akitoshi Saito,Tsutomu Araki,Katsura Ozawa,Yoshimitsu Hiejima,Masaki Akao,Zennosuke Ohki,Hiroshi Yamaguchi +7 more
TL;DR: C pneumoniae pneumonia demonstrates a wide spectrum of thin-section CT findings that are similar to those of S pneumoniaeneumon pneumonia and M pneumoniaE pneumonia; airway dilatation and bronchovascular thickening were significantly more frequent in patients with C pneumoniaes pneumonia.
