Journal ArticleDOI
Peripheral lung adenocarcinoma: Correlation of thin-section CT findings with histologic prognostic factors and survival
Takatoshi Aoki,Yoshinori Tomoda,Hideyuki Watanabe,Hajime Nakata,Takahiko Kasai,Hiroshi Hashimoto,Mantaro Kodate,Toshihiro Osaki,Kosei Yasumoto +8 more
TL;DR: Thin-section CT findings of peripheral lung adenocarcinomas correlate well with histologic prognostic factors and showed a significantly better prognosis than those with GGO components less than 50%.
Journal ArticleDOI
Evolution of peripheral lung adenocarcinomas: CT findings correlated with histology and tumor doubling time.
Takatoshi Aoki,Hajime Nakata,Hideyuki Watanabe,Koji Nakamura,Takahiko Kasai,Hiroshi Hashimoto,Kosei Yasumoto,Masamitsu Kido +7 more
TL;DR: Two main types of peripheral lung adenocarcinoma exist: the first appears on CT as a localized ground-glass opacity with slow growth, and the other appears as a solid attenuation with rapid growth.
Journal ArticleDOI
The diagnosis of mild emphysema. Correlation of computed tomography and pathology scores.
Kazuyoshi Kuwano,Kenichi Matsuba,T Ikeda,Junji Murakami,Akiteru Araki,Hiromu Nishitani,Teruyoshi Ishida,Kosei Yasumoto,Nobuaki Shigematsu +8 more
TL;DR: It is concluded that high resolution CT can help to identify the presence and grading of mild emphysema.
Journal ArticleDOI
Hepatocyte growth factor expression in EGFR mutant lung cancer with intrinsic and acquired resistance to tyrosine kinase inhibitors in a Japanese cohort.
Seiji Yano,Tadaaki Yamada,Shinji Takeuchi,Keisei Tachibana,Yuko Minami,Yasushi Yatabe,Tetsuya Mitsudomi,Hidenori Tanaka,Tatsuo Kimura,Shinzoh Kudoh,Hiroshi Nokihara,Yuichiro Ohe,Jun Yokota,Hidetaka Uramoto,Kosei Yasumoto,Katsuyuki Kiura,Masahiko Higashiyama,Makoto Oda,Haruhiro Saito,Junji Yoshida,Kazuya Kondoh,Masayuki Noguchi +21 more
TL;DR: High-level HGF expression was detected more frequently than EGFR T790M secondary mutation or MET amplification in tumors with intrinsic and acquired EGFR-TKI resistance in EGFR mutant lung cancer in Japanese patients.
Journal ArticleDOI

Satoshi Morita,Isamu Okamoto,Kunihiko Kobayashi,Koichi Yamazaki,Hajime Asahina,Akira Inoue,Koichi Hagiwara,Noriaki Sunaga,Noriko Yanagitani,Toyoaki Hida,Kimihide Yoshida,Tomonori Hirashima,Kosei Yasumoto,Kenji Sugio,Tetsuya Mitsudomi,Masahiro Fukuoka,Toshihiro Nukiwa +16 more
TL;DR: Gefitinib monotherapy confers substantial clinical benefit in terms of progression-free survival and overall survival in non–small cell lung cancer patients with EGFR mutations.
