Makoto Maemondo,Akira Inoue,Kunihiko Kobayashi,Shunichi Sugawara,Satoshi Oizumi,Hiroshi Isobe,Akihiko Gemma,Masao Harada,Hirohisa Yoshizawa,Ichiro Kinoshita,Yuka Fujita,Shoji Okinaga,Haruto Hirano,Kozo Yoshimori,Toshiyuki Harada,Takashi Ogura,Masahiro Ando,Hitoshi Miyazawa,Tomoaki Tanaka,Yasuo Saijo,Koichi Hagiwara,Satoshi Morita,Toshihiro Nukiwa +22 more
TL;DR: First-line gefitinib for patients with advanced non-small-cell lung cancer who were selected on the basis of EGFR mutations improved progression-free survival, with acceptable toxicity, as compared with standard chemotherapy.
Journal ArticleDOI
Updated overall survival results from a randomized phase III trial comparing gefitinib with carboplatin–paclitaxel for chemo-naïve non-small cell lung cancer with sensitive EGFR gene mutations (NEJ002)
Akira Inoue,Kazuhiko Kobayashi,Makoto Maemondo,Shunichi Sugawara,Satoshi Oizumi,Hiroaki Isobe,Akihiko Gemma,Masao Harada,Hirohisa Yoshizawa,Ichiro Kinoshita,Yuka Fujita,Shoji Okinaga,H. Hirano,Kozo Yoshimori,Toshiyuki Harada,Yasuo Saijo,Koichi Hagiwara,Satoshi Morita,Toshihiro Nukiwa +18 more
TL;DR: Considering the many benefits and the risk of missing an opportunity to use the most effective agent for EGFR-mutated NSCLC, the first-line gefitinib is strongly recommended.
Journal ArticleDOI
CD4+ T cells in cancer stroma, not CD8+ T cells in cancer cell nests, are associated with favorable prognosis in human non-small cell lung cancers.
Osamu Wakabayashi,Koichi Yamazaki,Satoshi Oizumi,Fumihiro Hommura,Ichiro Kinoshita,Shigeaki Ogura,Hirotoshi Dosaka-Akita,Masaharu Nishimura +7 more
TL;DR: Investigation of intratumoral tumor‐infiltrating lymphocytes in non‐small cell lung cancers and their relationships with clinicopathological variables and post‐operative survival found higher labeling index of Ki‐67/CD8+ T cells within cancer cell nests is a strong indicator of unfavorable clinical outcome.
Journal ArticleDOI
Factors Related to Diagnostic Yield of Transbronchial Biopsy Using Endobronchial Ultrasonography With a Guide Sheath in Small Peripheral Pulmonary Lesions
Noriyuki Yamada,Koichi Yamazaki,Noriaki Kurimoto,Hajime Asahina,Eiki Kikuchi,Naofumi Shinagawa,Satoshi Oizumi,Masaharu Nishimura +7 more
TL;DR: The position of the probe is a significant factor in predicting the diagnostic yield of TBB using EBUS-GS for small PPLs; the optimum number of biopsy specimens is at least five.
Journal ArticleDOI
Virtual bronchoscopic navigation combined with endobronchial ultrasound to diagnose small peripheral pulmonary lesions: a randomised trial
Takashi Ishida,Fumihiro Asano,Koichi Yamazaki,Naofumi Shinagawa,Satoshi Oizumi,Hiroshi Moriya,Mitsuru Munakata,Masaharu Nishimura +7 more
TL;DR: The diagnostic yield for small peripheral pulmonary lesions is increased when VBN is combined with EBUS, and the only adverse event was mild pneumothorax in a patient from the NVBNA group.
