Journal ArticleDOI
Hypofractionated stereotactic radiotherapy (HypoFXSRT) for stage I non-small cell lung cancer: updated results of 257 patients in a Japanese multi-institutional study.
Hiroshi Onishi,Hiroki Shirato,Yasushi Nagata,Masahiro Hiraoka,Masaharu Fujino,Kotaro Gomi,Yuzuru Niibe,Katsuyuki Karasawa,Kazushige Hayakawa,Yoshihiro Takai,Tomoki Kimura,A. Takeda,Atsushi Ouchi,Masato Hareyama,Masaki Kokubo,Ryusuke Hara,Jun Itami,Kazunari Yamada,Tsutomu Araki +18 more
TL;DR: HypoFXSRT with a BED of less than 180 Gy was almost safe for stage I NSCLC, and the local control and overall survival rates in 5 years with a AED of 100 Gy or more were superior to the reported results for conventional radiotherapy.
Journal ArticleDOI
Stereotactic hypofractionated high-dose irradiation for stage I nonsmall cell lung carcinoma: clinical outcomes in 245 subjects in a Japanese multiinstitutional study.
Hiroshi Onishi,Tsutomu Araki,Hiroki Shirato,Yasushi Nagata,Masahiro Hiraoka,Kotaro Gomi,Takashi Yamashita,Yuzuru Niibe,Katsuyuki Karasawa,Kazushige Hayakawa,Yoshihiro Takai,Tomoki Kimura,Yutaka Hirokawa,Atsuya Takeda,Atsushi Ouchi,Masato Hareyama,Masaki Kokubo,Ryusuke Hara,Jun Itami,Kazunari Yamada +19 more
TL;DR: Stereotactic irradiation has been actively performed using various methods to achieve better local control of Stage I nonsmall cell lung carcinoma in Japan and results from a Japanese multiinstitutional study are retrospectively evaluated.
Journal ArticleDOI
Correction: Corrigendum: Cancer cells that survive radiation therapy acquire HIF-1 activity and translocate toward tumour blood vessels
Hiroshi Harada,Masahiro Inoue,Satoshi Itasaka,Kiichi Hirota,Akiyo Morinibu,Kazumi Shinomiya,Lihua Zeng,Guangfei Ou,Yuxi Zhu,Michio Yoshimura,W. Gillies McKenna,Ruth J. Muschel,Masahiro Hiraoka +12 more
TL;DR: Images corresponding to a time point of 16 h were inadvertently used to represent immunohistochemical labelling 3 days after tamoxifen injection and are included in the revised figure below.
Journal ArticleDOI
Clinical outcomes of a phase I/II study of 48 Gy of stereotactic body radiotherapy in 4 fractions for primary lung cancer using a stereotactic body frame
Yasushi Nagata,Kenji Takayama,Yukinori Matsuo,Yoshiki Norihisa,Takashi Mizowaki,Takashi Sakamoto,M. Sakamoto,Michihide Mitsumori,Keiko Shibuya,Norio Araki,Shinsuke Yano,Masahiro Hiraoka +11 more
TL;DR: Forty-eight Gy of 3D stereotactic radiotherapy in 4 fractions using a stereOTactic body frame is useful for the treatment of Stage I lung tumors.
Journal ArticleDOI
Thyroid gland tumor diagnosis at US elastography
Andrej Lyshchik,Tatsuya Higashi,Ryo Asato,Shinzo Tanaka,Juichi Ito,Jerome J. Mai,C. Pellot-Barakat,Michael F. Insana,A. B. Brill,Tsuneo Saga,Masahiro Hiraoka,Kaori Togashi +11 more
TL;DR: Elastography is a promising imaging technique that can assist in the differential diagnosis of thyroid gland cancer, and the usefulness of these criteria was not considered to be high because of their low sensitivity.
