TL;DR: The role of exosomes in intercellular communication between cancer cells following radiation exposure is unclear as mentioned in this paper, however, the exact mechanism of the interaction between cells and neighboring cancer cells is unclear.
Journal ArticleDOI
Pattern of recurrence after CyberKnife stereotactic body radiotherapy for peripheral early non-small cell lung cancer
Masaki Nakamura,Ryo Nishikawa,Hiroshi Mayahara,Haruka Uezono,Aya Harada,Naoki Hashimoto,Hideki Nishimura +6 more
TL;DR: Treatment efficacy after CyberKnife S BRT for peripheral early-stage NSCLC was identical to previous conventional linac-based SBRT reports, and GTV and DTI were the significant predictive factor of infield recurrence, and EGFR mutation was the significant predicting factor of out-of-field recurrence.
Journal ArticleDOI
Radiotherapy for brainstem gliomas in children and adults: A single-institution experience and literature review.
Kenji Yoshida,Nor Shazrina Sulaiman,Daisuke Miyawaki,Yasuo Ejima,Hideki Nishimura,Takeaki Ishihara,Yoshiro Matsuo,Ryo Nishikawa,Takashi Sasayama,Akira Hayakawa,Eiji Kohmura,Ryohei Sasaki +11 more
TL;DR: To evaluate the treatment results of radiotherapy (RT) in children and adults with brainstem gliomas (BSGs) and review the previous literature, radiotherapy is evaluated as a single therapy in patients with BSOs.
Journal ArticleDOI
Investigation of the efficacy and safety of CyberKnife hypofractionated stereotactic radiotherapy for brainstem metastases using a new evaluation criterion: 'symptomatic control'.
Masaki Nakamura,Hideki Nishimura,Hiroshi Mayahara,Haruka Uezono,Aya Harada,Naoki Hashimoto,Yasuo Ejima,Takeaki Ishihara,Ryo Nishikawa,Ryohei Sasaki +9 more
TL;DR: This study investigates the efficacy and safety of CyberKnife hypofractionated stereotactic radiotherapy for brainstem metastases and proposes a new evaluation criterion—‘symptomatic control’—to evaluate the efficacyand safety of brainstem radiotherapy.
Journal ArticleDOI
Additional chemotherapy improved local control and overall survival after stereotactic body radiation therapy for patients with oligo-recurrence
Masaki Nakamura,Naoki Hashimoto,Hiroshi Mayahara,Haruka Uezono,Aya Harada,Ryo Nishikawa,Yoshiro Matsuo,Hiroki Kawaguchi,Hideki Nishimura +8 more
TL;DR: SBRT is a safe and effective treatment for patients with lung and liver oligo-recurrence and among colorectal cancer patients, additional chemotherapy after SBRT significantly associated better OS.
