Computed tomography-guided frameless stereotactic radiotherapy for stage I non-small cell lung cancer: a 5-year experience

Autor: Yukihiro Hama, Yuichi Ozeki, Akira Shioda, J. Wong, Minoru Uematsu, Toshiharu Fukui, Shoichi Kusano, Atsushi Suda

Publikováno v: International journal of radiation oncology, biology, physics. 51(3)

Purpose: Stereotactic radiotherapy (SRT) is highly effective for brain metastases from non-small-cell lung cancers (NSCLCs). As such, primary lesions of NSCLC may also be treated effectively by similar focal high-dose SRT. Methods and Materials: Betw
