Stereotactic ablative radiotherapy with CyberKnife for advanced XXXX : a case report.

@entity1 @entity137 @entity704 @entity5 @entity456
UNASSIGNED: @entity704 is a rare but lethal @entity5 . The optimal treatment for advanced @entity704 is not yet established. This report is the first known of stereotactic ablative radiotherapy (sabr) with CyberKnife (Accuray, Sunnyvale, CA, U.S.A.) as definitive therapy for @entity704 . The @entity1 , a 70-year-old @entity1 with @entity704 , invasion into neighboring organs, and pleural metastases-underwent CyberKnife sabr at 40 Gy in 5 fractions for two lesions, one in the thymus and one in the right paraspinal pleura. After 61 months of observation, a partial response was observed in the irradiated fields. However, disease progression in the non-irradiated pleura was noted. The @entity1 underwent salvage CyberKnife sabr for the four initially nonirradiated @entity456 . Computed tomography images obtained 10 months after the salvage therapy revealed a partial response. The @entity1 is living, with progression-free irradiated lesions and no radiation-related @entity137 . CyberKnife sabr is feasible for @entity1 who are unable to undergo either surgery or conventionally fractionated radiation therapy.
