Arms of the Study
Arm 1
Experimental
Apatinib plus radiotherapy
Apatinib: Within 1 week before radiotherapy, the dose of Apatinib were 500mg/daily .During radiotherapy,the dose of Apatinib were 250mg/daily. After radiotherapy, if the subject did not have a level 3 or above adverse reaction, investigators consider increasing doses to 500mg. Radiotherapy: The subjects with 1 to 4 metastases receive stereotactic radiosurgery or stereotactic radiation therapy ,and the subjects with more than 4 metastases receive stereotactic radiosurgery plus whole-brain radiation therapy.
