Clinical Trial Summary

The treatment of the patients with metastatic breast cancer remains a major problem. However, there is an intermediate state between the primary tumor and distant metastases called oligometastasis. Current research indicates that good local control of oligometastasis can be obtained with Stereotactic body radiotherapy (SBRT) Can not prolong the long-term survival of patients. Researchers believe that after SBRT treatment of patients with oligometacosis in breast cancer, it is necessary to explore whether the anti-angiogenic therapy targeted drug apatinib can reduce the occurrence of new lesions and prolong the survival of patients.


Clinical Trial Description

The treatment of the patients with metastatic breast cancer remains a major problem. However, there is an intermediate state between the primary tumor and distant metastases called oligometastasis. Current research indicates that good local control of oligometastasis can be obtained with Stereotactic body radiotherapy (SBRT) Can not prolong the long-term survival of patients. Researchers believe that after SBRT treatment of patients with oligometacosis in breast cancer. So, through the detection of microRNA in the primary lesion of breast cancer patients with oligometastasis to screen the patients with oligomerization and potential multiple metastases; explore the existing medical treatment, based on the control of local lesions by SBRT, the use of apatinib anti-angiogenic targeted maintenance therapy, with a view to reducing the incidence of new lesions, thereby prolonging the patient's survival. ;
