Outcome Measures
Primary Outcomes (1)
Local tumor control rate (LTCR)
the control rate of treated lesions
3 months after radiation
Secondary Outcomes (5)
Intracranial progression- free survival (IPFS)
up to 1 year
Local recurrence- free survival (LRFS)
up to 1 year
Overall survival (OS)
up to 3 years
Progression- free survival (PFS)
up to 1 year
Brain metastasis-specific survival (BMSS)

Study Arms (2)
CRT group
patients with brain metastases of more than 6 cc and treated with fractionated stereotactic radiotherapy plus concomitant Temozolomide.
RT group
patients with brain metastases of more than 6 cc and treated with fractionated stereotactic radiotherapy alone.
Interventions
The regular prescription doses were 52 Gy in 13 fractions or 52.5 Gy in 15 fractions.
Eligibility Criteria
patients with large brain metastases of more than 6 cc.
You may qualify if:
- (1) primary tumor was pathologically diagnosed and brain metastases were confirmed by gadolinium-enhanced magnetic resonance imaging (MRI) ; (2) age 18 years or older (3) KPS ≥60, or KPS ≥50 but symptomatically caused by BMs; (4) the large lesions haven't treated with surgery or SRT.
You may not qualify if:
- (1) KPS \<60 but not caused by BMs; (2) the large lesions have been treated with surgery or SRT.
