Analysis of stereotatic radiotherapy for brain metastases

Objective To investigate the effect of stereotatic radiotherapy (SRT) for brain metastases. Methods Retrospect compare 66 patients treated by SRT with whole brain radiotherapy (WBRT+ SRT) to 26 patients treated by SRT alone, Results The patients treated by WBRT+ SRT had significantly benefit in lesions recurrence (13,3% vs 42.2%), middle recurrence time (10.5 months vs 4.2 months) and middle survival time(13 months vs 6.5 months) over the patients treated by SRT, respectively (P<0.05), But there are no different in terms of improving of Karnofsky score, effective rate, one-year survival rate, one-year death rate between the two groups. Conclusion WBRT+ SRT play an important role in treating brain metastases, by improving patients' life quantity and reducing recurrence.
