Abstract： Objective Evaluation the Fractionated Stereotactic Radiotherapy (FSRT) for the patients with small-cell lung cancer (SCLC) after the whole brain radiotherapy (WBRT) failure.Methods We retrospectively analyzed 35 patients with brain metastases from small-cell lung cancer treated with linear accelerator FSRT after the WBRT failure. Multivariate analysis was used to determine significant prognostic factor related to survival.Results The following-up rate was 100％.The median following-up time was 11 months.The median over-all survival (OS) time was 10.3( 1 -30) months after FSRT.Controlled extra cranial disease was the only identified significant predictor of increased median OS time (χ2 =4.02,P =0.045 ).The median OS time from the diagnosis of brain metastasis was 22 (6 - 134 )months.14 patients died from brain metastasis,14 from extra-cranial progression,1 from leptomeningeal metastases,and 3 from other causes. Local control at 6 months and 12 months was 91％ and 76％,respectively.No significant late complications.New brain metastases outside of the treated area developed in 17％ of patients at a median time of 4(2 -20) months; all patients had received previous WBRT.Conclusions Fractionated stereotactic radiotherapy was safe and effective treatment for recurrent small-cell lung carcinoma brain metastases.
