Abstract

Objective: Patients with small-cell lung cancer (SCLC) are at high risk of developing brain metastases (BM). Fractionated stereotactic radiotherapy (FSRT) alone or combined with whole brain radiation therapy can be used to treat intracranial metastases. This study was aimed to explore FSRT for BM from SCLC. Materials and Methods: We retrospectively analyzed 45 patients with BM from SCLC treated with fractionated linear accelerator FSRT. Multivariate analysis was used to determine independent risk factors of overall survival (OS). Results: There were 35 patients treated with salvage FSRT and 10 patients treated with primary FSRT. The median OS was 10 months from the beginning of FSRT and 19 months from diagnosis of BM. The median OS of salvage FSRT group and primary FSRT group was 22 and 10 months from the diagnosis of BM, respectively (P = 0.011); 11 and 8 months from FSRT, respectively (P = 0.828). Recursive partitioning analysis class and the stage of the primary tumor were independent predictors of increased OS (relative risk [RR] = 2.634, P = 0.021 and RR = 2.324, P = 0.0210, respectively). Conclusions: Salvage and primary FSRT were both effective treatment options for BM from SCLC. Salvage and primary FSRT may have different OS from the time of diagnosis of BM. [ABSTRACT FROM AUTHOR]
