Abstract:
OBJECTIVETo evaluate the efficacy, survival and toxicity in patients with brain metastases from non-small cell lung cancer (NSCLC), treated with concurrent systemic chemotherapy and whole brain radiation therapy (WBRT) or sequential systemic chemotherapy/WBRT.
METHODSA total of 60 NSCLC patients with brain metastases were divided into two groups in this prospective clinical study: concurrent systemic chemotherapy and WBRT group (concurrent group) and sequential systemic chemotherapy/WBRT group (sequential group).
RESULTSOf 59 assessable patients, the overall response rate was 22.0%, and the brain response rate was 35.6%; the median progression-free survival time was 3.0 months, and the overall 1- and 2-year survival rates were 55% and 24.4%, respectively, with a median survival time of 16.0 months. The overall response rate was 20.0% in the concurrent group and 24.1% in sequential group (P > 0.05). The brain response rates of 43.3% in concurrent group and 27.6% in sequential group were also not significantly different (P > 0.05). The median progression-free survival time for the patients in the concurrent group was 3.0 months versus 4.0 months in the sequential group, and the median survival time was 16.0 months versus 13.0 months (all P > 0.05). The 1- and 2-year survival rates were 58.5% and 37.2% versus 52.9% and 18.9%, respectively, with a significant difference in the 2-year survival rate between the two groups (P = 0.011). In the sequential group, leukopenia was more frequent during chemotherapy than that in the concurrent group (P = 0.029).
CONCLUSIONConcurrent systemic chemotherapy and WBRT is effective with tolerable adverse events in treating brain metastasis from NSCLC with an encouraging survival, and deserves further large sample and randomized multicenter clinical trials.
