BACKGROUND: Brain metastases (BMs) are found in about 10% of patients with newly diagnosed non-small cell lung cancer (NSCLC). This retrospective study was conducted to assess the clinical outcomes and prognostic factors of patients who received chemotherapy after cranial irradiation for NSCLC with synchronous BMs. MATERIALS AND METHODS: From January 2000 through July 2007, we reviewed the medical records of patients who received systemic chemotherapy following cranial irradiation for BMs from newly diagnosed NSCLC. RESULTS: A total of 40 patients were included in this review. As the first-line chemotherapy, a total of 114 cycles were administered, for a median number of 2 cycles per patient (range, 0.5-8 cycles). Thirty-four patients (85%) received platinum-based combination regimen and the remaining 6 received chemotherapy with a single agent. Sixteen (40%) patients, 11 of whom had ECOG of 2, only received 1 cycle or less of chemotherapy due to early death, rapid progression, clinical impairment, or toxicity. For 28 patients who were evaluable for response, the extracranial overall response rate was 43%. The median overall survival for all patients was 7 months (range, 0.9-25.3 months) and an estimated 1-year survival rate was 23%. Multivariate analysis revealed that ECOG status (P=0.018) and number of BM (P=0.038) were independent prognostic factors. CONCLUSION: Our results suggest that chemotherapy can be used to increase survival of patients treated with cranial irradiation for newly diagnosed NSCLC with synchronous BM. However, systemic chemotherapy should be carefully considered according to the patient's prognostic condition. Especially, patients with good performance status and limited number of BM may be good candidates for systemic chemotherapy after cranial irradiation.
