    Abstract:
    BACKGROUND: For patients with stage IV nonsmall cell lung cancer (NSCLC) who present with brain metastasis (BMs), standard platinum-based chemotherapy regimens have challenged the role of up-front whole-brain radiotherapy (WBRT). METHODS: In this survey, the authors analyzed the decision tree by which 6 oncologic centers guided the pattern of care in an unselected population of patients with NSCLC who presented with BMs at first diagnosis. The impact of front-line, platinum-based chemotherapy also was evaluated. Individual data were reviewed from 156 eligible patients who were referred to participating centers. RESULTS: Up-front treatment included chemotherapy in 110 patients and WBRT followed by chemotherapy in 46 patients. The selection of first treatment was guided based mainly on the presence of by BM symptoms, with chemotherapy selected for 24% of patients in the chemotherapy cohort and for 76% of patients in the chemotherapy and WBRT cohort. Regardless of treatment, the brain response was 29% (27% and 35% for the chemotherapy and WBRT cohorts, respectively; P value not significant). For the entire population, the overall response rate was 37%, progression-free survival was 6 months, and the median survival was 11 months. At multivariate analysis, significant predictors for survival were: brain response (hazard ratio [HR], 2.59; P = .0001), modified Radiation Therapy Oncology Group class (HR, 0.87; P = .003), and Eastern Cooperative Oncology Group performance status (HR, 1.49; P = .04). CONCLUSIONS: For patients with NSCLC who present with BMs at first diagnosis, the results of the current survey confirmed that the expected benefit of platinum-based chemotherapy may be translated into clinical practice and that selected subsets of patients who receive frontline chemotherapy (ie, patients in whom BM symptoms are absent or are controlled by supportive therapy) may be spared from WBRT. Further prospective studies evaluating different approaches and interventions are warranted.
