The elderly with synchronous non-small cell lung cancer and solitary brain metastasis: does palliative thoracic radiotherapy have a useful role?

Abstract

We evaluated the prognosis associated with advanced age by comparing the clinical features of individuals 65 years of age and older to those of younger patients with single metastasis to the brain alone (SMBA) and simultaneous non-small cell lung cancer (NSCLC), and the potential role of palliative thoracic radiotherapy in this cohort of patients. Our 23-year experience included 72 consecutive (22 elderly and 50 non-elderly) people. Older patients predominantly presented with N0-N1 stage disease and coexisting illness. Univariate analysis showed that younger age (p=0.04) and operative removal of SMBA (p=0.01) were predictive of better survival. However, with multivariate analysis, resection of SMBA remained the sole predictor of prognosis. The application of NSCLC radiotherapy for palliation did not favorably alter outcome. In conclusion, elderly patients with simultaneous NSCLC and SMBA seem to fare less well than their younger counterparts. Moreover, the concurrent application of radiotherapy for palliation of the lung neoplasm was not prognostically advantageous.
