PURPOSE: This pooled analysis was undertaken to assess the efficacy and toxicity of adjuvant cisplatin-based chemotherapy in elderly patients with non-small-cell lung cancer (NSCLC). METHODS: We used individual patient data from 4,584 patients enrolled onto five trials of cisplatin-based chemotherapy who form the basis for the Lung Adjuvant Cisplatin Analysis (LACE) pooled analysis. Patient and treatment characteristics, overall and event-free survival, cause-specific mortality, chemotherapy toxicity and delivery were compared among three age groups: 3,269 young (71%; < 65), 901 midcategory (20%; 65 to 69), and 414 elderly patients (9%; >or= 70). Log-rank tests stratified by trials were used with a test for trend to study the effect of chemotherapy on survival according to age. RESULTS: The hazard ratio (HR) of death for the young patients was 0.86 (95% CI, 0.78 to 0.94), 1.01 for the midcategory (95% CI, 0.85 to 1.21), and 0.90 for elderly patients (95% CI, 0.70 to 1.16; test for trend: P = .29). The HR for event-free survival was 0.82 for young (95% CI, 0.75 to 0.90), 0.90 for the midcategory (95% CI, 0.76 to 1.06), and 0.87 for elderly patients (95% CI, 0.68 to 1.11; test for trend: P = .42). More elderly patients died from non-lung cancer-related causes (12% young, 19% midcategory, 22% elderly; P < .0001). No differences in severe toxicity rates were observed. Elderly patients received significantly lower first and total cisplatin doses, and fewer chemotherapy cycles (chi(2) P < .0001). CONCLUSION: Adjuvant cisplatin-based chemotherapy should not be withheld from elderly patients with NSCLC purely on the basis of age.
