- Abstract
<bold>Background: </bold>Standard treatment for stage III non-small-cell lung cancer (NSCLC) is concurrent chemotherapy and radiation (chemo-RT). However, N3 stage IIIB disease portends a worse prognosis and the tolerability of chemo-RT in patients ≥70 years old is a concern. In this analysis, we evaluate the survival of patients with N3 stage IIIB NSCLC who were treated with chemo-RT or chemotherapy alone with a focus on elderly patients.<bold>Patients and Methods: </bold>We retrospectively analyzed patients diagnosed with N3 stage IIIB NSCLC between 2010 and 2013 using the National Cancer Database. We compared overall survival (OS) between patients who underwent chemo-RT versus chemotherapy alone. The Kaplan-Meier method was used for median OS with log rank tests. Multivariable Cox models were used for multivariable and subgroup analyses.<bold>Results: </bold>We included 9769 patients in our analysis, 7770 of whom received chemo-RT and 1999 who received chemotherapy alone. The median OS for patients who received chemo-RT was 16.4 months versus 12.7 months with chemotherapy alone (P < .0001). The median OS for patients ≥70 years old who received chemo-RT was 15.0 months versus 12.4 months with chemotherapy alone (P < .0001). In multivariable analyses, the benefit of chemo-RT was similar regardless of age. Subgroup analyses in patients ≥70 years indicated a benefit of chemo-RT (hazard ratio, <1.0) across all patient and disease strata.<bold>Conclusion: </bold>Survival was improved in elderly patients who received chemo-RT versus chemotherapy alone for N3 stage IIIB NSCLC. Our findings suggest that age and comorbidities should not preclude clinicians from recommending chemo-RT to these patients.
