As systemic immunotherapy offers justification for nodal evaluation, we examined treatment trends among elderly melanoma patients. Patients and Methods: We performed a National Cancer Database analysis of melanoma patients from 2004-2015. Patients were categorized by age (elderly ≥80-years-old). Multivariable logistic regression analyses were performed comparing characteristics and treatment by age. Results: Of 187,814 patients, 2.7% were 1-25, 11.6% were 26-40, 46.6% were 41-64, 28.8% were 65-79, and 10.3% were ≥80-years-old with clinicopathologic and treatment differences between age cohorts. Nodal surgery was least common among elderly patients (43.1% vs. 60.7-69.8%, p<0.0001). For stage III, immunotherapy was least common among the elderly (p<0.0001), but associated with greater survival (HR=0.52, 95%CI=0.32-0.84, p=0.008). Conclusion: Elderly melanoma patients were often treated conservatively, including no nodal evaluation, concerning for the potential undertreatment of this population. ER -
