We aimed to describe the factors and survival related to the presence of residual tumor in patients with invasive melanoma lymph nodes negative. Patients and Methods: We performed a retrospective study by querying the National Cancer Database from 2004 to 2015. Associations were tested using a multivariate analysis. Overall survival was compared using the Kaplan-Meier method. Results: A total of 26,440 patients met the inclusion criteria. For Breslow depth groups ≤1 mm and >2 mm, older age and location in the head and neck were factors associated to residual tumor in margins (p<0.05), whereas only location in the head and neck was associated to residual tumor for patients with Breslow depth between 1.01-2.00 mm (p<0.05). Conclusion: Knowledge of the factors associated with the residual tumor will help establish a patient-centered management and decrease the recurrence of disease. ER -
