National Analysis of Patients With Ulcerated Melanoma in the United States.

Background/Aim: Ulceration is associated with unfavorable prognosis in patients with melanoma. The present study aimed to analyze the characteristics associated with ulcerated melanoma in the United States. It was hypothesized that patient disparities associated with increased odds of ulceration exist. Patients and Methods: We searched the National Cancer Database for melanoma patients from 2004 to 2015. Data regarding patient demographics, facility characteristics, and tumor characteristics were analyzed. Results: There were higher odds of ulceration in non-white patients, 50 years of age or older, and melanoma on the trunk and extremities. Lower odds were found in women, zip codes with higher income and education levels, and Metro or Urban counties. Conclusion: Age above 49 years, male sex, non-white race, living in rural areas, and living in zip codes with low income and low education were independently associated with ulcerated melanoma.
