Prognostic values of treatment modalities on head and neck mucosal melanomas in elderly patients: a population-based analysis.

ABSTRACT:

Background

Head and neck mucosal melanoma (HNMM) is defined as a rare malignant tumor derived from melanocytes. There is no consensus regarding the treatment protocol for HNMM in elderly patients.

Methods

The National Cancer Institute's Surveillance, Epidemiology, and End Results database was used to identify elderly patients diagnosed with HNMM from 1975 to 2016. The chi-squared test was used to compare patient characteristics. The reverse Kaplan-Meier method was used to estimate the median follow-up time. The Kaplan-Meier method and log-rank test were used to estimate and compare the overall survival (OS) and disease-specific survival (DSS) of the groups. Cox regression analysis was used to evaluate the risk factors for OS and DSS of HNMM.
