Abstract:The Veterans Health Administration is the largest integrated health care system in the United States, providing care to over 9 million individuals annually.1 Prior studies have indicated a higher risk of advanced melanoma and melanoma-specific mortality among veterans, but little is known regarding Merkel cell carcinoma (MCC) in the Veterans Affairs (VA) population.2,3 We examined the clinical presentation and disease-specific survival of MCC in the VA Cancer Registry (VACR) compared to the Surveillance, Epidemiology, and End Results (SEER) program.
