Prognosis of Mucosal Uveal Acral Nonacral Cutaneous and Unknown Primary Melanoma From the Time of First Metastasis

摘要

Background.Subtypes of melanoma, such as mucosal, uveal, and acral, are believed to result in worse prognoses than nonacral cutaneous melanoma. After a diagnosis of distant metastatic disease, however, the overall survival of patients with mucosal, uveal, acral, nonacral cutaneous, and unknown primary melanoma has not been directly compared.
