Primary mucosal melanoma (MM) is an aggressive cancer arising from the uncontrolled proliferation of melanocytes located in the mucosal membrane. Compared to cutaneous melanoma, primary MM is far rarer but carries a poorer prognosis. Bishop and OlszewskiThe Surveillance, Epidemiology, and End Results (SEER) database contains information about the incidence and prognosis of various cancers and has become a good way to investigate rare tumors such as PGIM. Studies of PGIM based on the SEER database including the epidemiology, therapy, and prognosis have been published.
