Surgical Management and Prognostic Factors in Patients with Subungual Melanoma

Abstract

The study identified several significant prognostic factors, including DNA flow cytometric parameters, in patients with subungual melanoma. In addition, it showed that conservative amputation of the affected digit at the level of the proximal interphalangeal or metacarpophalangeal/metatarsophalangeal joint appears to be safe, provided that clear margins are obtained. Although isolated limb perfusion may reduce the incidence of local recurrence, LND, or limb perfusion in the routine management of subungual melanoma remains controversial.
