Pruritus Associated with Targeted Anticancer Therapies and Their Management

Abstract

Targeted anticancer therapies have significantly increased the survival of patients with a variety of malignancies, improving tolerability and treatment duration. The increased lifespan and the expanded use of targeted agents have led to a variety of treatment-related adverse events. Pruritus, a common dermatologic adverse event with various incidences ranging from 2.2% to 47% across different categories of targeted anticancer therapies, has been overlooked. This article reviews the incidence, accompanying skin conditions, possible pathomechanism, and proposed management algorithms of pruritus associated with targeted therapies, including immunotherapies.
