Management of Dermatologic Complications of Lung Cancer Therapies.

OPINION STATEMENT: In recent years, oncogene-directed targeted agents and immunotherapies have expanded the treatment armamentarium for advanced lung cancer and, in particular, non-small cell lung cancer (NSCLC). Along with extended survival, these agents are accompanied by a host of cutaneous complications that affect the skin, hair, and nails. These skin complications range from the well-characterized papulopustular (acneiform) eruption of the epidermal growth factor receptor (EGFR) inhibitors to the emerging characterization of lichenoid skin eruptions seen during treatment with antibodies targeting the programmed cell death protein 1 (PD-1) and programmed cell death protein 1 ligand (PD-L1). When promptly recognized and accurately diagnosed, most cutaneous adverse events can be managed with supportive treatments, avoiding the need to interrupt antitumor therapy. Furthermore, preemptive management of skin problems can lead to significantly decreased severity of many cutaneous complications of these therapies. We encourage close collaboration between dermatologists and oncologists to better characterize cutaneous toxicity, select appropriate management, and avoid unnecessary dose reduction or discontinuation while simultaneously improving patient quality of life.
