Is there a role for tumor necrosis factor-alpha inhibitors and especially thalidomide in dermatology?

Cutaneous reactions related to systemic immunomodulators and targeted therapeutics

The arrival of targeted therapeutics into the oncology clinic, while enthusiastically anticipated, introduced the oncologist to dermatologic events that can pose challenging management issues. The dermatologic effects of these targeted agents appear to be more frequent than those with cytotoxic therapy and are not uniform; that is, different agents have distinct dermatologic toxicities. Interestingly, dermatologic toxicity may correlate with antitumor activity with some of these targeted agents. The correlation of rash with response and survival in particular mandates the development of effective and appropriate management strategies. The nature and challenges of the dermatologic events observed to date with epidermal growth factor receptor inhibitors, multikinase inhibitors, proteosome inhibitors, BCR-ABL tyrosine kinase inhibitors, and immunomodulatory drugs will be addressed in this review.
