Successful treatment of a child with MEK inhibitor-induced acneiform eruption with low-dose isotretinoin

Selumetinib is a mitogen-activated protein kinase/extracellular signal-regulated kinase inhibitor (MEKi) approved to treat inoperable plexiform neurofibromas and used off-label for low-grade gliomas. Acneiform eruptions are a known complication of MEKi use, and in some cases, may lead to paused, dose-reduced, or discontinued therapy. Isotretinoin has been reported as an effective treatment for acneiform eruptions secondary to targeted therapies, primarily in the adult population. Here we describe a pediatric patient with a severe acneiform eruption secondary to selumetinib who was successfully treated with low-dose isotretinoin when unresponsive to conventional therapies.

Efficacy of treatment for acneiform eruptions related to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) for non-small cell lung cancer (NSCLC): A protocol of systematic review and network meta-analysis

BACKGROUND

Acneiform eruptions from epidermal growth factor receptor tyrosine kinase inhibitors is a frequent adverse event in non-small cell lung cancer patients but the efficacy of its treatment including antibiotics, corticosteroid, sunscreen is still poorly understood.

METHODS

Eight electronic databases (PubMed, EMBASE, ClinicalTrials.gov, etc) will be searched from inception to April 2020. Risk of bias of randomized controlled trials will be assessed in terms of the Risk of Bias 2 (RoB 2) tool. Eligible randomized controlled trials will be enrolled for a Bayesian network meta-analysis using R software.

RESULTS

This study is still ongoing and the results will be submitted and published in a peer-reviewed scientific journal.

CONCLUSION

We hope the results of this study will provide reliable evidence for the management of acneiform due to epidermal growth factor receptor tyrosine kinase inhibitors for non-small cell lung cancer.

ETHICS AND DISSEMINATION

Ethical approval is not applicable for this study is based on published trials.
