Rates of ERBB2 Alterations across Melanoma Subtypes and a Complete Response to Trastuzumab Emtansine in an ERBB2-Amplified Acral Melanoma.

ABSTRACT:

Purpose

Patients with BRAF V600 wild-type melanoma whose tumors progress on checkpoint inhibition currently have limited therapeutic options, and additional rational treatment targets are needed. ERBB2 alterations may be amenable to targeted inhibition, but the rate of ERBB2 alterations across melanoma subtypes is not well described.

Patients and methods

All patients with nonuveal melanoma (cutaneous, acral, mucosal, and unknown primary) whose tumors underwent multigene sequencing with MSK-IMPACT at Memorial Sloan Kettering Cancer Center (New York, NY) from 2014 to 2018 were reviewed for known or likely oncogenic somatic alterations in ERBB2 and the other known canonical driver genes BRAF, NRAS, KIT, NF1, GNAQ, and GNA11.
