Histone deacetylase inhibitor for NUT midline carcinoma.

ABSTRACT

NUT Midline carcinoma (NMC) is a rare and invariably fatal poorly differentiated carcinoma characterized by chromosomal rearrangement involving the nuclear protein of the testis (NUT) gene. Current approaches do not provide durable response. We report a case of widely metastatic NMC in a 17-year-old female who, following an initial response to combination chemotherapy developed rapid disease progression. Treatment with vorinostat, a histone deacetylase inhibitor (HDACi) resulted in an objective response, yet she died in less than one year from initial diagnosis. This report shows a potentially promising activity of HDACi in the treatment of NMC that needs further exploration.
