Abstract

Abstract : Adenoid cystic carcinoma of the lacrimal gland is an aggressive, malignant epithelial neoplasm. We report the case of a 30-year-old male with lacrimal gland adenoid cystic carcinoma treated with neoadjuvant intra-arterial chemotherapy through the internal carotid artery, followed by orbital exenteration and chemoradiation. Treatment response was evaluated using a novel combination of pre- and posttreatment genome sequencing coupled with immunohistochemical evaluation, which showed diffuse tumor apoptosis. A posttreatment decrease in variant allele frequency of the NOTCH1 mutation, and robust tumor cytoreduction on imaging, supports exploration of NOTCH1 analysis as a potential marker of cisplatin sensitivity. The use of genome sequencing and immunohistochemical evaluation could provide a more targeted therapeutic assessment of neoadjuvant intra-arterial chemotherapy in the management of lacrimal gland adenoid cystic carcinoma.

Treatment response was evaluated using pre- and post-treatment genome sequencing and immunohistochemical analysis with tumor apoptosis markers.
