Abstract
Using immunohistochemistry, we examined a large cohort of 135 ovarian tumors, made up of 96 low-grade serous carcinomas (LGSCs) and 39 serous borderline tumors (micropapillary variant, mSBT), with the aim of exploring their HER2 status (overexpression). We followed with comprehensive genomic analyses on this sample set from our previous study, which revealed HER2 mutation in 5% (4/75) of LGSC and 10% (3/29) of mSBT. No cases were evaluated as HER2-positive, but 6 LGSCs and 1 mSBT were scored as HER2 1+, and 2 LGSCs and 1 mSBT showed the so-called HER2 "ultra-low" phenotype. This could be of clinical value as a potential therapeutical target concerning emerging therapeutic treatments (antibody conjugates). However, the clinical significance of this expression still needs to be established.
期刊介绍：
International Journal of Gynecological Pathology is the official journal of the International Society of Gynecological Pathologists (ISGyP), and provides complete and timely coverage of advances in the understanding and management of gynecological disease. Emphasis is placed on investigations in the field of anatomic pathology. Articles devoted to experimental or animal pathology clearly relevant to an understanding of human disease are published, as are pathological and clinicopathological studies and individual case reports that offer new insights.
