Frontiers in the Pathology and Pathogenesis of Ovarian Cancer: Cancer Precursors and "Precursor Escape"

Hematol Oncol Clin North Am. 2018 Dec;32(6):915-928. doi: 10.1016/j.hoc.2018.07.013.

Abstract

This article summarizes the pathogenesis of ovarian carcinoma, focusing on the paradox of high-grade serous carcinogenesis. The fallopian tube is the prime site of origin in early serous cancers. Because a subset of serous cancers is associated with early serous proliferations absent intramucosal carcinomas, "precursor escape" is emerging, whereby some advanced cancers trace their roots to early serous proliferations. This has parallels in the endometriosis model and opens up a novel mechanism by which advanced malignancy could emerge without an obvious tubal carcinoma. The impact of this concept on classification of serous cancer and expectations from preventive strategies are discussed.

Keywords: Endometriosis; High-grade serous carcinoma; Precursor escape; Serous tubal intraepithelial carcinoma; Serous tubal intraepithelial lesion.
