Malignant Transformation of Endometriosis: Underlying Mechanisms
Endometriotic cyst fluid contains high levels of free iron and oxidative stress products, suggesting the cyst's microenvironment contributes to malignant transformation and clear cell carcinoma development.

The paper examines mechanisms by which ovarian cancer—particularly clear cell and endometrioid carcinoma—can arise from endometriotic cysts, focusing on roles for molecules such as HNF-1β, AKT/PI3K/Met, and ARID1A within an ovarian clear cell carcinoma “signature gene” set. The authors report that these OCCC signature genes include stress-related genes and are induced by endometriotic cyst fluid, which they show contains significantly high free iron and oxidative stress-related products. They infer that the microenvironment of endometriotic cysts may contribute to malignant transformation toward clear cell carcinoma. The chapter caveat is that the precise carcinogenesis mechanism is not fully clarified yet. This paper is centrally about endometriosis — it outlines stress- and iron-driven microenvironmental pathways thought to underlie endometriosis-associated malignant transformation into clear cell ovarian carcinoma.
