This paper is a review focused on ovarian clear cell carcinoma (OCCC), particularly how oxidative stress influences carcinogenesis from endometriosis and how oxidative-stress–tolerant features affect survival and treatment resistance in advanced or recurrent disease. It summarizes that the oxidative stress in OCCCs can be divided into two categories: transformation from endometriosis to OCCC and factors related to treatment after malignant transformation, with antioxidants potentially reducing formation risk by quenching reactive oxygen species while resistance mechanisms support established cancer cells. The review further links oxidative stress resistance to cancer stemness and discusses post-refractory treatment challenges, noting that therapeutic approaches still need improvement and proposing multi-combinatorial strategies, including nucleic acid-based drugs targeting transcriptional profiles. This paper is centrally about endometriosis — it explains how OCCC often arises from endometriosis under strong oxidative stress and is linked to cancer development and treatment after that transformation.

Abstract

Ovarian clear cell carcinomas (OCCCs) are resistant to conventional anti-cancer drugs; moreover, the prognoses of advanced or recurrent patients are extremely poor. OCCCs often arise from endometriosis associated with strong oxidative stress. Of note, the stress involved in OCCCs can be divided into the following two categories: (a) carcinogenesis from endometriosis to OCCC and (b) factors related to treatment after carcinogenesis. Antioxidants can reduce the risk of OCCC formation by quenching reactive oxygen species (ROS); however, the oxidant stress-tolerant properties assist in the survival of OCCC cells when the malignant transformation has already occurred. Moreover, the acquisition of oxidative stress resistance is also involved in the cancer stemness of OCCC. This review summarizes the recent advances in the process and prevention of carcinogenesis, the characteristic nature of tumors, and the treatment of post-refractory OCCCs, which are highly linked to oxidative stress. Although therapeutic approaches should still be improved against OCCCs, multi-combinatorial treatments including nucleic acid-based drugs directed to the transcriptional profile of each OCCC are expected to improve the outcomes of patients.
