Epithelial ovarian cancer is the most prevalent gynecological malignancy, characterized by high mortality rates due to its late-stage diagnosis and frequent recurrence. The current standard of care for ovarian cancer is a combination of debulking surgery followed by the conventional mode of chemotherapy. Despite significant advances in therapeutic modalities, the overall survival rate of EOC continues to be poor, mainly because low concentrations of the chemotherapeutics reach the peritoneum, which is the primary site of ovarian cancer, leading to disease relapse.

Leukemia is one of the most common cancers in prepubertal girls and adolescents, with advances improving survival rates. However, treatments like chemotherapy and radiation are highly gonadotoxic, often causing ovarian insufficiency, early menopause, infertility, and endocrine disorders. Fertility preservation for young female cancer patients, especially prepubertal girls without mature germ cells, relies heavily on ovarian tissue cryopreservation.

Cancer cells cope with oxidative stress for their proliferation and metastasis by equipping antioxidant systems, among which the antioxidant enzymes peroxiredoxins (PRDXs) play crucial roles. However, whether PRDXs exhibit nonenzymatic functions remains unclear. Here, it is shown that the 1-cysteine PRDX (PRDX6) upregulates nicotinamide N-methyltransferase (NNMT) to promote the growth and metastasis of ovarian cancer cells, independently of PRDX6's enzymatic activities.

Objective: Gonadal dysfunction is a major late complication after cancer diagnosis and treatment. We aimed to study the prevalence of premature ovarian insufficiency (POI) and the potential reduction of ovarian reserve in a cohort of adolescent and young adult (AYA) patients undergoing cancer treatments, evaluating ovarian function and reserve markers. We also aimed to analyze how these markers are related to each other and to treatment-related risk factors.
