OBJECTIVE: The purpose of this study was to investigate cyst fluid levels of total iron, heme iron and free iron in benign endometriotic cysts and endometriosis-associated ovarian cancer (EAOC) and to demonstrate the significance of these biomarkers in differential diagnosis between EAOC and endometriotic cysts. METHODS: Cyst fluid samples were obtained from eleven patients with EAOC and thirty-six women with benign endometriotic cysts at the time of surgery. RESULTS: The median (± SD) total iron levels for endometriotic cysts and EAOC cysts were 244.4 ± 204.9 mg/L and 14.2 ± 36.6 mg/L, respectively. EAOC patients had much lower levels of iron-related compounds compared with endometriotic cyst samples (p< 0.001). When the total iron results were analyzed using the receiver operating characteristics (ROC) curve method, the optimum diagnostic cut-off point was 64.8 mg/L, sensitivity was 90.9%, specificity was 100%, positive predictive value (PPV) was 100%, and negative predictive value (NPV) was 97.3%. Patient demographic characteristics such as tumor size, age at operation, parity and menopause were not correlated with cyst fluid iron levels. CONCLUSIONS: We conclude for the first time that iron-related compounds are important biomarkers that can predict malignant transformation with high sensitivity and specificity for women with endometriosis.
