The Compatibility of Pathological Findings of Ovarian Cysts with Preoperative Ultrasound Findings

Background & Objective: Ovarian cysts are common findings in gynecological practice and are often detected incidentally through imaging, particularly ultrasound. This study was conducted with aim to evaluate the compatibility between preoperative ultrasound findings and final pathological diagnoses of ovarian.Materials & Methods: This study was conducted on the medical records of ۱۰۰ patients who underwent surgical intervention for ovarian cysts in ۲۰۲۰ at Forghani Hospital, Qom, Iran. Variables included patient demographics, cyst characteristics (size, morphology, solid components, septations, Doppler vascularity), tumor markers (AFP, LDH, CA۱۲۵, CEA, HE۴, CA۱۹.۹), ultrasound impressions (benign vs. suspicious), and histopathological diagnoses. Statistical analysis was performed using SPSS software (version ۲۶), and agreement between ultrasound and histopathology was assessed via the Kappa statistic and categorical variables compared using the Chi-square test. P<۰.۰۵ was considered significant.  Results: Pathological diagnoses revealed ۹۴% of cysts as benign lesions (۲۸% functional cysts, ۳۰% serous cysts, ۱۸% dermoids, ۱۸% endometriomas) and ۶% malignant lesions. Ultrasound classified ۴۵% of cysts as "benign" and ۵۵% as "suspicious." A significant correlation was found between ultrasound impressions and pathology diagnosis (P<۰.۰۰۱). For malignancy detection, ultrasound demonstrated moderate sensitivity (۵۰%), low specificity (۴۴.۷%), low positive predictive value (PPV: ۵.۵%), and high negative predictive value (NPV: ۹۳.۳%). Tumor markers showed elevated CA۱۲۵ (۴۲%) and HE۴ (۳۹%) in benign cases, highlighting limited specificity.  Conclusion: Ultrasound effectively excludes benign ovarian cysts (high NPV) but poorly detects malignancy (low PPV). Integrated diagnostic approaches combining standardized systems, tumor markers, and advanced imaging are essential to improve risk assessment and avoid overtreatment.
