研究目的:

卵巢癌发病隐匿,传统常用的超声和肿瘤标志物在其早诊上存在敏感和特异性欠佳的问题。OCS 在诊断卵巢癌的总体敏感性及特异性上表现优秀,有望成为卵巢癌早诊的新方法。若能通过 OCS 甄别出 CA125 轻度升高的附件占位患者中的卵巢癌患者,将极大助益卵巢癌的早诊。但 OCS 对 CA125 轻度升高患者的附件占位的良恶性辨别是否可靠亟待研究。本研究拟通过前瞻性队列研究,检验 OCS 对 CA125 轻度升高患者的附件占位的良恶性辨别能力,为卵巢癌的早诊提供新方案。  

Objectives of Study:

Ovarian cancer is insidious. Traditional ultrasound and tumor markers used in early diagnosis are less sensitive and specific. OCS is effective in diagnosing ovarian cancer, with an overall sensitivity of 95.5% and specificity of 85.5%. It shows promise for early diagnosis. Identifying ovarian cancer patients among those with mildly elevated CA125 and adnexal masses is key to improving early diagnosis. But the reliability of OCS in differentiating the benign and malignant nature of adnexal masses in these patients needs further study. This prospective cohort study will test the ability of OCS to do so, offering a new approach for early diagnosis.
