Abstract

Cancer Antigen 125 (CA125) and Human Epididymis Protein 4 (HE4) are the most studied ovarian tumor markers. Their diagnostic performance for identification of ovarian cancer are superior to CA19-9, CA72-4, and carcinoembryonic antigen, which are no more recommended for the diagnosis of presumed benign ovarian tumor. HE4 (>140 pmol/L) is superior to CA125 (>30 U/mL) in terms of specificity and positive likelihood ratio. CA125 and HE4 can be combined into an algorithm ROMA, or associated to clinical information (composite index), biological data (OVA1) or imaging (Risk for Malignancy Index (RMI), LR2). ROMA algorithm is an exponential equation combining plasmatic concentrations of HE4 and CA125. ROMA is more sensitive and less specific than HE4 in predicting epithelial ovarian cancer. ROMA is more accurate in post-menopausal women. The performance of ROMA is lower than the ultrasound model LR2 in differentiating malignant from benign ovarian tumors, whatever the hormonal status. The composite index combining CA125 with a symptoms index (pain, abdominal distension, bloating, difficulty eating) has a good sensitivity in a screening program, but because of a 12% false positive rate, ultrasound is required before management. The RMI algorithm is based on serum CA125, ultrasound findings (septation, solid zones, metastases, ascite, bilaterality) and menopausal status. RMI is less sensitive, but more specific than ROMA or OVA1 for the classification of ovarian masses. The addition of HE4 to RMI seems to be the most accurate. The subjective evaluation of ovarian cysts by sonography and color Doppler is better than ROMA and RMI algorithms, and not affected by the hormonal status.

摘要

癌抗原125(CA125)和人附睾蛋白4(HE4)是研究最多的卵巢肿瘤标志物。它们在识别卵巢癌方面的诊断性能优于CA19-9、CA72-4和癌胚抗原,后三者不再推荐用于诊断疑似良性卵巢肿瘤。在特异性和阳性似然比方面,HE4(>140 pmol/L)优于CA125(>30 U/mL)。CA125和HE4可组合成ROMA算法,或与临床信息(综合指数)、生物学数据(OVA1)或影像学(恶性风险指数(RMI)、LR2)相关联。ROMA算法是一个结合HE4和CA125血浆浓度的指数方程。ROMA在预测上皮性卵巢癌方面比HE4更敏感但特异性更低。ROMA在绝经后女性中更准确。无论激素状态如何,ROMA在区分卵巢恶性肿瘤和良性肿瘤方面的性能低于超声模型LR2。将CA125与症状指数(疼痛、腹胀、腹部膨隆、进食困难)相结合的综合指数在筛查项目中具有良好的敏感性,但由于假阳性率为12%,在处理前需要进行超声检查。RMI算法基于血清CA125、超声检查结果(分隔、实性区域、转移、腹水、双侧性)和绝经状态。对于卵巢肿块的分类,RMI的敏感性低于ROMA或OVA1,但特异性更高。在RMI中加入HE4似乎是最准确的。通过超声检查和彩色多普勒对卵巢囊肿进行主观评估优于ROMA和RMI算法,且不受激素状态影响。
