【摘要】 目的:回顾性评价应用血清CA125、超声分数及恶性肿瘤风险指数(RM I)对绝经后妇女附件肿物的良、恶性进行预测,对绝经后妇女附件肿物进行术前评价。方法:2001年1月~2005年12月,我院妇科病房共收治绝经后妇女附件肿物患者178例,其中140例为良性病变患者,38例为恶性肿瘤患者,分别以其术前血清CA125水平、超声分数及RM I对附件肿物的良、恶性进行预测,比较其敏感性、特异性及阳性预测值。结果:RM I较其它指标对绝经后附件良、恶性病变的预测更为准确。以RM I 200为界值,其敏感性为78.9%,特异性为90.0%,阳性预测值为68.2%。结论:RM I较其它指标对绝经后附件肿物良、恶性的预测更为准确且更易被接受,具有较大的临床应用价值。更多还原

【Abstract】 Objective:To evaluate the use of risk of Malignancy Index(RMI),based on a serum CA125 level,ultrasound findings in primary evaluation of postmenopausal women with adnexal masses.Methods:178cases of postmenopausal women with adnexal masses,admitted between January 2001 and December 2005,were studied.The sensitivity,specificity and positive predictive value of serum CA125 level,ultrasound findings combined into the RMI to distinguish malignant from benign pelvic masses.Results:RMI was more accurate than any individual criterion in diagnosing cancer.A cut-off level of 200 was chosen as the threshold,the RMI derived from this data set gave a sensitivity of 78.9%,specificity of 90.9%,and positive predictive value of 68.2%.Conclusion:RMI is an accurate,easily applicable method in the preoperative evaluation of postmenopausal women with adnexal masses.更多还原
