本研究旨在评价盆腔超声(US)发现的不明确囊肿的发生率,明确其恶性率,识别囊肿与恶性肿瘤的特点,并将结果发表在Radiology上。

本研究对US发现的性质不明确囊肿并进行随访(手术病理检查、影像学和或临床检查)进行研究。性质不明确囊肿被分为1类(典型良性表现的囊肿>5cm)或2类(囊肿含有非血管的实性成分)。计算肿瘤的发生率以及恶性肿瘤发生率。利用

χ 2 检验或Fisher精确检验(分类变量)和T检验(连续变量)评价患者和囊肿特征与肿瘤和恶性肿瘤相关的指标,利用后退法Logistic回归模型来比较两种结果:(a)肿瘤(恶性或良性)(b)恶性肿瘤。

结果为,共有1637例US检出附件囊肿的女性患者,其中有391例患者(平均年龄= 41.8岁± 13.5;范围= 17-91 岁)的US检查囊肿性质不明确。性质不明确囊肿的发生率为23.9% (391/1637; 95%CI: 0.22, 0.26)。对280例患者(平均年龄= 42.9岁± 14.1;范围= 17-88岁)的303处病变进行了充分地随访。卵巢肿瘤(良性或恶性)的发生率为24.8% (75 /303; 95% CI: 0.20, 0.30),恶性肿瘤的发生率为3.6% (11 of 303 cysts; 95% CI: 0.02, 0.06)。卵巢肿瘤在两分类间的比例为(17.5% [25/143; 95% CI: 0.12, 0.25] vs 31.3% [50/160; 95% CI: 0.24, 0.39], P = .001)。恶性肿瘤的发生率在两分类间的比例为(0% [0/143] vs 6.9% [11/160; 95% CI: 0.03, 0.12]; P < .001)。囊肿内有非血管实性成分是恶性肿瘤的特征性表现(OR= 2.83; P ≤ .0001; 95% CI: 1.69, 4.70)。

本研究表明,对于性质不明确囊肿,囊肿内有非血管实性成分是恶性肿瘤的特征性表现。分类2囊肿恶性的风险要高于分类1。
