摘要
目的:探讨不同年龄阶段卵巢恶性肿瘤的超声声像图特征及其与病理类型的相关性。方法:收集在中山大学附属第一医院行手术治疗的406例卵巢恶性肿瘤患者资料,分析不同年龄阶段肿瘤病理类型构成、超声声像学特征及两者相关性。结果:经病理确诊病灶508个,超声诊断病灶492个。青少年组以生殖细胞肿瘤为主;生育年龄组和绝经组以上皮性肿瘤为主。不同年龄阶段的病灶侧别和肿块内部回声特征均存在差异(P=0.016,P=0.001)。青少年组肿瘤病灶最大(P<0.001,P<0.001);绝经组肿块内低阻力指数(resistance index,RI)<0.5血流所占比例较生育年龄组高(P=0.003);腹腔积液阳性率在3组间差异无统计学意义(P=0.626)。术前超声诊断恶性肿瘤的真阳性率为83.00%;真阳性率在绝经组高于生育年龄组(P=0.006),在不同病理类型之间无差异(P=0.814)。结论:不同年龄阶段发生的卵巢恶性肿瘤,其病理类型及声像学特征存在差异。各病理类型超声诊断的真阳性率均较高,绝经组的诊断真阳性率最高。
Objective: To explore the correlation between ultrasonic characteristics and pathological types of malignant ovarian tumor at different ages. Methods: The ultrasonic features and pathological types were retrospectively analyzed in 406 patients with malignant ovarian tumor confirmed by operation and pathology. The correlation between them at different ages was analyzed. Results: A total of 508 lesions were confirmed by pathology, and 492 lesions were diagnosed by pre-operative ultrasound examination. The adolescent group was mainly composed of germ cell tumors, while epithelial ovarian tumor was the main type in the reproductive group and postmenopausal group. The differences in lesion location and ultrasonic features were statistically significant(P=0.016, P=0.001). The average lesion diameter in the adolescent group was larger compared with the other two groups(P<0.001, P<0.001). The proportion of resistance index(RI) <0.5 in the postmenopausal group was higher than that in the reproductive group(P=0.003). However, the positive rates of ascites were not statistically different among three groups(P=0.626). The positive rate of preoperative ultrasound diagnosis of malignant tumors was 83.00%, but it was not significantly different among various pathological types(P=0.814). The positive rate of ultrasound diagnosis in the postmenopausal group was significantly higher than that in the reproductive group(P=0.006). Conclusion: The pathological types and ultrasonographic characteristics are different at different ages. The positive rate of preoperative ultrasound diagnosis is high in different pathological types, It is higher in the postmenopausal group, especially for epithelial ovarian tumor.
