计算机断层扫描与超声在卵巢囊性及囊实性肿瘤良恶性诊断中的应用比较

Comparison of application of computed tomography and ultrasound for benign and malignant differential diagnosis on ovarian cystic and cystic solid tumors

目的探究计算机断层扫描(CT)与超声(US)两种检查方法在卵巢囊性及囊实性肿瘤良恶性诊断中的应用价值。方法收集80例卵巢囊性或囊实性肿瘤患者的病历资料,术前1周进行CT及US检查,根据术后病理结果将其分为良性组(n=56)及恶性组(n=24),比较两种检查方法在卵巢囊性及囊实性肿瘤良恶性诊断中的应用价值。结果 CT诊断卵巢恶性肿瘤的灵敏度及特异度分别为95.83%(23/24)、92.86%(52/56),US诊断卵巢恶性肿瘤的灵敏度及特异度分别为79.17%(19/24)、83.93%(47/56),差异均无统计学意义(χ~2=3.048、2.176,P=0.081、0.341);CT诊断卵巢囊性恶性肿瘤的灵敏度及特异度分别为100%(1/1)、88.24%(15/17),US诊断卵巢囊性恶性肿瘤的灵敏度及特异度分别为100%(1/1)、82.35%(14/17),差异均无统计学意义(χ~2=0.000、0.235,P=1.000、0.628);CT诊断卵巢囊实性恶性肿瘤的灵敏度及特异度分别为95.65%(22/23)、94.87%(37/39),US诊断卵巢囊实性恶性肿瘤的灵敏度及特异度分别为78.26%(18/23)、84.62%(33/39),差异均无统计学意义(χ~2=3.067、2.229,P=0.080、0.135);CT诊断淋巴结转移、侵犯周围组织脏器,以及腹腔、肠系膜或大网膜种植的准确率均高于US,差异均有统计学意义(χ~2=5.169、4.752、4.752,P=0.023、0.029、0.029);CT与US诊断腹腔积液的准确率比较,差异无统计学意义(χ~2=0.356,P=0.551)。结论 CT与US检查在卵巢囊性及囊实性肿瘤良恶性诊断中均具有一定的临床应用价值,且CT检查对恶性肿瘤间接征象的诊断优势更加突出。

Objective To explore the application values of computed tomography(CT)and ultrasound(US)in the benign and malignant diagnosis on ovarian cystic and cystic solid tumors.Method The data of80patients with ovarian cystic or cystic solid tumors were collected.They were given the CT and US tests at1week before operation and divided into benign group(n=56)and malignant group(n=24)according to the postoperative pathology results.The application values of the two imaging examinations in the benign and malignant diagnosis on ovarian cystic and cystic solid tumors were compared.Result The sensitivity and specificity in the diagnosis of malignant ovarian tumor by CT were95.83%(23/24)and92.86%(52/56),which were not significantly different from those by US,as79.17%(19/24)and83.93%(47/56)(χ^2=3.048,2.176;P=0.081,0.341).The sensitivity and specificity of CT in the diagnosis of malignant ovarian cystic tumors were100%(1/1)and88.24%(15/17),which were not significantly different from those of US,as100%(1/1)and82.35%(14/17)(χ^2=0.000,0.235;P=1.000,0.628).The sensitivity and specificity of CT in the diagnosis of malignant ovarian cystic and solid tumors were95.65%(22/23)and94.87%(37/39),which were not significantly different from those of US,as78.26%(18/23)and84.62%(33/39)(χ^2=3.067,2.229;P=0.080,0.135).The accuracy rates in diagnosis of lymph node metastasis,invasion of adjacent organs,implantation of abdominal cavity,mesentery and greater omentum by CT were all significantly higher than those by US(χ^2=5.169,4.752,4.752;P=0.023,0.029,0.029).There was no significant difference in the accuracy rate of diagnosis of ascites between CT and US(χ^2=0.356,P=0.551).Conclusion Both CT and US examination have certain clinical application value in the benign and malignant diagnosis of ovarian cystic and cystic solid tumors.And the diagnostic advantages by CT examination for indirect signs of malignant tumors are more prominent.
