三维断层超声成像在宫颈癌术前分期中的应用

摘要

Objective To evaluate the clinical value of tomography ultrasonic imaging (TUI) in staging carcinomas of the cervix.Methods Eighty-seven patients with biopsy proven cervical cancer who underwent transvaginal TUI examination were enrolled.Clinical and ultrasonic staging were based on the FIGO staging system.Surgical-pathological or MR results was taken as golden standard.Ultrasonic staging were compared with clinical staging.Tumor sizes of 38 cases of cervical cancers measured by TUI were recorded and compared with the pathological results.Results The overall accuracy of preoperative TUI staging was higher than that of preoperative clinical staging (91.95 ％ vs 81.60 ％,P ＜0.01).Mean size of the 38 malignant tumors was 2.5 cm×2.1 cm×2.2 cm by TUI and 2.6 cm×2.1 cm×2.3 cm by pathological samples (P ＞ 0.05).Conclusions TUI technology may be useful in the noninvasive examination of preoperative staging of carcinoma cervix.%目的 评价三维断层超声成像(TUI)技术在宫颈癌术前分期中的应用价值.方法 对87例经组织活检确诊为富颈癌患者进行经阴道TUI检查,并参考FIGO(2009)分期标准对患者进行超声术前分期,以手术病理结果或盆腔磁共振(MR)检查结果为金标准,比较超声术前分期和临床术前分期的准确性.结果 使用TUI技术对宫颈癌术前分期的准确率较临床分期准确率高,差异有统计学意义(91.95％对81.60％,P＜0.05).其中,ⅡB期超声术前分期准确率为90％,临床术前分期准确率为30％,差异有统计学意义(P＜0.05).结论 与临床术前分期相比,TUI技术有助于提高宫颈癌术前分期准确率,是一项较有临床价值的检查方法.
