Application of ultrasonic tomography imaging in staging cervical cancers

Abstract

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.
