Transvaginal color doppler sonography combined with colposcopy for diagnosis of early stage cervical cancer and precancerous lesions.

This study aims to assess the value of transvaginal color Doppler sonography (TVCD) combined with colposcopy for diagnosis of early stage cervical cancer and precancerous lesions. From January 2015 to September 2016, one hundred patients, diagnosed as having early stage cervical cancer and precancerous lesions by histopathological study, were selected as the observation subjects. All patients were examined by TVCD and colposcopy, and the results were compared with histopathological findings. The diagnostic accuracy, sensitivity and specificity of TVCD alone, colposcopy alone, and TVCD combined with colposcopy in early stage of cervical cancer and precancerous lesion were compared. The sensitivity, specificity and accuracy of TVCD combined with colposcopy were significantly higher than that of TVCD (P < 0.05), and the sensitivity was significantly higher than that of colposcopy (P < 0.05). The high sensitivity, specificity and accuracy of TVCD combined with colposcopy on the diagnosis of invasive cervical carcinoma (ICC) and cervical intraepithelial neoplasia (CIN) can provide a scientific basis for its use in clinical diagnosis.
