Parametrial invasion of uterine cervical cancer assessed by transrectal ultrasonography: preliminary report.
Transrectal ultrasonographic examinations were performed on 30 patients with uterine cervical cancer to assess parametrial invasion. The findings were compared with data obtained by manual rectal examination. Forty-six parametria in 23 patients were histologically examined following surgery. Sensitivity, specificity, positive predictive value, negative predictive value, and predictive accuracy of transrectal ultrasonography and rectal examination were 1.0 and 0.25 (P less than 0.05), 0.9 and 0.93, 0.5 and 0.25, 1.0 and 0.93, and 0.91 and 0.87, respectively. Therefore, transrectal ultrasonography may prove to be a useful diagnostic tool to determine the preoperative staging of uterine cervical cancer.
