Abstract:
Objective:To explore the difference of diagnostic accuracy of direct method and co-agent filling method in tumor invasion depth(T-staging) of rectal cancer by 360° transrectal ultrasonography(TRUS).Methods:67 patients with rectal cancer underwent TRUS before surgery to predict T-staging.The results were compared with the postoperative pathological results.Their consistency was evaluated by Kappa test.Results:The total accuracy rate of direct method and co-agent filling method of TRUS in T-staging of rectal cancer were 91.0% and 92.5%.The ultrasound result of two kinds of methods was highly consistent with the pathological result,but the latter(Kappa=0.846,P=0.000) was obviously higher than the former(Kappa=0.685,P=0.000).The diagnostic accuracy of T1 and T2 stage of rectal cancer evaluated by two kinds of methods were 89.2%,95.6% and 90.4%,93.7%.The diagnostic accuracy of T1 and T2 stage of rectal cancer of co-agent filling method was obviously higher than direct method.Conclusion:The diagnostic accuracy of tumor invasion depth of rectal cancer by co-agent filling method TRUS is higher than direct method,meanwhile,there are higher application value for T1 and T2 stage.
