Abstract:
Objective To evaluate the accuracy of preoperative three-dimensional endoscopic ultra-sonography (3D-EUS) in tumor invasion depth (T-staging) of rectal cancer. Methods From May 2007 to November 2007, 21 patients with rectal cancer diagnosed by eolonoscopy and biopsy, underwent 3D-EUS, 2D-EUS and MRI before surgery to predict T-staging. The results were assessed according to post-surgical pathological findings. Results The accuracy of 3D-EUS in T-staging was 85.71%, which was significantly higher than that of MRI (57.14%, P<0.05), and similar with that of 2D-EUS (76.19%, P>0.05). Conclusion More accurate T-staging could be achieved by 3D-EUS, which could be combined with MRI to detect lymph node metastasis, and provide more information for therapy decision in rectal cancer.
