Preoperative staging of rectal cancer by pelvic mr imaging: results after 3 years
Main Article Content
Abstract
SUMMARY
Introduction: Colorectal cancer is the most common cancer of the gastrointestinal tract. Rectal cancer is the second most common cancer in Vietnam. Preoperative staging of rectal cancer has an important role to select the most appropriate treatment.
Purpose: To access the role of pelvic MR imaging in preoperative staging of rectal carcinoma.
Materials and methods: Preoperative pelvic MRI of 110 patients with rectal cancer was performed in University Medical Center at HCMC for 3 years. Staging was made by evaluating images obtained and compared with postoperative histopathologic staging.
Results: The accuracy of pelvic MR imaging for defining the T stage of rectal cancer was 89%. The accuracy rate to detecting lymph node metastases was 92.5%.
Conclusions: Pelvic MR imaging is a promising technique for accurate preoperative staging of rectal cancer.
