Abstract
Summary
Objective: Calculating the Se, Sp of MRI in determining the extramural invasiveness of rectal cancer. Subject and method: 50 patients with definitive diagnosis as rectal cancer underwent surgery at 103 Military Hospital and Viet Duc Hospital from Mar. 2018 to Feb. 2019. Comparison T staging by MRI and T staging postoperatively with Kappa and matrix table 2 × 2. Comparison tumor size measuring on MRI and those postoperatively with ICC. Result: Good correlation between the tumor size measuring on MRI and those postoperatively, ICC = 0.785. Good correlation between T staging by MRI and those postoperatively, K = 0.731. Overall, accuracy of MRI in T staging was 84%. Se, Sp of MRI for T1, 2 were 58.3% and 97.4%, respectively. Se, Sp of MRI for T3 were 96% and 72%, respectively. Se, Sp of MRI for T4 were 84.6% and 100%, respectively. Conclusion: MRI is helpful for determening T staging of rectal cancer.
Keywords: MRI, rectal cancer, stage, accuracy, invasiveness.
