Is T classification still correlated with lymph node status after preoperative chemoradiotherapy for rectal cancer?

Abstract

Pathologic T classification is still the most reliable predictor of lymph node metastasis in rectal cancer patients who have undergone preoperative CRT. The risk of lymph node metastasis was found to be 3.4% in rectal cancer that had regressed to ypT0 or ypT1.
