Baseline T Classification Predicts Early Tumor Regrowth After Nonoperative Management in Distal Rectal Cancer After Extended Neoadjuvant Chemoradiation and Initial Complete Clinical Response

BACKGROUND: Selected patients with rectal cancer and complete clinical response after neoadjuvant chemoradiation have been managed nonoperatively with acceptable outcomes. However, ≈20% of these patients will develop early tumor regrowth. Identification of these patients could select candidates for more intensive follow-up. OBJECTIVE: The purpose of this study was to investigate the influence of baseline radiological T classification on...
