Endoscopic Ultrasound after Preoperative Chemoradiation Can Help Identify Patients Who Benefit Maximally after Surgical Esophageal Resection

Abstract

Following preoperative chemoXRT and surgery, patients with residual tumor in the regional lymph nodes have lower actuarial survival at 1, 2, and 3 yr after surgery, compared to patients with path CR or with residual tumor only in the esophagus. EUS and EUS-guided FNA can be helpful in identifying residual tumor in the lymph nodes after preoperative chemoXRT to select patients who benefit maximally from surgery.
