Response evaluation with endoscopic ultrasound and computed tomography in esophageal squamous cell carcinoma treated by definitive chemoradiotherapy

Background and Aim We assessed the feasibility of combined endoscopic ultrasound and computed tomography on response evaluation in patients with esophageal squamous cell carcinoma treated by definitive chemoradiotherapy, and the impact of response on prognosis. Methods Sixty patients treated by definitive chemoradiotherapy were followed by miniprobe endoscopic ultrasound and computed tomography. The post‐treatment esophageal wall thickness was...
