Objectives
Endoscopic resection (ER) is indicated for a wide range of superficial esophageal squamous cell carcinomas (ESCCs). We examined the long‐term outcomes in patients with pathological (p) invasion of ESCC into the T1a‐muscularis mucosae (MM) and T1b‐submucosa (SM) after ER, for which data on prognosis are limited.
Methods
Of the 1217 patients with superficial ESCC who underwent ER, 225 patients with a pathological diagnosis of ESCC invasion into the MM, minute submucosal invasion ≤200 µm (SM1), or massive submucosal invasion (SM2) were included. In patients with lymphovascular invasion, droplet infiltration, or SM2 invasion, additional treatments, including chemoradiation (CRT) or esophagectomy with two‐ to three‐field lymph node dissection, were recommended. The median observation period was 66 months (interquartile range 48–91 months).
