Objectives
Narrative objectives1 Previous studies have reported that multiple Lugol-voiding lesions of the background esophageal mucosa are associated with a very high risk of multiple cancers in the esophagus, as well as the head and neck region. The ability to use Lugol-voiding pattern as a biomarker for the risk of second primary cancers in the esophagus and head and neck region after endoscopic mucosal resection (EMR) in patients with esophageal cancer would facilitate the early detection and treatment of metachronous multiple cancers, contribute to improved outcomes of EMR, and thereby approach a more ideal surveillance period after EMR.

Assessment
Primary outcomes The cumulative incidence of metachronous multiple cancers of the esophagus as assessed by the Lugol-voiding pattern.
Key secondary outcomes 1) The total annual number of cases of metachronous multiple cancer of the esophagus as assessed by the Lugol-voiding pattern.
2) The cumulative incidence of metachronous multiple cancers of the head and neck region as assessed by the Lugol-voiding pattern.

Key inclusion criteria (1) Newly diagnosed early squamous cell carcinoma of the esophagus.
(2) Complete endoscopic resection as assessed visually on Lugol chromoendoscopy immediately after EMR.
(3) A diagnosis of squamous cell carcinoma on histopathological examination of the resected specimen.
(4) Vertical margins of the resected specimen are confirmed to be tumor-negative.
(5) Tumor invasion is limited to the mucosa on histopathological examination of the resected specimen, and no additional treatment (surgical resection, radiotherapy, chemotherapy, etc.) is performed immediately after EMR.
(6) No active head or neck cancers.
(7) The investigator judges that patient can be observed for at least 2 years.
(8) Written informed consent is obtained from the patient.
Key exclusion criteria (1) A history of chemotherapy for any other cancers or a history of surgical treatment or radiotherapy for head and neck cancers.
(2) A history of iodine allergy.
(3) Patients whom the investigator considers unsuitable as subjects for this study.
