Objectives

Narrative objectives1

Squamous-cell carcinoma of the esophagus is known to be often associated with metachronous cancer in other organs. This is an important issue related to outcomes in patients who undergo endoscopic resection expected to cure esophageal cancer. The JEC-1 study, a previous exploratory study, found that patients with multiple LVL (Grade C of the JEC-1 study) had a high incidence of metachronous cancer in other organs. We planned a prospective cohort study to verify whether patients with Grade C multiple LVL have an increased incidence of metachronous cancer in other organs.

Basic objectives2

Others

Basic objectives -Others

We planned a prospective cohort study to verify whether patients with Grade C multiple LVL have an increased incidence of metachronous cancer in other organs. The analyses will be conducted after completing follow-up observations for 2, 5, and 10 years after enrollment of the last patient.

Assessment

Primary outcomes

The cumulative incidence of metachronous cancers in other organs according to the grade of LVL

Key secondary outcomes

Secondary Endpoints
1) The total numbers of metachronous cancers arising in other organs per person-year according to the grade of LVL
2) The cumulative incidences of head and neck cancer and of gastric cancer according to the grade of LVL
3) The total numbers of head and neck cancers and of gastric cancers per person-year according to the grade of LVL
4) The cumulative incidences of metachronous cancers in other organs in patients who successfully quit drinking alcohol and those who did not
5) The cumulative incidences of metachronous cancers in other organs in patients who successfully quit smoking and those who did not
6) The cumulative incidences of metachronous cancer in other organs in patients who received initial treatment for esophageal cancer and patients with a history of previous treatment
7) The total numbers of metachronous cancers in other organs per person-year in patients who received initial treatment for esophageal cancer and patients with a history of previous treatment

Other Analyses
1) Investigatory analysis of risk factors other than the grade of LVL for the development of metachronous cancer in other organs
2) Analysis of outcomes in enrolled patients (as compared with outcomes in the previous JEC-1 study)

Key inclusion criteria

1) Patients undergoing EMR or ESD for esophageal cancer (initially treated cases or previously treated cases)
2) Complete endoscopic resection is judged to be feasible.
3) A histopathological diagnosis of esophageal squamous cell carcinoma on examination of resected specimens
4) Vertical margins confirmed to be negative on examination of resected specimens
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 or ESD.
6) The attending physician judges that 10 or more years of follow-up observations are possible.
7) Written informed consent is obtained directly from the patient.

Key exclusion criteria

1) Registration in the JEC-1 study
2) A history of chemotherapy (including molecular targeted therapies)
3) A history of radiotherapy or surgical resection for head and neck cancer or esophageal cancer
4) Active double cancers in other organs (However, intramucosal cancers of other organs are not regarded to be active cancers in other organs.)
5) An allergy to iodine
6) Patients considered by their attending physicians to be unsuitable for enrollment in this study
