Conditions
Summary
The prognosis of patients with esophageal squamous cell carcinoma (ESCC) who develop post-operative early tumor recurrence is often relatively poor. Therefore, biomarker that can detect micro metastases before the start of treatment is required. Epigenomic alterations such as DNA methylation have attracted attention as promising biomarkers. The investigators aim to predict early recurrence based on whole genome DNA methylation analysis of esophageal cancer.

- Patients for whom tissue samples are available
- Patients who were followed-up completely, with information on observation periods of at least 2 years after surgery.
- Written informed consent following full study information is provided to the patient.
Exclusion Criteria2
- Patients lacking clinical information within 2 years of surgery.
- Patients with multiple cancers.
