The role of endoscopic resection in long-term results of chemoradiotherapy for T1bN0M0 thoracic esophageal squamous cell carcinoma
Not Applicable
- Conditions
- T1bN0M0 thoracic esophageal squamous cell carcinoma
- Registration Number
- JPRN-UMIN000043568
- Lead Sponsor
- Keiyukai Sapporo Hospital
- Brief Summary
ER and tumor length were independent predictive factors for LRFS. Our study suggested that performance of ER prior to CRT improved the local control in patients with c/p T1bN0M0 ESCC. In addition, most of the patients who experienced local recurrence were treated with salvage ER, which contributed to preserving the organs.
