Impact of Time to Endoscopic Resection on Outcomes for Stage I Esophageal Adenocarcinoma.

BACKGROUND: Endoscopic resection (ER) is the preferred treatment for superficial esophageal cancer; however, a safe time frame for performing ER has not been established. This study evaluated the period in which ER can be performed for patients with stage I esophageal adenocarcinoma without compromising outcomes. METHODS: The 2004-2015 National Cancer Database was used to identify patients with cT1 N0 M0 esophageal adenocarcinoma who underwent upfront ER. The primary outcome was overall survival, which was evaluated using Kaplan-Meier and multivariable Cox proportional hazards methods. The secondary outcome was rate of margin-positive resection, which was evaluated using a multivariable logistic regression. RESULTS: A total of 983 patients met study criteria. The median time from diagnosis to ER was 34 days (interquartile range, 5-70 days). Patients in the highest quartile of time to ER were more likely to be treated at a high-volume center and at a center different from that of diagnosis compared with those in the lowest quartile. Increasing time to ER was not independently associated with survival (adjusted hazard ratio per 10 days, 1.02; 95% confidence interval, 0.98-1.05; P = .32) or margin-positive resection (odds ratio per 10 days 1.01; 95% confidence interval, 0.96-1.06; P = .60). CONCLUSIONS: In this National Cancer Database analysis, increasing time to endoscopic resection, up to 180 days from diagnosis, was not associated with worsened survival or increased odds of margin-positive resection in patients with cT1 N0 M0 esophageal adenocarcinoma. Given these findings, patients may be afforded time to be seen in specialty centers without risk of tumor progression.
