Predicting how well chemotherapy will work for esophageal cancer patients

Official title: Predicting Postoperative Chemotherapy Efficacy in Patients With Esophageal Squamous Cell Carcinoma by Biopsy Specimens.

Run by City of Hope Medical Center · NCT06490003 · Data updated 2026-11-12

This study is testing if DNA changes in biopsy samples can help doctors predict how well chemotherapy will work for patients with esophageal cancer, so those who might not benefit can avoid unnecessary treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are patients with histologically confirmed esophageal squamous cell carcinoma who are receiving initial chemotherapy.

Probably not a fit

Patients who cannot provide a preoperative biopsy sample or those with multiple cancers may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study focuses on patients with esophageal squamous cell carcinoma to develop a predictive model for chemotherapy efficacy based on DNA methylation patterns found in preoperative biopsy specimens. By identifying patients who are unlikely to respond to chemotherapy, the study aims to help them avoid unnecessary treatment and its associated side effects. This could allow for timely adjustments to their treatment plans, potentially improving overall outcomes. The study involves patients who have undergone chemotherapy and aims to analyze their responses over a two-month period.

Why it matters

Potential benefit: If successful, this study could help tailor chemotherapy treatments for esophageal cancer patients, improving their chances of receiving effective therapies.

How similar studies have gone: While there have been studies exploring biomarkers for chemotherapy response, this specific approach using DNA methylation in esophageal cancer is relatively novel.
