Assessing tumor response to predict post-surgery treatment in esophageal cancer

Tumor Regression Grade As Predictor of Adjuvant Therapy Benefits in Patients with Esophageal Squamous Cell Carcinoma After Neoadjuvant Therapy

Observational Fujian Medical University Union Hospital · NCT06710665

This study is testing if the way tumors shrink after treatment can help doctors decide the best follow-up care for patients with esophageal cancer after surgery.

What this trial studies

This observational study investigates the role of tumor regression grade (TRG) in predicting the effectiveness of adjuvant therapy for patients with esophageal squamous cell carcinoma (ESCC) who have undergone neoadjuvant therapy followed by surgery. Patients will be categorized based on their TRG scores into good responders and poor responders, and their overall survival will be monitored. The study aims to clarify the relationship between TRG and the necessity of adjuvant therapy, utilizing Cox proportional hazards regression models to analyze survival outcomes.

Who should consider this trial

Good fit: Ideal candidates are patients with locally advanced esophageal squamous cell carcinoma who have undergone R0 resection after neoadjuvant therapy.

Not a fit: Patients with incomplete clinical data or those diagnosed with multiple primary malignancies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help tailor postoperative treatment plans for ESCC patients, potentially improving survival rates.

How similar studies have performed: While the role of TRG in predicting outcomes has been explored in other cancers, its specific application in guiding adjuvant therapy for ESCC remains largely untested.
