Which Pre-Surgery combo extends life in esophageal cancer? a virtual trial seeks answers
NCT ID NCT07778056
First seen Aug 21, 2026 · Last updated Aug 21, 2026
Summary
This study compares two standard pre-surgery treatments for a common type of esophageal cancer: chemoradiotherapy (radiation plus chemo) versus immunochemotherapy (immunotherapy plus chemo). Using data from 400 patients' medical records, researchers will analyze which approach is linked to longer overall survival and better outcomes like tumor shrinkage. The goal is to provide real-world evidence to help guide treatment decisions for patients with resectable, locally advanced esophageal squamous cell carcinoma.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Neoadjuvant chemoradiotherapy (radiation plus platinum-based chemotherapy) versus neoadjuvant immunochemotherapy (PD-1 inhibitor plus platinum-based chemotherapy)
- What this could lead to
- If this comparison shows one approach is better, it could guide doctors in choosing the most effective pre-surgery treatment for esophageal cancer, potentially improving survival rates.
- What could go wrong
- This is an observational study using existing medical records, not a controlled experiment, so results may be influenced by unmeasured factors. The findings may not apply to all patients.

Who is studied
The study population consists of patients with locally advanced esophageal squamous cell carcinoma (ESCC) diagnosed at Henan Cancer Hospital between January 2013 and December 2025. Eligible patients are those who meet the inclusion criteria and initiated either neoadjuvant chemoradiotherapy (nCRT) or neoadjuvant immunochemotherapy (nICT) within 180 days after Time Zero. Patients are identified from electronic health records (EHR) including medical records, pathology reports, imaging reports, and prescription systems.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age ≥ 18 years at the time of diagnosis. 2. Histologically confirmed esophageal squamous cell carcinoma (ESCC). 3. Clinical stage cT3-4a N0-2 M0 or cT2N+ M0 (AJCC 8th edition), with no distant metastasis (M1), based on clinical staging records available at Time Zero. 4. ECOG performance status 0-1 (or proxy: total hospitalization days ≤14 days in the past year if ECOG PS is missing). 5. No prior antitumor therapy for esophageal cancer (surgery, radiotherapy, chemotherapy, targeted therapy, or immunotherapy). 6. Curative surgical intent documented at Time Zero. Exclusion Criteria: 1. Distant metastasis (M1) or clinically determined unresectable disease. 2. Active concurrent malignancy within 5 years prior to diagnosis (excluding basal cell carcinoma of the skin or carcinoma in situ). 3. Severe comorbidities significantly limiting life expectancy or precluding neoadjuvant therapy (proxy: total hospitalization days \>30 days in the past year). 4. Pregnancy or lactation. 5. Known contraindications or hypersensitivity to the study drugs.
