Adjuvant Radiotherapy for Esophageal Squamous Cell Carcinoma in the Era of Immunotherapy
The Role of Adjuvant Radiotherapy in the Treatment for Resectable Locally Advanced Esophageal Squamous Cell Carcinoma After Neoadjuvant Chemotherapy Combined With Immunotherapy: A Multi-center, Phase II Randomized Clinical Study
This study is a multicenter, prospective, randomized phase II trial aimed at exploring the value of adjuvant radiotherapy in patients at high risk of recurrence after neoadjuvant chemoradiotherapy for esophageal cancer. The study primarily includes patients with esophageal cancer who underwent neoadjuvant chemoradiotherapy and surgery and did not achieve complete pathological response (non-pCR) postoperatively and were defined as preoperative clinical stage at T3-4N+M0.
Eligible patients will be randomized in a 1:1 ratio into two groups: the observation group and the adjuvant radiotherapy group. The control group consists of patients who receive surgery after neoadjuvant chemotherapy combined with immunotherapy for esophageal cancer, followed by maintenance therapy with PD1/PDL1 inhibitors for up to 1 year or until tumor progression. The adjuvant radiotherapy group receives additional adjuvant radiotherapy on top of the control group's treatment. The specific treatment process involves receiving 2 cycles of neoadjuvant chemotherapy combined with immunotherapy (PD1/PDL1 inhibitors) before potentially curative esophageal cancer surgery. The chemotherapy regimen includes paclitaxel in combination with platinum agents, with a preference for albumin-bound paclitaxel (280mg/m2 on Day 1, or 100mg on Days 1, 8, and 15) in combination with carboplatin (AUC=5). Following surgery, patients start adjuvant radiotherapy 4-6 weeks after the operation, with a radiation dose of 45Gy/25F/5W, completed no later than 8 weeks post-surgery. Two weeks after completing radiotherapy, patients continue with immunotherapy maintenance therapy for up to 1 year or until tumor progression. Subsequently, follow-up visits are scheduled every 3-4 months for the first 3 years, every 6 months for the next 2 years, and annually thereafter. The primary endpoint is 2-year disease-free survival (DFS), and secondary endpoints include overall survival (OS), local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), recurrence patterns, and safety assessment. Additionally, the study will explore biomarkers predicting treatment efficacy and adverse reactions in subjects, including PD-L1 expression, ctDNA clearance status, infiltrating immune cell types and quantities, cytokine expression, and other tumor biomarkers. This exploration aims to guide stratified precision treatment for patients.

Calculated creatinine clearance rate (CrCl) ≥50 mL/min. * CrCl will be calculated using the Cockcroft-Gault formula: CrCL (mL/min) = {(140 - age) × weight (kg) × F} / (SCr (mg/dL) × 72) where F = 1 for males and F = 0.85 for females; SCr = serum creatinine. ii.

Cardiac function: Left ventricular ejection fraction (LVEF) ≥ 50%.
- Female subjects of childbearing potential must have a negative urine or serum pregnancy test within 3 days before the first dose (if urine pregnancy test results cannot be confirmed as negative, a serum pregnancy test must be performed, and serum pregnancy test results will be used) and agree to use highly effective contraception continuously for 120 days after the last dose of study drug; the decision to stop contraception after this time point should be discussed with the investigator.
- Male subjects who are not surgically sterile and who are sexually active with female partners of childbearing potential must use effective contraception continuously from the screening period through 120 days after the last dose; the decision to stop contraception after this time point should be discussed with the investigator.

Intervention / Treatment |
---|---|
Experimental: Adjuvant radiotherapy
Following surgery, patients start adjuvant radiotherapy 4-6 weeks after the operation, with a radiation dose of 45Gy/25F/5W, completed no later than 8 weeks post-surgery.
Two weeks after completing radiotherapy, patients continue with immunotherapy maintenance therapy for up to 1 year (17 cycles Q3W) or until tumor progression.
|
The start time for radiotherapy is 4-6 weeks after surgery, typically not exceeding 8 weeks. Intensity-modulated radiation therapy (IMRT) will be used, with a total dose of 45Gy administered in 25 fractions, five times per week. The recommended target delineation for radiotherapy is based on the Chinese guidelines for radiation therapy of esophageal cancer, which mainly covers the high-risk lymph node area. |
Active Comparator: Observation
Patients receive surgery after neoadjuvant chemotherapy combined with immunotherapy for esophageal cancer, followed by active survillance and maintenance therapy with PD1/PDL1 inhibitors for up to 1 year (17 cycles Q3W) or until tumor progression.
