Official title
An Organ Preservation Strategies After Chemoradiotherapy Combined With Immunotherapy for Esophageal Cancer vs Cross Therapy.
Overview
Patients with locally advanced esophageal squamous cell carcinoma will randomly assigned to receive neoadjuvant chemo-radiotherapy combined with immunotherapy post organ preservation strategy (experimental group) or neoadjuvant chemo-radiotherapy followed by surgery (control group). The 3-year overall survival rate is the primary outcome.
Detailed description
The investigators will conduct the open, multicenter, prospective, randomized controlled clinical study(PALACE3). Patients with locally advanced esophageal squamous cell carcinoma will randomly assigned to either receive neoadjuvant synchronous radiotherapy and chemotherapy combined with immunotherapy followed by organ preservation strategy (experimental group, Arm1) or neoadjuvant concurrent radiotherapy and chemotherapy followed by radical surgery (control group,Arm 2). Collect relevant data on preoperative treatment, re examination after neoadjuvant therapy, perioperative and long-term follow-up of patients, and evaluate the clinical treatment effects (cCR rate), surgical pathological results (pCR rate, R0 resection rate, tumor regression grade, lymph node positivity rate), neoadjuvant therapy and perioperative complications, long-term oncological effects (total survival, disease-free survival), and quality of life of the two treatment plans through statistical analysis.
Interventions
- Combination product Experimental: Arm 1 Organ preservation
Arm 1 patients will undergo clinical response evaluations (CREs) after neoadjuvant therapy(A+B+C）, If cancer is detected, surgery will be performed. Patients with clinical complete response （cCR） are eligible for active surveillance where regular CREs are performed to detect regrowth of cancer.Postoperative adjuvant therapy will follow the NCCN guideline. A: Camrelizumab 200mg IV on days 1 and 22 B: Carboplatin (AUC=2) IV and Paclitaxel-albumin (50mg/m²) IV on day 1,8,15,22,29. C: Radiotherapy - Combination product Active Comparator: Arm 2 Surgery
Arm 2 patients will undergo surgery after neoadjuvant therapy(B+C）.Postoperative adjuvant therapy will follow the NCCN guideline. B: Carboplatin (AUC=2) IV and Paclitaxel-albumin (50mg/m²) IV on day 1,8,15,22,29. C: Radiotherapy will start on day 1 of chemotherapy. A total of 41.4 Gy, 23 fractions of 1.8 Gy, 5 fractions a week.
Primary outcome measures
- 3-year overall survival rate [Time frame: From date of randomization until the date of death from any cause，up to 5 years]
