Brief summary
This study aims to examine the efficacy of the combination of neoadjuvant chemoradiotherapy and perioperative PD-1 inhibitor in patients with locally advanced esophageal squamous cell cancer and explore the predictive biomarkers for this regimen.
Interventions
Neoadjuvant chemoradiotherapy: 1. Radiation dose: 1.8Gy/Fx, DT41.4Gy/23Fx. 2. Concurrent chemotherapy: Albumin-bound paclitaxel 60mg/m² + Cisplatin 25mg/m² on D1, D8, D15, D22, D29.
Begins on the second day after the completion of concurrent chemoradiotherapy, and no later than one week. Toripalimab 240mg Q3W, for a total of two cycles.
Preoperative assessment is conducted 3 weeks after the last neoadjuvant immunotherapy, and surgery is performed within 4-6 weeks. All patients undergo minimally invasive radical esophagectomy, either McKeown or Ivor-Lewis, with extended two-field or three-field lymph node dissection.
Whether to undergo postoperative adjuvant immunotherapy is determined based on the pathological response. Patients with pCR are only observed without receiving adjuvant treatment, while those not reaching pCR receive one year of adjuvant Toripalimab.
