| neoadjuvant immunotherapy | Drug | 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. |
|
| Surgery | Procedure | 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. |
|
| adjuvant immunotherapy | Drug | 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. |
