Compared with the overall non-pCR population, the subgroup with lymph node positivity has a significantly worse prognosis. The CheckMate 577 study confirmed that in patients with locally advanced resectable esophageal cancer or esophageal-gastric junction cancer, adjuvant treatment with nivolumab after nCRT significantly prolonged disease-free survival compared with placebo (median DFS: 22.4 months vs 11.0 months; HR=0.69, p\\<0.001).\n\nThe current research focus has expanded to the field of neoadjuvant chemoimmunotherapy, but the adjuvant treatment strategy after such therapy remains a blank slate. Given that esophageal squamous cell carcinoma (ESCC) is the predominant type of esophageal cancer in our country, it is of great clinical significance to explore adjuvant treatment strategies after neoadjuvant chemoimmunotherapy combined with radical resection.\n\nBased on the above background, we have designed a randomized controlled trial (RCT) to evaluate the efficacy of adjuvant immunotherapy versus observation alone in patients with ESCC after neoadjuvant chemoimmunotherapy, with the hope of providing evidence-based medical evidence for this population.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Aged ≥18 years.\n* Histologically confirmed esophageal squamous cell carcinoma.\n* Preoperative staging of cT1b-cT2N+M0 or cT3-cT4a, any N, M0 (UICC/AJCC TNM staging, 8th edition, 2017), and treated with neoadjuvant therapy using an immunotherapy combined with a taxane and platinum regimen, followed by radical surgical resection.\n* R0 resection.\n* Postoperative pathological staging of ≥ypT1 and/or ≥ypN1.\n* Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≤1.\n* Physical examination and imaging studies completed within 4 weeks prior to randomization confirming disease-free status, with imaging studies including CT scans of the chest and abdomen.\n* Normal function of major organs.\n* Women of childbearing potential and men with partners of childbearing potential must agree to use effective contraception during the treatment period and for 6 months before and after the treatment period.\n* Willingness of the subject to participate in the study and provision of informed consent.\n* Good compliance of the subject, with the ability to follow up on efficacy and adverse events/reactions as required by the study plan.\n\nExclusion Criteria:\n\n* Presence of blood-borne infectious disease human immunodeficiency virus (HIV).\n* Presence of psychiatric disorders.\n* History of any other malignancy within the past 5 years (except for completely cured cervical carcinoma in situ or basal cell or squamous cell carcinoma of the skin).\n* Treatment in the ICU due to severe complications after radical surgery for esophageal cancer.\n* Severe anastomotic stricture after surgery, requiring dilation treatment.\n* Known severe allergy to any component of the study drug.\n* Presence of other autoimmune diseases, or long-term systemic use of immunosuppressants or corticosteroids; the use of inhaled or topical corticosteroids or equivalent doses of adrenal corticosteroid replacement therapy is permitted.\n* Active hepatitis B (HBV-DNA ≥ 2000 IU/mL or 10⁴ copies/mL), hepatitis C (positive hepatitis C antibody, and HCV-RNA above the lower limit of detection of the assay).
