Study Arms (2)
Adjuvant therapy arm
EXPERIMENTALFor participants assigned the adjuvant therapy arm, those who underwent neoadjuvant chemoradiotherapy followed by surgery will receive adjuvant chemoimmunotherapy. For patients who underwent neoadjuvant chemotherapy followed by surgery, or upfront surgery without prior neoadjuvant therapy, the choice between Option 1 (adjuvant chemoradioimmunotherapy) and Option 2 (adjuvant chemoimmunotherapy) will be made at the investigator's discretion. Adjuvant chemoradioimmunotherapy.
Surveillance arm
NO INTERVENTIONSurveillance arm will be followed up without any adjuvant therapy, undergoing CT scans every 12 weeks during the first 2 years after randomization, and thereafter every 24 weeks until 5 years after randomization
Interventions
1. Option 1: adjuvant chemoradioimmunotherapy in the following sequence: * Cycle 1: Tislelizumab 200 mg iv D1, Paclitaxel 175 mg/m2 iv D1, and Carboplatin AUC 5 mg/mL/min iv D1, in a 3-week cycle for one cycle * Cycle 2: Concurrent radiotherapy (25 fractions of 1.8 Gy each, with 5 fractions per week) with Tislelizumab 200 mg iv D1, D22, Paclitaxel 50 mg/m2 iv D1, 8, 15, 22, 29, and Carboplatin AUC 2 mg/mL/min D1, 8, 15, 22, 29 * Cycle 3: Tislelizumab 200 mg iv D1, Paclitaxel 175 mg/m2 iv D1, and Carboplatin AUC 5 mg/mL/min iv D1, in a 3-week cycle for 1 cycle * Cycles 4-9: Tislelizumab 400 mg iv D1, in a 6-week cycle for six cycles 2. Option 2: adjuvant chemoimmunotherapy in the following sequence: * Cycles 1-4: Tislelizumab 200 mg iv D1, Paclitaxel 175 mg/m2 iv D1, and Carboplatin AUC 5 mg/mL/min iv D1, in a 3-week cycle for four cycles * Cycles 5-10: Tislelizumab 400 mg iv D1, in a 6-week cycle for six cycles
Eligibility Criteria
You may qualify if:
- \. Be willing and able to provide written informed consent. 2. Be ≥19 years of age on the day of signing the informed consent form. 3. Have ECOG performance status of 0 or 1 (Appendix 1). 4. Have a histologically confirmed diagnosis of squamous cell carcinoma of the esophagus
- Patients with tumors of mixed histology (i.e., squamous and non-squamous) are eligible if the predominant histological component is squamous, except when small cell or neuroendocrine elements are present.
- \. Must have completed surgical resection for localized disease, either with prior neoadjuvant therapy (chemotherapy or chemoradiotherapy) or without prior neoadjuvant therapy (i.e., upfront surgery), in accordance with the 8th edition of the AJCC staging system (Appendix 2). Exceptionally, cases with supraclavicular lymph node metastasis as the only M1 lesion are also eligible if the lymph node has been surgically removed.
- \. Must have undergone curative surgery (R0 resection) with negative margins on the resected specimen.
- \. Complete resection must have been performed between 4-16 weeks before randomization.
- \. Must have a documented disease-free status based on a complete physical examination and imaging studies within 4 weeks before randomization. Imaging studies must include CT scans (or MRI) of the chest, abdomen, and pelvis.
- \. Must provide tumor tissue from pre-treatment biopsy (i.e., a biopsy obtained prior to neoadjuvant therapy in cases where neoadjuvant therapy is followed by surgery) or from surgical specimens and baseline blood samples for post-surgery ctDNA-MRD measurement and biomarker analyses.
- For patients who underwent upfront surgery, surgical tissue is preferred.
- For those who received neoadjuvant therapy followed by surgery, pre-treatment biopsy tissue is required. If pre-treatment biopsy tissue is unavailable or inadequate, submission of surgical specimens may be permitted following approval by the Study Sponsor.
- A FFPE tumor specimen in a paraffin block or 20 (at least 10, with a thickness of 10 µm) freshly cut unstained FFPE slides, along with one H\&E-stained slide, must be submitted with the associated pathology report. If an insufficient number of slides is available, the decision on patient enrollment can be made in consultation with the Study Sponsor.
- Peripheral blood of approximately 4 mL must be collected for germline DNA analysis.
- Peripheral blood of approximately 20 mL must be collected between 3 to 12 weeks after curative surgery for ctDNA testing.
- \. Must be confirmed to have MRD-positive status via postoperative baseline ctDNA testing.
- \. Must have adequate major organ functions as demonstrated by the following laboratory results obtained within 14 days before randomization (these criteria must also be met within 7 days before initiating study treatment in the adjuvant therapy arm):
- Adequate bone marrow function defined by:
- +9 more criteria
You may not qualify if:
- \. Documented recurrence of esophageal cancer before randomization following curative resection.
- \. Receipt of any treatment aimed at the resected esophageal cancer after curative surgery, including chemotherapy, targeted therapy, immunotherapy, radiotherapy, biologic therapy, investigational agent, or local therapies, except for procedures intended for palliative care (e.g., stent insertion, balloon dilatation, or feeding enterostomy).
- \. Prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, or anti-cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) inhibitor, or any other drug targeting T-cell co-stimulation or checkpoint pathways.
- \. Active autoimmune disease requiring systemic treatment within the 2 years prior to study entry (i.e., using disease-modifying agents, corticosteroids, or immunosuppressive drugs).
- Replacement therapy (e.g., thyroxine for autoimmune-related hypothyroidism, insulin for type 1 diabetes mellitus, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed.
- \. Condition requiring systemic treatment with corticosteroids (\>10 mg daily prednisone or equivalent) or any other form of immunosuppressive therapy within 14 days prior to study entry.
- Use of topical, ocular, intra-articular, intranasal, and inhaled corticosteroids is permitted if there is no active autoimmune disease.
- A short course of corticosteroids for prophylaxis (e.g., contrast dye allergy) or treatment of non-autoimmune conditions (e.g., delayed-type hypersensitivity reaction caused by contact allergens) is permitted.
- \. Receipt of a live vaccine within 28 days prior to study entry.
- COVID-19 vaccines are allowed except for any live vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g., FluMist®) are live attenuated vaccines and are not allowed.
- \. Active infection requiring systemic therapy within 14 days prior to study entry.
- \. History of severe hypersensitivity to paclitaxel, carboplatin, or any antibody products.
- \. Known history of, or any evidence of, interstitial lung disease, non-infectious pneumonitis, or pulmonary fibrosis diagnosed based on imaging or clinical findings.
- Subjects with radiation pneumonitis may be enrolled if radiation pneumonitis is stable (beyond the acute phase) and unlikely to recur.
- \. History of allogeneic stem cell or solid organ transplantation. 11. Malignancies other than esophageal cancer within the 3 years prior to study entry, except for malignancies with a negligible risk of metastasis or death (e.g., 5-year OS rate \>90%), such as adequately treated non-melanoma skin cancer, superficial bladder cancer, or carcinoma in situ (e.g., cervix, breast, or prostate).
