Plain-language summary
This is a Phase II clinical trial evaluating the efficacy and safety of a new treatment approach for patients with locally advanced non-small cell lung cancer (NSCLC) that has spread to lymph nodes on the opposite side of the chest (known as N3 lymph node involvement).
The study will enroll 28 patients aged 18 to 75 years with previously untreated, potentially resectable NSCLC classified as stage IIIB-IIIC. Participants will receive a combination of stereotactic body radiation therapy (SBRT) to the primary lung tumor, followed by two cycles of sintilimab (an immunotherapy drug) plus platinum-based chemotherapy before surgery.
The main goals of the study are to see whether this treatment can shrink or eliminate cancer in the contralateral mediastinal lymph node (lymph node downstaging) and allow more patients to undergo curative surgery. Secondary goals include assessing pathological response rates, surgical outcomes, survival, and safety.
Patients will be closely monitored during and after treatment, with follow-up visits planned for up to 5 years after surgery.

Inclusion criteria
✓. Voluntary Participation: The patient volunteers to participate and signs a written informed consent form.
✓. Pathology and Staging: Cytologically or histologically confirmed, previously untreated non-small cell lung cancer (NSCLC) with contralateral mediastinal lymph node involvement (N3), classified as stage IIIB or IIIC according to the 9th edition of the International Association for the Study of Lung Cancer (IASLC) staging manual. Baseline staging must be performed with either PET/CT or a combination of contrast-enhanced CT of chest/abdomen + bone scan + brain MRI.
✓. Surgical Feasibility: The lung lesion is considered \*\*potentially resectable as evaluated by a multidisciplinary team that includes a thoracic surgeon.
✓. Performance Status: Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1.
✓. Adequate Organ Function:
Exclusion criteria
✕. Autoimmune Disease: Active or suspected autoimmune disease. Exception: Patients with vitiligo, type I diabetes mellitus, or hypothyroidism requiring only hormone replacement therapy (e.g., Hashimoto's thyroiditis) with no signs of active disease may be enrolled.
. Immunosuppressive Therapy: Requires systemic corticosteroid therapy (\>10 mg daily prednisone or equivalent) or other immunosuppressive medications within 14 days prior to enrollment.
✕. Prior Chest Radiotherapy: History of prior radiotherapy to the chest.
✕. Active Bleeding: Presence of clinically significant active bleeding prior to treatment.
✕. Severe Organ Dysfunction: Severe cardiac, pulmonary, hepatic, or renal dysfunction, hematopoietic system disease, or cachexia, as judged by the investigator to be intolerable to chemo-radiotherapy.
✕. Poorly Controlled Diabetes: History of diabetes mellitus for \>10 years with unsatisfactory glycemic control.
✕. Interstitial Lung Disease: History of interstitial lung disease or non-infectious pneumonitis.
✕. Driver Gene Mutations: NSCLC with known activating EGFR mutations or ALK fusion gene positivity.
