Neoadjuvant SBRT Followed by Sintilimab Plus Chemotherapy for N3-Positive NSCLC
China28 participantsStarted 2025-12-31
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:

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. 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.
