Radiation boosts immunotherapy in lung cancer? new trial aims to find out
NCT ID NCT07353476
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at people with stage III non-small cell lung cancer who had chemotherapy plus immunotherapy before surgery, and still had cancer in their lymph nodes after the tumor was removed. Half will get standard immunotherapy alone after surgery, and the other half will get immunotherapy plus radiation to the lymph nodes. The goal is to see if the combination helps keep the cancer from coming back longer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- radiation therapy and an anti-PD-1 immunotherapy drug
- What this could lead to
- If it works, this could point toward a more effective treatment plan for lung cancer patients who still have cancer in their lymph nodes after surgery and chemotherapy.
- What could go wrong
- This is a small, early-phase study with only 38 participants, so results may not apply to everyone. Adding radiation also raises risks of side effects like lung inflammation.

Inclusion Criteria: * Age 18-75 years, male or female. * Histologically confirmed NSCLC (adenocarcinoma, squamous cell carcinoma, or other NSCLC subtypes). * Clinical stage IIIA/IIIB at initial diagnosis, deemed suitable for neoadjuvant chemoimmunotherapy followed by surgery according to MDT. * Completed 2-4 cycles of platinum-based doublet chemotherapy plus PD-1 inhibitor as neoadjuvant therapy. * Underwent R0 resection (anatomical lobectomy or pneumonectomy with mediastinal lymph node dissection). * Postoperative pathological stage ypT\_anyN⁺M0 (residual nodal metastasis in mediastinal or hilar lymph nodes). * ECOG performance status 0-1. * Adequate hematologic, hepatic, and renal function per protocol-defined lab thresholds. * Able to start postoperative radiotherapy and/or PD-1 maintenance within 4-10 weeks after surgery (or after recovery from postoperative complications, as clinically appropriate). * Signed written informed consent. Exclusion Criteria: * Positive surgical margins (R1 or R2) or incomplete resection. * Prior thoracic radiotherapy that would overlap with planned treatment fields. * Active, uncontrolled infection or unresolved ≥ Grade 2 immune-related adverse events. * History of severe autoimmune disease requiring systemic immunosuppression. * Uncontrolled interstitial lung disease or significant pulmonary fibrosis. * Symptomatic or untreated central nervous system metastases at enrollment. * Any condition that, in the investigator's judgment, would compromise patient safety or protocol compliance.
