Quick radiation blasts may ease lung cancer symptoms
NCT ID NCT04384146
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested the safety of a special radiation schedule called Quad Shot for people with stage IV non-small cell lung cancer who are also receiving chemotherapy or immunotherapy. The Quad Shot delivers radiation in just 2 days per cycle, up to 3 cycles, to make it easier to fit with other treatments. 41 participants completed the study to see if this approach is safe and tolerable.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Quad Shot radiation therapy
- What this could lead to
- If successful, this could offer a shorter, safer radiation schedule for advanced lung cancer patients, potentially easing symptoms without disrupting their ongoing treatment.
- What could go wrong
- This is an early phase I trial with only 41 participants, so results may not apply to all patients. There are risks of side effects like esophagitis or pneumonitis.

Inclusion Criteria: * Histologically confirmed non-small cell lung cancer with metastatic disease detected on cross-sectional imaging with a plan for one of the following systemic therapies: * Carboplatin/paclitaxel * Carboplatin/paclitaxel/pembrolizumab * Carboplatin/pemetrexed * Carboplatin/pemetrexed/pembrolizumab * Pembrolizumab (single agent or in combination with other regimens in this list) * Cisplatin/pemetrexed * Cisplatin/pemetrexed/pembrolizumab * Pemetrexed/pembrolizumab * Pemetrexed * Nivolumab (single agent or in combination with other regimens in this list) * Ipilimumab/nivolumab * Carboplatin/etoposide * Carboplatin/etoposide/atezolizumab * Cisplatin/etoposide * Cisplatin/etoposide/atezolizumab * Durvalumab (single agent or in combination with other regimens in this list) * Atezolizumab (single agent or in combination with other regimens in this list) * Patients eligible for the systemic therapy regimens notes * Patients with Stage IV NSCLC who have symptomatic (defined by patient-reported cough, dyspnea, or hemoptysis) or near-symptomatic (determined radiographically to be threatening the airway, esophagus or vasculature) centrally located. * KPS ≥ 60 * Age ≥ 18 years. * Able to provide informed consent. * Patients at reproductive potential must agree to practice an effective contraceptive method. Exclusion Criteria: * Previous radiotherapy to the intended treatment site that precludes developing a treatment plan that respects normal tissue tolerances. * Serious medical co-morbidities precluding radiotherapy. * Pregnant or breast-feeding women.
