About this study
Official title: Elimination of PTV Margins Based on Online Adaptive Stereotactic Radiotherapy for Early-stage Non-small Cell Lung Cancer or Pulmonary Oligometastases: a Prospective, Randomized, Controlled Phase II Study
This study aims to explore the safety and efficacy of eliminating the PTV (planning target volume) margins based on online adaptive stereotactic radiotherapy for patients with early-stage non-small cell lung cancer (NSCLC) or pulmonary oligometastases.
Read the detailed description
This study aims to explore the safety and efficacy of eliminating the PTV expansion margin based on online adaptive stereotactic body radiotherapy (SBRT) for early-stage non-small cell lung cancer (NSCLC) or pulmonary oligometastases. In this study, patients will be stratified according to whether they have primary early-stage NSCLC, then randomly assigned in a 1:1 ratio to the study group or the control group. Patients in the study group will receive online adaptive SBRT (without PTV expansion margin), while patients in the control group will receive conventional standard SBRT. After the completion of treatment, patients will be followed up regularly to assess safety and efficacy.

| Study group | Role | What they receive |
|---|---|---|
| The study group | Experimental | Patients in the study group will receive online adaptive stereotactic body radiotherapy (without PTV expansion margin). The total dose will be 45-50Gy/3-4 fractions, administered once daily. Both FBCT and 4DCT will be acquired before initiating treatment at each fraction. Receives: Radiation: Online adaptive SBRT |

The total dose will be 45-50Gy/3-4 fractions, administered once daily. CBCT will be acquired before initiating treatment at each fraction. Receives: Radiation: Conventional SBRT |
What is being measured
The primary outcome is the main question the study is designed to answer.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Online adaptive SBRT and Conventional SBRT in people with Adaptive Radiotherapy and Stereotactic Body Radiotherapy, run by Sun Yat-sen University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 17 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Bo Qiu, Professor (+862087343031, qiubo@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of grade 2 or higher respiratory toxicity (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06542159, which also lists 15 linked publications.
Does a listing mean the treatment is approved or proven to work?
