What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Wedge resectionProcedure or surgery
Wedge resection is a surgical procedure that is done to remove a wedge-shaped section of lung tissue, usually for treating lung cancer. A wedge resection is less invasive than some of the other surgical options used to remove lung cancer.
| Study group | Role | What they receive |
|---|---|---|
| Wedge resection | Experimental | Wedge resection is performed for early-stage lung cancer to remove a wedge-shaped section of lung tissue. Receives: Procedure: Wedge resection |

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Wedge resection in people with Lung Cancer and Wedge Resection, run by Fudan 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 11 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: opening soon, as of the sponsor's last update on 26 Oct 2023. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 Tong Li (+86 18813039287, litong_medical@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
5-year overall survival (time frame: 5 years). 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 NCT06102161, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2023; AzTrials last refreshed its copy on 7 Nov 2026.
