About this study
Official title: Concordance Between Intraoperative Frozen Section and Postoperative Pathology in Diagnosing the IASLC Grades and Guiding the Surgical Procedure of Lung Adenocarcinoma: a Multi-center Prospective Study

The goal of this clinical trial is to confirm the concordance rate between intra-operative frozen section pathological diagnosis and post-operative paraffin embedded pathological diagnosis, and use this result to guide surgical treatment for early stage (cT1N0M0) lung adenocarcinomas.
- Being tested
- Surgical resection

Surgical resectionProcedure or surgery
Surgical resection of lung adenocarcinoma. Wedge resection, segmentectomy or lobectomy will be performed according to each patients' condition.
| Study group | Role | What they receive |
|---|---|---|
| Study group | Clinical T1N0M0 lung adenocarcinoma patients eligible for surgery. Receives: Procedure: Surgical resection |
What is being measured
The primary outcome is the main question the study is designed to answer.

Measured: 2 years
Secondary outcomes (5)
Concordance rate
Concordance rate between intraoperative frozen section and postoperative paraffin embedded pathology in making the diagnosis of pleural invasion and lymph node invasion.
Measured: 2 years
Concordance rate
Concordance rate between intraoperative frozen section and postoperative paraffin embedded pathology in making the diagnosis of IASLC grades of lung adenocarcinoma
Measured: 2 years
Concordance rate
Concordance rate between intraoperative frozen section and postoperative paraffin embedded pathology in making the diagnosis of spread through air space (STAS).

Recurrence-free survival (RFS) is defined as the time from date of curative surgery to the time of recurrence or death, whichever comes first.
Measured: 5 years
Overall survival (OS)
Overall survival (OS) is defined as the time from date of curative surgery to the time of death of any reason.
Measured: 5 years

Questions about this trial
What is this clinical trial studying?
An observational study of Lung Adenocarcinoma and Surgical Procedure, Unspecified, 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 6 inclusion and 4 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: finished, as of the sponsor's last update on 3 Sep 2024. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Concordance rate (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 3 Sep 2024.
