Study summary

This study is one of Eastern Cooperative Thoracic Oncology Projects (ECTOP-1014). 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.

What researchers measure

Primary outcomes

  1. Concordance rate

    Concordance rate between intraoperative frozen section and postoperative paraffin embedded pathology in making the diagnosis of lung adenocarcinoma subtypes according to the WHO classifications.

    Time frame: 2 years

Secondary outcomes

  1. Concordance rate

    Concordance rate between intraoperative frozen section and postoperative paraffin embedded pathology in making the diagnosis of pleural invasion and lymph node invasion.

    Time frame: 2 years

  2. Concordance rate

    Concordance rate between intraoperative frozen section and postoperative paraffin embedded pathology in making the diagnosis of IASLC grades of lung adenocarcinoma

    Time frame: 2 years

  3. Concordance rate

    Concordance rate between intraoperative frozen section and postoperative paraffin embedded pathology in making the diagnosis of spread through air space (STAS).

    Time frame: 2 years

  4. Recurrence-free survival (RFS)

    Recurrence-free survival (RFS) is defined as the time from date of curative surgery to the time of recurrence or death, whichever comes first.

    Time frame: 5 years

  5. Overall survival (OS)

    Overall survival (OS) is defined as the time from date of curative surgery to the time of death of any reason.

    Time frame: 5 years

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2022 to primary completion in Jun 2024, 29 months.

Of 36 observational studies under Adenocarcinoma of Lung, half reached primary completion within 65 months of starting (the median), counting those still running; a quarter within 29 and three quarters within 65. This study's 29 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 3, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
