Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT04939324). This is a study registration, not published results. Lead sponsor: University Hospital, Limoges. Recruitment status: COMPLETED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 30 participants (ACTUAL). Conditions: Lung Cancer, Exosomes, Non Small Cell Lung Cancer. Interventions: BIOLOGICAL: Blood samples at 2 sites: peripheral vein and tumor-draining vein. Primary outcome measures: Evaluate size distribution, concentration and molecular profiling of pulmonary vein exosomes at inclusion , 36 months. Brief summary: This is an observational prospective single-center study of 30 patients operated for early-staged non-small cell lung cancer. The main aim is the analysis of molecular profiling of exosome with a sample in tumor-draining vein in order to identify prognostic molecular characteristics associated with cancer recurrence after surgery.
