This multicenter pilot observational study aims to assess the feasibility of introducing liquid biopsy at an early stage of the diagnostic pathway for patients with suspected advanced non-small cell lung cancer (NSCLC).
Liquid biopsy is a minimally invasive blood test that can detect tumor-related genetic alterations in circulating nucleic acids. The study will evaluate whether this approach can provide molecular information more rapidly than standard tissue-based testing and how closely the results obtained from blood samples match those obtained from tumor tissue.
Approximately 70 adult patients with radiological evidence of locally advanced or metastatic lung cancer will be enrolled. Participants will undergo a blood draw for liquid biopsy and will continue to follow the standard diagnostic pathway, including tissue biopsy or cytological sampling when indicated.
The results generated within the study are intended for research purposes and will not replace standard diagnostic procedures or independently determine treatment decisions. The findings will be used to identify practical and methodological issues and to support the design of future clinical studies on the plasma-first approach.
