Clinical and Molecular Findings in Patients With Cervical/Supraclavicular Metastasis From Non-small-cell Lung Cancer (NSCLC)

Patients with evidence of enlarged and/or PET positive cervical and/or supraclavicular lymph nodes suspected of being metastasis from lung cancer will be submitted to the biopsy from this location.

Patients without evidence of enlarged and/or PET positive cervical and/or supraclavicular lymph nodes will be submitted to the biopsy considered less invasive and effective based on imaging data and clinical health status.
