The Prevalence of Oncodrivers in Malignant Pleural Effusions Associated With Non-small Cell Lung Cancer: A Prospective Study.
Oncological treatment of patients with disseminated non-small cell lung cancer (NSCLC) is depending on the status of programmed death-ligand 1 (PD-L1), anaplastic lymphoma kinase (ALK) and epidermal growth factor receptor (EGFR), so called oncodrivers. These can be measured in pleural fluid, but the prevalence is uncertain. In a prospective study, the research team aim to measure PD-L1, ALK and EGFR in patients with pleural fluid cytology positive for NSCLC to report the prevalence. Also, the study will investigate if the chance of obtaining oncodriver status is depending on the volume analysed and how the lack of oncodrivers influence the following work-up.
• Age ≥ 18 years
• Pleural effusion known or suspected of association with NSCLC (pleural fluid cytology positive for cells from NSCLC)
• Patients must be able to give informed consent
