Immunotherapy has improved outcomes in patients with metastatic non-small cell lung cancer (NSCLC) without an actionable driver mutation, when compared to chemotherapy alone. Since 2018 immunotherapy agents were approved for first-line use either as a single-agent immunotherapy (ICI) or in combination as chemoimmunotherapy (CIT) for patients with metastatic NSCLC and programmed death ligand-1 (PDL1) score greater than or equal to 50%.
The addition of chemotherapy to immunotherapy is hypothesised to improve the immunogenicity of the tumour micro-environment and induce a more rapid tumour response. However the addition of chemotherapy risks greater toxicity.
There remain a limited number of international real-world analyses that assess characteristics influencing treatment selection and none in the Australian setting. There are no descriptive analyses of current practice for this cohort in Australia.
This study aims to administer a survey to clinicians in order to understand current clinical practice and treatment decision-making for driver-negative, metastatic NSCLC with PDL1 50% or greater.
