Over the past decades, treatment options in advanced non-small cell lung cancer (NSCLC) patients without oncogenic drivers have been limited to cytotoxic chemotherapies with poor survival outcomes.¹ Although patients’ overall survival (OS) has been prolonged with the current standard of care (SoC) (i.e. pembrolizumab with or without chemotherapy) in recent years, the clinical outcomes are still suboptimal.^2,3 Dual immunotherapy, which brought substantial survival improvements across multiple malignancies such as advanced melanoma, sheds light on the further advance of metastatic NSCLC (without driver mutations) management.⁴ The combination of nivolumab (NIVO) and ipilimumab (IPI) with or without chemotherapy has demonstrated superior survival benefits in these patients, leading to the regulatory approval from the United States (US) Food and Drug Administration (FDA).^5,6 More recently, the efficacy of durvalumab and tremelimumab plus chemotherapy (D + T + CT) in treatment-naïve metastatic NSCLC patients has also been evaluated in the POSEIDON trial.⁷ In a webinar organized by the Hong Kong Precision Oncology Society, Dr. Melissa L. Johnson presented the encouraging data from POSEIDON and discussed the latest advances of immunotherapy in metastatic NSCLC. Dr. Au, Siu-Kie Joseph also shared his expert insights on the new POSEIDON data and discussed their impacts on the local clinical practice in an interview with Omnihealth Practice.

Lung cancer is the leading cause of cancer-related deaths worldwide with 2.09 million cases annually.¹ In Hong Kong, lung cancer was responsible for 27.1% of all cancer deaths in 2017.² Among all lung cancers, non-small cell lung cancer
