There was a radical change in the first-line management of advanced NSCLC with negative genetic oncological drive in the last 5 years. Immune checkpoint inhibition is currently recommended for such a group of patients by major international guidelines devoted to lung cancer, as long as there is no contraindication. The recommendations came as a single agent of immune checkpoint inhibitor, combination of an immune checkpoint inhibitor with chemotherapy with an optional anti-angiogenic agent, or combination between two different immune checkpoint inhibitors; based on the level of expression of programmed death-ligand 1 in the tumour microenvironment and the type of immune checkpoint inhibitor is intended to be used. IMpower150 was a clinical trial that illustrated the effectiveness of the addition of Atezolizumab (immune checkpoint inhibitor) to chemotherapy and Bevacizumab (anti-angiogenic agent) in treatment naïve advanced non-squamous NSCLC patients with no genetic aberrations. In the same trial, there was no significant difference between chemotherapy plus either Atezolizumab or Bevacizumab. Moreover, Atezolizumab experienced other disappointing results in different clinical trials in NSCLC and other malignancies such as triple-negative breast cancer when combined with chemotherapeutic agents that require corticosteroids as pre-medications during therapy. This review evaluates the synergistic anti-neoplastic effect of immune checkpoint inhibitor and anti-angiogenic agent in NSCLC which presented in IMpower150 by Atezolizumab and Bevacizumab, especially this combination is the preferred option for other malignancies such as hepatocellular carcinoma and renal cell carcinoma. Additionally, the review overlooks the impact of corticosteroids on Atezolizumab in different clinical trials, particularly in NSCLC.
