Abstract
Background: Non-small cell lung cancer (NSCLC) is a predominant cause of oncological mortality in the United Kingdom. There is a diverse spectrum of therapeutic options available, such as chemotherapies, targeted therapies and immunotherapies, which have significantly advanced patient prognoses. However, despite these advancements, there is an escalating concern regarding the potential cardiotoxic effects associated with these treatments. Objectives: This study aimed to explore the association between non-small cell lung cancer treatments and cardiotoxicity. Methods: A pharmacovigilance study was conducted utilising the UK Yellow Card System. The proportional reporting ratio (PRR) and reporting odds ratio (ROR) were calculated to detect signals. Results: Among the 56 shortlisted NSCLC drugs, the total number of adverse events reported was 128,214 with 6133 reports being cardiovascular adverse reactions. Among all the drugs analysed, alectinib demonstrated the highest ROR and PRR values, indicating the strongest signal for potential cardiovascular adverse events. Conclusions: This result was comparable to previous studies which also detected a signal of alectinib related to cardiovascular events using the WHO pharmacovigilance database, VigiBase. However, clinical studies demonstrated that alectinib largely improved progression-free survival (PFS) and overall survival in patients. Therefore, it is important to continue monitoring the real-world use of alectinib, so that a benefit-risk balance can be maintained.
