Value of F-18 FDG PET/CT for the Prediction of EGFR Mutation in Lung Cancer Patients

* Globally, lung cancer cases and deaths are rising. In 2018, GLOBOCAN estimated 2.09 million new cases (11.6% of total cancer cases) and 1.76 million deaths (18.4% of total cancer deaths). It is the most frequent cancer and cause of cancer death in men. * Epidermal growth factor receptor (EGFR) mutations are the second most common oncogenic driver event in non-small cell lung cancer (NSCLC) and classical activating mutations are well defined as strong predictors for good clinical response to EGFR tyrosine kinase inhibitors (EGFRi). * Over the last decade, the introduction of tyrosine-kinase inhibitors (TKIs) has showed a remarkable paradigm shift in the treatment of non-small cell lung cancer (NSCLC). However, genetic testing is sometimes unavailable. * Data from previous studies that have investigated the value of F-18 FDG PET/CT for predicting EGFR status are conflicting.
