Early Changes in Positron Emissions Tomography (PET/CT) Scan as Predictors of Clinical Outcome in NSCLC Treated With EGFR Tyrosin Kinase Inhibitors (TKI)

Erlotinib, an anti-cancer agent targeting the epidermal growth factor receptor (EGFR), is an active treatment of patients with non-small cell lung cancer (NSCLC). Effect of treatment is primary seen in patients harboring a mutation in the EGFR. However, 10-15% of patients does not harbor a mutation but respond as well. Identifying these patients is a problem and methods are lacking. Studies have shown that an early 18F FDG-PET might can predict response and outcome in these patients, but further studies are needed to confirm these findings.
