Primary Outcomes

Time on Treatment With Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR-TKI)

Not applicable - Clinical evaluation: The uncommon Epidermal Growth Factor Receptor (EGFR) mutational status had become available after Progression on conventional second-line therapy. Erlotinib was given as state of the art second-line therapy in 2014, and an EGFR mutation was clinically suspected due to the Long-Lasting response. However, due to the unavailability of tumor tissue, this could be proven only after liquid biopsy had subsequently become available at the center in 2016. For the Sequencing cohort second-line treatment start is initiated by the beginning of the therapy with Osimertinib.
