Zusammenfassung
Background: Acquired resistance in NSCLC with activating EGFR mutations has been defined by Jackman et al. The molecular mechanisms have been studied in small series of patients: in about 50% of cases, T790 M mutation confers acquired resistance, in 25% c-Met amplification. Other as of yet unknown mechanisms might also play a role. Here we present the acquired resistance mechanisms in a cohort of 16 patients (out of 33 pts.) with activating EGFR mutations treated with TKI and identified at our center. Treatment methods and outcome are also described. Methods: 161 consecutive patients (s. abstract Halbfass et al.…
