Zusammenfassung
Mit dem EGFR Tyrosin-Kinase Inhibitor Gefitinib (Iressa™) steht ein neues Therapieprinzip
für die Behandlung des nicht-kleinzelligen Bronchialkarzinoms zur Verfügung. Neueste
Forschungsarbeiten tragen zu einem besseren Verständnis der Grundlagen der molekularen,
zielgerichteten Therapie (Molecular Targeted Therapy, MTT) bei und erlauben es, die
bisher vorliegenden Ergebnisse zur klinischen Aktivität von Gefitinib neu zu interpretieren
und erstmalig prädiktiv Anhaltspunkte für geeignete Patienten-Subgruppen bei der Therapieentscheidung
zu selektionieren.
In der vorliegenden Arbeit werden drei Kasuistiken vorgestellt, an denen aufgezeigt
wird, dass vor dem Hintergrund neuer Ergebnisse der translationellen Forschung mit
Gefitinib eine wirksame, neue Substanz für die Behandlung chemotherapie-resistenter
nicht-kleinzelliger Bronchialkarzinome zur Verfügung steht.
Abstract
The EGFR-inhibition via tyrosine-kinase-inhibitor gefitinib (Iressa™) constitutes
a new way to treat non-small-cell lung cancer. Recent research results enable us to
better understand the basics of molecular targeted therapy (MTT). These results are
helpful to re-interpret the clinical results obtained so far for gefitinib and to
consider for the first time in a predictive manner factors for the selection of patients
suitable for therapy.
Three case reports are presented in this paper which illustrate that - with view to
the results from translational research - the use of gefitinib offers an efficient
new therapeutic modality for the treatment of chemotherapy-resistant non-small-cell
lung cancer.
