[An approach to individualised therapy of non-small cell lung carcinoma (NSCLC)--relevance of molecular predictive and prognostic factors]

Abstract

The treatment of patients with non-small cell lung carcinoma (NSCLC) is guided by results from clinical studies. Data about molecular changes in the tumour are not used (up to now) to decide for an individualised, tumour-tailored therapy. High-throughput technologies and modern analytical methods (e. g., microarrays) lead to exponentially increasing knowledge about genetic changes in the cells and the interaction of proteins. This results in the discovery of molecular factors with high predictive (prediction of tumour response) and prognostic (prediction of survival) value in NSCLC. Among these are ERCC1, RRM1 and some receptor tyrosine kinases. Preliminary data of prospective studies have shown promising results for the selection of specific drugs, when these tumour markers were analysed. Therefore, this review focuses on the actual value of molecular markers for decision-making in the adjuvant and palliative setting and their probable future introduction into clinical practice.
