Molecular Analysis of Circulating Cell-Free DNA from Lung Cancer Patients in Routine Laboratory Practice

Circulating cell-free DNA (cfDNA), which is isolated from blood plasma, represents a noninvasive source for the detection of mutations conferring resistance against epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors in non –small-cell lung cancer patients. In advanced disease stages, performing regular biopsies is often not possible because of the general health condition of the patients. Furthermore, a biopsy of a single tumor lesion or metastasis may not reflect the heterogeneous genotype of the tumor and its meta stases.
