Results of mutation analysis for the 13 assays for 43 NSCLC subjects.

For each subject the origin of the cytological material and the mutational status for each of the 13 assays are indicated. Only one subject (40) shows a discordance on a single assay (boxed cell), which may be explained from the commonly observed genetic divergence of metastasis from its primary tumor.‘P’, primary tumor; ‘M’, metastasis; ‘√’, concordance of wildtype result from mutation analysis between histology and cytology; ‘mut’, concordant samples with a somatic mutation; ‘−/+’, discordant result, mutation in the cytological and wildtype in the histological material; ‘−/?’, wildtype signal in the histology with discordancy in the cytological material because of low signal; ‘?/−’, Low signal in the histological material and wildtype signal in the cytology.
