Name: cancer cell lines establishmentDescription: Detection of epithelial growth factor receptor (EGFR) mutation in malignant pleural effusion of lung cancer patients and cancer cell lines establishmentType: Other
Single Group Assignment
There is one SNP
In-frame deletions in exon 19 centered on codons 756 to 750 make up 45~50% of mutations, and another 35~45% consist of the missense mutation leucine to arginine at codon 858 (L858R) in exon 21 (8, 9, 10). --- L858R ---
It is interesting that exon 19 deletion have increased response and survival with TKIs compared with L858R cases (10, 13, 14). --- L858R ---
This is in contrast to the natural history of patients, where those with exon 19 deletions appear to have shorter survival than those with L858R (8). --- L858R ---
