To detect resistance gene from serially collected plasma DNA in non-small cell lung cancer harbouring EGFR activating mutation who are being treated with EGFR TKIs by using castPCR method.
Name: EGFR TKIs (gefitinib, erlotinib, afatinib, et al)
Description: To evaluate the efficiency of castPCR method for detection of resistance genes, especially, T790M mutation from serially collected plasma DNA in non-small cell lung cancer patients harboring EGFR activating mutation who are being treated with EGFR TKIs
Measure: detection of resistant gene Time: 24 monthsAllocation: Non-Randomized
Single Group Assignment
There are 2 SNPs
