Malignancy
YES
To investigate clinical benefit of liquid biopsy by measuring a somatic cell mutation such as EGFR gene mutation from peripheral circulating free DNA (tumor-specific circulating cell-free DNA: cfDNA) derived from plasma and DNA derived from tumors collected before and after treatment with EGFR-tyrosine kinase inhibitor (EGFR-TKI) using digital PCR and next-generation sequencer in patients with EGFR gene mutation-positive non-small-cell lung cancer.
Others
Clinical benefit of liquid biopsy by measuring the somatic cell mutation such as EGFR gene mutation.
Detection of EGFR gene mutation from cfDNA collected before and after treatment with EGFR-TKI in patients with EGFR gene mutation- positive non-small-cell lung cancer.
Detection of a biomarker about EGFR-TKI tolerance.
Coincidence ratio of detection of EGFR gene mutation between tissue samples and cfDNA.
Association between the clinical background including a presence or absence of T790M gene mutation and the prognosis.

Not applicable |
Male and Female
1)Patients with EGFR gene mutation (exon 19 deletion, L858R, G719X, L861M, T790M, etc) -positive non-small-cell lung cancer determined with a histological diagnosis or cytodiagnosis.
2)Patients with treatment plan of EGFR-TKI alone or combination therapy including EGFR-TKI. In addition, plasma samples of patients before treatment are stored at -80 degrees Celsius even if after the start of treatment.
3)Patients with more than 20 years.
4)Patients providing written informed consent.
1) Patient with positive HBs antigen or HVC antibody.
2) Patient with definite positive HIV antibody (need not for examination).
3) Any other patients who are regarded as unsuitable for this study by the investigators.

Peripheral blood (7ml, EDTA-2Na) is collected before treatment with EGFR-TKI (from -4 weeks to treatment start day) and at 12 weeks, at 24weeks, at 36 weeks, after every 12 weeks (the allowance day: 1 week) after treatment start and at disease progression (within 2 weeks after PD confirmation).
The submission of tumor samples is not essential.
However, the following samples are submitted to investigate the correlation between tumor sample and cfDNA about having T790M gene mutation or not, in the cases that one of the following samples (no limit at collection time) are stored before start of EGFR-TKI treatment, or a re-biopsy is carried out from the progression of disease during treatment with EGFR-TKI.
/Six pieces of slide specimens which performed slicing to a 4-5 microns thickness of the paraffin embedded specimen.
/One piece of prepared slide (Papanicolaou stain) used for a cytodiagnosis.
/Twenty ml (10mLx2) of malignant pleural effusion was centrifuged (1400g for 10min at room temperature), and stored two pellets at -80 degrees Celsius after removal of a supernatant. The supernatant is not removed too much (leave around 1cm).
/DNA extract (samples after EGFR gene mutation examination)
/Cell block
