A Retrospective Pharmacogenomics Research of EGFR-TKIs,Gefitinib and Erlotinib, in NSCLC Patients Treatment
Study Details
Study Description
Brief Summary
For patients of advanced NSCLC (non small cell lung cancer) , Individualized cancer therapy has been widely accepted since the success of crizotinib administration based on EML4-ALK fusion gene detection and gefitinib and erlotinib administration based on EGFR-TKIs sensitive mutations.From clinical points of view ,individual differences often occur between different patients, leading diverse effect in ADR and drug effect.Meanwhile ,the drug effect and adverse drug reaction was significantly influenced by the pharmacokinetic factors and pharmacodynamic factors.In this research ,we try to establish a more sensitive method to detect sensitive mutations in plasma and discover the correlation between somatic and germline mutations , trough concentration and EGFR-TKI drug effect, the association between ADME-associated SNP ,trough concentration and EGFR-TKI adverse effect .Furthermore, in vivo and in vitro research is also crucial for rational explanation for these clinical phenomenon.

Detailed Description
The ADME-associated SNPs included are CYP3A4,CYP3A4,CYP1A1,CYP2D6, ABCB1,ABCG2 and so on .The somatic mutations included are EGFR ,K-RAS ,ALK and so on

Arms and Interventions

---|---|
sensitive group; resistant group sensitive patients were defined as patients reached CR or PR after first month administration,SD after first three months administration. resistant patients were defined as patients reached PD after first month administration and first three months administration |
Outcome Measures
Primary Outcome Measures
- Progression free survival [The length of time from either the date of diagnosis to that patients diagnosed with the disease are still alive]
Excluding clinical deterioration without evidence of objective progression according to the Response Evaluation Criteria In Solid Tumors (RECIST), or death from any cause.
Secondary Outcome Measures
- Number of patients with objective response and adverse events [one month, three month]
Objective responses (complete response plus partial response) and disease control (objective response plus stable disease ≥6 weeks) were established according to RECIST.And adverse events was established according to NCI-CTC .
Other Outcome Measures
- Number of patients with ADR [one month, three month]
Such as rash
