Summary
Brief summary (as posted)
For patients of GIST (Gastrointestinal Stromal Tumor), Imatinib has been widely used in GIST with KIT or PDGFRA 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 and other 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, plasma trough concentration and drug effect, the association between ADME-associated SNP, Target/Receptor/Pathway-associated SNP, trough concentration and TKI adverse effect. Furthermore, in vivo and in vitro research is also crucial for rational explanation for these clinical phenomenon.
