According to primary genotypes, the median PFS in GIST with KIT exon 11 mutation, exon 9 mutation, PDGFRA D842V mutation and wild type were 2.8 months (95% CI, 2.18‐3.42 months), 4.2 months (95% CI, 0.84‐7.56 months), 3.0 months (95% CI, 0.31‐5.70 months), and 5.0 months (95% CI, 3.309‐7.691 months), respectively. This evidence concerns the gene PDGFRA and gastrointestinal stromal tumor.
