WebFeb 3, 2013 · Gene expression clusters define GIST subtypes. Self-organizing cluster analysis of the relative expression of 14 target genes relative to GAPDH identified five expression groups among 138 GIST specimens.

WebApr 25, 2024 · In the past 10 years, the remedy of GISTs has gradually been evolving from a one-size-fits-all scheme to targeted oncogene treatments for specific molecular GIST subtypes (Blay et al., 2024a). However, the effectiveness of targeted therapy varies among patients because its effectiveness depends on the genetic mutation profile of GIST tumor ... WebNo mutations are detected in 5-10% of tumors and those subtypes are called wild type GIST (WT).
