Overall Survival by Genotype. When calculated from the time of diagnosis, patients with wild-type GIST/SDH deficiencies or KIT exon 11 mutations did better than other types. The long survival times for wild-type GIST/SDH deficiencies in this series may reflect a high percentage of pediatric-type GIST patients. The relatively short survival time noted for PDGFRα mutations should be interpreted with caution given the small numbers and short follow-up.
