SKP2 High Expression, KIT Exon 11 Deletions, and Gastrointestinal Bleeding as Predictors of Poor Prognosis in Primary Gastrointestinal Stromal Tumors
BACKGROUND AND AIMS Considering the indication of adjuvant therapy, the recurrence risk for primary gastrointestinal stromal tumor (GIST) after surgery needs to be accurately estimated. However, current risk stratification schemes may still have room for improvement. This study seeks to analyze prognostic factors for primary GISTs from 3 aspects, including clinicopathological parameters, immuno...
متن کاملC-kit gene mutation in human gastrointestinal stromal tumors.
AIM To investigate the significance of c-kit gene mutation in gastrointestinal stromal tumors (GIST). METHODS Fifty two cases of GIST and 28 cases of other tumors were examined. DNA samples were extracted from paraffin sections and fresh blocks. Exons 11, 9 and 13 of the c-kit gene were amplified by PCR and sequenced. RESULTS Mutations of exon 11 were found in 14 of 25 malignant GISTs (56%)...
متن کاملThe KIT Exon 11 Stop Codon Mutation in Gastrointestinal Stromal Tumors: What Is the Clinical Meaning?
BACKGROUND/AIMS Gastrointestinal stromal tumors (GISTs) strongly express a receptor tyrosine kinase (RTK, c-KIT-CD117) harboring a KIT mutation that causes constitutive receptor activation leading to the development and growth of tumors; 35% of GISTs without KIT mutations have platelet-derived growth factor receptor alpha (PDGFRA) mutations, and the type of mutation plays an important role in t...

متن کاملKIT gene mutations in gastrointestinal stromal tumor.
Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract. It arises in the stomach, small intestine, colon, rectum and esophagus. KIT gene mutation is a feature of GIST, in addition to PDGFRA gene mutation. KIT gene mutations have been observed to be involved in the development of GIST, its recurrence after surgery and chemotherapy resistance in G...
