Abstract

V originále

Background Single nucleotide polymorphisms can create a genetic microenvironment in some tumors that affects the course of treatment, resistance, etc. Whether single nucleotide polymorphisms have an impact on gastrointestinal stromal tumor (GIST) development and disease progression is not yet accurately verified.KITSNP(M541L)in exon 10 correlates with a worse prognosis of many cancers. The impact ofKITSNP(M541L)in GISTs is relatively unknown and, therefore, its analyses could have potential in patient therapy and could provide more detailed information on tumor character, clinical presentation, or tumor behavior in treatment. Aim The aim of the study was the analysis of the biological and clinical significance of theKITSNP(M541L)polymorphism in exon 10. Materials and methods Paraffin sample tissues were obtained from the National GIST Register in Martin. Retrospective samples from 177 GIST patients were divided into several groups. Detection of SNP(M541L)was performed by Sanger sequencing. Statisitical analyses were performed to determine the prevalence ofKITSNP(M541L)in the Slovak GIST cohort, to search for correlation betweenc-KITstatus and clinicopathological, molecular and biological data. Results Overall, 29 samples out of 177 showedKITSNP(M541L)polymorphism. Conclusion Our results do not support the association betweenKITSNP(M541L)and increased risk of relapse in localized primary GISTs. Additionally, we found a positive correlation betweenKITSNP(M541L)occurrence and earlier onset of relapse inPDGFRaand WT subgroup of GISTs.
