Whole exome sequencing in relapsed or refractory childhood cancer: case series

Authors:

Abstract
Background: The prognosis for relapsed or refractory childhood cancer is approximately 20%. Genetic alterations are one of the significant contributing factors to the prognosis of patients. Objective: To investigate the molecular profile of relapsed or refractory childhood cancers in Thai cases. Methods: The study design is a descriptive study of patients NCOR2 , COL6A3 , TP53 , and SMAD4 genes. These alterations were found to be associated with tumor aggressiveness. Conclusion: This study is the first one to demonstrate genetic alterations by using WES in relapsed or refractory childhood cancer in Thai cases.
