About This Topic
Genetic heterogeneity in cancer is defined as the occurrence of genetic variation between tumors (inter tumor) and/or within individual tumors (intra tumor) partly due to genomic instability. The genomic instability may arise due to increased mutation rates, chromosomal instability, and microsatellite instability, exposure to mutagens such as smoking, UV rays and radiation. Each of these causes may have a significant impact on cancer genomes resulting in diversity within a tumor that may lead to different clinical outcomes and response to therapies. Recent cancer genomic studies, based on approaches such as multi-region profiling or ultra-deep sequencing have revealed varying degrees of genetic heterogeneity in different tumor types.Understanding tumor heterogeneity has been highlighted as a critical area for translational cancer research.
In this special issue of OBM Genetics, we have chosen topics that highlight the causes and implications of genetic heterogeneity in cancer of different types, methods to identify genetic heterogeneity in cancer, tackling genetic heterogeneity and suggest treatment strategies. Overall, this issue provides a complete understanding of the genetic heterogeneity driven by genomic instability, ways to limit genetic heterogeneity and tackle drug resistance in cancer.
