tumor genomic complexity score
A quantitative metric that summarizes the overall burden of genomic alterations and chromosomal instability within a tumor sample.
Full Definition
The tumor genomic complexity score is a composite metric designed to quantify the overall level of genomic disruption in cancer samples, incorporating multiple types of alterations including point mutations, copy number changes, structural variants, and chromosomal rearrangements. Different scoring systems may weight various alteration types differently based on their functional impact or clinical significance. These scores help classify tumors along a spectrum from genomically quiet to highly complex, which correlates with prognosis, treatment response, and underlying biological processes. High complexity scores often indicate defective DNA repair mechanisms and may predict sensitivity to specific therapeutic approaches such as immunotherapy or DNA damage response inhibitors. Standardization of complexity scoring remains an active area of development in precision oncology.
Usage
Usage note: Emphasize composite nature; distinguish from single-metric assessments.
