Genomic instability of tumor cells has been associated with a poor prognosis. However, impaired DNA repair pathways leading to genomic instability are also described to increase tumor sensitivity to DNA damaging agents. A comprehensive Genomic Change Index (GCI) as an indicator of defective DNA repair is proposed as a potential predictor of cytotoxic chemotherapy (chemo) response. Cell-free tumor DNA (cftDNA) has the potential to provide minimally invasive patient specific biomarkers to monitor tumor burden (liquid biopsy).
