To treat or not to treat? That is the question researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) hope to answer with a new advance that could help doctors and their cancer patients decide if a particular therapy would be worth pursuing.
Berkeley Lab researchers identified 14 genes regulating genome integrity that were consistently overexpressed in a wide variety of cancers. They then created a scoring system based upon the degree of gene overexpression. For several major types of cancer, including breast and lung cancers, the higher the score, the worse the prognosis. Perhaps more importantly, scores could accurately predict patient response to specific cancer treatments.
The researchers said the findings, to be published Wednesday, Aug. 31, in the journal Nature Communications, could lead to a new biomarker for the early stages of tumor development. The information obtained could help reduce the use of cancer treatments that have a low probability of helping.
