Can Gene Expression Profiles Be Used for Cancer Diagnosis and Prognosis?
Yes, gene expression profiles can be utilized for cancer diagnosis and prognosis. Technologies like microarrays and RNA sequencing allow for the comprehensive analysis of gene expression patterns. Specific gene expression signatures can distinguish between different cancer types, predict patient outcomes, and guide treatment decisions. For instance, the Oncotype DX test analyzes the expression of a panel of genes to predict the likelihood of breast cancer recurrence.
