Retinoblastoma Loss in Cancer: Casting a Wider Net

Capturing both genomic and nongenomic mechanisms of retinoblastoma gene dysfunction has potential to improve risk stratification and patient selection for biomarker-driven therapy. A 186-gene expression signature is capable of identifying Rb loss across cancer types, providing a new framework for assessing Rb dysfunction based on transcriptome data.
