Tumor size and genomic risk in localized prostate cancer.

Purpose: Unlike many other cancers, measurement of primary prostate tumor size has no defined role in the management of localized prostate cancer. Here, we assess whether prostate tumor size is associated with aggressive tumor biology using biomarkers of genomic risk.

Materials And Methods: We abstracted or imputed tumor size from the primary pathology reports of prostate cancers incorporated in The Cancer Genome Atlas.
