Summary: Sometimes, a prostate biopsy underestimates how aggressive the cancer is. This study looked at ways to predict when the final surgery will find a higher-grade cancer than the initial biopsy. We analyzed 96 men who had both a biopsy and their prostate removed. We focused on factors like PSA (a blood test for prostate cancer), MRI scans, and biopsy results. We found that the extent of cancer involvement in biopsy cores, and to a lesser degree PSA density, were associated with upgrading risk to a more aggressive cancer at surgery. Using just these two factors, a simple statistical model predicted grade upgrading more accurately than more complex computer models. If confirmed in larger studies, this tool could help doctors identify patients who have more aggressive cancer than initially thought, so they can choose the best treatment.
