Disease Spotlight: Prostate Cancer

Researchers found that a positive target of MRI led to a threefold increased risk for Gleason Grading Group (GGG) upgrading after radical prostatectomy in patients with low prostate cancer risk.

The use of actinium-225 PSMA radioligand therapy led to PSA level decreases of at least 50 percent in 57 percent of patients and a median progression-free survival rate of 7.9 months in patients with metastatic castration-resistant prostate cancer (mCRPC), according to newly published research.

A model that combines multiparametric MRI findings with clinical factors may enhance the accuracy of predicting clinically significant prostate cancer and significantly reduce unnecessary systematic prostate biopsies in biopsy-naïve patients.
