MRI Targeted Biopsy is Better for Detecting High-Risk Prostate Cancer
According to a study in the January 27 issue of JAMA, targeted MRI/ultrasound fusion biopsy was associated with increased detection of high-risk prostate cancer compared to a standard biopsy technique.
The targeted MRI biopsy maximizes the ability to detect high risk cancers by insuring the needles are hitting the prostate, instead of randomly sampling the area. This approach may also avoid the potential harm of detecting low risk cancer, which is often clinically insignificant and unlikely to cause problems for the patient.
The study showed that an MRI guided biopsy had a 30 percent increase in detection of high-risk prostate cancer however it also showed a 17 decrease in the detection of low-risk prostate cancer.
