Active surveillance is an excellent alternative to surgery or radiation in patients with low-risk cancers. However, the current methods of ascertaining whether a patient harbors a low-risk cancer are flawed.

In this peer-to-peer discussion, Dr. Loeb and Dr. Choyke discuss new developments in active surveillance for prostate cancer.

The concept of multiparametric MRI comes at an important time in the history of prostate cancer screening. It is a method that provides anatomic information about the location, number, size, and risk of prostate cancers. It permits more accurate targeted biopsies that will improve the quality of tissue obtained, thereby reducing the rate of upstaging associated with random biopsies.
