Clinical trial results to date show that men with visceral CRPC metastases do not benefit from ipilimumab, while their counterparts with bone- or node-only metastases do. This suggests that visceral metastases should be a stratification factor for future immunotherapy clinical trials.

In this review, we will discuss the current status of several anti–PD-1 and anti–PD-L1 antibodies in clinical development and their direction for the future.

During the past decade, targeted therapeutics have changed the landscape of cancer therapy with bold brush strokes, but the resulting images are still unclear. As we enter into the second decade of targeted therapy, our increased understanding of tumor biology together with cancer genomic sequencing tools will clearly show the way forward. It is imperative that we use these fine brushes, not only to improve precision, but in the end to realize the art of medicine.
