NEUROENDOCRINE PROSTATE CANCER: An Adverse Development in Advanced Disease — Which Largely Has Flown Under the Radar.

Neuroendocrine prostate cancer (NEPC) is a form of the disease which, as best currently understood, arises from standard adenocarcinoma in a process termed “transdifferentiation.” This transformation develops in advanced stages of prostate cancer—usually in metastatic CRPC, and is thought to result as an adaptation to the selective pressure of androgen deprivation. It’s usually seen after prior therapy with, for example, abiraterone and/or enzalutamide and is one source of resistance to these agents.

The goal of active surveillance (AS) is to delay treatment, avoiding its associated adverse effects for as long as appropriate, while ensuring that selective delayed intervention will still result in a good outcome. This management strategy has been under development for more than 20 years. It has been increasingly accepted as an appropriate option for men with low-risk disease, but further refinement is required in patient selection and monitoring strategy.
