Prostate Cancer

The Decipher prostate cancer gene-expression classifier can predict patients’ risk of metastasis and prostate cancer-specific mortality using biopsy specimens prior to radical prostatectomy or radiotherapy plus androgen deprivation.

“Liquid biopsy” analyses of circulating tumor DNA from blood samples potentially reveal prognostic information about metastatic castration-resistant prostate cancer, and might point the way for development of new targeted treatments.

A long-term study found that adding 24 months of antiandrogen therapy with bicalutamide to salvage radiation therapy increased overall survival and prostate cancer–specific survival compared with placebo in men who underwent radical prostatectomy.

The use of multi-parametric magnetic resonance imaging could allow more than a quarter of men with high prostate-specific antigen levels to avoid undergoing transrectal ultrasound-guided prostate biopsy.

In prostate cancer patients, a PSA nadir value of > 0.5 ng/mL after radiation therapy and androgen deprivation therapy can identify patients at a high risk of death.

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.

Among cancer patients with bone metastases, administration of zoledronic acid every 12 weeks did not increase the risk of skeletal events over 2 years compared with the standard dosing of every 4 weeks.
