Is time to biochemical failure a good surrogate endpoint for overall survival?

For many years researchers have been trying to identify so-called “surrogate” endpoints that can be used to predict overall and prostate cancer-specific survival with high accuracy. … READ MORE …

Race and survival of men after docetaxel-based treatment for mCRPC

A new paper in the Journal of Clinical Oncology has just reported that the overall survival (OS) of black and white men diagnosed with metastatic castration-resistant prostate cancer (mCRPC) seems to be near to identical after treatment with docetaxel or a docetaxel-containing regimen. … READ MORE …

Survival of men with metastatic, castration-resistant prostate cancer

There has been regular discussion here and elsewhere about the degree to which new forms of therapy have impacted patient survival since the original approval of docetaxel for treatment of metastatic, castration-resistant  prostate cancer (mCRPC). … READ MORE …

MFS as an endpoint in clinical trials

Earlier this year, two drugs (apalutamide/Erleada and enzalutamide/Xtandi) were each approved for the treatment of non-metastatic, castration-resistant prostate cancer (nmCRPC) based on the use of metastasis-free survival (MFS) as the study endpoint in clinical trials. … READ MORE …

MFS as a new endpoint in prostate cancer drug development

An article by staff at the U.S. Food and Drug Administration (FDA) in this week’s New England Journal of Medicine (NEJM) addresses the use of metastasis-free survival (MFS) as the primary endpoint in the trial that led to approval of apalutamide (Erleada) earlier this year. … READ MORE …

Adjuvant mitoxantrone + prednisone + ADT in treatment of high-risk prostate cancer

About 25 years ago the addition of the combination of mitoxantrone + prednisone to androgen deprivation therapy (ADT) was the first form of chemotherapy ever approved for the treatment of metastatic, castration-resistant prostate cancer. … READ MORE …

Escalated radiation dose doesn’t improve 8-year overall survival in intermediate-risk men (but does it matter?)

Last week, we saw that escalated dose did not improve 10-year overall survival in high-risk men (see this link). The latest published findings of the randomized clinical trial (RTOG 0126) prove that 8-year overall survival was not improved in intermediate-risk men who received a higher radiation dose. … READ MORE …
