Real-world survival benefit of treatment with sipuleucel-T

So there are new, interesting data regarding the treatment of men with metastatic, castration-resistant prostate cancer (mCRPC) with sipuleucel-T (Provenge) as well as either or both of abiraterone acetate (Zytiga) and enzalutamide (Xtandi) — known generically as androgen-receptor signaling pathway inhibitors or ASPIs. … READ MORE …

Who actually dies from prostate cancer? Additional observations

Earlier today we reported on a recent publication based on data from the CaPSURE registry database, which stated that, among men enrolled in that database, men died sooner from their prostate cancer after they progressed to having metastatic disease over time (median survival, 2.4 years from onset of metastasis) than died from their prostate cancer if they were initially diagnosed with metastatic disease (median survival, 5.3 years). … READ MORE …

Who actually dies from prostate cancer?

Some readers are probably going to find this very hard to believe, but … according to a newly published study, men initially diagnosed with metastatic prostate cancer are actually less likely to die from their cancer than men who are initially diagnosed with non-metastatic disease but who progress to having metastatic disease over time. … READ MORE …

PSA doubling time and prognosis for men with nmCRPC

A report this week in Urologic Oncology has confirmed the importance of PSA doubling times in understanding risk for prostate cancer progression among men with non-metastatic, castration-resistant prostate cancer (nmCRPC). … READ MORE …

ADT + darolutamide extends overall survival in men with nmCRPC

According to a media release issued by Bayer a couple of days ago, the combination of androgen deprivation therapy (ADT) + darolutamide (Nubeqa) extends overall survival “significantly” in men with non-metastatic, castration-resistant prostate cancer (nmCRPC). … READ MORE …

Enzalutamide extends OS compared to an standard antiandrogen in ENZAMET trial, but …

The randomized, double-blind, Phase III ENZAMET trial was designed to investigate whether the combination of enzalutamide + standard androgen suppression had superior outcomes than a non-steroidal antiandrogen + standard androgen suppression in men with metastatic, hormone-sensitive prostate cancer (mHSPC). … READ MORE …

Long-term follow-up data from LATITUDE trial

Long-term follow-up data from the LATITUDE trial have now been published by Fizazi et al. in Lancet Oncology. … READ MORE …

Agent Orange and prostate cancer-specific survival on ADT

A newly published article in this month’s Journal of Urology has suggested that being exposed to Agent Orange and getting prostate cancer comes with better overall survival data than if one gets prostate cancer some other way. … READ MORE …

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 …
