Lu-177-PSMA-617 vs Jevtana (cabazitaxel): which should I do next?

We saw recently (see this link) that of chemotherapeutic and hormonal medicines for treatment of metastatic castration-resistant prostate cancer (mCRPC), Jevtana (cabazitaxel) is the preferred third-line treatment after Taxotere (docetaxel) and Zytiga (abiraterone acetate) or Xtandi (enzalutamide). … READ MORE …

ADT and risk for COVID-19 infection?

Early in 2020, in the initial stages of the COVID-19 pandemic, there was a suggestion (based on data from a small Italian study) that men who were using androgen deprivation therapy (ADT) to manage their prostate cancer might be at lower than average risk for becoming infected with this virus. … READ MORE …

Two technologies have come together to allow for a new kind of radiation treatment known as simultaneous integrated boost (SIB), or, more informally, “dose painting.” … READ MORE …

SBRT for high-risk prostate cancer patients

As we have seen, stereotactic body radiation therapy (SBRT) is a preferred therapy for low- and intermediate-risk patients (see this link). It is effective, safe, convenient, and relatively inexpensive. However, its use for high-risk patients remains controversial. … READ MORE …

Whole pelvic salvage radiation may be better than precisely targeted lymph node salvage radiation

Last week, I looked at a retrospective study of metastasis-directed therapy (MDT) at the Mayo Clinic among oligorecurrent patients (see this link). … READ MORE …

The epidemiology of prostate cancer (2003-2017)

A recent report in the CDC’s Morbidity and Mortality Weekly Report (MMWR) may offer one of the best analyses of an increasing risk for diagnosis with and death from advanced forms of prostate cancer over the period from 2003 to 2017 (the last year for which we have accurate data from the SEER database). … READ MORE …

Long-term use of 5-ARIs in low-risk men on AS

Perhaps unsurprisingly, your sitemaster was a little distracted on March 9 this year (by both the start of the COVID-19 chaos and by his birthday) and so he utterly missed what appears to be a rather important paper on the use of 5α-reductase inhibitors (5-ARIs) in men on active surveillance (AS) for management of low-risk forms of prostate cancer.

Onvansertib in treatment of abiraterone-resistant mCRPC

We hear that an investigational drug called onvansertib — a so-called polo-like kinase 1 (PLK1) inhibitor — may have benefit in the treatment of men with metastatic, castration-resistant prostate cancer (mCRPC) who are showing early signs of progression on treatment with abiraterone acetate (Zytiga) + prednisone.

SBRT vs. EBRT in treatment of painful spine metastases

New data on this topic — from a Phase II/III clinical trial — have just been presented at the virtual annual meeting of the American Society for Radiation Oncology (ASTRO). Basically, the data from this study by Sahgal et al. indicated that 24 Gy (in two 12 Gy doses) of stereotactic body radiation therapy (SBRT) was more effective in the elimination of spinal pain in patients with metastatic cancer as compared to 20 Gy (in five 4 Gy doses) of conventional, external beam radiation therapy (EBRT).

The virtual prostate cancer patient

A new type of “educational” service has been brought to our attention that uses virtual reality (VR) systems allowing a number of opportunities for men to “talk” to a virtual prostate cancer patient about their own risks for prostate cancer and things like the risks and benefits of PSA testing. … READ MORE …
