The vitamin D saga … another data analysis

Nearly a year ago now we reported data from one relatively large study that suggested there was no direct connection between intake of vitamin D (in its 25-hydroxy vitamin D formulation) and risk for prostate cancer.

Salvage cryotherapy as second-line treatment after first-line radiation therapy

We really have no idea what the “best” way is to treat men with progressive disease after first-line radiation therapy.

Oral taxane enters Phase II clinical trial for mCRPC

The Prostate Cancer Clinical Trials Consortium (PCCTC) has initiated a Phase II clinical trial of an oral taxane known as tesetaxel in the treatment of metastatic, castration-resistant prostate cancer (mCRPC).

What if we could sequence whole prostate cancer genomes?

There has been little doubt over the years that prostate cancer was a genetically complex disease. No one has ever seriously thought that prostate cancer was the result of a single change in the DNA of the individual patient. Now we finally have some proof!

Is CCP testing really the prognostic tool we need?

A new report just published on line in Lancet Oncology is suggesting that the cell cycle progression (CCP) score — a measure of the levels of expression of selected genes that are important to cell growth — may be an important indicator of risk for more aggressive types of prostate cancer.

IxMP as second- or third-line chemotherapy for mCRPC

A report on a Phase II study from the Department of Defense-funded Prostate Cancer Clinical Trials Consortium has suggested that ixabepilone + mitoxantrone + prednisone may have clinically significant activity as a form of second-line chemotherapy in the management of men with docetaxel-refractory, metastatic, castration-resistant prostate cancer (mCRPC).

Outcomes following EBRT and an SBRT “boost” for localized prostate cancer

New data from the radiotherapy group at the University of Califronia, San Francisco suggests that stereotactic body radiation (SBRT) can be used to deliver a “boost” of focused radiation after external beam radiation therapy (EBRT). High dose rate (HDR) brachytherapy has also been used in this way in the past.

AstraZeneca stops second trial of zibotentan

According to a media release issued by AstraZeneca earlier today, the company has stopped a second clinical trial of their endothelin receptor antagonist zibotentan because “zibotentan monotherapy was unlikely to meet its primary efficacy endpoints … and therefore unlikely to benefit patients with non-metastatic CRPC.”

Limited value of immediate, adjuvant ADT in men with pT3b prostate cancer

New data published by clinical researchers at the Mayo Clinic have suggested that there is no overall survival benefit associated with adjuvant hormone therapy after surgery in men with pathological T3b disease.

Major league sports and prostate cancer … a challenge

So here in the USA, Major League Baseball has been a long-time supporter of a significant initiative to spread awareness of prostate cancer.

Most prostate cancers aren’t rare diseases — but some are!

February 28, 2011 is Rare Disease Day — here in America and around the world. Sponsored by EURORDIS and by other national rare disease organizations (including the National Organization of Rare Disorders here in the USA), Rare Disease Day is held on the last day of February every year.

Androgen supplementation and risk for prostate cancer

A new paper from a research team in Seattle probably has limited relevance to our understanding of the real risks associated with androgen supplementation and subequent diagnosis of prostate cancer (or other prostate disorders) — even though it was a randomized, double-blind clinical trial.

The appropriate selection of patients for active surveillance

A recent French study nicely illustrates the very real problem associated with the selection of the best candidates for active surveillance and the exclusion from active surveillance of patients who probably would be better served by immediate treatment.

Researchers claim four-gene panel can identify high-risk prostate cancer

According to an article on the Wall Street Journal web site today, some Boston-based researchers associated with a company called Metamark Genetics are claiming to have isolated a combination of four genes that might be able to identify early stage prostate cancer that will evolve into an aggressive and potentially deadly form of the disease.

ACS projects annual incidence, mortality data among African Americans

The American Cancer Society has just released its biannual report entitled Cancer Facts & Figures for African Americans 2011-2012. The report suggests that there will be 35,110 new cases of prostate cancer and 5,300 prostate cancer-specific deaths among the African American community in 2011.
