4 new drugs will change prostate cancer care
Date:2/16/2012

After a decade and a half of near stagnation, four new drugs could help make advanced prostate cancer a chronic illness instead of a terminal disease, a leading Colorado prostate cancer expert says.

"It's not just chemotherapy. The drugs have different and innovative methods of action. One is a bone protective agent; another's a more effective hormone agent; another is radiotherapy; and the final one is the first drug tested for cancer immunotherapy," says E. David Crawford, MD, investigator at the University of Colorado Cancer Center and head of urologic oncology at University of Colorado Hospital.

"Even without the addition of any more drugs, we may now have the tools that in combination will allow us to extend the survival prognosis of a prostate cancer patient long enough to make prostate cancer a disease a patient is more likely to die with than from," Crawford says.

Along with Thomas Flaig, MD, Crawford describes these advances in prostate cancer treatment in a recent review for the journal Oncology.

First is the drug Denosumab, which Crawford says, "has three uses in protecting the bones of prostate cancer patients." It can prevent bone fractures in patients with existing bone metastasis; it can prevent osteoporosis in patients whose calcium is depleted as a side-effect of hormone therapy; and (pending FDA approval) it has been shown to hold off the occurrence of bone metastasis for an average of four months in patients whose spiking PSA scores predict the likely onset of bone involvement.

Second is the drug Alpharadin, which is one of a novel and exciting class of "radiopharmaceuticals" drugs that emit radiation and allow doctors to precisely deliver radiation to tumor sites. In the case of Alpharadin, it emits alpha rather than beta particles, which allows more precise tumor targeting of bone metastasis sites with less collateral damage to surrounding bone marrow.

Third, the drug Prostvac is
