New treatment targets prostate cancer
Researchers at the Prostate and Breast Cancer Research Program at Monash University claim to have found a treatment using oestrogens to treat castrate-resistant cells in recurrent prostate cancer.
They used a drug that is developed to activate selectivelyand specifically the beta oestrogen receptor in the prostate, which not only inhibits cancergrowth but also kills off cancer cells that are resistant to the conventionalandrogen deprivation therapy.
The researchers report discovering how this compound,working through the beta receptors, targets a small but important population ofcells in the tumour.
They made their discovery in animal models and thenreplicated laboratory results using human cells and tissues from patients withprostate cancer.
