Vaccine Protects Against Prostate CancerNew research at the University of Southern California in Los Angeles indicates that an experimental vaccine can offer long-term protection against prostate cancer in mice genetically prone to the disease. The senior investigator said in a statement that trough this early vaccination mice can have life-long protection against a disease they were destined to have. The new vaccine stimulates an immune action against PSCA, good vaccine target because it is overly expressed in prostate cancer tumor, but not very disseminated in other tissues. Investigators reported in the journal Cancer Research that they administered a PSCA-based vaccine to mice 8 weeks old and already having pre-cancerous prostate lesions. Vaccination was linked with a strong immune response. At 12 months, 90 percent of the vaccinated mice were still alive, while all of the control animals had either large cancer tumors and had either died. Researchers feel that with just two shots, the vaccine will prime immune cells to be on the lookout for any cell that over-expresses PSCA and this is a very promising approach, but human are needed to confirm the safety and efficacy of this vaccine strategy.
