Immunotherapy To Stop Prostate Cancer

One of the most common diseases to hit the male population is prostate cancer. While some cases seem harmless as they develop so slow, about 30 percent of those who've been diagnosed carry a more aggressive type of prostate cancer. Meaning to say, the cancer has already started spreading throughout the body.

Based on studies, the cancer grows more rapidly in the presence of testosterone. That is why hormone treatments help in stopping the production of testosterone, if not outright removal of the testicles by surgery. If these treatments don't work, chemotherapy comes in next.

As scientists continue to find ways to treat prostate cancer, a new option is being developed through immunotherapy, a treatment that allows the immune system to fight against cancer cells with the help of a vaccine. In an experiment involving 125 male adults, those who were treated with the PRSTVAC-VF vaccine lived eight to nine months longer than those who were given placebo.

While it is still too early to conclude about the validity of the experiment, the success of this phase 2 stage should lead to an experiment with a larger population to further test the effectiveness of the vaccine.
