Vaccine for prostate cancer was proved safe and effective to use after passing several tests.
Based on research, this vaccine could give hope to people that suffering from metastatic prostate cancer because it can activate the immune system to that could fight the disease. This vaccine was developed in order to activate the immune system to produce anti-antigens and attack cancer cells that could sustain a longer life for the patients.
“The main objectivity of this study was to determine whether the vaccine is safe or will even worsen prostate cancer. It is a very safe vaccine,” said research team leader who is also Director of Urology at the University of Iowa David Lubaroff.
He also said that investigators still observe if the vaccine could result in immune system response to prostate specific antigen (PSA).”We found that 68-70% of patients tested with the vaccine showed a PSA response. We are very pleased that we can detect immune system response in these patients.”
The early stage of the results from this vaccine trials will be presented at the annual meeting of American Urological Association in Florida, USA.
In this study, approximately 32 people who develop metastatic prostate cancer given PSA vaccine. All of them are given varies doses of vaccine and has been observed for 12 months.
A total of 57% of them survive longer. In fact 48% of them can survive two times longer than previous predictions. From the results of this vaccine trial, the longest patients can survive are up to six years.
From these three results, David Lubaroff study team will begin the second phase of the research in the near future.
Meanwhile, Professor and Expert Urology Vanderbilt University Bruce Roth still not sure if the vaccine would be a vaccine that can be used continuously. “I think what can be proved from this study is the safety of the vaccine. But it is very different when we talk about the efficiency of this vaccine,” he said.
However, Bruce Roth thought that the early stages of the test results of this PSA vaccine is a good sign.
“I think this discovery is a breakthrough after waiting for about 35 years. This theory is very good compared to the last few decades because of various therapeutic vaccines that sounds great does not match the results we expected,” he added
