Prostate cancer vaccine that uses virus similar to "small pox" can help patients with prostate cancer who had not been worse or it can be treated anymore, can live longer, researchers from the United States.
The vaccine was given the name "prostvac-VF" and currently being developed by BN Immuno Therapeutics, the firm's office biotechnologi Bavarian Nordic division.
Tests conducted on 125 patients with prostate cancer the level of "advanced" is immune to the drugs show they are able to live more than eight months or longer than those who did not receive treatment with the vaccine, said Dr. Philip Kantoff of the Dana-Faber Cancer Instiutute and Harvard Medical School in Boston, who led the study.
"The average cancer patient porstat lasted up to two years," Kantoff said in a telephone interview. "While that last up to three years, 30 percent of those who got the vaccine is still alive," he explained.
He argues, a broader study with more number of patients who were being prepared this year.
Study results, as reported in several meetings to discuss the problem of cancer a few months ago, has been described in detail in the Journal of Clinical Oncology.
Prostvac take a different approach from the vaccine that was developed earlier by the company that meproduksi Dendreon prostate cancer vaccine called Provenge. " Both are called "therapeutic vaccines" that treat disease with different forms of vaccines used to prevent infection.
Dendreon vaccine using immune system cells of patients who can manipulate them to better fight cancer.
Prostate cancer is the second leading cause of death for American men after lung cancer, with a ratio of more than 192 thousand cases diagnosed in 2009 and 27 thousand of them died, according to the testimony of the "American Cancer Society" Reuters quoted.
Green tea
Meanwhile, from a study quoted by Reuters also mentioned that green tea can slow the progression of prostate cancer.
The researchers mention that the active compounds in green tea is known to slow the progression of prostate cancer.
In the research found that some capsules are filled with green tea extract called "polyphenols" can lower levels of several proteins that so far causes tumors to grow.
Jim Cardelli from Louisiana State University Health Sciences Center in Shreveport and some of his colleagues tested 26 prostate cancer patients aged between 41 to 68 years.
Some patients showed a significant reduction in the level or almost 30 percent, said Cardelli.
Some side effects reported, but liver function remained normal patient, he said.
"This research is still early. Green tea can prevent cancer growth is faster, but still not tea extract can remove the tumor," he said.
However, the results of this study is in addition to traditional therapy information is good enough, besides chemoterapi or radiation, he said.
