THURSDAY, March 16 (HealthDay News) -- Capsaicin, the component that gives jalapeno peppers their heat, may also kill prostate cancer cells, a new study suggests.

Initial experiments in cancer cells and mice show that capsaicin causes prostate cancer cells to undergo a kind of suicide. Researchers speculate that, in the future, pills containing capsaicin might be used as therapy to prevent prostate cancer's return.

According to their report, capsaicin caused almost 80 percent of prostate cancer cells in the mice to die. In addition, prostate cancer tumors treated with capsaicin were about one-fifth the size of tumors in untreated mice.

'Capsaicin inhibits the growth of human prostate cancer cell in Petri dishes and mice,' said lead researcher Dr. H. Phillip Koeffler, director of hematology and oncology at Cedars-Sinai Medical Center and a professor of medicine at the University of California, Los Angeles. Based on the findings, Koeffler believe the next step is a trial to see if it works in patients with prostate cancer.

The report appears in the March 15 issue of Cancer Research.

Capsaicin probably has several effects, Koeffler said. Most noticeable is its effect in blocking NF-kappa Beta, a molecular mechanism that promotes cancer cell growth, he noted.

In addition, capsaicin also was effective against leukemia, and might be effective in slowing or preventing the growth of other cancers as well, he added."
