Vitamin E May Help Fight Prostate Cancer

BRISBANE, Australia, Oct. 20 (UPI) — An Australian researcher suggests a new vitamin E treatment could improve prostate cancer survival rates.

Dr. Patrick Ling and colleagues at Queensland University of Technology in Australia found a particular constituent of vitamin E called tocotrienol or T3 can successfully kill off the prostate cancer stem cells believed to promote tumor regrowth.

“Currently there is no effective treatment for metastatic prostate cancer, because it grows back after conventional therapies in more than 70 percent of cases,” Ling said in a statement. “But with gamma-tocotrienol, Queensland University of Technology researchers have found a better way to treat prostate cancer, which has the potential to inhibit recurrence of the disease.”

Ling and colleagues conducted animal trials for a study that found gamma-tocotrienol fed to mice in water completely inhibited tumor formation in more than 70 percent of the animals implanted with prostate cancer cells and considerably reduced tumor regrowth in the remainder. In contrast, 100 percent of the control group had tumors reform.

The study is published in the International Journal of Cancer.
