Elephants Cancer-Crushing Secrets May Someday Help People: THURSDAY.

Now, a group of researchers thinks it has found the elephant’s secret: an enormous stash of a tumor-suppressing gene that is also within people, only in very much smaller and less aggressive quantities. ‘Half of all men and a third of most women will establish cancer in their lifetime,’ said research author Dr. Joshua Schiffman, an investigator at the Huntsman Cancer Institute at the University of Utah. ‘The uncontrolled cell division and genomic instability that’s cancer is very much a disease of aging, because the older we get the less we’re able to repair damaged cells.’ Because elephants ‘are 100 occasions our size, and have thus many cells, and live for such a long time, it stands to cause that just by opportunity alone all elephants ought to be dying from cancer.Statistical Evaluation The trial was powered to determine whether PCI with the very best available medical therapy was superior to the best available medical therapy alone with regards to the primary end point at two years. Based on findings from previous studies and using binomial proportions, we estimated that the cumulative incidence of the primary end point at 24 months would be 12.6 percent in the PCI group18-20 and 18.0 percent in the medical-therapy group,3 corresponding to a relative risk reduction with PCI of 30 percent, and that with 816 sufferers in each combined group, the study could have more than 84 percent power to detect that relative risk reduction, at a two-sided type I error rate of 0.05.
