Cancer Cured? Granulocytes Treatment Worked 100 Percent In Mice Work But Will It Work In Humans?

Scientists at Wake Forest University Baptist Medical Center are about to embark on a human trial to test whether a new cancer treatment will be as effective at eradicating cancer in humans as it has proven to be in mice.
The treatment will involve transfusing specific white blood cells, called granulocytes, from select donors, into patients with advanced forms of cancer. A similar treatment using white blood cells from cancer-resistant mice has previously been highly successful, curing 100 percent of lab mice afflicted with advanced malignancies.
Zheng Cui, Ph.D., lead researcher and associate professor of pathology, will be announcing the study June 28 at the Understanding Aging conference in Los Angeles.
The study, given the go-ahead by the U.S. Food and Drug Administration, will involve treating human cancer patients with white blood cells from healthy young people whose immune systems produce cells with high levels of cancer-fighting activity.
The basis of the study is the scientists' discovery, published five years ago, of a cancer-resistant mouse and their subsequent finding that white blood cells from that mouse and its offspring cured advanced cancers in ordinary laboratory mice. They have since identified similar cancer-killing activity in the white blood cells of some healthy humans....
...For the upcoming study, the researchers are currently recruiting 500 local potential donors who are 50 years old or younger and in good health to have their blood tested. Of those, 100 volunteers with high cancer-killing activity will be asked to donate white blood cells for the study. Cell recipients will include 22 cancer patients who have solid tumors that either didn't respond originally, or no longer respond, to conventional therapies. The study will cost $100,000 per patient receiving therapy, and for many patients (those living in 22 states, including North Carolina) the costs may be covered by their insurance company. There is no cost to donate blood. For general information about insurance coverage of clinical trials, go to the American Cancer Society's web site at

"If the study is effective, it would be another arrow in the quiver of treatments aimed at cancer," said Mark Willingham, M.D., a co-researcher and professor of pathology. "It is based on 10 years of work since the cancer-resistant mouse was first discovered."...
