Researcher at Memorial Sloan Kettering Medical Center are reporting great success with an experimental gene therapy to treat advanced leukemia.
All 16 patients in the study had a type of leukemia that is difficult to treat because there is a high relapse rate.
Doctors took the patients' immune cells and modified them to recognize and destroy cancer cells. They say 88 percent of the patients achieved complete remission.
Researchers say the treatment made the patients very sick at first, as if they had a bad infection, but that went away as the cancer cells were killed off.
Doctors hope the experimental therapy may one day treat other cancers, including breast and colon cancer.
