A cancer therapy trial based on the work of Zheng Cui is presently underway in Florida: "About 75% of US population living today will not die of cancer. It is not uncommon that some people remain cancer-free into their 80s and 90s, even if they are regularly exposed to environmental carcinogens such as air pollutants, cigarette smoking, etc. A frequently asked but unanswered question is why these individuals do not get cancer. There has been a recent report of a colony of cancer-resistant mice developed from a single male mouse that unexpectedly survived challenges of lethal cancer cell injections. In these so-called spontaneous regression/complete resistant (SR/CR) mice, cancer cells are killed by rapid infiltration of leukocytes, mainly of innate immunity. This highly effective natural cancer immunity is inherited and mediated entirely by white blood cells. Moreover, this cancer resistance can be transferred to wild type mice through the transfer of various immune cell types including granulocytes. This observation raises the possibility that infusion of white blood cells, particularly cells of innate immunity, is a viable anticancer therapy in humans as well. This proposed trial will test whether white blood cell infusions from healthy unrelated donors can be used to treat cancer. The trial is designed to determine whether responses can be seen in cancer patients after infusion of HLA-mismatched white cells from healthy donors."
