　　Researchers at the York Clinic in May in the United States recently reported that they "cured" an American woman with multiple myeloma who received ultra-high doses of measles virus treatment. However, the researchers also emphasized that this treatment is still in the early stages of human trials. According to the latest issue of the Mayo Clinic Journal, the 49-year-old woman's cancer had spread to her entire body before receiving treatment, and a tumor with a diameter of 3 cm had grown on her forehead. The measles virus therapy developed by the researchers selectively killed myeloma plasma cells. This woman maintained "complete relief" after a single injection for more than 6 months.

　　Another 65-year-old woman with multiple myeloma did not get the expected results after receiving the same treatment. However, the researchers say that imaging techniques clearly show that the injected measles virus still targets female myeloma plasma cells. It should be emphasized that the measles vaccine usually contains only 10,000 units of measles virus, and the two patients in this study have never been exposed to measles before. This effect is only visible when the number of virus is 100 billion units, and such a large amount of virus is enough to provide measles vaccine to 10 million people. The researchers said that until the two patients received the experimental treatment, there were no other treatment options for tumor expansion. Regarding the importance of this result, the researchers found that "viral therapy" is a method that uses viruses to infect and destroy cancer cells without damaging normal tissues. It can effectively treat deadly multiple myeloma. He pointed out that it conceptually illustrates what can be done.
