According to a recent report in the Yomiuri Shimbun, Yamaguchi University professor Tadakatsu Sakai and other scientists tried to inject iron chelator directly into the livers of patients with advanced liver cancer. After receiving the injection for about two months, two of the 10 patients with advanced liver cancer who participated in the trial saw their tumor tissues shrink, and three others stopped getting worse. Iron chelator can bind to iron ions in the body and be excreted with urine, so the injection of iron chelator can effectively reduce the concentration of iron ions in the body. Because iron ions are an important raw material in the development of tumor tissues such as liver cancer, a decrease in the concentration of iron ions in the body can have a therapeutic effect on liver cancer. Scientists say that current clinical trials show that de-ironing has the potential to be a new treatment for liver cancer. However, because of the great risk of the body losing iron ions, Japanese scientists believe that the accurate use of this method still needs more trial data. The above results of Japanese scientists have been published in the American “New England Journal of Medicine”.
