CCTV.com News (international news): Since the day when human beings discovered cancer, the medical community has been making unremitting efforts to find a cure for cancer. Recently, scientists at the University Hospital of Leuven in Belgium said that their research has made important progress.
According to the medical journal Cell, Professor Peter cameri, who is in charge of anti-cancer research in Leuven University Hospital, has recently made an important breakthrough in finding new antibodies to inhibit tumor growth.
This research belongs to the emerging field of anti-cancer drug research and development, and its principle is: through related antibodies, cut off blood vessels to deliver nutrients and oxygen to tumors, thus inhibiting the growth of tumors. Professor cameri's research is simply to "starve" or even "starve" tumors by blocking the growth of related blood vessels.
At present, most of the anticancer drugs used in clinic are aimed at vascular endothelial growth factor, but most of these drugs are accompanied by serious side effects in chemotherapy. Professor cameri Ye and his research team found another new antibody, placental growth factor antibody, or PLGF antibody for short. It is believed that the antibody binds to placental growth factor in tumor, which blocks the way of placental growth factor binding to capillaries, reduces the nutritional supply of tumor, slows down the rate of cancer cell division, which is lower than the rate of immune system killing cancer cells, and will lead to obvious tumor shrinkage.
The researchers said that this antibody can not only fight against tumors with the antibody * * * that has been found, but also enhance the anti-cancer effect; At the same time, it has fewer side effects and can alleviate the pain of chemotherapy, which may be applied to pregnant women, children or patients with weak cancer alone.
Experts believe that the discovery of placental growth factor antibody marks a major breakthrough in the field of anti-cancer. Some cancer patients said that if the spread of cancer can be slowed down or stopped, and the life span of patients can be prolonged, it would be a great victory in itself. However, experts also stressed that the study has not yet entered the clinical trial stage, and the relevant results have yet to be tested.
