The best way to treat cancer that develops in the liver, is to perform surgery to remove this tumor. But when this proves impossible, other treatments are envisaged, like the chemotherapy, but also the direct destruction of the cancerous cells by the heat (probe microwaves, radiofrequences), by the cold (cryotherapy), by the local injection of ethanol. or by radioembolization. Among these treatments that are still under study to optimize their effectiveness, radioembilization - also referred to as selective internal radiotherapy, appears as a promising avenue that is the subject of numerous studies.
Since external radiotherapy of the liver is difficult, at the risk of being too harmful, poorly targeted, radioembolization appears as an interesting alternative. Its goal: to deliver rays via radioactive micro-beads injected into the liver, in order to destroy the cancer cells . In fact, these micro-beads are injected into the liver via the bloodstream and thus reach the tumor (s) to be treated.Radioembolization is today mainly used to treat certain liver cancers. This treatment is especially indicated for patients suffering from metastases to the liver (whose origin is colon cancer). This procedure, which is performed in the hospital in an interventional radiology department, is indicated in patients who can not be operated on.
It has been more than 10 years since this technique is under study and has already been used in many patients. At the ASCO 2015 (Chicago - USA) Specialized Congress in Oncology, interesting results were presented by Professor Peter Gibbs, Australian oncologist, when radioembolization is associated with chemotherapy.
