Utilisation des microsphères biodégradables en thérapie anti-cancéreuse expérimentale. Application chronopharmacologique

We describe the initial experimentations which show that is possible to chronomodulate the cisplatin liberation out of some microspheres. The goal is to generate, inside one tumeur embolished by those cisplatin loaded microspheres, some concentration peaks at the best tolerance time. The cancer is than more hit, by the high local anticancer drug concentration, and doses chronomodulations preserve the patient by following his tolerance. The experimentation on cancerous mice show that this technique could lead to great survival increases. Such a protocol might usefuly improve the anticancer therapy.
