EXTRACELLULAR VESICLES TO DELIVER THERAPEUTIC OR DIAGNOSTIC DRUGS

The present invention applies to the medical field and, in particular, to tumor diagnosis or treatment . Surgical therapy in oncology remains the most effective treatment for the eradication of solid tumors. The success of the therapy depends almost exclusively on the surgeon's ability to resect the tumor margins. This ability is currently not easily standardized and is entrusted to the experience and tact ile/visual sensitivity of the surgeons themselves. The use of highly selective diagnostic compounds would allow the surgeon to visualize the margins of the tumor within healthy tissue during the surgical procedure either directly or through imaging methods .
