Doctor Veneta Petrova received her Medical degree from the Medical University – Sofia. She has been working at the Military Hospital from 5 years now in the Oncology ward. Along with the practice, Dr. Petrova is doing her Ph.D. on microsatellite instability in colorectal cancer, which will be the topic of her lecture at the IBCS 2017. For the first time, cancer immunotherapy does not depend on the location but on the tumor’s genetics. This means that pharmaceutically developed antibodies against microsatellite instability have been approved for treatment of all adult and pediatric patients with metastatic, microsatellite insatiability-high solid tumors who have no satisfactory alternative treatment options.
