Radioimmunotherapy has been utilized in other cancers as well
At the time, Knox and Goris began to experiment with different ways to administer the therapy so that it would prove more effective and less toxic to the body. They studied part of the antibody that is able to make out CD20 and improve delivery to the tumor, thus reducing patients’ chances of viewing the new protein as a foreign substance. Since the immune responses from radioimmunotherapy are considered harmful, the experts looked for ways in which the proteins could make it to the cancer cells and attach themselves to them, before they have a chance to be excreted from the body. They even studied the use of radioimmunotherapy in solid tumors, such as pancreatic cancers and colon cancers.
