People treated with external radiation therapy may experience some side effects, called late effectssuch as the development of second cancersmonths or years after treatment. It is also common to combine radiotherapy with surgery, chemotherapy, hormone. Current radiotherapy techniques, such as conformal radiotherapy and intensity modulated radiotherapy (IMRT), accurately shape the radiotherapy beams to fit the cancer. This is necessitated by the reliance on consistency with diagnostic imaging studies, such as Computed Tomography (CT), that are acquired in a horizontal position and are required for radiation dose calculations. Most men who receive radiation as their initial treatment wont experience a recurrence of their cancer. But efforts to create such drugs have met with limited success, Dr. Kunos explained, because it isnt enough that toxins be brought close to a cancer cell. Nuclear imaging tests, such as positron emission tomography (PET), sometimes use weakly radioactive compounds linked to molecules that bind to specific targets on the surface of cancer cells. Importantly, Dr. Pierce said, these effects, as judged by both patients themselves and their physicians, also did not differ between the sequential and concurrent boosts.
