Targeting Cancer and disease at the Cellular Level
“I think they’re [radiopharmaceuticals] going to transform radiation oncology in the next 10 to 15 years.”

Radioisotopes are used in “nuclear medicine,” a term which includes radiology practices at most major hospitals. Nuclear medicine is routine throughout the United States and much of the world. Anyone who has ever received an MRI or had their cancer treated with radiation oncology is a beneficiary of the power of nuclear medicine. There are more than 40 million nuclear medicine procedures performed each year around the world.
When injected in very small quantities into a patient, radioisotopes act as tiny tracers or flashlights. This allows tumors to be seen using medical imaging, such as PET and SPECT scans. By providing a picture of what’s going on inside the body, radioisotopes help health care professionals diagnose diseases and guide treatment decisions.
Increasingly, pharmaceutical makers are developing new drugs (radiopharmaceuticals) capable of delivering the cancer-killing power of radioisotopes directly to tumors while leaving the surrounding healthy tissue intact. Like a puzzle piece, these drugs attach only one way – directly to the proteins associated with the cancer – for maximum efficiency.

Use cases and studies
This image shows a prostate cancer patient. The spots in the Pre-treatment image are cancerous growths.
To treat this patient’s cancer a radioisotope-based pharmaceutical was administered.
Multiple rounds of treatment (Month 0-4) produced a successful effect. The cancer no longer appeared on image scans by month six. (Image adapted from source)
