WHAT IS CALYPSO?
Tumors tend to change position within the body for various reasons. During radiation therapy, changes in size and position of a tumor can expose the healthy tissue surrounding the treatment area, to unnecessary, harmful radiation. CALYPSO is a form of IGRT (Image Guided Radiation Therapy) that uses “electromagnetic transponders” that cancer doctors implant into the body, to monitor a tumor’s precise location throughout cancer treatment. Calypso is FDA approved to treat prostate cancer, and may eventually be used to treat other types of cancer as well.
WHAT PATIENTS CAN EXPECT:
During an outpatient procedure, cancer doctors use small needles to implant tiny transponders, similar in size to a large sesame seed, around the treatment area. During subsequent radiation therapy treatments, the CALYPSO transponders actively communicate the exact location of the tumor.
• CALYPSO has the potential to cause less damage to the healthy tissue during treatment, which often leads to fewer side effects.
• Because the precise location of the tumor can be tracked, higher doses of radiation can be administered, allowing for a shorter treatment period, in addition to higher cure rates.
• A patient can now relax normally during radiation treatments and no longer needs to maximally fill his bladder and be uncomfortable during radiation, due to this advanced technology.
• The Calypso System can treat tumors that are harder to reach, or next to a healthy organ, with less risk of damage being caused to organs.
