Calypso Prostate Cancer Treatment
Targeted Prostate Cancer Radiation
Precise radiation, fewer side effects
In radiation treatment of prostate cancer, the goal is to deliver as much radiation to the affected area as possible, while minimizing radiation to surrounding healthy tissue and organs. After years in development, a breakthrough therapy called the Calypso Prostate Cancer System has come to the San Francisco Bay Area, along with the prospect of unprecedented benefits for prostate cancer patients.Dr. Constantine Mantz, radiation oncologist and lead investigator of the study, explains the significance of the findings: “When prostate cancer patients evaluate treatment options, their objective is to select the therapeutic approach that will cure the cancer while allowing them to remain as fully functional as possible. The Calypso System, which enables physicians to deliver increased doses of radiation directly to the tumor, while sparing the surrounding healthy organs from exposure, is fundamental to our overall approach of treating prostate cancer.”

How Calypso works
- During radiation treatment, a patient’s organs naturally move, and a doctor or radiation technician cannot predict which way or how much they move. As a result, other nearby organs and healthy tissue may receive radiation inadvertently.
- To accommodate this movement, a doctor using Calypso begins by implanting three tiny devices in the prostate. This is an outpatient procedure, similar to a biopsy, performed prior to radiation.
- These devices, each about the size of a grain of rice, are tracking devices called beacon transponders.
- Then, during radiation, the beacon transponders communicate with the Calypso System constantly. The transponders allow the Calypso System to track the precise location of the prostate tumor at all times. Subsequently, the tracking permits the precise focusing of safe radio-frequency waves on the tumor.
- The Calypso System allows the radiation oncologist overseeing the treatment to make quick, important decisions about each patient’s care.
