Varian completes RapidArc therapy in France

Radiation therapy developer Varian Medical Systems of Palo Alto, CA, announced the completion of treatment for the first patient in France using its RapidArc intensity-modulated radiation therapy (IMRT) system.

A 60-year-old patient with prostate cancer was treated at the CRLC Val D'Aurelle - Paul Larmarque cancer center in Montepellier. The IMRT treatments with the RapidArc system required only 75 seconds, compared to 12-14 minutes with conventional IMRT, according to Varian. The faster treatment times help improve precision by reducing the time for anatomical structures to move, a problem in treating tumors in the pelvic region.

The RapidArc system targets radiation beams at a tumor while making one continuous rotation around the patient, delivering optimal treatment dose to the tumor while sparing normal surrounding tissue.
