MUNICH, March 11 /PRNewswire-FirstCall/ -- Clinicians at the Rinecker Proton Therapy Center (RPTC) in Munichhave treated their 100th patient using advanced proton therapy systems supplied by Varian Medical Systems (NYSE: VAR). The landmark treatment comes just three months after a second treatment gantry was commissioned at the center, which offers advanced
These patients, requiring treatment for a wide range of cancers, have come from across Germany and 19 other countries, including Canada, Argentina, the UK and Switzerland. Among the first 100 patients have been several children, as proton therapy's ability to limit exposure to healthy tissue is particularly valuable in pediatric treatments.
A typical pediatric treatment involved a seven-year-old girl suffering from a malignant blastoma in the upper neck area. "The tumor was too large for surgery and had continued growing during chemotherapy, so proton therapy seemed the best treatment option," says Professor Manfred Herbst, medical director at RPTC. "She has tolerated the therapy extremely well – the tumor was obstructing her nose but her breathing has improved as the tumor has shrunk, and she had no difficulty in swallowing. Also, due to the unique properties of proton scanning we were able to spare the left parotid gland from exposure during treatment and she did not suffer from 'dry mouth,' where it is difficult to produce saliva. Her mother has reported that the girl has already become stronger and more active during the course of therapy."
Unlike conventional X-ray based radiotherapy that utilizes photons and electrons, proton therapy involves delivering heavier proton particles to destroy tumors. Proton therapy enables oncologists to improve dose control and limit exposure to healthy tissue while treating cancer and other indications. As a result, proton technology has moved from research facilities into active cancer treatment clinics such as RPTC.
Patients at RPTC are currently treated in two gantry rooms, each equipped to offer state-of-the-art pencil-beam proton scanning. When completed, the center will comprise a total of four gantry rooms and one fixed-beam room, the latter of which will specialize in treating delicate tumors such as small head, neck and eye cancers and tumors close to the spinal cord. The two additional gantry rooms are due to be ready for clinical treatment during 2010.
Dr. Joerg Hauffe, chief executive officer of ProHealth, the center's operating company, said RPTC benefits from being able to offer Varian's pencil-beam spot scanning delivery method, which offers distinct performance advantages for more precise dose distribution than is possible with other proton delivery systems. "We believe pencil-beam scanning is the best approach for patients because you can more easily and effectively shape the dose distribution as necessary and lessen exposure to critical organs such as the spinal cord, which is difficult to achieve using the standard scattering proton technique employed by most other proton centers," said Dr. Hauffe.
