Lung Cancer Patients Benefit from Faster Radiotherapy Treatment
Dec 16 2008
as a result of severe emphysema, was the first patient to receive the pioneering radiotherapy treatment at the hospital in early September.
"We normally use ultra-precise stereotactic radiotherapy in these cases and we have now treated more than 400 such patients in this way,"
said Dr. Ben Slotman, Chairman of the hospital`s Department of Radiation Oncology. "But RapidArc offers some real time-savings over
stereotactic radiotherapy and its use in this case is a real breakthrough for us and our patients." The pioneering treatment was delivered in less than 15 minutes versus the 30 to 45 minutes normally
needed by the team at VU University Medical Center to treat lungs with image-guided intensitymodulated radiotherapy (IMRT). The treatment
was delivered using six arcs, or rotations of the treatment machine around the patient. "We were very pleased with how the treatment
went," added Dr. Suresh Sunan, Professor of Clinical Experimental Radiotherapy. "The online patient setup using cone beam CT scans allowed direct visualisation of the tumour just prior to fast treatment delivery using RapidArc, all of which greatly increased the confidence of the treatment team in the precision of delivery. The high dose radiation area was restricted to the tumour and the surrounding healthy tissue and critical organs received very low doses.
Due to the high precision and the speed of treatment delivery, and the associated increase in patient comfort, RapidArc will eventually replace all `conventional` stereotactic treatments for early stage
lung cancer at our hospital."
