Rhode Island Hospital first in US to treat kidney tumor with new device using electrical pulses
Date:1/9/2009

ovide new avenues of treatment for patients. Cryoablation, radiofrequency (RFA) and microwave ablation (MWA) all use intense heat or cold that destroys cells. The destroyed material may actually stay in the body for some time. The electrical fields used in the new IRE cause defects in cell membranes. Those cells within the targeted tissue then die within six hours of treatment, while the critical structures surrounding the targeted site are preserved and can then assist the body in removing the dead cells.

Damian Dupuy, MD, is a pioneer in image-guided ablation for the treatment of solid tumors, including RFA, MWA, cryoablation and now IRE. First approved by the FDA in 1997, RFA is a minimally invasive technique that uses heat to destroy tissue. A number of hospitals around the country have adopted the technique, most often to destroy liver tumors.

Dupuy, who is also a professor of diagnostic imaging at the Warren Alpert Medical School of Brown University, has broadened the applications of image-guided ablative therapies to successfully combat lung, kidney, adrenal, thyroid and bone cancer. Since 1997 more than 2,000 patients have undergone image-guided ablation at Rhode Island Hospital, the largest use of this technique in treating malignancy in North America. Other newer techniques such as combination therapies of ablation and external beam radiation or internal radiation seeds have been pioneered by Dupuy at Rhode Island Hospital. He is now leading National Cancer Institute-funded trials in the use of ablation for the treatment of tumors, and has published over 150 publications and given over 90 invited presentations nationally and internationally in the field of imaging and minimally invasive cancer therapies.
