生物谷報(bào)道：Mount Sinai綜合癌癥中心成為紐約唯一使用諾力刀（NOVALIS）手術(shù)系統(tǒng)治療脊椎癌的醫(yī)院,。
NOVALIS是最先進(jìn)的三維動(dòng)態(tài)適形調(diào)強(qiáng)放射治療系統(tǒng)，這是繼常規(guī)放射線治療后的最新一代放射治療技術(shù)。它采用立體定位技術(shù),，對(duì)腫瘤組織進(jìn)行精確的三維定位,，采用計(jì)算機(jī)治療計(jì)劃設(shè)計(jì)系統(tǒng)精確設(shè)計(jì)最佳療程,，高能加速器產(chǎn)生能量可以調(diào)整的光子束和電子束,，通過(guò)自動(dòng)控制射線形狀和調(diào)節(jié)射線強(qiáng)度分布，按照預(yù)先設(shè)計(jì)的治療程序,，以高精密度,、大劑量、聚焦式照射腫瘤區(qū)域,，使腫瘤周?chē)恼＝M織和器官減少放射線的照射,，因此顯著地提高腫瘤被照射的劑量，減少正常組織照射的劑量,，可提高腫瘤控制率和患者生存率,，減少放療并發(fā)癥,，改善病人生存質(zhì)量。
由于射線聚集的高劑量區(qū)形狀與腫瘤形狀一致,，腫瘤周?chē)?a href="http://hnhlg.com/news/list-54.html" target="_blank">健康組織和器官的劑量迅速衰減,，使腫瘤組織與健康組織間形成銳利的劑量梯度差異，因此可以達(dá)到無(wú)須開(kāi)刀即可精確切除腫瘤的效果,。
Mount Sinai綜合癌癥中心的醫(yī)師Isabelle Germano表示,，希望可以利用這種最新的手術(shù)方式治療惡性且致命的脊髓腫瘤。

New Breakthrough Treatment for Spinal Cancer Patients at Mount Sinai
05/16/07 -- The Mount Sinai Medical Center is the only hospital in New York City using the Novalis Shaped Beam Surgery System on spinal cancer. Novalis is the most advanced Stereotactic Radiosurgery(SRS) technology available to treat cancer tumors in the spine. Doctors at Mount Sinai are at the forefront of this medical breakthrough in neurosurgery and radiation oncology, using this technology to control deadly and complicated tumors from the spine for the first time ever.
"Hope is being given to patients with malignant and ultimately fatal spinal tumors where hope was never before available," said Dr. Isabelle Germano, Professor of Neurosurgery and Co-Director of The Radiosurgery Program at The Mount Sinai Medical Center. "All it takes is one thirty-minute out-patient treatment of pinpointed radiation and the tumor shrinks along with the pain from the cancer. Now cancer spreading to the spine doesn't mean a lifetime of pain or a wheelchair for a patient anymore."
Extremely precise, highly focused radiation is beamed directly into the spinal tumor, while sparing the normal surrounding tissue. Mount Sinai has had the Novalis Shaped Beam Surgery System technology since 2005. It is routinely used on the brain, head, neck, prostate and other tumors in the body with success. It is a friendly outpatient, non-invasive and non-surgical incisionless procedure. Patient risk is lowered, outcomes are improved, quality of life for patients enhanced, cancer pain eliminated, and the tumor is destroyed. Patients can continue to live a pain-free life and maintain complete mobility.
