生物谷报道：Mount Sinai综合癌症中心成为纽约唯一使用诺力刀（NOVALIS）手术系统治疗脊椎癌的医院。
NOVALIS是最先进的三维动态适形调强放射治疗系统，这是继常规放射线治疗后的最新一代放射治疗技术。它采用立体定位技术，对肿瘤组织进行精确的三维定位，采用计算机治疗计划设计系统精确设计最佳疗程，高能加速器产生能量可以调整的光子束和电子束，通过自动控制射线形状和调节射线强度分布，按照预先设计的治疗程序，以高精密度、大剂量、聚焦式照射肿瘤区域，使肿瘤周围的正常组织和器官减少放射线的照射，因此显著地提高肿瘤被照射的剂量，减少正常组织照射的剂量，可提高肿瘤控制率和患者生存率，减少放疗并发症，改善病人生存质量。
由于射线聚集的高剂量区形状与肿瘤形状一致，肿瘤周围的健康组织和器官的剂量迅速衰减，使肿瘤组织与健康组织间形成锐利的剂量梯度差异，因此可以达到无须开刀即可精确切除肿瘤的效果。
Mount Sinai综合癌症中心的医师Isabelle Germano表示，希望可以利用这种最新的手术方式治疗恶性且致命的脊髓肿瘤。

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.
