Stereotactic radiosurgery

With the 2009 acquisition of six new Elekta treatment machines, 30 stations networked to the MOSAIQ® Oncology Information System (OIS) and 19 treatment planning systems, the Instituto do Cancer do Estado de Sao Paulo (ICESP) is reinforcing its role as the largest cancer center for adult patients in Latin America. ICESP opened in May 2008, and began radiation therapy treatments in June 2010. By December 2010, it had commissioned four of the five Elekta Synergy® systems it purchased and is scheduled to bring an Elekta Axesse® system for stereotactic treatments—Latin America’s first—on line by February 2011.

Among the most common sites for cancers to metastasize is the brain. According to the American Cancer Society, 20-40 percent of all cancer patients develop metastatic tumors in the brain. This is the single most common type of intracranial tumor. In the U.S. alone, around 150,000 people are diagnosed with brain metastases each year. The incidence continues to increase as advances are made in the treatment of systemic cancer. The most common primary sources of brain metastases are lung (17%), renal cell (10.5%), and breast (5.2%) cancer and melanoma (8%). Read the rest of this entry »
Gamma Knife® surgery sometimes referred to as stereotactic radiosurgery (SRS), is a non-invasive method for treating brain disorders. It is the delivery of a single, high dose of irradiation to a small and critically located intra-cranial volume through the intact skull. It is preferred for its extreme accuracy, efficiency and outstanding therapeutic response. Read the rest of this entry »

Elekta and Karolinska University Hospital (Stockholm, Sweden) recently signed a letter of intent to launch a joint research project that will evaluate and improve the efficacy of stereotactic radiation therapy for cancer patients. This unique, three-year, multi-product collaboration will entail the clinical implementation and expansion of Elekta clinical solutions at Karolinska. Read the rest of this entry »
SBRT

SBRT

SRS technology has evolved significantly since it was first introduced in the 1950s to treat small brain tumors. The application of SRS to treat tumors in other regions of the body, known as Stereotactic Body Radiation Therapy (SBRT), is becoming much more common as evidence grows regarding the effectiveness of SBRT in treating select lung, spine and liver tumors.

Elekta supports the application of SBRT in several ways. First, from a technology perspective, Elekta provides motion management features, imaging capabilities and workflow designed specifically for SBRT treatments. These technological advancements will be on display at the Elekta booth in San Diego during ASTRO 2010.

Another way that Elekta supports the application of SBRT is by sponsoring research consortia to help gather additional clinical evidence regarding the efficacy of SBRT treatments across a variety of pathologies.

One of these groups, the Elekta Lung Research Group (ELRG), consists of physicians and physicists worldwide who are actively collaborating to evaluate outcomes in early stage inoperable non-small cell lung cancer patients. These researchers have already gathered data for more than 400 patients treated with volumetric image-guided stereotactic lung radiotherapy using daily online VolumeView™. The clinical findings of this group are summarized in a whitepaper, titled “SBRT Lung Treatment” by Dr. Joel Goldwein.

By sponsoring groups like the ELRG, Elekta continues to stay on the cutting edge of research into SBRT in order to develop innovative technology to improve opportunities for successful treatment with SBRT.

Just as Gamma Knife® SRS evolved into a precise, effective method to treat intracranial targets, radiotherapy systems equipped with advanced immobilization and target localization technology have matured to play a frontline role in extracranial SRS. Few examples of this are as striking as the experience of UPMC (Pittsburgh, Pa.), where clinicians have had remarkable success using their Elekta Synergy® S to treat spine and paraspinal lesions. Physicians have found spine SRS to be a safe procedure, providing durable pain relief and high local control. In addition, patients tolerate single fraction SRS well and avoid the risk and prolonged recuperation associated with open surgical resection. Read the rest of this entry »
