The Tammy Walker Cancer Center has a new tool in its cancer-fighting arsenal giving north central Kansans the confidence in knowing they have access to the latest technology right here in Salina.

The new Trilogy system with BrainLab stereotactic technology is a more technologically advanced and more precise way to verify tumor position and treat it more effectively. It's called Stereotactic Radiotherapy (SRT) – a non-invasive surgery and treatment option.

"I am ecstatic about having the Trilogy in Salina because it encompasses the capabilities of the Cyberknife and the Gamma Knife with the flexibility that is necessary for cancer patients who have areas at risk that cannot be addressed by the other conventional machines," says Claudia Perez-Tamayo, M.D., radiation oncologist at the Tammy Walker Cancer Center.

Trilogy guides the delivery of very precise forms and amounts of radiation therapy. It brings precision targeting to very, very small spaces that before were difficult to treat. Knowing exactly where the tumor is located (which can shift between treatments) makes it less difficult to target.

Because Trilogy targets only the tumor, patients are benefitted by irradiating less of the surrounding normal tissue, making it possible to deliver higher concentrations of radiation directly and more precisely on the tumor.

"With stereotactic brain and body radiosurgery, we can treat patients with early and more advanced cancer allowing for a quicker recovery, low morbidity and cure," says Dr. Claudia Perez-Tamayo.

Tammy Walker Cancer Center's Trilogy also features state-of-the-art motion management capability, which compensates for the natural breathing motion of the patient, thereby increasing treatment accuracy, patient comfort, and reducing patient stress.

How It Works
When patients are positioned on a treatment table, an X-ray system mounted on a robotic arm is rotated around the body, to gather images that pinpoint a tumor's exact location. These images are then compared with existing images in order to determine if the tumor has moved since the last treatment. Because tissues and organs can settle around bones differently each time a patient lies down on a treatment table, tumors can end up in different positions from one treatment session to another. In addition, tumors can move several centimeters due to a patient's normal respiratory cycle.

In some cases, only one treatment session is needed. Other cases may require a few treatment sessions. The actual delivery of the radiation beam is brief; however, preparation time may take a few hours. Most patients go home immediately after the procedure.

"By bringing the Trilogy to Salina, we have brought one of the most powerful tools in the world allowing the local and regional areas of central Kansas accessibility to the most comprehensive radiotherapeutic cancer treatments, said Dr. Perez-Tamayo. "This addition to the Salina Regional Health Center oncology service line completes the circle of exceptional oncologic care. The da Vinci robotic surgery system, the Midwest Cancer Alliance for medical oncology advancement, and the Trilogy as the third prong allows the scope of treatments here in Salina to be at the level of top cancer centers in the country.
