Known as the "Stablemates Trial," the randomized study will test the hypothesis that the 3-year overall survival in high risk operable patients with stage I NSCLC is equivalent or greater in patients who undergo stereotactic ablative radiotherapy (SAbR) as compared with conventional sublobar resection (SR) surgery. Led by co-chairs Hiran Fernando, MD, Boston Medical Center, and Robert Timmerman, MD, University of Texas Southwestern Medical Center, the study currently involves 34 institutions and 258 patients.

"In addition to a potentially longer survival rate, SAbR may benefit some lung cancer patients by offering them a noninvasive, outpatient treatment option that is easier to tolerate and that doesn't interfere greatly with their normal, everyday living activities," said Dr. Timmerman.

Sponsored by the Joint Lung Cancer Trialist's Coalition, the study is being administered by the Department of Radiation Oncology at the University of Texas Southwestern Medical Center. Over the next five years, the study will examine patients' overall, disease-free, and regional recurrence-free survival rates three years after treatment, as well as adverse events and post-treatment quality of life measures.

"Varian believes in supporting high quality clinical research," said Kolleen Kennedy, president of Varian's Oncology Systems business.  "This clinical trial presents the opportunity to advance radiation oncology and enhance the standard of patient care by giving clinicians a noninvasive treatment option in determining the appropriate therapy for patients."
