SUNNYVALE, California, December 20, 2016 /PRNewswire/ --
Practice-Changing Study Presented at the 2016 Best of ASTRO Meeting
Accuray Incorporated (NASDAQ: ARAY) announced today new data showing that 80 percent of patients with solitary plasmacytoma of the bone (SPB) had excellent cancer control four years after receiving intensity-modulated radiation therapy (IMRT) delivered with the TomoTherapy® System, in addition to immunomodulatory drugs (IMiDs) or proteasome inhibitors (PI).[1] The concurrent treatments were well-tolerated and toxicity was manageable with standard approaches.[1] The study was presented on November 11, 2016 at the 2016 Best of ASTRO meeting, a two-day summary of the ASTRO Annual Meeting, at which the most relevant and practice-changing abstracts are presented.

"For patients newly diagnosed with SPB, this study could change the game. We now have hope that the patients with SBP can live without disease and without major side effects after treatment with new targeted agents in addition to precise radiation treatments," said Youlia M. Kirova, MD, senior radiation oncologist at the Curie Institute in Paris and investigator of the study. "Tolerance was excellent because of the TomoTherapy System's highly conformal dose distribution which enabled clinicians to deliver optimal doses of radiation while sparing healthy tissue and also because of the less toxic new targeted treatments."
"This is a new approach enabling radiation oncologists, medical oncologists, and hematologists to give their patients prolonged progression-free survival (PFS)," Fabienne Hirigoyenberry-Lanson, PhD, vice president medical affairs, at Accuray. "These study results add to the evidence supporting the TomoTherapy System as an innovative and safe radiation therapy treatment for hemopathies such as hematological cancers.[1],[2]"
SPB is a rare disease with a high rate of progression to multiple myeloma (MM). The role of systemic treatments given concurrently with radiation therapy was uncertain in SPB and had never been evaluated
This study is the first to investigate whether patients who received a short course of IMiD or PI in addition to IMRT delivered with the TomoTherapy System had a longer progression free survival than patients treated only with IMRT. The study showed that:
About the Study
The study titled "Intensity Modulated Radiation Therapy by Tomotherapy (IMRT) Concurrent With a Short Systemic Treatment for Solitary Plasmacytoma of the Bone (SPB) With Improvement of Progression-Free Survival" (1) is a retrospective analysis of the medical and dosimetry records of 28 consecutive patients treated for SPB in the Department of Radiation Oncology at the Curie Institute between 2004 and 2013. All patients had histologically proven plasmacytoma of the bone, without bone marrow involvement. Fifteen patients received the standard treatment, 40 Gy radiotherapy, and 13 patients received treatment with IMiDs or PIs, in addition to the 40 Gy radiotherapy delivered by IMRT.
