Multiple Studies Presented at
ESTRO 36 Demonstrate System Improves Tumor Control with
Reduced Toxicities
Accuray Incorporated (NASDAQ: ARAY) announced today that studies
continue to demonstrate the unmatched flexibility of the
cutting-edge TomoTherapy® System to treat, with precision and
efficiency, a wide variety of indications of all complexities. More
than 50 studies were presented during poster and oral sessions at
the 36th Annual European Society for Radiotherapy &
Oncology (ESTRO) Meeting in Vienna,
Austria, May 5 - 9, 2017.

Study highlights include:
Breast
- A study evaluated hypofractionated intensity-modulated
radiation therapy (IMRT) using TomoHelical™ in 121 postmastectomy
patients with implant-based immediate breast reconstruction (IBR).
Results demonstrated the TomoTherapy Treatment Planning System
produced high-quality treatment plans providing optimal coverage of
both the chest wall and supraclavicular region and sparing of all
organs at risk. An additional analysis showed that the superior
dosimetric outcomes provided treatment benefits. The side effect
profile following treatment was favorable, with no patient
experiencing greater than grade 2 acute toxicity. Rates of toxicity
remained low in 85 patients with a median follow-up of 14.2 months.
Clinicians at the European Institute of Oncology in Milan, Italy, conducted these two
studies.
Lung
- A study of 68 patients with medically inoperable lung tumors
found that image-guided stereotactic body radiation therapy (SBRT)
delivered using TomoHelical provides an effective treatment option
with minimal toxicity. The study was conducted at three Italian
hospitals.
Prostate
- A retrospective study evaluated the safety and efficacy of
preoperative TomoHelical in combination with chemotherapy in
patients with locally advanced rectal cancer (LARC). The three-year
local control rate was 96.9% and treatment was well-tolerated.
Clinicians at two Swiss hospitals conducted the research, which
included the largest of this patient population to date.
- Toxicity and survival outcomes were reported for patients with
high-risk prostate cancer enrolled in a phase 1-2 study evaluating
hypofractionated TomoTherapy® and routine irradiation of pelvic
lymph nodes. Five- and seven-year biochemical relapse-free survival
(bRFS) was 87% and 80%, respectively; cancer-specific survival was
98% and 96%. Treatment was well-tolerated. Clinicians at the San
Raffaele Scientific Institute in Milano,
Italy conducted the study.
- Researchers at three European centers assessed the feasibility
of boosting radiation dose to the dominant intraprostatic lesion
(DIL) using the TomoTherapy System and found it to be a viable
treatment option. Additionally, based on a dosimetric comparison of
treatment plans, the system performed better than volumetric
modulated arc radiotherapy (VMAT) in terms of achievable boost
doses, target coverage and organ at risk sparing, and was similar
in several aspects to intensity-modulated proton therapy (IMPT).
"The data presented at the ESTRO 36 meeting continue to show
that the benefits of the TomoTherapy® System's ring gantry platform
and daily 3D image guidance in the treatment of a range of
clinical indications." said Fabienne Hirigoyenberry, VP Global
Medical and Scientific Affairs of Accuray. "The Radixact™ System,
the latest generation TomoTherapy platform, provides the same
unrivaled delivery capabilities while giving clinicians the
versatility to treat the broad spectrum of patients and disease
types with the highest level of precision and increased speed and
efficiency."
