Accuray wins FDA nod for iDMS data management system

Accuray (NSDQ:ARAY)  said today it won FDA 510(k) clearance for its iDMS data management system designed for sharing data between the company’s treatment delivery platforms. The Sunnyvale, Calif.-based company said the iDMS system is designed to integrate data from its technology platforms, including the Radixact, TomoTherapy and CyberKnife systems, as well as the company’s Accuray Precision treatment planning and oncology information systems. The iDMS allows users to store and manage all patient and treatment data across multiple devices to allow for more informed, efficient radiation treatments, Accuray said. “This most recent clearance reinforces Accuray’s commitment to providing clinicians with options for seamless, fully integrated treatment planning and data management, enhancing department workflow efficiency. The common database will make it possible for clinicians to use any available Accuray treatment system, expanding patient access to the precision and treatment versatility of our advanced radiation therapy systems,” chief commercial officer Lionel Hadjadjeba said in a press release. Earlier this month, Accuray released data from a prospective study comparing its TomoTherapy intensity-modulated radiation therapy system with Varian Medical‘s (NYSE:VAR), RapidArc radiotherapy system, touting a higher survival rate for patients treated with its TomoTherapy The post Accuray wins FDA nod for iDMS data management system...

The purpose of this study was to investigate the dosimetric impact of weight loss in head and neck (H&N) patients and examine the effectiveness of adaptive planning. Data was collected from 22 H&N cancer patients who experienced weight loss during their course of radiotherapy. The robustness of Intensity Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) treatment plans were compared including the potential need for replanning. The dosimetric impact of weight loss was evaluated by calculating a verification plan for each patient on an assessment CT scan taken during the course of treatment.

AbstractPurposeThe present work aims at evaluating intensity-modulated radiation therapy with simultaneous integrated boost (IMRT-SIB) in squamous cell carcinomas (SCC) of the larynx and hypopharynx.Methods/patientsWe performed a single institutional retrospective analysis on 116 pharyngo (29%)-laryngeal (71%) SCC patients (93% male) treated with IMRT-SIB to 66 –69.96 Gy in 33 fractions between 2008 and 2016. Those who underwent surgery (54%) received adjuvant radiation of 66 Gy at 2 Gy/fraction to the surgical bed. 16 patients (14%) were treated for a local recurrence after prior surgery. High-risk ly...

A 13-year-old female was diagnosed with a ponto- medullary brainstem glioma and following unsuccessful treatment with chemotherapy, underwent focal photon intensity modulated radiation therapy that resulted in a favorable response. Ten years later, the patient presented with acute onset left-sided hemiplegia and headaches. Magnetic resonance imaging (MRI) at presentation showed a large contrast- enhancing lesion with surrounding vasogenic edema and reduced diffusivity on diffusion- weighted imaging most concerning for a high grade secondary malignancy (Figure 1).

CONCLUSION: Including PLNs in radiation fields for high-risk or locally advanced prostate cancer is not associated with increased GI or GU toxicity at 3 years. Additional follow-up is required to answer questions about its impact on late GU toxicity. Results from ongoing trials will provide insight into the anticancer effectiveness of PLN irradiation.

Conclusions: Percutaneous CT fluoroscopy-guided permanent seed brachytherapy is a safe, efficacious, and cost effective primary and salvage treatment for lung cancer. CT-fluoroscopy resources are readily available in the community and are an effective alternative to stereotactic body radiation therapy (SBRT), intensity-modulated radiation therapy (IMRT)/proton beam, radiofrequency ablation (RFA), and cryoablation (CA). Percutaneous CT fluoroscopy-guided permanent seed brachytherapy has an equivalent or better local control rate, a lower resource cost, and a far lower integral radiation dose than other therapies. We believe...
