Heena J Mavani, Jeannette Y Wick
: In 2016, the American health care system was faced with more than 1.6 million new cases of cancer, and individuals older than 65 years of age will be affected disproportionately. Many older individuals are poor candidates for traditional treatments (e.g., chemotherapy, radiation) because of actual or potential treatment-related adverse events. Researchers continuously look for novel therapeutic strategies, and an exciting new one is on the horizon: virotherapy. Viruses' ability to infect and kill human cells makes them promising cancer treatments...

PURPOSE: To determine if data mining of an electronic whiteboard improves the management of the Time to Treatment Initiation (TTI) in radiation oncology. METHODS: An electronic whiteboard designed to help in managing the planning workflow and improves communication regarding patient planning progress was used to record the dates at which each phase of the planning process began or completed. These are CT Sim date, Plan Start, Physician Review, Physicist Review, Approval for Treatment Delivery, Setup or Verification of Simulation...

: The desperate need for radiotherapy in low and mid-income countries (LMICs) has been well documented. Roughly 60 % of the worldwide incidence of cancer occurs in these resource-limited settings and the international community alongside governmental and non-profit agencies have begun publishing reports and seeking help from qualified volunteers. However, the focus of several reports has been on how dire the situation is and the magnitude of the problem, leaving most to feel overwhelmed and unsure as to how to help and why to get involved...

J Van Dyk, A Meghzifene
PURPOSE: The last few years have seen a significant growth of interest in the global radiation therapy crisis. Various organizations are quantifying the need and providing aid in support of addressing the shortfall existing in many low-to-middle income countries (LMICs). The Lancet Oncology Commission report (Lancet Oncol. Sep;16(10):1153-86, 2015) projects a need of 22,000 new medical physicists in LMICs by 2035 if there is to be equal access globally. With the tremendous demand for new facilities, equipment and personnel, it is very important to recognize quality and safety considerations and to address them directly...

PURPOSE: Webinars have become an evolving tool with greater or lesser success in reaching health care providers (HCPs). This study seeks to assess best practices and metrics for success in webinar deployment for optimal global reach. METHODS: Webinars have been developed and launched to reach practicing health care providers in the field of radiation oncology and radiosurgery. One such webinar was launched in early February 2016. "Multiple Brain Metastases & Volumetric Modulated Arc Radiosurgery: Refining the Single-Isocenter Technique to Benefit Surgeons and Patients" presented by Drs...

PURPOSE: The global burden of cancer is considerable, particularly in low and middle-income countries. Massachusetts General Hospital (MGH) and Botswana-Harvard AIDS Institute have partnered with the oncology community and government of Botswana to form BOTSOGO (BOTSwana Oncology Global Outreach) to address the rising burden of cancer in Botswana. Currently, radiation therapy (RT) is only available at a single linear accelerator (LINAC) in Gaborone Private Hospital (GPH). BOTSOGO worked to limit the absence of RT during a LINAC upgrade and ensure a safe transition to modern radiotherapy techniques...

PURPOSE: The ASTRO document "Safety is no accident: A FRAMEWORK FOR QUALITY RADIATION ONCOLOGY AND CARE" recommends external reviews of specialized modalities. The purpose of this presentation is to describe the implementation of such a program for Stereotactic Radiosurgery (SRS) and Stereotactic Body radiation Therapy (SBRT). METHODS: The margin of error for SRS and SBRT delivery is significantly smaller than that of conventional radiotherapy and therefore requires special attention and diligence...

PURPOSE: To develop a method for remote dosimetric auditing the delivery of VMAT using EPID which allows for simple, inexpensive and time efficient dosimetric credentialing for clinical trials. METHODS: Remote centers are provided with CT datasets and planning guidelines to produce VMAT plans for a head and neck and a post-prostatectomy treatment. Plans are transferred in the planning system to two virtual water equivalent phantoms, one flat and one cylindrical...

PURPOSE: To monitor the evolution of radiation-induced cardiac inflammation in a canine model using hybrid positron emission tomography (PET/magnetic resonance imaging (MRI). METHODS: Research ethics approval was obtained for a longitudinal imaging study of 5 canines after cardiac irradiation. Animals were imaged at baseline, 3 months, 6 months, and 12 months post cardiac irradiation using a hybrid PET-MRI system (Biograph mMR, Siemens Healthcare). The imaging protocol was designed to assess changes in cardiac inflammation using (18) F-fluorodeoxyglucose ((18) F-FDG) PET tracer...

AIM: To compare quality of life (QOL) between standard (SFX) chemoradiotherapy (arm A) and altered fractionation radiotherapy (AFX) with panitumumab (PMab; arm B). METHODS: Patients with T any N + M0 or T3-4N0M0 squamous cell head-neck carcinoma were randomised to SFX (70 Gy/35/7 wks) plus cisplatin (100 mg/m(2) IV × 3) versus AFX (70 Gy/35/6 wks) plus PMab (9 mg/kg IV × 3). QOL was collected at baseline, end of radiation therapy (RT) and 2, 4, 6, 12, 24 and 36 months post-RT using the Functional Assessment of Cancer Therapy Head and Neck (FACT-H&N), MD Anderson Dysphagia Index (MDADI) and SWAL-QOL...

Over the last 60 years, the International Atomic Energy Agency (IAEA) has been working to introduce, expand and improve radiotherapy services, working with partners such as the World Health Organization (WHO) to improve cancer diagnosis, treatment, care and control through collective action in low- and middle-income countries (LMICs). The Lancet Oncology Commission on radiotherapy published a report that defined five calls for action to expand global access to radiotherapy, drawing on the previous work of the Global Taskforce on Radiotherapy for Cancer Control...

Closing the gap in cancer care within low- and middle-income countries and in indigenous and geographically isolated populations in high-income countries requires investment and innovation. This is particularly true for radiotherapy, for which the global disparity is one of the largest in healthcare today. New models and paradigms and non-traditional collaborations have been proposed to improve global equity in cancer control. We describe recent initiatives from within the radiation oncology community to increase access to treatment, build the low- and middle-income countries' radiation oncology workforce, mobilise more professionals from within high-income countries and raise awareness of the global need for equitable cancer care...

PURPOSE: To analyze the most recent results of the Imaging and Radiation Oncology Core Houston Quality Assurance Center's (IROC-H) anthropomorphic head and neck (H&N) phantom to determine the nature of failing irradiations and the feasibility of altering credentialing criteria. METHODS: IROC-H's H&N phantom, used for intensity-modulated radiation therapy credentialing for National Cancer Institute-sponsored clinical trials, requires that an institution's treatment plan agrees within ±7% of measured thermoluminescent dosimeter (TLD) doses; it also requires that ≥85% of pixels pass ±4 mm distance to agreement (7%/4 mm gamma analysis for film)...
