PURPOSE: The goal of the work described here was to determine whether deep inspiration breath-hold (DIBH) produces a clinically meaningful reduction in pulmonary dose compared with free breathing (FB) during locoregional radiation for right-sided breast cancer. METHODS AND MATERIALS: Four-field, modified-wide tangent plans with full nodal coverage were developed for 30 consecutive patients on paired DIBH and FB CT scans. Nodes were contoured according to European Society for Radiotherapy and Oncology guidelines...

PURPOSE: Incident learning systems encompass volumes, varieties, values, and velocities of underlying data elements consistent with the V's of big data. Veracity, the 5th V however exists only if there is high inter-rater reliability (IRR) within the data elements. The purpose of this work was to assess IRR in the nationally deployed RO-ILS: Radiation Oncology-Incident Learning System (R) sponsored by the American Society for Radiation Oncology (ASTRO) and the American Association of Physicists in Medicine (AAPM)...

: 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...

: Research papers authored by Medical Physicists address a large spectrum of oncologic, imaging, or basic research problems; exploit a wide range of physical and engineering methodologies; and often describe the efforts of a multidisciplinary research team. Given dozens of competing journals accepting medical physics articles, it may not be clear to an individual author which journal is the best venue for disseminating their work to the scientific community. Relevant factors usually include the Journal's audience and scientific impact, but also such factors as perceived acceptance rate, interest in their topic, and quality of service...

PURPOSE: To initiate a discussion on the current and evolving role of Medical Physicists based on author's professional and research experience in patient safety and quality control. METHODS: Several professionals of the departments of Medical Physics and Radiation Oncology, chiefly devoted to clinical tasks, began a research program on patient safety and quality control in a framework provided by the implementation of intraoperative radiotherapy (IORT). We performed studies on virtual simulation for IORT, in vivo dosimetry, failure mode and effect analysis (FMEA), statistical process control (SPC), and receiver operating characteristics of dosimetric equipment...

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 describe the results of IROC Houston's international and domestic end-to-end QA phantom irradiations. METHODS: IROC Houston has anthropomorphic lung, liver, head and neck, prostate, SRS and spine phantoms that are used for credentialing and quality assurance purposes. The phantoms include structures that closely mimic targets and organs at risk and are made from tissue equivalent materials: high impact polystyrene, solid water, cork and acrylic. Motion tables are used to mimic breathing motion for some lung and liver phantoms...

PURPOSE: The purpose of this educational program is to motivate talented, intelligent individuals to become stakeholders in the global effort to improve access to radiotherapy. METHODS: The need to improve global access to radiotherapy has been clearly established and several organizations are making substantial progress in securing funding and developing plans to achieve this worthwhile goal. The incorporation of elective international rotations in residency programs may provide one possible mechanism to promote and support this future investment...

PURPOSE: To use confocal microscopy to distinguish cells in different phases of the cell cycle before and after treatment with pegylated gold nanoshells (PEG-AuNSs). METHODS: Transfected fibrosarcoma cells (HT1080-EYFP-53BP1-FUCCI) were cultured in T-25 flasks and seeded in glass bottom dishes. These cells express the fluorescent probe AmCyan during the G2/S phases of the cell cycle, mCherry during the G1 phase, and EYFP tagged to the DNA repair protein 53BP1. After allowing cells 4 h to adhere to dishes, PEG-AuNS (Nanospectra Biosciences, Houston, TX) at a concentration of 0...

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...

Radiation therapy is a common component of curative cancer treatment. However, there is a significant incidence of treatment failure. In these cases salvage surgical options are sometimes appropriate. Accurate assessment of response and early recognition of treatment success or failure is therefore critical to guide treatment decisions and impacts on survival and the morbidity of treatment. Traditionally, treatment response has depended upon anatomical measurement of disease. However, this may not correlate well with the presence of disease, especially after radiotherapy...

BACKGROUND: A wide variety of systemic diseases and internal malignancies have cutaneous manifestations. In the context of internal malignancy, many cutaneous changes are highly specific to the underlying malignancy, while other changes are nonspecific. Some changes are also due to the modalities employed in the treatment of malignancies. METHODS: Two hundred and fifty patients who were diagnosed with internal malignancy and who were attending the department of radiation oncology, were evaluated at the Department of Dermatology, Sexually Transmitted Diseases and Leprosy of Government Medical College, Srinagar...
