The aims of this study were to profile light radiated from two light-curing units (LCUs) and evaluate profile relationship to polymerization patterns within a resin-matrix composite (RMC). Beam profiles of one multiple emission peak light-emitting-diode and one quartz-tungsten-halogen curing-unit were measured using a beam profiler/spectrometer system. A camera-based profiler and an integrating sphere/spectrometer assembly were used to evaluate each LCU beam. Polymerization patterns within a nano-hybrid RMC were investigated using a mapping approach by assessing the degree of conversion utilizing micro-Raman spectroscopy and indirectly estimating cross-link-density by repeated microhardness testing before and after exposure to ethanol (%KH reduction, n = 3)...

Despite current risk stratification systems using traditional clinicopathologic factors, many localized and locally advanced prostate cancers fail radical treatment (ie, radical prostatectomy, radiation therapy with or without androgen deprivation therapy). Therefore, a pressing need exists for enhanced methods of disease stratification through novel prognostic and predictive tools that can reliably be applied in clinical practice. Exosomes are 50- to 150-nm small vesicles released by cancer cells that reflect the genetic and nongenetic materials of parent cancer cells...

PURPOSE: To provide evidence-based, resource-stratified global recommendations to clinicians and policymakers on the management and palliative care of women diagnosed with invasive cervical cancer. METHODS: ASCO convened a multidisciplinary, multinational panel of cancer control, medical and radiation oncology, health economic, obstetric and gynecologic, and palliative care experts to produce recommendations reflecting resource-tiered settings. A systematic review of literature from 1966 to 2015 failed to yield sufficiently strong quality evidence to support basic- and limited-resource setting recommendations; a formal consensus-based process was used to develop recommendations...

Non‑melanoma skin cancer (NMSC) is the most common form of cancer worldwide, comprising 95% of all cutaneous malignancies and approximately 40% of all cancers. In spite of intensive efforts aimed towards awareness campaigns and sun‑protective measures, epidemiological data indicate an increase in the incidence of NMSC. This category of skin cancers has many common environmental triggers. Arising primarily on sun‑exposed skin, it has been shown that ultraviolet radiation is, in the majority of cases, the main trigger involved in the pathogenesis of NMSC...

Radiosynoviorthesis is used for local treatment of recurrent joint effusions, leads to necrosis of inflamed synovium due to beta radiation energy served after intraarticular radionuclide administration. The aim of the therapy is destruction and fibrosis of abnormal, hypertrophic synovial membrane and then full recovery of its normal function after local corticosteroids and systemic modifying drugs failure. Radiosynoviorthesis is effective in different type of peripheral arthritis like rheumatoid arthritis, inflammatory spondyloarthtropaties, gout, chondrocalcinosis, pigmented villo-nodular synovitis, recurrent knee effusion after total joint replacement, idiopathic knee joint effusion, osteoarthritis and secondary prevention of intraarticular bleeding in haemophilia...

For situations with radioactive material out of control where it may be physically difficult or prohibited to access areas close to the source, measurements from distance may be the only way to assess the radiation environment. Using collimated detectors will provide means to locate the direction of the radiation from the source. To investigate the possibilities of mapping gamma emitting radioactive material in a closed non-enterable area, a tentative system for mapping radioactive materials from a distance was built...

A large stainless-steel collection tray (with a surface area of one square metre) was purpose built and mounted on the roof of the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) building at Yallambie, Victoria, Australia. Using this system two years' worth of wet/dry deposition samples have been collected and analysed. Smaller portable units were also developed for deployment in an emergency and/or for environmental monitoring. The cosmogenic radionuclide (7)Be and the naturally occurring terrestrial radionuclide (210)Pb have been used to validate the systems...

We conducted a comprehensive investigation of dislocations in Al0.46Ga0.54N. Using aberration-corrected scanning transmission electron microscopy and energy dispersive X-ray spectroscopy, the atomic structure and atom distribution at the dislocation core have been examined. We report that the core configuration of dislocations in AlGaN is consistent with that of other materials in the III-Nitride system. However we observed that the dissociation of mixed-type dislocations is impeded by alloying GaN with AlN, which is confirmed by our experimental observation of Ga and Al atom segregation in the tensile and compressive parts of the dislocations, respectively...

REVIEW
Paul H Sugarbaker
Malignant pleural mesothelioma is a disease characterized by persistent and progressive disease within the hemithorax. However, after aggressive local-regional treatment using surgery, regional chemotherapy, radiation therapy, and systemic chemotherapy, metastases outside of the pleural space may become the chief obstacle to long-term survival. One possible direction of cancer dissemination is direct extension through the hemidiaphragm into the peritoneal space by the disease itself or as a result of diaphragm resection...

The role of radiation therapy for pancreatic cancer is rapidly evolving in every stage of this disease. In resectable disease, there is conflicting evidence for adjuvant therapy, but an ongoing randomized cooperative group trial is attempting to define the role of adjuvant chemoradiation with modern systemic therapies and radiation techniques with an emphasis on radiation quality assurance. In borderline resectable pancreatic cancer (BRPC), there is an emerging body of literature demonstrating the success of neoadjuvant stereotactic body radiation therapy (SBRT) and a randomized cooperative group trial is actively accruing...

Patients with borderline resectable pancreatic adenocarcinoma have primary tumors within the pancreas that involve the mesenteric vasculature to a limited degree. Their tumors are nonetheless at high-risk for a microscopically positive surgical resection margin and/or early treatment failure when pancreatectomy is performed de novo. The optimal treatment strategy for these patients has not been established; however, relatively favorable outcomes can be achieved with systemic chemotherapy and radiation therapy (RT) prior to intended resection...

BACKGROUND/PURPOSE: The 21-gene recurrence score (RS) assay evaluates the likelihood of distant recurrence and benefit of chemotherapy in lymph node-negative, estrogen receptor (ER)-positive, HER2-negative breast cancer patients. The RS categories are associated with the risk of locoregional recurrence (LRR) in some, but not all studies. METHODS: We reviewed the institutional database to identify consecutive female patients with node-negative, ER+/HER2- breast carcinoma tested for the 21-gene RS assay and treated at our center from 2008 to 2013...

Metastasis to the breast from an extra-mammary malignancy has been documented in literature, however cervical cancer metastasis to the breast is very rare. Thirty-eight cases of metastatic deposit to the breast from cervical cancer have been reported in literature. Though most patients present with a breast lump, it is very difficult to clinically distinguish a primary breast malignancy from a metastatic deposit. Histopathology of the tissue, aided with immune-histochemical staining pattern provides a definitive diagnosis...

DISEASE OVERVIEW: POEMS syndrome is a paraneoplastic syndrome due to an underlying plasma cell neoplasm. The major criteria for the syndrome are polyradiculoneuropathy, clonal plasma cell disorder (PCD), sclerotic bone lesions, elevated vascular endothelial growth factor, and the presence of Castleman disease. Minor features include organomegaly, endocrinopathy, characteristic skin changes, papilledema, extravascular volume overload, and thrombocytosis. Diagnoses are often delayed because the syndrome is rare and can be mistaken for other neurologic disorders, most commonly chronic inflammatory demyelinating polyradiculoneuropathy...

We report on a 56-year-old Caucasian female, diagnosed with locally advanced, hormone-receptor-positive, and human epidermal growth factor receptor 2 (HER2)-positive cancer of the left breast. The patient received neoadjuvant chemotherapy with adriamycin/cyclophosphamide (AC) followed by docetaxel/trastuzumab. A partial clinical and radiographical response was documented after four cycles of AC. Approximately one week after the first cycle of docetaxel and trastuzumab, the patient presented with diffuse edema, erythema, and induration involving the entire left breast...

Pancreatic adenocarcinoma is the eighth leading cause of cancer deaths worldwide in men and ninth leading cause in women. Surgical resection offers the only chance of potential cure; however, only 9.4% of patients present at the localized, resectable stage, whereas the rest present at the locally advanced or metastatic, unresectable stages. Because of the guarded outcomes following systemic chemoradiation and the associated systemic toxicities, locoregional therapies have recently gained popularity. Various endoscopic techniques (endoscopic ultrasound [EUS]-guided ablative therapies, fine-needle instillation of antitumor agents, stereotactic body radiation therapy with EUS-guided fiducial marker placement, and EUS-guided brachytherapy) have been explored over the past several years...

Radiology procedure codes are a fundamental part of most radiology workflows, such as ordering, scheduling, billing, and image interpretation. Nonstandardized unstructured procedure codes have typically been used in radiology departments. Such codes may be sufficient for specific purposes, but they offer limited support for interoperability. As radiology workflows and the various forms of clinical data exchange have become more sophisticated, the need for more advanced interoperability with use of standardized structured codes has increased...
