Cervical cancer is the second most common cause of female cancer mortality worldwide. Concurrent chemoradiotherapy represents the standard of care for patients with stages IB2 to IVa cervical cancer. Unfortunately radiation therapy capacity is severely limited to non-existent in many Low and Middle-Income Countries. One solution has been to use chemotherapy to reduce tumor size to allow for radical surgery or in the case of inoperable cancers, as a placeholder until radiation is available. In Bangladesh, there has been the progressive development of resources for the treatment of women with gynecologic cancers...

PURPOSE: The anthropomorphic phantom program at the Houston branch of the Imaging and Radiation Oncology Core (IROC-Houston) is an end-to-end test that can be used to determine whether an institution can accurately model, calculate, and deliver an intensity modulated radiation therapy dose distribution. Currently, institutions that do not meet IROC-Houston's criteria have no specific information with which to identify and correct problems. In the present study, an independent recalculation system was developed to identify treatment planning system (TPS) calculation errors...

Metastatic epidural spinal cord compression (MESCC) is an oncologic emergency requiring prompt treatment to maximize neurologic function, ambulatory function and local control. Traditionally, options for MESCC included external beam radiation therapy with or without surgery. Surgery has usually been reserved for the patient with optimal performance status, single level MESCC or mechanical instability. Advances in external beam radiation therapy such as the development of stereotactic body radiation therapy have allowed for the delivery of high-dose radiation, allowing for both long-term pain and local control...

BACKGROUND: Children with malignant bone tumors have average 5-year survival rates of 60% to 70% with current multimodality therapy. Local control modalities aimed at preserving function greatly influence the quality of life of long-term survivors. In developing countries, the limited availability of multidisciplinary care and limited expertise in specialized surgery and pediatric radiation therapy, as well as financial cost, all form barriers to achieving optimal outcomes in this population...

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...

Hyperthermia (HT) is one of the hot topics that have been discussed over decades. However, it never made its way into primetime. The basic biological rationale of heat to enhance the effect of radiation, chemotherapeutic agents, and immunotherapy is evident. Preclinical work has confirmed this effect. HT may trigger changes in perfusion and oxygenation as well as inhibition of DNA repair mechanisms. Moreover, there is evidence for immune stimulation and the induction of systemic immune responses. Despite the increasing number of solid clinical studies, only few centers have included this adjuvant treatment into their repertoire...

Seungjong Oh, Siyong Kim
The number of imaging data sets has significantly increased during radiation treatment after introducing a diverse range of advanced techniques into the field of radiation oncology. As a consequence, there have been many studies proposing meaningful applications of imaging data set use. These applications commonly require a method to align the data sets at a reference. Deformable image registration (DIR) is a process which satisfies this requirement by locally registering image data sets into a reference image set...

The understanding of the relationship between genetic variation and an individual patient's response to radiation therapy (RT) has gained significant ground over the past several years. Genetic markers have been identified that could ultimately serve as the foundation for predictive models in clinical practice, and that hold the potential to revolutionize the delivery of precision medicine in oncology. Single nucleotide polymorphisms, single genes, and/or gene signatures could ultimately serve as the basis for patient stratification in prospective clinical trials...

Psychological stress exacerbates many pathological conditions including inflammatory skin conditions. The effect of psychological stress on acute radiation-induced skin reactions has not been documented before. Here, we aimed to explore if psychological stress could aggravate skin reaction severity in breast cancer patients. We conducted a secondary analysis of patient data obtained during a randomised, controlled clinical trial for acute radiation-induced skin reaction severity in 78 breast cancer patients...

Long-term care for head and neck cancer (HNC) survivors is complex and requires coordination among multiple providers. Clinical practice guidelines highlight the role of primary care providers (PCPs) in screening for secondary cancer/recurrence, assessment of late/long-term side effects, and referrals for appropriate specialty management of toxicity. However, these responsibilities may be difficult to meet within the scope of primary care practice. We conducted this study to explore preferences, comfort, and knowledge of PCPs in the care of HNC survivors...

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...

The best care for patients with cancer is most likely to be achieved when decisions about diagnosis, staging and treatment are made at multidisciplinary and multiprofessional meetings, preferably when all the professional expertise relevant to the patient's condition is gathered together. Questionnaires were sent to National Societies of Radiation Oncology and Medical Oncology concerning similarities and differences in training programs and multidisciplinary care in member states in Europe. Results indicated wide variation in training systems and practice...
