The aim of this review is to present the available radiobiological, technical and clinical data about extreme hypofractionation in primary prostate cancer radiotherapy. The interest in this technique is based on the favourable radiobiological characteristics of prostate cancer and supported by advantageous logistic aspects deriving from short overall treatment time. The clinical validity of short-term treatment schedule is proven by a body of non-randomised studies, using both isocentric (LINAC-based) or non-isocentric (CyberKnife(®)-based) stereotactic body irradiation techniques...

Patients with cancer can present with difficult management issues, as the medicine can sometimes cause sequelae destructive to healthy tissue. As this population lives longer, cardiotoxic effects are beginning to emerge, but the early recognition of this signal can prove difficult, with too late a recognition leading to lifelong cardiac impairment and dysfunction. Cardio-oncology can bridge this difficulty, and echocardiography and its newer imaging abilities are proving efficacious in this population. This article will address common sequelae of cardiotoxic treatment regimens and offer recommendations for echocardiographic surveillance...

Virtually all cases of invasive cervical cancer are associated with infection by high-risk strains of human papilloma virus. Effective primary and secondary prevention programs, as well as effective treatment for early-stage invasive cancer have dramatically reduced the burden of cervical cancer in high-income countries; 85% of the mortality from cervical cancer now occurs in low- and middle-income countries. This article provides an overview of challenges to cervical cancer care in sub-Saharan Africa (SSA) and identifies areas for programmatic development to meet the global development goal to reduce cancer-related mortality...

BACKGROUND: Shortening the duration of radiation therapy would benefit women with early breast cancer treated with breast conserving surgery. It may also improve access to radiation therapy by improving efficiency in radiation oncology departments globally. This can only happen if the shorter treatment is as effective and safe as conventional radiation therapy. This is an update of a Cochrane Review first published in 2008 and updated in 2009. OBJECTIVES: To assess the effect of altered radiation fraction size for women with early breast cancer who have had breast conserving surgery...

PURPOSE: The purpose of this work was to develop, validate, and compare a highly computer-aided method for the segmentation of hot lesions in head and neck 18F-FDG PET scans. METHODS: A semiautomated segmentation method was developed, which transforms the segmentation problem into a graph-based optimization problem. For this purpose, a graph structure around a user-provided approximate lesion centerpoint is constructed and a suitable cost function is derived based on local image statistics...

OBJECTIVE: Although radiation therapy (RT) and concurrent chemoradiotherapy (CCRT) are the global standards for adjuvant therapy treatment in cervical cancer, many Japanese institutions choose chemotherapy (CT) because of the low frequency of irreversible adverse events. In this study, we aimed to clarify the trends of adjuvant therapy for intermediate/high-risk cervical cancer after radical surgery in Japan. METHODS: A questionnaire survey was conducted by the Japanese Gynecologic Oncology Group to 186 authorized institutions active in the treatment of gynecologic cancer...

PURPOSE: Use of hypofractionation is increasing in radiation oncology because of several factors. The effects of increasing hypofractionation use on departments and staff currently based on fee-for-service models are not well studied. METHODS: We modeled the effects of moving to hypofractionation for prostate, breast, and lung cancer and palliative treatments in a typical-sized hospital-based radiation oncology department. Year 2015 relative value unit (RVU) data were used to determine changes in reimbursement...

PURPOSE: Taste and smell changes (TSCs) are common in head and neck (H&N) cancer and during and after chemotherapy (CT) and radiotherapy (RT). It is an area that has been under-investigated, particularly in the treatment-naive, but can negatively impact nutritional status. This study examined the prevalence, severity and characteristics of TSCs in people with non-H&N solid tumours, before CT and RT, and their relationship with co-occurring symptoms. METHODS: A prospective, observational study was conducted...

UNLABELLED: Accelerated partial breast irradiation via brachytherapy (APBI-b) is offered as an alternative to whole breast irradiation (WBI) for selected patients with breast cancer. This study evaluates our clinical experience with APBI-b to identify the reasons for decreased clinical utilization in recent years. We performed an analysis of the prospective database of breast cancer patients treated with APBI-b between 2004 and 2013. During that time, 245 patients received APBI-b, most having stage I (77%) or stage 0 (20%) breast cancer...

A paradigm shift from current population based medicine to personalized and participative medicine is underway. This transition is being supported by the development of clinical decision support systems based on prediction models of treatment outcome. In radiation oncology, these models 'learn' using advanced and innovative information technologies (ideally in a distributed fashion - please watch the animation: from all available/appropriate medical data (clinical, treatment, imaging, biological/genetic, etc...
