PURPOSE: Stereotactic body radiation therapy (SBRT) is increasingly being used for the management of localized prostate cancer. This trend combined with declining use of brachytherapy (BT) has pushed issues and questions regarding the use of SBRT to the forefront. A systematic literature review was conducted to review the current evidence of biochemical disease-free survival (bDFS) and toxicity of SBRT in high-risk (HR) prostate cancer. METHODS AND MATERIALS: A search was carried out on the PubMed and Embase databases...

Surgical resection, when feasible, is the standard of care for hepatocellular carcinoma (HCC). However, many tumors are not resectable at the time of diagnosis. Recently, stereotactic body radiation therapy (SBRT) has emerged as a non-invasive local therapy for both non-resectable primary hepatic malignancies as well as hepatic metastases. Knowledge of the expected hepatic parenchymal appearance post treatment, as well as potential pitfalls and complications, is essential for accurate evaluation of treatment response...

Stereotactic body radiotherapy (SBRT) for lung tumours has been gaining wide acceptance in lung cancer. Here, we review the technological evolution of SBRT delivery in lung cancer, from the first treatments using the stereotactic body frame in the 1990's to modern developments in image guidance and motion management. Finally, we discuss the impact of current technological approaches on the requirements for quality assurance as well as future technological developments.

Stereotactic body radiation therapy (SBRT) has become a standard treatment for non-operable patients with early stage non-small cell lung cancer (NSCLC). In this context, medical physics community has largely helped in the starting and the growth of this technique. In fact, SBRT requires the convergence of many different features for delivering large doses in few fractions to small moving target in an heterogeneous medium. The special issue of last month, was focused on the different physics challenges in lung SBRT...

The role of external beam radiation therapy (EBRT) in the management of upper gastrointestinal malignancies is constantly evolving. As radiation therapy techniques improve and are able to deliver more ablative doses of radiotherapy while sparing healthy tissue, radiation can be applied to a wider range of clinical scenarios. Stereotactic body radiation therapy (SBRT) allows a high dose of radiation to be delivered to a highly conformal treatment volume in a short amount of time. Another potential advantage of SBRT is its ability to increase tumor immunogenicity, while also having less of an immunosuppressive effect on the patient, as compared to conventionally fractionated radiation therapy...

Background: Parenchymal changes after stereotactic body radiation therapy (SBRT) make differential diagnosis between treatment outcomes and disease recurrence often difficult. The purpose of our study was to identify the radiographic features detectable at computed tomography (CT) scan [high-risk features (HRFs)] that allow enough specificity and sensitivity for early detection of recurrence. Methods: We retrospectively evaluated patients who underwent SBRT for inoperable early stage non-small cell lung cancer (NSCLC)...

Background: Orthotopic liver transplantation (OLT) is the most effective treatment for hepatocellular carcinoma (HCC) in patients with underlying cirrhosis and portal hypertension. Availability of OLT is limited by donor-organ shortages, which increase patient waiting time until OLT. A variety of bridging therapies (BT) have been used to halt tumor progression in patients on the OLT waiting list. Despite complete radiologic responses following BT, viable tumor is often present in explants...

Background: Increasing evidence indicates a relationship between systemic inflammation and survival following treatment in various tumors. However, the correlation of systematic inflammation with survival after stereotactic ablative radiotherapy (SABR) in early stage non-small cell lung cancer (NSCLC) has not been well established. Patients and methods: We retrospectively analyzed patients with newly diagnosed early stage NSCLC treated with SABR in a single institution from 2011 to 2015. The neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and lymphocyte- monocyte ratio (LMR) were calculated as systemic inflammation biomarkers...
