Background: Retrospective evidence suggests that valproic acid (VPA), an antiepileptic drug, is associated with improved outcomes in glioblastoma. The exact mechanism of interaction of VPA with radiation and temozolomide (TMZ) is still unclear. Laboratory studies show that VPA can enhance tumor cell kill while at the same time protect the normal neural tissue. The aim of this study was to prospectively evaluate the benefit of VPA on outcomes in glioblastoma. Materials and Methods: In this single-arm prospective study, patients of glioblastoma were started on seizure prophylaxis with VPA (15-20 mg/kg/day) following maximal safe resection...

PURPOSE: Oncology providers are leaders in patient safety. Despite their efforts, oncology-related medical errors still occur, sometimes resulting in patient injury or death. The Veterans Health Administration (VHA) National Center of Patient Safety used data obtained from root cause analysis (RCA) to determine how and why these adverse events occurred in the VHA, and how to prevent future reoccurrence. This study details the types of oncology adverse events reported in VHA hospitals and their root causes and suggests actions for prevention and improvement...

Although stereotactic radiosurgery (SRS) is an effective modality in the treatment of brainstem metastases (BSM), radiation induced toxicity remains a critical concern. To better understand how severe or life-threatening toxicity is affected by the location of lesions treated in the brainstem, a review of all available studies reporting SRS treatment for BSM was performed. Twenty-nine retrospective studies investigating SRS to BSM were reviewed. The rates of grade 3 or greater toxicity, based on the Common Terminology Criteria for Adverse Events varied from 0-9...

Eggert Stockfleth, Mike Bastian
Actinic keratosis (AK) is a common skin condition that results from exposure to chronic ultraviolet (UV) radiation. AK is characterized by visible, scaly lesions; sub-clinical lesions may also be present within a field of UV-exposed skin. These lesions exist on a disease continuum with squamous cell carcinoma. Field therapies, such as ingenol mebutate, aim to treat the visible and sub-clinical lesions within an area of sun-damaged skin. Areas covered: According to the SmPC, ingenol mebutate has a proposed dual mechanism of action that induces cell death necrosis with the production of a local pro-inflammatory response and stimulation of apoptosis...

Radionuclide synovectomy (RSV) is a form of minimally invasive treatment of persistent joint inflammation. The procedure has a high safety profile and the occurrence of serious adverse events, such as full-thickness skin radiation necrosis, is rare. Less severe radiation events, while more common, are usually benign and self-limiting. We present two cases of low-grade beta burns that developed after RSV, despite proper injection technique. The potential long-term risk of such exposure is also discussed, with reference to historical radiation incidents...

Life expectancy of patients treated for brain tumors has lengthened due to the therapeutic improvements. Cognitive impairment has been described following brain radiotherapy, but the mechanisms leading to this adverse event remain mostly unknown. Technical evolutions aim at enhancing the therapeutic ratio. Sparing of the healthy tissues has been improved using various approaches; however, few dose constraints have been established regarding brain structures associated with cognitive functions. The aims of this literature review are to report the main brain areas involved in cognitive adverse effects induced by radiotherapy as described in literature, to better understand brain radiosensitivity and to describe potential future improvements...
