PURPOSE: To identify factors associated with a near-miss or safety incident (NMSI) in patients undergoing radiotherapy and identify common root causes of NMSIs and their relationship with incident severity. METHODS: We retrospectively studied NMSIs filed between October 2014 and April 2016. We extracted patient-, treatment-, and disease-specific data from patients with an NMSI (n = 200; incident group) and a similar group of control patients (n = 200) matched in time, without an NMSI...

Intensity-modulated radiotherapy (IMRT) is not widely used in developing countries due to technical challenges and a lack of expertise and resources. We outline head and neck cancer IMRT implementation challenges and highlight how improvised solutions allowed successful IMRT transition in Jordan. This article showcases a 'peer-assisted learning' model, promoting IMRT transition in other developing countries. Unlike the 'top-down' approach, this model is uncommonly addressed in oncology journals. Developing countries could benefit from this article to enhance the adoption of modern radiotherapy technology...

Evidence of cancer cells that bear attributes analogous to those of normal stem cells has developed a hierarchical model of cancer's architecture and progression. This subset of cancer stem cells (CSCs) drives the progression and therapy resistance of cancers. Research to identify the phenotypes of these CSCs presents evidence of a subpopulation that is more resistant to therapy and may proliferate in response. Literature shows that CSCs typically represent around 1%-10% of cell populations in head and neck cancer but this proportion may increase in response to a therapeutic radiation dose...

PURPOSE: The Imaging and Radiation Oncology Core Houston (IROC-H) (formerly the Radiological Physics Center) has reported varying levels of agreement in their anthropomorphic phantom audits. There is reason to believe one source of error in this observed disagreement is the accuracy of the dose calculation algorithms and heterogeneity corrections used. To audit this component of the radiotherapy treatment process an independent dose calculation tool is needed. METHODS: Monte Carlo multiple source models for Elekta 6MV and 10MV therapeutic x-ray beams were commissioned based on measurement of central axis depth dose data for a 10 x 10 cm(2) field size and dose profiles for a 40 x 40 cm(2) field size...

Adenoid cystic carcinoma of the head and neck area is a rare malignant tumor with acceptable short-term but mediocre long-term prognosis. Radical tumor excision with clear resection margins, and sometimes resection of the facial nerve due to perineural growth, remains the fundamental therapy. We present 3 distinct clinical cases and discuss the current therapeutic options with special focus on plastic-reconstructive techniques. For reconstruction, the full armament of local and free flaps, as well as prosthetics, may be necessary...

INTRODUCTION: Patients with head and neck cancer (HNC) submitted to radiotherapy alone or combined chemoradiotherapy present a high prevalence of malnutrition at baseline. Prophylactic use of gastrostomy has been suggested for these patients for delivering enteral nutrition. On the other hand, other authors have failed to demonstrate the effectiveness of this measure over nasogastric tube feeding. MATERIAL AND METHODS: We studied 40 patients with HNC with moderate or severe malnutrition who were offered either prophylactic percutaneous gastrostomy before starting oncologic treatment or close follow-up with nutritional counseling with the placement of a nasogastric tube when necessary...

BACKGROUND: A high rate of glycolysis leading to elevated lactate content has been linked to poor clinical outcomes in patients with head and neck and cervical cancer treated with radiotherapy. Although the biological explanation for this relationship between lactate and treatment response remains unclear, there is a continued interest in evaluating strategies of targeting metabolism to enhance the effectiveness of radiotherapy. The goal of this study was to investigate the effect of metabolic-targeting through HIF-1α inhibition and the associated changes in glycolysis, oxygen consumption and response on the efficacy of high-dose single-fraction radiotherapy (HD-SFRT)...
