Abstract PURPOSE: Radiation-induced oral mucositis is one of the main side effects during and after the treatment of head and neck cancer patients. The study was designed to provide evidence on the effectiveness of thyme honey on oral mucositis management. METHODS: This was a randomised controlled trial (RCT) with 72 head and neck cancer patients who were divided either to the intervention group (thyme honey rinses) or to the control group (saline rinses). Oral mucositis was assessed according to the Radiation Therapy Oncology Group (RTOC criteria), and assessments were performed weekly starting at the 4th we...

ConclusionFor SBRT treatments in DIBH, a non-uniform dose prescription in the PTV, combined with a non-coplanar VMAT arc arrangement, significantly spares the ipsilateral lung while increasing dose to the GTV without major treatment time increase.

Background: Immediate prosthetic breast reconstruction produces a satisfactory aesthetic result with high levels of patient satisfaction. However, with the broader indication for postmastectomy adjuvant radiation therapy, many patients are advised against immediate breast reconstruction because of concerns of implant loss and infection, particularly as most patients also require chemotherapy. This retrospective cohort study examines outcomes for patients who underwent immediate two-stage prosthetic breast reconstruction after mastectomy with or without adjuvant chemotherapy or radiotherapy. Methods: Between 1998 and 2...

Conclusions: The authors describe a novel small-animal model for irradiated, implant-based breast reconstruction where histologic analysis shows structural changes in the skin consistent with known effects of radiation therapy and expansion in human skin. This model represents a significant improvement from previous ones and, as such, holds the potential to be used to test new therapeutic agents to improve clinical outcomes.

Authors: Spencer S Abstract For more than a decade, the incidence of head and neck cancers has been increasing in the United States. Worldwide, they are the ninth most common cancer. Today, newer advances in radiotherapy (RT), such as fractionation, 4-dimensional cone-beam CT, and intensity-modulated RT, have provided clinicians with the opportunity for improved patient outcomes. At the NCCN 23rd Annual Conference, Sharon Spencer, MD, described the advantages of advances in RT and the means to mitigate untoward side effects. PMID: 29784752 [PubMed - in process]

Publication date: October 2018 Source:Radiation Physics and Chemistry, Volume 151 Author(s): Abdullah Abuhaimed, Colin J. Martin For multi-detector CT scans, the region of the body irradiated is determined from the scan projection radiograph and is adjusted for each patient. However, for cone beam CT scans, standard field sizes are often used without any adjustment for patient size. Moreover, when cone beam CT is used with image guided radiation therapy, the scan position varies with each patient, based on the tumour position and clinical requirements. The aim of this study is to quantify the influence of the position of ...
