Imaging Biomarkers for Precision Medicine in Locally Advanced Breast Cancer.

J Med Imaging Radiat Sci 2018 Dec 1;49(4):342-351. Epub 2018 Apr 1.

Department of Radiation Oncology, Sunnybrook Health Sciences Centre, Toronto, Canada; Physical Sciences, Sunnybrook Research Institute, Toronto, Canada.

Guidelines from the American National Comprehensive Cancer Network recommend neoadjuvant chemotherapy to patients with locally advanced breast cancer (LABC) to downstage tumours before surgery. However, only a small fraction (15%-17%) of LABC patients achieve pathological complete response (pCR); that is, no residual tumour in the breast, after treatment. Measuring tumour response during neoadjuvant chemotherapy can potentially help physicians adapt treatment, thus potentially improving the pCR rate. Read More

Internationalising Research Methods Teaching of Undergraduate Health Professionals.

J Med Imaging Radiat Sci 2018 Mar 2;49(1):97-105. Epub 2018 Jan 2.

School of Health Sciences, University of Liverpool, Liverpool, UK.

Objective: The project aims were: (1) identifying the pedagogical impact of collaborative student experience on student understanding of research methods and (2) evaluating the perceived value of providing students with an international perspective on their professional practice.

Methods: Student cohorts from year 1 of the University of Liverpool (UoL) (n = 80) and year 2 of the Royal Melbourne Institute of Technology University (RMIT) (n = 128) undergraduate Medical Radiation Science degree programmes participated in the intervention as part of their teaching. Students were tasked with designing, deploying, and analysing data from survey-based research projects and invited to provide feedback via an anonymous and voluntary online survey (UoL students) or an equivalent paper-based survey (RMIT students), comprising both quantitative (Likert) and qualitative (open) questions.

The Performance of Radiographic Criteria for Bone Malignancy When Applied to Computed Tomography and Magnetic Resonance Imaging.

J Med Imaging Radiat Sci 2018 Mar 26;49(1):84-89. Epub 2017 Nov 26.

Division of Pediatric Oncology, Department of Pediatrics, Kocaeli University School of Medicine, Kocaeli, Turkey.

Background: The conventional radiologic features that differentiate benign from malignant bone lesions were originally described using radiography (x-ray [XR]). When evaluating sectional imaging studies such as magnetic resonance imaging (MRI) and computed tomography (CT), one may apply these principles to identify malignant bone lesions. The aim of this study was to evaluate the performances of these radiographic features for detecting malignity when applied to CT and MRI. Read More

Assessing the Psychological Impact of Daily Bowel Preparation on Prostate Patients Who Receive Radiation Therapy.

J Med Imaging Radiat Sci 2018 Mar 4;49(1):70-75. Epub 2017 Oct 4.

Department of Radiation Therapy, Odette Cancer Centre, Sunnybrook Health Sciences Centre, Toronto, Ontario, Canada; Department of Radiation Oncology, University of Toronto, Toronto, Ontario, Canada. Electronic address:

Purpose: Evidence has shown that the prostate moves depending on filling of the rectum and, to a lesser extent, the bladder; many radiation therapy departments have adopted standardized bladder filling/rectal emptying protocols for radiotherapy treatment. Daily treatments may be delayed until appropriate volumes are attained; the resultant psychological impact of these delays on patients is unknown. The purpose of this study was to determine levels of anxiety, depression, distress, and bother related to bowel preparation for prostate cancer patients undergoing radiation therapy treatment.
