Author Interviews, BMJ, Breast Cancer, Cancer Research, Radiation Therapy / 10.11.2020 Interview with: Professor Jayant S Vaidya MBBS MS DNB FRCS PhD Professor of Surgery and Oncology University College London What is the background for this study? What type of single dose radiation is used? Response: The findings of the large international randomised trial (TARGIT-A trial), published in the British Medical Journal (BMJ 2020;370:m2836), confirm the long-term effectiveness of Targeted Intraoperative Radiotherapy (TARGIT-IORT): a breast cancer treatment which is increasingly available throughout the world. For most women with early breast cancer, a single dose of targeted radiotherapy during surgery is just as effective as conventional radiotherapy, which requires several visits to hospital after surgery. Conventional external beam radiotherapy (EBRT) is delivered from outside the body via a radiotherapy machine (linear accelerator), and consists of a daily treatment session (known as fractions) to the whole breast, over a period between three to six weeks. Each of these treatments is given over a few minutes, but requires 15 to 30 hospital visits, which could be a significant distance from where the patient lives. TARGIT-IORT is delivered immediately after lumpectomy (tumour removal), via a small ball-shaped device placed inside the breast, directly where the cancer had been. The single-dose treatment lasts for around 20 to 30 minutes and replaces the need for extra hospital visits, benefiting both patient safety and well-being. The device used is called INTRABEAM. More details are described on the BMJ and UCL webpages: (more…)
Author Interviews, OBGYNE, Science / 05.12.2018 Interview with: "38 week fetus" by Zappys Technology Solutions is licensed under CC BY 2.0 Kimberley Whitehead Neuroscience, Physiology & Pharmacology University College London What is the background for this study? Response: Fetuses move a lot! Very similar movement patterns are seen in both pre-term and full-term newborn infants, but their function is unclear. In animals such as rats, spontaneous movement and consequent feedback from the environment during the early developmental period trigger specific patterns of electrical activity in the brain that are necessary for proper brain mapping.
