MedicalResearch.com: What is the background for this study? What type of single dose radiation is used?
Response: The new paper published in the
British Journal of Cancer (
go.nature.com/3yN0mzu) expands on the previously published results of the large international randomised trial (TARGIT-A trial)
(BMJ 2020;370:m2836), that confirmed the long-term effectiveness of Targeted Intraoperative Radiotherapy (TARGIT-IORT): a breast cancer treatment which is increasingly available throughout the world.
The TARGIT-A trial found that a single dose of targeted radiotherapy during surgery (TARGIT-IORT) is just as effective as conventional radiotherapy, which requires several visits to hospital after surgery. From the perspective of patients, it is so much better for them and also allows prompt completion of cancer treatment during the COVID pandemic.
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 up 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.
The new results are described on the Nature.com and UCL webpages
