IORT is a targeted radiation therapy, delivered directly to the site where the tumour is resected during the surgery. The aim of IORT treatment is to deliver precise dose of radiation to the intended area for better treatment outcome, while minimising unnecessary damage to normal tissues. Multiple studies show clear evidence of how IORT is more effective in preventing future recurrences.
IORT utilises a miniaturised X-ray source to deliver a complete course of targeted radiation directly within the tumour cavity, where cancer cells are most likely to recur, meticulously destroying cancer cells while minimising the risk of damage to neighbouring healthy tissue.
IORT has been used to treat brain cancers such as Glioblastoma multiforme (GBM) and brain metastases. It is frequently used in conjunction with other treatments such as surgery, chemotherapy, and external beam radiation therapy.
