3D Printing Enhances the Effectiveness of Radiotherapy

Researchers have used 3D printing to produce replica models of organs and tumours of patients to help compute precisely how much radiation has been delivered to the cancer.

Preliminary studies show the models can accurately reproduce the contour of a patient’s tumour and the surrounding organs – and could mimic the precise location of the tumour within the patient’s body.

Initial tests at The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Trust discovered the models enabled the dose of radiation a patient has received to be calculated more precisely – permitting following doses to be corrected appropriately.

Researchers were planning to improve molecular radiotherapy – in which doctors give a patient a radioactive drug designed to target a tumour, and aim for a dose high enough to kill cancer cells but not too high that healthy tissue is damaged by it.
