Depending on the institution, CT examination doses can vary dramatically by a factor of ten, said Professor John Damilakis, PhD, associate professor at the University of Crete, Iraklion, ahead of the session. The difference is related principally to variations in the examination technique, as the protocol or the imaging system itself determines the level of radiation.
Tumour cells can migrate, sometimes also during a surgery to remove the tumour. US researchers recently found, that perioperative treatment with a drug known as colchicine might protect against recurrences at the site of the surgical wound.
By Rudolf Schwarz and Andreas Krüll, of the Section of Radiation Oncology Department, Ambulanzzentrum GmbH of the University Medical Center Hamburg-Eppendorf
For individualised radiotherapy, high-precision delineation and characterisation of the tumour is critical. If highest radiation doses are delivered in a targeted fashion, the chance of tumour cell kill increases and tumour control probability is enhanced.
