extended
abstract
M. Coffey (Dublin):
Introduction to Radiobiology and Novel Radiotherapy Technologies
V. Gregoire (Brussels):
The Clinical Use of PET-CT in Radiotherapy Planning Head and Neck Cancer
N. Patel (London):
Physics and Technical Aspects of PET-CT Scanning for Radiotherapy Planning


Educational objectives:

  1. To understand the basic principles of radiobiology and tumour volumes including dose response curves, side effects, GTV/CTV/PTV
  2. To understand the different types of conformal radiotherapy modalities currently available including intensity-modulated radiation therapy (IMRT), volumetric-modulated arc therapy (VMAT), image-guided radiotherapy (IGRT) and stereotactic radiotherapy (SRT)
  3. To describe the clinical role of PET-CT in radiotherapy planning
  4. To describe the technical aspects of PET-CT acquisitions for radiotherapy planning including positioning, flat bed, immobilisation devices etc
  5. To understand the principles of respiratory motion correction in PET-CT for radiotherapy planning and its effects in the treatment of lung and liver cancers


Summary:

This session has been jointly organised by EANM and ESTRO (the European Society for Radiotherapy and Oncology). In 2012, an estimated 14.1 million new cases of cancer were diagnosed worldwide and 8.2 million deaths were attributed to it. By 2030 this is predicted to rise to 13 million cancer deaths. Whilst cancer rates have increased, so has the ability of radiotherapy professionals to treat cancer effectively. Radiotherapy is most frequently given as an adjuvant to surgery, chemotherapy and targeted therapies. Targeted treatments are now commonly applied in such a way that radiation doses to cancer cells give improved local tumour control and therapeutic outcome, whilst sparing critical organs & healthy tissue and minimising unwanted radiation side effects. The combination of PET & CT data from hybrid imaging allows radiotherapists better insight not only into the physical size and distribution of tumours but also their metabolic activity. The first talk will outline some basic principles of cell biology; side effects and the volumes used in radiotherapy delivery and then describe some of the most common radiotherapy techniques currently used worldwide. The second talk will focus on clinically relevant examples of how PET-CT imaging assists radiation therapists and planning dosimetrists with a specific focus on head & neck cancers. Finally, the third talk will describe best practices in PET-CT acquisitions for radiotherapy planning and some of the latest advances in respiratory motion management including breath-holding, 4DCT and 4DPET.
