Treatment Planning for Lung Cancer
Download Presentations

Have you joined the frenetic, unstoppable race to introduce new technologies at all costs? Does your institution place the improvement of its own image and financial gains before the patient’s best interest? Could this be a reason for the spiralling costs of medical care? Are we rushing ahead without going through the necessary intermediate steps when it comes to introducing new techniques?

The case of lung cancer could be exemplary:

• Sophisticated technology is used including PET/CT imaging for target volume delineation, IMRT and respiratory gating for optimal target coverage and organs at risk sparing
• But an increase in normal tissue toxicity is reported, maybe not only due to the use of concomitant chemo-radiotherapy
• Question: what dose calculation method is being used?

During the seminar recent clinical results of thoracic radiotherapy will be reviewed by Suresh Senan, Professor of Clinical Experimental Radiotherapy at the VU University Medical Center in Amsterdam. See the list of references he has recommended. Professor René-Olivier Mirimanoff will address the important topic of volume delineation. And we have enlisted Anders Ahnesjö, Professor at the University of Uppsala, to present the current concepts in dose calculations. In order to better address this issue, he has suggested that, prior to the meeting, a state of today’s practice in Switzerland be established and justified.
So, with the soon to be released official invitation and programme of the seminar, you will receive a brief questionnaire about the planning and delivery of lung cancer treatments in your institution.
The seminar will close with a 60 minutes round table discussion during which a set of joint recommendations could be drafted.
