Planning and implementing an implanted fiducial programme for prostate cancer radiation therapy.
Using implanted gold seeds as fiducial markers to verify the position of the prostate in radiation therapy is well accepted and is becoming the standard of practice and requirement for international multicentre trials. In 2006 the decision was made at the Peter MacCallum Caner Centre (Peter Mac) to plan for and implement this process as standard clinical practice for radical dose prostate treatments (74-78 Gy). Before this, programme verification of field placement for prostate cancer radiation treatment was routinely carried out using regular off-line electronic portal imaging with matching of bony anatomy. A small multidisciplinary team investigated and assisted in the implementation of this new practice across the Peter Mac sites at East Melbourne and our three satellite centres. Issues considered included seed size, number and position in the prostate, implant equipment, imaging equipment and procedure and consent and information forms. The use of a custom made fiducial pack, comprehensive patient information and a daily on-line imaging process was implemented. The experience of the first 28 patients at Peter Mac from January 2007 to May 2007 inclusive is reported on.
