Identifying factors which contribute to accurate seed placement in LDR prostate brachytherapy

The accurate placement of radioactive Iodine-125 seeds in the treatment of prostate cancer is not only critical to patient survival but also critical in reducing side effects. Incorrect placement of seeds can result in under-dosing or over-dosing areas of the prostate and/or over-dosing organs at risk (OAR). The results of the post implant dosimetry as well as the patient's biochemical relapse free survival (BRFS) are dependent on the brachytherapy teams’ skills in both treatment planning and accurate seed placement. This presentation will identify some of the techniques and procedures used to ensure accurate seed placement during LDR prostate brachytherapy.

William Keough

Edinburgh Cancer Centre
Physicist Head of Brachytherapy

Will graduated with a Ph.D. in Medical Physics from the UCLA School of Medicine and he has practiced in both the United States and the United Kingdom.

Will has been involved in LDR prostate brachytherapy since 1981. He is currently head of brachytherapy at the Edinburgh Cancer Centre. The centre performs approximately 100 LDR prostate implants per year. As Director of Medical Physics at Renown Regional Medical Centre in Reno, Nevada, WilI was responsible for all special procedures including LDR and HDR Brachytherapy. Additionally, Will has experience in tomotherapy and Novalis IMRT / IGRT, stereotactic radiosurgery, SABR, treatment planning and dosimetry. Will’s current teaching responsibilities include lecturing in brachytherapy to oncology registrars, medical physicists, and clinical technologists. He also instructs clinical scientists from the UK and Ireland in real-time LDR Brachytherapy treatment planning and implant procedures.
