 A recent analysis from the BC Cancer Agency suggested that patients treated with conventional EBRT within the Agency had inferior outcomes compared to PIPB. This data, as well as other indirect evidence, suggest that conventional EBRT may be a suboptimal treatment option compared to PIPB. Intensity modulated external beam radiotherapy IMRT is a new technology that allows for the delivery of high doses of radiation that tightly conforms to the target and limits the dose to surrounding critical structures. Although IMRT is currently a standard therapeutic option that is utilized in other cancer sites at the BC Cancer Agency, it has not been utilized in prostate cancer yet. Recent evidence has confirmed that this experimental therapy is able to allow for the safe escalation of dose for prostate cancer patients, which may lead to improved outcomes, without increasing toxicity. There is no current evidence that side effects and complication risks associated with IMRT are associated with any serious risk of increased toxicity, although this continues to be studied.
