ESTRO IMRT Course, May 2013
Prostate IMRT
“The risk of RISPC appears small, in the range of 1 in 220 to 1 in 290
over all durations of follow-up, based on older radiation techniques.
Importantly, the risk appears to increase with time, and beyond 5 years,
SPCs in the region of the original field may be considered RISPCs. To
date there are insufficient clinical data to draw firm conclusions about
the impact of more modern RT techniques, although limited evidence is
encouraging“
