What cumulative dose constraints to you utilize when treating high risk prostate cancer with combined external beam and brachytherapy boost?
Do you utilize EQD2 rectal and bladder constraints?
Answer from: Radiation Oncologist at Community Practice
With EBRT and LDR we don’t use any specific constraints . we avoid any hot spot at bladder neck and limit prescribed dose to rectum to less than 1 cc . We now routinely use space OAR for boost so rectal dose is usually not a concern.
