Radiotherapy Planning

Standard dose radiotherapy is 20Gy in 5 fractions delivered Monday- Friday over 1 week. The dose-escalated radiotherapy arm is 36Gy in 6 fractions over 2 weeks (Mon/Wed/Fri). Doses to organs at risk should be minimised by using intensity modulated radiotherapy (IMRT) for planning where possible, although in centres where IMRT is not available, 3D conformal radiotherapy can be used. In cases where there are concerns about doses to organs at risk, the final fraction can be missed, treating to 30Gy in 5 fractions. The radiotherapy protocol can be downloaded by clicking here.
