Table II.
Calculated rectal wall NTCPs for the planned and total delivered doses. A negative NTCP change means the NTCP calculated from the total delivered dose is less than that for the planned dose. NTCP Changes larger than +/−5% are shown in Bold. Changes of V30, V50, V70 and V75 between planned DVH and total delivered DVH are also shown. VD changes larger than +/− 10% are shown in Bold.
