Conclusion

 Combination of parametrial boost and BT:

 High EBRT and BT gradients in the same region



Difficult to predict target dose



Difficult to predict OAR dose

 Large normal tissue volume irradiated to a significant dose  Combination of interstitial BT and intracavitary BT:

 Higher target dose (compared with para-boost)  Reduced OAR dose (compared with para-boost)  Better conformality with HR-CTV and IR-CTV

 Simultaneous integrated boost



Limits overall treatment time
