Advantages and disadvantages of SIB boost

 Advantages:

 Limits overall treatment time of nodal target (hypo-fractionation of small volumes)  Limits irradiation of normal tissue as compared to AP-PA post boost

 Is robust to inter-fraction motion

 Disadvantages:

 In case of large lymph nodes, the boost volume becomes higher – can be modified through replanning after e.g. 20-25Gy
