IMRT 2018
Second Cancers: IMRT vs. 3-D
➢ Compared to the older 3-D conformal radiotherapy, modern IMRT techniques minimize the amount of normal tissue getting high doses
➢ But IMRT does result in larger volumes of normal tissue getting lower doses ( more fields and more leakage )
⚫ Which is preferable in terms of second cancers? ➢ Small volumes of normal tissue getting high doses (3D-CRT)?
➢ Larger volumes of normal tissue getting low doses (IMRT)?
