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)?
