TomoTherapy® Treatment Plan for Scalp Carcinoma
This clinical case study demonstrates the TomoTherapy® Hi·Art® system's ability to treat a large, irregular lesion on the scalp in lieu of electron therapy.The Plan
Figure 1: TCS views of TomoTherapy treatment plan for scalp carcinoma.
Figure 1 shows the TCS views for treating a large, irregularly-shaped superficial lesion of the scalp. The TomoTherapy Hi·Art treatment system® can deliver conformal doses to superficial targets better than conventional electron therapy.
The Goals
- Tumor: 60 Gy
- Minimal dose to brain, optic nerves and lenses
The Results
The DVH in Figure 2 demonstrates how the TomoTherapy Hi·Art system is able to deliver a highly-conformal dose of 60 Gy to the target area, while limiting dose to both ocular orbits to less than 7 Gy each, and limiting dose to both lenses to less than 2 Gy each.
