Clinical considerations affecting choice of radiotherapy technique for periocular malignancies.
| Favored radiation techniques | Eyelid lesion | Superficial lesion | Deep lesion (>2.5 cm) | PNI | Nodal regions |
|---|---|---|---|---|---|
| Electrons with eye shield | Yes, preferred | Yes | – | – | – |
| IMRT | Possibly with acrylic shield | Yes | Yes | Yes | Yes |
| IMPT | – | Yes | Yes | Yes | Yes |
| 3DCRT | – | – | – | – | – |
IMRT, intensity modulated radiation therapy; IMPT, intensity modulated proton therapy; 3DCRT, 3-dimensional conformal radiotherapy; PNI, perineural invasion.
