Technical requirements:
-
Use adequate imaging modality for delineation (e.g. liver MRI)
-
Motion management
-
Consider fiducials (e.g. liver)
-
Planning:
-
Dose calculation algorithm: type B is advised (especially in lung tumors)
-
Prescription to isodoseline
-
Inhomogeneity – steep dose gradients
-
Pretreatment imaging and verification is mandatory
-
QA (see AAPM reports)
Clinical indications:
Cranial: RCT
Extracanial: no randomized controlled trials
Most data on lungs:
•
Excellent LC similar to surgery
•
Low toxicity rate (cave: central tumours)
standard of care for inoperable T1-T2a lung tumors
Other sites: good LC, low toxicity, often small studies
promising
