SBRT2015

Decision-making for SABR

Example: 8 mm spiculated lesion in the upper lobe in a 65

year old smoker without a history of malignancy

Algorithm

[Swensen SJ, 1997; Gould MK, 2007]:

34-40%

probability of malignancy

Even if lesion shows intense FDG uptake on a PET scan,

the

probability

of malignancy would still be only

79%

Recommendation: Follow-up imaging to establish growth
