Comparative Analysis of Local Control Prediction Using Different Biophysical Models for Non-Small Cell Lung Cancer Patients Undergoing Stereotactic Body Radiotherapy

Table 3

Difference of the 3-year LC data predicted using the Gucken, Santiago, and Tai models.

FS	Group			Group
	Median			Median
	(Range)			(Range)
	Gucken	Santiago (%)	Tai (%)	Gucken	Santiago (%)	Tai (%)
	NA	−0.2; (−0.2~0.2)	10.7; (10.7~11.9)	NA	−1.1; (−1.3~−1.0)	7.4; (6.8~8.1)

The Gucken model was taken as a benchmark in all data. FS = fraction scheme. = the maximum dose was 120% of the prescribed dose. = the maximum dose was 110% of the prescribed dose.  Gy = 30 Gy in 1 fraction and other fraction schemes had similar definition. NA = not available; the Tai model for predicting 3-year LC; statistically significant with value < 0.05 compared with the Gucken model.
