Analysis of SUVs as Predictors of TTP

	Univariate analysis		Multivariate analysis
Variable	Hazard ratio	P	Hazard ratio	P	Regression coefficient
SUV_max	0.95 (0.908–0.996)	0.04	0.96 (0.91–1.01)	NS	−0.04
ΔSUV_max	0.54 (0.19–1.49)	NS
ΔSUV_T/S	0.22 (0.07–0.65)	0.006	0.29 (0.10–0.90)	0.03	−1.24
Number of PRRT cycles	0.59 (0.22–1.60)	NS

NS = not statistically significant.
Data in parentheses are 95% confidence intervals. SUV_max is for most prominent tumor before PRRT. ΔSUV_max and ΔSUV_T/S are for responder vs. nonresponder.
