Univariable Cox regression for OS.

Variable	Coefficient (Odds)	95% CI	p
MTV/chromogranin A	2.67	1.60–4.43	<0.001
γ-GT.log	1.41	1.02–1.95	0.038
LDH	1.00	0.99–1.01	0.615
Age	1.13	1.07–1.20	<0.001
Gender	0.78	0.34–1.76	0.549
Grading	1.45	0.60–3.50	0.412

Both MTV and/chromogranin A can be considered to represent the tumor burden. MTV, molecular tumor volume; γ-GT, gamma-glutamyl transferase; LDH, lactate dehydrogenase. Correlation of clinical factors on overall survival. Bold values are statistically significant.
