Multivariable Cox regression for OS.
| Covariate | Coefficient (Odds) | 95% CI | p |
|---|---|---|---|
| MTV/chromogranin A | 2.67 | 1.46–4.91 | 0.002 |
| γ-GT.log | 0.97 | 0.60–1.55 | 0.890 |
| LDH | 0.99 | 0.98–1.00 | 0.007 |
| Age | 1.15 | 1.08–1.23 | <0.001 |
| Gender | 0.75 | 0.28–1.99 | 0.560 |
| Grading | 1.26 | 0.46–3.47 | 0.653 |
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.
