In initial tumor specimens, GDF-15 expression was rare and predominantly confined to tumor cells. tGDF-15 correlated with high cGDF-15 levels at baseline [median 1.8 ng/ml (1.13-2.34 ng/ml) in positive tumor specimens, versus 0.76 ng/ml (0.55-1.17 ng/ml) in negative tumor specimens; <em>P</em> = 0.0087].
