D-dimer levels greater than 8000\u2005ng FEU\/ml and age over 60\u2005years were independent poor prognostic factors for overall survival (p&lt;0.001.).

This suggests that elevated D-dimer levels in patients with VTE and malignancy are not solely due to presence of thrombus. High D-dimer levels in malignancy are likely to reflect the biology of the underlying tumour, with higher levels observed in breast, prostate and bowel cancers.<\/jats:p>\n
