Upon publication of this paper in 2009, the authors noticed two errors – one in the abstract and one within the Results section.

On page 1444 (Abstract), the seventh sentence should read as follows:

‘In a combining analysis, patients with a CXCR7high/CXCR4high tumour had a significantly shorter DFS and OS than patients with a CXCR4low/CXCR7low tumour’.

On page 1447 (Results), the first sentence of the section entitled ‘CXCR4 and CXCR7 coexpression and patients outcome’ should read as follows:

‘Interestingly, patients with CXCR4low/CXCR7low tumour expression have a significantly prolonged DFS and OS than those patients with a CXCR4high/CXCR7high tumour expression (Figure 3C; median DFS: 15.80 months (95% CI: 10.43–21.17) vs 7.62 (2.97–12.27), P=0.037; median OS: not reached vs 9.69 (95% CI: 5.13–14.07), P=0.001)’.
