Table 1. Changes in CECs in paired blood specimens obtained before and after nephrectomy in 20 patients with non-metastatic sporadic RCC.
| CEC factor | Median difference (range) from ‘before nephrectomy’ value | P a |
|---|---|---|
| CEP count (cells μl−1) | 0.02 (−0.06 to 1.2) | 0.05 |
| mCEC count (cells μl−1) | −0.08 (−52.56 to 32) | 0.75 |
| CEP:mCEC ratio | 0.001 (−0.05 to 0.037) | 0.20 |
Abbreviations: CECs=circulating endothelial cells; RCC=renal cell carcinoma; CEP=circulating endothelial progenitor; mCEC=mature CEC.
