Serum vascular endothelial growth factor (VEGF) levels correlate with micrometastases. (A) The number of micrometastases by zone correlates with serum VEGF levels for each mouse. (B) Zone 1 micrometastases (micromets) did not correlate with peak serum VEGF levels (R²=0.0016). (C) Zone 2 micrometastases correlated with peak serum VEGF levels (R²=0.41528). (D) Zone 3 micrometastases correlated with peak serum VEGF levels (R²=0.3272). (E) Total micrometastases correlated with peak serum VEGF levels (R²=0.1969). Pearson correlation coefficient and R² analysis are indicated in the text and figure, respectively; p<0.05.
