Elevated Angiogenic Factor Levels After Transarterial Radioembolization for Colorectal Cancer Liver Metastases May Predict a Poor Prognosis.

Although the finding was not statistically significant, some of the baseline levels of circulating angiogenic factors were higher in patients with extrahepatic disease; this difference in baseline VEGF and bFGF levels was nearly significant. A small number of patients included in our analysis might account for the low significance; therefore, a larger patient population may improve the significance of these differences.
