Abstract
BACKGROUND
We aimed to find out if there is a correlation between Doppler perfusion index (DPI) and platelet- derived endothelial cell growth factor (PD-ECGF), which is an angiogenic factor with angiopoietic function, in patients with colorectal carcinoma.
METHODS
50 colorectal carcinoma patients (22 cases with liver metastases, 28 cases without liver metastases) and 50 healthy controls were assessed with Doppler ultrasound as a preoperative evaluation. PD-ECGF expression in postoperative specimens of the 50 cases with colorectal carcinoma was assayed by immunohistochemistry and real-time polymerase chain reaction methods.
RESULTS
The mean DPI value was 0.29 ± 0.05 in patients suffering from colon cancer with hepatic metastases and 0.12 ± 0.03 in the healthy control group. The DPI value was significantly higher in patients with liver metastases (p < 0.05). PD-ECGF expression in patients with colorectal liver metastases was significantly higher than that in the group without liver metastases (p < 0.05). A positive correlation was found between DPI value and PD-ECGF expression in patients with liver metastases (p < 0.05).
CONCLUSIONS
DPI and PD-ECGF may be valuable factors when screening hepatic metastases in patients with colorectal cancer and serve as practical measurements in postoperative follow-up.
