Influence of Opioid Analgesia on Circulating Tumor Cells in Open Colorectal Cancer Surgery (POACC-1)

Influence of Peri-operative Opioid Analgesia on Circulating Tumor Cells in Patients Undergoing Open Colorectal Cancer Surgery - Multi-center, Randomized Clinical Trial

To compare the effects of three types of perioperative analgesia on the number of circulating tumor cells following radical colorectal cancer surgery. To find correlations with other perioperative factors and clinical/pathological disease characteristics.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in number of circulating tumor cells prior to surgery to 2 - 4 weeks after surgery
Time Frame: 1 - 3 days before surgery to 4 weeks after surgery
Baseline number of circulating tumor cells will be recorded prior to surgery in a venous blood sample. Number of circulating tumor cells will be measured 2 - 4 weeks after surgery in a venous blood sample. These two values will be compared.
1 - 3 days before surgery to 4 weeks after surgery
