Effects of Different Types of Perioperative Analgesia on Minimal Residual Disease Development After Colon Cancer Surgery
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Techniques of regional analgesia such as epidural analgesia may favorably influence metastasis development following cancer surgery compared to analgesia based on strong opioids such as morphine or piritramide. These beneficial effects, if present, are probably attributable to less immunosuppression of antimetastatic immune defenses.
The aim of this study is to identify techniques of perioperative analgesia with the potential to prevent metastasis development in patients undergoing open radical colon cancer surgery. In the early postoperative period, a relationship between metastasis development and the number of circulating cancer cells representing minimal residual disease has been shown. Therefore, effects of epidural, morphine-based and piritramide-based analgesia on the number of circulating cancer cells will be compared at several time points during the peroperative and early postoperative periods. The number of circulating cancer cells will be assessed in peripheral venous blood samples using real-time polymerase chain reaction. Perioperative care will be standardized and patients will be followed by clinical observation, laboratory analyses and monitoring instrumentation daily during their hospital stay.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from baseline number of circulating cancer cells at 3 weeks after surgery
Time Frame: Baseline prior to surgery, on day 2 postoperatively and three weeks after surgery
|
Number of circulating cancer cells will be measured in venous blood samples.
The quantitative real-time polymerase chain reaction using carcinoembryonic antigen and cytokeratine 20 as markers for circulating cancer cells will be used for minimal residual disease detection.
|
Baseline prior to surgery, on day 2 postoperatively and three weeks after surgery
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pain intensity assessment
Time Frame: 3 days postoperatively
|
Self reported pain intensity.
Scale: 0 = no pain, 10 = worst pain imaginable.
A score 0-10 will be recorded every four hours.
|
3 days postoperatively
