Influence of Opioid Analgesia on Circulating Tumor Cells in Laparoscopic Colorectal Cancer Surgery

Phase 4

Completed

• Conditions: Circulating Tumor Cell; Colorectal Cancer
• Interventions: Drug: Piritramid; Drug: Morphine

• Registration Number: NCT03700541
• Lead Sponsor: The Institute of Molecular and Translational Medicine, Czech Republic

Brief Summary

Arm && Interventions

Group	Intervention	Description
Piritramid	Piritramid	Piritramid-based perioperative analgesia
Morphine	Morphine	Morphine-based perioperative analgesia

Primary Outcome Measures

Name	Time	Method
Change in number of circulating tumor cells prior to surgery to 2 - 4 weeks after surgery	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.

Secondary Outcome Measures

Name	Time	Method
Pain assessment	Time Frame: 3 days postoperatively	Pain intensity assessed using Numerical Rating Scale (0-10)
