Influence of Epidural Analgesia on Natural Killer Cell (NK) Activity After Colonic Cancer Surgery

December 22, 2014 updated by: Hillel Yaffe Medical Center
Regional anesthesia may decrease the release of endogenous opioids, increase Natural Killer cell (NK) function and decrease development of metastasis. The recent analysis of the Cancer Registry has noted an improved 5-year survival in patients who received epidural analgesia during surgery for colorectal carcinoma.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Count of live and dead target erythroleukemic cells
Time Frame: 72 hours
All clinical and laboratory parameters from blood samples taken before and after the operation will be compared between the two groups of patients. The nominal data comparison will be performed by ANOVA test, and the nonparametric data will be performed by Mann-Whitney test and interquartile ranges (IQR) for non-normally distributed data.
