Clinical Trial Summary

Surgical resection is one of the most important treatments for solid organ cancer. Whereas cancer recurrence and/or metastasis are the major reasons of treatment failure. The outcomes after surgery are mainly dependent on the balance between the immune function of the body and the invasiveness of residual cancer. Preclinical and retrospective studies suggest that anaesthetic techniques and drugs may affect the long-term outcomes in patients undergoing cancer surgery. The investigators hypothesize that epidural anesthesia-analgesia may improve long-term survival in the elderly who undergo major surgery for cancer.

Description:

Surgical resection is the main treatment for potentially curable solid organ cancer. However, long-term survival after cancer surgery is far from satisfactory. Quite a number of patients develop tumor metastasis and/or recurrence after surgery, which are associated with poor long-term outcomes. The development of tumor recurrence and/or metastasis after surgery is mostly dependent on the balance between the anti-tumor immune function of the body and the ability of implantation, proliferation and neovascularization of the residual cancer cells.

Studies showed that anaesthetic techniques and drugs may influence the cellular immune function and long-term outcomes. For example, it was found that ketamine and thiopental, but not propofol, suppresses natural killer (NK) cell activity; all three drugs caused a significant reduction in NK cell number; isoflurane and halothane inhibit interferon stimulation of NK cell cytotoxicity; nitrous oxide interferes with deoxyribonucleic acid, purine, and thymidylate synthesis and depresses neutrophil chemotaxis; opioids have been shown to suppress cell-mediated and humoral immunity.

Considering the potential harmful effects of general anesthesia/anesthetics, there is increasing interest on the effect of regional anaesthesia. Retrospective studies investigating the relationship between epidural anesthesia and outcomes after cancer surgery provide different results. In a meta-analysis of retrospective studies, regional anesthesia was associated with improved survival, but had no effect on the occurrence of cancer recurrence/metastasis. The investigators hypothesize that epidural anesthesia may produce favorable effects on long-term survival in the elderly who undergo major surgery for cancer under general anesthesia. However, there are no sufficient evidences in this aspect.
