A number of original publications and review articles have addressed the issue of perioperative immune modulation and cancer outcome. The objective of this module is to review current understanding surrounding the pathways involved and the evidence implicating commonly used anesthetic agents. ⋯ Recommendations for a specific anesthetic technique based on cancer outcome alone cannot be made. A pragmatic solution would be to offer regional anesthesia in isolation or combined with propofol infusion to cancer patients if appropriate and if local expertise is available. Regional anesthesia offers excellent analgesia, a low incidence of postoperative nausea and vomiting, and a favourable immunological profile based on current understanding of laboratory evidence.

The current methods (work based assessments and logbooks) used to assess procedural competency and performance have well-documented deficiencies. Cumulative sum analysis (cusum), a statistical method that generates performance graphs over time, is an alternative tool that is not currently widely used. The purpose of this review is to investigate its current role in anesthetic procedural skills training and performance. ⋯ Cusum can be used to assess procedural competency, but several problems need to be overcome before it can become a universally accepted method. It is ideally placed to be used as a quality control tool for a trained individual and could also be used to assess the impact of new training methods or equipment on performance.
