General design: Presentation of a new type of a study protocol for evaluation of the effectiveness of an immune modifier (rhG-CSF, filgrastim): prevention of postoperative infectious complications and of sub-optimal recovery from operation in patients with colorectal cancer and increased preoperative risk (ASA 3 and 4). A randomised, placebo controlled, double-blinded, single-centre study is performed at an University Hospital (n = 40 patients for each group). This part presents the course of the individual patient and a complication algorithm for the management of anastomotic leakage and quality management.¶Objective: In part three of the protocol, the three major sections include:¶ - The course of the individual patient using a comprehensive graphic display, including the perioperative period, hospital stay and post discharge outcome.¶ - A center based clinical practice guideline for the management of the most important postoperative complication - anastomotic leakage - including evidence based support for each step of the algorithm.¶ - Data management, ethics and organisational structure.¶Conclusions: Future studies with immune modifiers will also fail if not better structured (reduction of variance) to achieve uniform patient management in a complex clinical scenario. This new type of a single-centre trial aims to reduce the gap between animal experiments and clinical trials or - if it fails - at least demonstrates new ways for explaining the failures.¶
