Local recurrence of rectal cancer is the result either of potentially removable tumor cells left in situ or cells already disseminated to areas where surgery cannot reach them. The first scenario infers inadequate surgery, the second implies unfavorable biology. Surgeons who operate for rectal cancer must know local recurrence rates in their patients, and be able to relate them to outcomes achieved by others. We have performed this study to facilitate such a comparison. Methods: Systematic review of the literature from 1990 to 2010 was performed for publications which reported local recurrence after proctectomy for rectal cancer. Inclusion criteria were: studies of more than 80 patients and local recurrence stratified by histopathologic stage. Pooled local recurrence rates were tabulated by 5 percentile levels, stratified according to TNM stage (I,II,III) and surgical technique (total mesorectal excision or standard), as well as laparoscopic versus open. Results: Thirty-six studies comprising 16425 patients were pooled for final analysis: Mean follow-up is 40.9 months (1.3-188mths). The table shows local recurrence stratified by tumor biology (stage), operative technique (total mesorectal excision vs. standard) and operative approach (open vs. laparoscopic). The percentiles provide standards against which surgeons can compare their own outcomes Conclusion: Oncologic outcome of the treatment of rectal cancer is the result of interaction of therapeutic expertise and tumor biology. The percentile tables allow the use of local recurrence rates as an indirect parameter of surgical quality.
