Abstract

Introduction: The UK Medical Research Council CLASICC trial assessed the safety and efficacy of laparoscopically assisted surgery in comparison with open surgery for colorectal cancer. The results of the 5-year follow-up analysis are presented. Methods: Five-year outcomes were analysed and included overall and disease-free survival, and local, distant and wound/port-site recurrences. Two exploratory analyses were performed to evaluate the effect of age (70 years or less, or more than 70 years) on overall survival between the two groups, and the effect of the learning curve. Results: No differences were found between laparoscopically assisted and open surgery in terms of overall survival, disease-free survival, and local and distant recurrence. Wound/port-site recurrence rates in the laparoscopic arm remained stable at 2·4 per cent. Conversion to open operation was associated with significantly worse overall but not disease-free survival, which was most marked in the early follow-up period. The effect of surgery did not differ between the age groups, and surgical experience did not impact on the 5-year results. Conclusion: The 5-year analyses confirm the oncological safety of laparoscopic surgery for both colonic and rectal cancer. The use of laparoscopic surgery to maximize short-term outcomes does not compromise the long-term oncological results. Registration number: ISRCTN74883561 (http://www.controlled-trials.com).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
