AimWe undertook this study to evaluate the influence of resection margin distance from metastases on survival and post-operative disease recurrence after hepatectomy for colorectal liver metastasis.MethodsBetween January 1993 and December 2001, 293 consecutive patients underwent primary liver resection for colorectal metastasis. Clinical, pathological and outcome data were analysed using a prospectively collected database. Cases were stratified into those with involved and non-involved resection margins. Different non-involved margin widths were analysed against survival, recurrence rate and pattern (hepatic, extra hepatic) of recurrence.ResultsThe 1, 3, 5 and 10 years actuarial survival rates were 82, 58, 44 and 36%, respectively. The median survival was 46 months. The histological liver resection margin involvement was a significant predictor of survival and disease free survival after surgery. One, two, five and 10 millimetres disease free resection margin widths were found not to be significant in influencing patients' survival or recurrence rate.ConclusionA positive hepatic resection margin was associated with a higher incidence of post-operative recurrence and lower survival rate. The width of the resection margin did not influence the post-operative recurrence rate or pattern of recurrence. The ‘1 cm rule’ should be abandoned.
