Background
Fibrous tissue around a locally recurrent rectal tumour is an interesting histological feature, but its clinicopathological significance has not been investigated.
Method
This retrospective study examined clinicopathological findings in 48 patients who underwent curative total pelvic exenteration with distal sacrectomy (TPES) between 1992 and 2004. Data were analysed with respect to fibrosis around the recurrent tumour, categorized into one of three groups: no fibrosis (f0), partial fibrosis (f1) or circumferential fibrosis (f2).
Results
Ten, 17 and 21 patients had f0, f1 and f2 fibrosis respectively, with 5‐year survival of none, four and eight patients respectively. The overall survival of patients with circumferential fibrosis was significantly better than that in patients with no fibrosis (P = 0·003). Univariable analysis showed that a high level of sacrectomy (P = 0·036), absence of lymphatic invasion (P = 0·031) and circumferential fibrosis (P = 0·039) were significantly associated with better overall survival. In multivariable analysis, circumferential fibrosis (P = 0·031) and low serum carcinoembryonic antigen levels (P = 0·044) were independent factors for a favourable outcome.
Conclusion
The outcome of patients with locally recurrent rectal cancer after curative TPES appears to be better when circumferential fibrosis is present around the tumour. Copyright © 2007 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.
