１９８０～１９９０年，作者行直肠癌治愈性切除术共１６０例，随访４年～１４年。术后复发及转移４４例（２７．５％）。再次手术１７例（３８．６％）。其中治愈性切除６例（１３．６％），姑息性切除５例（１１．４％），单纯结肠造瘘６例（１３．６％）。全部再手术患者有６例生存超过５年，５年生存率３５．３％，未经手术治疗者无１例存活超过５年，两者比较差异非常显著（ｐ＜０．００５）。即使行姑息手术者，２年生存率（６３．６％）也明显高于非手术组（３７％，Ｐ＞０．０５）。可见对直肠癌术后复发或转移再次手术不仅可以改善症状，提高生存质量，而且部分患者可获长期生存。
From 1980 to 1990, the author performed a total of 160 cases of curative resection of rectal cancer, followed up for 4 years to 14 years. Postoperative recurrence and metastasis in 44 cases (27.5%). Reoperation in 17 cases (38.6%). Among them, 6 cases (13.6%) were treated with curative resection, 5 cases (11.4%) with palliative resection, and 6 cases (13.6%) with simple colostomy. Six patients in all reoperations survived more than 5 years. The 5-year survival rate was 35.3%. None of the untreated patients survived more than 5 years. There was a significant difference between the two groups (p<0.005). Even with palliative surgery, the 2-year survival rate (63.6%) was significantly higher than the non-surgical group (37%, P>0.05). It can be seen that reoperation for rectal cancer after recurrence or metastasis can not only improve the symptoms and improve the quality of life, but also some patients can achieve long-term survival.
