Abstract: Objective To investigate the treatment of local recurrence after sphincter preserving surgery for low rectal cancer. Methods Fifty-six patients with local recurrence after sphincter preserving surgery for low rectal cancer were divided into three groups, 20 cases underwent radical resection (group A), 21 cases underwent palliative resection combined with 3 dimensional conformal radiation therapy (group B), and 15 cases only received 3 dimensional conformal radiation therapy (group C). Results All the patients were followed up from 6 months to 3 years. The 1-year,2-year and 3-year survival rates were 100.0%(20/20),80.0% (16/20),65.0% (13/20) in group A,90.5% (19/21),52.4% (11/21),33.3% (7/21) in group B and 80.0%(12/15),40.0%(6/15),20.0%(3/15) in group C respectively. Both 2-year and 3-year survival rates in group A were significantly higher than those in group B and group C (P <0.05). Conclusions The first choice of patients with local recurrence after sphincter preserving surgery for low rectal cancer is radical resection. Palliative resection combined with 3 dimensional conformal radiation therapy is the second choice.
