Abstract
To evaluate the effects of (125)I seed implantation in sphincter preservation for treatment of low rectal cancer. Seventy-six patients with low rectal cancer were randomly divided into 2 group: group A, 17 males and 13 females, aged 48.5 +/- 2.4, receiving rectostomy and anal sphincter preservation and group B, 24 males and 22 females, aged 49.4 +/- 2.6, receiving modified TME and anal sphincter preservation combined with brachytherapy by (125)I seed implantation. Two to four weeks after operation chemotherapy with 5-FU/CF were performed. Follow-up was carried out 6, 12, 24, and 36 months after operation. The local recurrence rates 6, 12, 24, and 36 months after operation were 0%, 11.1%, 14.3%, and 23% respectively in the group A, and all 0% in the group B (P < 0.05 for the rate 36 months later). The survival rates 6, 12, 24, and 36 months after operation were 100%, 100%, 85.7%, and 76.7% respectively in the group A, and were 100%, 100%, 97.1%, and 93% respectively in the group B (P < 0.05 for the rate 36 months later). The functions of defecation and erection were better in the group B and the symptom of pain was improved better in the group A too (all P < 0.05). Safe, simple, and effective, surgery with sphincter preservation combined with brachytherapy in low rectal cancer is one of the ideal methods for treatment of low rectal cancer.
