Abstract:
Objective To explore selective criteria of sphincter preservation operation(SPO) for middle to low third rectal cancer,and analyze clinicopathologic parameters resulting in the selective criteria.Methods Two hundred and seventy-nine cases of middle to low third rectal cancer who accepted operative treatment from 1996 to 2004 were analyzed retrospectively.One hundred and eighty-seven rectal tumours were located in 5-10 cm from anus,92 rectal tumours in below 5 cm from anus.Among them 127 cases were treated by abdominal-perineal resection(APR),and 152 cases were treated by SPO in which there were 130 Dixon operations,12 Bacon operations,and 10 Parks operations.Clinicopathologic parameters and survival rate in APR and SPO groups were compared statistically.Results Gender,age,size,tumor types,site of tumor,degree of differentiation,infiltrated circumference of intestine,and lymph node metastasis,depth of invasion and Dukes stages were not significantly different between APR and SPO groups.SPO performed rate was 54.48% in all.SPO was performed in 48 lower third rectal cancer cases(52.17%,48/92).Regional recurrence rate was 6.81%(19/279).Middle survival time was((65.00?6.87))months and 5-year survival rate was 63.51% in SPO group.Middle survival time was((52.23?5.63)) months and 5-year survival rate was 52.50% in APR group.Chi-Suqare was 18.14 by Log-rank test(P=0.054 1).Conclusion There is no statistically difference in survival rate between APR and SPO groups.
