Objective:
To investigate the clinicopathologic factors related with recurrence and prognosis after surgical resection for I stage lower rectal carcinoma.
Methods:
The related clinicopathologic factors for recurrence and prognosis of 166 patients with I stage lower rectal carcinoma after surgical resection were retrospectively analyzed using univariate and multivariate methods.
Results:
A total of 138 patients with I stage lower rectal carcinoma received radical resection according to the operative rules of total mesorectal excision (TME). Ninety-three patients received abdominoperineal resection (APR) operation, 45 patients received sphincter preserving operation, and 28 patients received local excision. The local recurrence rates were 6.5% (6/93), 2.2% (1/45), 17.9% (5/28), respectively . Histological differentiation and operative procedures were associated with local recurrence. The 5-year survival rates were 91.1% in APR group, 95.5% in sphincter preservation group and 82.6% in local resection group. Univariate analysis revealed that histological differentiation and local recurrence were correlated with prognosis. Multivariate analysis revealed that local recurrence was the most important prognostic factor for I stage lower rectal carcinoma.
Conclusions:
Radical resection of I stage lower rectal carcinoma has low recurrence rate and better prognosis. Sphincter preserving operation and local excision must be strictly selected in proper patients.
