Answer

The circumferential resection margin positivity rate is about 5% or less for low anterior resections with TME, whereas it is between 10% and 25% for abdominoperineal excision of the rectum. There is, understandably, a higher local recurrence rate following abdominoperineal excision of the rectum. The 5-year survival and disease-free survival rates are significantly lower with TME.

Evidence suggests that a circumferential resection margin of 1 mm or less adversely affects cancer-specific survival, local recurrence, and distant metastasis. [2]
