Abstract
Background:
Currently, there has been an increasing trend toward transanal endoscopic microsurgery as a definitive treatment of T1 rectal cancer. Despite the promising results from the earlier series, the more recent studies reported a higher rate of local recurrences.
Methods:
A retrospective analysis of 20 patients with T1 rectal cancer managed by transanal endoscopic microsurgery is presented.
Results:
The patients were followed-up for mean 39.3 months. Local recurrences occurred in 5.3% of low-risk, 50% of high-risk T1 cases. The 3-year and 5-year cancer-specific survival in T1 group were 94.4% and 73.5%, respectively with mean time without LR was 81.5 months (90.5 months in the low-risk and 21 months in the high-risk group).
Conclusion:
The results corroborate the excellent prognosis for low-risk T1 cancers treated by TEM alone. For a high-risk T1 cancer adjuvant radiotherapy or conventional resection is highly recommended.

Key words: early rectal cancer, transanal endoscopic microsurgery, risk factors, adjuvant radiotherapy
