Any significant differences in local, regional or
distant metastasis or in recurrence-free survival
At 3 years free from local recurrence: 96% vs 100%
Regional nodal recurrence: 4 vs 1 patients
Free from regional recurrence at 3 years: 90% vs 96%
Distant metastasis: 1 vs 2 patients
Free from distant metastasis at 3 years: 97% vs 91%
Recurrence free survival at 3 years: 86% vs 80%
Small number of events:
statistical power to detect
significant difference in local, regional and distant failure
was low. Relapse frequencies and recurrence-free survival
are preliminary for short follow-up
