Local recurrence rate. We compared the local recurrence rate of the referred patients based on the presence or absence of residual tumor at re-excision (Chi2 test). The local recurrence rate after re-excision of residual tumor was 15.63 % (11 cases), compared to 6.25 % (4 cases) when no residual tumor was found. Although the difference was not significant, there was a strong tendency towards significance (p = 0.057)
