  1. 1 Grade of Tumour was not documented in 5 patients and outcome information was missing in 22.
  2. 2 Margin status was not documented in 31 patients and outcome information missing for 10 patients
  3. Grade of the tumour was classified pathologically as high or low grade. The margin was considered positive if tumour was present within 1 mm of resected specimens. The p-values were statistically significant for the grade of the tumour and the margins status post-operatively in determining the relapse of the disease.
