Keys:
Diff = Differentiation: 1=poorly diff; 2=moderately diff; 3= well diff
LV = presence or absence of lymphatic/vascular invasion: as binary logicals (Yes =1; No=0)
PN spread= Presence/Absence of perineural spread: as binary logicals (Yes=1; No=0)
Radiotherapy (RT): 0= no RT; 1= primary RT; 2= chemo/RT; 3= post-op RT (administered after biopsy specimen obtained); 4= re-irradiation for recurrence Stage”
X = not detectable
T = Tumor Size; N= regional node status; M= presence/absence of distant metastasis
Subsite: TG= tongue; BM= buccal mucosa; RMT= retromolar trigone; FOM= floor of mouth; SP= soft palate
