  1. P# denotes patient number. Information includes - Site of original cancer (cancer site); tumour size (T); nodal status (N); evidence of metastasis (M); evidence of perineural invasion (P); evidence of vascular invasion (V); evidence of extracapsular invasion (E); whether the margin was involved with tumour after surgery or clear; differentiation of the tumour (Diff); Site of recurrence (Recurrence); whether (Y), or not (n), radiation was given post-surgery (Radiation) including dosage - Grays (Gy) in fractions; whether (Y), or not (n), chemotherapy was given (Chemo); the outcome at last follow-up (Outcome); and whether the patients were positive (POS) or negative (neg), before and after surgery for at least 2 of the RT-PCR markers. Y denotes yes, n denotes no, x denotes unknown.
