  1. a SD: standard deviation b Based on the Student t-test cHistological type : SCC : squamous cell carcinoma, NKC : non-keratinizing carcinoma, UC : undifferentiated carcinoma. d Clinical staging: primary tumor extension classified T2, T3 or T4 according to AJCC/UICC (1997); regional lymph node extension classified N0 in the absence of clinical or radiological evidence of lymph node invasion at the initial workup, N+ in the other cases; metastatic status defined as M0 in the absence of clinical or radiological evidence of distant metastasis at the initial workup, M+ in the other cases (synchronous metastases). eNA : not applicable.
