Thefactor predicting prognosis in NPC was N_3, The positive expression of VEGF andLMP-1.Conclusions: VEGF and LMP-1 being highly expressed in NPC, is apt to be usedof predictor of prognosis.

• 鼻咽癌预后不良的危险因素是颈淋巴结状态为N_3；VEGF表达阳性及LMP-1表达阳性(p<0.；05)。 结论:VEGF；LMP-1在鼻咽癌中的阳性表达；与颈淋巴结转移明显相关；LMP-1能上调VEGF表达；从而增强鼻咽癌的转移潜能。
