As a result, the NDP positive rate in nasopharyngeal carcinoma (NPC) (95.54%) markedly increased (P<0.05), as compared with that in the normal nasopharyngeal epithelia (50.00-60.00%) and lymphocytes (52.00%).

Their positive rates were 64.44%, 15.56% and 20.00% respectively in nasopharyngeal carcinoma. The expression of NDP had no relation with cervical lymphometastases in NPC, and the NDP positive rates had no significance between bilateral cervical lymphometastases and unilateral (P<0.05). But the NDP expression had most relation with the NPC staging. The expression rate and the intensity in Ⅲ or Ⅳ stage patients were markedly higher than that in II stage. It points out that the high-level expression of NDP had relation with the rapid cellular proliferation in NPC, and it may indicate the bad prognoses.展开更多
