title: [Analysis of clinicopathological features and prognostic factors of 62 nasal NK/T-cell lymphomas].
abstract: OBJECTIVE
  To investigate the clinicopathological features and prognostic factors of nasal NK/T-cell lymphoma.
  
  
  METHODS
  The clinicopathological data, treatment modality and survival status were analyzed.
  
  
  RESULTS
  The overall five year survival rate of: 62 patients was 63.5%. In univariate analysis, the prognosis of the patients was correlated with the age, perforation, B symptom, stage, Hb concentration, LDH level, size of tumor cell, number of involvement sites, angioinvasion and treatment modality (P < 0.05 or P <0.01). In multivariate analysis, the Hb concentration, the size of the tumor cell and the treatment modality were the independent prognostic factors.
  
  
  CONCLUSIONS
  The Hb concentration, the size of the tumor cell and the treatment modality play key role in the prognosis of nasal NK/T-cell lymphoma.
