title: [The clinical value of the TSGF pre and post-therapy in patients with nasopharyngeal carcinoma(NPC)].
abstract: OBJECTIVE
  To investigate the role of TSGF (tumor supplied group of factor) in early diagnosing and predicting in patients with NPC.
  
  
  METHODS
  EBV-IgA and level of TSGF were measured before therapy and 1 month, 1 year after therapy in 35 patients with NPC, and the relationship between them was researched.
  
  
  RESULTS
  The diagnostic sensitivity of TSGF and EBV-IgA was 91%, 97% respectively, there is no significant relation between them. After treatment, the level of TSGF in PD (progression disease) patient remained higher, but had a significantly drop in RR(including the CR, PR and SI)) patient.
  
  
  CONCLUSIONS
  Results suggested that TSGF may be useful in diagnosing and prediction of NPC.
