title: [Clinical value of combined detection of LDH, TPS, CEA and beta2-MG in patients with non- Hodgkin's lymphoma].
abstract: OBJECTIVE
  To study the clinical value of combined detection of 4 tumor markers, namely lactic dehydrogenate (LDH), tissue polypeptide specific antigen (TPS), carcinoembryonic antigen (CEA) and beta2-microglobulin (beta2-MG) in patients with non-Hodgkin's lymphoma (NHL).
  
  
  METHODS
  The serum level of LDH was determined with automatic biochemical analyzer and TPS, CEA and beta2-MG levels were determined by enzyme-linked immumosorbent assay (ELISA) in 59 patients with NHL and 40 healthy adults.
  
  
  RESULTS
  The levels of the 4 tumor markers were significantly higher in NHL patients than in the healthy control subjects (P<0.05). After chemotherapy, the serum levels of TPS and beta2-MG were significantly lowered in the patients who showed favorable response to the treatment (P<0.05), but the levels of LDH and CEA showed no significant change (P>0.05). The serum levels of LDH, TPS, CEA and beta2-MG in the patients in a stable or progressive phase did had no significant changes after chemotherapy (P>0.05).
  
  
  CONCLUSIONS
  Combined detection of LDH, TPS, CEA and beta2-MG can be helpful to assist diagnosis of NHL and treatment evaluation.
