title: [Clinical value of tumor-associated growth factor detection in the diagnosis of colorectal carcinoma].
abstract: OBJECTIVE
  To investigate the diagnostic value of tumor-supplied growth factors (TSGF) in patients with colorectal carcinoma.
  
  
  METHODS
  The serum content of TSGF was determined in 71 patients with colorectal carcinoma 71, 55 with benign tumor, and 100 healthy volunteers with colorimetry.
  
  
  RESULTS
  TSGF concentration and its positivity rate were both significantly higher in colorectal carcinoma patients (81.5 x 10(3) U/L/71%) than in normal controls (55.7 x 10(3) U/L/3%) and patients with benign tumor (57.2 x 10(3)U/L/7.4%).TSGF positivity rate was independent of the patients' age, gender and stage of colorectal carcinoma. The diagnostic sensitivity of TSGF was 71% for colorectal carcinoma, higher than that of carcinoembryonic antigen (43.7%).
  
  
  CONCLUSIONS
  TSGF is more sensitive than carcinoembryonic antigen for early diagnosis of colorectal carcinoma.
