title: [TGF beta subtypes in hepatocellular carcinoma].
abstract: OBJECTIVE
  To detect the expression of three TGF beta isoforms and its clinicopathologic significance in hepatocellular carcinoma(HCC).
  
  
  METHODS
  Surgical specimens of 52 patients with small HCC resection during 1992-1995 were used to determine the immunoreactivity of TGF beta protein by ABC immunohistochemistry. These specimens were divided into recurrence group(G1) and recurrence group(G2) according to whether HCC recurred two years after resection. The relations with recurrence of HCC were analyzed.
  
  
  RESULTS
  The positive rates in G1 and G2 were 85% (17/20) versus 47% (15/32) for TGF beta 1, 90% (18/20) vs. 78% (25/32) for TGF beta 2, and 45% (9/20) vs. 63% (20/32) for TGF beta 3. Significant difference was found in TGF beta 1 and TGF beta 2, but not in TGF beta 3.
  
  
  CONCLUSIONS
  The high immunoreactivity to TGF beta 1 or TGF beta 2 is positively related to the recurrence of HCC.
