title: [A primary study of the association of human leucocyte antigen and osteosarcoma].
abstract: OBJECTIVE
  To study the association of human leucocyte antigen and osteosarcoma in Chinese Han nationality.
  
  
  METHODS
  The frequencies of HLA-A,B,DR,DQ locus antigens were tested in a group of 25 osteosarcoma patients and in a control group of 250 healthy persons by using complement-dependent microlymphocytoxity technique. The members of both groups were of Chinese Han nationality. Their results were compared statistically.
  
  
  RESULTS
  The frequency of HLA-B35 was 0.400 in patient group and 0.048 in the control group. The relative risk of suffering from osteosarcoma in persons carrying HLA-B35 was 13.220 times as high as that in those without this antigen (P < 0.01). Patients with HLA-B13 had 12.048 fold increase in relative risk with poor prognosis compared to those without this antigen (P < 0.05). A tendency of worst prognosis was seen in patients who carried both HLA-B13 and HLA-B35, but patients with HLA-B40 had 7.057 times better relative safety for good prognosis than those without that antigen (P < 0.05).
  
  
  CONCLUSIONS
  HLA-B35 is in close linkage to osteosarcoma susceptible gene in Chinese Han nationality. HLA-B13 and HLA-B40 may be separately related to the malignant and resistant genes of osteosarcoma.
