[Correlation between HLA-DRB1*0901 and 1501, HLA-DQB1*0301 and 0602 alleles and esophageal squamous cell carcinoma of Kazakh in Xinjiang, China].
OBJECTIVE
To investigate the polymorphism of HLA-DRB1 and DQB1 allele in esophageal squamous cell carcinomas of Kazakh in Xinjiang, and to characterize susceptible genes for the family of Kazakh esophageal squamous cell carcinoma.


METHODS
HLA-DRB1*0901, DRB1*1501, DQB1*0301, DQB1*0602 alleles were genotyped by sequence specific primers using polymerase chain reaction (PCR-SSP) in 200 Kazakh esophageal squamous cell carcinoma and 177 normal esophageal mucosa.


RESULTS
The frequency of HLA-DRB1*1501, HLA-DQB1*0301, HLA-DQB1*0602 alleles in 200 Kazakh esophageal squamous cell carcinoma (0.455, 0.760 and 0.690) were significantly higher than that of 177 normal esophageal mucosa (0.232, 0.520, 0.554; OR = 2.78, 2.93, 1.80; P < 0.05). The frequency of HLA-DRB1*0901 between the carcinoma (0.105) and control groups (0.102) had no association (OR = 1.036, P > 0.05); The frequency of HLA-DQB1*0602 was higher in poor-differentiated squamous cell carcinomas (0.742) than that of well-differentiated tumors (0.597, P < 0.05).


CONCLUSIONS
HLA-DRB1*1501, HLA-DQB1*0301, HLA-DQB1* 0602 may be susceptible to Kazakh esophageal squamous cell carcinoma. HLA-DQB1*0602 correlates with well-differentiated esophageal squamous cell carcinoma.
