AI Article Synopsis
- The study investigates the link between GSTM1 and GSTT1 gene variations and osteosarcoma risk in a Chinese population.
- Data was collected from 110 osteosarcoma patients and 226 controls, with genotyping conducted using a specific PCR method.
- Findings suggest that individuals with null GSTM1 and GSTT1 genotypes have a significantly higher risk of developing osteosarcoma, particularly in males and younger individuals aged 15 or under.
Article Abstract
Aim: We aimed to study the potential role of GSTM1 and GSTT1 in the risk of osteosarcoma in Chinese population.
Methods: We collected 110 osteosarcomas by pathologic examination and 226 controls from the First Affiliated Hospital of Harbin Medical University during December 2008 to December 2010. Genotyping was based upon duplex polymerase-chain-reaction with the PCR-CTPP method.
Results: Individuals carrying null GSTM1 and GSTT1 had 1.50 and 2.07 fold risks of osteosarcoma when compared with non-null genotypes, respectively. The increased risk associated with the GSTT1 polymorphism seemed more evident among males (Null GSTT1 genotype vs. non-null genotype, adjusted OR= 2.43, 95% CI: 1.29-3.30) than females (adjusted OR =1.66, 95% CI: 1.02-2.78). The increased risk was also more evident among individuals aged 15 years or less (adjusted OR for null GSTT1 genotype vs. non-null genotype = 2.24, 95% CI: 1.20-3.24) than those aged more than 15 years (adjusted OR = 1.82, 95% CI: 1.07-2.95).
Conclusion: Our study of the association between polymorphisms in GSTM1 and GSTTI and the risk of osteosarcoma in a Chinese population provided evidence that null GSTTI might be a useful marker of susceptibility to osteosarcoma development, especially for male sand young age individuals.
