Hypothesis
The study aims to verify if the associations between HLA class II polymorphisms and invasive cervical cancer (ICC) risk are influenced by HPV-16 variability.
Conclusion
The association between HLA polymorphism and risk of ICC might be influenced by the distribution of HPV-16 variants.
Supporting Evidence
- HPV-16 variants from E, AA, Af-1 and Af-2 branches were identified in 107 cases.
- An inverse association between DQB1*05 and ICC was found, particularly in AA variant carriers.
- A positive association with DRB1*15 was observed in both E and AA variant groups.
Takeaway
This study looks at how different types of HPV-16 can affect the risk of cervical cancer and how our genes might play a role in that risk.
Methodology
The study involved 107 ICC cases and 257 controls, with HPV-16 variants characterized by PCR and HLA typing performed on all participants.
Potential Biases
Potential biases may arise from the selection of cases and controls and the reliance on self-reported risk factors.
Limitations
The study's findings may not be generalizable due to the specific population studied and the small number of African variant cases.
Participant Demographics
Participants included women with histopathologically confirmed squamous ICC and controls with normal or inflammatory Pap smears, primarily from Brazil.
