Hypothesis

Understanding the HPV genotype distribution in invasive cervical cancer (ICC) is essential for vaccine optimization.

Conclusion

The study suggests that incorporating the bivalent vaccine into the national program is cost-effective and can guide future prevention strategies.

Supporting Evidence

  • The overall prevalence of HPV infection was 94.9% among 1,908 women with ICC.
  • HPV genotypes 16 and 18 were detected in 90.9% of HPV-positive patients.
  • HPV genotypes contained in the 9-valent vaccine were detected in 98.1% of patients.
  • The cumulative attribution rates of the bivalent vaccine was 83.4%.
  • The cumulative attribution rates of the nine-valent vaccine was 89.8%.

Takeaway

This study looked at how common different types of HPV are in women with cervical cancer in western China, which can help improve vaccines.

Methodology

DNA was extracted from 1,908 paraffin-embedded ICC samples, and 23 HPV genotypes were detected via PCR and reverse dot hybridization gene chip assays.

Potential Biases

The study may be influenced by the COVID-19 outbreak and policies during data collection.

Limitations

Selection bias may be present due to the retrospective nature of the study and the small sample size of patients with rare carcinomas.

Participant Demographics

The study included 1,908 female patients with ICC from 12 provinces in western China.
