Hypothesis

The emergence of the rtA181T/sW172* mutant increases the risk of hepatoma occurrence in patients with lamivudine-resistant chronic hepatitis B.

Conclusion

The rtA181T/sW172* mutant in lamivudine-resistant patients significantly increases the risk of developing hepatocellular carcinoma.

Supporting Evidence

  • 3 of the 10 rtA181T-positive patients developed hepatocellular carcinoma.
  • 2 of the 113 rtA181T-negative patients developed hepatocellular carcinoma.
  • Age over 50 years and liver cirrhosis were also significantly associated with HCC.

Takeaway

If patients with hepatitis B develop resistance to a drug called lamivudine, they might have a higher chance of getting liver cancer, especially if they have a specific mutation.

Methodology

Serum samples from 123 LAM-resistant chronic hepatitis B patients were analyzed using a sensitive method to detect the rtA181T mutant and assess clinical outcomes.

Potential Biases

There may be biases related to the selection of patients and the retrospective nature of the data collection.

Limitations

The study is limited by its retrospective design and the potential for unmeasured confounding factors.

Participant Demographics

Patients were predominantly male, with a mean age of 58.5 years for those with the rtA181T mutation.
