Hypothesis

The study aimed to analyze the expression of Bmi-1 protein and its clinical significance in human bladder cancer.

Conclusion

Bmi-1 expression is greater in bladder cancers than in adjacent normal tissues and is potentially valuable in prognostic evaluation.

Supporting Evidence

  • Bmi-1 protein expression was higher in bladder cancers than in adjacent normal tissues.
  • 54.3% of bladder cancers showed Bmi-1 expression compared to 16.7% in normal tissues.
  • Higher Bmi-1 expression correlated with poorer survival rates.

Takeaway

Bmi-1 is a protein that can help doctors understand how serious a bladder cancer is; more of it means a worse outlook for patients.

Methodology

The study used RT-PCR, Western blot, and immunohistochemistry to analyze Bmi-1 expression in bladder cancer and adjacent normal tissues.

Limitations

The study used the old WHO grading system and did not record lymphovascular invasion.

Participant Demographics

137 patients, 115 males and 22 females, aged 14 to 72 years (mean 56 years).
