Hypothesis
The study investigates the correlation between Ki-67 index and prognostic factors in bladder carcinoma.
Conclusion
The Ki-67 index is significantly correlated with T stage and histological grade in bladder carcinoma, indicating its potential as a prognostic marker.
Supporting Evidence
- The Ki-67 index ranged from 3.0-65.8%, with a mean of 20.2%.
- Patients with invasive disease had significantly higher Ki-67 indices than those with non-invasive disease.
- Ki-67 index correlated positively with T stage and histological grade.
Takeaway
This study looks at how a special test can help doctors understand how fast bladder cancer is growing, which can help in deciding the best treatment.
Methodology
The study examined 69 bladder biopsies from 64 patients using Ki-67 immunostaining to assess tumor proliferation.
Limitations
Some specimens showed no Ki-67 labeling, and the clinical importance of Ki-67 can only be inferred from correlations with known prognostic factors.
Participant Demographics
The participants included 46 males and 18 females, aged 45-92 years, with primary bladder carcinoma.
