Hypothesis
Can a model effectively predict recurrence after radical cystectomy in bilharzial bladder cancer patients?
Conclusion
The model shows high sensitivity and specificity, making it suitable for predicting recurrence in patients after surgery.
Supporting Evidence
- The model classified 67 out of 72 patients who recurred as bad prognosis, achieving a sensitivity of 93%.
- The model classified 40 out of 50 patients without recurrence as good prognosis, achieving a specificity of 80%.
- The overall prognostic precision of the model was estimated at 88%.
Takeaway
Doctors can use a special formula to help figure out which bladder cancer patients might have a recurrence after surgery, so they can keep a closer eye on them.
Methodology
Retrospective analysis of patient records to evaluate a predictive model based on various clinical factors.
Potential Biases
No subject selection was performed, which helps reduce bias.
Limitations
The study relied on retrospective data, and some patients had missing information or could not be followed up.
Participant Demographics
122 patients, aged over 20, with bilharzial bladder cancer who underwent radical cystectomy.
Statistical Information
Confidence Interval
95% CI 83.5-97.5%
