Prediction of survival after radical cystectomy for invasive bladder carcinoma: risk group stratification, nomograms or artificial neural networks?
In this study artificial neural networks outperformed the risk group stratification model and nomogram construction in predicting patient 5-year survival probability, and in terms of sensitivity and specificity.
Our study showed significant improvement in patients with symptoms beyond 1 as well as 2 years since onset, and surgery is a viable option in selected patients.
