The value of EORTC risk tables in evaluating recurrent non-muscle-invasive bladder cancer in everyday practice.
BACKGROUND
Due to the risk of recurrence and progression, patients with non-muscle-invasive bladder cancer have to be under observation. The aim of this study is the evaluation of early recurrence at the first control cystoscopy, as a prognostic factor for recurrence and progression based on EORTC risk tables.


METHODS
This study analyzed 243 patients with non-muscle-invasive bladder cancer, with an average observation time of 46 months. Recurrence was observed in case of 99 patients. Among these patients, we selected 79 who had the first cystoscopy 3 months after the transurethral electroresection of the bladder tumor. Subsequently, 45 patients with early recurrence at the first control cystoscopy were compared with 34 patients whose cancer recurred at later control cystoscopies. The patients were compared with respect to the number of points assigned by EORTC tables.


RESULTS
Those patients who had an early recurrence had a significantly higher score in the EORTC table in the progression scale (p = 0.017) but not in the recurrence scale (p = 0.11), as compared with patients who had a late recurrence.


CONCLUSIONS
Early recurrence that occurs within 3 months after TURBT indicates a higher risk of progression, as compared with a late recurrence. Patients who had an early recurrence had a significantly higher EORTC risk score for progression. Their EORTC risk score for recurrence was also higher, but the difference was not statistically significant. Every patient with an early recurrence has a worse prognosis and a higher risk of progression.
