Fig. 2 Percentage of completely downstaged tumours stratified over the clinical T stages and study arms. A significant increase in complete downstaging was observed in the neoadjuvant arm when comparing all tumours (p=0.006) and cT3 tumours (p=0.014).

Fig. 3 Percentage of noninvasive downstaged tumours stratified over clinical T stages and study arms. The neoadjuvant arm revealed a significant increase in noninvasive downstaging when comparing study arms for all tumours (p=0.001), clinical T2 tumours (p=0.024), and clinical T3 tumours (p=0.005).

Fig. 4 Percentage of organ-confined tumours stratified over clinical T stages and study arms. Clinical T3 tumours were the only group in which a significant difference appeared between the study arms, revealing a 16.9% increase in organ-confined tumours in favour of the neoadjuvant arm (p=0.009).

Fig. 5 Overall survival of 449 cystectomised patients stratified into four groups. Patients with completely downstaged tumours in the neoadjuvant arm (blue) exhibited an 88.2% 5-yr survival rate compared with 57.1% in patients with completely downstaged tumours in the control arm (green) (p=0.001). Nondownstaged tumours in the neoadjuvant (yellow) and in the control arm (orange) indicated nonsignificant survival differences. CD=complete downstaging; Ctrl=control; NAC=neoadjuvant chemotherapy.

Fig. 6 Overall survival of 449 cystectomised patients stratified into four patient groups. Patients with noninvasive downstaging (NID) tumours in neoadjuvant arm (blue) had a 5-yr survival of 83% compared with 65% in NID controls (green) (p=0.018). Patients with non-NID tumours in the neoadjuvant arm (yellow) and non-NID controls (orange) showed nonsignificant survival differences. Ctrl=control; NAC=neoadjuvant chemotherapy.

Fig. 7 Overall survival of 449 cystectomised patients stratified into four groups. Patients with organ-confined (OC) tumours in the neoadjuvant arm (blue) exhibited a 77.5% 5-yr survival compared with 64.6% in patients with OC in the control arm (green) (p=0.005). No statistical difference in survival was observed between patients with non–organ-confined (NOC) tumours in the neoadjuvant arm (yellow) and NOC tumours in the control arm (orange). Ctrl=control; NAC=neoadjuvant chemotherapy. European Urology , DOI: ( /j.eururo ) Copyright © 2011 European Association of Urology Terms and Conditions
