Although previous studies have reported that AKI during cancer treatment was associated with poor oncological outcomes in several cancers, the impact of NAC-induced AKI on oncological outcomes in patients with MIBC remains unclear. METHODS: This retrospective study included 398 patients who received 2-4 cycles of NAC followed by radical cystectomy (RC). AKI was defined according to the KDIGO criteria. Patients were divided into two groups: patients who developed AKI during NAC (AKI group) and patients who did not (non-AKI group). Multivariable Cox-proportional hazards regression analyses were performed to evaluate the impact of NAC-induced AKI on recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS). RESULTS: The median age and follow-up period were 69 years and 62 months, respectively. Of the 398 patients, 66 (17%) developed AKI during NAC (Table 1). The rates of <ypT2 and downstage in the AKI group were significantly lower than those in the non-AKI group (Figure 1A and B). RFS, CSS, and OS in the AKI group were significantly shorter than those in the non-AKI group (Figure 1C-E). After adjustment for confounding variables, AKI was significantly associated with shorter RFS (hazard ratio [HR] 1.619, p=0.043), CSS (HR 1.727, p=0.049), and OS (HR 1.848, p=0.008) (Table 2). CONCLUSIONS: NAC-induced AKI was associated with reduced effects of NAC and poor oncological outcomes in patients who underwent RC.
