Abstract

Introduction

We conducted this study to determine if, in appropriately selected elderly patients receiving neoadjuvant chemotherapy (NAC), clinical outcomes including pathologic complete response/downstaging and overall survival were similar to a younger cohort.

Methods

Chart review was performed on patients receiving NAC for urothelial carcinoma of the bladder (UCB) from 2004 to 2013. A total of 116 patients were identified that underwent NAC from 2004 to 2013 for ≥ cT2N0M0 UCB. Patients were excluded who received 2 cycles or less of chemotherapy (N = 18; 11 patients in the younger cohort, 7 in the elderly group; P = .74). Data was analyzed, and Kaplan-Meir analysis curves were used for survival and recurrence.

Results

Forty-six elderly patients (age ≥ 70 years) (67% cisplatin-based regimen) were identified and compared with 70 (93% cisplatin-based regimen) younger patients. The estimated glomerular filtration rate, performance status, preoperative hemoglobin, and body mass index were significantly worse in elderly patients. Dose reduction and pathologic downstaging to non–muscle-invasive disease was not statistically different between older and younger patients Complete pathologic response in older patients (16%) and in the younger cohort (17%) were similar (P = .146). There was no significant difference in follow-up, recurrence, or in median overall survival between patient groups (28 months elderly vs. 35 months younger; P = .78). Age was not an independent predictor of pathologic downstaging, complete response, overall survival, or recurrence-free survival.

Conclusions

NAC in elderly patients (≥ 70 years old) demonstrated equivalent toxicity and oncologic outcomes in our single-institution cohort. Although older patients had significantly poorer performance status and renal function, there were no differences in survival or response to NAC.

Micro-Abstract

This study evaluated elderly patients with urothelial carcinoma of the bladder receiving neoadjuvant chemotherapy (NAC). Compared with a younger cohort of patients, NAC demonstrated equivalent toxicity and oncologic outcomes in our single-institution cohort. Although older patients had significantly poorer performance status and renal function, there were no differences in survival or response to NAC.
