Multicenter Analysis of Postoperative Complications in Octogenarians After Radical Cystectomy and Ureterocutaneostomy: The Role of the Frailty Index

BACKGROUND:The purpose of this study was to assess patient frailty as a risk factor for radical cystectomy (RC) complications. MATERIALS AND METHODS: We performed an analysis of prospectively collected data of consecutive patients 80 years of age or older who underwent RC and ureterocutaneostomy in 6 primary care European urology centers. Frailty was measured using a simplified frailty index (sFI) with a 5-item score including: (1) diabetes mellitus; (2) functional status; (3) chronic obstructive pulmonary disease; (4) congestive cardiac failure; and (5) hypertension, with a maximum 5-item score meaning high level of frailty. Within 90 days surgical complications were scored according to the Clavien Classification System (CCS). sFI ≥3 was considered as poor frailty status. Clinical and pathological variables were analyzed as predictors of severe complications (CCS ≥3). RESULTS: One hundred seventeen patients were enrolled. Most patients reported an sFI score of 2 and 3, respectively, 31/117 (26.5%) and 45/117 patients (38.5%). CCS ≥3 occurred in 17/117 patients (14.5%). Patients with sFI ≥3 were significantly older than patients with sFI <3 (median age, 85 years [interquartile range (IQR), 82-86] versus 82 years [IQR, 80-84]; P = .001). Most CCS ≥3 scores occurred in patients with sFI ≥3: 13 (11.1%) versus 4 (3.4%; P = .02). No significative differences were detected in terms of length of hospital stay, pathological stage, and postoperative bowel canalization when related to sFI. sFI ≥3 was an independent risk factor of CCS ≥3 in univariate and multivariate analysis (respectively, odds ratio [OR], 3.81 [95% confidence interval (CI), 1.16-12.5; P = .02] and OR, 3.1 [95% CI, 0.7-13.7; P = .01]). Body mass index, age, American Society of Anesthesiologists score ≥3, and pathological stage were not related to CCS ≥3. CONCLUSION: RC appears feasible in elderly patients with an sFI <3. In cases of sFI ≥3, this choice should be carefully valued, discussed, and possibly avoided because of a higher risk of complications.
