Effect of Preoperative Nutritional Deficiency on Mortality After Radical Cystectomy for Bladder Cancer
Open accessAbstract
PURPOSE: Poor preoperative nutritional status is a risk factor for adverse outcomes after major surgery. We evaluated the effect of preoperative nutritional deficiency on perioperative mortality and overall survival in patients undergoing radical cystectomy for bladder cancer. MATERIALS AND METHODS: A total of 538 patients underwent radical cystectomy for urothelial carcinoma between January 2000 and June 2008, and had nutritional parameters documented. Patients with preoperative albumin less than 3.5 gm/dl, body mass index less than 18.5 kg/m(2) or preoperative weight loss greater than 5% of body weight were considered to have nutritional deficiency. Primary outcomes were 90-day mortality and overall survival. Survival was estimated using Kaplan-Meier analysis and compared using the log rank test. Cox proportional hazards models were used for multivariate survival analysis. RESULTS: Of 538 patients 103 (19%) met the criteria for nutritional deficiency. The 90-day mortality rate was 7.3% overall (39 deaths), with 16.5% in patients with nutritional deficiency and 5.1% in the others (p < 0.01). Nutritional deficiency was a strong predictor of death within 90 days on multivariate analysis (HR 2.91; 95% CI 1.36, 6.23; p < 0.01). Overall survival at 3 years was 44.5% (33.5, 54.9) for nutritionally deficient patients and 67.6% (62.4, 72.2) for those who were nutritionally normal (p < 0.01). On multivariate analysis nutritional deficiency cases had a significantly higher risk of all cause mortality (HR 1.82; 95% CI 1.25, 2.65; p < 0.01). CONCLUSIONS: Nutritional deficiency, as measured by preoperative weight loss, body mass index and serum albumin, is a strong predictor of 90-day mortality and poor overall survival. Prospective studies are needed to demonstrate the best indices of preoperative nutritional status and whether nutritional intervention can alter the poor prognosis for patients treated with radical cystectomy who have nutritional deficiencies.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
