ObjectiveTo assess the value of preoperative serum albumin level in predicting the survival of patients with non-muscle-invasive bladder cancer (NMIBC) undergoing transurethral resection of bladder tumor (TURBT).MethodsTwo hundred and sixteen newly diagnosed patients with NMIBC who underwent TURBT between January, 2007 and April, 2012 were retrospectively analyzed. The patients were categorized into low albumin (<40 g/L) and normal albumin (≥40 g/L) groups. The patient survival was estimated using the Kaplan-Meier method, and univariate and multivariate Cox proportional analyses were used to determine the hazard ratios (HRs) for the overall survival (OS).ResultsOf the patients with available data, 82 (39%) and 127 (61%) patients were classified into low albumin (<40 g/L) and normal albumin (≥40 g/L) groups, respectively. Kaplan-Meier analysis showed a significantly worse 5-year OS in low albumin group than in normal albumin group (P=0.017). In the multivariate Cox regression analysis, after adjusting for confounding variables, the preoperative albumin level remained as an independent predictor for 5-year OS (HR: 3.102, 95%CI: 1.200-8.020, P=0.020).ConclusionA low preoperative albumin level predicts a poor 5-year OS in patients with NMIBC who underwent TURBT. Preoperative serum albumin can be a good prognostic factor for predicting survival of the patients with NMIBC treated with TURBT.
