ABSTRACT
PURPOSE: Radical cystectomy (RC) can be associated with significant blood loss, whereas many patients are presenting with anemia preoperatively. To date, there is a lack of data addressing the impact of preoperative anemia (PA) on survival of patients undergoing RC for urothelial carcinoma of the bladder (UCB). METHODS: This retrospective multicenter study includes 684 patients with UCB undergoing RC with pelvic lymph node dissection. The median follow-up was 50 (IQR 29,78) months. Anemia was defined in line with the WHO classification (hemoglobin (Hb): male ≤13 g/dL, female ≤12 g/dL) and based on contemporary gender- and age-adjusted classification (Hb: white male aged <60 years: ≤13.7 g/dL; ≥60 years: ≤13.2 g/dL; white female of all ages ≤12.2 g/dL). Univariable and multivariable Cox regression analyses were used to assess the effects of PA on oncological outcomes. RESULTS: A total of 269 (39.3 %) and 302 (44.2 %) patients were anemic according to the WHO classification versus contemporary classification. Age, increased ECOG performance status, advanced tumor stages, lymph node metastasis, positive surgical margin and anemia were associated with disease recurrence (DR), cancer-specific mortality (CSM) and all-cause mortality (ACM). In multivariable analysis, anemia was an independent predictor of DR, CSM and ACM (WHO and/or contemporary classification). Blood transfusion was significantly associated with ACM in both classifications of anemia. CONCLUSIONS: PA is significantly associated with worse oncological outcome in patients undergoing RC. Based on the additional unfavorable influence of blood transfusion, this emphasizes the importance of early diagnosis and correction of anemia and implementation of alternative methods of blood volume management.

The Hema e-Chart prospectively collected data on febrile events (FEs) in hematological malignancy patients (HMs). The aim of the study was to assess the number, causes and outcome of HM-related FEs. Data were collected in a computerized registry that systematically approached the study and the evolution of FEs developing in a cohort of adult HMs who were admitted to 19 hematology departments in Italy from March 2007 to December 2008. A total of 869 FEs in 3,197 patients with newly diagnosed HMs were recorded. Fever of unidentified origin (FUO) was observed in 386 cases (44.4%). The other causes of FE were identified as noninfectious in 48 cases (5.5%) and infectious in 435 cases (50.1%). Bacteria were the most common cause of infectious FEs (301 cases), followed by fungi (95 cases), and viruses (7 cases). Mixed agents were isolated in 32 episodes. The attributable mortality rate was 6.7% (58 FEs). No deaths were observed in viral infection or in the noninfectious groups, while 25 deaths were due to FUO, 16 to bacterial infections, 14 to fungal infections, and three to mixed infections. The Hema e-Chart provided a complete system for the epidemiological study of infectious complications in HMs.
