Background: Reduction of blood transfusion in cardiac surgery is an important target. The aim of this study was to investigate the cost-effectiveness of the use of CryoSeal®, an allogeneic single-donor fibrin sealant, in patients undergoing coronary artery bypass grafting (CABG)., Methods: This randomized clinical study involved seven cardiac surgery centres in the Netherlands. Patients undergoing elective isolated CABG with the use of at least one internal thoracic artery (ITA) graft were assigned randomly to receive either CryoSeal® (5 ml per ITA bed) or no CryoSeal®. Primary efficacy endpoints were units of transfused red blood cells, fresh frozen plasma and platelet concentrates, and duration of intensive care unit stay. Secondary efficacy endpoints were 48-h blood loss, reoperation for bleeding, mediastinitis, 30-day mortality and duration of hospital stay., Results: Between March 2009 and January 2012, 1445 patients were randomized. The intention-to-treat (ITT) population comprised 1436 patients; the per-protocol (PP) population 1292. In both the ITT and the PP analysis, no significant difference between the treatment groups was observed for any of the primary and secondary efficacy endpoints. In addition, no significant difference between the groups was seen in the proportion of transfused patients. Estimated CryoSeal® costs were €822 (95 per cent c.i. €808 to €836) per patient, which translated to €72,000 per avoided transfusion (unbounded 95 per cent c.i.)., Conclusion: The use of the fibrin sealant CryoSeal® did not result in health benefits. Combined with the high cost per avoided transfusion, this study does not support the implementation of routine CryoSeal® use in elective isolated CABG., Registration Number: NTR1386 ( http://www.trialregister.nl)., (© 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.)

Background: Perioperative red blood cell (RBC) transfusion may be associated with a poor prognosis in cancer surgery. Allogeneic leucocytes are assumed to play a causal role. This study evaluated the long-term effect of transfusion with leucocyte-depleted (LD) blood in patients with gastrointestinal cancer., Methods: The Transfusion Associated Complications = Transfusion Induced Complications? (TACTIC) study is a multicentre randomized controlled trial evaluating the short-term benefits of LD versus non-LD RBC transfusions. The present study evaluated 5-year survival and cancer recurrence among 512 patients with gastrointestinal cancer included in the TACTIC study., Results: Some 89.2 per cent of patients had a primary tumour and 79.7 per cent underwent surgery with curative intent; 243 patients received perioperative RBC transfusion (median 3 units). The 5-year overall survival rate of patients with any type of gastrointestinal cancer was 50.8 per cent in the LD group and 45.8 per cent in the non-LD group (P = 0.191). Corresponding 5-year disease-free survival rates were 60.0 and 56.6 per cent (P = 0.482), and recurrence rates 32.9 and 34.3 per cent (P = 0.864)., Conclusion: Leucocyte depletion is not associated with better long-term survival and lower recurrence rates in patients with gastrointestinal cancer., (Copyright 2009 British Journal of Surgery Society Ltd.)
