- Effect of postoperative goal-directed therapy in cancer patients undergoing high-risk surgery: a randomized clinical trial and meta-analysis(2018) GERENT, Aline Rejane Muller; ALMEIDA, Juliano Pinheiro; FOMINSKIY, Evgeny; LANDONI, Giovanni; OLIVEIRA, Gisele Queiroz de; RIZK, Stephanie Itala; FUKUSHIMA, Julia Tizue; SIMOES, Claudia Marques; RIBEIRO JR., Ulysses; PARK, Clarice Lee; NAKAMURA, Rosana Ely; FRANCO, Rafael Alves; CANDIDO, Patricia Ines; TAVARES, Cintia Rosa; CAMARA, Ligia; FERREIRA, Graziela dos Santos Rocha; ALMEIDA, Elisangela Pinto Marinho de; KALIL FILHO, Roberto; GALAS, Filomena Regina Barbosa Gomes; HAJJAR, Ludhmila AbrahaoBackground: Perioperative goal-directed hemodynamic therapy (GDHT) has been advocated in high-risk patients undergoing noncardiac surgery to reduce postoperative morbidity and mortality. We hypothesized that using cardiac index (CI)-guided GDHT in the postoperative period for patients undergoing high-risk surgery for cancer treatment would reduce 30-day mortality and postoperative complications. Methods: A randomized, parallel-group, superiority trial was performed in a tertiary oncology hospital. All adult patients undergoing high-risk cancer surgery who required intensive care unit admission were randomly allocated to a CI-guided GDHT group or to a usual care group. In the GDHT group, postoperative therapy aimed at CI >= 2.5 L/min/m(2) using fluids, inotropes and red blood cells during the first 8 postoperative hours. The primary outcome was a composite endpoint of 30-day all-cause mortality and severe postoperative complications during the hospital stay. A meta-analysis was also conducted including all randomized trials of postoperative GDHT published from 1966 to May 2017. Results: A total of 128 patients (64 in each group) were randomized. The primary outcome occurred in 34 patients of the GDHT group and in 28 patients of the usual care group (53.1% vs 43.8%, absolute difference 9.4 (95% CI, -7.8 to 25.8); p = 0.3). During the 8-h intervention period more patients in the GDHT group received dobutamine when compared to the usual care group (55% vs 16%, p < 0.001). A meta-analysis of nine randomized trials showed no differences in postoperative mortality (risk ratio 0.85, 95% CI 0.59-1.23; p = 0.4; p for heterogeneity = 0.7; I-2 = 0%) and in the overall complications rate (risk ratio 0.88, 95% CI 0.71-1.08; p = 0.2; p for heterogeneity = 0.07; I-2 = 48%), but a reduced hospital length of stay in the GDHT group (mean difference (MD) - 1.6; 95% CI - 2.75 to -0.46; p = 0.006; p for heterogeneity = 0.002; I-2 = 74%). Conclusions: CI-guided hemodynamic therapy in the first 8 postoperative hours does not reduce 30-day mortality and severe complications during hospital stay when compared to usual care in cancer patients undergoing high-risk surgery.
- Liberal Versus Restrictive Transfusion Strategy in Critically Ill Oncologic Patients: The Transfusion Requirements in Critically Ill Oncologic Patients Randomized Controlled Trial(2017) BERGAMIN, Fabricio S.; ALMEIDA, Juliano P.; LANDONI, Giovanni; GALAS, Filomena R. B. G.; FUKUSHIMA, Julia T.; FOMINSKIY, Evgeny; PARK, Clarice H. L.; OSAWA, Eduardo A.; DIZ, Maria P. E.; OLIVEIRA, Gisele Q.; FRANCO, Rafael A.; NAKAMURA, Rosana E.; ALMEIDA, Elisangela M.; ABDALA, Edson; FREIRE, Maristela P.; FILHO, Roberto K.; AULER JR., Jose Otavio C.; HAJJAR, Ludhmila A.Objective: To assess whether a restrictive strategy of RBC transfusion reduces 28-day mortality when compared with a liberal strategy in cancer patients with septic shock. Design: Single center, randomized, double-blind controlled trial. Setting: Teaching hospital. Patients: Adult cancer patients with septic shock in the first 6 hours of ICU admission. Interventions: Patients were randomized to the liberal (hemoglobin threshold, < 9 g/dL) or to the restrictive strategy (hemoglobin threshold, < 7 g/dL) of RBC transfusion during ICU stay. Measurements and Main Results: Patients were randomized to the liberal (n = 149) or to the restrictive transfusion strategy (n = 151) group. Patients in the liberal group received more RBC units than patients in the restrictive group (1 [0-3] vs 0 [0-2] unit; p<0.001). At 28 days after randomization, mortality rate in the liberal group (primary endpoint of the study) was 45% (67 patients) versus 56% (84 patients) in the restrictive group (hazard ratio, 0.74; 95% CI, 0.53-1.04; p = 0.08) with no differences in ICU and hospital length of stay. At 90 days after randomization, mortality rate in the liberal group was lower (59% vs 70%) than in the restrictive group (hazard ratio, 0.72; 95% CI, 0.53-0.97; p = 0.03). Conclusions: We observed a survival trend favoring a liberal transfusion strategy in patients with septic shock when compared with the restrictive strategy. These results went in the opposite direction of the a priori hypothesis and of other trials in the field and need to be confirmed.
- Transfusion Requirements in Surgical Oncology Patients A Prospective, Randomized Controlled Trial(2015) ALMEIDA, Juliano Pinheiro de; VINCENT, Jean-Louis; GALAS, Filomena Regina Barbosa Gomes; ALMEIDA, Elisangela Pinto Marinho de; FUKUSHIMA, Julia T.; OSAWA, Eduardo A.; BERGAMIN, Fabricio; PARK, Clarice Lee; NAKAMURA, Rosana Ely; FONSECA, Silvia M.

Methods: In a randomized, controlled, parallel-group, double-blind (patients and outcome assessors) superiority trial in the intensive care unit of a tertiary oncology hospital, the authors evaluated whether a restrictive strategy of erythrocyte transfusion (transfusion when hemoglobin concentration <7 g/dl) was superior to a liberal one (transfusion when hemoglobin concentration <9 g/dl) for reducing mortality and severe clinical complications among patients having major cancer surgery. All adult patients with cancer having major abdominal surgery who required postoperative intensive care were included and randomly allocated to treatment with the liberal or the restrictive erythrocyte transfusion strategy. The primary outcome was a composite endpoint of mortality and morbidity. Results: A total of 198 patients were included as follows: 101 in the restrictive group and 97 in the liberal group. The primary composite endpoint occurred in 19.6% (95% CI, 12.9 to 28.6%) of patients in the liberal-strategy group and in 35.6% (27.0 to 45.4%) of patients in the restrictive-strategy group (P = 0.012). Compared with the restrictive strategy, the liberal transfusion strategy was associated with an absolute risk reduction for the composite outcome of 16% (3.8 to 28.2%) and a number needed to treat of 6.2 (3.5 to 26.5). Conclusion: A liberal erythrocyte transfusion strategy with a hemoglobin trigger of 9 g/dl was associated with fewer major postoperative complications in patients having major cancer surgery compared with a restrictive strategy.
