The Associations between Perioperative Blood Transfusion and Long-Term Outcomes after Stomach Cancer Surgery.

ABSTRACT: Whether perioperative packed red blood cell (pRBC) transfusion is associated with inferior long-term outcomes after stomach cancer surgery remains controversial. This research used a retrospective cohort study. Patients with stage I~III stomach cancer undergoing tumor resection were collected at a tertiary medical center. Patient characteristics, surgical features and pathologic findings were gathered from an electronic medical chart review. The associations of perioperative pRBC transfusion with postoperative disease-free and overall survivals were evaluated using Cox regression analysis with an inverse probability of treatment weighting (IPTW). Restricted cubic spline functions were employed to characterize dose-response relationships between the amount of transfusion and cancer outcomes after surgery. Among the 569 patients, 160 (28.1%) received perioperative pRBC transfusion. Perioperative transfusion was associated with worse disease-free survival (IPTW adjusted HR: 1.42, 95% CI: 1.18-1.71, p < 0.001) and overall survival (IPTW adjusted HR: 1.27, 95% CI: 1.05-1.55, p = 0.014). A non-linear dose-response relationship was noted between the amount of transfusions and worse disease-free or overall survival. Perioperative pRBC transfusion was associated with worse disease-free and overall survival after stomach cancer surgery, and strategies aiming to minimize perioperative transfusion exposure should be further considered to reduce the potential risk.

Project description:BackgroundPerioperative anemia and transfusion are intertwined with each other, and both have adverse impacts on the survival of colorectal cancer (CRC) patients. But the treatment of anemia still relies on transfusion in several countries, which leads us to question the effects of anemia tolerance and transfusion on the long-term outcomes of CRC patients. We investigated the combined effect of preoperative anemia and postoperative anemia and of preoperative anemia and blood transfusion, which imposes a greater risk to survival, to compare the effects of anemia tolerance and transfusion on overall survival (OS) and disease-free survival (DFS) in patients undergoing CRC surgery.MethodsA retrospective propensity-score-matched analysis included patients with CRC undergoing elective surgery between January 1, 2008, and December 31, 2014. After propensity-score matching, Kaplan-Meier survival analysis and univariable and multivariable Cox proportional hazards models were used to study the prognostic factors for survivals. In univariate and multivariate Cox regression analysis, two novel models were built.ResultsOf the 8,121 patients with CRC, 1,975 (24.3%) and 6,146 (75.7%) patients presented with and without preoperative anemia, respectively. After matching, 1,690 patients remained in each group. In the preoperative anemia and postoperative anemia model, preoperative anemia and postoperative anemia was independent risk factor for OS (HR, 1.202; 95% CI, 1.043-1.385; P=0.011) and DFS (HR, 1.210; 95% CI, 1.050-1.395; P=0.008). In the preoperative anemia and transfusion model, preoperative anemia and transfused was the most dangerous independent prognostic factor for OS (HR, 1.791; 95% CI, 1.339-2.397; P<0.001) and DFS (HR, 1.857; 95% CI, 1.389-2.483; P<0.001). In patients with preoperative anemia, the OS and DFS of patients with transfusion were worse than those of patients without transfusion (P=0.026 in OS; P=0.037 in DFS).ConclusionsPreoperative anemia and blood transfusion imposed a greater risk to OS and DFS in patients undergoing CRC surgery, indicating that the harm associated with blood transfusion was greater than that associated with postoperative anemia. These findings should encourage clinicians to be vigilant for the timely prevention and treatment of anemia, by appropriately promoting toleration of anemia and restricting the use of blood transfusion in patients with CRC.

Project description:ImportanceThere is known variation in perioperative mortality rates across hospitals. However, the extent to which this variation is associated with hospital-level differences in longer-term survival has not been characterized.ObjectiveTo evaluate the association between hospital perioperative quality and long-term survival after noncardiac surgery.Design, setting, and participantsThis national cohort study included 654 093 US veterans who underwent noncardiac surgery at 98 hospitals using data from the Veterans Affairs Surgical Quality Improvement Program from January 1, 2011, to December 31, 2016. Data were analyzed between January 1 and November 1, 2021.ExposuresHospitals were stratified separately into quintiles of reliability-adjusted failure to rescue (FTR) and mortality rates. Patients were further categorized as having a complicated or uncomplicated postoperative course.Main outcomes and measuresThe association between hospital FTR or mortality performance quintile (with quintile 1 representing low FTR or mortality and quintile 5 representing very high FTR or mortality) and overall risk of death was evaluated separately using multivariable shared frailty modeling among patients with a complicated and uncomplicated postoperative course.ResultsFor the overall cohort of 654 093 patients, the mean (SD) age was 61.1 (13.2) years; 597 515 (91.4%) were men and 56 578 (8.7%) were women; 111 077 (17.0%) were Black, 5953 (0.9%) were Native American, 467 969 (71.5%) were White, 42 219 (6.5%) were missing a racial category, and 26 875 (4.1%) were of another race; and 37 538 (5.7%) were Hispanic. Hospital-level 5-year survival for patients with a complicated course ranged from 42.7% (95% CI, 38.1%-46.9%) to 82.4% (95% CI, 59.0%-93.2%) and from 76.2% (95% CI, 74.4%-78.0%) to 95.2% (95% CI, 92.5%-97.7%) for patients with an uncomplicated course. Overall, 47 (48.0%) and 83 (84.7%) of 98 hospitals were either in the same or within 1 performance quintile for FTR and mortality, respectively. Among patients who had a postoperative complication, there was a dose-dependent association between care at hospitals with higher FTR rates and risk of death (compared with quintile 1: quintile 2 hazard ratio [HR], 1.05 [95% CI, 0.99-1.12]; quintile 3 HR, 1.17 [95% CI, 1.10-1.26]; quintile 4 HR, 1.30 [95% CI, 1.22-1.38]; and quintile 5 HR, 1.34 [95% CI, 1.22-1.43]). Similarly, increasing hospital FTR rates were associated with increasing risk of death among patients without complications (compared with quintile 1: quintile 2 HR, 1.07 [95% CI, 1.01-1.14]; quintile 3 HR, 1.10 [95% CI, 1.04-1.16]; quintile 4 HR, 1.15 [95% CI, 1.09-1.21]; and quintile 5 HR, 1.10 [95% CI, 1.05-1.19]). These findings were similar across hospital mortality quintiles for patients with complicated and uncomplicated courses.Conclusions and relevanceThe findings of this cohort study suggest that the structures, processes, and systems of care that underlie the association between FTR and worse short-term outcomes may also have an influence on long-term survival through a pathway other than rescue from complications. A better understanding of these differences could lead to strategies that address variation in both perioperative and longer-term outcomes.

Project description:BackgroundPreoperative anemia is a well-established risk factor for short-term mortality in patients undergoing noncardiac surgery, but appropriate thresholds for transfusion remain uncertain. The objective of this study was to determine long-term outcomes associated with anemia, hemorrhage, and red blood cell transfusion in patients undergoing noncardiac surgery.MethodsWe performed a long-term follow-up study of consecutive subjects undergoing hip, knee, and spine surgery between November 1, 2008 and December 31, 2009. Clinical data were obtained from administrative and laboratory databases, and retrospective record review. Preoperative anemia was defined as baseline hemoglobin < 13 g/dL for men and < 12 g/dL for women. Hemorrhage was defined by International Classification of Diseases, Ninth Revision coding. Data on long-term survival were collected from the Social Security Death Index database. Logistic regression models were used to identify factors associated with long-term mortality.ResultsThere were 3050 subjects who underwent orthopedic surgery. Preoperative anemia was present in 17.6% (537) of subjects, hemorrhage occurred in 33 (1%), and 766 (25%) received at least one red blood cell transfusion. Over 9015 patient-years of follow-up, 111 deaths occurred. Anemia (hazard ratio [HR] 3.91; confidence interval [CI], 2.49-6.15) and hemorrhage (HR 5.28; 95% CI, 2.20-12.67) were independently associated with long-term mortality after multivariable adjustment. Red blood cell transfusion during the surgical hospitalization was associated with long-term mortality (HR 3.96; 95% CI, 2.47-6.34), which was attenuated by severity of anemia (no anemia [HR 4.39], mild anemia [HR 2.27], and moderate/severe anemia [HR 0.81]; P for trend .0015).ConclusionsPreoperative anemia, perioperative bleeding, and red blood cell transfusion are associated with increased mortality at long-term follow-up after noncardiac surgery. Strategies to minimize anemia and bleeding should be considered for all patients, and restrictive transfusion strategies may be advisable. Further investigation into mechanisms of these adverse events is warranted.

Project description:BackgroundThis study investigated the associations between transfusion of different types of red blood cell (RBC) preparations and kidney allograft outcomes after kidney transplantation (KT) over a 16-year period in Korea using a nationwide population-based cohort.MethodsWe investigated the reported use of RBCs during hospitalization for KT surgery, rejection, and graft failure status using nationwide data from the National Health Information Database (2002-2017). The associations between the type of perioperative RBC product and transplant outcomes were evaluated among four predefined groups: no RBC transfusion, filtered RBCs, washed RBCs, and packed RBCs (pRBCs).ResultsA total of 17,754 KT patients was included, among which 8,530 (48.0%) received some type of RBC transfusion. Of the patients who received RBC transfusion, 74.9%, 19.7%, and 5.4% received filtered RBCs, pRBCs, or washed RBCs, respectively. Regardless of the type of RBC products, the proportions of acute rejection and graft failure was significantly greater in patients receiving transfusion (P < 0.001). Cox proportional hazards regression analyses showed that the filtered RBC and pRBC groups were significantly associated with both rejection and graft failure. The washed RBC group also had hazard ratios greater than 1.0 for rejection and graft failure, but the association was not significant. Rejection-free survival of the pRBC group was significantly lower than that of the other groups (P < 0.001, log-rank test), and graft survival for the no RBC transfusion group was significantly greater than in the other groups (P < 0.001, log-rank test).ConclusionPerioperative RBC transfusion was associated with poor graft outcomes. Notably, transfusion of pRBCs significantly increased transplant rejection. Therefore, careful consideration of indications for RBC transfusion and selection of the appropriate type of RBCs is necessary, especially for patients at high risk of rejection or graft failure.

Project description:IntroductionWe aimed to evaluate the neuroimaging findings and long-term neurodevelopmental outcomes of fetuses and children following intrauterine blood transfusion (IUT) for parvo B19 infection-induced anemia compared to those with RBC alloimmunization.MethodsWe conducted a retrospective cohort study including women who underwent an IUT due to fetal anemia between 2006 and 2019 in a tertiary, university-affiliated medical center. The cohort was divided into two groups: a study group - fetuses affected by congenital parvo B19 infection; and a control group - fetuses affected by RBC alloimmunization. Retrospective data such as antenatal sonographic evaluations, fetal brain MRI results, and short-term fetal and neonatal outcomes were collected. All children underwent a neurodevelopmental evaluation after birth using a Vineland questionnaire. Primary outcome was defined as the presence or absence of neurodevelopmental delay. Secondary outcome was defined as the presence of abnormal fetal neuroimaging findings such as cerebellar hypoplasia, polymicrogyria, intracranial hemorrhage, or severe ventriculomegaly.ResultsOverall, 71 fetuses requiring at least one IUT were included in the study. Of these, 18 were affected by parvo B19 infection and 53 by RBC alloimmunization with various associated antibodies. Fetuses in the parvo B19 group presented at an earlier gestational age (22.91 ± 3.36 weeks vs. 27.37 ± 4.67 weeks, p = 0.002) and were more affected by hydrops (93.33% vs. 16.98%, p < 0.001). Three fetuses out of the 18 (16.67%) fetuses in the parvo B19 group died in utero following the IUT. Abnormal neuroimaging findings were detected in 4/15 (26.7%) of the parvo B19 survivors versus 2/53 (3.8%) of fetuses affected by RBC alloimmunization (p = 0.005). There was no difference in long-term neurodevelopmental delay rates between the children in the study and control groups, as assessed at the average age of 3.65 and 6.53 years, accordingly.ConclusionFetal anemia due to parvo B19, treated with IUT, might be associated with increased rates of abnormal neurosonographic findings. The correlation between those findings and long-term adverse neurodevelopmental outcomes requires further investigation.
