Is breast cancer surgery safely performed in patients receiving antithrombotic therapy?

ABSTRACT: Aim:The aim of the study was to assess the safety of surgery for breast cancer in patients with antithrombotic therapy (ATT), including antiplatelet therapy (APT) and anticoagulation therapy (ACT) for thromboembolic risks. Methods:One hundred ninety-three consecutive patients receiving breast surgery for breast cancer at our institution between 2010 and 2015 were retrospectively reviewed. Among them, ATT was regularly used in 50 patients (25.9%). Our perioperative management included maintenance of preoperative aspirin monotherapy for APT and bridging heparin for ACT in patients at high thromboembolic risks and early postoperative reinstitution in all ATT cases. The outcome variables of patients with ATT (ATT group) were compared to those of patients without ATT (non-ATT group), and the significant risk factors for postoperative complications were determined by multivariate analysis. Results:This series included 127 mastectomy and 66 breast-conserving surgery. ATT group showed significantly high frequency of history of cerebral infarction and percutaneous coronary intervention (PCI). In the ATT group, 32 patients (16.6%) were categorized as high risk for thromboembolism, but there was neither thromboembolic event nor perioperative death in the whole cohort. Surgical blood loss and rates of intraoperative transfusion were identical between the groups. Whereas overall postoperative bleeding complication was more frequently observed in the ATT group compared to the non-ATT group (12.0% vs. 3.5%, p=0.360) in univariate analyses, multivariate analysis showed that neither ATT nor preoperative aspirin continuation affected postoperative bleeding complications. Conclusion:Even in patients undergoing ATT, surgery for breast cancer is safely performed without any increase in blood loss or postoperative bleeding, and no thromboembolism was experienced in the series. Our perioperative management of ATT patients is valid during breast surgery, although this patient population is still challenging and should be rigorously managed.

Project description:Background and purposeThe prevalence of chronic renal disease (CRD) is rising worldwide. Patients with CRD are more likely to have associated medical problems and are at greater risk of postoperative morbidity and mortality. We evaluated patient characteristics and risk of early revision, surgical site infection (SSI), thromboembolic events, mortality, and re-admission of patients with CRD undergoing total knee arthroplasty (TKA). We hypothesized that this patient population would have higher rates of complications.Patients and methodsWe conducted a retrospective analysis of data that had been prospectively collected by a Total Joint Replacement Registry. All primary TKAs performed from 2005 through 2010 were included. 41,852 primary TKA cases were evaluated, of which 2,686 (6.4%) TKA procedures had been performed in CRD patients. Patient characteristics, comorbidities, and general health status were evaluated. Cox proportional hazard regressions and logistic regressions were used to evaluate the association of CRD with outcomes while adjusting for confounding variables. Results - The mean age of the CRD cohort was 67 years and approximately two-thirds of the patients were female. The median follow-up time was 2.1 years. Compared to TKA patients without CRD the CRD patients were older, had poorer general health, and had a higher prevalence of comorbidities. They had a higher incidence of deep SSI (0.9% vs. 0.7%), superficial SSI (0.5% vs. 0.3%), deep vein thrombosis (0.6% vs. 0.4%), any-time mortality (4.7% vs. 2.4%), 90-day mortality (0.4% vs. 0.2%), and 90-day re-admission (10% vs. 6.0%) than patients without CRD. However, after adjustment for confounding variables, CRD patients were at 1.9 times (95% CI: 1.1-3.5) increased risk of superficial SSI, 1.3 times (CI: 1.1-1.6) increased risk of re-admission within 90 days, and 1.5 times (CI: 1.2-1.8) increased risk of mortality at any point after the procedure. The risks of all other complications were not statistically significantly different in patients with CRD compared to patients without CRD.ConclusionsCRD patients undergoing TKA have more comorbidities and a higher risk for superficial SSI, 90-day re-admission, and any-time mortality.

Project description:BACKGROUND: The use of antithrombotic agents and falls are independently associated with an increased risk of hemorrhagic injury. However, few studies have delineated the risk of fall-related hemorrhagic complications in persons who are taking antithrombotic therapy. The objective of this study was to compare the rates of fall-related hemorrhagic injury in hospital in-patients who are taking and not taking antithrombotic therapy. METHODS: A 4-year retrospective chart review of consecutive patients who fell during admission to a 500-bed tertiary-care teaching hospital was conducted. Major hemorrhagic injuries including subdural hematomas and major bleeding/cuts, patients' use of antithrombotic medication (warfarin, aspirin, clopidogrel and heparin) and their anticoagulation status at the time of their fall were recorded. RESULTS: A total of 2635 falls in 1861 patients were reviewed. Approximately 10% of falls caused major hemorrhagic injury. One fall resulted in a subdural hematoma. Persons taking warfarin were less likely to suffer a fall-related major hemorrhagic injury compared with persons not taking antithrombotic therapy (warfarin, 6%; no therapy, 11%; p = 0.01). Logistic regression showed that fall-related major hemorrhagic injury was associated with female gender (odds ratio 1.6; 95% CI 1.3, 2.1), use of aspirin (odds ratio 1.4; 95% CI 1.1, 1.8) and use of clopidogrel (odds ratio 2.2; 95% CI 1.1, 4.8), but not with the use of warfarin or heparin, or the intensity of anticoagulation. CONCLUSIONS: In this study, compared with persons taking no antithrombotic therapy, those taking warfarin had lower rates of fall-related hemorrhagic injuries. The absolute rate of the development of fall-related intracranial hemorrhagic injury such as subdural hematomas was low, even in persons taking warfarin. These counter-intuitive results may be due to selection bias, and suggest that physicians are very conservative in selecting patients for warfarin therapy, choosing only those who are sufficiently healthy to be at much lower than average risk of suffering fall-related hemorrhagic injuries. This phenomenon may lead to physicians overestimating the potential for fall-related major hemorrhagic injury in persons taking antithrombotic therapy, with the possible denial of warfarin therapy to many of those who would benefit. This perception may contribute to the care gap between the number of patients who would theoretically derive overall benefit from warfarin therapy and those who are actually receiving it.
