ABSTRACT

(1) Background: Cancer treatment, including chemotherapy, endocrine therapy, targeted therapy and radiotherapy, has been identified as an important independent risk factor for venous thromboembolism in cancer patients. The aim of the study was to evaluate the effect of adjuvant therapy on the coagulation and fibrinolysis components in invasive breast cancer. (2) Methods: Tissue factor pathway inhibitor (TFPI), tissue factor (TF), tissue plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1) antigen (concentration) and TFPI and TF activities were examined in the blood samples of 60 breast cancer patients treated by adjuvant chemotherapy, endocrine therapy, radiotherapy and immunotherapy. Blood samples were taken 24 h before primary surgery and 8 months after tumour removal surgery. (3) Results: Adjuvant therapy administrated to breast cancer patients significantly increased the concentration of plasma TF, the PAI-1 antigen and also the activity of TFPI and TF, but significantly decreased the level of the t-PA antigen. Combined chemotherapy and endocrine therapy, but not monotherapy, has an important effect on haemostatic biomarker levels. (4) Conclusions: Breast cancer patients receiving adjuvant therapy have an elevated risk of developing a hypercoagulability and hypofibrinolysis state leading to venous thromboembolism.

Evaluation of Patient Characteristics Linked to Major Bleeding Events in Patients Prescribed Direct Oral Anticoagulants

Clin Appl Thromb Hemost. 2023 Jan-Dec;29:10760296231172765. doi: 10.1177/10760296231172765.

ABSTRACT

INTRODUCTION: Direct oral anticoagulants (DOACs) demonstrated similar efficacy and lower risk of intracranial hemorrhage than warfarin in patients with atrial fibrillation and venous thromboembolism. Given the lack of data identifying risk factors in patients who bled while on a DOAC, we sought to investigate these characteristics.

MATERIALS AND METHODS: This retrospective chart review was approved by the Mass General Brigham Institutional Review Board and assessed patients who experienced bleeding events while on DOAC therapy from 6/1/2015 to 7/1/2020. Patient characteristics were evaluated, including age, sex, body mass index (BMI), renal function, concomitant therapies, and baseline comorbidities.

RESULTS: Eighty-seven patients were included for analysis, with a median age of 75.8 years. Most patients were female (51.7%) and 24 (27.6%) had a BMI >30. At time-of-event, 21 patients (24.1%) had acute kidney injury. Thirty-three patients (37.9%) were on concomitant antiplatelet therapy (APT), with 31 (35.6%) on single APT and 2 on dual APT. Pertinent comorbidities included hypertension (74.7%), ischemic cerebrovascular accident (28.7%), thyroid abnormality (23.0%), active cancer (14.9%), and anemia (13.8%). Eleven patients (12.6%) had a prior bleeding event. Most patients were on apixaban (69.0%) for the indication of stroke prevention in nonvalvular atrial fibrillation/flutter (72.4%). FDA-approved dosing was used in most patients (92.0%), and all deviations reflected underdosing. Most bleeding events were defined as major (95.4%), occurred at a critical organ site (72.4%), and developed spontaneously (58.6%).

CONCLUSIONS: These data provide insight into characteristics of patients who experience bleeding events while on DOAC therapy. Understanding these potential risk factors may optimize the safe use of these agents.

Spray Cryotherapy for Benign Large Airway Stenosis: A Multicenter Retrospective Cohort Study of Safety and Practice Patterns

J Bronchology Interv Pulmonol. 2023 May 29. doi: 10.1097/LBR.0000000000000930. Online ahead of print.

ABSTRACT

BACKGROUND: Benign airway stenosis (BAS) represents a significant burden on patients, providers, and healthcare systems. Spray cryotherapy (SCT) has been proposed as an adjunctive treatment to reduce BAS recurrence. We sought to examine safety and practice variations of the latest SCT system when used for BAS.

METHODS: We conducted a retrospective multicenter cohort study in seven academic institutions within the Interventional Pulmonary Outcomes Group. All patients who underwent at least one SCT session with a diagnosis of BAS at the time of procedure at these institutions were included. Demographics, procedure characteristics, and adverse events were captured through each center's procedural database and electronic health record.

RESULTS: A total of 102 patients underwent 165 procedures involving SCT from 2013 to 2022. The most frequent etiology of BAS was iatrogenic (n = 36, 35%). In most cases, SCT was used prior to other standard BAS interventions (n = 125; 75%). The most frequent SCT actuation time per cycle was five seconds. Pneumothorax complicated four procedures, requiring tube thoracostomy in two. Significant post-SCT hypoxemia was noted in one case, with recovery by case conclusion and no long-term effects. There were no instances of air embolism, hemodynamic compromise, or procedural or in-hospital mortality.

CONCLUSION: SCT as an adjunctive treatment for BAS was associated with a low rate of complications in this retrospective multicenter cohort study. SCT-related procedural aspects varied widely in examined cases, including actuation duration, number of actuations, and timing of actuations relative to other interventions.

Safety Profile and Effectiveness of Rivaroxaban for Patients With Venous Thromboembolism in Japan　- Results From Post-Marketing Surveillance (XASSENT)

Circ J. 2023 May 27. doi: 10.1253/circj.CJ-23-0104. Online ahead of print.

ABSTRACT

BACKGROUND: The incidence of venous thromboembolism (VTE; pulmonary embolism [PE] and/or deep vein thrombosis [DVT]) in Japan is increasing, but relatively small numbers of patients from Japan have been included in studies investigating rivaroxaban (a direct factor Xa inhibitor) for the treatment of VTE and preventing its recurrence.Methods and Results: An open-label, prospective, observational study (XASSENT [NCT02558465]) investigated the safety profile and effectiveness of rivaroxaban for ≤2 years in the treatment of VTE and prevention of its recurrence in Japanese clinical practice. Primary outcomes were major bleeding and symptomatic recurrent VTE. Statistical analyses were exploratory and descriptive. Overall, 2,540 patients were enrolled (safety analysis population [SAP], n=2,387; effectiveness analysis population [EAP], n=2,386). In the SAP, >80% of patients received the approved rivaroxaban dose, the mean (standard deviation) age was 66.6 (15.0) years, ≈74% were >50 kg, and 43% had a creatinine clearance ≥80 mL/min. PE+DVT, PE only, and DVT only were reported in 42%, 8%, and 50% of patients, respectively, and active cancer in 17% of patients. Major bleeding was reported in 69 patients (2.89%; 3.60%/patient-year; SAP) and symptomatic PE/DVT recurrence in 26 patients (1.09%; 1.36%/patient-year; EAP) during the treatment period.

CONCLUSIONS: XASSENT provided information on the expected proportions of bleeding and VTE recurrence during rivaroxaban treatment in Japanese clinical practice; no new concerns of safety or effectiveness were found.

Preoperative Venous Thromboembolism Screening and Postoperative Selective Anticoagulant Therapy Effectively Prevents Postoperative Symptomatic Venous Thromboembolism in Gynecological Malignancies: A 15-Year, Single-Center Study

Clin Appl Thromb Hemost. 2023 Jan-Dec;29:10760296231178300. doi: 10.1177/10760296231178300.

ABSTRACT

The aim of this study was to determine which type of prophylaxis was effective for postoperative symptomatic venous thromboembolism (VTE) in patients with gynecological malignancies. A total of 1756 consecutive patients undergoing laparotomy as first-line treatment were included. In Period 1 (2004-2009), low-molecular weight heparin (LMWH) was not available for postoperative VTE prophylaxis, but available in after Period 2 (2009-2013). In Period 3 (2013-2020), patients with pretreatment VTE could switch from LMWH to direct oral anticoagulant (DOAC) as of 2015. Preoperative VTE was screened by measuring D-dimer, followed by venous ultrasound imaging, and computed tomography and/or perfusion lung scintigraphy. Postoperative symptomatic VTE occurred with an incidence of 2.8% by the measures without prophylactic LMWH administration in Period 1. The incidence of postoperative symptomatic VTE was 0.6% in Period 2 and 0.3% in Period 3, being significantly reduced compared with Period 1 (P < .01 and < .0001). The incidences were not significantly different between Periods 2 and 3, but no patient switching to DOAC in Period 3 (n = 79) developed symptomatic VTE. Our preoperative VTE screening and postoperative selective LMWH administration were significantly preventive against postoperative symptomatic VTE.

Cardiac Metastatic Tumors: Current Knowledge

Am J Clin Oncol. 2023 May 26. doi: 10.1097/COC.0000000000001013. Online ahead of print.

ABSTRACT

Cardiac tumors are a heterogeneous group of pathologic masses of the heart that contain primary tumors-benign or malignant, and secondary tumors. Metastases are significantly more frequent, mostly originating from lung, breast, gastrointestinal tract, or ovary carcinomas. Secondary cardiac tumors may be asymptomatic or may cause cardiovascular, systemic, or embolic symptoms. The study is a summary of the available knowledge on cancerous metastatic lesions of the heart. Pleural mesothelioma (48.4%), adenocarcinoma (19.5%), or squamous cell carcinoma (18.2%) of lung, breast carcinoma (15.5%), ovarian carcinoma (10.3%), and bronchoalveolar carcinomas (9.8%) are cited as the most common origin of secondary heart tumors. Masses can spread by direct tumor invasion, by lymphatic vessels, veins, or arteries. Patients with cancer and nonspecific cardiovascular symptoms should be particularly vigilant, and the possibility of metastasis in an unusual location such as the myocardium should be considered in the diagnosis. Diagnostic methods include echocardiography, cardiac magnetic resonance, computed tomography, positron emission tomography, and histologic evaluation. Treatment of choice is managing primary carcinoma, due to the poor outcomes of surgical methods.
