The clinical features and related factors of PICC-related upper extremity asymptomatic venous thrombosis in cancer patients: A prospective study

Peripherally inserted central venous catheter (PICC) is the main venous access for cancer patients when they receive chemotherapy and nutritional support, but PICC-related venous thrombosis has become one of the most common and serious complications. It is very important to further explore the relationship among these features, so that prevent and treat the PICC-related thrombosis. To investigate the clinical features and the related factors of PICC-related upper extremity asymptomatic venous thrombosis in cancer patients, and to provide theoretical basis for the prevention of venous thrombosis. A total of 127 tumor patients with PICC catheterization were selected. Thrombus was detected by color Doppler ultrasound at different times: before catheterization and 24 hours after catheterization, and every week. The study was terminated at the time of thrombosis, and patients who did not develop thrombus were terminated after 6 weeks of follow-up. The clinical characteristics and influencing factors of asymptomatic thrombosis such as vessel diameter, blood flow velocity, thrombosis time, location, and the thrombosis stages were recorded. The incidence of PICC-related upper limbs asymptomatic thrombosis was 48.82% (62/127), and the median time was 3 days. The incidence within 24-hour was 37.1% and within 1 week was 85.49%. A total of 81 venous thrombosis were found in 62 patients with asymptomatic thrombosis, there were 19 (23.5%) venous thrombosis in the deep veins while 62 (...

AbstractPurposeCompared with open thoracotomy, minimally invasive esophagectomy (MIE) methods, such as transhiatal or thoracoscopic esophagectomy, likely have lower morbidity. However, the relationship between intraoperative fluid management and postoperative complications after MIE remains unclear. Thus, we investigated the association of cumulative intraoperative fluid balance and postoperative complications in patients undergoing MIE.MethodsThis single-center retrospective cohort study examined patients undergoing thoracoscopic esophagectomy for esophageal cancer in the prone position. Postoperative complications includ...

AbstractCancer-associated thrombosis (CAT) is a common complication in patients with malignancy. Although direct oral anticoagulants (DOACs) have emerged as a treatment option for CAT, there have not been head-to-head comparisons of these agents. We searched MEDLINE and EMBASE from inception to April 2020 for studies comparing the effect of different long-term anticoagulation strategies for venous thromboembolism (VTE) in patients with cancer. We performed a network meta-analysis comparing the antithrombotic strategies in the selected studies using random-effects model. We identified a total of 20 studies [9 randomized con...

Cancers, Vol. 12, Pages 1354: Incidence, Therapy, and Bleeding Risk—Cancer- Associated Thrombosis in Patients with Glioblastoma Cancers doi: 10.3390/cancers12061354 Authors: Viktoria Muster Thomas Gary Cancer is an independent risk factor for the development of venous thromboembolism (VTE). Glioblastomas are amongst cancer types with the most thrombogenic potential and patients are at a particularly high risk of VTE with an incidence up to 20–30% per year. Currently, major efforts are underway to gain novel insights into risk factors and pathomechanisms to provide a better understanding of develop...

ConclusionsThromboprophylaxis with NOACs is not likely to be cost effective in patients initiating chemotherapy in the Chinese context. The decision about thromboprophylaxis should be tailored based on the survival of patients with cancer, the risks of venous thromboembolism, and major bleeding.

These microparticles are substances released by cells and play a pivotal role in pathophysiology of tumor progression and metastasis, thrombosis, and inflammation. Extracellular vesicles including exosomes and cell-derived microparticles supporting many physiological and disease process...

CONCLUSIONS: Likely due to the high prevalence of DVT, clinical models followed by D-dimer testing fail to rule-out DVT efficiently in cancer patients suspected of DVT. Direct referral for compression ultrasonography appears to be the preferred approach for diagnosis of suspected DVT in cancer patients. PMID: 32433797 [PubMed - as supplied by publisher]

Rossi Valerio De Stefano Lymphoma is listed among the neoplasias with a high risk of venous thromboembolism (VTE). Risk factors for VTE appear to differ from risk factors in solid tumors. We review the literature of the last 20 years for reports identifying these risk factors in cohorts consisting exclusively of lymphoma patients. We selected 25 publications. The most frequent studies were analyses of retrospective single-center cohorts. We also included two reports of pooled analyses of clinical trials, two meta-analyses, two analyses of patient registries, and three analyses of population-based databases. The VTE r...
