ABSTRACT

OBJECTIVE: This systematic review and meta-analysis compares the rate of venous thromboembolism (VTE) in surgical inpatients with pharmacological thromboprophylaxis and additional graduated compression stockings (GCS) versus pharmacological thromboprophylaxis alone.

SUMMARY BACKGROUND DATA: Surgical inpatients have elevated VTE risk; recent studies cast doubt whether GCS confer additional protection against VTE, compared to pharmacological thromboprophylaxis alone.

METHODS: The review followed PRISMA guidelines using a registered protocol (CRD42017062655). The MEDLINE and Embase databases were searched to November 2022. Randomised trials reporting VTE rate after surgical procedures, utilising pharmacological thromboprophylaxis, with or without GCS, were included. The rates of deep venous thrombosis (DVT), pulmonary embolism (PE), VTE-related mortality were pooled via fixed and random effects.

RESULTS: In head-to-head meta-analysis, the risk of DVT for GCS and pharmacological thromboprophylaxis was 0.85 (95% CI 0.54-1.36) versus for pharmacological thromboprophylaxis alone (2 studies, 70 events, 2653 participants). The risk of DVT in pooled trial arms for GCS and pharmacological thromboprophylaxis was 0.54 (95% CI 0.23-1.25) versus pharmacological thromboprophylaxis alone (33 trial arms, 1228 events, 14,108 participants). The risk of PE for GCS and pharmacological prophylaxis versus pharmacological prophylaxis alone was 0.71 (95% CI 0.0-30.0) (27 trial arms, 32 events, 11,472 participants). There were no between-group differences in VTE-related mortality (27 trial arms, 3 events, 12,982 participants).

CONCLUSIONS: Evidence from head-to-head meta-analysis and pooled trial arms demonstrates no additional benefit for GCS in preventing VTE and VTE-related mortality. GCS confer a risk of skin complications and an economic burden; current evidence does not support their use for surgical inpatients.

The Impact of Type 2 Myocardial Infarction in Acute Pancreatitis: Analysis of 1.1 Million Hospitalizations and Review of the Literature

Cureus. 2023 Aug 25;15(8):e44113. doi: 10.7759/cureus.44113. eCollection 2023 Aug.

ABSTRACT

Introduction Acute pancreatitis (AP) is a common inflammatory disorder with acute onset and rapid progression. Studies have reported cardiac injury in patients with AP. It is often thought that stress cardiomyopathy can induce these changes leading to type 2 myocardial infarction (type 2 MI) in AP. Our study aims to assess the prevalence as well as the impact of type 2 MI on outcomes in patients with AP. Methods National Inpatient Sample (NIS) 2016-2020 was used to identify adult patients (age>18) with acute pancreatitis. We excluded patients with STEMI, NSTEMI, pancreatic cancer, or chronic pancreatitis. Patients with missing demographics and mortality were also excluded. Patients were stratified into two groups, based on the presence of type 2 MI. Multivariate logistic regression analysis was performed to assess the impact of concomitant type 2 MI on mortality, sepsis, acute kidney injury (AKI), ICU admission, deep venous thrombosis (DVT), and pulmonary embolism (PE) after adjusting for patient demographics, hospital characteristics, etiology of AP and the Elixhauser comorbidities. Results Of the 1.1 million patients in the study population, only 2315 patients had type 2 MI. The majority of the patients in the type 2 MI group were aged >65 years (49.2%, p<0.001),<0.001),<0.001),<0.001),<0.001),<0.001)<0.001).<0.001).<0.001)<0.001).

A case of metastatic breast cancer complicated by pulmonary tumor thrombotic microangiopathy

Zhonghua Jie He He Hu Xi Za Zhi. 2023 Oct 12;46(10):1014-1018. doi: 10.3760/cma.j.cn112147-20230521-00253.

ABSTRACT

Pulmonary tumor thrombotic microangiopathy is a malignancy-related complication with rapid progression and high mortality. To improve the understanding of the disease, early diagnosis and treatment are key to successful treatment. A 39-year-old patient with pulmonary hypertension transferred from another hospital was admitted to the First Affiliated Hospital of Guangzhou Medical University on September 26, 2021. The patient developed shortness of breath and progressive exacerbation over the past month. No pulmonary artery embolism was seen on computed tomography pulmonary angiography (CTPA) at the outside hospital where the breast cancer was diagnosed. Pulmonary tumor thrombotic microangiopathy was immediately considered on admission and oncological endocrine therapy was started. After treatment, the patient's dyspnoea improved, PET-CT showed significant tumor regression, and cardiac ultrasound showed a significant decrease in pulmonary artery pressure. The successful treatment experience of this case was summarized for reference.

Risk of thromboembolic events associated with different multiple myeloma regimens in Taiwan: a nested case-control study

J Thromb Thrombolysis. 2023 Nov;56(4):578-587. doi: 10.1007/s11239-023-02887-7. Epub 2023 Sep 22.

ABSTRACT

Although novel agents for multiple myeloma (MM) have a better response rate and survival in both newly diagnosed and relapsed/refractory MM patients, concerns regarding the association between MM treatments and thromboembolic events have been raised. The aim of this population-based study was to examine the association between different combinations of MM treatments and the risk of thromboembolic events. We conducted a nested case-control study using the Taiwan Cancer Registry (TCR) and National Health Insurance Research Database (NHIRD). Adult patients newly diagnosed with MM and treated with at least one of the immunomodulatory agents between 2008 and 2016 were identified. Among them, we further identified patients who developed thromboembolic events as cases and selected controls matched by age, sex and duration of MM diagnosis at a ratio of 1:5. The index date was defined as the day one year before the diagnosis date of thromboembolic events in the case group and the corresponding date in the control group. Conditional logistic regression was used to examine the association between different MM treatment regimens and the risk of thromboembolic events. A total of 4,180 newly diagnosed MM patients treated with at least one of the immunomodulatory agents were identified (mean age: 67.2 years; male: 55.7%). In this MM cohort, we further identified 388 cases and 1,940 matched controls (mean age: 71 years; male: 64.2%). The use of a thalidomide/bortezomib/steroid combination (odds ratio (OR) 2.95 [95% confidence interval (CI) 1.47-5.95]), thalidomide monotherapy (OR 3.33; 95% CI, 1.59-6.94), and a thalidomide/steroid combination (OR 4.24; 95% CI, 2.00-8.98) were associated with an increased risk of thromboembolic events. Other risk factors, particularly a history of thromboembolic events, including ischemic heart disease and pulmonary embolism, were significantly associated with increased risk of thromboembolic events. We found that the use of thalidomide alone and in specific combinations was associated with an increased risk of thromboembolic events.

Survey on the Knowledge and Management of Cancer-Associated Thrombosis (CAT) in Haemato-Oncology Patients with Thrombocytopenia among Haematologists and Haematology Residents in Nigeria

West Afr J Med. 2023 Sep 28;40(9):956-961.

ABSTRACT

BACKGROUND: Arterial or venous thrombosis can complicate cancer, and 20% of cancer patients may develop venous thromboembolic disorders. Venous thromboembolism (VTE) is common in some haematologic malignancies and may coexist with thrombocytopenia in those haematologic malignancies. We carried out this survey to assess the knowledge and practice of haematologists and resident doctors in haematology in Nigeria regarding the management of thrombocytopenia and cancer-associated thrombosis.

METHODS: This was a survey that was shared electronically with participants who were consultant haematologists and resident doctors in haematology in Nigeria..

RESULTS: There were 106 respondents, 70 (66%) of which were consultant haematologists. About a third (30.2%) of the respondents saw 6-10 patients with blood malignancies monthly. Fifty-seven (53.8%) of the respondents carried out risk assessment in their patients for cancer-associated thrombosis (CAT); 63 (59.4%) of the respondents saw 1-2 cancer patients with thrombosis in 3 months. The most common mode of treatment was pharmacological - 94 (88%) respondents used low molecular weight heparin. The most common haematologic malignancies associated with thrombocytopenia were acute leukaemias (69; 67%). The most common decision taken by respondents was to stop anticoagulants and transfuse platelets because the most frequent concern was the risk of bleeding in this group of patients.

CONCLUSION: Many haematologists and haematology residents had a high level of awareness, knowledge and good practice regarding thrombocytopenia with CAT in haematooncology patients; however, there is a need for improved knowledge and unified protocols for treatment in line with newer management guidelines.

Trimodality therapy versus perioperative chemotherapy in the management of locally advanced adenocarcinoma of the oesophagus and oesophagogastric junction (Neo-AEGIS): an open-label, randomised, phase 3 trial

Lancet Gastroenterol Hepatol. 2023 Sep 18:S2468-1253(23)00243-1. doi: 10.1016/S2468-1253(23)00243-1. Online ahead of print. ABSTRACT

BACKGROUND: The optimum curative approach to adenocarcinoma of the oesophagus and oesophagogastric junction is unknown. We aimed to compare trimodality therapy (preoperative radiotherapy with carboplatin plus paclitaxel [CROSS regimen]) with optimum contemporaneous perioperative chemotherapy regimens (epirubicin plus cisplatin or oxaliplatin plus fluorouracil or capecitabine [a modified MAGIC regimen] before 2018 and fluorouracil, leucovorin, oxaliplatin, and docetaxel [FLOT] subsequently).

METHODS: Neo-AEGIS (CTRIAL-IE 10-14) was an open-label, randomised, phase 3 trial done at 24 centres in Europe. Patients aged 18 years or older with clinical tumour stage T2-3, nodal stage N0-3, and M0 adenocarcinoma of the oesophagus and oesophagogastric junction were randomly assigned to perioperative chemotherapy (three preoperative and three postoperative 3-week cycles of intravenous 50 mg/m2 epirubicin on day 1 plus intravenous 60 mg/m2 cisplatin or intravenous 130 mg/m2 oxaliplatin on day 1 plus continuous infusion of 200 mg/m2 fluorouracil daily or oral 625 mg/m2 capecitabine twice daily up to 2018, with four preoperative and four postoperative 2-week cycles of 2600 mg/m2 fluorouracil, 85 mg/m2 oxaliplatin, 200 mg/m2 leucovorin, and 50 mg/m2 docetaxel intravenously on day 1 as an option from 2018) or trimodality therapy (41·4 Gy in 23 fractions on days 1-5, 8-12, 15-19, 22-26, and 29-31 with intravenous area under the curve 2 mg/mL per min carboplatin plus intravenous 50 mg/m2 paclitaxel on days 1, 8, 15, 22, and 29). The primary endpoint was overall survival, assessed in all randomly assigned patients who received at least one dose of study drug, regardless of which study drug they received, by intention to treat. Secondary endpoints were disease-free survival, site of treatment failure, operative complications, toxicity, pathological response (complete [ypT0N0] and major [tumour regression grade 1 and 2]), margin-free resection (R0), and health-related quality of life. Toxicity and safety data were analysed in the safety population, defined as patients who took at least one dose of study drug, according to treatment actually received. The initial power calculation was based on superiority of trimodality therapy (n=366 patients); it was adjusted after FLOT became an option to a non-inferiority design with a margin of 5% for perioperative chemotherapy (n=540). This study is registered with ClinicalTrials.gov, NCT01726452.

FINDINGS: Between Jan 24, 2013, and Dec 23, 2020, 377 patients were randomly assigned, of whom 362 were included in the intention-to treat population (327 [90%] male and 360 [99%] White): 184 in the perioperative chemotherapy group and 178 in the trimodality therapy group. The trial closed prematurely in December, 2020, after the second interim futility analysis (143 deaths), on the basis of similar survival metrics and the impact of the COVID-19 pandemic. At a median follow-up of 38·8 months (IQR 16·3-55·1), median overall survival was 48·0 months (95% CI 33·6-64·8) in the perioperative chemotherapy group and 49·2 months (34·8-74·4) in the trimodality therapy group (3-year overall survival 55% [95% CI 47-62] vs 57% [49-64]; hazard ratio 1·03 [95% CI 0·77-1·38]; log-rank p=0·82). Median disease-free survival was 32·4 months (95% CI 22·8-64·8) in the perioperative chemotherapy group and 24·0 months (18·0-40·8) in the trimodality therapy gro[...]
