ABSTRACT

BACKGROUND: Germ cell tumours (GCT) are highly curable malignancies. Venous thromboembolism (VTE) is a serious complication, needing better risk assessment models (RAM).

AIM: Identification of VTE incidence and risk factors in metastatic GCT patients starting first-line chemotherapy. Developing a RAM and comparing it to Khorana risk score (KRS) and Padua Prediction Score (PPS).

MATERIAL AND METHODS: We retrospectively analysed GCT patients staged IS-IIIC. VTE risk factors were identified with logistic regression. Area under curve of receiver operating characteristic (AUC-ROC), Akaike and Bayesian Information Criteria (AIC, BIC) were calculated for the developed RAM, KRS and PPS.

RESULTS: Among 495 eligible patients, VTE occurred in 69 (13.9%), including 40 prior to chemotherapy. Vein compression (OR: 8.96; 95% CI: 2.85-28.13; p < 0.001), clinical stage IIIB-IIIC (OR: 5.68; 95% CI: 1.82-17.70; p = 0.003) and haemoglobin concentration (OR for 1 g/dL decrease: 1.32; 95% CI: 1.03-1.67; p = 0.026) were significant in our RAM. KRS ≥ 3 (OR: 3.31; 95% CI: 1.77-6.20; p < 0.001), PPS 4-5 (OR: 3.06; 95% CI: 1.49-6.29; p = 0.002) and PPS > 5 (OR 8.05; 95% CI 3.79-17.13; p < 0.001) correlated with VTE risk. Diagnostic criteria (AUC-ROC, AIC, BIC) for the developed RAM, KRS and PPS were (0.885; 0.567; -1641), (0.588; 0.839; -1576) and (0.700; 0.799; -1585), respectively. In the numerical score, the optimal cut-off point for high-risk was ≥9, with sensitivity, specificity, positive and negative predictive value of 0.78, 0.77, 0.35 and 0.96, respectively.

CONCLUSIONS: Our RAM, based on vein compression, clinical stage and haemoglobin concentration proved superior to both KRS and PPS. VTE is frequent in GCT patients.

A case of pulmonary tumor embolism syndrome with thrombus in transit

Respir Med Case Rep. 2023 Jul 20;45:101896. doi: 10.1016/j.rmcr.2023.101896. eCollection 2023.

ABSTRACT

The incidence of pulmonary tumor embolism in patients with solid tumors is estimated to be between 3% and 26% yet is rarely diagnosed. In this case, a 74-year-old male with sarcomatoid variant of urothelial carcinoma and recently diagnosed left renal vein thrombus treated with low-molecular-weight-heparin, presented to the emergency department with acute syncope and dyspnea. He was found to have CT imaging of segmental and subsegmental arterial filling defects, a right atrial filling defect concerning for thrombus in transit and was diagnosed with pulmonary tumor embolism syndrome. The patient was treated with aspiration thrombectomy, with pathology demonstrating sarcomatoid urothelial carcinoma cells. He was initiated on a combination of gemcitabine plus carboplatin to decrease the tumor burden. While pulmonary tumor embolism syndrome is associated with a poor prognosis, prompt diagnosis and initiation of cancer-specific therapies can significantly improve survival.

Rivaroxaban Versus Low-Molecular-Weight Heparins in a Broad Cohort of Patients With Cancer-Associated Venous Thromboembolism: An Analysis of the OSCAR-US Program

Clin Appl Thromb Hemost. 2023 Jan-Dec;29:10760296231189282. doi: 10.1177/10760296231189282.

ABSTRACT

Cancer-associated venous thromboembolism (CAT) guidelines recommend direct oral anticoagulants as alternatives to low-molecular-weight heparin (LMWH) in most patients. This study compared the effectiveness and safety of rivaroxaban versus LMWH for a broad CAT cohort. The cohort study used electronic health data from January 2012 to December 2020 to evaluate patients with active cancer experiencing acute venous thromboembolism (VTE) and treated with rivaroxaban or LMWH. Propensity score-overlap weighted hazard ratios (HRs) and 95% confidence intervals (CIs) for VTE, bleeding-related hospitalization, and all-cause mortality were calculated. In total, 4935 patients were identified (27.9% on rivaroxaban and 72.1% on LMWH). The cancer types included gastrointestinal (29.4%), genitourinary (26.2%), lung (24.0%), breast (19.7%), and hematologic (14.4%). Rivaroxaban was associated with a reduction in recurrent VTE versus LMWH among all patients with cancer (HR = 0.78; 95%CI = 0.61-0.99) at 3 months. No differences in bleeding-related hospitalization or all-cause mortality were observed. Directionally similar results to those at 3 months were observed at 6 months for all outcomes. In conclusion, we observed fewer recurrent VTE cases and no increase in bleeding-related hospitalizations with rivaroxaban versus LMWH at 3 months in this patient cohort with various cancer types.

Venous thromboembolism in multiple myeloma: Increasing evidence in support of direct oral anticoagulants

Br J Haematol. 2023 Aug 15. doi: 10.1111/bjh.19056. Online ahead of print.

ABSTRACT

Venous thromboembolism (VTE) continues to cause significant morbidity and excess mortality in patients with multiple myeloma. The report by Costa and colleagues demonstrates superiority of direct oral anticoagulants over aspirin in terms of VTE prevention, without increased bleeding complications seen. Commentary on: Costa et al. Direct oral anticoagulants versus aspirin for primary thromboprophylaxis in patients with multiple myeloma undergoing outpatient therapy: A systematic review and updated meta-analysis. Br J Haematol 2023 (Online ahead of print). doi: 10.1111/bjh.19017.

Giant breast phyllodes tumor with silent thromboembolism: A case report

Cancer Rep (Hoboken). 2023 Aug 14:e1865. doi: 10.1002/cnr2.1865. Online ahead of print.

ABSTRACT

BACKGROUND: Phyllodes tumor (PT) is a solid fibroepithelial breast lesion with proliferation of stromal and epithelial elements, usually presents with a rapidly expanding feature. Venous thromboembolism (VTE) have been reported to increase the burden in terms of mortality and morbidity of malignant tumor, and associate with worsened survival. However, benign PTs with silent thromboembolism that have not yet been reported, we report an unusual case of massive benign PT that grew on the left side of the breast in a cauliflower-shaped form and presented severe chronic blood loss and deep VTE.

CASE: A 37-year-old woman with uncontrolled pain presented a rapidly enlarging left breast mass, measuring approximately 30 × 20 × 15 cm3 that first started 25 years ago. color Doppler ultrasound showed a large mass lesion on the left breast and deep VTE, several enlarged lymph nodes in the left axilla and mediastinum, which presented a malignant character. However, the biopsies of the mass did not show evidence of malignancy and the pathology result was considered to be benign PT. The patient was treated with an inferior vena cava and anticoagulation, the operation was arranged according to the surgical procedure, the patient recovered very well after mastectomy.

CONCLUSION: This case is unique in that the giant breast mass presented with malignant character, was eventually pathologically confirmed to be benign PT, and it's rare that the benign tumor accompanied with silent thromboembolism. This finding describes the atypia features of giant benign PT and reminds the surgeon to consider the factor of VTE and risk when encountering ulcerative benign breast tumor and avoid excessive treatment.
