ABSTRACT

Patients diagnosed with cancer often experience an abnormal occurrence of venous thromboembolism (VTE) and its related complications. In order to evaluate the safety and effectiveness of both treatment approaches, we conducted a comprehensive systematic review and meta-analysis within the realm of cancer-associated thromboembolism. A thorough search was conducted across PubMed, the Cochrane Library, and Embase databases to find studies comparing direct oral anticoagulants (DOACs) with low molecular weight heparins (LMWHs) for the treatment of VTE in patients with malignancy. The analyses utilized the random-effects model. This meta-analysis included 11 studies. The results showed that DOACs were associated with a significantly reduced risk of VTE recurrence (RR: 0.67; 95% CI: 0.55, 0.81, p<0.0001;<0.0001;

Estrogen-based hormonal therapy and the risk of thrombosis in COVID-19 patients

Eur J Haematol. 2023 Jul 30. doi: 10.1111/ejh.14061. Online ahead of print.

ABSTRACT

OBJECTIVE: Estrogen-containing contraceptives and hormone replacement therapy are used commonly, however, the risks of venous and arterial thrombosis imparted by such medications during COVID-19 infection or other similar viral infections remain undescribed.

METHODS: To assess the risk of venous and arterial thrombosis in patients receiving oral estrogen-containing therapy (ECT) with COVID-19 as compared to those receiving non-estrogen-based hormonal therapy, we conducted a multicenter cohort study of 991 patients with confirmed COVID-19 infection, 466 receiving estrogen-containing hormonal therapy, and 525 receiving progestin-only or topical therapy.

RESULTS: The use of estrogen-containing therapy was found to significantly increase the risk of venous thromboembolism (VTE) following COVID-19 diagnosis after controlling for age (HR 5.46 [95% CI 1.12-26.7, p = .036]). This risk was highest in patients over age 50, with 8.6% of patients receiving estrogen-containing therapy diagnosed with VTE compared to 0.9% of those receiving non-estrogen-based therapies (p = .026). The risk of arterial thrombosis was not significantly associated with oral estrogen use.

CONCLUSIONS: These results suggest that estrogen-containing therapy is associated with a significantly increased risk of VTE in COVID-19 patients, especially in older individuals. These findings may guide provider counseling and management of patients with COVID-19 on estrogen-containing therapy.

How to Treat Today? Oral and Facial Cancer-Associated Venous Thromboembolism

Pharmaceuticals (Basel). 2023 Jul 17;16(7):1011. doi: 10.3390/ph16071011.

ABSTRACT

The exact incidence of cancer-associated venous thromboembolism (CA-VTE) in patients with oral and facial cancer (OFC) is not exactly known, and this risk is empirically considered to be low. However, this suggestion may result in disease underdiagnosis, prolong the initiation of adequate therapy, and consecutively increase CA-VTE-related morbidity and mortality. In addition, there might be specific clinical problems in the treatment of CA-VTE in patients with oral and facial cancer, such as swallowing difficulties, that might limit the possibilities of oral anticoagulation. Finally, there are limited data regarding the optimal treatment of CA-VTE in patients with oral and facial cancer, and this includes data on novel therapeutic strategies, including the use of direct oral anticoagulants. This article reviews current data on the optimal treatment strategy for CA-VTE in patients with OFC.

Thoracic Diseases: Technique and Applications of Dual-Energy CT

Diagnostics (Basel). 2023 Jul 21;13(14):2440. doi: 10.3390/diagnostics13142440.

ABSTRACT

Dual-energy computed tomography (DECT) is one of the most promising technological innovations made in the field of imaging in recent years. Thanks to its ability to provide quantitative and reproducible data, and to improve radiologists' confidence, especially in the less experienced, its applications are increasing in number and variety. In thoracic diseases, DECT is able to provide well-known benefits, although many recent articles have sought to investigate new perspectives. This narrative review aims to provide the reader with an overview of the applications and advantages of DECT in thoracic diseases, focusing on the most recent innovations. The research process was conducted on the databases of Pubmed and Cochrane. The article is organized according to the anatomical district: the review will focus on pleural, lung parenchymal, breast, mediastinal, lymph nodes, vascular and skeletal applications of DECT. In conclusion, considering the new potential applications and the evidence reported in the latest papers, DECT is progressively entering the daily practice of radiologists, and by reading this simple narrative review, every radiologist will know the state of the art of DECT in thoracic diseases.

The use of bevacizumab in primary malignant tumors of the central nervous system: A single-center experience

Medicine (Baltimore). 2023 Jul 28;102(30):e34286. doi: 10.1097/MD.0000000000034286.

ABSTRACT

Primary central nervous system tumors rank 8 among other cancers in patients over 40 years of age. Glioblastoma is the most common primary central nervous system malignancy, accounting for 48 percent of the cases. The present study evaluates the effect of bevacizumab on the disease course in patients who received bevacizumab therapy due to primary central nervous system tumors in our clinic. The study was designed as a retrospective study. The records of patients treated between January 2000 and August 2021 were reviewed and patients who received bevacizumab therapy due to primary central nervous system tumor were included in the study to evaluate the effect of the therapy on disease course among the subgroups of patients. The study included 70 patients. Of these patients, 40 were male (57.1%) and 30 (42.9%) were female. The median duration of follow-up was 28 months (8-209 months). The median age of the patients was 47 years. The median duration of exposure to bevacizumab was 5 months (1-33 months). Forty-nine patients (71.4%) were histologically diagnosed with glioblastoma multiforme. The median progression-free survival (PFS) was 5 months (95% confidence interval 4-6). The median overall survival (OS) was 8 months (95% confidence interval 6.97-9.02). No statistically significant difference in OS or PFS was observed in any patient subgroup. The therapy was discontinued only in 2 patients (2.9%) due to side effects (1 patient with pulmonary embolism and 1 patient with intracranial hemorrhage). The present study found that the use of bevacizumab is safe in terms of side effects. No statistically significant difference in OS or PFS was observed in any patient subgroup. There is a need for studies on a larger number of patients to find out which patient subgroup benefit the most from bevacizumab therapy.

A case report of Trousseau syndrome

Medicine (Baltimore). 2023 Jul 28;102(30):e34449. doi: 10.1097/MD.0000000000034449.

ABSTRACT

RATIONALE: In 1865, Trousseau first discovered pulmonary embolism caused by multiple venous thrombosis in patients with gastric cancer, and later all clinical manifestations of malignant patients during pathogenesis due to abnormal coagulation and fibrinolysis were referred to collectively as Trousseau syndrome. Trousseau syndrome is not a benign thrombophlebitis, and when diagnosed it requires immediate treatment. The survival rate over 1 year is only 12%. Stroke in cancer patients has distinct characteristics different from conventional stroke and has higher mortality.

PATIENT CONCERNS: A 54-year-old female presented to the Department of Otolaryngology with recurrent right nasal bleeding for 4 days. After surgery, the patient experienced 7 different cerebral infarction courses. Finally died of brain herniation.

DIAGNOSIS: The specific abnormal laboratory index is the increase of D-dimer, suggesting the hypercoagulation state. The patient developed multiple cerebral infarction, myocardial injury, renal infarction, splenic infarction, and lower extremity arterial thrombosis, and finally was diagnosed Trousseau syndrome.

INTERVENTIONS: In the treatment, aspirin and atorvastatin were selected, but it did not work very well. D-dimer were high, we used low molecular weight heparin, and D-dimer decreased significantly.

OUTCOMES: Finally the patient died of brain herniation.

CONCLUSION: The raise of D-dimer and typical magnetic resonance imaging manifestation which provides a greater basis for diagnosis. The specific abnormal laboratory index is the increase of D-dimer, which provides direction for treatment and helps to evaluate treatment effect.

Venous Thromboembolism and Primary Thromboprophylaxis in Perioperative Pancreatic Cancer Care

Cancers (Basel). 2023 Jul 8;15(14):3546. doi: 10.3390/cancers15143546.

ABSTRACT

Recent studies have shown that patients with pancreatic ductal adenocarcinoma (PDAC) treated with neoadjuvant chemo(radio)therapy followed by surgery have an improved outcome compared to patients treated with upfront surgery. Hence, patients with PDAC are more and more frequently treated with chemotherapy in the neoadjuvant setting. PDAC patients are at a high risk of developing venous thromboembolism (VTE), which is associated with decreased survival rates. As patients with PDAC were historically offered immediate surgical resection, data on VTE incidence and associated preoperative risk factors are scarce. Current guidelines recommend primary prophylactic anticoagulation in selected groups of patients with advanced PDAC. However, recommendations for patients with (borderline) resectable PDAC treated with chemotherapy in the neoadjuvant setting are lacking. Nevertheless, the prevention of complications is crucial to maintain the best possible condition for surgery. This narrative review summarizes current literature on VTE incidence, associated risk factors, risk assessment tools, and primary thromboprophylaxis in PDAC patients treated with neoadjuvant chemo(radio)therapy.
