Abstract
Tumor thrombus, the intravascular extension of tumor into adjacent blood vessels, is frequently encountered in patients with renal cell carcinoma and hepatocellular carcinoma, and often involves the abdominal vasculature including the renal vein, portal vein, and the inferior vena cava. While a bland thrombus is composed of platelets and fibrin, in contrast, a tumor thrombus refers to an organized collection of tumor cells. Though oftentimes detected incidentally on imaging, tumor thrombus may have significant clinical implications and can be challenging to differentiate from bland thrombus. Additionally, the optimal management of tumor thrombus, including the use of anticoagulation, remains poorly described. This review summarizes common causes of tumor thrombus, as well as its impact on staging, prognosis, and treatment.

Hussain SMA. Lung cancer embolization causing acute limb ischemia: a case report. J Med Case Rep 2023; 17:56. [PMID: 36797755 PMCID: PMC9936652 DOI: 10.1186/s13256-023-03769-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 01/09/2023] [Indexed: 02/18/2023] Open
Abstract
BACKGROUND Acute tumour embolism to the popliteal artery resulting in limb-threatening ischemia is a rare complication of neoplastic disease. Generally, tumors embolize to the pulmonary circulation via the venous system. In this case, the originating tumor was a lung cancer of a large size and advanced stage that had invaded the left atrium of the heart and disseminated in the systemic circulation. The tumor likely fragmented, resulting in showering to the right popliteal artery, superior mesenteric artery, and left renal artery, which is a unique presentation of tumor embolism. CASE REPORT We present a case of a 62-year-old Caucasian gentleman with a large left lower lobe squamous cell lung cancer that had invaded into the left atrium via the pulmonary veins. He presented with acute limb threatening ischemia. A computed tomographic angiogram revealed an occlusion of the left popliteal artery as well as embolization to the superior mesenteric artery and the right renal artery. He was started on intravenous heparin and underwent an emergency popliteal embolectomy and calf fasciotomies, which was limb saving. His fasciotomy wounds were closed after 1 week and he was discharged on anticoagulation. CONCLUSION This is a rare case of tumor embolism resulting in both an embolectomy and calf fasciotomies. In the light of such cases, we suggest that tumors invading the bloodstream should be considered high risk for embolization and hypothesize that prophylactic antithrombotic therapy may avoid major morbidity.

Abstract
Tumor-based arterial thromboembolism in patients with cancer is a poorly described concept that lacks evidence for surgical indications owing to its unusual occurrence. The study and understanding of this condition’s etiology is, however, essential because it could constitute the initial presentation or determine the prognosis of oncologic disease. In the present report, we have described the case of a 77-year-old female patient with multiple cerebral, splenic, and upper limb arterial embolic episodes. Embolectomy for acute upper limb ischemia revealed the histopathologic diagnosis of an anaplastic thyroid tumor.

Abstract
Limb ischemia caused by tumor embolus is rare. In this study, we report the case of a 77-year-old woman who suffered from acute ischemic limb. Computed tomography showed a tumor in the right bronchus invading the left atrium. The tumor fragments scattered resulting in the occlusion of the right iliac artery. The excluded embolus was revealed as a squamous cell carcinoma. Regarding the popliteal venous thrombus, Trousseau’s syndrome was complicated. The patient was discharged without any complications. We believe that advanced lung cancer is a differential diagnosis of acute ischemic limbs and that successful limb rescue contributed to a patient’s quality of life.

A systematic review and meta-analysis of outcomes after acute limb ischemia in patients with cancer. J Vasc Surg 2021; 74:1033-1040.e1. [PMID: 33905869 DOI: 10.1016/j.jvs.2021.03.058] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Accepted: 03/26/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND Cancer results in a hypercoagulable state that is associated with both venous and arterial thromboses. However, little is known about the effects of acute limb ischemia (ALI) in this cohort of patients. In the present systematic review and meta-analysis, we analyzed the available clinical data on cancer and its association with ALI and evaluated the outcomes in these patients after a diagnosis of ALI. METHODS Three databases, including PubMed, EMBASE, and the Cochrane Library, were queried. Studies that met the inclusion criteria were included regardless of the publication year, language, sample size, or follow-up length. All the steps of the meta-analysis were conducted in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) and MOOSE (meta-analysis of observational studies in epidemiology) guidelines. RESULTS Seven studies from 6222 references with a total of 2899 patients were included. Of the 2899 patients, 1195 (41%) had had a diagnosis of ALI before their cancer diagnosis, and 1704 (59%) had presented with ALI after a cancer diagnosis. Nearly three quarters of ALI events were among patients with cancer of the skin and soft tissue (19%), genitourinary (18%), lung (17%), and gastrointestinal (16%) systems. ALI recurrence was similar between the two groups, and major amputation was more likely in patients with a diagnosis of ALI after a cancer diagnosis (7.4% vs 4.6%; P < .01). The incidence of mortality at 1 year was significantly greater for patients with established cancer who had presented with ALI compared with the patients who had presented with ALI before a cancer diagnosis (50.6% vs 29.9%; P < .01). After adjusting for study variability using the random effects model, the mortality at 1 year for all patients was 52.3% (95% confidence interval, 37.7%-66.5%). No significant heterogeneity (P = .73) was found between the two groups of patients, which varied by the timing of the ALI diagnosis in relation to the cancer diagnosis. CONCLUSIONS The 1-year mortality after the development of ALI in patients with cancer was >50%. For patients presenting with ALI of unclear etiology, the presence of an underlying cancer should be considered.

Abstract
Acute ischemic events secondary to pulmonary malignancy are rare. Those who present with acute peripheral arterial occlusions from malignant sources will typically have advanced pulmonary malignancy or myxomatous tumors. A 79-year-old woman had presented to Vancouver General Hospital with acute mesenteric ischemia. The pathology reports after embolectomy indicated cell morphology consistent with spindle cell carcinoma of the lung. Imaging investigations revealed a right upper lobe mass not present on chest imaging studies performed 14 months previously. The findings from the present report serves to remind us that acute ischemic events in the setting of no known history of malignancy or cardiac disease should prompt investigations into possible malignant sources.
