Resolution of nonbacterial endocarditis after surgical resection of a malignant liver tumor

Stroke and a valvular lesion in a patient with stage IV non-small cell lung cancer

The mechanism and severity of stroke varies in the setting of malignancy. We report a case of a 68-year-old man with lung adenocarcinoma, who experienced acute neurological symptoms. Imaging studies showed multiple acute ischaemic infarcts in cerebral and cerebellar hemispheres. Further work up was consistent with non-bacterial thrombotic endocarditis (NBTE). We highlight, through a review of the literature, the importance of transoesophageal echocardiography (TOE) in defining the above diagnosis. The treatment of NBTE consists of systemic anticoagulation and therapy of the underlying malignancy. Enoxaparin is preferred over warfarin to achieve this goal. He received systemic targeted therapy with erlotinib. A TOE performed 8 months later showed complete resolution of the vegetation.

Thromboembolic Events in the Cancer Patient

Thromboembolic events are a major cause of morbidity in cancer patients and may be harbingers of occult malignancy. Trousseau's syndrome (TS) is probably the best known thromboembolic syndrome in the cancer patient, encompassing a variety of paraneoplastic thromboembolic disorders. These include spontaneous recurrent or migratory venous thromboses and arterial emboli caused by nonbacterial thrombotic endocarditis in a patient with malignancy. Although linked to almost all cancers, venous thromboembolism (VTE) is a terminal event in many cancers occurring in women, such as breast, uterine, and lung cancers (Monreal et al. Thrombosis and Haemostasis 1997;78:1316). Appropriate recognition of the syndrome is paramount because TS often requires careful medical surveillance and management. Significant complications of thromboembolic events in the cancer patient include limb ischemia and deep venous thrombosis/pulmonary embolism, which can cause devastating and permanent consequences. The rehabilitation management of these complications is reviewed, with an emphasis on diagnostic and therapeutic approaches in this patient population.
