Bone is a common site of metastasis in human cancer. A major impediment to understanding the pathogenesis of bone metastasis has been the lack of an appropriate animal model. In this paper, we describe an animal model in which B16 melanoma cells injected in the left cardiac ventricle reproducibly colonize specific sites of the skeletal system of mice. Injection of 10(5) cells resulted in melano...

Intracavitary cardiac extension remains an unusual site of extrahepatic metastasis in patients with hepatocellular carcinoma. While patients can present with signs and symptoms suggestive of right-sided heart failure, it may be totally asymptomatic, which is very rare with only a few cases reported so far. Also, cardiac metastasis is of great prognostic importance as patients with intracardiac ...

Bone metastasis is a lethal and morbid late stage of breast cancer that is currently treatment resistant. More effective mouse models and treatment are necessary. High bone-metastatic variants of human breast cancer cells were selected in nude mice by cardiac injection. After cardiac injection of a high bone-metastatic variant of breast cancer, all untreated mice had bone metastases compared to...

A 59-year-old man developed an episode of syncope while he was driving. This resulted in a motor vehicle accident, and the patient sustained an open fracture of the left femur. Biopsy of the left femur fracture showed a metastastic renal cell carcinoma, and echocardiography revealed a right ventricular mass without contiguous vena caval or right atrial involvement. This is one of the few report...

Introduction: Myocardial metastasis from lung cancer is rarely found in antemortem settings. Herein we present a case of myocardial metastasis from lung adenocarcinoma presenting as cerebral infarction. Case Report: A 78­year­old Japanese female (non­smoker) who had been diagnosed with poorly differentiated lung adenocarcinoma suddenly complained of weakness in the left hand on a regular follow...
