Hypofibrinogenemia and disseminated intravascular coagulation are common events in patients with metastatic prostate carcinoma. This study tests the hypothesis that prostate tumor growth and metastasis is associated with sustained activation of fibrinolysis secondary to increased release of plasminogen activator. We implanted an androgen-insensitive prostate tumor into an inbred strain of rats and serially measured plasminogen, plasminogen activator, plasmin and fibrinogen. Control groups included animals without tumor and a group implanted with transitional cell bladder carcinoma, a locally infiltrating tumor not usually associated with hemostatic complications. Our results showed a significant and steady rise in plasma plasminogen activator, plasmin and fibrinogen levels in animals implanted with prostate cancer. This, however, is not specific for prostate tumor. Similar, perhaps more profound changes were noted in animals implanted with the transitional cell carcinoma.

A 44-year-old woman with an unusual form of pulmonary metastasis is described. She presented with pulmonary thrombosis and clinical signs of disseminated intravascular coagulation (DIC) and died of cerebral hemorrhage. The autopsy study revealed transitional cell carcinoma of the left renal pelvis with pulmonary thrombosis in the large arteries. The intima of the vessels were intact on gross inspection except where the thrombi adhered to. The thrombi contained no tumor cells. However, microscopic examination identified that the metastatic carcinoma diffusely replaced the endothelium and proliferated on to the intimal surface without invasion of the wall and metastatic nodules in the parenchyma. Other examined organs had neither primary nor metastatic tumors, except for microscopic metastasis to the inferior vena cava. To date, this pattern of metastasis has not been noted in previous literature. This condition was designated as being vascular intimal carcinomatosis because of its characteristic manner of tumor proliferation on vascular intima.

BACKGROUND: Disseminated Intravascular Coagulation (DIC) complicates up to 7% of malignancies, the commonest solid organ association being adenocarcinoma. Transitional Cell Carcinoma (TCC) has rarely been associated with DIC. CASE PRESENTATION: A 74-year-old woman with TCC bladder and DIC was found to have a cardiac lesion suspicious for metastatic disease. The DIC improved with infusion of plasma and administration of Vitamin K, however the cardiac lesion was deemed inoperable and chemotherapy inappropriate; given the patients functional status. We postulate that direct activation of the coagulation cascade by the intraventricular metastasis probably triggered the coagulopathy in this patient. CONCLUSION: Cardiac metastases should be considered in cancer patients with otherwise unexplained DIC. This may influence treatment choices.

We report a rare case of symptomatic cardiac metastasis from a transitional cell carcinoma of the renal pelvis. A 57-year-old man presented with severe anemia, inflammation, hypoxemia and disseminated intravascular coagulation. Computed tomography revealed a large tumor in the left renal pelvis with multiple lymph node metastases. Two-dimensional echocardiography revealed large tumors in the right ventricle. The patient suddenly died because of the obstructive mass of the right ventricular outflow tract. Histopathological examination showed high-grade transitional cell carcinoma in the left renal pelvis and the right ventricle. There are only three cases of cardiac metastases from a transitional cell carcinoma reported in the literature.
