The vascular lesion of thrombotic thrombocytopenic purpura was characterized by two distinct types of changes in the arteriole of the heart and brain: (1) multiple incomplete vascular occlusions due to the subendothelial deposits composed of a homogeneous fibrin fibrinogen-like substance and platelets without the formation of polymerized fibrin; (2) vascular wall thickening due to the intramural granular deposits of IGM and beta 1C. A patient with hemolytic-uremic syndrome 9 days after the onset of the disease, exhibited (1) the formation of fibrin-thrombi in the glomerular capillary lumens, and (2) the granular deposits of IgM and beta 1C along the glomerular capillary walls and in the mesangium. In contrast, the case in which the symptoms subsided five weeks after the onset exhibited neither fibrin-thrombus formation nor the deposits of IgM and beta 1C in the glomeruli. The vascular lesions of disseminated intravascular coagulation accompanied by pancreas carcinoma was located mainly in the capillaries, and were characterized by the formation of numerous fibrin-thrombi. Although the glomeruli contained numerous thrombi, there was neither endocapillary proliferation nor deposits of immunoglobulins and complement components.

Plasma fibronectin was determined in 121 normal adults and in 149 patients. Fibronectin levels in normals were strongly influenced by sex and age. The mean value of the protein in cancer patients did not differ from that in normal controls; however, patients with cryofibrinogenaemia or extensive liver metastases had lower values whereas those with obstructive jaundice due to pancreatic carcinoma had higher values than normal controls. Fibronectin levels were greatly increased in patients with primary biliary cirrhosis and moderately elevated in nephrotic syndrome. In patients with severe infection or sepsis, plasma fibronectin did not show a consistent pattern. Patients with overt disseminated intravascular coagulation, irrespective of its cause, had the lowest plasma fibronectin concentrations.

Microangiopathic hemolytic anemia and thrombocytopenia secondary to disseminated intravascular coagulation is a well-described complication of widely metastatic carcinoma. The authors report four cases of gastric carcinoma, one case of colon cancer, and one case of adenocarcinoma of unknown primary in which the patient developed a syndrome analogous to thrombotic thrombocytopenic purpura, consisting of microangiopathic hemolytic anemia, thrombocytopenia, and renal failure without definite evidence of disseminated intravascular coagulation. In contrast to previous reports, postmortem examination in three of the cases revealed no recurrence or only microscopic foci of residual tumor. In the remaining three, there was clinical and pathologic evidence of grossly disseminated carcinoma. Also in contrast to previous cases, all patients evidenced azotemia and proteinuria at the onset of the syndrome and ultimately uremia was a contributing cause of death. Coagulation profiles showed prolonged thrombin times and elevated fibrin degradation products in four instances and did not distinguish the patients with grossly metastatic disease from those with no tumor or only microscopic residua. Circulating immune complexes containing carcinoembryonic antigen were found in the patient with metastatic colon carcinoma. The syndrome was clinically identical whether or not grossly metastatic tumor was present, and it should not be attributed to advanced disease without definite clinical or pathologic evidence of a recurrence.

Hemostatic abnormalities are rather frequent in cancer patients either in hematological or in solid tumors. Acute disseminated intravascular coagulation (DIC) is a rare coagulopathy in cancer patients, but when it develops it becomes rapidly fatal. Between June 1988 and December 1992 we observed 8 cases of acute DIC occurring in gastric cancer (4 patients), breast cancer (3 patients) and high-grade non-Hodgkin lymphoma (1 patient). In 3 patients affected by gastric carcinoma, acute DIC was the first manifestation of the presence of the tumor, while in the other patients DIC occurred during the course of the disease. All the patients were treated with heparin, fresh frozen plasma and platelet support, but only in 1 patient was a short duration improvement of clinical conditions and coagulation tests recorded. Acute DIC can be the first manifestation of gastric tumors and the presence of the hemorrhagic syndrome associated with thrombocytopenia, hypofibrinogenemia and fibrin/fibrinogen degradation products should initiate a search for gastric carcinoma.

Carcinoma of the prostate has historically been associated with the bleeding diathesis which accompanies disseminated intravascular coagulation. We have performed a prospective study into the prevalence of coagulopathy in patients with untreated prostate cancer using matched patients with benign prostatic hypertrophy (BPH) as controls. Haemostatic activation was assessed by measuring fibrinopeptide A (FpA) by an ELISA and D-dimer by a latex agglutination assay. FpA and D-dimer levels were correlated with serum prostate specific antigen (PSA) and bone scan status. Of the cancer patients, 40% had elevated FpA, levels being higher in those with bone scan positive disease (P < 0.05). D-dimer was detectable in 24% of those with prostate cancer but in none with BPH. Neither FpA nor D-dimer were related to serum PSA but D-dimer appeared to be a predictor of bone scan status with a positive predictive value of 91%. It is concluded that changes compatible with subclinical DIC are common in patients presenting with prostate cancer and that measurement of FpA and D-dimer may have roles as tumour markers in this disease.

Thromboembolic complications are the second most common cause of death in hospitalized cancer patients; they are caused by alterations of hemostasis and include hypercoagulable states, acute and chronic disseminated intravascular coagulation, and primary fibrinolysis. The fibrinolytic system is comprised of several serine protease enzymes and their inhibitors and is associated in various biological systems with physiological and pathological events such as tissue development, remodeling, invasiveness, and migratory potentials of both normal and malignant cells. It also plays a key role in the dissolution of fibrin strands. Defective fibrinolysis, which is often associated with the pathogenesis of venous thrombosis and other thromboembolic complications, occurs when the balance is disrupted, resulting in either inhibition or enhancement of fibrinolysis. The association between thromboembolic complications and neoplastic disease has been well-established since Trousseau in 1865 first reported a high incidence of venous thrombosis in a series of patients with gastric carcinoma. In this article, we discuss the factors that have been shown to be associated with thromboembolic complications in patients who harbor brain tumors, namely, hemostatic alterations caused by the tumors themselves or through interactions with neural tissue around the tumors, pre-operative hemostatic alterations in certain patients, and defective fibrinolysis associated with specific tumor types and/or tumor locations.

Ten percent (214/2,059) of all dogs with cancer at North Carolina State University Veterinary Teaching Hospital had thrombocytopenia. The thrombocytopenia was associated with infectious/inflammatory etiologies in 4%, miscellaneous disorders (therapy, bone marrow failure, disseminated intravascular coagulation) in 35%, and neoplasia without identifiable secondary factors in 61% of cancer-bearing dogs. Classifying these dogs by tumor groups revealed the following proportionate ratios: lymphoid, 29%; carcinoma, 28%; sarcoma, 20%; hemic neoplasia, 7%; multiple, 5%; unclassified, 3%; benign, 3%; brain, 3%; and endocrine, 3%. Dogs with hemangiosarcoma, lymphoma, and melanoma were at increased risk of developing thrombocytopenia. Cytotoxic therapy was the major factor increasing the risk of thrombocytopenia in dogs with melanoma. Golden Retrievers were the only breed recognized with a predisposition to develop thrombocytopenia. If thrombocytopenia is identified in a dog with cancer, we recommend thorough evaluation of the coagulation system before surgery or therapy, and careful consideration of the risks and potential benefits of myelosuppressive or L-asparaginase therapy.

We describe a 39 years-old male hemophilia A patient with acquired immunodeficiency syndrome (AIDS) developing to disseminated intravascular coagulation (DIC) due to gastric carcinoma. He had been diagnosed as human immunodeficiency virus (HIV) sero-positive in 1990. Since then, he has been treated by the oral administration of zidovudine (AZT), dideoxyinosine (ddI) and intravenous administration of glycyrrhizin. In September 1990, he suddenly complained abdominal pain with bloody stool. His condition deteriorated in spite of our intensive treatment for DIC. He died of multiple organ failure (MOF) due to DIC. The autopsy findings showed gastric carcinoma, defined of signet ring cell carcinoma histopathologically. But neither opportunistic infection nor other cause of DIC were observed.

The unusual case of a 65-year-old woman with intermittent hypotension, fever, pulmonary edema and coma as initial presentation of pheochromocytoma is reported. The patient developed respiratory, cardiac and renal failure, disseminated intravascular coagulation and liver dysfunction. She had to be defibrillated on multiple occasions, occurring in periods of severe hypertension. After successful surgical removal of a pheochromocytoma a thyroid medullary carcinoma was detected. Several members of the patients family had presented with multiple endocrine neoplasia (MEN II).
