Experiments were made to evaluate the potential role played by thrombogenic factors on the hematogenous arrest of circulating tumor cells in mice with demonstrable coagulopathies associated with the presence of a primary tumor, by administration of "therapeutic" doses of anticoagulants. The effects of warfarin, aspirin and heparin administration on the early arrest patterns of 125IdUrd-labelled TA3 carcinoma and Gardner lymphosarcoma cells injected intravenously into tumor-bearing mice were examined. Several hematologic parameters of carcinoma- and lymphosarcoma-bearing animals were measured prior to anticoagulation experiments and the results indicated that mice had coagulopathies similar to those found in cancer patients with disseminated intravascular coagulation syndrome, i.e., thrombocytopenia and elevated fibrinogen levels. Despite the presence of coagulation abnormalities and effective anticoagulation in recipient animals, all three agents were without effect on localization patterns of both tumor types. It was concluded that the proposed involvement of thrombogenesis in metastasis was probably not due to any role played by those clotting factors inhibited by aspirin, warfarin and heparin in early intravascular tumor cell arrest.

Three patients with acute lymphoblastic leukemia and one with lymphosarcoma cell leukemia developed transient hypofibrinogenemia during a course of treatment with vincristine and prednisone. There was no evidence of overt, disseminated intravascular coagulation or significant liver impairment. Fibrinogen survival using homologous-125-I-labelled fibrinogen was measured in two patients; it was moderately shortened in both, perhaps indicating subclinical intravascular coagulation. Rapid lysis of leukemic cells might have been responsible for activating coagulation and fibrinolysis in vivo. These four patients, however, were not different in any clinical or laboratory parameter from nine others with lymphoblastic leukemia similarly treated and investigated without observing any defect in their fibrinogen. There were no bleeding complications and the fibrinogen level became normal within 13 to 30 days.

Thirty-two children with solid tumors (lymphangioma, fibrosarcoma, hepatocarcinoma, osteogenic sarcoma, rhabdomyosarcoma, lymphosarcoma, mesenchymoma, hepatoma, Ewing's sarcoma, reticulum cell sarcoma, neuroblastoma, Hodgkin's disease, and brain tumors) were studied for alterations in coagulation by means of platelet counts, platelet aggregation, thrombelastogram, procoagulant and antigenic factor VIII, fibrin split products, and antithrombin III level. Results indicated hypercoagulability as shown by abnormally short thrombelastograms and elevated factor VIII levels and platelet counts in approximately one-half of the group. With the exception of increased fibrin split products in a third of the patients, little laboratory or clinical evidence for disseminated intravascular coagulation was seen. Hypercoagulability, as noted in adult carcinoma patients, can also occur in childhood sarcoma patients.

Six cases of disseminated intravascular coagulation in the horse are reported. They were characterised clinically by severe subcutaneous oedema of the head and neck, and clinocopathologically by abnormal partial thromboplastin and prothrombin times, a thrombocytopaenia and an increase in fibrin degradation product concentrations. Various aetiologies played a role in the pathogenesis of the condition including African horsesickness, babesiosis, lymphosarcoma and verminosis.

Twelve dogs with lymphosarcoma and hypercalcemia were treated over a period of 36 months. Signs and laboratory findings were referable to hypercalcemia and azotemia. All dogs were staged, classified histologically, and given cytoreductive chemotherapy, using 5 drugs (vincristine sulfate, cytosine arabinoside, cyclophosphamide, L-asparaginase and prednisone). For azotemia, symptomatic therapy (0.9% NaCl solution and furosemide) was given. Seven dogs responded completely, with marked reduction of lymphadenopathy and return of serum calcium concentration to normal. Median duration of remission in this group was 48 days (range, 14 to 93), and median survival time was 112 days (range, 85 to 153). Five nonresponding dogs had less than 50% reduction in measurable tumor mass, although serum calcium concentration returned to normal. The median survival time for this group was 34 days (range, 23 to 68). Two of the nonresponders died from sepsis and another from disseminated intravascular coagulation. Response to therapy did not appear to be influenced by age, breed, sex, initial calcium concentration, degree of azotemia, or histologic classification.

Thrombocytopenia in horses may be idiopathic or secondary to chronic infectious or inflammatory diseases (eg, equine infectious anemia, lymphosarcoma), drug administration, bone marrow depression, myelophthisic disease, or disseminated intravascular coagulation. This report describes EDTA-dependent pseudothrombocytopenia in a horse. Platelet counts for blood containing EDTA were consistently less than reference range, but platelet counts of blood containing heparin were within reference range. When thrombocytopenia is diagnosed in horses without clinical evidence of a bleeding tendency, EDTA-dependent pseudothrombocytopenia should be considered. The diagnosis can be confirmed simply by screening blood films for platelet clumps and by comparing platelet counts of paired blood samples, one containing EDTA and the other containing heparin.

An 11-year-old mixed-breed dog was examined because of chronic diarrhea, anorexia, and weight loss. Clinicopathologic abnormalities included anemia and hypoalbuminemia, and protein-losing enteropathy was identified. Acute, unilateral, femoral artery thrombosis developed before the cause of the protein-losing enteropathy could be identified. The dog was treated with aspirin, and sensation and function of the affected limb returned over the next 5 days, but thrombosis of the opposite femoral artery then developed. The dog was euthanatized, and at necropsy, intestinal lymphosarcoma was the only disease process found. Although disseminated intravascular coagulation is a well-recognized potential complication of neoplasia in dogs, recurrent localized thrombosis, as in this dog, also can develop.
