The paraneoplastic syndrome (PNS) is an association of symptoms and signs not directly related to the site or local manifestations of a malignant tumor or its metastases. Hematologic abnormalities as PNS include erythrocytosis, anemia, neutrophilia, neutropenia, eosinophilia, thrombocytosis, thrombocytopenia, venous thromboembolism and disseminated intravascular coagulation (DIC). These abnormalities are, by and large, due to the production of biologically active growth factors, hormones or as yet unidentified "humors" by the tumor. As our understanding of growth factors controlling hematopoiesis has increased in recent years, the biologic basis of hematologic PNS are better understood. For instance, tumor-associated neutrophilia is now known to be caused by the production of G-CSF by the tumor. The mechanism by which tumor causes thromboembolism have also been extensively investigated. Cancer cells induce platelet aggregation both in vitro and in vivo. Platelet aggregating material has been isolated and partially characterized from tumor cells. The involvement of platelet glycoprotein II b/IIIa in the tumor-platelet interaction has also been shown. Malignant cells contain a unique procoagulant, cancer procoagulant A, that directly activates factor X. Together with tissue factor, this procoagulant appears to have been contribute to a high incidence of thromboembolism in cancer patients. Better understanding of hematologic PNS is important for clinical care of the patients with cancer.

Derangements of hemostasis and hemocoagulation in patients with malignancies are known as paraneoplastic syndrome. Their origin, however, has not been unequivocally established and explained, and data on their occurrence are controversial. Examination of 157 patients with different malignant tumor diseases yielded pathological laboratory findings in 94.2%. The most frequent finding was the state of hypercoagulation in 41.0%; hypercompensated syndrome of disseminated intravascular blood clotting (DIC) was found in 10.9%, compensated DIC syndrome in 18.0%, consumptive coagulopathy in 3.8%, and in 19.2% hypocoagulation state caused by other abnormalities. The laboratory finding was normal only in 5.8% of the patients. In the light of the high occurrence rate of hemostatic and hemocoagulation changes in malignant diseases, established by laboratory analysis, the use of anticoagulants and antiaggregation substances appears to be justified in the majority of cases, both to prevent the development of these changes which may complicate the course of the malignant condition, and in preoperative care to reduce the rate of postoperative thromboses in patients with tumors.

Treatment for the paraneoplastic syndrome associated with lung cancer was reviewed. The principle of the treatment of paraneoplastic syndrome is to control cancer as an underlying disease. Therefore, the standard therapy for Cushing's syndrome associated with lung cancer is surgical treatment if the tumor is operable. There is no standard therapy for Cushing's syndrome associated with advanced small-cell lung cancer. Metyrapone is used in combination with systemic chemotherapy. The effects of ketoconazole and octreotide are under investigation. To control hyponatremia due to the syndrome of inappropriate antidiuretic hormone secretion, fluid restriction is standard. When hyponatremia cannot be controlled with fluid restriction, demeclocycline can be used. For life-threatening hyponatremia, hypertonic saline with intravenous furosemide is administered under careful monitoring. Followed by hydration with saline, pamidronate is effective for the control of symptomatic hypercalcemia. Combined use of calcitonin facilitates rapid normalization of serum calcium for critically ill cases. Heparin is used for patients with recurrent episodes of thrombosis resulting from chronic disseminated intravascular coagulation, although the efficacy is controversial. Thrombocytes and coagulation factors are combined with heparin for patients with uncontrollable bleeding, although the efficacy is not established.

A 24-year-old-woman was admitted because of disseminated intravascular coagulation (DIC), menometrorrhagia and galactorrhea. The investigations performed showed a right adnexal tumor after the equilibration of DIC with plasma substitution, we performed a right adnexectomy with limited excision of peritoneal. The pathologic examination showed a focus of endometriosis on the right ovary who had a polycystic look and a right adnexal fibromyxoma (premalignant lesion). The post operative evolution was good, with the loss of entire onco-hemato-endocrinologic picture. We describe the interrelation between DIC (paraneoplastic syndrome), menometrorrhagia and galactorrhea, the pathologic hypothesis and the treatment of DIC.

Acquired Glanzmann's thrombasthenia is an uncommon event in association with leukemia. The authors describe a patient with acute lymphoblastic leukemia (ALL) who presented with severe hemorrhagic syndrome, without disseminated intravascular coagulation. The patient's course was complicated by the occurrence of severe hemorrhagic episodes, with a thrombasthenia-like profile, requiring multiple transfusions with packed red cells, platelets, and fresh-frozen plasma. Biological explorations detected anti-GPIIb/IIIa complex antibodies. The patient finally died with refractory disease and persistent bleeding. This case is the first reported of autoantibodies to GPIIb/IIIa in ALL. Such paraneoplastic syndrome is potentially responsible for severe life-threatening hemorrhage.

A 49-year-old woman was admitted to our hospital because of fever of unknown origin. The patient had long-lasting spiking fever, hepatosplenomegaly, pleural effusion, and skin rash. Laboratory tests showed marked leukocytosis and an extremely high serum ferritin level (240 000 ng/ml) accompanied by disseminated intravascular coagulation and hemophagocytic syndrome. Most of the patient's features were compatible with a diagnosis of adult-onset Still's disease (AOSD), the rash, however, was not a typical rheumatoid rash but multiforme erythema. Biopsy of a breast nodule revealed breast cancer, leading us to a diagnosis of paraneoplastic syndrome mimicking AOSD. Although this is a rare disorder, cases resembling the present one have been reported, indicating the importance of including paraneoplastic syndrome in the differential diagnosis of AOSD.

Disorders of haemostasis and haemocoagulation are often seen in patients with cancer as a part of paraneoplastic syndrome. Thrombotic and/or haemorrhagic complications are the second most common cause of mortality in patients with cancer. The evaluation of the haemostatic parameters of 67 patients with gastric cancer have indicated tendency to thrombophilia and activation of intravascular coagulation, of which 31.3% showed tendency to hypercoagulation and 47.8% disseminated intravascular coagulation (DIC). Only 7.5% of subjects have yielded normal laboratory findings while 5.9% of patients had DIC with remarkable hypocoagulation. Thrombocytosis, platelet hyperaggregability and elevation of beta-thromboglobulin are the indicators of changes in primary haemostasis and elevation of thrombomodulin indicates vascular wall damage. Lower antithrombin III levels, C-protein and S-protein in plasma have indicated lower antithrombotic potential in patients with gastric cancer. It can be concluded that patients suffering from gastric cancer are at higher risk of thromboembolism as for haemorrhagic diathesis (20.1% thromboembolism, 11.94% fatal thromboembolic events vs 5.9 % haemorrhagic diathesis) (Tab. 5, Ref. 22).

Cancer-related microangiopathic hemolytic anemia (CR-MAHA) is a paraneoplastic syndrome characterized by Coombs-negative hemolytic anemia with schistocytes and thrombocytopenia. We reviewed and analyzed all cases of CR-MAHA reported since 1979 (the time of the last published review on this topic) according to predefined criteria. We found 154 cases associated with solid cancer and 14 with lymphoma. Among the solid cancers, gastric, breast, prostate, lung, and cancer of unknown primary (CUP) were most common; 91.8% of cancers were metastatic, and in 19.4% of solid cancers CR-MAHA did not occur until recurrence of cancer. Lymphoma cases included Hodgkin disease, angiotropic lymphoma, diffuse large cell lymphoma, and myeloma. Evaluation of the clinical and laboratory findings revealed that only a minority of cases presented with the features of thrombotic thrombocytopenic purpura (TTP) or atypical hemolytic uremic syndrome (aHUS), with the exception of prostate cancer, where aHUS was a common presentation. Compared to hereditary or immune TTP or aHUS, disseminated intravascular coagulation and pulmonary symptoms were more common in CR-MAHA. Plasma exchange or fresh frozen plasma was rarely effective except in prostate cancer patients with aHUS. CR-MAHA responded to antitumor therapy in many patients with gastric, breast, lung, and CUP cancers. These patients had a superior survival compared to patients without chemotherapy. Compared to the prognosis of patients with metastatic cancer without CR-MAHA, the prognosis of CR-MAHA patients was greatly inferior. There is evidence that some cases of CR-MAHA in lymphoma are immune mediated.
