DIC may complicate prostatic disease either in its acute type during resection of the prostate causing excessive intra- or postoperative bleeding, or in its chronic type in cases with adenocarcinoma of the prostate with haematogenous metastases. Pathogenesis, diagnosis, clinical course, differentiation of the condition against consumption of clotting factors by primary fibrinolysis, and treatment are discussed. The course in four characteristic cases is demonstrated.

This study assess the effects of oral BCG, as a single agent, on tumor progression and on cell-mediated immune function in patients with metastatic malignant melanoma. Thirty patients were studied including 22 with measurable metastatic lesions and 8 with no detectable disease, following treatment of metastases by surgery, radiotherapy, or 5-(3, 3-dimethyl-1 -triazeno)-imidazole-4-carboxamide (DTIC; DIC). Oral BCG was given in doses of 120--240 mg, 1--3 times per week for periods ranging from 9 to 80 weeks and to total doses of from 1.2 to 20.1 gm. Patients were assessed by direct measurements of tumor mass, PPD skin test and in vitro blastogenic responses to PPD PHA. Of the 22 patient with measureable disease, 19 showed tumor progression and none showed regression of any lesion. Of the 8 without apparent disease, 5 remained stable and 3 had tumor recurrence. Of the total group of 30 patients, 8 showed some increased sensitivity to skin testing with PPD. Of 19 tested, 3 showed an increased PPD response in vitro, while 3 showed a decreased response. Six of 20 tested showed an increased PHA response in vitro. Oral BCG alone was not effective as an antitumor agent in patients with metastatic malignant melanoma.

Hemostatic abnormalities are present in a majority of patients with metastatic cancer. These abnormalities can be categorized as 1) increased platelet aggregation and activation, 2) abnormal activation of coagulation cascade, 3) release of plasminogen activator, and 4) decreased hepatic synthesis of anticoagulant proteins like Protein C and antithrombin III. The abnormal activation of coagulation cascade is mediated through release of Tissue Factor, Factor X activators, and other miscellaneous procoagulants from the plasma membrane vesicles of tumor cells. Macrophages of a tumor-bearing host also produce increased amounts of Tissue Factor. Production of Factor X activators and macrophage Tissue Factor is decreased by warfarin. The ability of the tumor cells to produce platelet-aggregating activity and plasminogen activator parallels their metastatic potential in animal and experimental systems. These studies also show that antiplatelet agents and antibodies against plasminogen activator can suppress the metastatic process. One or more laboratory abnormalities of hemostasis can be shown in up to 95% of patients with metastatic cancer. These abnormalities, however, are unable to predict subsequent development of thromboembolic or hemorrhagic complications. Clinical complications occur in 9-15% of the patients in the form of thrombotic or hemorrhagic disorders. The therapy of tumor-related coagulopathy should be guided by its clinical expression. Subclinical DIC should not be treated. Coumadin is generally ineffective for therapy of thrombosis in cancer patients. There is no consensus regarding the use of heparin in acute promyelocytic leukemia (APL). The defibrination in APL may be from disseminated intravascular coagulation as well as systemic fibrinolysis, as shown by decreased alpha 2 antiplasmin levels. In such cases, epsilon aminocaproic acid plus heparin therapy may be of benefit.

Twelve autopsy cases of carcinomatosis of the bone marrow were examined clinicopathologically. Among them, 7 were gastric adenocarcinoma, and the other 5 were a rectal carcinoid and carcinomas of the lung, prostate, maxilla and kidney, respectively. The gastric cancers were almost all poorly differentiated adenocarcinoma with mucin production and presented poorer prognoses than the other cancers. Leukoerythroblastic anemia, microangiopathic hemolytic anemia and DIC were found more frequently in the gastric cancers than in the others. It is concluded that the evolution of these critical hematologic disorders may be dependent on differences of histologic type, original focus and cancer-host interactions as well as wide-spread skeletal metastases of cancer cells.

A case of malignant fibrous histiocytoma (MFH) occurring in th retroperitoneum with giant pyonephrosis is reported. The patient was a 45-year-old male and his chief complaint was an abdominal mass. The abdominal fullness progressed so rapidly that he was admitted to our hospital. After examination, this case was diagnosed as a malignant tumor with left hydronephrosis, and an operation was performed on August 5, 1982. At operation, the left kidney contained about 11,000 ml of a pus-like fluid and in the retroperitoneum was found a hen-egg-sized solid tumor which was invading into the left kidney and the feeding vessels of the descending colon. So the tumor, left kidney and a part of the descending colon were resected en bloc. Pathological diagnosis was malignant fibrous histiocytoma. Chemotherapy (PPM regimen) and immunotherapy (OK-432) were administered after the operation, but multiple metastases appeared in the liver and bilateral lungs within 3 months. Then, the CY-VA-DIC regimen was followed. But, local recurrence was found in about 5 months, and the patient died on the 174 th day after the operation. Local recurrence and metastases in the liver, bilateral lungs, pleura and bones were confirmed at autopsy. Besides our case, a review of case reports of retroperitoneal MFH in Japan and comments are presented.

Hematologic alterations unrelated to neoplastic bone marrow involvement include polycythemia, anemia, leukocytosis, leukopenia, thrombocytosis, thrombocytopenia and coagulopathies. Serum globulin levels may be increased or decreased, depending on the type of neoplasm. Plasma fibrinogen and fibrin degradation product concentrations are usually elevated in cancer patients, whereas cancer patients with DIC have low plasma fibrinogen concentrations. Hypercalcemia can be a sequel of osseous metastases. Neoplasia may cause the nephrotic syndrome in some patients. Effusions should be examined microscopically for signs of malignancy. Elevated serum enzyme levels are not specific in neoplastic disease.

The purpose of this study was to detect possible factors related to the occurrence of DIC in carcinoma patients. I) We studied 20 carcinoma cases accompanied with DIC. Results; The carcinomas most frequently accompanied with DIC were cancers of the biliary system, gastric, hepatic and pancreatic cancer, especially those with distant metastases. Pneumonia, UTI and biliary tract infections seemed to be the most important triggers of DIC. No significant relationship was found between anti-cancer chemotherapy and the DIC incidence. Endotoxemia was more frequently detected in patients having received anti-cancer drugs than in those who not. II) The effects of anti-cancer chemotherapy on the incidence of endotoxemia was examined in rats. A higher incidence of endotoxemia was noted in the groups treated with high doses of 5-FU or Cyclophosphamide. The incidence of endotoxemia seemed to run parallel with the incidence of diarrhea and of weight loss in each animal group.

A case of paraneoplastic DIC syndrome (asymptomatic carcinoma of the gastric fundus with multiple metastases) is described. Initially, differential diagnosis hesitated before thrombotic thrombocytopenic purpura (Moschowitz' syndrome), given the presence of grave microangiopathic haemolytic anaemia as a major symptom. The main characteristics of Moschowitz' syndrome and the most frequent causes of DIC are described in the discussion.

In 40 patients with non-metastasising (n = 31) and metastasising (n = 9) renal cell carcinoma, evidence of Stauffer's syndrome (increase in alkaline serum phosphatase and prolongation of prothrombin time) was found in 18 patients. Prolongation of prothrombin time was not due to depletion of vitamin K-dependent coagulation factors or manifest fibrinolysis, but due to the presence of circulating fibrinogen fibrinmonomer-FDP complexes. Ethanol gelation test was found to be positive in 28/40 subjects and soluble fibrin monomer complexes were increased in 38/40 patients. The resulting disturbance of fibrinogen-fibrin conversion was reflected by an increase in thrombin coagulase time and reptilase time. These findings suggests a state of latent compensated intravascular coagulation (presumably triggered within the vascular tumor). For diagnostic purposes the most sensitive indicator is thrombin coagulase time. Thrombin coagulase time normalised after tumor resection and was positive in patients with recurrent metastases. The increase in alkaline serum phosphatase was due to an increase in the hepatic isoenzyme. Such an increase was much more common than the elevation of total alkaline serum phosphatase. Regan's isoenzyme was only found in 1 subject. In parallel, gamma-GT was elevated in 24 patients. The study shows that Stauffer's syndrome occurs more frequently than commonly assumed when thrombin coagulase time, gamma-GT and the hepatic isoenzyme of alkaline serum phosphatase are determined in patients with renal cell carcinoma. DIC and low grade fibrinolysis may account for the coagulation abnormalities of the syndrome.

In 124 patients with various types of malignancy, fpA and delta fpA were measured. In 35 of these patients the effect of heparin injection on fpA and delta fpA was studied. All patients were ambulant without clinical signs of venous thromboembolism or DIC and had not received cytostatic, anticoagulant, or radiotherapy recently. In about 75% of these patients, fpA was elevated, whereas in the blood of one third of the patients, both elevated fpA levels and accelerated delta fpA were detected. Eight of the 45 patients with accelerated delta fpA (and elevated fpA) presented laboratory signs of low-grade DIC. In the patients taken at random for heparin administration, delta fpA normalized upon heparin injection, whereas in the majority of patients, irrespective of the fpA-generation rate, fpA levels were not affected by "adequate" heparinization. These results indicate that (1) about 30% of the (selected) patients admitted to our cancer clinic present with evidence of intravascular thrombin activity and (2) in 70% of these patients fpA is generated, at least in part, at a site not accessible to heparin. In addition 95% of patients with active metastatic disease showed an elevated fpA, whereas 90% of cancer patients in remission and 80% of patients without metastasis had a normal fpA, indicating that fpA can potentially be used to estimate the spread and the activity of the malignant process.
