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 case of nontraumatic chronic subdural hematoma due to obstruction of dural vessels by tumor cells is presented and 25 reported cases are reviewed. A 39-year-old female was referred for headache, vomiting, disturbance of consciousness and right homonymous hemianopia with macular sparing. She had undergone mammectomy for medullary nodular carcinoma of the left breast five years before. She had been treated with combined hormonal therapy and chemotherapy for the cancer metastases to the liver in preceeding six months. Hematological examination revealed drug-induced thrombocytopenia, increase of FDP in blood (80 micrograms/ml), but no abnormality of prothrombin time and fibrinogen content. Therefore in the present case there was no evidence of disseminated intravascular coagulation (DIC) after Colman's criteria. However, it was suggested that this case had compensated DIC after Cooper's criteria. CT scan showed a biconvex-shaped low and partially iso-density area over the left fronto-temporal convexity, indicative of chronic subdural hematoma, and no abnormal findings in the occipital area. After removal of the hematoma she became alert without headache and vomiting. However, seven days later she complained of headache and vomiting again. Repeated CT scan showed a larger biconvex-shaped low density area over the left hemisphere extending to the parietal region at that time. Second operation was performed, but she expired four days later. Autopsy showed systemic metastases of the medullary nodular carcinoma in the scalp, temporal muscle and dura as well as lungs, adrenal glands, ovaries and bone marrow.(ABSTRACT TRUNCATED AT 250 WORDS)

The cases of two patients suffering from carcinoma of the lung and severe thrombocytopenia are described. The thrombocytopenia was probably due to an immune mechanism and not to marrow replacement by carcinoma or consumption coagulopathy. It is suggested that patients in the older age group presenting with thrombocytopenia may have occult carcinoma.

Carcinoma of the prostate, above all when accompanied by bone metastases, may be associated with a disseminated intravascular coagulation syndrome. The problem was to determine whether even in the absence of metastases the coagulation state of prostatic carcinoma patients predisposes them to disseminated intravascular coagulation. The authors compared coagulation equilibrium in 13 patients with a prostatic adenoma and 21 with carcinoma of the prostate free of metastases or infection. Fibrin breakdown product levels were abnormally high in 85.7 % of the carcinoma patients (as against 46.2 % of the adenoma sufferers). Clotting factor XIII was decreased in 70 % of carcinoma patients (as against 48.5 % of those with an adenoma). One prostatic carcinoma patient in four shows evidence of latent intravascular coagulation even in the absence of bone metastases. This prevalence justifies thorough coagulation studies in all patients with carcinoma of the prostate.

Five cases of recurrent cervical carcinoma with restricted recurrent site in the pelvis were treated with intra-arterial infusion of oncostatics via the internal iliac artery. The tip of the catheter was put in the internal iliac artery, just proximal to the superior glutea artery, through the a. glutea inferior or superior with ligation of both the a. glutea superior and inferior so as to get a high concentration of drugs at the lesion. Several chemotherapeutic agents, such as Cisplatin, adriamycin, pepleomycin, mitomycin C and 5-FU, were infused through the other end of the catheter, which was fixed at the subclavian fossa of the anterior chest. The clinical efficacies according to Karnofsky's criteria were 0-C in one case, 1-A in 1 case and 1-B in 3 cases. The overall response rate above 1-B was 60%. Two cases were dead, one due to inflammation in the pelvic dead space and D.I.C. and other due to myocarditis and heart failure. The other three were alive and treated with weekly intra-arterial infusion at our outpatient clinic. No troubles, such as spontaneous removal of the catheter, inflammation around the catheter or bleeding, have been encountered. The toxicities in the case of intra-arterial infusion were less prominent than in the case of intravenous administration of the same dosage of the oncostatics.

Retrospective evaluation of the state of hemostasis in 20 patients dying with pulmonary artery thromboembolism (PATE) after combined treatment of renal carcinoma (10) and urinary bladder carcinoma (10) was performed. The signs of intravascular blood coagulation (IVBC) in the initial condition were determined in all the patients. After a course of pre-operation actin therapy with large fractions (totally 20 g) activation of IVBC was observed both in renal and urinary bladder carcinoma. In the postoperation period, on the day of PATE development in patients with renal carcinoma the state of hemostasis corresponded to stage I of disseminated intravascular coagulation syndrome. In patients with urinary bladder carcinoma after operation the state of hemostasis corresponded to stage II of DIVC-syndrome with signs of local hemorrhage of the urinary bladder wound. The therapy of this condition with fibrinolysis inhibitors (aminocaproic acid) with hemotransfusion without heparin facilitated thrombus formation in these patients in deep pelvic veins followed by PATE.

Procoagulant activity of gastric cancer tissues and leukocytes obtained from various types of leukemia have been studied with special reference to TTP. The following results were obtained. Homogenates of APL leukocytes and gastric cancer tissues contained strong procoagulant activities, most of which have been identified as TTP since the activities were neutralized by a specific antibody against purified human placenta TTP, inactivated by the removal of phospholipid with heptane-butanol mixture, and inactivated by the addition of phospholipase C. The delipidated homogenates regained procoagulant activities by relipidation procedures. These results also confirmed that TTP from APL leukocytes and gastric cancer tissues have the same lipoprotein properties as those of TTP in normal tissues. Though slight proteolytic activity and fibrinolytic activity were demonstrated in the homogenate of gastric cancer tissues, it was noted that the TTP activity was different from these two activities by partial purification of TTP from gastric cancer tissues. The TTP activity of 9 homogenates of gastric cancer tissues was 301 +/- 289 (mean +/- SD) units per mg protein, being higher in homogenates of mucinous adenocarcinoma and signet-ring cell carcinoma than in those of tubular and poorly differentiated adenocarcinoma. The mean TTP activity of leukocyte homogenates from 14 patients with APL and one out of 4 patients with CML in blastic crisis was 81 +/- 76 units/10(7) cells. The TTP activity of the homogenates of leukocytes from 7 out of 18 patients with AML and another patient with CML in blastic crisis ranged from one to six units/10(7) cells with a mean of 3.3 +/- 1.2. The TTP activity of leukocyte homogenates from the other 11 cases of AML, two cases of CML in blastic crisis, 6 cases of CML, and one case each of ALL and CLL were less than one unit/10(7) cells. In leukemic patients, all cases with a value of more than 202 for the product of units of TTP activity per 10(7) cells and differential count (%) of leukemic cells in the bone marrow smear (MU value) were accompanied by DIC. The MU value of leukemic patients correlated well to the plasma fibrinogen and serum FDP levels. All patients with a MU value of more than 277 died of DIC when a sufficient amount of heparin was not administered. On the other hand, no DIC developed in any of the patients with a MU value of less than 90.(ABSTRACT TRUNCATED AT 400 WORDS)

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.

Five cases of intracranial hematoma secondary to chronic disseminated intravascular coagulation syndrome (DIC) were reported. Intracranial hematomas included a case of acute subdural hematoma combined with intracerebral hematoma and 4 cases of acute or subacute hematoma. Primary diseases which caused DIC were cancer; a case of carcinoma of choledochus and 4 cases of gastric carcinoma. All cases were in the advanced stage of carcinoma or at least, had metastasis to other organs. They showed coagulation disorders, such as, the reduction of platelets and the hemorrhagic diastasis, which were referred as chronic DIC, before the onset of intracranial hematoma. After the onset of intracranial hematoma, their coagulation disorders got worse and were diagnosed as acute DIC. They showed the rising of FDP, reduction of the serum fibrinogen and platelets and others. The blood transfusion and the trivial head injury were considered a triggers of exacervation from chronic DIC to acute DIC, that is, from compensated DIC to decompensated DIC. The long-term administration of anticancer drugs might play a part of the role as triggers. Initial symptoms of intracranial hematoma were headache in 4 case and dullness in a case. Three cases immediately lapsed into coma after 1 to 2 hours from the onset. Two cases turned out coma state after 4 to 5 days from the onset. Evacuations of hematoma were performed in 3 cases but they gave rise to rebleeding of intracranial hematomas later. All of 5 cases including surgically and non-surgically treated cases died at last. It is certain that DIC is rather common in the advanced stage of cancer. Matsuda reported that DIC existed in 20% of died patients with cancer. Though the incidence of intracranial hematoma secondary to DIC were less than that of cerebral infarct, it is no reasonable to assume that the actual number of the intracranial hematoma secondary to chronic DIC is rare.
