Of 1,048 renal transplants performed between 1971 and 1990, transplant nephrectomy was performed in 86 (8.2%). Mean patient age was 33 years (range 3.8 to 66.5). Postoperative complications occurred in 60% of the patients, including wound infection in 20% and major hemorrhage in 4 patients. The external iliac artery was ligated in 4 patients. The incidence and severity of the complications were greater in patients with acute rejection. Four patients died: 1 of ischemic bowel and metastatic carcinoma, 1 of pulmonary embolism, and 2 of sepsis and disseminated intravascular coagulation. The nephrectomy rate increased significantly (p < 0.005) when cyclosporine A was initially introduced. Added care is necessary when new immunosuppressants are used. The majority of our failed transplants were left in situ without compromising overall patient well-being.

An autopsy case of portal systemic encephalopathy and senile dementia of the Alzheimer type coexisting in a 77-year-old man is described. The patient had suffered recurrent episodes of delirium after a subtotal gastrectomy for gastric carcinoma. He died of DIC 45 months after the gastrectomy. A pathological examination revealed a vascular plexus around the liver which might have served as collateral circulation. Neuropathologically, spongy necrosis and Alzheimer type II changes of astrocytes were found in the basal ganglia and fronto-occipital cortices. In the same anatomical regions, only immunohistological staining using antibody against amyloid beta-protein and the periodic-acid methenamine silver method revealed abundant neuriticplaques, cerebral amyloid angiopathy and diffuse plaques. We discussed the clinicopathological findings in this case.

The mitomycin antibiotics, because of their preferential toxicities for hypoxic cells, have significant potential as adjuncts to ionizing radiation in the treatment of solid tumors. To gain information on the mechanism by which these agents exert their cytotoxicities to hypoxic and aerobic cells, the effects of MC, POR and several of their analogs were studied in EMT6 mammary carcinoma cells. The rate of uptake of POR by these cells was directly correlated with the cytotoxicity produced by this agent under both hypoxia and aeration. At equivalent concentrations, uptake of POR into hypoxic cells was more rapid than into aerobic cells. Hypoxic cells also accumulated the antibiotic in concentrations well in excess of that present in the extracellular medium, presumably as a result of reductive activation and covalent binding of POR to cellular structures. Such activation and binding occur to a much lesser degree in aerated cells, resulting in the rapid efflux of POR from these cells when the antibiotic is removed from the extracellular environment. To gain information on the reaction of POR with DNA, mono- and bis-adducts formed in EMT6 cells exposed to this agent were measured. Three major adducts were formed. Two were mono-adducts consisting of deoxyguanosine linked at its N2-position to the C-1 of POR and of 10-decarbamoyl POR. The third was a bis-adduct in which POR was cross-linked to two deoxyguanosines at their N2-positions. More adducts were formed in hypoxia than in air, and more bis-adducts were present in hypoxic cells. Simultaneous exposure of cells to both POR and DIC reduced the total adduct level and a new unknown adduct was formed, primarily under hypoxia. Several mitomycins were evaluated for their capacity to kill EMT6 cells and to produce DNA cross-links in both hypoxia and aeration. The number of cross-links required to produce a given amount of cell kill was similar, regardless of the mitomycin employed or the degree of oxygenation. The findings support the concept that DNA is a critical target in the action of the mitomycins and that cross-linking of the DNA creates an important lesion for cytodestruction.

More and more physicians are finding increasing evidence of carcinoma-related immune-mediated platelet destruction. Such is the case of the patient with carcinoma of the exocrine pancreas associated with profound thrombocytopenia that follows. The patient died before studies could be completed. However, well-recognized causes of drug reactions, DIC, chemotherapy and marrow infiltration were able to be excluded. Although anti-platelet antibodies weren't isolated in the serum, the patient's response to steroids and its similarity to other cases with evidence of carcinoma-related immune-mediated platelet destruction makes this process most likely in the case presented.

We reported on a 74 year old patients with local advanced prostatic carcinoma. Following prostatic surgery an increased bleeding tendency was observed. The patients showed clinical and laboratory evidence for consumption coagulopathy with hyperfibrinolysis. The laboratory data were: marked decrease of AT III, Protein C, increase of thrombin/AT III complex level, fibrin degradation products (FDP) and antigen of t-PA. The treatment was ended successful.

We present a case of very late and unusual recurrence of gastric cancer. Nine years following total gastrectomy for gastric carcinoma, a 57-year-old man presented with disseminated intravascular coagulation associated with bone marrow recurrence. The primary tumor was a signet ring cell carcinoma invading the subserosal layer with lymph node metastasis. The patient was treated with sequential administration of methotrexate and 5-fluorouracil and went into remission. After treatment, he survived 10 months. Autopsy revealed diffuse bone marrow infiltration and distant lymph node metastasis with signet ring carcinoma cells.

We found 5 cases of prostatic carcinoma with metastasis with alpha 2 macroglobulin (alpha 2 M) concentration below approximately 40 mg/dl in serum. All these patients had bone metastasis, and none of them had DIC. We found no other cases with such a low concentration of alpha 2 M. Their alpha 2 M level increased to normal level after treatment with transurethral resection of prostate or hormone agents, and the level was correlated with the clinical symptom. During the clinical course, their alpha 2 M level was negatively correlated with prostate-specific antigen (PSA) and prostatic acid phosphate (PAP). All these results suggest that alpha 2 M concentration in serum reflects the severity of prostatic carcinoma with metastasis and that alpha 2 M deficiency is an indicator of metastasis. The acute phase proteins of CRP and serum amyloid A did not increase in spite of the presence of metastasis in these patients with extremely low alpha 2 M level (< 20 mg/dl), suggesting that alpha 2 M is involved in the metabolism of these acute phase proteins. On immunohistochemical studies, their specimens of prostatic carcinoma gave positive stain for PSA and urokinase-type plasminogen activator (u-PA). Both PSA and u-PA formed a complex with alpha 2 M in vitro. The alpha 2 M deficiency in these patients might be due to the complex formation between alpha 2 M and these prostate-originated proteases and to the rapid disappearance of the complex.

During activation of the fibrinolytic system plasminogen is converted to plasmin by tissue plasminogen activator (t-PA) or urokinase-type plasminogen activator (u-PA). t-PA is predominantly released from endothelial cells, u-PA primarily by renal parenchymal cells. The activation of plasminogen is regulated by plasminogen activator inhibitor-1 (PAI-1), plasmin is controlled by alpha 2-plasmin inhibitor. The fibrinolytic system is not only involved in the intravascular dissolution of fibrin (thrombi), it also plays a vital role in normal physiologic reproduction, wound repair, angiogenesis, and tissue remodeling. Fibrinolysis is also a vital component in the pathogenesis of neoplastic disease. It is essential in releasing cells from their primary site of origin, providing nutrition for neoplastic cell growth and promoting cell mobility and motility. In neoplastic cells the degradation of the extracellular matrix proteins is facilitated by excessive expression of u-PA, t-PA, and u-PAR. In many forms of carcinoma increased expression of u-PAR and u-PA is associated with significantly shorter survival. Greater expression of u-PA in breast cancer cells, for example, is associated with shorter survival and increased relapse rate. Progressively aggressive neoplastic cells evidence high expression of u-PA and u-PAR activities, variable expression of t-PA, and enhanced PAI-1 and PAI-2 activities. In acute nonlymphocytic leukemias, poor outcome correlates with high t-PA levels. In acute progranulocytic leukemia there is a high incidence of DIC. Neoplastic prostatic tissue also expresses high u-PA activity and the more aggressive the cell line, the greater the number of u-PAR and the higher the u-PA activity. In gynecologic malignancies, a greater expression of u-PA in combination with cathepsin D is associated with widespread disease and poor prognosis. High u-PA values were also seen in patients with brain, gastric, and hepatic malignancies. It is evident that the plasminogen-plasmin system is a vital component in the biology of neoplastic disease and that it is, in theses conditions, in no way beneficial to the host.

Under study were the state of the hemostasis system, the level of endogenous intoxication and anti-infectional defense in 63 patients with complicated carcinoma of the gastro-intestinal tract (GIT). It was established that the patients had the syndrome of disseminated intravascular coagulation (DIC) of blood which at first was of local character. Acute complications of carcinoma of GIT, first of all purulent peritonitis and profuse gastro-intestinal bleedings, aggravate endotoxicosis and facilitate the development of the acute DIC syndrome. A conception of the development of the intoxicative DIC syndrome is presented and proposed are informative methods of the assessment of hemostasis in emergency surgery of carcinoma of the GIT.

The authors estimate results of correction of the hemostasis system in surgical treatment of 63 patients with complicated carcinoma of the gastro-intestinal tract. It was found that purulent peritonitis, profuse hemorrhage and obturative obstruction facilitated the development of local and generalized DIC syndrome. Methods of correction of the hemostasis system, endogenous intoxication during preoperative preparing are described. Expedience of radical operations is stressed. Complex postoperative detoxication is recommended as well as measures for the restoration of activity of the vascular-thrombocytic hemostasis and prevention of thrombus formation.
