1/86. disseminated intravascular coagulation.OBJECTIVES: To provide an overview of the pathophysiology, manifestations, diagnosis, and treatment of disseminated intravascular coagulation (DIC) as it occurs in cancer. DATA SOURCES: Published articles, research reports, and book chapters. CONCLUSIONS: The syndrome of DIC is a serious hypercoagulation state that in its acute form may be life-threatening. The hemorrhage and intravascular coagulation that occur with DIC may lead to irreversible morbidity and mortality. Prompt recognition and emergency treatment are necessary to help minimize morbidity and mortality. IMPLICATIONS FOR NURSING PRACTICE: nurses can play an important role in early recognition of DIC to allow for prompt intervention. nurses caring for patients affected by DIC will be providing complex nursing care, in addition to psychosocial support to patients and families.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
2/86. disseminated intravascular coagulation in a patient treated with strontium-89 for metastatic carcinoma of the prostate.strontium-89 is effective in the palliation of bone pain caused by skeletal metastases. Its primary side effect is mild thrombocytopenia that typically recovers in 3 or 4 months. Subclinical disseminated intravascular coagulation is reported to be present in approximately 10% to 20% of patients with advanced prostate cancer. These patients may be at increased risk for severe marrow depression after radionuclide therapy for bone pain palliation. This report describes a patient with painful bony metastases resulting from prostate carcinoma. He had a normal platelet count and no clinical evidence of a coagulation disorder at the time of strontium-89 therapy, and a severe disseminated intravascular coagulation developed and lead to death after treatment. A normal platelet count before strontium-89 therapy does not preclude subsequent disseminated intravascular coagulation, and we support the Society of nuclear medicine's bone pain treatment procedure guideline that patients referred for bone palliation should be screened for disseminated intravascular coagulation before therapy.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
3/86. Purulent pericarditis due to group B streptococcus and mycotic aneurysm of the ascending aorta: case report.A 61-year-old female, with a history of uterine and cervical cancer treated with radical hysterectomy and 2 years of postoperative chemotherapy, presented to the emergency department with dyspnea on exertion. Computed tomography of the chest revealed a large pericardial effusion and a sacciform aneurysm of the ascending aorta. The patient subsequently underwent emergency pericardiocentesis with drainage of approximately 330 ml of a bloody and turbid effusion. Cultures from the effusion yielded group B streptococcus. multiple organ failure and disseminated intravascular coagulation syndrome occurred in the acute phase, but gradually improved with continuous antibiotic therapy. On the 194th hospital day, in situ reconstruction of the ascending aorta was successfully performed using a synthetic graft. Although rarely reported, both purulent bacterial pericarditis and mycotic aneurysm can be life-threatening.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
4/86. Intramedullary spinal cord metastasis from gastric cancer. Case report.A case of intramedullary spinal cord metastasis from gastric cancer is reported. A 51-year-old woman presented with hemicord syndrome that had progressed within 1 month to tetraplegia. Despite total resection of the tumor, she died of disseminated intravascular coagulation and multiple organ failure. Examination of pathological findings demonstrated undifferentiated adenocarcinoma, and postoperative gastroendoscopic study revealed advanced gastric cancer. To the authors' knowledge this is the first case of intramedullary spinal cord metastasis from gastric cancer. The clinical characteristics of the disease are discussed.- - - - - - - - - - ranking = 7keywords = cancer (Clic here for more details about this article) |

6/86. Microvascular endothelial abnormality in skeletal muscle from a patient with gastric cancer without dermatomyositis.We found a microvascular endothelial abnormality in a biopsy specimen from the gastrocnemius muscle of a patient with gastric cancer, who had severe myalgia and angialgia in the calf region with the symptoms of thrombophlebitis. There were no definite findings of inflammatory myopathy in histochemical and immunohistochemical studies. Electron microscopic examination revealed the accumulation of abnormal mitochondria in the subsarcolemmal area, and a fair number of degenerating capillaries. Immunohistochemical analysis of procoagulant or anticoagulant factors revealed marked reduction of thrombomodulin (TM) expression on small vessels and capillaries. Although a reduction of TM on small vessels has been observed around perifascicular atrophic fibers in patients with dermatomyositis, histochemical findings of the present patient showed no perifascicular atrophy or severely degenerating fibers. These pathological findings in the patient may be related to a malignant neoplasm and may be one of the causes of disseminated intravascular coagulation (DIC), which is the main complication of malignant neoplasms. Further studies are necessary to determine whether the reduction of TM on the small vessels and capillaries in skeletal muscle is a predictor of some severe condition such as DIC or a rare pathological finding in some special condition such as scirrhous carcinoma with thrombophlebitis.- - - - - - - - - - ranking = 5.4243844322484keywords = cancer, muscle, neoplasm (Clic here for more details about this article) |
7/86. disseminated intravascular coagulation in a lung cancer patient after acute myocardial infarction.A 70-year-old man with adenocarcinoma of the lung suffered from an attack of acute myocardial infarction during hospitalization. Eleven days after the heart attack, clinically obvious disseminated intravascular coagulation (DIC) occurred. The intravascular coagulation abnormalities progressed and eventually the patient died. We suspect that both lung adenocarcinoma and the insult of myocardial infarction may have contributed to the development of DIC in this patient.- - - - - - - - - - ranking = 4keywords = cancer (Clic here for more details about this article) |
8/86. Increased warfarin sensitivity as an early manifestation of occult prostate cancer with chronic disseminated intravascular coagulation.Increased sensitivity to warfarin anticoagulation is usually attributed to liver disease, vitamin k deficiency, or drug interactions. We describe a patient with unexplained sensitivity to warfarin and mildly elevated prostate-specific antigen levels in whom subsequent developments indicated that warfarin sensitivity was the first manifestation of occult prostatic cancer. A review of all published cases of coagulopathy associated with cancer of the prostate shows that, unlike other solid tumors with secondary disseminated intravascular coagulation (DIC), in prostate cancer increased bleeding is more common than thrombotic phenomena. Chronic DIC due to occult prostate cancer should be included in the differential diagnosis of excessive prothrombin time prolongation in patients receiving anticoagulants.- - - - - - - - - - ranking = 8keywords = cancer (Clic here for more details about this article) |
9/86. disseminated intravascular coagulation associated with intratumoral hemorrhage of ovarian cancer.BACKGROUND: Ovarian carcinoma usually presents in an indolent manner. A patient with ovarian cancer rarely shows acute clinical features which require immediate medical intervention. CASE: We present a 36-year-old Japanese woman with an ovarian tumor, who suffered general fatigue and increased abdominal girth on admission. Her hemoglobin, platelet count and fibrinogen were decreased, and fibrin/fibrinogen degradation products were elevated, which determined the diagnosis of disseminated intravascular coagulation (DIC). Since computed tomography scan and magnetic resonance imaging revealed an intratumoral hemorrhage, an emergency laparotomy was performed. The patient was found to have ovarian cancer with a massive intratumoral hemorrhage, and DIC improved immediately after the operation. CONCLUSION: The clinician should be alert to the possibility that intratumoral bleeding of ovarian cancer might be associated with DIC.- - - - - - - - - - ranking = 7keywords = cancer (Clic here for more details about this article) |
10/86. disseminated intravascular coagulation and PC-SPES: a case report and literature review.BACKGROUND: PC-SPES is a herbal remedy gaining acceptance amongst prostate cancer patients and health care providers due to credible laboratory and clinical studies. However, PC-SPES has not been assessed in the standard rigorous approval process mandated for conventional agents. OBJECTIVES: To present a case of a patient with prostate cancer who, while using PC-SPES, developed disseminated intravascular coagulation (DIC). A review of the literature was conducted to determine if there is a relationship between PC-SPES and hemorrhagic disorders. methods: Searches were conducted in medline (1966-December 2000) and the Cochrane Collaboration's database. RESULTS: There are 116 clinical and laboratory based studies of PC-SPES published to date. There are no randomized controlled trials. Clinical studies have demonstrated a significant reduction in prostate specific antigen (PSA) levels within 6 weeks. Improved quality-of-life, reduction in the volume of tumor deposits and reduction in analgesic use has been demonstrated in hormone refractory patients. Laboratory studies suggest that the beneficial effects of PC-SPES are unrelated to physiologic estrogens. However, PC-SPES has a side-effect profile similar to diethylstilbestrol. There is data demonstrating a <5% risk of thromboembolic events, but this is the first report of DIC. CONCLUSION: The study of PC-SPES is in its infancy. This case may serve as a cautionary note to health care providers and patients regarding herbal remedies. Those using PC-SPES should have an increased level of surveillance for bleeding disorders.- - - - - - - - - - ranking = 2keywords = cancer (Clic here for more details about this article) |
