A juxtaovarian tumor of probable mesonephric origin in an 18-year-old white woman recurred six years later with a pelvic mass and widespread peritoneal metastases. Chemotherapy with cyclophosphamide, Doxorubicin, and cis-platinum induced a partial response of approximately one year duration. The terminal disease course was associated with hypercalcemia and disseminated intravascular coagulation. At autopsy, there were extensive abdominopelvic tumor masses with pleural deposits.

Microangiopathic hemolytic anemia and thrombocytopenia secondary to disseminated intravascular coagulation is a well-described complication of widely metastatic carcinoma. The authors report four cases of gastric carcinoma, one case of colon cancer, and one case of adenocarcinoma of unknown primary in which the patient developed a syndrome analogous to thrombotic thrombocytopenic purpura, consisting of microangiopathic hemolytic anemia, thrombocytopenia, and renal failure without definite evidence of disseminated intravascular coagulation. In contrast to previous reports, postmortem examination in three of the cases revealed no recurrence or only microscopic foci of residual tumor. In the remaining three, there was clinical and pathologic evidence of grossly disseminated carcinoma. Also in contrast to previous cases, all patients evidenced azotemia and proteinuria at the onset of the syndrome and ultimately uremia was a contributing cause of death. Coagulation profiles showed prolonged thrombin times and elevated fibrin degradation products in four instances and did not distinguish the patients with grossly metastatic disease from those with no tumor or only microscopic residua. Circulating immune complexes containing carcinoembryonic antigen were found in the patient with metastatic colon carcinoma. The syndrome was clinically identical whether or not grossly metastatic tumor was present, and it should not be attributed to advanced disease without definite clinical or pathologic evidence of a recurrence.

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.

We performed coagulation profiles including a complete blood count (CBC), prothrombin time (PT), activated partial thromboplastin time (aPTT), and quantitation of fibrinogen, antithrombin III (AT III), plasminogen, and fibrin/fibrinogen degradation products (FDP) on 73 cancer patients. All had solid tumors with clinically documented metastases. Eleven patients had strong clinical and laboratory evidence of disseminated intravascular coagulation (DIC). Fifty-five of the remaining 62 patients had no clinical evidence of serious hemorrhage or thrombosis at the time of testing. Thirty-one (50%) non-DIC patients had no abnormal clotting tests. Our data indicate that a majority of cancer patients, with or without hepatic involvement, are able to maintain normal or near normal hemostatic function in vitro until advanced stage of disease. Deviation from normal for PT, aPTT, or TT, depressed AT III activity, or increased FDP signal the presence of complicating pathophysiologic events such as DIC or cirrhosis. Diminution of fibrinogen level or AT III activity and elevation of FDP are more sensitive indicators of DIC than prolongation of PT, aPTT, or TT.

The long-acting synthetic somatostatin analog, SMA 201-995, was used to treat patients with advanced hormonal-refractory prostate cancer. Twenty-two of 24 study patients treated are evaluable for toxicity and 20 are evaluable for response. The dose of SMS 201-995 was 100 mg subcutaneously every 8 hours for 6 weeks. Two patients suffered intolerable gastrointestinal complications requiring early cessation of therapy. No patient had objective evidence of tumor regression. After developing a clinical suspicion that tumor growth accelerated with SMS 201-995, we observed 10 patients closely for 2 months before beginning SMS 201-995 treatment and for the first 2 months on the therapy. In these 10 patients, the serum prostatic acid phosphatase level rose at an accelerated rate after 1 to 2 months of treatment. Among the 20 patients treated and evaluable for response, new osseous metastases developed in 12 and new visceral metastases in 4; 1 developed disseminated intravascular coagulation and 2 developed neurologic complications (mean time to objective progression, 5.6 weeks). Six patients received salvage chemotherapy after disease progressed on SMS 201-995 therapy, 5 of whom have achieved objective tumor regressions. We believe SMS 201995 stimulates prostatic tumor growth and may sensitize tumor cells to subsequent chemotherapy.

A 63-year-old woman was in hospital for persistent backache. Four months prior to admission she had been pointed out as having hypertension for the first time. On admission, she had anemia (hemoglobin 7.0 g/dl) with reticulocytosis, and a blood smear showed fragmented erythrocytes. A bone marrow aspirate disclosed erythroid hyperplasia and invasion of cancer cells. The chest roentgenogram showed a coin-lesion of the right lung and left pleural effusion. A diagnosis of microangiopathic hemolytic anemia (MAHA) associated with carcinomatosis was made, but the primary site of the cancer was unknown. Respiratory failure developed and the patient died a month later. Surprisingly, the autopsy revealed a malignant pheochromocytoma arising from the right adrenal gland with massive metastases to the lungs, liver, lymph nodes and systemic bones, and also disseminated intravascular coagulation (DIC). The DIC would probably account for the MAHA in this case. To our knowledge, this is the first reported case of malignant pheochromocytoma accompanied by MAHA.

We report a 24-year-old man who presented unilateral multiple cranial nerve involvements followed by progressive paraplegia. The patient expired after developing DIC and pneumonia. Post-mortem examination revealed Ewing's sarcoma originated in the pubic bone with extensive metastases including the clivus which was responsible for his cranial nerve lesions. The patient was well until 24 years of age when he noted an onset of pain and a mass in the pubic region. The histology of the biopsy specimen of the tumor suggested Ewing's sarcoma. He was treated with chemotherapy and local radiation. A year after, he noted an onset of nuchal pain, difficulty in tongue movement, dysarthria, deafness in the left ear, and diplopia. On admission to our hospital in July 1990, neurological examination revealed an alert and intelligent Japanese male in no acute distress. The olfactory to the trigeminal nerves appeared intact. He showed complete abducens nerve palsy, facial weakness, mild deafness, and weakness of the soft palate, the sternocleidomastoid muscle and the tongue, all on the left side. The remainder of the neurological examination was unremarkable except for dysesthesia along the left C8 and Th1 dermatoms. Radiological examination revealed a 10 x 10 cm sclerotic mass in the public bone and a high signal mass lesion between the clivus and the pons in the T2-weighted MRI. His clinical course was complicated by acute paraplegia with anesthesia below the Th4 dermatom, DIC, and respiratory distress due to plural effusion. Post-mortem examination revealed a necrotic and hemorrhagic tumor in the pubic bone. The histology was consistent with Ewing's sarcoma.(ABSTRACT TRUNCATED AT 250 WORDS)

A 51-year-old man presented with headache, vomiting and exophthalmus. Neurological examination revealed anosmia, papilledema, decrease in visual acuity, and disability in ocular movement. MRI showed a huge mass which occupied the whole nasal cavity and compressed the frontal lobe upwards and the eyes laterally. CT revealed an extensive bony destruction of the frontal base and bilateral orbits. The mass was biopsied transnasally, and was histologically diagnosed as olfactory neuroblastoma. It was highly radiosensitive and disappeared with a local irradiation of 40 Gy. Three months later the patient complained of a pain radiating from the neck to the right arm. MRI demonstrated a metastasis at the vertebral body of C5. Local irradiation of 30 Gy was performed. The metastatic lesion was removed, and a bone graft taken from the iliac bone was transplanted via an anterior cervical approach. Three weeks later, however, a hard mass appeared in the right of his neck and was surgically removed. By histological examination, it was also identified as a metastatic neuroblastoma to the cervical lymph node. A week after the removal of the cervical metastatic lesion, the metastasis extended rapidly to the left cervical and the bilateral hilar lymph nodes of the lungs. Chemotherapy was performed with a total doses of 800mg of cyclophosphamide, 1.5mg of vincristine, 40mg of pirarubicin, and 80mg of cisplatin. The lesions disappeared within 7 days. However, the patient died from disseminated intravascular coagulation 10 months after the onset. Olfactory neuroblastoma is usually an intranasal neoplasm, but it rarely extends intracranially and intraorbitally as is shown in our case. Basically, olfactory neuroblastoma is a relatively slow-growing tumor though it has a tendency to develop local recurrences over long periods even after aggressive primary treatment, and accompanied with distant metastases. However, our patient showed a very short survival time. Invasive extension and multiple metastases occurred during a short period, followed by disseminated intravascular coagulation. Combined chemotherapy at the initial treatment may be recommended in such an extensive case.
