Hemostatic changes were evaluated in ten patients with acute lymphoblastic leukemia and lymphoma who received chemotherapy with L-asparaginase, vincristine, and prednisolone for 1 week. Following treatment, prothrombin time and activated partial thromboplastin time were significantly prolonged, while a marked decrease in fibrinogen levels was observed. The values for cross-linked fibrin degradation products, however, remained within normal limits during treatment, which excluded the possibility of disseminated intravascular coagulation. The concentrations of coagulation inhibitors (antithrombin III, protein C, and protein S), plasminogen, and alpha 2 antiplasmin also significantly decreased; however, levels of both tissue-type plasminogen activator and plasminogen activator inhibitor, which are synthesized in endothelial cells, increased during the treatment. Although a decrease was observed in concentrations of many coagulation factors, including subunits A and B of factor XIII, the activity and antigenicity of factor VII significantly increased following the treatment. From this study, we concluded that these hemostatic abnormalities caused by the administration of L-asparaginase produced a labile condition that easily inclines to bleeding or thrombosis.

The central nervous system (CNS) has been examined at autopsy in 89 patients who died of the acquired immune deficiency syndrome (AIDS), including 14 patients who died primarily of neurologic complications of the disease. A total of 66 brains (74%) showed significant pathologic abnormalities, with opportunistic infections including cytomegalovirus (14) and cryptococcal (11) infections, progressive multifocal leukoencephalopathy (6), toxoplasmosis (6), and histoplasma microabscesses (1). Incidental Mycobacterium avium-intracellulare infection was found in 4 cases. Simultaneous CNS infection by more than one microorganism was encountered in 5 patients. Subacute (microglial nodule) encephalitis-related to cytomegalovirus infection or possibly brain infection by the causative agent of AIDS was present in 56 cases. Primary CNS lymphoma was noted in 3 patients. Secondary CNS deposits of lymphoma were found in 1 patient, and another patient had lymphomatoid granulomatosis. Vascular complications were not infrequently seen, and included infarcts secondary to vessel occlusion and disseminated intravascular coagulation in 4 patients and intracranial hemorrhage of variable severity in 13. White matter changes included vacuolar myelopathy (3 cases), central pontine myelinolysis (1 case), and foci of calcified, necrotizing leukoencephalopathy in pontocerebellar fibers of the basis pontis (2 cases). These findings highlight the variety of CNS complications in AIDS, some of which are not associated with clinical manifestations. Nevertheless, characterization of all lesions may be important in understanding the neurologic sequelae of AIDS.

A 45-year-old man was admitted to hospital on November 26, 1985 with the chief complaint of left hypochondrial pain. Excretory and retrograde pyelography revealed left hydronephrosis due to extrinsic obstruction of ureter. Computerized tomography and angiography revealed that a tumor of the small intestine was the cause of ureteral obstruction. In addition to the presence of a tumor, a fistula in the small intestine was disclosed on the upper gastrointestinal series. During the operation, a large mass which involved several organs was identified without mobility. The sophisticated operation was composed of wide resection of small intestine including the tumor, left hemicolectomy, left nephroureterectomy, splenectomy, partial pancreatectomy, duodeno-ileostomy and transverse sigmoidostomy was done on December 19, 1985. Pathological diagnosis was malignant lymphoma, diffuse small cell type infiltrating ureter, kidney and perirenal connective tissue. Because of poor postoperative course systemic chemotherapy was not performed and he died of disseminated intravascular coagulation on April 2, 1986.

A 55-year-old man was admitted to our hospital with fever, ascites, generalized lymphadenopathy and hepatosplenomegaly. A cervical lymph node was biopsied and diagnosed as a diffuse mixed cell type B-cell malignant lymphoma with positive cytoplasmic IgM in plasmacytoid lymphocytes and immunoblasts. Serum protein electrophoresis disclosed a monoclonal peak and immuno-electrophoresis identified the abnormal protein as IgM kappa(k). Serum immunoquantitation revealed an IgM level of 1470 mg/dl. Bence-Jones protein of the k type was positive in the urine. Cryoglobulin with the characteristics of IgM was present in the serum. In peripheral blood, hemoglobin was 12.4 g/dl, WBC 26,500/microliters with increased abnormal cells and the platelet count 2.2 x 10(4)/microliters. Low fibrinogen and high FDP levels indicated the existence of disseminated intravascular coagulation (DIC). Gabexate mesilate (FOY) was administered at a dose of 1,000 mg/day for the DIC with very good response. After one course of combination chemotherapy (vincristine, cyclophosphamide, prednisolone, adriamycin), he achieved complete remission. However, three months later, he showed icterus and anorexia again with high levels of serum GOT and GPT and positive HBs antigen. On the 117th hospital day, he became abruptly developed right hemiplegia and coma. Cranial CT demonstrated massive thalamic bleeding in the left hemisphere with ventricular rupture, and he died on the same day.

To assess the role of the general surgeon in the care of patients with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex (ARC) the hospital records of all patients with AIDS or ARC who underwent a major operation at the General Surgical Service of Crawford W. Long Memorial Hospital were reviewed. Of 79 patients with AIDS or ARC diagnosed since 1982, 14 required major abdominal surgery. Operations performed were for gastrointestinal (GI) complications of opportunistic infections and neoplasms (four), diagnosis of major retroperitoneal lymphadenopathy (four), and treatment of AIDS-related immune thrombocytopenia (six). GI complications consisted of two cases of cytomegalovirus perforation of ileum and colon, one case of bleeding ileocolonic lymphoma, and one case of cryptosporidium cholecystitis. Laparotomy for diagnosis of retroperitoneal lymphadenopathy was performed in four patients and provided diagnostic material in three of them. Six patients underwent splenectomy for AIDS-related immune thrombocytopenia. Four of these patients had previously been treated with prednisone without impressive results. All patients had marked improvement of their platelet counts and clinical bleeding after splenectomy. Postoperative complications were common and consisted of wound infection, disseminated intravascular coagulation, GI bleeding, pneumocystis pneumonia, small-bowel obstruction, and cytomegalovirus pneumonia. One patient died after laparotomy for perforated ulcers of the ileum and colon.

Thirty-seven dogs with malignant lymphoma were treated with either polyethylene glycol conjugated (PEG) asparaginase alone (10-30 IU/kg intraperitoneally [IP] weekly--20 dogs) or PEG-asparaginase combined with one cycle of chemotherapy (vincristine, cyclophosphamide, methotrexate, and prednisone), followed by maintenance PEG-asparaginase (30 IU/kg, IP weekly--17 dogs). In the 20 dogs (eight were chemotherapy resistant) treated with PEG-asparaginase alone, seven had a complete response (CR), seven had a partial response (PR), five had no response (NR), and one was not evaluable (NE). The duration of response (CR + PR) ranged from 14 to 102 days (median, 48 days). In the eight chemotherapy-resistant dogs (seven were previously resistant to L-asparaginase) four had responses (one CR and three PR). In the 17 dogs treated with combined PEG-asparaginase and chemotherapy, 13 had a CR, two had a PR, and two had NR. None of the dogs had had prior chemotherapy, and the duration of response (CR + PR) ranged from 7 to 840+ days, with a median of 126+ days. Four dogs are still on maintenance PEG-asparaginase at 16+, 21+, 26+, and 28+ months. Toxicity consisted of death due to massive tumor breakdown (two dogs), disseminated intravascular coagulation (DIC--one dog), hypersensitivity reaction (one dog), vomiting (three dogs) and soft stools (three dogs). Four normal dogs were given very high doses of PEG-asparaginase (200 IU/kg and 1200 IU/kg) once weekly for two treatments without any significant toxicity. These results indicate that PEG-asparaginase has antitumor activity in dog with spontaneously occurring malignant lymphoma.

Sixteen dogs with lymphoma underwent splenectomy to relieve signs of massive splenomegaly including splenic rupture. The most common preoperative hematologic abnormalities, anemia and thrombocytopenia, were reversed in all dogs surviving the initial postoperative period. Within 6 weeks after surgery, 5 dogs died because of disseminated intravascular coagulation and sepsis. The remaining 11 dogs underwent chemotherapy. These 11 dogs had a complete response rate of 66% at one month after surgery; the mean and median survival times were 9.3 and 5 months, respectively. In 7 dogs evaluated until death, the mean and median survival times were 13.4 months and 14 months, respectively.

We studied the clinical, morphological, and immunologic characteristics of 11 patients with 11q translocation-associated acute leukemia. There were three patients with t(9;11)(p22;q23), one with a variant of the t(9;11), three with t(11;19)(q23;p13), two with t(1;11)(p32;q23), one with t(10;11)(p15;q22or23), and one with t(11;17) (q23;q25). The breakpoints in chromosome 11 clustered in band q23. The morphological feature was FAB-M5 in two patients, FAB-M2 in one, FAB-L1 in six, and lymphoblastic lymphoma in one. The remaining patient underwent morphological changes from FAB-L1 seen at the time of diagnosis to M5b at relapse. Immunologic marker studies in ten patients revealed that one had T cell type; another pre-B cell type; three CALLA- Ia- non-T, non-B type; two CAL-LA- Ia+ non-T, non-B type; two monocytic type (positive Fc-receptor); and the remaining one underwent phenotypic changes from CALLA+ Ia+ non-T, non-B type to monocytic type. The patients were usually young; five were under 1 year and two were 9 and 13 years. Hyperleukocytosis was observed in eight of the ten patients with acute leukemia, and two of the eight died of intracranial hemorrhage within two days of admission, associated with disseminated intravascular coagulation. These findings indicate that leukemia with the 11q23 translocation share certain characteristics in common, irrespective of the recipient chromosome, even though the latter may have some influence on the morphological and immunologic phenotype. Our data provide a hypothesis that multipotent stem cells are involved in the genesis of the 11q translocation-associated leukemia.

A case of malignant lymphoma in the skull after head injury associated with whole bone metastasis is reported. The patient was a 66-year-old man who was admitted to Almeida Memorial Hospital because of headache and general fatigue 2 months after head injury. After admission tumors appear in the frontal and occipital region and grew rapidly. Plain craniogram revealed large map-like bone destructions and multiple punched out lesions. Bone scintigram with 99mTc-MDP revealed multiple accumulations of RI in the skull, vertebrae, ribs and pelvis. CT scan revealed destructive, markedly enhancing bone tumor which was compressing the brain as an extradural mass in the left frontal and occipital regions. Pathological examination of the tumor revealed malignant lymphoma of non-Hodgkin type and diffuse pleomorphic type. Though combination chemotherapy with ACNU, FT 207, PSK, CHOP (Cyclophosphamide, Adriamycin, Vincristine and Predonisone) and Acracinomycin A was performed after operation, and brought forth regression of tumor size and improvement of clinical symptoms transiently, he died 6 months after the onset because of recurrence in many bones with pathological fracture and complications such as pneumonia, DIC and acute renal failure. At autopsy the tumors were found to be localized only in the bones, but in none of lymphnode or visceral organs. Malignant lymphoma appearing initially as a skull tumor is rare, and its diagnosis and treatment were discussed.

A 28-year-old man developed AML 18 months after a diagnosis of non-Hodgkin's lymphoma, diffuse small cell type, clinical stage IIA. Induction therapy for the lymphoma consisted 60Co 4000 rads bilaterally to the cervical areas and 2000 rads to the right cervical area. Complete remission was attained. Nineteen courses of combination chemotherapy with Vincristine (VCR), 6-meraptopurine (6 MP), cyclophosphamide (CY) and predonisolone (pred) was added (Total dose: VCR; 26.5 mg, 6 MP; 3320 mg, CY; 3350 mg, pred; 4310 mg). Seven days after the final chemotherapeutic treatment he developed AML with DIC. Leukemic cells were peroxidase and specific esterase (naphthol AS-D chloroacetate) positive. Induction therapy for the AML consisting of DCMP (Daunomycin, Cytosine arabinosid, 6 MP and pred) and VCR (vindesine, CY and pred) was unsuccessful. The patient died of cranial hemorrhage 3 month after the diagnosis of acute leukemia. Autopsy revealed no recurrence of non-Hodgkin's lymphoma in the lymph nodes, bone marrow, spleen and liver. Seven other cases reported in the Japanese literature are reviewed.
