Tender hepatomegaly and ascites occurred in a young woman receiving cytosine arabinoside and daunorubicin for acute myelogenous leukemia. Whereas veno-occlusive disease was suspected clinically, liver biopsy showed nodular regenerative hyperplasia with no evidence of hepatic vein abnormalities. It is postulated that nodular regenerative hyperplasia can be initiated by hepatotoxicity of chemotherapy agents used to treat leukemia and/or that these agents exacerbate clinical manifestations of this histological abnormality. Nodular regenerative hyperplasia should be added to the list of liver problems occurring in patients with leukemia.

Forty-eight Japanese infants with acute lymphoid leukemia (ALL) (n = 24) and acute nonlymphoid leukemia (ANLL) (n = 24) were analyzed on the basis of clinical and laboratory data. Morphologically, 20 of the 24 infants with ALL were of the FAB L1 type, and 20 of the 24 infants with ANLL were of the M4 or M5 type. Markedly enlarged liver and spleen, and hyperleukocytosis (more than 50,000/microliters) were seen in 9, 12, and 14 infants with ALL and 10, 11, and 10 infants with ANLL, respectively. Initial CNS leukemia was evident in 2 infants. Chromosome studies of the leukemic cells showed abnormal karyotypes in 9 of the 21 infants with ALL and 19 of the 22 infants with ANLL, consisting mainly of translocation 11, 12, and inversion 16. By surface marker analysis, only 7 of the 22 infants with ALL (32%) were diagnosed as having common ALL (HLA-DR+, CD19+, CD10+). Of the 15 infants with ANLL, 12 and 5 infants also showed reactivity to HLA-DR and CD19, respectively. All of the 5 ANLL infants with lymphoid markers showed different leukemic cell features at the time of relapse. Twelve of the 19 infants with ALL (63%) who achieved a complete remission relapsed within the first 2 years; 8 of the 21 with ANLL (38%) relapsed within the first year. Analysis of event-free survival shows that the ALL infants with hyperleukocytosis have a poorer prognosis than those without hyperleukocytosis (p less than 0.05). Infant leukemia originates in a multipotent cell with lymphoid and myeloid features, and intensive multiagent chemotherapy is necessary for the treatment of infants with acute leukemia.

The immunophenotype of leukemicblasts from 111 patients with T-ALL or T-NHL were further examined by using a panel of standardized McAbs of CD nomenclature to human leukocyte differentiation antigens. Four major subsets of T-ALL were defined: pre T-ALL, immature T-ALL (I), common T-ALL (II) and mature T-ALL (III), with the percentages 20.7%, 20.7%, 20.7% and 37.0% respectively. In addition there was a case with M-T acute hybrid leukemia. Some of the clinical features of the patients with T-ALL and T-NHL were compared. It was found that male predominance, older age, higher leukocyte count, lower platelet level, relative higher hemoglobin level and increased incidence of extramedullary involvement, including hepatomegaly, splenomegaly and lymphadenopathy were alike for all subsets of T-ALL cases. However, the average white cell level and incidence of lymphadenopathy in the pre T-ALL subset significantly differed from those in other subsets. The correlation of immunophenotype with morphologic characterization was also discussed in this paper.

Chronic granulocytic leukaemia (CGL) is the commonest leukaemia among adults in India. Case records of 183 CGL patients diagnosed between 1975 and 1985 were reviewed. The median age at diagnosis was 40.5 years. Most patients presented with weakness, fullness in the left upper abdomen and fever. Splenomegaly and hepatomegaly were present in 90% and 48% respectively. Patients were treated with oral, intermittent busulphan with monitoring of total leucocyte count. Overall, 87 patients expired, including 63 (72%) due to blast crisis. The median survival was 33 months from diagnosis and 44 months from the onset of symptoms.

Prostaglandin E1 (PGE1) was used to prevent veno-occlusive disease (VOD) of the liver after allogeneic bone marrow transplantation (BMT) for leukaemia. It was given in continuous i.v. infusion from day--8 to day 30 after BMT at a dose of 0.3 micrograms/kg/h. The patients were studied according to the risk factors for VOD: diagnosis, intensification of the conditioning and previous liver abnormalities. The diagnosis of VOD was made on at least two of the following factors: weight gain, hepatomegaly, jaundice, ascitis, pain of the right upper quadrant, increased platelet consumption. 109 patients were studied, 50 were treated by PGE1 and 59 did not receive it. The actuarial incidence of VOD was 12.2% in the PGE1 group and 25.5% in the non PGE1 group (P = 0.05). In acute leukaemia, the incidence was 39.1% in the non-treated group and 12.8% in the PGE1 treated group (P = 0.02). Patients with previous hepatitis had an incidence of 62.5% in the non treated group and 15.5% in the treated group (P = 0.05). A positive cytomegalovirus (CMV) serology seemed to increase the risk of VOD: the incidence of VOD was 31.4% in non-treated patients and 22% in PGE1 treated patients. The multivariate analysis of the risk factors for VOD shows that unfavourable factors were: recipient positive CMV serology (P = 0.06), hepatic disease prior to transplant (P = 0.02) and the absence of PGE1 treatment (P = 0.02). This study suggests that prophylactic PGE1 treatment may decrease the incidence of VOD in patients treated for leukaemia by allogeneic bone marrow transplantation.

Bovine leukemia virus (BLV) was inoculated into one-day-old chickens. In a small part of inoculated chickens leukemia developed during observation period of one year. Out of 88 birds inoculated, only 4 developed histopathologically verified leukemia. The induced leukemia was characterized by enlarged liver and spleen. The organs were infiltrated with leukemic cells. The DNAs of body organs of inoculated chickens were analysed by Southern blot hybridization for the presence of BLV specific sequences. Out of 9 suspicious chickens tested in 6 birds the BLV was found to be integrated into host DNA either as a complete viral genome or as a part corresponding to its 3'-end. The leukemic cells were monoclonal as regard to the integration site of the BLV provirus. Neither the expression of BLV provirus in chicken leukemic cells nor the antibody response to BLV antigens in inoculated birds was detected. The rearrangements and amplification of erb-B and myb loci of protooncogenes in leukemic cells was detected. There were no changes in loci of following protooncogenes: myc, sis, fes, fps, erb A, src and yes. All obtained data taken together suggest that the BLV induced leukemia in chickens is caused by insertional mutagenesis.

Thirty-four new cases of acute promyelocytic leukaemia (M3) were diagnosed at the authors' Centre between 1970 and 1988 (19 males and 15 females) with ages between 5 and 73 years (median age, 32 years). Three cases were of the hypogranular variant or M3-v (8.8%). The clinical picture included: haemorrhagic diathesis (85%), pallor/malaise (82%), fever/infection (41%), hepatomegaly (26%), splenomegaly (12%). Leucopenia of less than 5 x 10(9)/L was present in 23/34 cases, laboratory signs of DIC in 26/31, increased LDH, over 400 U/mL, in 6/31, and abnormal karyotype in 7/15. One of the patients rejected any treatment; two others died of brain haemorrhage before therapy was started, and seven died in the first two weeks of treatment. Of the 31 patients treated, complete remission (CR) was achieved in 21 cases (67.7%). Allogeneic BMT was carried out in two of them, with further relapse and death. Post-remission treatment was given to the remaining 19 patients, and there were 13 relapses. Six patients have been in CR, 5 of them after cessation of therapy, for the last 1.5-11.5 years. Age under 50 years and leucocyte count below 5 x 10(9)/L at diagnosis were favourable prognostic factors according to the univariate statistical analysis performed. The survival plateau of the actuarial curve was reached beyond 2.75 years by 15% of all the patients treated (33 cases), 23% of the patients who achieved CR (21 cases), 31% of the patients under 50 years of age and 5 x 10(9)/L leucocyte count at diagnosis (15 cases) and 36% of these last achieving CR (13 cases).

Infectious mononucleosis as a manifestation of primary Epstein-Barr virus infection occurs uncommonly in adults over age 40. While fever is almost universal, older patients with the disease often present without lymphadenopathy, pharyngitis, splenomegaly, lymphocytosis or atypical lymphocytes. Jaundice and hepatomegaly occur more commonly in older patients than in adolescents and create diagnostic confusion. Often, infectious mononucleosis in this age group is confused with lymphoma, leukemia or biliary obstruction, or is classified as "fever of unknown origin."

Acute nonlymphocytic leukemia was diagnosed in a 1-year-old Rhodesian Ridgeback. Clinical signs of disease included weight loss, anorexia, lethargy, lymphadenopathy, splenomegaly, and hepatomegaly. Doxorubicin was administered IV on day 4 at a dosage of 30 mg/m2 of body surface, followed 2 days later by oral administration of cyclophosphamide at a dosage of 100 mg/m2. The cyclophosphamide was given for 4 consecutive days (days 8, 9, 10, and 11), but the WBC count did not respond. The dog was administered 500 ml of blood; but on day 12, it died. Necropsy was not performed, but the presumptive cause of death was related to leukostasis.

Twenty-one children, between eight months and twelve years old, diagnosed as having acute nonlymphoblastic leukemia (ANLL), were treated with an intensive chemotherapy based on a modified VAPA protocol. Complete remission rate was 80%, and the 5 year-survival rate is 46%. One chloroma, one central nervous system, and four bone marrow relapses were observed; all except the first having an unfavourable outcome. Significant risk prognostic factors in this series proved to be hepatomegaly (greater than 5 cm) and delay in obtaining remission. No fatal complications were observed.
