On a prospective fashion during approximately two years, 22 pediatric patients with acute non lymphocytic leukemia were evaluated. Of this population the majority had acute mielocytic leukemia, followed by acute myelomonocytic leukemia. Absolutely all patients at the time of diagnosis and subsequently every 4 to 6 weeks had a bone marrow aspiration test. When the patients were first seen, 54% of them presented fever; lymph node enlargement was not a common finding. Only few of this patients presented splenomegaly and/or hepatomegaly. In regards to complete blood counts the most outstanding of its was the presence of leukocyte count above 20000/mm.3 in 8 of this patients. From the 22 patients studied only 21 are evaluable. All 21 patients were treated with a 4 drug combination (modified COAP). Sixteen patients (76%) achieved bone marrow remission, of which only 15 patients (71%) achieved complete remission. The median duration remission was of 9.2 months with a range of 2 to 26 months. At the present time only 7 patients (33%) are alive and on remission. Two more patients are alive but in full relapse. The mortality rate of this study is of 59%. The review of recent chemotherapy reports is presented and the need for further trials is emphasized especially in view of recent papers published in which it appears that better results are being obtained at last in children's acute non lymphocitic leukemia.

Eleven patients with acute non-lymphocytic leukemia developed hepatosplenic candidiasis following the termination of chemotherapy. Five who did not receive amphoteicin B (AMPH) died of liver failure, whereas the other six who received AMPH and/or miconazole or fluconazole were cured. The features of hepatosplenic candidiasis included prolonged high fever not responsive to antibiotics and hepatomegaly with right-sided hypochondrial pain developing after severe neutropenia. Even if the neutropenia recovered, these symptoms did not subside. In addition, elevation of the serum alkaline phosphatase and total bilirubin levels were observed at onset. CT scan revealed multiple low-density areas of varying size that showed no contrast enhancement. Ultrasonography also demonstrated hypoechoic or hyperechoic lesions, and a so-called "target sign appearance" in the liver and spleen. The clinical diagnosis for hepatosplenic candidiasis is not so difficult because of the uniform symptoms, signs and laboratory abnormalities. The importance of the early administration of antifungal agents to obtain a cure is discussed in this article.

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.

Analysis of remission induction rates for 1,117 children 18 months to 10 years of age (group 1) and 90 infants less than 18 months of age (group 2) with acute lymphoid leukemia (ALL) and of duration of continuous complete remission (CCR) for 454 in group 1 and 33 in group 2 revealed that infants fared significantly worse in both measures of outcome (P = .03 and P less than .0001). To examine potential reasons for the poor prognosis of affected infants, clinical and biologic features of their ALL were compared. Infants had higher WBC counts (P less than .001), a higher incidence of massive splenomegaly (P less than .001), massive hepatomegaly (P less than .001), more central nervous system (CNS) disease at diagnosis (P less than .01), and lower platelet counts (P less than .001). Also, their blasts were less often PAS+ (P = .02). The incidence of non(T, B, pre-B), T and pre-B immunophenotypes of ALL did not differ significantly between the two groups. However, in patients with non(T, B, pre-B) ALL, the majority (51%) of infants had common ALL antigen (CALLA)-negative blasts, as compared with only 7% in group 1 (P less than .001). Furthermore, infants with non(T, B, pre-B) cell ALL who were less than 12 months of age were almost always CALLA- (18 of 21). The blasts of children from both groups usually expressed Ia-like antigens. These data illustrate that infants with ALL have extensive and bulky disease more often than do older children and are more often affected with a prognostically unfavorable phenotype of acute leukemia (AL) which expresses Ia-like antigens but is more often PAS- and CALLA-. We believe that these clinical and biological differences predict and explain in part the observed poor response to treatment of infants with ALL.

Nineteen cases of canine acute leukemia were diagnosed during a 4-year period. Two main categories were identified on the basis of cytologic, hematologic, and clinical features: acute lymphoid leukemia and acute myelogenous leukemia. Clinical features included history of weight loss, anorexia, shifting limb lameness, and incoordination. Physical findings were characterized by hepatomegaly, splenomegaly, mild generalized lymphadenopathy, and pallor. Ocular lesions were found in 29% of dogs with acute myelogenous leukemia. Hematologic abnormalities included anemia, thrombocytopenia, pancytopenia, leukemia, and leukoerythroblastic reactions. Results of therapy were discouraging.

Erythroblastopenia occurred in the course of chronic B cell lymphocytic leukemia. The failure of chlorambucil therapy prompted the decision of thymic irradiation. This was effective on the lymphoid proliferation but did not modify the erythroblastopenia. Progressive hepatomegaly led to the diagnosis of hepatoma.

The serum levels of soluble intercellular adhesion molecule 1 (ICAM-1) were significantly elevated (P < .001) in patients with chronic B-lymphocytic leukemia (B-CLL, n = 113) compared with healthy controls (n = 31). sICAM-1 levels in B-CLL were positively correlated to the tumor mass as reflected by the modified Rai and the Binet staging systems, lymphocyte counts, and isolated spleno/hepatomegaly. During disease progression or regression on cytoreductive therapy, the circulating sICAM-1 levels changed accordingly. sICAM-1 was also correlated to a kinetic parameter such as the lymphocyte doubling time. Furthermore, the serum sICAM-1 levels were inversely correlated to hemoglobin levels in patients with early clinical stage, and this may turn out to be of prognostic value. sICAM-1 was compared with other serum markers said to reflect disease activity in B-CLL, ie, soluble CD23, thymidine kinase, lactate dehydrogenase (LDH), and beta 2-microglobulin. sICAM-1 was equally well or better correlated to clinical stage and lymphocyte doubling time. In univariate regression analysis, all serum markers but LDH correlated with survival, and in multivariate analysis, sICAM-1 was the only marker approaching significance for additional prognostic information when included after clinical stage and lymphocyte doubling time. Based on the present observations, it appears that prospective studies repeatedly monitoring serum sICAM-1 in B-CLL are justified.

The incidence of trisomy 12 and p53 deletion was studied in a group of chronic B-lymphocytic leukemia (B-CLL) patients, using fluorescence in situ hybridization (FISH). Trisomy 12 was detected in eight of 50 patients (16%) and p53 deletion in six of 38 cases analyzed (15.8%). A statistically significant difference was observed between the incidence of trisomy 12 in patients with typical and atypical morphology (3.03% versus 41.18%). No correlation was found between this alteration and the rest of the clinical and biological parameters studied (adenopathies, hepatomegaly, splenomegaly, lymphocyte count, staging, CD11c expression, and resistance to chemotherapy). The p53 deletion was correlated with the presence of hepatomegaly and splenomegaly, advanced stage of disease, and resistance to conventional chemotherapy. The application of FISH to whole blood cell nuclei, without prior manipulation or culture, showed a higher percentage of cells with trisomy 12 than when the method was used following culture. We conclude that 1) FISH is a simple and sensitive technique for the detection of numerical and structural chromosome abnormalities; 2) Its application to uncultured samples obviates the alteration of results originated by the probable growth advantage of the normal or neoplastic cell population in vitro; 3) Trisomy 12 appears to define a B-CLL subgroup of atypical morphology; and 4) The p53 deletion is correlated with advanced stage of disease and resistance to treatment.
