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.

Eighty-seven adult patients who had achieved bone marrow remission of leukemia developed one or more episodes of meningeal leukemia. Multiple patient characteristics were examined for their effect on probability of achieving complete remission from meningeal disease and for their effect on duration of meningeal remission. Presence of obtundation (P less than 0.01) or other symptoms of meningeal disease (P = 0.02) were associated with a low remission induction rate. Other factors which tended (P = 0.06-0.20) to be associated with low remission induction rates included high cerebrospinal fluid (CSF) opening pressure, absence of splenomegaly at initial diagnosis, high peripheral blood leukocyte count (WBC) at the episode of marrow disease most recently preceding the meningeal disease, and use of only one as opposed to two or more intrathecal drugs as treatment. Factors associated with long duration of meningeal remissions included diagnosis (AML greater than acute undifferentiated leukemia greater than ALL, P = 0.05), absence of symptoms (P = 0.04), low CSF WBC (P = 0.01), rapid attainment of meningeal remission (P = 0.01), rapid attainment of initial bone marrow remission (P = 0.02), and long duration of initial bone marrow remission (P less than 0.01). Absence of cranial or peripheral neuropathies, low CSF protein and opening pressure, and short time interval between diagnosis of marrow and meningeal disease also tended (P = 0.06-0.20) to be associated with long meningeal remissions. Patients treated according to an intensive protocol utilizing cranial irradiation and triple drug treatment via an Ommaya reservoir had substantially longer meningeal remissions than did patients treated with less intensive therapy (P = 0.01). Relapse-free survival curves suggest that some patients are cured of their meningeal disease.

Platelet transfusions are an important supportive measure during treatment for acute nonlymphocytic leukemia (ANLL). The presence of splenomegaly may produce decreased posttransfusion platelet increments leading some to recommend an increased dose of platelets per transfusion in this situation. Forty-nine newly diagnosed patients with ANLL were evaluated during 1980 and 1981, and 24% had palpable splenomegaly. Although treated with usual doses of platelets per transfusion, there was no detectable statistical increase in transfusion requirement or incidence of hemorrhage in patients with splenomegaly. Experimental evidence indicates that the splenic platelet pool enlarges with splenomegaly, but the life span of circulating platelets is not significantly changed. Furthermore, the splenic platelet pool is in dynamic equilibrium with the circulating platelet pool thus allowing these platelets to participate in hemostasis. Although posttransfusion increment in platelet count may be less, it appears that platelet transfusion therapy need not be altered solely because of splenomegaly.

Review of 5406 children with acute lymphoblastic (ALL) or nonlymphoblastic leukemia (ANLL) registered with Childrens Cancer Study Group (CCSG) since 1972 identified 115 patients (2.1%) with Down syndrome. The proportion of patients with Down syndrome was the same for ALL (2.1%) and ANLL (2.1%). Patients with ALL with and without Down syndrome did not differ significantly with respect to age at diagnosis, sex, race, morphology (FAB classification), cell surface markers, initial white blood cell count, pretreatment hemoglobin value, hepatomegaly, lymphadenopathy, presence of mediastinal mass, CNS disease at diagnosis, or prognostic group as defined by age and initial white blood cell count. Patients with ALL-Down syndrome less frequently had splenomegaly, had lower pretreatment platelet counts, and more often had normal or elevated IgG or IgA levels. In addition, they had a significantly lower rate of remission (81% versus 94%), a higher mortality during induction therapy (14% versus 3%), and a poorer overall survival with 5-year life table rates of 50% versus 65% (P less than 0.001). If an initial remission was achieved, there were no significant differences with respect to remission duration, survival, or disease-free survival. Patients with ANLL-Down syndrome were younger at diagnosis than those without Down syndrome. There was no significant difference in the remission rates between these patients. Analysis of findings in patients with ANLL provided results similar to those obtained for patients with ALL with regard to clinical outcome after achievement of an initial remission.

40 children (23 males, 17 females) have been diagnosed have ANLL during the period from february 1970 to september 1981. According to FAB classification, 24 cases were M1,-M2, 9 M3, 3 M4, 3 M5 and 1 M6. At diagnosis, 20 patients (50%) had leukocytes less than 10.000/mmc, 6 (15%) had leukocytes greater than 50.000mmc. Hb levels was 7 g% in 16 patients (40%); 10 children had hepatosplenomegaly (25%), 7 splenomegaly (18%) and 5 lymphoadenomegaly (13%). 4 patients had cutaneous or mucous infiltrates. None had meningeal involvement at diagnosis. According to the year of diagnosis, 3 groups can be identified. In the group I (1970-73), 11 patients have been treated with not codified combination chemotherapy as ARA-C, 6-TG, DNR, CTX, Metil-GAG. In the group II (1974-76) and in the group III (1977-81), the patients (respectively 12 and 17) have been treated according to the following protocols: LAM-5 (3), TRAP (5), COAP (1), LAM 80 (2), AIL 7402 (8), AIL 7604, AIL 7801 (6). Immunotherapy has been performed in 7 cases. CNS prophylaxis (MTX i.t. +/-ARA-C +/- RT) was given in 5 patients of group II and in 6 of group III. I patients of group I (45%), 6 of group II (50%) and 13 of group III (76%) achieved CR. Median duration of remission was 5 months in the group I and in 17 in group II and III.(ABSTRACT TRUNCATED AT 250 WORDS)

Fifty-two patients with different types of leukemia [27 chronic lymphocytic leukemia (CLL), 10 acute myeloblastic leukemia (AML), eight acute lymphoblastic leukemia (ALL), four chronic myelogenous leukemia (CML), and three hairy cell leukemia (HCL)] had abdominal and pelvic CT. The radiographic features are reviewed to evaluate the role of CT in diagnosis and management of these patients. The highest incidence of lymphadenopathy was observed in CLL followed by HCL and ALL. Other findings included splenomegaly, hepatomegaly, ascites, pleural effusion, microabscesses in liver and kidney, and visceral involvement, i.e. intestine, bladder, and bone.

Utilizing multivariate logistic regression statistical analysis, the authors evaluated prognostic features associated with achievement of complete remission (CR) and remission and survival duration in acute myelogenous leukemia (AML). These clinical variables were analyzed in 77 consecutive adult patients who underwent 108 courses of remission induction therapy with daunomycin, cytosine arabinoside, and 6-thioguanine (DAT) chemotherapy for newly diagnosed and first relapse of AML. Eight patients had developed leukemia in the setting of other malignant or immunologic diseases (therapy-linked AML) and 69 patients had not (primary AML). Sixty-three percent of patients with primary AML achieved CR with median remission and survival durations of 11 and 24 months, respectively. Significant unfavorable predictive features for achievement of CR were splenomegaly, and elevated leukocyte count or serum alkaline phosphatase levels. Patients who had leukocyte counts of less than or equal to 10,000/mm3 at diagnosis or less than or equal to 40,000/mm3 at the start of therapy, and those who received greater than 120 mg/m2 of daunomycin had significantly longer remissions and survival than those who did not. Fifty-seven percent of patients in first relapse also achieved CR; however, relative to first remissions, second remission durations were significantly shorter (median, 4.6 months). Sixty-two percent of patients with therapy-linked AML achieved CR, but remission durations (median, 2.8 months) were significantly shorter than first remissions of primary AML patients. These data identify clinical features associated with increased risk of failure to achieve CR and potential for short remission duration and survival. Alternative forms of therapy should be considered for such high-risk patients.

75 cases of acute myeloid leukaemia were retrospectively classified according to the French-American-British (FAB) classification. It was found that: (1) the proposed classification was easily applicable and reproducible; (2) M2 subtype was the most frequent (48%); (3) splenomegaly was absent in M1 subtype, and (4) in M2 subtype, a considerable number of cases presented with normal neutrophil and platelet counts.

Fifteen of 73 newly diagnosed patients with acute myeloid leukemia (AML), admitted to Mount Sinai Hospital between July 1977 and October 1979, presented with leukocyte counts greater than 100,000/microliter. Eleven of these 15 patients with hyperleukocytosis had myelomonocytic (AMML-M4) or monocytic (AMOL-M5) leukemia compared to 15 of 58 patients with lower white cell counts (p < 0.001). Identification of type of leukemia, using the FAB classification, was based on morphology and special stains, including myeloperoxidase, Sudan black B, periodic acid-Schiff and nonspecific esterase with and without inhibition by fluoride. The proportion of patients with splenomegaly is higher in those with hyperleukocytosis (73 percent) than in those with lower white blood cell counts (p < 0.001) regardless of cell type. Leukemic infiltration of the skin, gums and central nervous system was seen exclusively in patients with AMML and AMOL. The serum lysozyme levels were significantly higher for all patients with AMML and AMOL regardless of the white blood cell count. The mean serum lysozyme for M-4, M-5 patients was 59.7 microgram/ml compared to 18.9 microgram/ml in patients with other cell types (p < 0.0001). Patients with a white blood cell count less than or equal to 100,000/microliter had a complete remission rate of 69 percent compared to 47 percent for patients with higher white blood cell counts.

8;21 translocation was found in 10 AML patients. These patients exhibited a distinct clinical and haematological picture, characterized by M2 bone marrow, with rather good maturation, a high count of mature granulocytes, splenomegaly, and the absence of DIC. Complete remission as easily obtained. It was reported that the median survival is better than for other AML patients with abnormal karyotypes, but this could not be substantiated in our small series. The loss of a sex chromosome was found to be frequent and of poor prognostic significance.
