We determined in 35 patients with severe thrombocytopenia (AML n = 10; ALL n = 4; CML = 1; idiopathic myelofibrosis n = 1, aplastic anemia n = 1; undergoing bone-marrow transplantation n = 17) factors influencing the corrected count increment (CCI) after platelet transfusions. Out of 195 transfusions 86 (44%) failed to increased platelet counts (CCI less than 5 X 10(9) platelets/l). A significant percentage of transfusion failures occurred in patients with splenomegaly and/or fever (54% vs. 29%; p less than 0.002). Antibodies directed against donor platelets were found only twice. No correlation between reactivities demonstrable by the lymphocytotoxic test (n = 144) or the radioimmune antiglobulin test (n = 67) and the CCI was obvious. HLA antigen identity was also not predictive. Thus, transfusion failures in patients with low alloimmunization will not be predicted by in vitro antibody screenings. The patients' clinical condition has the most important influence on posttransfusion increment.

Neurological involvement in acute myeloid leukaemia has become more common in recent years. The increase seems to be related to the longer survival rates made possible by more intensive treatment protocols. The predictive elements appear to be the tumour mass, cytomorphological variety M5, splenomegaly and serum LDH. Prophylaxis with craniospinal radiotherapy or spinal chemotherapy does not modify the course of the leukaemia or diminish the frequency of neuromeningeal complications. Six cases of AML involving the central nervous system were examined, two at onset and 4 at first relapse. Neuromeningeal complications are to be feared since they are extremely difficult to eradicate completely and the prognosis is extremely unfavourable especially if a bone marrow relapse occurs simultaneously.

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.

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.

CGL is a highly specific disease that is defined by strict hematologic parameters that include a pathognomonic differential leukocyte count. Usually CGL is accompanied by the presence, in bone marrow cells, of the Ph chromosome, the first chromosomal anomaly to be regularly associated with a human neoplastic disease. CGL is predominantly a disease of the productive middle years of life, which maximizes its adverse impact on family life and family economics. The disease is of worldwide distribution and there is a slight male preponderance. The disease is characterized by an initial chronic phase when it behaves as a differentiated neoplasm and responds very well to simple, nonintensive therapy. After a variable interval, CGL undergoes metamorphosis to a refractory phase that responds poorly or sometimes not at all to therapy, even when this is intensive. At the stage of metamorphosis a great variety of clinical and hematologic pictures occur, and CGL may mimic a myeloproliferative disease, a myelodysplasia, a subacute leukemia, AML, or ALL. The old concept of an abrupt, explosive transition from the chronic phase to a so-called blastic crisis is incorrect: this rarely occurs and in most patients who are carefully followed, CGL is observed to undergo two or more stepwise evolutions, eg, from chronic phase to an accelerated myeloproliferative phase to a phase that resembles AML. Many patients with CGL conform to an established pattern of clinical features. There is a history of insidious symptoms of anemia and of splenomegaly. The physical signs are those of pallor and marked splenomegaly, while the hematologic findings are of moderate anemia, moderate thrombocytosis, and a marked granulocytic leukocytosis with a specific differential count. The radiologic findings are typically normal. Diagnostic difficulty seldom arises with this classic presentation. The patient who is detected at an early stage of CGL may lack the history, physical signs, and fully developed hematologic picture of CGL. Before the availability of cytogenetic studies, the diagnosis could only be established with confidence by observing the patient until the typical features of the disease emerged. Also considered are the less frequent but important atypical presentations of CGL. The symptoms and complaints, findings on examination, complications and hematologic findings may depart from the typical case in a bewildering variety of ways, so that the diagnosis may be difficult, indeed, CGL is generally not the initial diagnosis that is made. When the patient with CGL has received treatment, it is usual for he or she to become asymptomatic, with no abnormal physical signs.(ABSTRACT TRUNCATED AT 400 WORDS)

The French-American and British (FAB) classification of 62 consecutive cases of acute myeloid leukemia was undertaken. AML-M2 was the commonest FAB type (32.26%), followed by M1 and M4 (22.58% each), M5 (8.6%) and M6 and M7 (1.61% each), respectively. One of the patients was diagnosed as AML-MO (not a FAB type). The mean age of M1, M2, M3 and M5 cases was between 25 and 29 years, whereas in M4 patients it was 45.6 years. AML-M2, M4 and M5 were commoner in males, M1 in females and M3 equal in both sexes. Feeling of weakness, easy fatiguability and pallor were invariably present in all FAB types. All the patients of M1 and M5, 85% of M2, 64% of M4 and 50% of M3 presented with fever. Bleeding manifestations were most frequent in M3 cases followed by M5, M1, M4 and M2, respectively. Hepatomegaly and splenomegaly were relatively less prominent features in M3 as compared to other FAB types. Amongst the haematological parameters, anaemia was more severe in M1, leucocytosis in M2 and thrombocytopenia in M3 cases as compared to other FAB types.

The results of autologous bone marrow transplantation (ABMT) in acute leukemia (AL) and the prognostic factors for outcome were analyzed in a series of 90 consecutive patients treated at a single institution (mean +/- SD age: 25 +/- 11 years). Diagnosis was: AML (n = 43), ALL (n = 44), acute undifferentiated leukemia (n = 2) and acute bilineage (n = 1). Disease stage at ABMT was: first complete remission (CR1) 46 cases, CR2 33, other stages 11. Conditioning consisted of cyclophosphamide and total body irradiation in 88 patients. The 3 year probability of disease-free survival (DFS) was influenced by disease stage at ABMT: CR1 48%, CR2 28%, CR3 plus CR4 15%. The characteristics associated with a high probability of relapse were: in AML a FAB subtype other than M1 or M3 (p = 0.01) and in ALL an interval between CR1 and ABMT of < 3 months (p = 0.002). A WBC > 15 x 10(9)/l at diagnosis (p = 0.01), splenomegaly at diagnosis (p = 0.002) and time to CR1 > 4 weeks (p = 0.06) increased the risk of relapse in the entire group in CR1. In multivariate analysis, WBC at diagnosis (p = 0.006) and disease stage at ABMT (p = 0.03) independently influenced DFS. This study confirms the encouraging results of ABMT in CR1 but further antileukemia measures are necessary in patients with adverse prognostic features.

Recombinant human (rh) granulocyte-macrophage colony-stimulating factor (GM-SCF) is currently being tested in clinical trials for the treatment of acute myeloid leukemias with two main intentions: reduction of neutropenia and recruitment of leukemic blasts into cell cycle to enhance cytarabine (ara-C) mediated cytotoxicity. We report a case of a fatal spleen rupture in a patient with acute monocytic leukemia (AML M5b) who was treated according to a clinical phase I/II protocol with rh GM-CSF priming and standard induction chemotherapy TAD 9 (thioguanine/ara-C/daunorubicin). During treatment we observed rapidly rising peripheral blast counts and the development of an acute abdomen. Ultrasound examination revealed splenomegaly due to diffuse cellular infiltration and spleen rupture. The patient died 17 days later due to pneumonia and renewed spleen hemorrhage. Bone marrow progenitor assays before treatment showed exclusive growth of monocytoid blast cell colonies (CFU-L). Colony growth could be stimulated with rh GM-CSF and blocked dose-dependently by a monoclonal anti-GM-CSF antibody. CFU-L proliferation also increased after stimulation with rh interleukin-3 (rh IL-3) and supra-additively with rh granulocyte colony-stimulating factor (rh G-CSF) combined with rh GM-CSF. Furthermore, rh GM-CSF induced surface marker expression of CDw 65 and CD 11b on isolated CFU-L blasts. After short-term suspension culture, rh GM-CSF enhanced the expression of CD 29- and CD 11b-adhesion molecules on peripheral blast cells. In summary, this case represents a fatal spleen rupture occurring during rh GM-CSF priming and induction chemotherapy for acute monocytic leukemia. Although the etiology of this spleen rupture remains uncertain, in view of our data we suggest special caution, when further testing this therapy protocol in acute leukemias with monocytic subtype and high peripheral blast cell counts.

A 58-year-old woman complicated with rheumatoid arthritis (RA) was admitted to our hospital with right axillar lymphadenopathy and splenomegaly in November 1992. She was diagnosed as an anaplastic large-cell lymphoma (Ki-1 +) (stage IIIB) on the histological findings of the right axillar lymph nodes. She was treated with 11 courses of CHOP regimen between February 1992 and May 1993, and with mitoxantrone, etoposide (VP-16) and predonisolone in April 1992 and May 1993. The right axillar lymph nodes and spleen were irradiated at a dose of 36Gy in October 1992 and May 1993 respectively. In May 1993, peripheral blood showed WBC 89,000/microliter with 96% myeloblasts, Hb 8.3 g/dl, and Plt 124,000/microliter. Bone marrow aspirate revealed hypercellularity with 90% myeloblasts, which were positive for CD13 and HLA-DR. She was diagnosed as AML (M1). The karyotype showed normal. Southern blot analysis did not reveal the rearrangement of the MLL gene. She received the BHAC-DMP regimen and obtained complete remission. However, she relapsed during consolidation therapy, and died of cerebral bleeding. An autopsy revealed absence of a residual tumor. The mean interval from exposure to alkylating agent to the onset of secondary leukemia has been reported to be about 5 years, in contrast to a shortened interval of about 2 years for VP-16-induced leukemia. In our patient, it took only 1 year to have AML following chemotherapy for Ki-1 lymphoma. This suggests that her AML might be induced not only by treatments for RA and Ki-1 lymphoma, but also by immunological background such as RA.

A 60-year-old Japanese woman was admitted to our hospital because of fatigue, weight loss and abdominal distension. Myelofibrosis was diagnosed, based on anemia, huge hepatosplenomegaly, leukoerythroblastosis and bone marrow fibrosis. Following treatment with ranimustine, anemia and splenomegaly improved. Seven months after initial therapy of ranimustine, however, polycythemia (RBC 7.39 x 10(6)/microliter; Hb 19.1 g/dl, Ht 65.9%) developed gradually, then RBC decreased to normal level following venesection (total 1,200 ml). After 32 months, blastic transformation occurred. The blasts were negative for myeloperoxidase. By flow cytometric analysis, the cells were positive for CD2, CD13, CD33 and HLA DR. Thus, AML (M0) was diagnosed. Despite of treatment with multicytotoxic agents, she died of DIC 36 months after the initial diagnosis of myelofibrosis. The progression from myelofibrosis to polycythemia is rare and only 15 cases have been reported so far. In addition, although a chromosomal abnormality, 46, XX, t(3; 12) (q25; p11), was present at the time of first diagnosis of myelofibrosis, the development of an additional abnormality, del(11) (q-), might be related to the transformation to AML.
