Abstract The properties of a rabbit antiserum (anti-AML) raised to a purified protein from membranes of human acute myelogenous leukemia (AML) cells is described. Bone marrow and peripheral blood leukocytes (PBL) from either normal individuals or patients with either myeloproliferative or other disorders were analyzed in a fluorescence-activated cell sorter (FACS IV) after labeling with anti-AML, normal rabbit serum (NRS), or antiserum raised to normal human membrane antigens. Of 40 cell samples from patients with acute myelogenous leukemia, 39 reacted strongly with the anti-AML antiserum. Similarly, all of 19 specimens from patients with chronic granulocytic leukemia reacted with the anti-AML. When 42 bone marrow or PBL samples from patients with a variety of lymphoproliferative disorders were examined, 2 specimens reacted with the antiserum, both from individuals with diagnoses of acute lymphocytic leukemia (ALL). None of the 14 normal bone marrow or PBL donor specimens tested reacted with the antiserum. It was also found that essentially all samples from patients in clinical remission from AML had high numbers of cells reactive with the anti-AML. When cells from such individuals were labeled and sorted on the FACS IV, it was found that cells fluorescing strongly with the anti-AML contained cells of both myeloid and lymphoid origin. The implications of these results are discussed.

Bone marrow transplantation has become an accepted treatment for severe aplastic anemia, acute myelogenous leukemia, and acute lymphocytic leukemia (20;35). Less commonly thalassemia (23), multiple myeloma (25), severe combined immune deficiencies (10), and chronic granulocytic leukemia (14) are also treated with marrow transplantation. Most donors are siblings whose HLA phenotype is identical to the patient's. Such donors, however, are available to only one third of patients (6;16;27;28;35). In the absence of an HLA-identical sibling, partially matched, haplo-identical, related donors (differing by only one major histocom-patibility antigen) can be found for another 7% of patients (1;6;27;37). A variety of lower quality matches also can be found but have not been used extensively. Advances in tissue typing and the treatment of graft versus host disease now allow physicians to consider matchedunrelatedindividuals as potential donors when a suitable related donor is not available (11;12;13;15;17;22).

Abstract Context.—The clinical association between loss of the Y chromosome and acute myelogenous leukemia and myelodysplastic syndrome (AML/MDS) has been debated because both phenomena are related to aging. A prior publication suggests that loss of the Y chromosome in more than 75% of cells may indicate a clonal phenomenon that could be a marker for hematologic disease. Objective.—To evaluate the relationship between loss of the Y chromosome and AML/MDS. Design.—A retrospective review of cytogenetic reports of 2896 male patients ascertained from 1996 to 2007 was performed. Results were stratified based on the percentage of cells missing the Y chromosome and were correlated with patients' ages and bone marrow biopsy reports through logistic regression analysis with adjustment for age. Results.—Loss of the Y chromosome was found in 142 patients. Of these, 16 patients demonstrated myeloid disease, with 2 cases of AML and 14 cases of MDS. An increased incidence (P < .05) of AML/MDS was seen only in the group composed of 8 patients with complete loss of the Y chromosome in all karyotyped cells (1 case of AML and 7 cases of MDS). Conclusion.—Loss of the Y chromosome appears to be primarily an age-related phenomenon. However, in individuals in which all cells on cytogenetic analysis showed loss of the Y chromosome, there was a statistically significant increase in AML/MDS, suggesting that the absence of any normal-dividing cells in a bone marrow analysis may be indicative of AML/MDS.

PURPOSE This study was conducted to assess the comparative values of allogeneic bone marrow transplantation (BMT) and autologous bone marrow transplantation (ABMT) with sequential postremission chemotherapy (SPC) in children with acute myelogenous leukemia (AML) in first remission. PATIENTS AND METHODS From March 1987 to March 1990, 161 assessable patients younger than 15 years of age with newly diagnosed AML were treated uniformly with two courses of daunorubicin and standard-dose cytarabine. After initial consolidation with a course of daunorubicin, cytarabine, and thioguanine (DAT), patients in complete remission (CR) were randomized to receive either ABMT or SPC, except for those with an HLA-matched sibling who were assigned to undergo BMT. SPC consisted of three additional courses of DAT, followed by three pairs of drugs administered sequentially for a total of six cycles. RESULTS Overall, 127 of 161 patients attained CR (79%). The estimated probabilities of survival and event-free survival (EFS) at 5 years for all patients were 42% and 25%, respectively (median follow-up, 28 months). For the 127 complete responders, the 5-year probability of disease-free survival (DFS) was 31%, with a cumulative risk of relapse of 64%. For the purpose of this study, all complete responders were evaluated for analysis of disease outcome according to the intent-to-treat principle, regardless of whether they actually received the intended therapy. The 5-year DFS was 51% for the BMT group (n = 24), significantly higher (P = .03) than that observed for the other cohorts: 21% for ABMT (n = 35), 27% for SPC (n = 37), and 34% for a group of 31 nonrandomized (NR) patients. Bone marrow relapse was the most frequent cause of postremission failure in all therapeutic subgroups, including the BMT cohort, in which no deaths attributable to the toxicity of the procedure were recorded. CONCLUSION The results of this study show that BMT is more effective than ABMT or SPC in preventing leukemia relapse and extending DFS duration in children with AML in first remission.

PURPOSE One of the goals of study AMA-BFM-87 was to test prospectively in acute myelogenous leukemia (AML) patients if cranial irradiation could be replaced by late intensification therapy with high-dose cytarabine (Ara-C) and etoposide (VP-16). PATIENTS AND METHODS Patients with a low risk of CNS relapses (ie, no initial CNS disease, WBC count at diagnosis < or = 70.000/microL) were randomized for irradiation (group A, 31 patients). In 25 patients (group B), randomization was refused. As interim results showed no increase of CNS relapses in nonirradiated patients, prophylactic irradiation was discontinued after 2 1/2 years to prevent unnecessary CNS toxicity. Forty-four patients (group C) entered the study after randomization had been stopped. RESULTS In all patients with a low risk of CNS recurrences (n = 100), a significantly higher probability of relapse-free interval (pRFI) of 5 years was found in irradiated patients (pRFI = .78) compared with nonirradiated patients (pRFI = .41) (P = .007). Moreover, a slightly higher incidence of CNS relapses was observed in nonirradiated patients. Due to the small number of patients, this was not observed when randomized patients only were analyzed. In accordance with these findings, the favorable outcome of low-risk patients in the preceding study, AML-BFM-83 (pRFI > .80), could only be reproduced in study AML-BFM-87 in patients who had received cranial irradiation. CONCLUSION These results indicate that cranial irradiation should be an integral part of the treatment of all AML patients not undergoing bone marrow transplantation. Residual blasts in the CNS may escape systemic chemotherapy and lead to recurrence of the initial disease not only in the CNS, but also in the bone marrow.
