In 22 patients with acute myeloid leukaemia (17 cases of myeloblastic leukaemia, 4 cases of myelomonocytic leukaemia and 1 case of undifferentiated-cell leukaemia) platelets were isolated from the plasma by the method of Nicholls and Hampton as modified by Levy-Toledano by centrifugation in albumin gradient. The aim of platelet isolation was their "concentration" in cases of thrombocytopenia to values making possible aggregation tests, and platelet separation from the influence of plasma factors. Then aggregation of isolated platelets caused by ADP was studied. In 16 out of 22 patients a fall of aggregation was observed, with the mean values of aggregation rate and intensity were significantly lower. Parallelly done determinations of aggregating activity released from the platelets by thrombin showed lower values as compared with platelets from healthy subjects. In might be thought, in this connection, that the demonstrated reduction of isolated platelets is associated with a diminution of the nucleotide pool or disturbances of the platelet release reaction. The disturbances of the platelet release reaction. The disturbances of aggregation of isolated platelets and reduction of the aggregating activity were most pronounced in acute myelomonocytic leukaemia.

A patient is reported to have an in between type of acute myeloid leukaemia, namely acute eosinophilomyelomonocytic leukaemia. The blasts in the peripheral blood showed a definite transition towards immature monocytes. The bone marrow contained 65% blasts and 13% eosinophil promyelocytes. The large number of immature eosinophils in the bone marrow strongly support the view that they were part of the leukaemic process and not merely a reactive eosinophilia.

Acute myelogenous leukaemia was diagnosed within a 1 week's interval in a married couple without consanguinity. The husband had acute myelomonocytic leukaemia whereas the wife had acute myelogenous leukaemia of the classical type. Neither the histories nor findings contributed to an understanding of leukaemogenesis. The calculated risk that a husband and wife should develop acute myelogenous leukaemia within the same year is approximately 1:400 millions.

Daunorubicin, thioguanine and cytosine arabinoside were administered from the 17th to 34th weeks of pregnancy in a 23-year-old patient with acute myeloid leukaemia. The patient went into remission of her leukaemia, and a normal male infant was born after labour was induced in the 40th week. This experience supports the view that modern regimens of anti-leukaemic drugs may be administered during the second and third trimesters of pregnancy without harmful effects on the foetus.

The blast cells of 19 patients with Ph1-positive chronic granulocytic leukaemia (CGL) in blast crisis (BC) were studied by means of several techniques: morphology, cytochemistry, ultrastructure, surface markers and the enzyme terminal transferase. Cells of BC were, in most case, extremely undifferentiated by morphology and cytochemistry. Our data showed that in 80% of cases the cells in BC were myeloid and in 20% they were "lymphoblastic". The M1, M2 and M3 forms (FAB classification) were rare in CGL BC compared with acute myeloid leukaemia (AML). A megakaryoblastic type was seen in 15% of BC cases; the existence of this form could only be demonstrated by electron microscopy. The limphoblastic BC cells were, as in acute lymphoblastic leukaemia (ALL), positive with Greaves' anti-ALL serum and had elevated levels of terminal transferase. A case of a 17-year old boy presenting as ALL, reverting to chronic-phase CGL after complete remission and developing terminally a myeloid BC is described in detail. This case helps to illustrate a new form of natural history of CGL unveiled by the present study.

Out of 64 consecutive unselected patients with acute myeloid leukaemia studied during 1973-6, five developed clinical evidence of spread to the central nervous system (CNS). Neuroradiological examination showed cerebral deposits in three, in whom rapid symptomatic relief was obtained with radiotherapy. In two of these patients who developed solid intracranial deposits haematological remission could be reinduced or maintained; they were still alive 86 and 134 weeks later. When patients presented with spread to the CNS complicating generalised uncontrolled leukaemia they had short survivals. CNS infiltration may respond dramatically to appropriate treatment provided that it is not associated with generalised uncontrolled leukaemia, which has a poor prognosis. In view of this, routine "prophylaxis" of the CNS in adult acute myeloid leukaemia does not seem justified at present.

Of 50 consecutive patients admitted with acute myelogenous leukemia, 30 developed complete remissions on antileukemic therapy. Nineteen of the 30 repeatedly had elevated serum glutamic oxalacetic transaminase (SGOT) concentrations 3 to 14 weeks after the start of therapy. Patients with SGOT elevations had a significantly greater chance of remission and a longer survival (76 +/- 11 weeks) than those with normal SGOT levels (39 +/- 5 weeks), suggesting that hepatitis may have a beneficial effect in acute myelogenous leukemia. The hepatitis was mild in all patients. Review of patients at this institution alive 2 years after the diagnosis of acute myelogenous leukemia showed that they repeatedly had elevated SGOT levels. We believe that most had non-A, non-B post-transfusion hepatitis, which may have a beneficial effect on the leukemia or serve as an indicator of patients who have greater immunocompetence and thus a better prognosis.

Tn polyagglutination (persistent mixed-field polyagglutination) was detected in the blood of a 66-yr-old male laborer at the time of a splenectomy for life-threatening thrombocytopenia. Confirmation that the polyagglutination was caused by Tn activation was established by the use of lectins, by failure of the patient's red cells to react with sera from other patients with Tn polyagglutination, by weak aggregation with polybrene, by low red cell sialic acid levels, and by the persistence of polyagglutination over several years of testing. Two years after the discovery of the Tn polyagglutination, the patient developed acute myelomonocytic leukemia. Vigorous chemotherapy regimens resulted in clinical remission of the leukemia and the Tn polyagglutination. This report describes the first known case of Tn polyagglutination preceding the development of acute myelogenous leukemia.

DNA complementary to Moloney murine leukemia viral RNA was annealed with DNA isolated from peripheral leukocytes of twelve patients with leukemia. Six to 10% of the complementary DNA annealed to the DNA of one patient with acute myelogenous leukemia. The level of annealing of the complementary DNA to the other leukemic DNA's did not differ significantly from that to normal human spleen DNA. This result is consistent with reports of occasional positive results from other laboratories, but the significance, especially in reference to a causal role for RNA tumor viruses in human leukemia, remains unclear.

We report female monozygous twins who developed acute lymphoblastic leukemia at the age of 5 1/2 years. The diagnosis in the first twin was made after pallor, lethargy, and petechiae developed. The diagnosis in the second twin was made two days later when a whole blood count was taken. The lymphoblasts of both patients showed with the exception of the PAS-reaction identical morphological, cytochemical, and immunological results. The PAS-reaction was positive in 55% of the lymphoblasts in one twin, negativ in the lymphoblasts of the other twin. Both patients are in continuous complete remission 14 months after diagnosis. The risk of leukemia is high in the other monozygous twin when one of the twins has already developed leukemia. In the literature it is estimated to be 1 : 5. The diagnosis after the second year of life is rarely made at the same time. There is only one previous report of this occuring in a case of acute myeloblastic leukemia in 4 1/2 year old monozygous twins.
