In a 45-year-old woman with severe normochromic
anemia
(Hb 2.8 g%) an extensive myelofibrosis and infiltration of the bone marrow with small blasts was observed histologically. Cytochemical examination of the blasts showed a negative peroxidase and a strongly positive alpha-NE reaction. PAS reaction was slightly granular positive in the cytoplasmic protuberances of the blasts and in the platelets. Marker analysis yielded no evidence of lymphatic origin of the blasts. In flow-cytometric studies of 230,000 cells a homogeneous 2c blast population could be identified. Cytogenetic analysis revealed an abnormal pseudo-diploid karyotype characterized by 2 acrocentric marker chromosomes caused by a translocation of chromosomes 8 and 14, as usually seen in Burkitt type lymphoma. Finally the reaction product of platelet-specific peroxidase could be demonstrated in the perinuclear cisternae of the endoplasmic reticulum by electron microscopy. Highly elevated beta-thromboglobulin and platelet factor 4 plasma levels were also measured. Following an ineffective treatment with daunoblastine and
ARA-C
, the patient died of pseudomonas aeruginosa septicemia after having received high-dose
ARA-C
treatment.

Twenty-nine late chronic and accelerated phase chronic myelogenous leukaemia (CML) patients were entered in a pilot study designed to test the therapeutic efficacy of treatment with interferon-alpha (IFN-alpha) and low-dose cytosine arabinoside (
ARA-C
). IFN-alpha was administered at a dose of 2-10 x 10(6) IU/day and
ARA-C
at 15 mg/m2/day for 14 days each month. The treatment was well tolerated by 73% of the patients. Side effects were mainly asthenia, anorexia,
anaemia
and piastrinopenia. Haematological and cytogenetic responses were evaluated in the 19 patients who received more than 6 cycles. Four complete haematological response, 7 partial haematological response, 6 minor haematological response, 2 stable disease were obtained in this patient group. Two complete cytogenetic responses and 2 minor cytogenetic responses were detected in these patients. Suppression of secondary Ph' positive clones which appeared during the previous IFN-alpha treatment was documented in 3 accelerated phase patients after
ARA-C
was added to their IFN-alpha treatment. It would therefore seem that late chronic and accelerated phase CML patients benefit from combined IFN-alpha/
ARA-C
treatment and achieve haematological and cytogenetic responses not obtained during previous treatment without being exposed to undue toxicity. However, we cannot judge whether it offers any advantage in terms of survival.

We report a new case of therapy-related acute myeloid leukemia in a child with Langerhans cell histiocytosis. This patient was previously treated with a protocol of multidrug chemotherapy, containing a relatively low dose of etoposide (total dose of 900/m(2)). Twenty-six months after the end of the therapy, the patient returned to the hospital with fever and
anemia
. The white blood cell count was 53 x 10(9)/L. The bone marrow examination showed massive infiltration with French-American-British acute myeloid leukemia classification M4 blast cells. The patient did not respond to an intensive treatment with high dose
ARA-C
and idarubicin. He died 6 months later. The cytogenetic abnormality of the blast cells was a t(11;11)(p13 -15;q23), that has not been described before in a secondary leukemia case.

Treatment of acute leukaemia in adult Jehovah's Witnesses (JW) is challenging because of 'a priori' refusal of most physicians to apply diagnostic and therapeutic procedures to haematological abnormalities resembling acute leukaemia. Rejection of blood transfusions by individuals of this faith is usually blamed to justify this attitude, thus leading to severe personal, medical and psychological distress related to the lack of care. We therefore intended to verify whether a standard (tailored) chemotherapy, without the use of prophylactic blood product transfusions, could be applied during treatment of acute leukaemia under such circumstances. Eleven consecutive JW adult patients with acute leukaemia, all of whom had been denied care in other institutions, were treated at the European Institute of Oncology (EIO) in Milan, Italy. Five had acute lymphoblastic leukaemia (ALL) (one bcr/abl positive), six had acute myeloid leukaemia (AML) with immunophenotype and/or cytogenetic intermediate-high risk features, except one patient with acute promyelocytic leukaemia (APML). Standard induction chemotherapy [cytosine arabinoside (
ARA-C
) and daunorubicin (DNR) for AML, vincristine (VCR), DNR and prednisone (PDN) for ALL, all-trans retinoic acid (ATRA) and DNR for APML] with the antracycline dose of at least 30 mg/sqm were used. All patients experienced severe
anaemia
after induction chemotherapy despite erythropoietin. Median haemoglobin nadir for patients with ALL and AML was 4.5 g/dL (range 1.3-6.9) and 5.1 g/dL (range 2.6-6.8), respectively. Median platelet nadir counts for all patients was 14.5 x 10(9))/L (range 1-24). One patient died during induction probably due to haemorrhage. Four of five patients with ALL achieved a complete remission (CR) (including the bcr/abl case) while among patients with AML only the one with APML achieved CR. Three patients (APML = 1 and ALL = 2) are still alive and disease-free. This small series of adult patients with leukaemia illustrates difficulties in treating patients who are practising JW, yet nevertheless provides a significant argument against the prejudicial decision leading to evasion of treatment in these patients.
