Biphenotypic leukaemia: a case of mixed T lymphoblastic and myeloblastic leukaemia.

Gene variants of CYP1A1 and CYP2D6 and the risk of childhood acute lymphoblastic leukaemia; outcome of a case control study from Kashmir, India

Studies on associations of various polymorphisms in xenobiotic metabolizing genes with different cancers including acute lymphoblastic leukaemia (ALL) are mixed and inconclusive. The current study analyzed the relationship between polymorphisms of phase I xenobiotic metabolizing enzymes, cytochromes P450 1A1 (CYP1A1) and CYP2D6 and childhood ALL in Kashmir, India. We recruited 200 confirmed ALL...

[Biphenotypic acute leukaemia: case reports of two paediatric patients].

INTRODUCTION Biphenotypic acute leukaemia is an uncommon type of leukaemia whose blasts co-express myeloid and B-or T-lymphoid antigens. CASE REPORT We describe two cases of paediatric patients with biphenotypic acute leukaemia. A four-year-old female patient was found to have myeloid and B-lymphoid associated antigens in the same blast cells. Cytogenetic analysis showed a Philadelphia (Ph) p...

Acute biphenotypic leukaemia: immunophenotypic and cytogenetic analysis.

The incidence of acute biphenotypic leukaemia has ranged from less than 1% to almost 50% in various reports in the literature. This wide variability may be attributed to a number of reasons including lack of consistent diagnostic criteria, use of various panels of antibodies, and the failure to recognize the lack of lineage specificity of some of the antibodies used. The morphology, cytochemist...

Daunorubicin in acute leukaemia.

Daunorubicin has been used in the treatment of six cases of acute lymphoblastic and thirteen cases of acute myeloblastic and mono-myeloblastic leukaemia. Complete remissions were obtained in eight patients, three with acute lymphoblastic leukaemia and five with acute myeloblastic leukaemia. Marrow aplasia makes the drug difficult to administer, but no patients died from this cause, in this seri...
