T-lymphoblastic leukaemia: a distinct variant of acute leukaemia.
نویسندگان
چکیده
Two cases of acute lymphoblastic leukaemia (A.L.L.) of T-cell type are reported. Clinically they were characterized by very high peripheral blood blast cell counts at presentation, the early development of meningeal leukaemia, and relative resistance to treatment with combination chemotherapy. Leukaemic cells from both patients lacked all the B-cell markers investigated, but 60-65% of their cells formed rosettes with sheep red cells. Cytochemical and surface structure studies helped to define additional features of these cells and confirmed their T-cell nature.It seems that this variant of A.L.L. may not be uncommon and that it can be distinguished on clinical and immunological grounds from the usual type of A.L.L. which runs a less aggressive course and lacks B- or T-cell markers.

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...

Background: Immunophenotypic characterization of the leukemic cells has been widely used as a tool for diagnosis, classification, stratification and prognosis of leukaemia. Objective: To investigate the immunophenotypic subtype profiles of Iranian patients with acute lymphoblastic leukemia (ALL) and its association to disease outcome. Methods: In this study, a total of 60 Iranian patients with ...
متن کاملA Case of Bickerstaff Brainstem Encephalitis and Acute Lymphoblastic Leukaemia
Bickerstaff Brainstem Encephalitis (BBE) is a post-infectious immune disorder. It is rare, yet the most severe variant of Guillain-Barre Syndrome (GBS) in terms of initial presentation. Moreover, the coexistence of BBE and Acute Lymphoblastic Leukaemia (ALL) is distinctly uncommon. We report a case of a patient with a background history of Precursor B cell Acute Lymphoblastic Leukaemia (pre B A...
متن کاملCytochemical profile of B and T leukaemic lymphocytes with special reference to acute lymphoblastic leukaemia.
The PAS and acid phosphatase reactions showed a different pattern of positivity in the cells of lymphoproliferative disorders according to their B or T cell nature. In B-cell leukaemias (chronic lymphocytic and prolymphocytic) a low proportion of lymphocytes gave a positive result with the acid phosphatase reaction, while the majority were PAS positive in granular form. In contrast, in the T-pr...
