Lymphoid Cell Surface Markers in Acute Lymphocytic Leukaemia

Abstract
Peripheral blood lymphoid cells of 29 patients with acute lymphocytic leukaemia (ALL) at onset were studied for characterization of B and T membrane markers and phytohaemagglutinin responsiveness. 24 cases (83%) were classified as ‘null’ cell ALL and 5 (17%) as T‐cell ALL. No relationship could be found between cytological presentation and immunological classification. Moreover, no correlation has been demonstrated between clinical‐immunological parameters and prognosis, indicating that in our series of patients, assessment of cell size and surface markers were not a reliable predictor of prognosis.
