Direct detection of the Philadelphia chromosome in CD20-positive lymphocytes in chronic myeloid leukemia by tri-color immunophenotyping/FISH

Leukemia. 1994 Nov;8(11):1940-3.

Abstract

Six patients with previously diagnosed chronic myelogenous leukemia (CML) were studied by a tri-color immunophenotyping/FISH method for direct determination of the Philadelphia (Ph) chromosome in B and T lymphocytes. Two patients had involvement of CD20-positive lymphocytes. CD3-positive lymphocytes in all patients were negative for the Ph chromosome.
