In chronic myelogenous leukemia (CML) the Philadelphia (Ph)chromosome originates from a reciprocal translocation, t(9;22)(q34;q11),1that generates a chimeric BCR-ABL gene.2 The disease is incurablewithout bone marrow transplantation. In some cases, intensivechemotherapy3,4 or treatment with interferon alfa can suppressthe Ph-positive clone in the bone marrow,5,6,7 but the detectionof residual disease by the polymerase chain reaction (PCR) inpatients with a complete cytogenetic response suggests incompleteeradication of these cells.8
Few cases of Ph-positive CML have been reported in which a long-termremission occurred without treatment.9,10,11 We describe a patientwith Ph-positive CML who entered a lengthy . . . [Full Text of this Article]
