Decreased neutrophil alkaline phosphatase (NAP) synthesis is a classical feature of Philadelphia (Ph) positive chronic phase chronic myeloid leukemia (CML). Whether this aberration is an integral leukemic property of the cell or results from mediation by other factors is unclear. During a-interferon (α-IFN) based therapy the relationship between Ph chromosome suppression and NAP synthesis was examined. Four categories of response were observed in 19 patients studied sequentially. Significantly, persistent low NAP activity was observed in one patient in complete cytogenetic remission, while a second group of 7 patients demonstrated normal NAP activity in spite of persistence of the Ph chromosome in 100% of metaphases. In the absence of various clinical influences that can modulate NAP activity in chronic phase CML, the results reinforce the observation that the BCWABL fusion gene product is not a key factor influencing NAP activity in CML. |
