Correlations between Ph 1 clone and leukocyte alkaline phosphatase on their associaton: chronic myeloid leukemia and pregnancy]

A biological [karyotype, leucocyte alkaline phosphatase (L.A.P.), haematimetry] and clinical study was performed on three women carriers of a chronic myaloid leukemia during their pregnancy (3 1/2 months, 6 1/2 months), or just after delivery. The results show : (1) a relation between the acuteness of the illness and a higher rate of L.A.P., probably secondary to pregnancy, and (2) a relation between the clinical evolution and the rate of Ph1 (+) cells.
