    Abstract:
    With the rationale that a significant reduction of the malignant clone in CML might prolong time to metamorphosis, intensive treatment was given to patients < or = 55 years. Six months of hydroxyurea and high dose interferon-alpha (IFN-alpha) was followed by one to three courses of intensive chemotherapy. Patients who had a donor were allotransplanted and patients who became Ph-negative in bone marrow were autotransplanted. On 1 May 1995, 160 patients were registered in the study. Fifty-one percent of the patients who received six months IFN-alpha and hydroxyurea had a significant Ph-reduction and 5% became Ph-negative. The corresponding figures after two intensive chemotherapy courses were 47 and 28%, respectively. Twenty-seven of 30 autotransplanted patients have been analysed for Ph. Seventeen have relapsed cytogenetically, while ten are Ph-negative 1-64 + months after ABMT. BMT was performed in 59 patients. The actuarial 6-year survival from diagnosis of all 160 registered patients is 68%, which seems to be better than for age-matched historical controls.
