The objective of this study was to investigate the prognostic impact of the reduction of Philadelphia chromosome (Ph) positive metaphases by treatment of chronic myelogenous leukaemia (CML) with interferon (IFN) alpha. Therefore, we evaluated the outcome of patients with previously untreated chronic phase Ph-positive CML, enrolled from 1984 to 1990 into two consecutive IFN trials at our institution. Of a total of 71 patients, 62 (87%) were evaluable for cytogenetic response. No cytogenetic improvement was seen in 16 patients (23%), 28 patients (38%) had a decrease in Ph-positive bone marrow metaphases to levels ranging from 35% to 95%, and nine patients (13%) to levels between 5% and 34%. In nine patients (13%), Ph-positive metaphases were no longer detectable. After a median follow-up period of 33 months, the projected 5-year survival is 55% for the 62 patients evaluable for cytogenetic response. In this patient population there was no significant difference in the survival probability according to patients' risk status as defined by the Sokal score. Categorization according to the extent of Ph reduction, however, allowed three groups with significantly different prognoses to be identified. Patients achieving a Ph reduction to less than 35% were found to constitute a low risk group with a median survival not yet known and a projected 5-year survival of 90%. The 5-year survival rate was 55% for patients with a Ph reduction to levels between 35% and 95%, and less than 10% for those without any cytogenetic improvement. Thus, this study demonstrates that cytogenetic improvement on IFN treatment is an important prognostic factor for survival.
