Cytogenetic responses of 11 chronic myeloid leukemic (CML) patients during the first chronic phase, treated with the combination of all-trans retinoic acid (ATRA) + interferon (IFN) were compared to 9 other CML patients of phase one, treated with interferon monotherapy. Metaphase and interphase cytogenetics and a semiquantitative polymerase chain reaction (PCR) were used to evaluate the cytogenetic responses. Two of the 11 patients in the ATRA + interferon treated group were withdrawn, one of them because of interferon intolerance, and the other because of compliance failure. Among the 9 ATRA + interferon treated patients 6 major cytogenetic responses could be detected and 3 of them were complete. Of the 9 patients treated with IFN monotherapy only 2 major cytogenetic responses could be registered. No severe adverse effects were observed. The first results suggest that the ATRA + interferon combination may be superior in achieving cytogenetic remission in the first chronic phase of CML.
