Data are provided as number (%) of patients. Cytogenetic response was defined by the prevalence of Ph+ metaphases: CCyR, 0% Ph+; PCyR, 1% to 35% Ph+; minor CyR, greater than 35% to 65% Ph+; minimal CyR, greater than 65% to 95% Ph+; no response, greater than 95% Ph+.

CyR indicates cytogenetic response; MCyR, major cytogenetic response; CCyR, complete cytogenetic response; PCyR, partial cytogenetic response.
