Methods: Forty eight chronic myeloid leukemia patients carrying variant translocations and treated with imatinib at our institute were considered for the study. Survival and response rates were evaluated. Results: The median follow up was 48 months(m). Forty three (89.58\%) patients achieved complete hematologic response. Thirty one (64.58\%) patients achieved complete cytogenetic response and 19(39.58\%) achieved major molecular response anytime during their follow up period. Only 18.75\% of the patients achieved complete cytogenetic response and major molecular response within the stipulated time frames.The estimated overall survival at 48 m median follow up was 81.2\%.The progression free survival was also 81.2\% and the event free survival was 79.1\%.There was no significant survival difference between low vs intermediate and high risk sokal group. Conclusion: We report suboptimal responses to imatinib in chronic myeloid leukemia with variant translocations. Further studies with imatinib and the newer more active drugs dasatinib and nilotinib are justified.} }
