Abstract Imatinib mesylate is currently considered the first-line treatment for chronic myeloid leukemia (CML). Sokal, Hasford and EUTOS are the three major risk categorization scores available for CML patients. The present study aimed to explore the influence of three risk score, genetic polymorphisms of ABCB1, OCT1, ABCG2 and trough level concentration on complete cytogenetic response at 1 year and overall survival. The mean time period of follow-up was 53.05 months, and the overall survival was 94.6\%. The Sokal score (P 0.014), Hasford score (P 0.016) and MDR1 C3435T (P 0.001) tend to influence the overall survival in the patients. The patients who had better overall survival had early complete cytogenetic response (P 0.0003). The ABCG2 C421A was the covariate which had correlation with the complete cytogenetic response. A perceptive approach incorporating pharmacogenetic evaluation with major risk categorization score at the initial stage will help in ensuring better treatment success in CML patients treated with imatinib.
