Abstract
Chronic myelogenous leukemia (CML) is a rare disease in children, accounting for approximately 3% of leukemias in children and adolescents, with an annual incidence of 1 case per million children in western countries. This study was conducted, at PGIMER, Chandigarh. Ninety eight patients, 48 in children and adolescents group, and 50 in adult group were included in the study. Their hematological profiles along with the bone marrow findings were analyzed. The diagnosis of CML was confirmed by cytogenetics and/or molecular analysis. The complete hematological response (CHR) was analyzed at 3months and cytogentic response (CgR) at 12months after starting imatinib therapy. Compared to adults, pediatric and adolescent patients were more symptomatic at presentation (93.5 vs. 75%). Among symptomatic patients, massive splenomegaly (>10cm), higher total leucocyte and platelet counts were seen more frequently in pediatric patients. The most common transcript in both groups was e14a2. The distribution of pediatric and adolescent cases in Sokal, Hasford and EUTOS score, showed only statistically significant difference for low risk Sokal group, which had more patients in pediatric group. Compared to adults, pediatric and adolescent patients had similar CHR rate (91.3 vs. 92%), but showed lesser major CgR rate (90.9 vs. 95.5%) however, this was not statistically significant.
