Analysis of clinical profile and role of various prognostic factors in early bone marrow response in children with acute lymphoblastic leukemia treated by Modified Multicenter Protocol (MCP) 841 protocol: Experience from a tertiary care center in North India.
Indian Journal of Cancer 2023 October 2
BACKGROUND: It is important to study the clinical profile of pediatric patients with acute lymphoblastic leukemia (ALL) and assess various prognostic factors implicated in response to induction chemotherapy for optimal treatment outcomes in India. The present study was done to evaluate the clinical profile and to find the correlation of day 7 and day 28 marrow blast response with already established prognostic factors in children with ALL in the region of North India using MCP 841 protocol for all patients.
METHODS: A total of 60 children up to ages 14 years with ALL were given treatment in the form of induction remission (MCP-841 protocol) I1 cycle (induction 1) therapy for 29 days. Complete hemogram for blast cells and bone marrow examination (bone marrow aspiration and, if required, bone marrow biopsy) was done on days 7 and 28 (completion of I1 cycle) to see early bone marrow response. Early response to induction therapy was compared in patients with and without high-risk factors, and results were analyzed statistically.
RESULTS: Out of 60 enrolled children, 56 (93.4%) patients were in complete remission at the end of induction 1 cycle. Various risk factors were found to be of prognostic significance in first remission and early response to induction therapy were initial total leukocyte count (TLC) at presentation, immunophenotype of ALL; while other factors including age and sex was not found to be significant.
CONCLUSION: Prevalence and significance of various prognostic factors implicated in pediatric ALL tend to be different in various populations. A better understanding of such factors in these populations will help in the tailoring of risk-adapted treatment protocols to local needs.
