Acute Lymphoblastic Leukemia with Central Nervous System Involvement-Challenges in Management

Area of Science:

• Hematology
• Oncology
• Pediatric Oncology

Background:

• Significant advancements in acute lymphoblastic leukemia (ALL) treatment over six decades have improved patient survival.
• Improvements stem from enhanced diagnostics, risk stratification, supportive care, and novel therapies like immunotherapy and targeted therapy.

Purpose of the Study:

• To address persistent questions regarding central nervous system (CNS) involvement in ALL.
• To review diagnostic approaches, treatment strategies, and challenges in low- and middle-income countries (LMICs).

Main Methods:

• Review of current clinical trial data for treatments targeting CNS activity in ALL.
• Analysis of risk factors and relapse patterns associated with CNS leukemia.
• Examination of treatment considerations specific to LMICs.

Main Results:

• While overall survival has improved, CNS leukemia remains a critical area requiring further research and optimized management.
• Current data highlight the need for refined strategies to prevent CNS relapse and manage existing CNS disease.
• Treatment disparities and specific challenges exist for patients in LMICs.

Conclusions:

• Further research is essential to fully understand and manage CNS involvement in ALL.
• Optimized treatment protocols are needed to reduce CNS relapse rates and improve outcomes.
• Addressing challenges in LMICs is crucial for equitable ALL care globally.
