Summary
Childhood acute lymphocytic leukemia (ALL) therapy has advanced, offering cures for some. Key challenges include late treatment effects and preventing drug-resistant relapse for better outcomes.
Area of Science:
- Pediatric Oncology
- Hematology
- Clinical Therapeutics
Background:
- Acute lymphocytic leukemia (ALL) therapy has evolved significantly over three decades.
- Cure is now a realistic goal for a subset of children diagnosed with ALL.
- Long-term survival highlights late consequences of disease and treatment as critical concerns.
Purpose of the Study:
- To review the evolution of ALL therapy and identify current challenges.
- To emphasize the need to address late treatment sequelae, particularly impaired intellectual performance.
- To highlight the critical issue of bone marrow relapse and drug resistance.
Main Methods:
- Review of accumulated evidence from three decades of ALL therapy evolution.
- Analysis of late consequences of disease and therapy in long-term survivors.
- Examination of factors contributing to bone marrow relapse and drug resistance.
Main Results:
- Therapy for childhood ALL has progressed rationally, with increasing cure rates.
- Impaired intellectual performance, potentially linked to CNS prophylaxis, is a significant late consequence.
- Bone marrow relapse, often due to drug-resistant cells, remains a major obstacle with poor prognosis.
Conclusions:
- Future ALL treatment protocols must balance effective central nervous system (CNS) leukemia control with minimal neurotoxicity.
- Individualized therapeutic strategies based on relapse risk prediction are essential.
- Further research into the mechanisms and prevention of drug resistance is crucial for improving cure rates.
