Application of Next-Generation Sequencing-Based Mutational Profiling in Acute Lymphoblastic Leukemia

Area of Science:

• Hematologic oncology
• Molecular diagnostics
• Genomic medicine

Background:

• Hematologic cancers are increasingly characterized by genetic and molecular profiling using next-generation sequencing (NGS).
• Understanding the advantages and limitations of NGS is crucial for its effective application in clinical decision-making.

Purpose of the Study:

• To identify opportunities within adult acute lymphoblastic leukemia (ALL) where mutational data can enhance disease biology understanding and patient care.
• To review the role of NGS in characterizing ALL and its potential clinical applications.

Main Methods:

• Review of recent advancements in NGS applications for hematologic malignancies.
• Analysis of NGS-based measurable residual disease (MRD) assessment in ALL.
• Examination of germline mutations in familial ALL cases.

Main Results:

• NGS-based MRD assessment is a sensitive and specific tool for monitoring ALL treatment response.
• Mutational profiling has revealed complex signaling pathways in T-cell ALL pathogenesis.
• Novel germline mutations predisposing to ALL have been identified in familial clusters.

Conclusions:

• Despite the utility of NGS in other hematologic malignancies, adult ALL patients currently lack integrated molecular prognostication schemas.
• Ongoing research aims to enhance the molecular toolkit for adult ALL, guiding therapy, response monitoring, and relapse detection.
