Towards precision medicine in lymphoid malignancies.

Area of Science:

• Hematology
• Oncology
• Genomics

Background:

• Histopathology is crucial for diagnosing lymphoid malignancies, a diverse group of cancers.
• Genomic and epigenomic research has advanced the understanding of these tumors.
• While not entirely specific, certain genetic alterations are common in specific lymphoma types.

Purpose of the Study:

• To review clinically relevant diagnostic, prognostic, and predictive biomarkers in common B-cell malignancies.
• To explore how molecular profiling assays can enable precision diagnostics and medicine.
• To discuss future directions, including single-cell sequencing and omics technologies.

Main Methods:

• Review of current literature on genomic and epigenomic characterization of B-cell malignancies.
• Analysis of diagnostic, prognostic, and predictive biomarkers.
• Discussion of emerging technologies like single-cell sequencing.

Main Results:

• Recurrent genomic alterations provide complementary diagnostic information.
• Specific alterations serve as prognostic and predictive markers, guiding treatment decisions.
• Comprehensive molecular profiling supports precision diagnostics in B-cell malignancies.

Conclusions:

• Integrating molecular data with histopathology improves lymphoma diagnosis and management.
• Precision medicine approaches, guided by genetic biomarkers, are becoming integral to treating B-cell malignancies.
• Future research using advanced omics technologies will further elucidate clonal dynamics and evolution.
