Molecular techniques in haematopathology: what and how?

Area of Science:

• Hematopathology
• Molecular Diagnostics
• Oncology

Background:

• Accurate diagnosis of lymphoid and myeloid neoplasms is crucial for effective treatment.
• Molecular techniques play an increasingly vital role in hematopathological diagnostics.
• Unequal access to advanced molecular testing resources presents a significant challenge globally.

Purpose of the Study:

• To provide a comprehensive overview of molecular techniques for diagnosing blood cancers.
• To discuss both novel, high-throughput methods and cost-effective alternatives.
• To address practical considerations including preanalytics, data interpretation, and quality assurance.

Main Methods:

• Review of current and emerging molecular techniques in hematopathology.
• Inclusion of classical, low-cost, and workaround molecular testing strategies.
• Discussion of pre-analytical factors, data handling, bioinformatics, and performance evaluation.

Main Results:

• A broad spectrum of molecular diagnostic approaches for lymphoid and myeloid neoplasms is presented.
• Emphasis on adaptable strategies to overcome resource limitations in molecular testing.
• Key considerations for reliable and reproducible molecular diagnostics are highlighted.

Conclusions:

• Molecular techniques are indispensable for modern hematopathological diagnosis.
• A balanced approach incorporating advanced and accessible methods is necessary.
• Standardization of preanalytics, data management, and quality control is essential for interlaboratory precision.
