Molecular Testing in Solid Tumors: Best Practices from the Molecular Pathology and Precision Medicine Study Group of the Italian Society of Pathology (PMMP/SIAPeC)

The Italian Society of Pathology's Molecular Pathology and Precision Medicine Study Group (PMMP/SIAPeC) has released a three-part set of best practice guidelines to stan-dardize and enhance molecular testing in solid tumors. Part I focuses on the pre-analytical phase, emphasizing proper tissue handling and quality control to preserve nucleic acid integrity. Part II addresses the analytical phase, outlining workflows for next-generation sequencing (NGS), from extraction to variant interpretation, with recommendations on choice of platform, gene panels, and bioinformatics. Part III covers the post-analytical phase, offering guidance on structured, clinically meaningful reporting to support thera-peutic decisions, including standards for both tissue and liquid biopsies. Together, these documents aim to harmonize molecular diagnostics, ensuring reliable, high-quality results that support precision oncology.
