    Area of Science:

    • Oncology
    • Pathology
    • Biotechnology

    Background:

    • Preanalytical variability accounts for nearly 70% of diagnostic laboratory errors.
    • Existing protocols inadequately address the transport and handling of live solid tumor tissue specimens.
    • Standardized preanalytical protocols are crucial for biospecimen integrity and personalized medicine.

    Approach:

    • A comprehensive protocol is presented for the collection, handling, packaging, and transport of live solid tumor tissue.
    • The protocol emphasizes cold-chain logistics to maintain tissue viability from collection to laboratory receipt.
    • This standardized approach aims to minimize preanalytical variability in solid tumor biospecimens.

    Key Points:

    • Live solid tumor tissue requires specific handling protocols distinct from fixed tissues or liquid biopsies.
    • Maintaining tissue viability during transport is critical for accurate downstream diagnostic testing.
    • The proposed protocol addresses the entire chain of custody for solid tumor biospecimens.

    Conclusions:

    • Implementing this standardized protocol will reduce preanalytical variability in solid tumor diagnostics.
    • Improved biospecimen integrity supports more reliable results for personalized medicine applications.
    • This work establishes essential preanalytical guidelines for live solid tumor tissue handling.
