Preanalytical protocol for fresh solid tumor biospecimens

TL;DR

This paper presents a protocol to reduce errors in lab tests by standardizing the handling of fresh solid tumor tissue from collection to testing.

Contribution

The paper introduces a comprehensive preanalytical protocol for handling live solid tumor biospecimens, which is currently lacking in the field.

Findings

Most diagnostic errors stem from preanalytical variability in tissue processing.

Standardized protocols for fresh solid tumor tissue can improve biospecimen integrity and diagnostics.

The proposed protocol covers collection, handling, and logistics to preserve tissue viability.

Abstract

Nearly seventy percent of diagnostic lab test errors occur due to variability in preanalytical factors.

These are the parameters involved with all aspects of tissue processing, starting from the time tissue is collected from the patient in the operating room, until it is received and tested in the laboratory. While there are several protocols for transporting fixed tissue, organs, and liquid biopsies, such protocols are lacking for transport and handling of live solid tumor tissue specimens. There is a critical need to establish preanalytical protocols to reduce variability in biospecimen integrity and improve diagnostics for personalized medicine.

Here, we provide a comprehensive protocol for the standard collection, handling, packaging, cold-chain logistics, and receipt of solid tumor tissue biospecimens to preserve tissue viability.
