David Gandara: “not so fast”

David Gandara, Director of Thoracic Oncology and Senior Advisor to the Director at University of California Davis Comprehensive Cancer Center (UCDCCC), shared a post by Vivek Subbiah on X/Twitter adding:

Congratulations Vivek Subbiah on addressing unmet need to standardize criteria for liquid biopsy response. But as the saying goes, “not so fast”! Considering wide variability in assay methods and computational algorithms, first need to harmonize assays themselves.”

Quoting Vivek Subbiah’s post:

“Liquid Biopsy Response Evaluation Criteria in Solid Tumors (LB-RECIST) – Annals of Oncology.
Thank you. Yes ! This is just the beginning of the conversation on using LB for response. We outline several issues that need to be addressed before recommending the implementation of ctDNA response criteria in daily clinical practice such as clinical, biological, and regulatory challenges and, most importantly, the need to standardize/harmonize detection methods and ways to define ctDNA response and/or progression for precision oncology.”
