Talking Points

Recent interactions between the hosts and their guests.

The Precision Shift: Re-Writing the Colorectal Cancer Roadmap with Dr. Arvind Dasari
Q: What are the practical challenges of implementing CTDNA testing in real-world settings?
Turnaround times for tissue NGS are longer; integrating rapid liquid biopsy can get results before infusion, but there are regulatory and IDE considerations that can complicate standard-of-care testing on trial.
The Precision Shift: Re-Writing the Colorectal Cancer Roadmap with Dr. Arvind Dasari
Q: How does Circulate use CTDNA to decide on de-escalation or escalation of therapy?
CTDNA positive patients may be randomized to standard care or escalated therapy, while CTDNA negative patients can be de-escalated from standard regimens or observed, creating a risk-adapted approach based on tumor DNA status.
The Precision Shift: Re-Writing the Colorectal Cancer Roadmap with Dr. Arvind Dasari
Q: Starting with biomarker testing, who should be tested and what should be included?
Ideally every patient should receive broad molecular testing (MSI/MMR, BRAFV600E, HER2, NGS panels) at first encounter, with liquid biopsy as a rapid interim tool to guide urgent decisions while tissue results are pending.
