MRD in Early-Stage NSCLC: Breakthrough or Not Yet? 🧬🔬

The conversation around Minimal Residual Disease (MRD) is heating up here at MTTB 2026. As we look at the evolution of ctDNA—from its first detection in 1948 to the clinical validations of today—the big question remains: Is it ready for prime time?

Key Insights from the session:
- Outcome Correlation: MRD positivity is consistently linked to worse clinical outcomes.
- Survival Indicators: Conversely, ctDNA clearance is showing a strong link to improved survival rates.
- The "Actionability" Gap: While the data is powerful, MRD status is not yet considered actionable for making definitive treatment decisions in standard practice.

We are standing on the edge of a major shift in how we monitor lung cancer, but we’re not quite there yet.

💬 Engagement Prompt: If a patient is MRD positive after surgery, would you feel comfortable changing their treatment plan based on that data today? Let’s hear your clinical perspective below.

Are we optimizing the right strategy in Advanced NSCLC? 🩺🤔

The landscape of first-line immunotherapy is evolving rapidly. Today at the Multidisciplinary Thoracic Tumor Board Conference, we tackled the critical nuances of IO strategy in advanced-stage disease.

Key Insights from the session:
- PD-L1 remains a critical biomarker guiding therapy
- Chemo-immunotherapy demonstrates durable survival benefit
- IO-IO combinations may benefit high-risk patients

A huge thank you to our moderators for leading this high-level discussion:
👤 Anne Chiang, MD, PhD
👤 Robert Millett IV, MD

💬 Discussion Points:
- Optimal sequencing and duration of therapy
- Personalization using biomarkers and co-mutations
- Management of resistance

Merry Christmas from your on-call hem/onc fellow at Mass General Hospital!

Thinking of everyone in the hospital today. It can be a tough day to be here, as an employee but even more so as a patient. Hoping the day can be as merry as reasonably possible.

[Percy Lee MD @PercyLeeMD]

Grateful this Christmas for the incredible @CityofHopeOC Radiation Oncology team. Each of you is a leader making a difference every day. With our new hospital open, we’re caring for patients without pause—because cancer doesn’t take a holiday.

Wishing peace and hope this X-mas!

Since the CHALLENGE data was reported at @ASCO & published in the @NEJM, there has been tons of discussion around the role of #exercise in #cancer. Check out my @cityofhope podcast w #LeeJonesPhD, an exercise physiologist who actually trained with the CHALLENGE authors before going to @MSKCancerCenter & now COH. Brilliant perspective on how to do exercise studies in patients with #cancer, assessing multiple “dose levels” much like we do in P1 trials. @Neil_Iyengar @PauloBergerot @ArmenianSaro @monda_steven @SWOG @DrVaishampayan @KidneyCancerDoc @KidneyCancer
