Please see, and I hope enjoy, my new JCO OP editorial on where we sit with metastatic cancer.

Every ASCO has some hidden pearls. One that I had the luck to attend was a presentation by Gil Shamai on the discordance between AI prediction and standard path features — wonderfully discussed by David Rimm. Highly recommended.

Possible mechanisms of resistance to T-DXd in breast cancer patients using real-world data and multiomic profiling
⬆️ABCC1 and ⬇️ERBB2 showed ⬇️OS, in line with previous works on T-DXd.

A Real-World Experience in Pan-Tumor Testing for HER2 IHC in More Than 65 000 Solid Tumors
jamanetwork.com/journals/jam…
Trastuzumab deruxtecan-nxki (T-DXd) received tumor-agnostic FDA approval in April 2024 for adults with unresectable or metastatic HER2-positive (IHC 3+) solid tumors lacking other treatment options, based on responses seen across three DESTINY trials. This prompted widespread HER2 IHC testing across tumor types, leading to the first large-scale report on real-world HER2 IHC 3+ prevalence using standardized interpretation criteria. Among over 65,000 tested patients, HER2 IHC 3+ rates varied widely by cancer type, with #BladderCancer showing the highest prevalence (13.9%), while others—like gliomas, sarcomas, #ProstateCancer, and kidney cancers—had minimal or no expression.
These findings suggest universal HER2 testing may not be necessary for all solid tumors, and a more targeted approach—initiating HER2 IHC only after identifying ERBB2 amplification or overexpression via comprehensive genomic profiling—could reduce unnecessary testing while optimizing workflow and cost-efficiency.

Caris has published a 295,000+ patient study revealing variable efficacy among cancers for patients treated with tissue-agnostic drugs and uncovering the potential for expanding approvals to other drugs in the same class. Learn more: ow.ly/Ii5x50VlbqJ

In addition to our paper ja.ma/47EB7zR, I’d also like to point you to the editorial jamanetwork.com/journals/jam… and @kristac's piece on it med.stanford.edu/news/all-ne….
Also for TROPION 01, obviously need OS. For field as a whole we could use structured crossover trials from ADC1–>ADC2. And we need a better understanding of resistance: resistance based on target vs payload.
TROPION Breast01 updated from October ESMO shows 2.4 mo improvement in PFS vs ineffective late line CT with improved QOL vs CT. Question: should we require, going forward, comparisons vs other ADCs rather than vs essentially inactive CT?
Monarch 3 frontline OS results for Abema continue to show numerically impressive improvements but a significant p value remains frustratingly elusive. This is confusing given positive second line and adjuvant results.
With both neoadjuvant Nivo and Pembro in ER pos BC pCR rates increase strongly as PD-L1 increases. Two questions: should we use PD-L1 as a predictive biomarker, and should we use either of these drugs in the absence of solid EFS improvements?
