The #NCI past meets the present #GU26 @ascocancer.bsky.social

Dr. Melissa Abel discusses emerging #PSMA tumor volume data with Dr. Harpreet Singh

The emerging data is from a follow-up trial based on a trial Dr. Singh worked on during her time at the NCi

3 1 0 0

More data on PSA
Almost none on PSMA

So I would not used PSMA “response” since all that really is telling us about fundamentally is #PSMA expression.

One key bit of data missing in the context of #PSMA+ #BCR #ProstateCancer management in the wake of the #EMBARK data is how does #PSA Doubling Time interface w/ #PSMA Pet findings.

Dr. Melissa Abel from #NCI will share this data today

“These findings… highlight the need for larger… studies to validate the prognostic value of PSMA-guided disease stratification & ensure its generalizability across diverse populations.”

Agree!! Need more #PSMA data less presumption in #ProstateCancer

New review highlights how PSMA‑targeted radioligand therapy, including 177Lu‑PSMA‑617 and emerging isotopes like 225Ac/161Tb, is reshaping advanced prostate cancer care. Combination strategies and precision dosimetry point to a rapidly evolving future.

New research from Dr. Samir Zaidi with Dr. Michael Morris @mskcancercenter.bsky.social shows #PSMA expression can vary in #mCRPC, even in tumors that appear PSMA+ on imaging. Combining PSMA scans with blood-based biomarkers may help inform treatment decision–making.

Daily reminder:

#PSMA doesn't show everything...

100 pts w/#BCR #ProstateCancer s/p previous PSMA radioguided surgery

▶️median PSA=0.9

‼️91% recur@ median 11.4mos
‼️47%w/ distant recurrence beyond pelvis

Important for pts to be aware of these data

Systemic Mastocytosis Can Mimic Metastatic Prostate Cancer: A Case Report This report is the first documented case of PSMA expression in systemic mastocytosis, highlighting a potential diagnostic dilemma for clinicians.

A patient with a prostate-specific membrane antigen (#PSMA)-positive PET/CT findings was ultimately diagnosed with #SystemicMastocytosis (SM) rather than metastatic #ProstateCancer, according to a recently published case report.

Not all PSMA+ BCR is oligo mets and PSMA+ BCR is very different than mCSPC. Imaging platform matters for patients and outcomes when defining “oligomets” but trials are very inconsistent on this key issue.

Lots of ❓s in defining benefits of “#oligomet” or “#MDT” therapy in #ProstateCancer

❓ADT+/-ARPI? How long?
❓PFS vs Eugonadal PFS?
❓how many mets? Where?

We don’t need to fear the Dark in #ProstateCancer

But we will have to acknowledge that #PSMA targeted therapy will likely impact the sensitivity of #PSMA imaging

This likely impacts the desire to use PSMA in restating (still unclear how to do that) & drug development #PSMAdark

Lots @ #ESMO25 re: #BCR #ProstateCancer but over-treatment of this indolent disease remains an important issue

How does #PSMA imaging factor in? See poster #2393P presented by @HelenMoonMD Saturday

+PSMA findings in BCR pts shouldn’t be the reason to treat as rPD is rare @1yr
