Two patients with refractory myeloma who had excellent antitumor responses to cilta-cel CAR T-cell therapy later had T-cell lymphomas that contained the lentivirus construct used to generate the CAR T-cell product. Brief Report on the CARTITUDE-4 trial: nej.md/4gA6G27

CAR+ T-Cell Lymphoma after Cilta-cel Therapy for Relapsed or Refractory Myeloma | NEJM
We describe two patients in whom malignant monoclonal T-cell lymphoproliferation developed after administration of chimeric antigen receptor (CAR) T-cell therapy with ciltacabtagene autoleucel (cil...

A recent case report from MSKCC published in the NEJM describes the development of a CD4+ T-cell lymphoma in a patient with multiple myeloma following B-cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T-cell therapy.

A woman with multiply relapsed multiple myeloma had complete remission with cilta-cel, but a low-grade T-cell lymphoma soon developed in the GI tract that contained an insertion of the CAR construct disrupting expression of p53. Read the Brief Report: nej.md/40Yq3gO

Attempt at putting what we know about #BTK resistance mutations into one figure..

Beware inducing cross-resistant L528Wmuts pre ncBTKi.

Make sure you are testing for UBTF-TDs in paed MDS/AML (and adult MDS/AML!).
Morphological/immunophenotypic clues = dysplasia in paed AML, CD34/CD117 dim
Molecular clues = FLT3mut/WT1mut
Menin inhibition as potential therapeutic modality.

What a joy it is to hear our very own Sant-Ryan Pasricha presenting Best of #ASH24. Who else could personalise this so much and use a picture of the hallowed ground of the @MCG (Melbourne Cricket Ground) to such good effect? Go Santa!

Therapy related myeloid neoplasm post CART in DLBCL arises from TP53 clones identifiable preCART… but high baseline incidence of TP53/PPM1D CH preCART.. so the challenge is identifying those with clones that will progress - Zhi Han Yeoh from @petermaccc.bsky.social. #ASH24 #hemepath #hemesky #lymsm

Very interesting R-CHOP+X session (or Pola-R-CHP+X..) in DLBCL. 3/6 presentations in the session with data presented on ctDNA MRD!.. including the COALITION study (Adrian Minson/ @drmikedickinson.bsky.social. CtDNA helpful in resolving nature of EOT PET abnormalities #ASH24 #lymsm #hemesky #hemepath

Critical RW data, especially data re: better PFS for pola for non-GC in the post-CAR setting. Huge congratulations to Drs. Cliff and Russler-Germain for this tour de force, and for inviting us at @CULymphoma @CUHematology (and @JessicaAllenMD) to participate. #ASH24 #lymsm

Dr. Jacoby from Washington University on intervening in AML based on mut clearance at 2.5% VAF across exome level in a variant agnostic way. Great to see this “fingerprint” MRD approach being used in trials.. lots of analogies to current lymphoma ctDNA space #hemepath #hemesky #leusm #lymsm #ASH24

Exciting to see the first results from the INTERCEPT platform study (PI Andrew Wei) expertly presented by Dr. Sun Loo from @petermaccc.bsky.social at #ASH24. Intervening with a molecularly rational approach at early #MRD relapse is feasible in AML and the results with revumenib are encouraging.

Dr. Ing Soo Tiong from @petermaccc.bsky.social presenting his excellent work at #ASH24 on how the remission clonal haematopoietic landscape is shaped by venetoclax in pts with AML. TP53 and BAX microclones! With a bit more sensitive sequencing tech we will find the nanoclones… #hemepath #hemesky

A great (in-person!) meeting of the MM-VCEP #ClinGen group today at #ASH24. Lots of exciting projects and milestones for the group on the horizon including making rules for new genes (SAMD9/SAMD9L/TERT/TERC..) as well as progress on our DDX41 curation rules. Stay tuned..

- 43% had CH prior to CAR: 54% DNMT3A, 26% TP53
- 6% developed MN: 3-yr cumulative incidence of 11% with death from LBCL as competing risk
- median time CAR to MN 25 mos

We recently joined forces with the University of Melbourne to create the Collaborative Centre for Genomic Cancer Medicine.

It's Director Prof Sean Grimmond and A/Prof David Westerman joined ABC Melbourne to talk about the new centre's mission and future of #genomicmedicine.

A fascinating listen!
Why are scientists so excited about genomics? - ABC listen
Genomics explores the building blocks of human DNA, in the hopes of uncovering patterns that can lead to lifesaving medical discoveries.
