#mmsm Hematologica published 3 articles for sub-group analysis for Isatuximab recently:
1-IKEMA pts with renal failure-Full article 2- ICARIA-MM elderly pt-letter to editor
3-IKEMA+ICARIA-MM: 1q-letter to editor
🛑All used 1-2 medical writers
Was this all the story ? 🧵
Same medical writers helped in a review of key subgroup analysis of ICARIA-MM 👇
Also in doing another subgroup analysis in high risk cytogenetics
You think we are done: NO
ICARIA-MM subgroup analysis 👇
Expert review article with the help of medical writer 👇
Wait there is more , all good journals ICARIA-MM in renal impairment (some recurrent theme)
More and more 👇
ICARIA-MM sub group in East Asian
A letter with sub group analysis
Now more IKEMA subgroup analysis publications 👇in elderly
According to lines of therapy
Asian pts
Now you may ask yourself we the #MedOnc#MedTwiter#mmsm community should care?
🛑Too many subgroup analysis for one or combined studies being published too many times (and presented in conferences even more and repeatedly), I would argue this is a form of drug advertisement
We all want to see the results of trials , even the ones that do have some issues in design, etc. it is too much work by everybody etc, but this number of subgroup analysis for a single drug is not helping me to care for our patients and is bad inflation in publications
Actually this is harmful in other ways:
Look at the journals this was accepted in
Many are of good/excellent quality
Independent investigators submit to many of those journals
What happens?
Desk rejection (a lot of time,no reason)
Many don’t have $ to publish
In academia/clinical research , previously , the article get published fully with all the info and subgroup analysis , we are done. It may get updated once or twice in life time.
Nowadays, we will have updated sub-group analysis for endless things for the same study published and presented too many times reducing chances of others with no good addition to what we already know
Again, I believe we should do better in academia. I will be publishing on this aspects if editors allow my work to be reviewed and reviewers review it without getting it personal
I mean no persons, it is a culture
If we don’t change now, things will get only worse
Sorry long 🧵

#ASH21 Oral abstract:Ciltacabtagene Autoleucel for Triple-Class Exposed MM:Adjusted Comparisons of CARTITUDE-1 Patient Outcomes Versus Therapies from Real-World Clinical Practice from the LocoMMotion Prospective Study #mmsm 🧵
➡️ash.confex.com/ash/2021/webpr…
🛑some important issues👇
#ASH21#mmsm
➡️Cilta Cel is effective in difficult to ttt pts, this is not the aim of the discussion
➡️In this abstract,authors compared a prospectively matched triple class ref MM pts who received diff ttt vs Cilta cel
➡️ what did they find? 👇 (Cilta Cel better) but wait🛑
➡️Read results 👇
1️⃣countries:only 9% RWCP in US vs. 100% of pts who got Cilta Cel in CARTITUDE-1 were in US (16 Center) ➡️study compared pts across the ocean with diff access to ttt🙈
2️⃣>90 ttt options😅
3️⃣2 of the most frequently used regimens were doublet 🙈Kd (~14%),Pd (11%)
➡️ VOD (~15% ,all types): a bad complication with high mortality (severe type, historically >80%)
➡️ Diagnosis &grading(see tables👇) (nature.com/articles/bmt20…)
➡️Authors question: is defibrotide cost-effective using price input from Spain (note this is likely different from US)
➡️ Simplified definitions:
1⃣ Cost-effectiveness analysis(CEA) is usually measured by incremental cost-effectiveness ratio (ICER) and it establishes how much extra has to be paid for extra benefit.
Summary of cytoplasm/nucleus changes in leukocytes:
1️⃣ Hyposegmentation of neutrophils(peanut shaped, bilobed,or non-segmented nucleus with coarse chromatin)
🔬associations: Pelger–Huët anomaly(inherited) or pseudo-Pelger–Huët anomaly(acquired)
➡️Pelger–Huët anomaly(inherited):affect majority of granulocytes: autosomal dominant- mutations in the lamin B receptor gene
➡️Pseudo-Pelger–Huët anomaly(acquired): <50% of granulocytes: usually occurs with other morphological changes of malignancy: can see in MPNs or MDS #Heme
2️⃣Hypersegmentation of neutrophils
➡️≥ 6 lobes in granulocyte nucleus
🔬associations: megaloblastic anemia, chronic infections, MDS, familial(rare) #Heme
