Practice-changing in colon cancer?
Adjuvant immunotherapy + chemo cuts recurrence risk by 50% in stage III dMMR colon cancer.
ATOMIC trial delivers.
๐ฅ Study population
Resected stage III dMMR/MSI-H colon cancer
โ ๏ธ ~54% high-risk (T4/N2)
โ๏ธ Arms
๐ฆ Atezolizumab + mFOLFOX6 โ atezo maintenance (1 year total)
โฌ mFOLFOX6 alone (6 months)
๐ Key results
โข3-year DFS: 86.3% vs 76.2%
โขHR: 0.50 (P<0.001)
๐ ~10% absolute gain
โ ๏ธ Toxicity trade-off
โขGrade 3-4 AEs: 84% vs 72%
โขMore immune AEs (thyroid, colitis, hyperglycemia)
โ OS immature
๐ฏ Clinical takeaway
For stage III dMMR colon cancer,
๐ IO + FOLFOX is likely the new adjuvant standard
๐ฌ Test MMR in ALL colon cancers. This now directly impacts adjuvant therapy.

Just in: Good news for the myeloma field.
FDA approves teclistamab plus daratumumab (Tec-Dara) combination for myeloma for patients who have had at least one prior line of therapy.
Note: Always use Tec-Dara with monthly IVIG. Itโs not optional.
That was fast! And this is unprecedented curve is why.
This changes how we approach first relapse.
In Dara sensitive patients: Tec-Dara or Cilta-cel are the top two choices.
If Dara refractory: Bispecifics alone or Cilta-cel are the main options.
CART and Bispecifics both need close monitoring and specialized care and certain requirements. So for some patients, we may still use triplets.
โข Pegfilgrastim timing matters
โข 24h โ higher early WBC spike
โข 72h โ โ bone pain
โข 72h โ more controlled WBC curve
โข No loss of efficacy
Maybe 72 hours is the sweet spot ๐

Amazing to be a leukemia MD in this day & age. This is the timeline of new๐approvals in AML that I get to show our @MCG_AUG Heme/Onc fellows. The last decade has sure been exciting. What's next? #leusm#MedEd
๐ #ASCOGU26 is almost here! What might the data show?
โข Practice-changing perioperative IO?
โข ctDNA precision?
๐ค Note: These are only AI predictions.
๐ Watch out for the final readouts!

The Paclitaxel + Carboplatin "CarboTaxol" doublet is the bread and butter of oncology for a reason. ๐๐ง
But why does this specific combo work so well?
Itโs all about the "Freeze and Snap" synergy. โ๏ธ๐ฅ
1๏ธโฃ The Freezer (Paclitaxel):
Paclitaxel stabilizes microtubules, preventing depolymerization.
It freezes the cellโs skeleton in the M-phase (Mitosis). The cell tries to divide but gets stuck. ๐ย
2๏ธโฃ The Snap (Carboplatin):
While the cell is arrested and stressed, Carboplatin slides in.
It acts as an alkylating agent, forming reactive platinum complexes that bind to DNA (cross-linking). ๐งฌ๐ย
๐ค The Synergy (Why 1+1 = 3):
The magic lies in the timing.
Paclitaxel arrests cells in the G2/M phase.
Cells in this phase are less efficient at repairing the DNA damage caused by Carboplatin.
The "Freeze" prevents the "Repair," leading to accumulation of DNA damage โก๏ธ Apoptosis (Cell Death). โ ๏ธย
๐ก Clinical Pearl (The Sequence Matters):
This is why we often administer Taxane before Platinum.
Giving Paclitaxel first avoids the antagonistic effect where Carboplatin might inhibit the uptake or cytotoxicity of the taxane.
It also reduces thrombocytopenia! ๐๐ฉธ
