Take🏠messages:
⬆️ options to tx HER2+ #MBC
✅T-DXd >T-DM1 in 2L setting (DESTINY BREAST-03)
✅Beware ADC tox- think 🫁pneumonitis & GI w T-Dxd
✅ADC design is 🗝:
➡️Need to consider DAR, linker, ability to cause ADCC
✅ADC + IO= open ❓
Take🏠messages (cont’d):
✅T-DXd active against brain mets (TUXEDO-1)
✅Triplet (tucatinib, cape, tras) also active in brain mets
✅Next up: T-DXd in HER2 LOW- trials ongoing
Take🏠messages: #CRC 🚫one disease!
✅Diff 🧬subtypes that define tx sensitivity
✅BRAFv600E is bad–but may be ⬆️sensitive to IO w MLH1 meth
✅Neoadj tx: 🦊FOXTROT= poss benefit, depends on subgroup
✅Keynote177: IO= way to go in dMMR!
We looked at dx and tx of Carcinoma of Unknown Primary (#CUP), including how 🧬 can change tx.
There was a lot to learn–we captured what we could of the discussion here:
2/9 #TumorBoardTuesday Thurs Case🎀
Take🏠: #CUP is complicated!
✅Comprehensive approach needed, including:
H&P,🔬, 🩻, 🧬
✅Overall inc of CUP is ⬇️–many liver CUP being recognized as cholangio
✅NGS can help augment the w/u
✅STK11= frequently mut in lung; ⬇️response to IO
