If it’s nighttime where you are, and you’re relatively more north, I recommend going outside and looking up right now. Thanks, Nature! #Auroraborealis

Fantastic effort in collaboration with my colleagues Katrina Pedersen, MD, MS Yin Cao WillChapmanJr MichaelIglesia Siteman Cancer Center. Abdominal pain is the most common symptom. GI bleeding most strongly associated with diagnosis. Check your 💩. Get your screening colonoscopy.

We are electric! Always awesome yet far too rare for mOS benefit in Ph3 PDAC trial, but PANOVA-3 mOS 16.2m for TTF+GnP vs 14.2m GnP?🤔 Look forward to seeing full data and actual pt experience with device to determine clin significance. biospace.com/press-releases…

We prefer fair and balanced clocks. Daylight Saving Time is a mandate to wake early and sleep less. Permanent Standard Time keeps the sun’s zenith at noon—best for health and safety!

BREAKWATER shows that 1L EC+FOLFOX results in mPFS 12.8m and mOS 30.3m!! 🥹🥲 That mOS far exceeded my greatest hope for this study. A great turning point for a bad actor 🙌👊🏻 #ASCO25

CRC staging: AJCC v9 Era Past: “TNM.” Now: “TNDM” staging system, incorporating tumor deposits as independent entity. I like it. Better than N1c grouping-better reflects survival risk. Will be a learning curve though… AJCC v10 prediction: TNDM+ctDNA 🤔
