The presence of carcinoid syndrome (CS) in patients with sbNETs and liver mets undergoing debulking predicts worse survival and is, not surprisingly, associated w/ larger mets. Despite short PFS, OS is still long. Pts w/o CS can develop it over time https://t.co/wdyA2DU4YZ

I know that AI tools for ambient clinical documentation and note-writing shave off time creating notes and completing encounters. I wonder if that gain is lost when trying to decipher said notes later. I miss succinct summaries that show that thought was put into the plan...

Something for the IHC nerd in me... TRPS1 is an excellent IHC marker for identification of primary breast NETs as almost all tested cases were positive and all lung and pancreatic NETs were negative. https://t.co/w10WYZdI6B

TRPS1 is universally expressed in mammary NETs, and it is a valuable marker for distinguishing primary mammary NETs from metastatic NETs of other organs, such as the lung, gastrointestinal tract and...

More on PPIs and gastric NETs. Interesting work from the excellent Moffitt NET Team lead by the incomparable @altoubaht. The next steps should be to try to estimate the risk of NETs in long-term users. https://t.co/11c07OykvW

Charging the batteries before the beginning of next work week… No better way to do that than ride the gravel roads of SE Minnesota…😀 It is a privilege to live within 5 min ride from gravel roads.

Sharing some key Neuroendocrine presentations I’ll be looking for at #ESMO25 (virtually). So excited to see the field moving forward so quickly and kudos to ESMO for making sure rare/uncommon cancers get the spotlight they deserve. 🦓 💯 👏

First-line atezo/bev vs. durva/treme in pts w/ advanced HCC. 452 pt retrospective study showing no OS difference, 14 mos vs. 14.6 mos. My apologies for the poor quality OS graph. https://t.co/potNGPTmCK

Type IV gastric NET, the one associated with PPIs... More data pointing to a subset of gastric NETs associated with long-term PPI use, often called type IV. Compared to type III, type IV is much more indolent and less likely to metastasize. https://t.co/uy7NrQw49t

This sentence is from a just-published paper on the efficacy of liposomal irinotecan in biliary tract cancer (BTC) in a very respectable journal. In the words of my program director, Tim Moynihan 20 years ago "Patients do not fail therapy. The therapy fails the patient"

The difference quality imaging makes in the assessment of localized small ileal NETs... CT enterography... Patient who had ileal resection for multifocal G1 NETs 7 years ago (remember >50% are multifocal). Postoperative imaging showed residual multifocal NETs. On observation.

Are you like I, struggling with sequencing systemic therapies in G2/G3 GEPNETs and wondering where PRRT fits in that picture...? If so, you might find this paper helpful. Sure, we need better data but here is what we know. @AmanChauhanMD @NVijayvergiaMD https://t.co/e5ZXgRGlpy

Morning commute on overgrown single track listening to Jesse Welles (who I just discovered this weekend). If you don’t know Welles, you should check him out. A little Dylanesque music. Fantastic songwriting and lyrics, taking on some of the current issues.
