Great discussion and wonderful to see a former fellow with us, Akeem Lewis, discuss. I came here on a J-1 visa and got my H1B and ultimately Green Card working at the VA which was an excellent place to start the career and for me, was a fun place to work with the best patients.

PRRT is a very effective for well-differentiated NETs but associated with a low risk of treatment related myeloid neoplasms ( t-MN ). If you are interested in learning more, this is the review for you... 😀 Bassam Sonbol Mrinal Patnaik yael kusne MD PhD erc.bioscientifica.com/view/journals/…

What works for malignant insulinoma...? Actually, many things do. If you want to learn more, Dr. Regina Koch has the paper for you. In this 57 pt retrospective study, PRRT, CAPTEM and everolimus all had activity for hypoglycemia and OS can be quite long. erc.bioscientifica.com/view/journals/…

The next frontier in radioligand therapy (RLT), radioligand-antibody drug conjugates...? Interesting data targeting TROP2 and HER2 in xenograft mouse models with orthotopic breast tumors. I am certainly keeping an eye on how this develops... aacrjournals.org/mct/article/24…

Neoadj chemo (NAC) for resectable pancreatic adenocarcinoma. Small study, non-comparative RCT-II and as such does not answer the question of all should have NAC but at least it is feasible.Kudos to Journal of Clinical Oncology for automatically including appendix material! ascopubs.org/doi/pdf/10.120…

I still get excited about good clinical papers! 😀I have been waiting for this one with much anticipation... For anyone taking care of patients with MEN1 or interested in learning more, this is the document you need. Kudos to the team that got this done including Mark Lewis, MD, FASCO !

Excellent work and important addition to the literature of malignant insulinoma. The short summary is, PRRT works! Very similar results to what we recently reported... erc.bioscientifica.com/view/journals/…?
