After 15 years of training, excited to be starting as a Genitourinary Oncologist and Instructor @MSKCancerCenter! Very thankful to my wife & daughter who have put up with me during my training, the fellowship program, and all my incredible mentors along the way! @MSK_DeptOfMed

Results of the T-DXd/durva arm of #BEGONIA for 1L mTNBC are now out in @NatureCancer. High efficacy, with ORR 62% and mPFS 12.6 months. Strikingly, deep responses observed even in HER2-0 (null) dz, reminding that IHC is a poorly predictive ADC biomarker. nature.com/articles/s43018-0…

⚠️ New findings presented in the plenary session at #ASCO26 suggest daraxonrasib could help usher in a new era of treatment for metastatic pancreatic cancer. In a phase 3 study led by @EileenMOReilly and colleagues, patients receiving #daraxonrasib lived a median of 13.2 months compared with 6.7 months for those treated with chemotherapy. "To date in my career, I have not seen this level of benefit from any single anti-cancer drug in this disease." Learn more: bit.ly/435pwKo

Presented at #ASCO26: Among patients with previously treated metastatic pancreatic ductal adenocarcinoma, the RAS(ON) inhibitor daraxonrasib led to significantly longer overall survival and progression-free survival than chemotherapy. Full phase 3 RASolute 302 trial results: nej.md/4nWaxvM @ASCO

Clear cell RCC sheds low levels of ctDNA, but positivity and ctDNA dynamics are relevant in the adjuvant setting @DrChoueiri #ASCO26. This analysis is with an exome based personalised technique and shows a lack of sensitivity (5-8% ctDNA ve rate vs 40% radiological relapse rate) but good specificity (almost all ctDNA ves relapse). Whole genome ctDNA analysis should work work better. There is a future for ctDNA in renal cancer, we’re just not quite there yet IMO.

PICI has named Rebecca Sager, urologic oncology fellow at @MSKCancerCenter, the inaugural recipient of the Conquer Cancer - Parker Institute for Cancer Immunotherapy Endowed Young Investigator Award. Dr. Sager is being recognized for her important research exploring tumor immunology and how treatments shape the tumor immune microenvironment in clear cell renal cell carcinoma (ccRCC). Her work represents the kind of innovative science that continues to advance the future of cancer immunotherapy and improve outcomes. Congratulations to Dr. Sager on this well-deserved recognition! parkerici.org/the-latest/dr-…

Just one day after ending "The Late Show" on CBS, Stephen Colbert returned to TV — to host a public access show with rocker Jack White in Monroe, Michigan. Appearances by Jeff Daniels, Eminem and Steve Buscemi.

Retatrutide, a triple receptor drug for GLP-1, GIP, and glucagon, is the most powerful weight loss drug yet. A significant issue is too much weight loss among the trial participants. New randomized trial results announced today with 28% body weight loss. gift link nytimes.com/2026/05/21/scien…

Timely analysis from the trial that led to the approval of the first tumor-agnostic HER2-directed therapy in patients with HER2 IHC 3 advanced solid tumors, including advanced urothelial carcinoma. Discordance between local & central HER2 IHC scoring highlights the need for a standardized scoring system not only to identify patients eligible for Enhertu, but also those with HER2 IHC 1 /2 /3 expression who may be eligible for the growing number of HER2-directed clinical trials. aacrjournals.org/clincancerr… @OncoAlert @jamecancerdoc @koshkin85 @OncBrothers @DrKarineTawagi @CanDAydogdu @LauraBukavinaMD @emanuele_crupi @DanieleRaggi83 @niklas_kluemper @PTarantinoMD @Uromigos
Are #HER2-targeted #ADCs moving faster in #urothelial cancer than our ability to define who is truly HER2-positive? No current HER2 scoring framework was designed for urothelial tumour biology. Now out on @NatRevUrol @DanieleRaggi83 @Pederfizzo doi.org/10.1038/s41585-026-0…
