We are on a roll. We have opened our 12th site. Welcome to NHS Lothian - Western General Hospital, Edinburgh.
You are going to smash recruitment. Good luck.

Which is exactly why we at @IBCG_BladderCA [and @sitcancer] have maintained that TaHG should be classified as high risk.
Because the clinical outcomes, molecular biology, progression patterns, all point in the same direction.
High-grade biology matters more than arbitrary cutoffs; a TaHG tumor does not suddenly become biologically “intermediate risk” because it is 2.95 cm versus 3.02 cm
Classification is not semantics. Classification drives treatment. And treatment drives outcomes. @BladderCancerUS @WorldBladderCan

Great discussions here at the Masterclass on Muscle-invasive bladder cancer, April 16 & 17 in Amsterdam, the Netherlands.
It was a pleasure to reconnect with Prof. Prof Param Mariappan during the congress. #innovation #oncology #BladderEpiCheck

What could have been a turf war turned into something far more valuable! Our patients with #BladderCancer deserve better than siloed care after TMT. Shared surveillance and multidisciplinary counseling are the standard we should be holding ourselves to right now.
I know some of you were hoping for more fireworks at #EAU25 - May 17 might be your lucky day. 😏 @IBCG_BladderCA - @AmerUrological #BladderCancer Forum at #AUA26

Managing radiation toxicity after trimodal therapy for #BladderCancer. @UroDocAsh @UTMDAnderson moderates a debate between Antoine Van Der Heijden, MD, PhD @radboudumc & @NehaVapiwala @PennMedicine. Urologists vs Radiation Oncologists, both advocate for multidisciplinary counseling and shared surveillance rather than siloed specialty management. #WatchNow > bit.ly/4tHQy5y

After all the comments on EV209 (A phase 2 study of EVPx9 without cystectomy in the cCRs in MIBC patients), we decided to make a @Uromigos podcast on it and invite some of the voices @LauraBukavinaMD @AmandaNizamMD @DrTylerStewart ⚡️🌪️👉podcasts.apple.com/us/podcas…
Mar 21
A 240 pateint single arm trial exploring 9 cycles of EVP without planned surgery in MIBC. This will answer the key questions ‘What happens if we don’t do cystectomy in those with clinical complete response after initial EVP’.It assesses cCR rates and bladder intact EFS. It will clarify ‘EVP 1st ask questions later’ #GUtrendingTopics @OncoAlert

The most important step at the beginning of almost every #BladderCancer patient's pathway.
Regardless of technique, it is vital to deliver the #TURBT as a package.

Couldn’t agree more!
This is why the @IBCG_BladderCA will make this one of the focus topics of our retreat this year, #IBCG26

As we wrap a whirlwind of data in bladder cancer at #GU26, wishing everyone safe travels home. Rest up - London and #EAU26 are just around the corner!
I'm especially excited to once again lead the "Common Problems and Controversies in Bladder Cancer: Rapid-fire Debates." Friday 13 March 10:45 - 12:15
We’ve designed this session to cut through the noise - no long lectures - just leading experts, opposing viewpoints, and the direct clinical insights you need for daily practice. It remains one of the most anticipated highlights of the meeting for a reason!

Efficacy means nothing if we can't get our patients to finish the course!🏁✅
Looking forward to discussing strategies to reduce toxicity, improve patient adherence, decrease dropout rates, and improve efficacy of intravesical BCG 💫

Very important study. Most NMIBCrelated costs are driven by overtreatment and oversurveillance in LR disease. Kudos to @ParamMariappan for this key step toward deintensifying FU in LR NMIBC. Together with treatment deintensification, it can rationalize costs and improve pts QoL
20 years ago we suggested ceasing surveillance in G1Ta #BladderCancer after 5 recurrence-free years: pubmed.ncbi.nlm.nih.gov/1575…
From our recent work, further de-intensifiction of surveillance in low risk patients is feasible. authors.elsevier.com/a/1mHug…

Assessing baseline bladder function for patients considering trimodal therapy. Comron Hassanzadeh, MD, MPH joins @UroDocAsh to discuss emerging comprehensive bladder toxicity measurement tools. The discussion covers technical advances, including IMRT optimization to reduce gastrointestinal and genitourinary side effects, while addressing bladder motion management during treatment. #WatchNow > bit.ly/3KEPcri @MDAndersonNews @IBCG_BladderCA
