FAQ
Who are the top GU Cancer KOLs in the USA in 2026?
In the KOL Pulse 2026 GU Cancer rankings, the top US physicians are Toni Choueiri, MD (#1), Neeraj Agarwal, MD, FASCO (#2) and Oncology Brothers (#3). The full US top 20 is listed on this page and updated after each major meeting.
Who are the top GU Cancer KOLs worldwide in 2026?
Globally, the top GU Cancer physicians on X in 2026 are Tom Powles (#1), Toni Choueiri, MD (#2) and Neeraj Agarwal, MD, FASCO (#3). The Global tab lists the top 20.
How are the KOL Pulse GU Cancer rankings determined?
The rankings measure verified physician engagement with each oncologist's posts about gu cancer clinical trials on X: reposts, quotes, replies and mentions from other physicians. Engagement around the major oncology meetings (ASCO, ESMO and ASCO GU) counts most. Only physicians are ranked, and only engagement from physicians counts.
What is the Peer Engagement Score?
It is a relative score out of 100. The top-ranked gu cancer physician worldwide scores 100, and every other physician is scored against that leader. The same score appears on the US and Global lists, so the two are directly comparable.
Who is eligible for the rankings?
Practicing physicians whose trial posts are engaged by several different physician colleagues. Media, industry and institutional accounts are not ranked, and engagement from them does not count.
How often are the rankings updated?
KOL Pulse updates the GU Cancer rankings after each major meeting. This page was last updated November 10, 2026.
Can I see more about each GU Cancer KOL?
Yes. Each ranked US physician links to a KOL Pulse profile with the clinical trials they discussed, their 2025–26 presentations, the colleagues who amplify them and their CMS Open Payments summary.
