A verified, classified map of the #ESMO26 gastrointestinal cancer conversation across 27 gastrointestinal cancer trials: 864 accounts from curated posts, including 431 physicians — 135 US physicians and 296 international colleagues, from 49 physician countries including the US (Spain, India, Turkey, Brazil lead outside the US). Institutional clusters are visible in the conference conversation: Memorial Sloan Kettering Cancer Center (6), Dana-Farber Cancer Institute (6), Mayo Clinic (4), Cleveland Clinic (4). Trial interest concentrates around CLARITY-Gastric01 (118 physicians), MASTERPLAN (118 physicians), HARMONi-GI1 (114 physicians). 35 patient advocates and advocacy organizations are active in the same conversation — and the bot and persona accounts that inflate raw follower metrics were identified and quarantined, so every physician here is bio-verified.
Benchmark your own #ESMO26 gastrointestinal cancer presence against the 431 physicians mapped here: are your trials of interest among the crowded conversations (CLARITY-Gastric01, MASTERPLAN, HARMONi-GI1) or the quiet ones where a single voice still stands out? The category and region breakdowns show which patient advocacy voices and international colleagues were active in your space, and the trial section names the physicians - with their institutions - engaged with each trial.
An MSL following up after ESMO 2026: Memorial Sloan Kettering Cancer Center alone had 6 physicians in the #ESMO26 gastrointestinal cancer conversation. Cross-reference the trial section — CLARITY-Gastric01 (118 physicians), MASTERPLAN (118 physicians), HARMONi-GI1 (114 physicians) are the crowded conversations — and the follow-up plan writes itself: which physicians at which institutions engaged with which trials during the meeting, before a single follow-up is booked. A KOL can run the same play in reverse: find your institution's cluster, see which trials your colleagues converged on, and position your own commentary where the map shows white space.
As post-meeting follow-up planning grounded in this page's own numbers: the category and region breakdowns surface the 135 verified US physicians and their international colleagues, each with institution and trial interests; the classification keeps engagement lists clean by separating treating physicians from the 67 media accounts and industry voices; and the trial-interest chips let field teams match MSL briefings to the trials a physician already follows. KOL identification tells you who matters; mapping tells you how the community organizes around institutions and trials — which is what engagement sequencing actually needs. Influence-mapping practice guides note this also reduces redundant outreach: teams see who is already saturated and who is unengaged.
Oncology standards change with each congress readout, and physicians increasingly learn about readouts from each other online — surveys report over 70% of HCPs use digital channels weekly for medical information, and in a LiveWorld–Sermo survey of 206 US physicians, 41% said social media influences prescribing behavior. A conference map matters because meeting days are when oncology opinion forms: this dataset shows the communities that organized around the ESMO 2026 GI readouts — Memorial Sloan Kettering Cancer Center and Dana-Farber Cancer Institute clusters, 35 active patient advocacy organizations, and CLARITY-Gastric01-focused physician groups.
A traditional KOL earns influence through trials, publications, and guideline work; a Digital Opinion Leader earns it through digital reach — posts, threads, podcasts, and amplification. Many physicians on this page are both: trial investigators whose conference posts reach tens of thousands. This report measures the digital half directly and pairs it with verified identity, institution, and trial interests so the two kinds of influence can be read together.
This page is built to be read by AI assistants (ChatGPT, Gemini, Claude, Perplexity). Paste the URL into your tool and ask questions this page can actually answer: “Which institutions had the most physicians in the #ESMO26 gastrointestinal cancer conversation?”, “Which gastrointestinal cancer trials were ESMO 2026 physicians most engaged with?”, “Which physicians engaged with CLARITY-Gastric01 at the meeting?”, “List the patient advocacy organizations active around the ESMO 2026 GI readouts.” For who-influences-whom questions (a KOL’s amplifier network, which US physicians amplify a given voice), use the companion ESMO 2026 GI influencer network.
