Understanding This Report
Questions This Report Answers

What does this data show?

A verified, classified map of the #ESMO26 breast cancer conversation across 25 breast cancer trials: 677 accounts from curated posts, including 307 physicians — 107 US physicians and 200 international colleagues, from 38 physician countries including the US (India, Turkey, Brazil, Japan lead outside the US). Institutional clusters are visible in the conference conversation: Dana-Farber Cancer Institute (11), Cleveland Clinic (4), Moffitt Cancer Center (4), City of Hope (3). Trial interest concentrates around NATALEE (157 physicians), TALENT (98 physicians), postMONARCH (83 physicians). 27 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.

How can a KOL learn from this report?

Benchmark your own #ESMO26 breast cancer presence against the 307 physicians mapped here: are your trials of interest among the crowded conversations (NATALEE, TALENT, postMONARCH) 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.

What does a worked example of using this data look like?

An MSL following up after ESMO 2026: Dana-Farber Cancer Institute alone had 11 physicians in the #ESMO26 breast cancer conversation. Cross-reference the trial section — NATALEE (157 physicians), TALENT (98 physicians), postMONARCH (83 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.

How can medical affairs and pharma teams use this report?

As post-meeting follow-up planning grounded in this page's own numbers: the category and region breakdowns surface the 107 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 57 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.

Why is social influence mapping important in oncology?

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 breast readouts — Dana-Farber Cancer Institute and Cleveland Clinic clusters, 27 active patient advocacy organizations, and NATALEE-focused physician groups.

What is the difference between a KOL and a Digital Opinion Leader?

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.

How can I use this report with my favorite AI tool?

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 breast cancer conversation?”, “Which breast cancer trials were ESMO 2026 physicians most engaged with?”, “Which physicians engaged with NATALEE at the meeting?”, “List the patient advocacy organizations active around the ESMO 2026 breast readouts.” For who-influences-whom questions (a KOL’s amplifier network, which US physicians amplify a given voice), use the companion ESMO 2026 Breast influencer network.
