AI in Oncology 2026: 6 Community Trends | KOL Pulse

Written by Brian Shields | Oct 31, 2026, 9:17:22 AM

Oncology didn't wait for permission.

Across the last nine editions of the KOL Pulse AI in Oncology Digest, oncologists have described AI in their own words. It is already in the clinic, at the desk, in the trial workflow, and inside the peer-review stack. The question in the community is no longer whether to use AI. It is who curates it, who is liable when it's wrong, and what still needs a human.

Yan Leyfman, MD (@YLeyfman) put it plainly: "The oncologist of the AI era cannot simply be an AI user. We must become AI curators." (Aug 31 edition)

Welcome to the Curator Era. Here are the six trends defining it.

How oncology knowledge moves now: from publication-first to curator-first.

1. What is replacing UpToDate in oncology? Free AI knowledge layers, and they're going global

Oncology's reference stack is being rebuilt in real time. Aaron Goodman, MD (@Papa_Heme) said it bluntly: "UpToDate is going the way of the old medical textbook." (Aug 12) Weeks later he described calling "a lot less ID consults now with AI." Paul Sax, MD (@PaulSaxMD) called that "fascinating," and said it raises important questions for the cognitive specialties (Oct 2).

The institutions are moving too. Memorial Sloan Kettering and OpenEvidence announced an integration inside MSK's Epic workflow, and they are bringing OncoKB into OpenEvidence for physicians outside MSK (Sep 18). OpenEvidence and Anthropic are bringing a specialized version free to clinicians in about 100 low- and middle-income countries (Oct 2). Vineeta Agarwala (@vintweeta) of a16z Bio called it "sub-specialty knowledge becoming more democratized with AI."

Why it matters: Whoever controls the default answer at the point of care now shapes oncology practice worldwide.

2. How many oncologists use AI without a policy? Most of them

Adoption came before governance. In Leyfman's survey of 52 U.S. oncology clinicians, 83% used AI independently on personal platforms, 71% reported no institutional AI governance policy, and 77% worked without institutional oversight (Aug 31). Doximity's figure of 66% physician AI adoption points the same way (Aug 25).

The sharpest finding is what Leyfman calls the verification paradox. Nearly everyone intended to verify AI recommendations, yet 23% would still have followed an intentionally embedded dosing error. The ASCO Post flagged a related problem: automation bias that persists even when physicians get outcome feedback (Aug 12).

Why it matters: CAR-T, bispecifics, and MRD decisions are exactly where "confidently incorrect" carries the high stakes.

3. Do AI agents improve clinical trial enrollment? Not on their own

This is the most important null result of the season. Roupen Odabashian, MD (@RoupenMD) described a randomized trial in 20,707 patients where oncologists were notified about genomic trial matches. "The notifications worked. Enrollment did not move." His diagnosis: "a logistics problem wearing an information problem's clothes." (Sep 7) Benjamin Herzberg, MD (@bherzbergmd) agreed: "you only go as fast as your slowest step. Right now that's enrolling trials."

Agents are still landing where information is the bottleneck. Odabashian launched OncoPulse, an AI agent that tracks the oncology topics you pick. Jason Locasale (@LocasaleLab) had Astra draft five NIH R01 proposals in about an hour for roughly $20 of compute. Mount Sinai deployed Triomics-based trial matching across seven sites, and Odabashian's question is whether enrollment numbers actually move (Sep 22). At ASTRO, Kishan Patel (@KM__Patel) presented agentic AI across 14 radiation oncology disease sites: "AI shows promise, but physician oversight matters." (Oct 2)

Which AI tools are oncologists using and building?

The digest also shows which tools oncologists name in their own posts, and what some of them are building themselves.

AI tools oncologists describe in their posts, from the AI in Oncology Digest.
  • OpenEvidence: point-of-care evidence search, now inside MSK's Epic workflow with OncoKB (Sep 18) and free in about 100 low- and middle-income countries with Anthropic (Oct 2).
  • ChatGPT for Clinicians: OpenAI's clinician plan with free GPT-6 Astra access for verified U.S. clinicians (Sep 18).
  • Abridge: ambient scribe. Jeff Ryckman, MD said it saves him "about an hour a day doing notes" (Aug 18).
  • Copilot: inbox and activity summaries, shared by Talha Badar, MD (Sep 18).
  • Triomics: oncology-specific trial matching, deployed across seven Mount Sinai sites (Sep 22).

Built by physicians: tools oncologists shared in the AI in Oncology Digest.
  • RAS dashboard by David Hong, MD of MD Anderson, built with Claude Code (Aug 12).
  • OncoPulse by Roupen Odabashian, MD, a free AI agent that tracks the oncology topics you pick (Sep 7).
  • A WCLC 2026 abstract database by Masahiro Torasawa, MD, PhD, built mostly with GPT-6 Astra (Sep 7).
  • Guideline-grounded agentic AI across 14 radiation oncology disease sites, presented at ASTRO 2026 by Kishan Patel, MD (Oct 2).
  • Marrow Defense, a CAR-T tower defense game by Andrew Portuguese, MD, built mostly locally with Qwen and polished in Codex (Aug 25).
  • UrologyWatch by Alexander Kutikov, MD, one place for daily urology news, events and podcasts (Oct 2).

What's new this month? Oncology AI applications from the feed

Since our last digest edition, oncologists have shared a fresh wave of tools they built, use or are watching.

New oncology AI applications shared by physicians on X, October 2026.
  • OncoPulse slide builder. Roupen Odabashian, MD: "You write one prompt. It pulls the studies from PubMed and builds the deck." (Oct 18)
  • A local AI scribe. Odabashian again: "Wi-Fi off, it still transcribes the visit and writes the note, all on my laptop." Built with Claude, driven by doctors' privacy and cost concerns. (Oct 19)
  • CarcinoS. Jeff Ryckman, MD on a tool built by Jeff Brower, MD: it "finds the salient updates for both radiation and medical oncology, and a practicing oncologist makes the final call on every one." (Oct 30)
  • Agentic AI for immunotherapy adverse events. Eric Topol, MD: "Agentic AI detected adverse events of cancer immunotherapy, which are frequently missed, in real world medicine." (Oct 29)
  • Sequential-diagnosis AI. Yan Leyfman, MD on Nori et al.: 83.2% accuracy on NEJM Clinicopathological Conference cases vs 36.1% for generalist physicians, with the caveat that "the findings remain limited to controlled benchmark settings." (Oct 23)
  • OpenEvidence at scale. Bertalan Meskó, MD, PhD shared a study of almost a million U.S. clinicians and 271 million queries, in which oncology and hematology users had a higher-than-average share (use ratio 2.00). (Oct 19) OpenEvidence itself says over 85% of MSK oncologists use it, now with OncoKB built in (Oct 22).
  • Multi-agent workflows. Jeff Ryckman, MD splits his work between Grok Bot and Cursor (more below).

How one radiation oncologist splits the work between Grok Bot and Cursor

Jeff Ryckman, MD, a radiation oncologist and former medical physicist, has been open about how he builds. On October 8 he wrote: "Just downgraded Claude and ChatGPT and funneled the price difference into Cursor and Grokbots." Asked about it two days later, he described the division of labor: "Grok Bot holds the task, skills, context, and what not to touch. Cursor does the coding." And the rule he uses: "If I can define the job and leave it, I send it to the bot. If I need to iterate in real time, I stay in Cursor."

It is the Curator Era in miniature. The physician defines the job and decides what the agent may not touch, and the tools do the work.

4. Can AI detect cancer earlier? Yes, but biomarkers face a validation tax

The detection signal is real. Eric Topol, MD (@EricTopol) highlighted AI detecting pancreatic cancer up to 3 years before current diagnosis (Aug 31). He also flagged Oncoformer, a multimodal EHR plus chest X-ray model in 3.67 million people that predicted cancer at least a year before diagnosis (AUROC 0.869 across all cancers) (Sep 22). Other work includes a histology model that reads breast margins in seconds and an MSK model predicting smoldering myeloma progression at IMS26 (Oct 2).

The community is also asking the hard question. Mali Barbi, MD (@DrBarbiOnc) said AI-counted TILs may be a "thermometer, not target," and noted the only thing that held up was spatial arrangement. Ilana Schlam, MD (@IlanaSchlam) reported that AI TILs in NSABP B-41 were associated with pCR and may complement manual scoring (Aug 25).

Why it matters: Precision AI has to change decisions, not just describe the tumor back to us.

5. Is AI breaking peer review? The community thinks it's straining

Samer Al Hadidi, MD (@HadidiSamer) published "Peer-Unreviewed: When the Thread Replaces the Paper" in Annals of Internal Medicine (Aug 25). JAMA issued guidance on where AI assistance ends and authorship begins, and Yüksel Ürün, MD (@DrYukselUrun) noted "that line will keep moving" (Aug 12). Jeff Ryckman, MD flagged an EviCore denial built on AI-hallucinated literature (Aug 18). Data scientist Selçuk Korkmaz went further: "AI just killed the peer-review." (Oct 2)

Why it matters: When papers, reviews, and denials can all be machine-written, verified human signal becomes the scarce asset.

It's the same shift we described in The KOL Layer Now Loads Before the Publication Layer in Oncology.

6. What does oncology AI still need? Verified oncologist signal

Every trend above points to the same gap. Curators need trustworthy inputs: what credentialed oncologists actually say, attributed and verbatim. That is the backbone of the AI in Oncology Digest. Oncology-hematology also led specialty AI use in the JAMA OpenEvidence analysis.

What should pharma and medical affairs do now?

  • Listen to the curators. The oncologists shaping AI norms are posting in public now. Track them by name on our KOL hub.
  • Treat AI answers as a channel. If OpenEvidence-style tools are the new reference stack, your evidence has to be legible there.
  • Measure what moves. As the enrollment RCT showed, identification is not impact. Our trial profiles show which oncologists react to each readout.
