Potential Role of Agentic Artificial Intelligence in Toxicologic Pathology
This white paper synthesizes expert perspectives from a 2025 STP roundtable to explore how agentic artificial intelligence can address data fragmentation and reporting challenges in toxicologic pathology through coordinated workflows, while outlining a phased adoption roadmap and emphasizing the need for cross-sector collaboration to establish standards for safe and trustworthy integration.

The Big Picture: A Team of Super-Intelligent Interns
Imagine you are a Toxicologic Pathologist. Your job is like being a master detective who looks at tiny slices of tissue (from animals in drug trials) to figure out if a new medicine is safe for humans. You have to look at thousands of microscope slides, check blood test results, read old medical files, and write a massive report explaining your findings.
Right now, this job is exhausting. You are drowning in paperwork, data is scattered in different filing cabinets (some digital, some paper), and you have to do it all under a tight deadline. It's like trying to cook a five-course meal while someone keeps handing you new ingredients and changing the menu every five minutes.
This paper is about a new kind of technology called "Agentic AI."
Instead of just a calculator or a spell-checker, think of Agentic AI as a team of highly organized, super-smart interns who work together to help you. They don't replace you (the master detective); they do the boring, heavy lifting so you can focus on the big clues.
What is "Agentic AI"? (The Orchestra Conductor)
The paper explains that old AI tools were like a single musician playing one note. They could count cells on a slide or find a specific word in a document, but they couldn't connect the dots.
Agentic AI is like a full orchestra conductor.
- Intern #1 (The Librarian): Runs to the library, grabs the old drug reports, and finds similar cases.
- Intern #2 (The Data Analyst): Looks at the blood test numbers and the microscope slides to find patterns.
- Intern #3 (The Writer): Takes all that info and writes a first draft of the report.
- Intern #4 (The Quality Checker): Reads the draft to make sure nothing is missing or contradictory.
All these "agents" talk to each other and work in sync. They bring you a complete, organized folder of information and a draft report, but you are the conductor. You listen to them, check their work, and make the final decision.
The Problems They Are Solving
The paper lists four main headaches that pathologists face, and how this AI team helps:
- The "Scattered Filing Cabinet" Problem: Data is everywhere—on your computer, in the cloud, in PDFs, in spreadsheets.
- The Fix: The AI team acts like a universal translator. They pull everything into one place so you don't have to jump between ten different windows.
- The "Time Crunch" Problem: You have to write huge reports very fast.
- The Fix: The AI writes the boring parts (like listing the animals or the methods used) instantly. This saves you hours of typing, letting you focus on the complex medical reasoning.
- The "Reinventing the Wheel" Problem: You might have seen a specific type of liver damage five years ago, but you can't remember the details.
- The Fix: The AI remembers everything. It can instantly say, "Hey, we saw this exact thing in a study from 2019, and here is what we concluded."
- The "Human Error" Problem: When you are tired and rushed, you might miss a small detail.
- The Fix: The AI acts as a safety net, double-checking numbers and flagging weird inconsistencies before you sign the report.
The Big Hurdles: Why We Can't Just Turn It On Tomorrow
Even though this sounds amazing, the paper says we can't just flip a switch. There are three big walls to climb:
- Trust (The "Hallucination" Fear): Sometimes AI makes things up. If the AI says, "This drug caused a tumor," but it's lying, that's a disaster.
- The Solution: The AI must show its work. It needs to say, "I found this tumor because of X, Y, and Z, and here is the page in the book where I found it." If it can't prove it, you don't trust it.
- The Rules (The "Red Tape"): In drug testing, everything must be perfect and traceable (GLP rules). If the AI makes a mistake, who is responsible?
- The Solution: We need to test these AI tools carefully in "practice mode" first (on non-regulated studies) before letting them help with official drug approvals.
- Privacy (The "Secret Sauce"): Drug companies are terrified of their secret data leaking out to the public or competitors.
- The Solution: The AI needs to live inside a secure, locked-down digital vault (a "firewall") so it can learn without stealing secrets.
The Roadmap: How We Get There
The paper suggests a step-by-step plan, like learning to ride a bike:
- Phase 1: Training Wheels. Start using the AI on small, low-risk projects (like early research) where a mistake isn't a disaster. See how it works.
- Phase 2: The Test Drive. Have the AI write drafts for real studies, but have a human expert check every single word. Measure how much time it saves.
- Phase 3: The Full License. Once everyone trusts the AI and the rules are set, let it help write official reports for drug approvals.
- Phase 4: The Community. All the big drug companies and regulators need to talk to each other to create a "rulebook" so everyone uses the AI the same way.
The Bottom Line
This paper isn't saying "Robots will take our jobs." It's saying, "Robots can carry the heavy boxes so we can focus on the art of solving the mystery."
The goal is to give toxicologic pathologists a "super-pilot" assistant that handles the data chaos, allowing the human experts to do what they do best: use their brains to make life-saving decisions about drug safety. But to get there, we need to build trust, follow the rules, and work together.
