AI4Path at PathVisions 2025: Three Abstracts Accepted!!!

We are excited to announce that three cutting-edge AI-driven studies from the AI4Path Lab have been accepted for presentation at PathVisions 2025, the premier global conference on digital pathology and AI, taking place October 5–7 in San Diego.

📝 Accepted Abstracts

1. AI-Based Detection of FGFR Mutations from H\&E Whole‑Slide Images in Cholangiocarcinoma
This study explores how deep learning can non-invasively predict fibroblast growth factor receptor (FGFR) mutations directly from H\&E-stained slides of cholangiocarcinoma, potentially guiding targeted therapy decisions in otherwise resource-limited settings.

2. AI-Powered Recurrence Risk Prediction in Invasive Lung Adenocarcinoma Using H\&E Images
This abstract presents a predictive model that stratifies patients by recurrence risk following resection of lung adenocarcinoma, with the goal of supporting personalized surveillance and adjuvant therapy planning.

3. AI-Based Quantification of Histopathological Patterns in Invasive Lung Adenocarcinoma
Here, our team develops automated methods to quantify tissue architectural patterns—such as lepidic, acinar, and solid components—in lung tumors, facilitating standardization and improving prognostic accuracy.

Why These Studies Stand Out

🌟 PathVisions 2025 brings together over 800 experts in AI and digital pathology to drive innovations from pixels to patients through real-world applications.

New Publication Alert: AI4Path Lab Predicts Chemotherapy Response in Triple-Negative Breast Cancer Using Pre-Treatment Biopsies

We’re thrilled to share that a new study from the AI4Path Lab, led by Dr. Muhammad Khalid Khan Niazi, has been accepted and published in Cancers (MDPI) under the Cancer Informatics and Big Data section. 🎉

📖 Paper Title:
Predicting Neoadjuvant Chemotherapy Response in Triple-Negative Breast Cancer Using Pre-Treatment Histopathologic Images
🔗 Read the full article

🔍 What’s the Study About?

Triple-negative breast cancer (TNBC) is one of the most aggressive and difficult-to-treat subtypes of breast cancer, lacking hormone receptor and HER2 targets. While neoadjuvant chemotherapy (NACT) remains the mainstay of treatment, not all patients respond, leading to unnecessary toxicity without benefit.

This study tackles a key clinical question:

Can we predict chemotherapy response before treatment begins—using only routine biopsy slides?

🧠 AI-Powered Predictive Modeling

Our team developed an attention-based multiple instance learning (MIL) model that uses standard hematoxylin and eosin (H\&E)-stained biopsy images to predict pathologic complete response (pCR) to NACT in TNBC patients.

Key Results:

  • 📊 Internal AUC: 0.85 (cross-validation on 174 cases)
  • 🌍 External AUC: 0.78 (validated on an independent cohort of 30 cases)
  • 🔬 Interpretability: High-attention regions aligned with immune-rich tumor areas, especially those enriched in CD8+ T cells, CD163+ macrophages, and PD-L1 expression.

These findings suggest that biologically meaningful features—particularly immune-related components—can be captured from H\&E slides and used to personalize treatment in TNBC.

💡 Why It Matters

This study highlights the growing potential of AI to:

  • ✅ Predict treatment response from pre-treatment data
  • ✅ Reduce unnecessary toxicity from ineffective therapy
  • ✅ Personalize care pathways in aggressive cancers like TNBC
  • ✅ Bridge the gap between routine pathology and precision oncology

The integration of multiplex immunohistochemistry (mIHC) data further strengthens the biological relevance and clinical interpretability of the model—an essential step for translational impact.

AI in Action: Dr. Khalid Niazi Speaks at Wake Forest CAIR Seminar on Prognostic and Predictive Models in Pathology


Date of Event: Thursday, July 24
Event Type: Virtual Seminar
Host: Wake Forest Center for Artificial Intelligence Research (CAIR)
Speaker: Dr. Muhammad Khalid Khan Niazi, Director of AI4Path Lab and Associate Professor of Pathology, The Ohio State University

This past Thursday, July 24th, Dr. Khalid Niazi delivered an insightful talk as part of the Artificial Intelligence in Action seminar series hosted by Wake Forest’s Center for Artificial Intelligence Research (CAIR). The seminar, titled “Prognostic and Predictive Models in Pathology,” attracted clinicians, researchers, and AI enthusiasts eager to understand the evolving role of artificial intelligence in cancer diagnostics and treatment planning.

Dr. Niazi, a leading voice in computational pathology and director of the AI4Path Lab, explored how predictive models—particularly those trained on histopathology images—can revolutionize clinical decision-making. He emphasized the limitations of current foundation models when applied to pathology, advocating instead for the development of histology-informed AI frameworks that are not only accurate but clinically robust.

Dr. Niazi’s seminar was a compelling reminder that AI in pathology is not just about accuracy—it’s about clinical impact. As the field advances, collaboration between data scientists, pathologists, and clinicians will be essential to turn promising models into trusted medical tools.

AI4Path Lab’s HistoChat: A Multimodal Vision‑Language Assistant for Colorectal Histopathology — Accepted in Patterns

We’re thrilled to announce that our PhD student Usman Afzaal—alongside Ziyu Su, Usama Sajjad, Thomas Stack, Hao Lu, Shuo Niu, Abdul Rehman Akbar, Metin Nafi Gurcan, and Muhammad Khalid Khan Niazi—has had his manuscript “HistoChat: Instruction‑Tuning Multimodal Vision Language Assistant for Colorectal Histopathology on Limited Data” accepted by Patterns, the Cell Press open‑access journal for data science.

What Is HistoChat?

HistoChat is a vision‑language AI assistant tailored to analyze colorectal histopathology with only 231 original images. It builds on:

  1. CLIP vision‑language pretraining with 1.137 million pathology image–caption pairs.
  2. A 650 k pretraining dataset to align visual features with LLaVA’s language model via an MLP connector.
  3. L‑Instruct, our 635 k question‑answer dataset generated from 107 k image combinations of the Lizard dataset, ensuring strict image–text coherence and alleviating cell‑clutter issues.

Key Innovations

  • Sophisticated Data Augmentation
    Rather than simple geometric or color tweaks, HistoChat’s pipeline creates image combinations where subsets of cells are masked via inpainting, paired with region‑based cell‑distribution summaries to generate high‑quality QA instructions.
  • Instruction‑Tuning a Multimodal LLM
    We fine‑tune a vicuna‑13B–based LLaVA model using L‑Instruct, enabling open‑ended, pathology‑style queries (e.g., “How many lymphocytes are in the top‑right region?”).

Performance Highlights

On a test split of 115 images (1 618 patches, one QA each), HistoChat outperformed four comparison models (LLaVA1.5, LLaVAMed, QuiltLLaVA, GPT4o) across both automated metrics and expert evaluations:

  • Automated NLP Metrics
    • BLEU: 50.4
    • ROUGE‑L: 51.7
    • BERTScore: 93.3
  • Expert‑Level Accuracy
    • Human evaluation: 69.1% overall accuracy
    • Llama3 evaluation: 60.7% overall accuracy

Ablation (“HistoChat – IC” without image combinations) saw human accuracy drop to 42.9% and Llama3 accuracy to 47.2%, underscoring the power of our augmentation strategy.

Main Contributions

  1. MLLM Fine‑Tuning on 231 Images: Demonstrating strong performance with minimal data.
  2. Coherent Multimodal Augmentation: Generating 107 k augmented images and 635 k QA pairs without image–text mismatches.
  3. Scalable Framework: Easily extendable to other cancer types or modalities, paving the way for broader histopathology applications.

Impact & Next Steps

By showing that an instruction‑tuned multimodal assistant can thrive on limited data, HistoChat offers a template for low‑resource settings—from rare tumor subtypes to under‑resourced clinics. Next, we’ll:

  • Expand to other cancers (e.g., lung, cervix) and staining methods.
  • Integrate spatial transcriptomics for deeper multimodal insights.
  • Explore human‑aligned fine‑tuning (e.g., RLHF) to bolster reliability in clinical deployment.

Please join us in congratulating Usman and the AI4Path Lab team on this exciting acceptance!
