Real-World Histopathology Data: The Missing Modality
While clinico-genomic RWD has driven tremendous insights across the drug development lifecycle, there is a critical data modality that has been left untapped due to difficulties with data extraction and analysis - histopathology.
Pathology data plays a pivotal role in precision medicine, elucidating the pathophysiology of diseases, capturing tissue and cellular-level disease manifestations, and quantifying morphological variations influenced by treatment or disease evolution. This essential data is routinely collected at the time of diagnosis and is either stored in physical glass slides or digitally scanned to create whole slide images (WSIs). Pathologists then analyze these slides or images, relying on their expertise and interpretation to guide diagnostic and treatment decisions. Despite the critical information contained within pathology samples and their broad availability, they can be difficult to analyze quantitatively at scale given their inherent data size and complexity.
The integration of pathology into RWD has thus been historically challenging; however, this strategy is advancing rapidly due to the advent of digital pathology and advanced AI-driven image analysis tools, like the natively embedded AI found within PathAI’s Image Management System (IMS), AISight®. By transforming raw, unstructured pathology images into standardized, structured data outputs, pathology data can be seamlessly integrated with clinico-genomic RWD to unlock the full potential of multimodal patient cohorts. These technologies usher in a new era of precision medicine where pathology samples can be rapidly and comprehensively analyzed at the scale necessary to meet global healthcare demands.
The Three Key Components of Real-World Data
Pathology RWD Unlocked: Quantitative Histopathology Data
Pathology stands as an integral component for precise diagnosis of many different diseases. Despite its complexities and intricacies, advancements in digital pathology and AI-driven technologies are transforming what is possible with routine histopathology samples. Today, researchers can use standard hematoxylin and eosin (H&E)-stained samples to obtain a single-cell, spatially-resolved view of tissue structures and cell populations, as well as examine how patients respond to new therapies, understand prognosis, and even predict molecular biomarkers.
PathAI specializes in developing AI-powered products for the analysis of pathology WSIs, transforming unstructured digital images into structured pathology insights to advance precision medicine. This quantitative histopathology data unlocks completely new possibilities alongside other RWD, enabling a comprehensive understanding of the intricacies of diseases at a molecular, cellular, and now histological and anatomical level.

Clinical RWD
Understanding the patient journey is crucial for bolstering RWD as it provides a holistic view of patient healthcare experiences and outcomes. By tracing the sequence of interactions between patients and healthcare systems—from initial symptoms and diagnoses to treatments and follow-ups—RWD captures complexities that controlled clinical trials often cannot replicate. By utilizing clinical data as a modality, this offers significant advantages over traditional clinical trials, which are often expensive, time-consuming, and involve relatively small sample sizes that may not fully represent broader patient populations.
Clinical RWD typically includes data such as:
- Demographics
- Medical History
- Cancer Risk Factors
- Physical Assessments
- Laboratory Tests
- Disease Staging
- Medications/Lines of Therapy
- Surgeries/Biopsies
- Progression/Outcomes
Molecular RWD
Molecular data encompasses a wide array of information, including genome, exome, and transcriptome sequencing data, which are critical components of the multiomics approach for understanding the molecular profiles of patients. Genomics provides insights into the complete DNA sequence and variations within a patient's genome, while transcriptomics offers a snapshot of gene expression levels, revealing how genes are expressed in different contexts. By integrating these layers of molecular data, multi-omics create a comprehensive picture of molecular processes, enabling a deeper understanding of disease mechanisms and patient-specific responses to treatments.
Molecular RWD may include elements such as:
- Whole Genome Sequencing
- Whole Exome Sequencing
- Whole Transcriptome Sequencing
- Single-Cell Transcriptome Sequencing
- Microbiome Sequencing
Unlocking the Future of Precision Medicine with Real-World Insights
RWD that includes clinical, molecular, and pathology data has a unique ability to drive innovation throughout the drug development lifecycle. However, pathology data has been historically underutilized due to its lack of resolution and structure. PathAI’s products are uniquely able to transform raw pathology images into structured pathology data. Together with leading RWD providers, PathAI is integrating AI-powered pathology RWD with clinical and molecular RWD to unlock the future of precision medicine. With these multimodal datasets, researchers and drug developers can gain deeper insights into disease mechanisms, biomarkers strategies, and novel therapeutic targets through comprehensive, multi-scale analyses; ultimately making drug development faster and more cost-effective to improve patient outcomes.
