Multimodal AI generates virtual population for tumor microenvironment modeling
The tumor immune microenvironment (TIME) critically impacts cancer progression and immunotherapy response. Multiplex immunofluorescence (mIF) is a powerful imaging modality for deciphering TIME, but its applicability is limited by high cost and low throughput. We propose GigaTIME, a multimodal AI framework for population-scale TIME modeling by bridging cell morphology and states. GigaTIME learns a cross-modal translator to generate virtual mIF images from hematoxylin and eosin (H&E) slides by training on 40 million cells with paired H&E and mIF data across 21 proteins. We applied GigaTIME to 14,256 patients from 51 hospitals and over 1,000 clinics across seven US states in Providence Health, generating 299,376 virtual mIF slides spanning 24 cancer types and 306 subtypes. This virtual population uncovered 1,234 statistically significant associations linking proteins, biomarkers, staging, and survival. Such analyses were previously infeasible due to the scarcity of mIF data. Independent validation on 10,200 TCGA patients further corroborated our findings.

GigaTIME leverages advanced multimodal AI to translate routine H&E pathology slides into comprehensive multiplex immunofluorescence (mIF) profiles. This innovative cross-modal translation is trained on a massive dataset of 40 million cells with paired H&E and mIF data across 21 protein channels. The framework utilizes a patch-based encoder-decoder architecture built on NestedUNet, ensuring high fidelity in replicating spatial protein activation patterns.

The generated virtual population, comprising 299,376 mIF slides from 14,256 patients across 24 cancer types and 306 subtypes, creates an unprecedented resource for tumor microenvironment (TIME) modeling. This enables detailed investigations into cell states and their spatial configurations without the need for physical mIF.

Case Study: Lung Adenocarcinoma Patient
A representative patient diagnosed with lung adenocarcinoma from the Providence data was analyzed using GigaTIME. The virtual mIF images displayed diverse spatial activation patterns across multiple immune and tumor markers, revealing the distinct cellular functions and states. This patient harbored TMB-H and exhibited high PD-L1 and CD68 activation in the virtual mIF. These findings align with our pan-cancer, lung cancer, and LUAD-specific analyses, providing strong biological fidelity and clinical utility for the virtual population.
Key Takeaway: GigaTIME's virtual population provides granular, patient-specific insights, correlating with known clinical markers and phenotypes, which supports personalized medicine approaches.
GigaTIME's virtual population has enabled population-scale clinical discovery by identifying 1,234 statistically significant associations between virtual protein channels and clinical biomarkers across pan-cancer, cancer-type, and subtype levels. This includes novel insights into protein-biomarker correlations, patient stratification, and the role of spatial and combinatorial protein patterns.
