Multiscale Cross-Modal Mapping of Molecular, Pathologic, and Radiologic Phenotypes in Lipid-Deficient Clear Cell Renal Cell Carcinoma
Clear cell renal cell carcinoma (ccRCC) exhibits extensive intratumoral heterogeneity on multiple biological scales, contributing to variable clinical outcomes and limiting the effectiveness of conventional TNM staging, which highlights the urgent need for multiscale integrative analytic frameworks. The lipid-deficient de-clear cell differentiated (DCCD) ccRCC subtype, defined by multi-omics analyses, is associated with adverse outcomes even in early-stage disease. Here, we establish a hierarchical cross-scale framework for the preoperative identification of DCCD-ccRCC. At the highest layer, cross-modal mapping transferred molecular signatures to histological and CT phenotypes, establishing a molecular-to-pathology-to-radiology supervisory bridge. This cross-scale paradigm unifies molecular biology, computational pathology, and quantitative radiology into a biologically grounded strategy for preoperative noninvasive molecular phenotyping of ccRCC.

Worse Prognosis
for DCCD-ccRCC subtype compared to NonDCCD-ccRCC, highlighting clinical significance.
| Feature | DCCD-ccRCC | NonDCCD-ccRCC |
|---|---|---|
| ISUP Grade 3-4 | 51.6% | 26.4% |
| T Stage ≥2 | 27.2% | 17.4% |
| Median Age | 65 years | 59 years |
| Males | 76.2% | 62.5% |
| Disease-Free Survival | Significantly lower (P < 0.001) | Significantly higher (P < 0.001) |
| Overall Survival | Significantly lower (P < 0.001) | Significantly higher (P < 0.001) |
Molecular profiling revealed that DCCD-ccRCC is characterized by metabolic reprogramming and dedifferentiated morphology, leading to significantly worse outcomes. This subtype exhibits aggressive clinicopathological features including higher ISUP grades and advanced T stages compared to NonDCCD-ccRCC.
94% AUC
PathoDCCD Internal Validation (0.91 AUC External)
The hierarchical, multi-branch histopathology model (PathoDCCD) accurately predicts molecular DCCD status directly from H&E Whole Slide Images (WSIs). In internal validation, PathoDCCD achieved an AUC of 0.94, with 91% accuracy, 90% sensitivity, and 92% specificity. External validation yielded an AUC of 0.91 and 89% accuracy, demonstrating robust generalization across independent datasets. This model's multi-scale architecture and graph-based spatial aggregation effectively capture intratumoral heterogeneity, which is critical for identifying lipid-deficient areas and necrotic foci.
0.927 AUC
RadioDCCD External Validation for DCCD Status
The CT-based radiomics framework, RadioDCCD, was developed for preoperative identification of DCCD-ccRCC using PathoDCCD-derived pseudo-labels. The LightGBM algorithm with a full integrative model (combining conventional, habitat, and whole-tumor radiomics with clinical variables) achieved the highest discrimination, yielding an AUC of 0.847. External validation with molecular ground-truth labels showed an accuracy of 76.5%, sensitivity of 65.5%, specificity of 80.8%, and an AUC of 0.927. This demonstrates RadioDCCD's strong agreement with pathology-based predictions and its ability to infer molecular labels from imaging data.
Stratifying Prognostic Risk with Cross-Modal Integration
Our multi-scale cross-modal integration refined risk stratification in ccRCC patients. The concordant-DCCD group (both pathology and radiology models predicting DCCD) exhibited the poorest outcomes, with a 36.8% event rate and a median survival of 25.7 months. In stark contrast, the concordant-nonDCCD group showed more favorable outcomes, with a 27.1% event rate and 65.3 months median survival. This highlights the framework's ability to identify patients at high risk of recurrence and progression, even those with favorable conventional staging. Such early identification can guide more intensive surveillance or enrollment into trials for adjuvant therapies, thereby personalizing patient management.
