Key Takeaway
Interpret radiomics and spatial omics as promising but unvalidated tools for bladder cancer microenvironment characterization.

This systematic review examines the potential of radiomics and spatial omics (single-cell and spatial transcriptomics) to characterize the bladder cancer immune microenvironment. The authors synthesize evidence showing that radiomics enables non-invasive quantification of macroscopic tumor phenotypes through high-throughput extraction of medical imaging features. Spatial omics reveals the fine-grained spatial architecture of cellular and molecular components within the tumor microenvironment. The review also addresses immune cell spatial distribution, stromal heterogeneity, immune checkpoint expression, and therapy response prediction.

The authors identify several limitations, including challenges in multi-omics data integration, model generalization issues, and barriers to clinical translation. The review provides a theoretical foundation and technical outlook for precision medicine in bladder cancer by integrating imaging and spatial omics, but it does not provide clinical trial data or evidence of specific therapeutic efficacy.

Clinicians should interpret these findings as early-stage conceptual work. The evidence is not yet ready for clinical application, and further research is needed to validate these approaches in prospective studies.

How this fits prior evidence

This systematic review extends prior coverage on radiomics in bladder cancer (Jun 2026: radiomics-based machine learning achieves high AUROC for preoperative risk stratification but not yet clinically translatable) by integrating spatial omics to characterize the immune microenvironment. It addresses a gap by proposing a multi-omics framework, though it remains theoretical. It does not directly confirm or contrast findings on cisplatin-based chemotherapy, neobladder techniques, or obesity-related risk.

Researchers have reviewed how combining radiomics with spatial omics can provide a clearer picture of bladder cancer. Radiomics uses medical images to identify large patterns in tumors without invasive procedures. Spatial omics looks at the specific locations of cells and molecules within the tumor area.

By combining these two methods, scientists hope to better understand the immune environment of the cancer. This includes looking at how immune cells are spread out and how they might respond to different treatments. The goal is to move toward more personalized medical strategies for patients.

Because this is a systematic review, it provides a theoretical framework rather than results from a clinical trial. There are still challenges in combining these complex data types and making the models work consistently across different patients. These findings offer a technical outlook for future precision medicine rather than immediate changes to current treatment plans.

What this means for you:
Combining imaging and spatial data may help researchers better map the immune environment of bladder cancer.

Common questions

What is radiomics and how does it help with bladder cancer?

Radiomics involves extracting many features from medical images to quantify tumor characteristics. It allows for a non-invasive way to look at the macroscopic traits of a tumor. This helps researchers understand the broad features of the cancer using standard imaging tools.

What is spatial omics in cancer research?

Spatial omics looks at the fine-grained architecture of cells and molecules within a tumor. It shows exactly where different components are located. This helps scientists see how immune cells are distributed and how they interact with the surrounding tissue.

Can these methods be used to treat patients right now?

These methods currently provide a theoretical foundation for future precision medicine. Because this study is a review of technology rather than a clinical trial, it does not provide evidence for specific treatments or immediate changes to how doctors treat bladder cancer today.

Bladder cancer, a common malignant tumor of the urinary system, possesses a highly heterogeneous tumor immune microenvironment that critically influences disease progression, treatment response, and patient prognosis. The limitations of traditional tissue biopsies have spurred interest in non-invasive, dynamic, and spatially resolved assessment strategies. Radiomics enables non-invasive quantification of macroscopic tumor phenotypes through high-throughput extraction of medical imaging features, while spatial omics technologies, such as single-cell and spatial transcriptomics, reveal the fine-grained spatial architecture of cellular and molecular components within the tumor microenvironment. This review systematically summarizes recent advances in radiomics and spatial omics for characterizing the bladder cancer immune microenvironment, with a focus on their synergistic applications in elucidating immune cell spatial distribution, stromal heterogeneity, immune checkpoint expression, and therapy response prediction. Furthermore, we critically examine the current challenges in multi-omics data integration, model generalization, and clinical translation, and outline future directions driven by artificial intelligence, including multimodal fusion, dynamic monitoring, and personalized therapeutic strategies. This review aims to provide a theoretical foundation and technical outlook for precision medicine in bladder cancer, facilitating the translation of imaging-spatial omics from basic research to clinical practice.
