TCGA-BRCA: Cross-Tabulation of Hypoxia Groups by Intrinsic Subtype

A 5.5 KB Excel file contains a cross-tabulation analysis of hypoxia groups by intrinsic subtype for the TCGA-BRCA cohort. The dataset was authored by Wenhan Yang and last updated on June 2, 2026. It is derived from The Cancer Genome Atlas Breast Invasive Carcinoma project.

Use Cases

• Analyze the association between tumor hypoxia and intrinsic molecular subtypes based on the cross-tabulation.
• Validate or compare hypoxia-related gene signatures across different breast cancer subtypes.
• Support meta-analyses of TCGA-BRCA data by providing pre-computed cohort-wide median hypoxia groupings.

Strengths

• Data is derived from the authoritative TCGA-BRCA cohort.
• File size is 5.5 KB, making it lightweight and easy to share.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.

Provenance

Source

The Cancer Genome Atlas (TCGA) Breast Invasive Carcinoma (BRCA) project.

Collection Method

Likely contains statistical aggregation (cohort-wide median) of gene expression data related to hypoxia.
