Gut Metagenomic Data from a Breast Cancer Case-Control Study in Vietnam

Shotgun metagenomic sequencing data from 162 breast cancer cases and 370 healthy controls in Vietnam. The dataset includes processed taxonomic and functional profiling of the gut microbiome, with an average of 10.19 million raw sequencing reads per sample. It was authored by Sang M. Nguyen and last updated on 2026-05 21.

Use Cases

• Identify microbial taxa associated with breast cancer risk based on taxonomic profiling data.
• Analyze differences in microbial metabolic pathways between cases and controls based on functional profiling.
• Train predictive models for breast cancer status using gut microbiome composition features.
• Conduct comparative meta-analyses with other gut microbiome studies in different populations.

Strengths

• Includes data from 532 individuals (162 cases, 370 controls), providing a substantial sample size.
• Processing details are specified, including the use of Trimmomatic, Bowtie2, MetaPhlAn 4.1.1, and HUMAnN 3.9.
• Data is openly available under a CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to its collection in Vietnam.
