Colorectal Cancer Patient Data on Malnutrition, Immunity, and Tumor Microbiota

A prospective pilot study of 43 colorectal cancer patients from July 2017 to August 2021, evaluating preoperative nutritional status, intratumoral immune phenotypes, and tumor-associated microbiota. The dataset, authored by Federica Perillo and shared under a CC-BY-4.0 license, includes biochemical, anthropometric, and nutritional profiles, with microbiota analysis performed on a subset of 8 patients.

Use Cases

• Investigating associations between malnutrition screening scores and altered T cell phenotypes based on immune profiling data.
• Analyzing links between neutrophil lymphocyte ratio (NLR) and specific bacterial genera like Bacteroides and Prevotella mentioned in the results.
• Modeling the relationship between preoperative nutritional status and tissue-infiltrating neutrophil levels in colorectal cancer patients.
• Exploring potential biomarkers for suppressed anti-tumor immunity based on combined nutritional and microbiota profiles.

Strengths

• Prospective study design with 43 enrolled patients provides a structured clinical cohort.
• Multimodal data includes biochemical, anthropometric, nutritional, immune phenotype, and microbiota analysis.
• Specific time range from July 2017 to August 2021 defines the study period.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Microbiota analysis was performed on a small subset of only 8 patients.
