Data Sheet 1_Prognostic significance and model evaluation of the modified advanced lung ca

Data Sheet 1 contains data from a retrospective study of 209 patients with locally advanced resectable gastric cancer who underwent neoadjuvant chemotherapy followed by surgery. The study, authored by Weidong Xie and uploaded to figshare in June 2026, investigates the prognostic significance of the modified Advanced Lung Cancer Inflammation Index (mALI) for overall survival. It includes results from Cox regression, Bayesian sensitivity analyses, and the internal evaluation of a postoperative nomogram.

Use Cases

• Validate the prognostic value of the modified Advanced Lung Cancer Inflammation Index (mALI) based on the study's findings.
• Build or benchmark survival prediction models for gastric cancer patients undergoing neoadjuvant chemotherapy.
• Assess the clinical utility of a nomogram incorporating mALI, chemotherapy regimen, and pathological stage.
• Investigate the relationship between sarcopenia-related indices and survival in advanced gastric cancer.

Strengths

• Dataset is based on a cohort of 209 patients, providing a specific sample size.
• Analysis includes multiple validation methods: Cox regression, Bayesian sensitivity, and internal nomogram evaluation with a C-index of 0.765.
• The study defines specific mALI cut-off values (10.5 for males, 12.3 for females) derived from the data.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single retrospective study and may reflect inherent selection biases.
