Prognostic Nutritional Index and NSCLC Surgical Outcomes: Meta-Analysis of 11 Studies

Shengjie Wu published a meta-analysis on 2026-05-21 exploring the prognostic value of the Prognostic Nutritional Index (PNI) for patients with non-small cell lung cancer undergoing curative surgery. The analysis includes 11 studies searched from PubMed, Embase, Web of Science, and Cochrane up to October 2025. It calculates pooled hazard ratios for overall, recurrence-free, and cancer-specific survival.

Use Cases

• Assessing the association between PNI and overall survival in NSCLC surgical patients based on the reported hazard ratios.
• Evaluating PNI as a predictor for recurrence-free survival based on the meta-analysis results.
• Investigating the prognostic value of PNI for cancer-specific survival in post-operative NSCLC patients.
• Conducting sensitivity analyses on prognostic studies based on the described heterogeneity assessments.

Strengths

• Includes results from 11 distinct observational studies.
• Reports specific pooled hazard ratios with 95% confidence intervals for three survival outcomes (OS, RFS, CSS).
• Conducted sensitivity analyses and assessed publication bias, with results described as robust.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a 16.1 KB DOCX file, indicating a very small, likely summary-level scope.
