Diagnostic Accuracy of Inflammatory Biomarkers for Salivary Gland Tumours: A Systematic Review and Meta-Analysis.

Six studies comprising 338 patients met the inclusion criteria.

The pooled sensitivity and specificity were 0.71 and 0.81 for neutrophil-to-lymphocyte ratio, 0.61 and 0.72 for platelet-to-lymphocyte ratio, 0.74 and 0.78 for SII, and 0.71 and 0.73 for systemic inflammation response index, respectively.

Corresponding AUCs ranged from 0.73 to 0.83, indicating moderate-to-excellent diagnostic accuracy.

Heterogeneity across studies was low (I² = 0%).
