Implication

Systematic review and meta-analysis compare diagnostic accuracy in early colorectal cancer, suggesting evaluation methods may impact sensitivity.

Key Points

The aim is to compare the diagnostic accuracy of narrow-band imaging and magnifying chromoendoscopy for assessing submucosal invasion depth in early colorectal cancer.
Conducted a systematic review and meta-analysis of studies comparing NBI and MCE using paired design.
Searched MEDLINE, Embase, and CENTRAL for relevant studies up to September 19, 2025.
Estimated pooled sensitivity and specificity using Bayesian bivariate HSROC model.
Pooled sensitivity for NBI was 75.4% (95% CrI 63.2–85.3) and for MCE was 79.8% (95% CrI 75.9–83.3).
Pooled specificity for NBI was 94.5% (95% CrI 90.8–97.0) and for MCE was 93.8% (95% CrI 91.6–95.6).
Subgroup analysis showed real-time diagnosis had higher sensitivity compared to image-based evaluation.
