BACKGROUND & AIMS: Whether gastric cancer (GC) precursor lesions progress to invasive cancer at similar rates globally remains unknown. We conducted a systematic review and meta-analysis to determine the progression of precursor lesions to GC in countries with low versus medium/high incidence.
METHODS: We searched relevant databases for studies reporting the progression of endoscopically confirmed precursor lesions to GC. Studies were stratified by low (<6 per 100,000) or medium/high (≥6 per 100,000) GC incidence countries. Random-effects models were used to estimate the progression rates of atrophic gastritis (AG), intestinal metaplasia (IM), and dysplasia to GC per 1000 person-years.
RESULTS: Among the 5829 studies identified, 44 met our inclusion criteria. The global pooled estimates of the progression rate per 1000 person-years were 2.09 (95% confidence interval, 1.46-2.99), 2.89 (2.03-4.11), and 10.09 (5.23-19.49) for AG, IM, and dysplasia, respectively. The estimated progression rates per 1000 person-years for low versus medium/high GC incidence countries, respectively, were 0.97 (0.86-1.10) versus 2.47 (1.70-2.99) for AG (P < .01), 2.37 (1.43-3.92) versus 3.47 (2.13-5.65) for IM (P = .29), and 5.51 (2.92-10.39) versus 14.80 (5.87-37.28) for dysplasia (P = .08). There were no differences for progression of AG between groups when high-quality studies were compared.
CONCLUSIONS: Similar progression rates of IM and dysplasia were observed among low and medium/high GC incidence countries. This suggests that the potential benefits of surveillance for these lesions in low-risk regions may be comparable with those of population-wide interventions in high-risk regions. Further prospective studies are needed to confirm these findings and inform global screening and surveillance guidelines.
