摘要
The purpose of this study was to optimize the surveillance frequency and period for efficient detection of early gastric cancer (EGC) after Helicobacter pylori (HP) eradication.Data from patients with eradicated HP infection were extracted from the endoscopy databases of two institutions from January 2016 to March 2021. The patients were divided into a close follow-up group with frequent surveillance after eradication and an open follow-up group with an intermittent surveillance method, and the cases of post-eradication EGC found in the two groups were analyzed.Thirty-six out of 9,322 patients (0.39%) in the close follow-up group and 20 out of 11,436 patients (0.17%) in the open follow-up group were found to have EGC. The cumulative incidence of EGC after eradication was significantly higher in the close follow-up group (p = 0.004). The duration between eradication and EGC detection was significantly shorter in the close follow-up group (51.7 vs. 90.5 months, p = 0.002). A logistic regression model revealed that duration after eradication was an independent predictor for detecting EGC in the close follow-up group (p = 0.045). A Cox proportional hazards model revealed that the close follow-up strategy was effective in patients with an eradication duration of less than 65 months to identify EGC (p = 0.015), but there was no difference between the two strategies in patients with an eradication duration of more than 65 months (p = 0.624).Frequent surveillance after HP eradication is efficient for the early detection of EGC during the first 65 months.
