Abstract

Background

Guidelines recommend endoscopic surveillance for gastric cancer without therapeutic intervention every 3 years in patients with high-risk gastric intestinal metaplasia (GIM). This study aimed to evaluate the efficacy of radiofrequency ablation (RFA) in eradicating high-risk GIM.

Methods

This randomized self-control trial was conducted between June 2020 and February 2023. Patients with histology-verified high-risk GIM were enrolled. The endoscopist performed a biopsy on both the left and right sides of the stomach (five each) by targeting the suspected GIM area where available; otherwise, a random biopsy was taken. Patients were randomized to receive a unilateral RFA on either the left or right side. A repeated RFA on the assigned side was performed every 2–3 months for a total of two to three times. The primary outcome was complete resolution of GIM at 1 year after RFA.

Results

Forty-six patients with a mean age of 66 ± 8 years were analyzed. The complete resolution rate of overall GIM lesions after RFA was significantly higher (49/142; 34/5%) than that in the observation group (29/127; 22.8%, RR = 0.84, 0.73–0.98, p = 0.03). For the subgroup analysis, the complete resolution rate after RFA revealed a significantly higher value than observation only in the incomplete GIM group (24/87; 27.6% vs. 11/82; 13.4%, RR = 0.83, 0.71–0.97, p = 0.02). The percentage of patients with extensive GIM regression after RFA (15/25; 60%) was higher than in the observation group (9/25; 36%) but did not meet statistical significance (RR = 0.62, 0.35–1.09, p = 0.09).

Conclusion

In high-risk GIM, RFA can significantly eradicate incomplete GIM when compared with observation alone.

射频消融治疗高危胃肠化生的疗效：一项随机、自我控制研究。

背景：指南推荐高危胃肠道化生（GIM）患者每3年进行无治疗干预的内镜下胃癌监测。本研究旨在评估射频消融（RFA）在根除高危GIM中的疗效。方法：该随机自我控制试验于2020年6月至2023年2月进行。组织学证实的高风险GIM患者入组。内窥镜医师在胃的左右两侧（各5个）进行活组织检查，目标是可能的GIM区域；否则，进行随机活检。患者随机接受左侧或右侧单侧RFA。每2-3个月在指定一侧重复射频消融，共2-3次。主要终点为RFA后1年GIM完全消退。结果：本组患者46例，平均年龄66±8岁。RFA后GIM整体病变完全消退率显著高于RFA (49/142；34/5%)高于观察组(29/127；22.8%, RR = 0.84, 0.73-0.98, p = 0.03)。在亚组分析中，RFA后的完全解析率明显高于仅观察不完全GIM组(24/87；27.6% vs. 11/82；13.4%, RR = 0.83, 0.71 ~ 0.97, p = 0.02)。RFA后广泛GIM消退的患者百分比(15/25；60%)高于观察组(9/25；36%)，但无统计学意义（RR = 0.62, 0.35-1.09, p = 0.09）。结论：与单纯观察相比，RFA治疗高危GIM能显著根除不完全性GIM。
