BACKGROUND: Endoscopic therapy using radiofrequency ablation (RFA) is a recommended treatment for Barrett's esophagus with high-grade dysplasia (BE-HGD) without a visible lesion which is managed by resection. However, currently, there is no consensus on the management of BE with low-grade dysplasia (BE-LGD) - RFA versus endoscopic surveillance. Hence, we performed a systematic review and meta-analysis of these comparative studies to compare the risk of progression to HGD or esophageal adenocarcinoma (EAC) among patients with BE-LGD treated with RFA versus endoscopic surveillance. METHODS: The primary outcome was to compare the risk of progression to HGD or EAC among patients with BE-LGD treated with RFA versus endoscopic surveillance. RESULTS: Four comparative studies reporting a total of 543 patients with BE-LGD were included in the meta-analysis (234 in RFA and 309 in endoscopic surveillance). The progression of BE-LGD to either HGD or EAC was significantly lower in patients treated with RFA compared to endoscopic surveillance (OR: 0.17, 95% confidence interval [CI]: 0.04-0.65, p = 0.01). The progression to HGD alone was significantly lower in patients treated with RFA versus endoscopic surveillance (OR: 0.23, 95% CI: 0.08-0.61, p = 0.003). The progression to EAC alone was numerically lower in RFA than endoscopic surveillance without statistical significance (OR: 0.44, 95% CI: 0.17-1.16, p = 0.09). Moderate heterogeneity was noted in the analysis. CONCLUSIONS: Based on our meta-analysis, there was a significant reduction in the risk of progression to HGD or EAC among patients with BE-LGD treated with RFA compared with those undergoing endoscopic surveillance. Endoscopic eradication therapy with RFA should be the preferred management approach for BE-LGD.
背景:对于没有可见病变的高级别异型增生(BE-HGD)的 Barrett 食管,内镜下射频消融(RFA)治疗是一种推荐的治疗方法,需要进行切除术。然而,目前对于低级别异型增生(BE-LGD)的治疗方法,即 RFA 与内镜监测,尚未达成共识。因此,我们对这些比较研究进行了系统评价和荟萃分析,以比较 BE-LGD 患者接受 RFA 治疗与内镜监测的进展为高级别异型增生或食管腺癌(EAC)的风险。
方法:主要结局是比较 BE-LGD 患者接受 RFA 治疗与内镜监测的进展为高级别异型增生或 EAC 的风险。
结果:共有 4 项比较研究纳入了 543 例 BE-LGD 患者,进行了荟萃分析(RFA 组 234 例,内镜监测组 309 例)。与内镜监测相比,RFA 治疗组的 BE-LGD 进展为高级别异型增生或 EAC 的风险显著降低(OR:0.17,95%置信区间[CI]:0.04-0.65,p=0.01)。RFA 治疗组进展为高级别异型增生的风险显著低于内镜监测组(OR:0.23,95%CI:0.08-0.61,p=0.003)。EAC 的进展风险在 RFA 组低于内镜监测组,但无统计学意义(OR:0.44,95%CI:0.17-1.16,p=0.09)。分析中存在中度异质性。
结论:根据我们的荟萃分析,与内镜监测相比,RFA 治疗 BE-LGD 患者的高级别异型增生或 EAC 进展风险显著降低。对于 BE-LGD,内镜下消除治疗 RFA 应该是首选的治疗方法。
