葡萄糖类-1受体激动剂 (GLP-1RA) 在试验中没有显示整体癌症风险增加. 然而,与肥胖相关的癌症的潜在减少以及增加甲状腺癌风险的信号需要进一步调查.
科学领域:
- 内分泌学和新陈代谢学
- 在瘤学瘤学.
- 临床试验 研究 研究 临床试验 临床试验
背景情况:
- 类似葡萄糖类-1受体激动剂 (GLP-1RA) 广泛用于治疗2型糖尿病和肥胖症.
- 人们对它们对瘤致癌风险的潜在影响表示担忧,需要严格评估.
研究的目的:
- 评估GLP-1 RA使用与发展整体和特定类型癌症的风险之间的关联.
- 为了比较GLP-1RA的瘤风险与随机对照试验 (RCT) 中的比较治疗.
主要方法:
- 对RCT进行了全面的元分析,将GLP-1RA与糖尿病和/或肥胖的对照组进行比较.
- 包含的试验至少持续52周,终点集中在整体癌症和个体恶性瘤的发病率上.
主要成果:
- 对50项RCT的元分析发现,GLP-1治疗RA的整体癌症风险没有显著差异 (MH-OR1.05,95%CI [0.98,1.13]).
- 在肥胖症试验中观察到子宫癌风险的显著降低 (MH-OR 0.24,95% CI [0.06,0.94]),但在糖尿病试验中没有.
- 特别是在长期研究中,发现甲状腺癌风险增加 (MH-OR 1.55, [1.05, 2.27]),在短期试验中发现结直肠癌风险显著增加 (MH-OR 1.27 [1.03, 1.57]).
结论:
- 根据目前的临床试验数据,GLP-1RA似乎不会显著影响大多数癌症的风险.
- 建议可能减少与肥胖相关的癌症,但对甲状腺癌风险的担忧信号需要进一步的专门研究.
- 在较短的试验中观察到的结直肠癌风险增加可能与由于常见的GLP-1RA副作用而增加的诊断程序有关.
