Observational studies report that physical activity and metformin are associated with improved clinical outcome in patients with cancer. Inflammation is one biological mechanism hypothesized to mediate these associations. In this phase II, multicenter, 2 × 2 factorial trial, 139 patients with breast and colorectal cancer who completed standard therapy were randomized to one of four treatment groups for 12 weeks: exercise alone, metformin alone, exercise and metformin, or control. Inflammation outcomes included high-sensitivity C-reactive protein (hs-CRP), soluble tumor necrosis factor alpha receptor two (sTNFαR2), and IL6. The primary modeling strategy evaluated the trial product estimand that was quantified using a generalized linear mixed model. Compared with control, exercise alone reduced hs-CRP [−30.2%; 95% confidence interval (CI), −50.3, −1.0] and IL6 (−30.9%; 95% CI, −47.3, −9.5) but did not change sTNFαR2 (1.0%; 95% CI, −10.4, 13.9). Compared with control, metformin alone did not change hs-CRP (−13.9%; 95% CI, −40.0, 23.4), sTNFαR2 (−10.4%; 95% CI, −21.3, 2.0), or IL6 (−22.9%; 95% CI, −42.3, 2.0). Compared with control, exercise and metformin reduced sTNFαR2 (−13.1%; 95% CI, −22.9, −1.0) and IL6 (−38.7%; 95% CI, −52.3, −18.9) but did not change hs-CRP (−20.5%; 95% CI, −44.0, 12.7). The combination of exercise and metformin was not synergistic for hs-CRP, sTNFαR2, or IL6. In survivors of breast and colorectal cancer with low baseline physical activity and without type 2 diabetes, exercise and metformin reduced measures of inflammation that are associated with cancer recurrence and mortality.

运动或二甲双胍对乳腺癌和结直肠癌炎症生物标志物的影响:一项随机试验

观察性研究报告说,身体活动和二甲双胍与癌症患者的临床结果改善有关。炎症是一种假设可以调节这些关联的生物学机制。在这项 II 期、多中心、2 × 2 析因试验中,139 名完成标准治疗的乳腺癌和结直肠癌患者随机分为四个治疗组之一,为期 12 周:单独运动、单独二甲双胍、运动和二甲双胍或对照组。炎症结果包括高敏 C 反应蛋白 (hs-CRP)、可溶性肿瘤坏死因子 α 受体 2 (sTNFαR2) 和 IL6。主要建模策略评估使用广义线性混合模型量化的试验产品估计量。与对照组相比,单独运动降低了 hs-CRP [-30.2%; 95% 置信区间 (CI),-50.3,-1。0] 和 IL6 (-30.9%; 95% CI, -47.3, -9.5) 但没有改变 sTNFαR2 (1.0%; 95% CI, -10.4, 13.9)。与对照相比,单独使用二甲双胍没有改变 hs-CRP (-13.9%; 95% CI, -40.0, 23.4), sTNFαR2 (-10.4%; 95% CI, -21.3, 2.0) 或 IL6 (-22.9%; 95% CI, -42.3, 2.0)。与对照组相比,运动和二甲双胍降低了 sTNFαR2 (-13.1%; 95% CI, -22.9, -1.0) 和 IL6 (-38.7%; 95% CI, -52.3, -18.9) 但没有改变 hs-CRP (- 20.5%;95% CI,-44.0,12.7)。运动和二甲双胍的组合对 hs-CRP、sTNFαR2 或 IL6 没有协同作用。在基线体力活动较低且没有 2 型糖尿病的乳腺癌和结直肠癌幸存者中,运动和二甲双胍减少了与癌症复发和死亡率相关的炎症指标。9). 与对照相比,单独使用二甲双胍没有改变 hs-CRP (-13.9%; 95% CI, -40.0, 23.4), sTNFαR2 (-10.4%; 95% CI, -21.3, 2.0) 或 IL6 (-22.9%; 95% CI, -42.3, 2.0)。与对照组相比,运动和二甲双胍降低了 sTNFαR2 (-13.1%; 95% CI, -22.9, -1.0) 和 IL6 (-38.7%; 95% CI, -52.3, -18.9) 但没有改变 hs-CRP (- 20.5%;95% CI,-44.0,12.7)。运动和二甲双胍的组合对 hs-CRP、sTNFαR2 或 IL6 没有协同作用。在基线体力活动较低且没有 2 型糖尿病的乳腺癌和结直肠癌幸存者中,运动和二甲双胍减少了与癌症复发和死亡率相关的炎症指标。9). 与对照相比,单独使用二甲双胍没有改变 hs-CRP (-13.9%; 95% CI, -40.0, 23.4), sTNFαR2 (-10.4%; 95% CI, -21.3, 2.0) 或 IL6 (-22.9%; 95% CI, -42.3, 2.0)。与对照组相比,运动和二甲双胍降低了 sTNFαR2 (-13.1%; 95% CI, -22.9, -1.0) 和 IL6 (-38.7%; 95% CI, -52.3, -18.9) 但没有改变 hs-CRP (- 20.5%;95% CI,-44.0,12.7)。运动和二甲双胍的组合对 hs-CRP、sTNFαR2 或 IL6 没有协同作用。在基线体力活动较低且没有 2 型糖尿病的乳腺癌和结直肠癌幸存者中,运动和二甲双胍减少了与癌症复发和死亡率相关的炎症指标。与对照组相比,运动和二甲双胍降低了 sTNFαR2 (-13.1%; 95% CI, -22.9, -1.0) 和 IL6 (-38.7%; 95% CI, -52.3, -18.9) 但没有改变 hs-CRP (- 20.5%;95% CI,-44.0,12.7)。运动和二甲双胍的组合对 hs-CRP、sTNFαR2 或 IL6 没有协同作用。在基线体力活动较低且没有 2 型糖尿病的乳腺癌和结直肠癌幸存者中,运动和二甲双胍减少了与癌症复发和死亡率相关的炎症指标。与对照组相比,运动和二甲双胍降低了 sTNFαR2 (-13.1%; 95% CI, -22.9, -1.0) 和 IL6 (-38.7%; 95% CI, -52.3, -18.9) 但没有改变 hs-CRP (- 20.5%;95% CI,-44.0,12.7)。运动和二甲双胍的组合对 hs-CRP、sTNFαR2 或 IL6 没有协同作用。在基线体力活动较低且没有 2 型糖尿病的乳腺癌和结直肠癌幸存者中,运动和二甲双胍减少了与癌症复发和死亡率相关的炎症指标。
