BACKGROUND
In colon cancer patients, obesity, sedentary lifestyle, and high dietary glycemic load have been associated with increased risk of cancer recurrence. High sugar-sweetened beverage intake has been associated with obesity, diabetes, and cardio-metabolic diseases, but the influence on colon cancer survival is unknown.
METHODS
We assessed the association between sugar-sweetened beverage consumption on cancer recurrence and mortality in 1,011 stage III colon cancer patients who completed food frequency questionnaires as part of a U.S. National Cancer Institute-sponsored adjuvant chemotherapy trial. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated with Cox proportional hazard models.
RESULTS
Patients consuming ≥ 2 servings of sugar-sweetened beverages per day experienced an adjusted HR for disease recurrence or mortality of 1.67 (95% CI, 1.04-2.68), compared with those consuming <2 servings per month (P(trend) = 0.02). The association of sugar-sweetened beverages on cancer recurrence or mortality appeared greater among patients who were both overweight (body mass index ≥ 2 5 kg/m(2)) and less physically active (metabolic equivalent task-hours per week <18) (HR = 2.22; 95% CI, 1.29-3.81, P(trend) = 0.0025).
CONCLUSION
Higher sugar-sweetened beverage intake was associated with a significantly increased risk of cancer recurrence and mortality in stage III colon cancer patients.
背景
在结肠癌患者中，肥胖、久坐不动的生活方式以及高膳食血糖负荷与癌症复发风险增加有关。高糖饮料的摄入与肥胖、糖尿病及心血管代谢疾病有关，但对结肠癌患者生存的影响尚不清楚。
方法
我们在美国国立癌症研究所资助的辅助化疗试验中，对1011例III期结肠癌患者进行了评估，这些患者完成了食物频率问卷调查，以评估含糖饮料消费与癌症复发和死亡率之间的关联。采用Cox比例风险模型计算风险比（HR）和95%置信区间（CI）。
结果
每天饮用≥2份含糖饮料的患者，疾病复发或死亡的校正HR为1.67（95%CI，1.04 - 2.68），而每月饮用<2份的患者为参照组（P趋势 = 0.02）。在超重（体重指数≥25kg/m²）且体力活动较少（每周代谢当量任务小时数<18）的患者中，含糖饮料与癌症复发或死亡率的关联似乎更强（HR = 2.22；95%CI，1.29 - 3.81，P趋势 = 0.0025）。
结论
较高的含糖饮料摄入量与III期结肠癌患者癌症复发和死亡风险的显著增加有关。
