JCO:多喝咖啡,结肠癌3期病人死亡率和肿瘤复发率降低!

2015-08-19 陈说 译 MedSci原创

来自达纳法伯癌症研究所研究人员一项新的研究表明,若结肠癌3期的患者经常喝含咖啡因的咖啡,则可显著降低机体肿瘤复发的几率,并提高患者生存率。且咖啡摄入量为4杯/天或更多则对患者的身体功能越好。这项研究发表在临床肿瘤学杂志上。达纳胃肠肿瘤研究中心主任Charles Fuchs说道:“我们发现,饮用咖啡的人患癌风险低,且若患癌症则治愈几率更大”。美国人平均每天要喝三杯咖啡,54%的美国人每天喝18杯咖啡

来自达纳法伯癌症研究所研究人员一项新的研究表明,若结肠癌3期的患者经常喝含咖啡因的咖啡,则可显著降低机体肿瘤复发的几率,并提高患者生存率。且咖啡摄入量为4杯/天或更多则对患者的身体功能越好。这项研究发表在临床肿瘤学杂志上。


达纳胃肠肿瘤研究中心主任Charles Fuchs说道:“我们发现,饮用咖啡的人患癌风险低,且若患癌症则治愈几率更大”。

美国人平均每天要喝三杯咖啡,54%的美国人每天喝18杯咖啡。在如此庞大的数字面前,研究人员重点关注咖啡等热饮料也不足为奇。

饮用咖啡会为机体带来一系列问题。既往研究表明,咖啡摄入过多会增加认知障碍的风险,但会降低男性勃起障碍的风险;对女性而言,研究人员发现,对于患有乳腺癌且服用他莫昔芬的患者若饮用咖啡至少2杯/天,则复发几率减半。

在胰岛素水平高于正常的人群中,结肠癌更容易复发,同时饮用咖啡量多也会减少患2型糖尿病的风险并增加机体胰岛素的敏感性。然而,咖啡摄入量对结肠癌患者的的生存率和复发率的影响尚无人知晓。

研究人员进行了一项前瞻性研究,他们对953例3期结肠癌患者在接受化疗后6个月内进行了一项膳食问卷调查。关注的主要目标是咖啡、不含中草药成分的茶饮、和咖啡因对患者肿瘤复发率和死亡率的影响。

他们发现,在随访期间,每天喝四杯或更多(咖啡因含量至少为460mg)的患者,比不喝咖啡的患者肿瘤复发的几率要低42%、死亡率低33%。更进一步的研究分析表明,降低癌症患者肿瘤复发率和死亡率的是咖啡中的咖啡因,而不是咖啡中的其他成分。

但是对于确切机制,研究人员尚不清楚,但研究人员认为,咖啡因的摄入可能会增加胰岛素敏感性。这意味着身体分泌胰岛素会稍减少,这样有可能减少机体的炎症反应(导致机体出现癌症或糖尿病的高危因素)。鉴于研究尚未完成,作用的确切机制尚不明确,因此研究人员尚未公开宣布最佳的日常咖啡摄入量。

Fuchs教授说道:“如果你是位结肠癌患者,同时你又很喜欢喝咖啡,那么你可以继续喝咖啡;但是如果你之前没有喝过咖啡,那么你就不要贸然地和咖啡,至少要跟你的主管医生商量沟通一下。”
