近期SABCS大会上一项长期的随机Ⅲ期研究显示:激素受体阴性的诊断早期乳腺癌">乳腺癌的女性患者5年内降低饮食中脂肪摄入会显著降低来自各种原因的死亡风险。

这项研究结果来自一项探索性的女性营养干预研究(Women’sIntERvention Nutrition Study,WINS)。研究者加州大学洛杉矶分校医疗中心生物医学研究所RowanChlebowski教授倡导乳腺癌患者保持体重,增加运动等生活方式干预。前期临床观察性研究显示饮食中脂肪摄入可能与乳腺癌预后相关。Chlebowski教授认为,从科学角度看,很多人会关注这些结果,并决定是否需要进一步随机临床实验证实。对于乳腺癌患者,5%或5磅的体重减轻就会使生存获益,是他们需要考虑的。

WINS实验是1994年正式启动,目的是评估接受标准治疗的早期乳腺癌患者低脂饮食降低对患者无复发生存的影响。研究纳入2437 I期到IIIA期乳腺癌患者,其中,1579例雌激素受体阳性患者,478例雌激素受体阴性患者,362例雌雄激素受体均阴性患者,年龄48-79岁之间,并接受了正规的治疗。准入标准包括有或没有接受放疗的一期手术患者,并进行了系统的治疗(雌激素受体阴性的患者接受化疗,雌激素受体阳性患者接受他莫昔芬联合化疗)。研究启动时,所有参与者均有超过20%的高脂饮食摄入量。

研究者随机分配两组:饮食干预组975例,对照组1462例。饮食干预组要求患者5年内降低脂肪摄入并保证营养均衡,患者需要每两周参加一次注册营养师咨询会,每3个月与营养师联系。干预组接受降脂目标,记录各自的脂肪摄入,研究者会不定时电话检测患者的脂肪摄入情况。5年后,干预组降低了9.2%脂肪摄入,比对照组降低了6磅。

结果:

1.之前报道的WINS数据低脂饮食干预组比对照组降低了24%的复发风险。        

2.总体上,低脂饮食干预组与对照组平均生存无显著差别:干预组死亡率较低 (13.6% vs. 17%; HR=0.94; 95% CI, 0.76-1.2),但没有统计学意义。

3.亚组分析1,低脂饮食干预组ER阴性患者比对照组平均生存明显延长:(13.6 vs 11.7年,HR=0.64; 95% CI, 0.41-0.99),且意义显著。

4.亚组分析2,低脂饮食干预组ER/PR均阴性患者比对照组平均生存时间更长:(14 vs 11.7年,HR=0.46; 95% CI, 0.27-0.78)。        

5. ER阴性和ER/PR均阴性的患者在随机分组后10年或干预结束后5年生存获益达高峰,随机分组后15-20年减弱。

启示:

2014年发表在Journal of the National Cancer InstituteSEER数据显示,73%ER/PR均阴性患者同时伴有HER2阴性,而三阴性乳腺癌患者预后较差,这样,低脂饮食并体重减轻可能会大大增加三阴性乳腺癌生存率。.
