摘要

背景：乳腺癌（BC）是全球女性癌症相关死亡的主要原因。富含单不饱和脂肪和多酚的橄榄油与降低BC风险有关，但流行病学证据仍然有限。本研究在意大利成年女性中调查了橄榄油消费与BC风险之间的关系，并对这种关系进行了系统回顾。方法对Moli-sani研究（2005-2010）的11442名女性（平均年龄54.7 ± 11.6岁）进行纵向分析。Cox比例风险模型用于估计与橄榄油消费相关的BC风险。通过检索截至2024年10月的Scopus、EMBASE、PubMed和MEDLINE数据库，对观察性研究和随机对照试验进行系统评价。结果与较低的橄榄油摄入量（≤2 tbsp./d）相比，总体、绝经前和绝经后BC中最高摄入量（3 tbsp./d）的多变量调整hr分别为0.71（95 %CI 0.48-1.05）、0.80（95 %CI 0.28-2.28）和0.70（95 %CI 0.46-1.08）。增加1汤匙。每日摄入橄榄油与较低的ER和PR乳腺癌风险相关(HR=0.32；95 %CI 0.13-0.77)，特别是ER病例(HR=0.32；95年 %可信区间0.15 - -0.69);此外，与食用橄榄油最少的人群相比，食用橄榄油最多的人群发生HER2 - BC的风险较低(HR=0.54；95 %可信区间0.31 - -0.96)。系统评价包括13项观察性研究（11项病例对照研究和2项前瞻性研究）和1项随机对照试验。虽然病例对照研究和随机对照试验表明橄榄油的食用有保护作用，但纵向研究报告没有关联。Moli-sani研究的结果表明，橄榄油的摄入量与激素受体阴性乳腺癌（尤其是ER亚型）的风险呈负相关，但对总体乳腺癌风险尚无定论。系统评价显示，病例对照研究更多地报告了保护性关联，而前瞻性研究并未一致支持这一发现。

Olive oil consumption and risk of breast cancer: Prospective results from the Moli-sani Study, and a systematic review of observational studies and randomized clinical trials

Background

Breast cancer (BC) is the leading cause of cancer-related death among women worldwide. Olive oil, rich in monounsaturated fats and polyphenols, has been linked to a reduced BC risk, but epidemiological evidence remains limited. This study examined the association between olive oil consumption and BC risk in a large cohort of adult Italian women and conducted a systematic review on this association.

Methods

Longitudinal analyses were performed on 11,442 women (mean age 54.7 ± 11.6 years) enrolled in the Moli-sani Study (2005–2010). Cox proportional hazard models were used to estimate BC risk in relation to olive oil consumption. A systematic review was conducted by searching Scopus, EMBASE, PubMed, and MEDLINE databases up to October 2024 for observational studies and RCTs.

Results

Compared with lower olive oil consumption (≤2 tbsp./day), multivariable-adjusted HRs associated with highest intake (>3 tbsp./d) for overall, premenopausal, and postmenopausal BC were 0.71(95 %CI 0.48–1.05), 0.80 (95 %CI 0.28–2.28), and 0.70 (95 %CI 0.46–1.08), respectively.

An increase of 1-tbsp./d of olive oil was associated with a lower risk of ER and PR breast cancers (HR=0.32; 95 %CI 0.13–0.77), particularly ER cases (HR=0.32; 95 %CI 0.15–0.69); additionally, a lowered hazard of HER2– BC incidence was observed at highest consumption of olive oil compared to the bottom category (HR=0.54; 95 %CI 0.31–0.96).

The systematic review included 13 observational studies (11 case-control and 2 prospective) and 1 RCT. While case-control studies and the RCT suggested a protective effect associated with olive oil consumption, longitudinal studies reported no association.

Conclusions

Findings from the Moli-sani Study suggest an inverse association between olive oil consumption and the risk of hormone receptor-negative breast cancers, particularly ER subtype, while results were inconclusive for overall BC risk. The systematic review revealed that case-control studies more frequently reported a protective association, whereas prospective studies did not consistently support this finding.
