Wang C, Gu K, Wang F, et al. - Long-term breast cancer survivors who consumed nuts were shown to have experienced better survival, especially disease-free survival (DFS).

• Analysis of 3,449 long-term breast cancer survivors from the Shanghai Breast Cancer Survival Study, to assess the links of nut intake (including peanuts and tree nuts), evaluated at 5-year postdiagnosis, with overall survival (OS) and DFS.

• At 5-year after dietary evaluation (ie, 10-year postdiagnosis), higher OS as well as DFS rates were evident in regular nut consumers.

• Post-multivariable adjustment, a positive association of nut intake with OS and DFS was evident in a dose-response manner, with hazard ratios of 0.72 for OS and 0.48 for DFS, for those with greater than median nut intake vs nonconsumers.

• No variation in the links was found by nut type.

• The links were more obvious in those with a higher total energy intake for OS and in those with early stage (I-II) breast cancers for DFS.

• There was no impact of estrogen receptor/progesterone receptor status or other known prognostic factors on the observed nut-DFS associations.
