Triple negative breast cancer (TNBC) presents clinical challenges due to unknown etiology, lack of treatment targets, and poor prognosis. We examined combined genetic and nutritional risk models of TNBC in 354 breast cancer cases. We evaluated 18 DNA-repair nonsynonymous single nucleotide polymorphisms (nsSNPs) and dietary/nutritional intakes. Multivariate Adaptive Regression Splines models were used to select nutrients of interest and define cut-off values for logistic regression models. Our results suggest that TNBC was associated with 6 DNA-repair nsSNPs, ERCC4 R415Q (rs1800067), MSH3 R940Q (rs184967), MSH6 G39E (rs1042821), POLD1 R119H (rs1726801), XRCC1 R194W (rs1799782), and XPC A499V (rs2228000) and/or deficiencies in 3 micronutrients (zinc, folate, and β-carotene). Combined analyses of these 6 nsSNPs and 3 micronutrients showed significant association with TNBC: odds ratios = 2.77 (95% confidence interval = 1.01-7.64) and 10.89 (95% confidence interval = 3.50-33.89) for 2 and at least 3 risk factors, respectively. To the best of our knowledge, this is the first study to suggest that multiple genetic and nutritional factors are associated with TNBC, particularly in combination. Our findings, if validated in larger studies, will have important clinical implication that dietary modulations and/or micronutrient supplementations may prevent or reverse TNBC phenotype, so tumors can be treated with less toxic therapeutic strategies, particularly in genetically susceptible women.
This research output has an Altmetric Attention Score of 5. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 04 February 2023.
All research outputs
#6,392,547
of 23,283,373 outputs
Outputs from Nutrition and Cancer
#614
of 2,006 outputs
Outputs of similar age
#59,370
of 228,140 outputs
Outputs of similar age from Nutrition and Cancer
#5
of 16 outputs
Altmetric has tracked 23,283,373 research outputs across all sources so far. This one has received more attention than most of these and is in the 72nd percentile.
So far Altmetric has tracked 2,006 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.4. This one has gotten more attention than average, scoring higher than 69% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 228,140 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 73% of its contemporaries.
We're also able to compare this research output to 16 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 68% of its contemporaries.
