Eight of the 16 genes evaluated were associated with breast cancer risk (IL1A, IL1B, IL1RN, IL2, IL2RA, IL4, IL6 and IL10); four genes were associated with breast cancer risk among women with low NA ancestry (IL1B, IL6, IL6R and IL10), two were associated with breast cancer risk among women with high NA ancestry (IL2 and IL2RA) and four genes were associated with premenopausal breast cancer risk (IL1A, IL1B, IL2 and IL3).

Findings from this large prospective study support a role of oophorectomy for the prevention of premenopausal breast cancer in BRCA2, but not BRCA1 mutation carriers.
Four affected members of the family with sarcoma or premenopausal breast cancer showed increased expression of p53 protein in their normal tissues as detected by immunohistochemistry.
Further studies in larger samples of BC patients of different ages and regions of the country are necessary to provide more definitive TP53p.Arg337His carrier frequencies in different scenarios.
Gynecologic surgeons often perform castration oophorectomy in patients with breast cancer as an increasing number of oncologists are using aromatase inhibitors to treat premenopausal breast cancer.
Here, we report that BCAS3 overexpression in hormone receptor-positive premenopausal breast cancer seemed to be associated with impaired responses to tamoxifen.
Hours/week and MET-hours/week were associated with suggestively increased premenopausal breast cancer risk (MET-hours/week HR<sub>quartile4vs1</sub> = 1.25; 95% CI, 0.98-1.60).
In a previous study, we found a positive association between the UGT1A1 low-transcriptional alleles and premenopausal breast cancer risk in an African-American population.
In addition, African American-predominant CYP1B1 432 Val allele was significantly more often found in the cases than in the controls overall and the HSD17B1 312 Gly allele was specifically associated with premenopausal breast cancer risk (OR=3.00, 95%CI 1.29-6.99).

In summary, our data implicate that despite a significant correlation to cyclin D1 protein expression, amplification status of the CCND1 gene seems a strong independent predictor of tamoxifen response, and possibly agonism, in premenopausal breast cancer.
