    Abstract: We assessed whether variants in 22 oxidative stress-related genes are associated with mortality of breast cancer patients and whether the associations differ according to radiotherapy. Using a prospective cohort of 1348 postmenopausal breast cancer patients, we estimated hazard ratios (HR) and 95% confidence intervals (CI) for 109 single nucleotide polymorphisms (SNPs) using Cox proportional hazards regression. Validation of results was attempted using two Scandinavian studies. Eleven SNPs in MT2A, NFE2L2, NQO1, PRDX1, and PRDX6 were significantly associated with overall mortality after a median follow-up of 5.7 years. Three SNPs in NQO1 (rs2917667) and in PRDX6 (rs7314, rs4916362) were consistently associated with increased risk of dying across all three study populations (pooled: HRNQO1_rs2917667 1.20, 95% CI 1.00-1.44, p = 0.051; HRPRDX6_rs7314 1.16, 95% CI 1.00-1.35, p = 0.056, HRPRDX6_rs4916362 1.14 95% CI 1.00-1.32, p = 0.062). Potential effect modification by radiotherapy was found for CAT_rs769218. In conclusion, genetic variants in NQO1 and PRDX6 may modify breast cancer prognosis.

    Abstract: BACKGROUND AND AIM: In breast cancer patients, intraoperative bone marrow puncture (BMP) with positive detection of disseminated tumor cells has been reported to predict unfavorable clinical outcome due to increased risk of recurrence. In this study, we prospectively assessed BMP-associated untoward side-effects. METHODS: Fifty-eight consecutive breast cancer patients were prospectively explored after intraoperative BMP for postoperative pain (visual analogue scale, VAS) and complications in terms of infection, hematoma, and sensibility disorder. Furthermore, the impact of BMP on hospital stay duration was analyzed in 254 patients. RESULTS: In all subgroups analyzed, during five postoperative days patients complained about minor pain only at the site of BMP (VAS 〈 1) while the corresponding pain scores were significantly higher for the area of the operated breast. Post-BMP iliac crest hematomas were encountered in 13 out of 58 patients (22.4%) who were significantly older (p = 0.04), less frequently smokers (p = 0.02), and presented with higher body mass index (p = 0.01) than controls. Within the area of BMP no signs of infection or sensibility disorders were observed. Comparison of patients with and without BMP did not show any significant difference in postoperative hospital stay duration. CONCLUSION: Referring to the potential clinical benefit of intraoperative BMP its prospectively assessed adverse side-effects appear relatively mild and thus acceptable.

    Abstract: Unhealthy dietary habits can increase the risk for serious medical conditions, such as cancer, yet the association between diet and breast cancer remains unclear. We investigated whether individual diets based on their inflammatory potential are associated with postmenopausal breast cancer risk by employing an energy-adjusted dietary inflammation index. In a German population-based case-control study, 2887 postmenopausal breast cancer patients (aged 50-74 years, first diagnosed between 2002 and 2005) and 5512 healthy age-matched controls provided information on dietary habits for the year prior to diagnosis (cases) or recruitment (controls) using a 176-items food frequency questionnaire. Associations between the energy-adjusted dietary inflammation index (E-DII) score (both as continuous variable and in quintiles) and risk for breast cancer were assessed using conditional logistic regression adjusted for potential confounders. No significant associations between the E-DII score and postmenopausal breast cancer risk were observed (adjusted OR Q5 vs Q1: 1.01, 95% CI: 0.86-1.17). Associations did not differ by estrogen receptor/progesterone receptor status (ER + PR+: adjusted OR Q5 vs Q1: 1.06, 95% CI: 0.88-1.27; ER + or PR+: OR Q5 vs Q1: 1,07, 95% CI: 0.79-1.45; ER-PR-: OR Q5 vs Q1: 0.87 95% CI: 0.63-1.20). Our results regarding E-DII are consistent with previous studies reporting a lack of association between C-reactive protein, a marker of systemic inflammation, and postmenopausal breast cancer risk. The findings may reflect a real absence of association between dietary inflammatory potential and postmenopausal cancer risk or an underestimation of association due to recall bias. Further investigation is warranted in cohort studies.
