Differences in Breast Cancer Characteristics by Mammography Screening Participation or Non-Participation.

BACKGROUND: The goal of the German Mammography Screening Program (MSP) is to enable the early detection and less intensive treatment of breast cancer. We compared tumor characteristics and prognostic markers in breast cancers that were detected by screening in the MSP, in the interval after a negative screening, or among non-participants in screening. METHODS: This retrospective series includes all of the 1531 cases of invasive and in situ breast cancer (DCIS, ductal carcinoma in situ) that were newly diagnosed in two certified breast care centers in Münster in the period 2006-2012 among women in the MSP target population. Complete information on the tumor characteristics, tumor biology, and primary surgical treatment were available for all cases. The mode of cancer detection was determined from the state cancer registry of North Rhine-Westphalia. Due to the retrospective design of this case series, there was no randomized allocation. RESULTS: The 874 cases of breast cancer among MSP participants (714 detected by screening, 160 in the interval after a negative screen) and the 657 cases among non-participants arose in women of similar age (mean, 60.2 versus 59.3 years). MSP participants with breast cancer had DCIS more commonly than non-participants did (23% versus 13%); invasive carcinomas were smaller (74% versus 55% in the T1 stage), less commonly node-positive (25% versus 31%), less commonly high-grade (19% versus 27%), and less commonly triple-negative (7% versus 12%); MSP participants received neoadjuvant treatment less frequently (2% versus 8%) and more frequently underwent breast-conserving surgery (75% versus 62%). They less commonly had a guideline-based indication for adjuvant chemotherapy (46% versus 52%). CONCLUSION: MSP participants with invasive breast cancer can generally be treated with less intensive surgical and systemic therapy than non-participants, even if interval cancers are also taken into account. Future studies should also investigate quality of life after a diagnosis of invasive carcinoma in screening participants.

Effects of short- and long-term variations in RLS severity on perceived health status - the COR-study.

In a cohort study among 2751 members (71.5% females) of the German and Swiss RLS patient organizations changes in restless legs syndrome (RLS) severity over time was assessed and the impact on quality of life, sleep quality and depressive symptoms was analysed. A standard set of scales (RLS severity scale IRLS, SF-36, Pittsburgh Sleep Quality Index and the Centre for Epidemiologic Studies Depression Scale) in mailed questionnaires was repeatedly used to assess RLS severity and health status over time and a 7-day diary once to assess short-term variations. A clinically relevant change of the RLS severity was defined by a change of at least 5 points on the IRLS scale. During 36 months follow-up minimal improvement of RLS severity between assessments was observed. Men consistently reported higher severity scores. RLS severity increased with age reaching a plateau in the age group 45-54 years. During 3 years 60.2% of the participants had no relevant (±5 points) change in RLS severity. RLS worsening was significantly related to an increase in depressive symptoms and a decrease in sleep quality and quality of life. The short-term variation showed distinctive circadian patterns with rhythm magnitudes strongly related to RLS severity. The majority of participants had a stable course of severe RLS over three years. An increase in RLS severity was accompanied by a small to moderate negative, a decrease by a small positive influence on quality of life, depressive symptoms and sleep quality.

Genome-wide association study identifies novel restless legs syndrome susceptibility loci on 2p14 and 16q12.1.

Restless legs syndrome (RLS) is a sensorimotor disorder with an age-dependent prevalence of up to 10% in the general population above 65 years of age. Affected individuals suffer from uncomfortable sensations and an urge to move in the lower limbs that occurs mainly in resting situations during the evening or at night. Moving the legs or walking leads to an improvement of symptoms. Concomitantly, patients report sleep disturbances with consequences such as reduced daytime functioning. We conducted a genome-wide association study (GWA) for RLS in 922 cases and 1,526 controls (using 301,406 SNPs) followed by a replication of 76 candidate SNPs in 3,935 cases and 5,754 controls, all of European ancestry. Herein, we identified six RLS susceptibility loci of genome-wide significance, two of them novel: an intergenic region on chromosome 2p14 (rs6747972, P = 9.03 × 10(-11), OR = 1.23) and a locus on 16q12.1 (rs3104767, P = 9.4 × 10(-19), OR = 1.35) in a linkage disequilibrium block of 140 kb containing the 5'-end of TOX3 and the adjacent non-coding RNA BC034767.

Inflammatory markers in age-related maculopathy: cross-sectional analysis from the Muenster Aging and Retina Study.

OBJECTIVE: To evaluate recent reports indicating that plasma levels of fibrinogen and high-sensitivity C-reactive protein (CRP) are associated with age-related maculopathy (ARM). METHODS: From the baseline examinations of the Muenster Aging and Retina Study, a cohort of 1060 subjects aged 59 to 82 years was assembled. Of these, 873 persons (82%) with bilateral gradable fundus photographs and complete data on fibrinogen, CRP, and potential confounders were included in a cross-sectional analysis. The main outcome measure was the association among fibrinogen, CRP, and ARM as assessed by multivariate logistic regression analysis. RESULTS: Fibrinogen and CRP levels were higher among participants with early and late ARM than among those without ARM. The crude odds ratios for ARM between the highest vs the lowest quartile were 1.90 (95% confidence interval [CI], 1.29-2.80) for fibrinogen and 1.43 (95% CI, 0.97-2.10) for CRP. After adjustment for cardiovascular risk factors, these odds ratios were 1.37 for fibrinogen (95% CI, 0.91-2.06) and 1.12 (95% CI, 0.73-1.73) for CRP. CONCLUSIONS: After adjustment for cardiovascular risk factors, we found no statistically significant association between fibrogen, CRP, and ARM. Therefore, our results do not indicate a role of systemic inflammation in ARM beyond what is already present owing to concurrent cardiovascular disease.

Serum levels of macular carotenoids in relation to age-related maculopathy: the Muenster Aging and Retina Study (MARS).

BACKGROUND: It has been hypothesized that the macular carotenoids, lutein and zeaxanthin, may protect against age-related maculopathy. We evaluated the association between blood concentrations of lutein (L) and zeaxanthin (Z) and age-related maculopathy (ARM) in a case-control analysis of the baseline examination of the Muenster Ageing and Retina Study (MARS). METHODS: Of the 1060 participants aged 59-82 years at baseline, 910 (85.9%) with bilateral gradable fundus photographs and complete data for the carotenoids and potential confounders were included. The Rotterdam classification system was used for definition of ARM stages. Multivariate linear regression methods were applied to model the relationship between macular carotenoids and the presence of ARM. RESULTS: The participants' mean age was 70.9+5.5 years, 59.9% were female, 20.8% had a normal bilateral fundus, and 48.5% showed signs of early ARM (uni- or bilateral) and 30.7% of late ARM (in at least one eye). In study participants with L and/or Z supplementation (15.6%), the median serum levels for L (Z) were approximately 2 times (1.5 times) higher than in subjects with no supplementation. After exclusion of subjects with L and/or Z supplementation, no statistically significant bivariate relationship was observed between the serum levels of L or Z and the presence of ARM. Multivariate regression models, adjusting for age, gender, smoking, body-mass index, and HDL-cholesterol blood levels, produced adjusted mean serum levels of 0.124, 0.112, and 0.131 microg/ml for L and 0.019, 0.020, and 0.022 microg/ml for Z in subjects with normal fundus, early ARM, and late ARM, respectively. CONCLUSION: In this large study, the serum concentrations of L and Z were not related to the prevalence of ARM. However, the large proportion of study participants taking L and/or Z supplementation may have affected these results.
