Background: The publication of the Women's Health Initiative Study  in 2002 and the Million Women Study  in 2003 on the association of menopausal hormone therapy (HT) and breast cancer were followed by a decrease in the prescription of HT to menopausal women in western countries. In the following years several papers from different countries reported declines in breast cancer incidence and discuss whether this decline is related to the decreased use of menopausal hormone therapy. Methods: We contribute further data by analysing breast cancer incidence rates from the Hamburg Cancer Registry, Germany, for the time period 1991-2006 and HT use data from a large case-control study conducted in the Hamburg region. At first we determined whether there is a decline in breast cancer incidence in 2002/2003. To find supporting evidence for a causal relationship between breast cancer incidence and use of menopausal hormones we addressed the following issues: The decline in incidence should be more pronounced in the age groups, in which HT is used predominantly, i.e. age group 50-69. The decline in incidence should be most pronounced for breast cancer types more strongly associated with HT, i.e. invasive lobular cancer. Results: We observed a statistical significant decline in incidence of all invasive breast cancer in 2002/2003 in Hamburg. The increase in breast cancer incidence as well as the decline was most pronounced in the age group 50-69. Regarding the histological types of tumours in this age group the decline was only pronounced for invasive lobular cancer. The estimated prevalence of HT indicates a decreasing hormone use starting in 2001/2002. We found a strong decrease in prescriptions for menopausal hormone therapy between 2002 and 2005. Conclusion: In summary, our data add to the evidence of a relation between breast cancer incidence and menopausal hormone use. © 2010 Elsevier Ltd. Source

Background: Cancer survival is a key measure of the effectiveness of health-care systems. EUROCARE-the largest cooperative study of population-based cancer survival in Europe-has shown persistent differences between countries for cancer survival, although in general, cancer survival is improving. Major changes in cancer diagnosis, treatment, and rehabilitation occurred in the early 2000s. EUROCARE-5 assesses their effect on cancer survival in 29 European countries. Methods: In this retrospective observational study, we analysed data from 107 cancer registries for more than 10 million patients with cancer diagnosed up to 2007 and followed up to 2008. Uniform quality control procedures were applied to all datasets. For patients diagnosed 2000-07, we calculated 5-year relative survival for 46 cancers weighted by age and country. We also calculated country-specific and age-specific survival for ten common cancers, together with survival differences between time periods (for 1999-2001, 2002-04, and 2005-07). Findings: 5-year relative survival generally increased steadily over time for all European regions. The largest increases from 1999-2001 to 2005-07 were for prostate cancer (73·4% [95% CI 72·9-73·9] vs 81·7% [81·3-82·1]), non-Hodgkin lymphoma (53·8% [53·3-54·4] vs 60·4% [60·0-60·9]), and rectal cancer (52·1% [51·6-52·6] vs 57·6% [57·1-58·1]). Survival in eastern Europe was generally low and below the European mean, particularly for cancers with good or intermediate prognosis. Survival was highest for northern, central, and southern Europe. Survival in the UK and Ireland was intermediate for rectal cancer, breast cancer, prostate cancer, skin melanoma, and non-Hodgkin lymphoma, but low for kidney, stomach, ovarian, colon, and lung cancers. Survival for lung cancer in the UK and Ireland was much lower than for other regions for all periods, although results for lung cancer in some regions (central and eastern Europe) might be affected by overestimation. Survival usually decreased with age, although to different degrees depending on region and cancer type. Interpretation: The major advances in cancer management that occurred up to 2007 seem to have resulted in improved survival in Europe. Likely explanations of differences in survival between countries include: differences in stage at diagnosis and accessibility to good care, different diagnostic intensity and screening approaches, and differences in cancer biology. Variations in socioeconomic, lifestyle, and general health between populations might also have a role. Further studies are needed to fully interpret these findings and how to remedy disparities.

Background Fear of recurrence (FoR) is a widespread problem among breast cancer survivors. So far, little is known about prevalence, determinants, and consequences of FoR specifically in long-term breast cancer survivors, even though it was found to be one of the most important concerns in this group. Methods Analyses are based on data of several population-based cohorts of long-term breast cancer survivors, recruited by six German cancer registries. Overall, 2671 women were included in the analyses. FoR was assessed using the short form of the Fear of Progression Questionnaire. Potential determinants of moderate/high FoR and the association with depression and quality of life (QoL) were explored via multiple logistic and linear regression. Results Even though the majority of women reported low levels of FoR (82%), a substantial percentage experienced moderate (11%) and high (6%) FoR. Younger age (odds ratio=3.00, confidence intervals=1.91-4.73 for women below age 55years) and considering oneself as a tumor patient (odds ratio=3.36, confidence intervals=2.66-4.25) were found to exhibit the strongest associations with moderate/high FoR. Overall, psychosocial and sociodemographic factors played a far bigger role in FoR than clinical factors. Higher FoR was associated with higher depression and lower QoL. Conclusion Fear of recurrence (mostly low levels) is highly prevalent among long-term breast cancer survivors and can negatively affect QoL and well-being. Therefore, it should be given appropriate consideration in research and clinical practice. As specifically younger women tended to be impacted by FoR, it is crucial to be particularly attentive to specific needs of younger survivors. Copyright © 2013 John Wiley & Sons, Ltd.

Objectives: Male breast cancer is a rare disease of largely unknown aetiology. In addition to genetic and hormone-related risk factors, a large number of environmental chemicals are suspected of playing a role in breast cancer. The identification of occupations or occupational exposures associated with an increased incidence of breast cancer in men may help to identify mammary carcinogens in the environment. Methods: Occupational risk factors for male breast cancer were investigated in a multi-centre case-control study conducted in eight European countries which included 104 cases and 1901 controls. Lifetime work history was obtained during in-person interviews. Occupational exposures to endocrine disrupting chemicals (alkylphenolic compounds, phthalates, polychlorinated biphenyls and dioxins) were assessed on a case-by-case basis using expert judgement. Results: Male breast cancer incidence was particularly increased in motor vehicle mechanics (OR 2.1, 95% CI 1.0 to 4.4) with a dose-effect relationship with duration of employment. It was also increased in paper makers and painters, forestry and logging workers, health and social workers, and furniture manufacture workers. The OR for exposure to alkylphenolic compounds above the median was 3.8 (95% CI 1.5 to 9.5). This association persisted after adjustment for occupational exposures to other environmental oestrogens. Conclusion: These findings suggest that some environmental chemicals are possible mammary carcinogens. Petrol, organic petroleum solvents or polycyclic aromatic hydrocarbons are suspect because of the consistent elevated risk of male breast cancer observed in motor vehicle mechanics. Endocrine disruptors such as alkylphenolic compounds may play a role in breast cancer. Source

Introduction. The advent of tyrosine kinase inhibitors has produced 5-year survival of 90 + % for chronic myelocytic leukemia (CML) patients in clinical trials. However, population level survival has been lower, especially in older patients. Here, we examine survival of patients with CML in Germany and compare it to survival of patients in the United States (US). Methods. Data were extracted from the Surveillance, Epidemiology, and End Results database in the US and 11 cancer registries in Germany. Patients 15-69 years old diagnosed with CML were included in the analysis. Period analysis for 2002-2006 was used to provide the most up-to-date possible estimates of five-year relative survival. Results: Five-year relative survival was 68.7% overall in Germany and 72.7% in the US. Survival was higher in the US for all age groups except for ages 15-39 years, but the difference was only statistically significant for ages 50-59 years (at 67.5% vs 77.7% in Germany and the US, respectively). Survival decreased with age, ranging from 83.1% and 81.9%, respectively, in Germany and the US for patients 15-39 years old to 54.2% and 54.5%, respectively, in patients 65-69 years old. Survival increased between 2002 and 2006 by 12.0% points in Germany and 17.1% points in the US. Conclusions: Five-year survival estimates were higher in the US than in Germany overall, but the difference was only significant for ages 50-59 years. Survival did not equal that seen in clinical trials for either country, but strong improvement in survival was seen between 2002 and 2006. © 2013 Pulte et al.; licensee BioMed Central Ltd. Source
