Background: Cancer survivors are a heterogeneous group with complex health problems. Data concerning its total number and growing dynamics for Switzerland are scarce and outdated.Methods: Population and mortality data were retrieved from the Swiss Federal Statistical Office (FSO). Incidence and relative survival for invasive cancers were computed using data from the cancer registries Geneva (1970-2009), St. Gallen - Appenzell (1980-2010), Grisons & Glarus (1989-2010), and Valais (1989-2010). We estimated prevalence for 1990-2010 using the Prevalence, Incidence Approach MODel (PIAMOD) method. We calculated trends in prevalence estimates by Joinpoint analysis. Projections were extrapolated using the above models and based on time trends of the period 2007-2010.Results: The estimated number of cancer survivors increased from 139′717 in 1990 (2.08% of the population) to 289′797 persons in 2010 (3.70%). The growth rate shows an exponential shape and was 3.3% per year in the period 2008 to 2010. Almost half of the survivors have a history of breast, prostate or colorectal cancer. Among cancer survivors, 55% are women but the increases have been more marked in men (p < 0.01, 3.9% annual increase in men vs. 2.7% in women since 2008). By the end of 2020 372′000 cancer survivors are expected to live in Switzerland.Conclusions: There is a rapidly growing population of cancer survivors in Switzerland whose needs and concerns are largely unknown. © 2013 Herrmann et al.; licensee BioMed Central Ltd.

BACKGROUND: There is considerable heterogeneity in the use of chemotherapy in early breast cancer (BC), despite international recommendations issued from the NCCN, NIH and the St.Gallen bi-annual conference. METHODS: We included 1,535 patients from seven Swiss cancer registries between 2003 and 2005 receiving chemotherapy for stage I to III BC. Chemotherapy was categorised into (a) FAC/FEC, anthracyclines followed by CMF or anthracycline-taxane combinations (FAC-T) (781 patients) and (b) other chemotherapy regimens such as CMF/AC (EC) (754 patients). Predictors for choosing FAC-T over non-FAC-T chemotherapy were separately determined in all patients and in ER-negative patients (n = 496) by multivariate logistic regression analysis. RESULTS: The use of FAC-T increased significantly over time, from 44% in 2003 to 55% in 2005. BC stage III (versus stage I-II) and nodal positivity were the predominant predictors for using FAC-T chemotherapy in the adjusted model (odds ratio (OR) 4.1, 95%-confidence intervals (CI) 2.6-6.3 and OR 3.0, 95%-CI 2.0-4.4, respectively). In high-risk ER-negative BC patients, poor histological differentiation was more important to choose FAC-T chemotherapy (OR 3.8, 95%-CI 1.9-7.5) than tumour stage or nodal status. The use of FAC-T chemotherapy varied substantially among the seven geographic regions, from 20% in rural Grisons-Glarus to 73% in Zurich. CONCLUSIONS: Tumour biology is a predominant factor for choosing FAC-T over older chemotherapy regimens in patients with ER-negative early BC, but improvements should be made to reduce the substantial regional heterogeneity. Further epidemiological studies should assess how the use of FAC-T chemotherapy is affecting clinical outcome in patients with early BC and different risk profiles.

Objectives: The primary objective of this population-based study is to describe the patterns of care of elderly patients with breast cancer (BC), and evaluate potential causative factors for the decrease in BC-specific survival (BCSS) in the elderly. Patients and Methods: We included all or representative samples of patients with newly diagnosed BC from seven Swiss cancer registries between 2003 and 2005 (n=4820). Surgical and non-surgical BC treatment was analyzed over 5 age groups (<65, 65 to <70, 70 to <75, 75 to <80 and ≥80. years), and the predictive impact of patient age on specific treatments was calculated using multivariate logistic regression analysis. Results: The proportion of locally advanced, metastatic and incompletely staged BC increased with age. The odds ratio for performing breast-conserving surgery (BCS) in stages I-II BC (0.37), sentinel lymph node dissection (SLND) in patients with no palpable adenopathy (0.58), post-BCS radiotherapy (0.04) and adjuvant endocrine treatment (0.23) were all in disfavor of patients ≥80. years of age compared to their younger peers. Only 36% of patients ≥80. years of age with no palpable adenopathy underwent SLND. In the adjusted model, higher age was a significant risk factor for omitting post-BCS radiotherapy, SLND and adjuvant endocrine treatment. Conclusions: This study found an increase in incomplete diagnostic assessment, and a substantial underuse of BCS, post-BCS radiotherapy, SLND and adjuvant endocrine treatment. in elderly patients with BC. There is a need for improved management of early BC in the elderly even in a system with universal access to health care services. © 2012 Elsevier Ltd.

Background: In the past decades, mortality of female gender related cancers declined in Switzerland and other developed countries. Differences in the decrease and in spatial patterns within Switzerland have been reported according to urbanisation and language region, and remain controversial. We aimed to investigate geographical and temporal trends of breast, ovarian, cervical and uterine cancer mortality, assess whether differential trends exist and to provide updated results until 2011. Methods: Breast, ovarian, cervical and uterine cancer mortality and population data for Switzerland in the period 1969-2011 was retrieved from the Swiss Federal Statistical office (FSO). Cases were grouped into <55 year olds, 55-74 year olds and 75+ year olds. The geographical unit of analysis was the municipality. To explore age- specific spatio-temporal patterns we fitted Bayesian hierarchical spatio-temporal models on subgroup-specific death rates indirectly standardized by national references. We used linguistic region and degree of urbanisation as covariates. Results: Female cancer mortality continuously decreased in terms of rates in all age groups and cancer sites except for ovarian cancer in 75+ year olds, especially since 1990 onwards. Contrary to other reports, we found no systematic difference between language regions. Urbanisation as a proxy for access to and quality of medical services, education and health consciousness seemed to have no influence on cancer mortality with the exception of uterine and ovarian cancer in specific age groups. We observed no obvious spatial pattern of mortality common for all cancer sites. Rate reduction in cervical cancer was even stronger than for other cancer sites. Conclusions: Female gender related cancer mortality is continuously decreasing in Switzerland since 1990. Geographical differences are small, present on a regional or canton-overspanning level, and different for each cancer site and age group. No general significant association with cantonal or language region borders could be observed. © 2015 Herrmann et al.

Purpose: Regional disparities in breast cancer outcomes have been reported in Switzerland. The purpose of this study is to investigate geographic variation in early diagnosis and management of breast cancer. Methods: We used data from a representative sample of 4820 women diagnosed with invasive breast cancer between January 1, 2003 and December 31, 2005 identified by seven Swiss population based cancer registries. We collected retrospectively detailed information on mode of detection, tumor characteristics and treatments. Differences across geographic regions were tested for statistical significance using chi-square tests and uni- and multivariate logistic regression. Results: Considerable disparities in early detection and management of early breast cancer were found across regions. In particular, the proportion of early detected cancer varied from 43% in Valais to 27% in St. Gallen-Appenzell. Mastectomy rates varied from 24% in Geneva to 38% in St. Gallen-Appenzell and Grisons-Glarus. Higher reconstruction rates were observed in regions with lower rates of mastectomy. The use of sentinel node procedure in patients with nodal negative disease was high in Geneva and low in Eastern Switzerland. Differences in compliance with recommendations on the use of endocrine therapy and chemotherapy were less pronounced but statistically significant. Conclusions: This analysis shows considerable geographic variation in breast cancer care in a health system characterized by high expenditures, universal access to services and high decentralization. Further study into the causes and effects of this variation on short- and long term patient outcomes is needed. © 2010 Elsevier Ltd. All rights reserved.

Background: The aim of this study was to investigate predictors of state-of-the-art management of early breast cancer in Switzerland. Patients and methods: The study included 3499 women aged 25-79 years diagnosed with invasive breast cancer stages I-IIIA in 2003-2005. Patients were identified through population-based cancer registries and treated in all kinds of settings. Concordance with national and international recommendations was assessed for 10 items covering surgery, radiotherapy, systemic adjuvant therapy and histopathology reporting. We used multivariate logistic regression to identify independent predictors of high (10 points) and low (≤7 points) concordance. Results: In one-third of the patients, management met guidelines in all items, whereas in about one-fifth, three or more items did not comply. Treatment by a surgeon with caseload in the upper tercile and team involved in clinical research were independent predictors of a high score, whereas treatment by a surgeon with a caseload in the lower tercile was associated with a low score. Socioeconomic characteristics such as income and education were not independent predictors, but patient's place of residence and age independently predicted management according to recommendations. Conclusion: Specialization and involvement in clinical research seem to be key elements for enhancing the quality of early breast cancer management at population level. © The Author 2010.

Brain metastases from non-small cell lung cancer (NSCLC) are associated with a poor prognosis. In selected cases, surgical resection of brain metastases may be indicated, but the identification of patients suitable for surgery remains difficult. We collected data on patient and tumour characteristics known or suspected to be associated with survival by chart review. Data was merged with available data from the local cancer registry. We identified 64 NSCLC patients with resected brain metastases. Median overall survival after resection was 9.1 months with only two patients (3 %) surviving more than 71 and 80 months. One and 2-year survival were 42 and 12.5 %. Median survival for males and patients with more comorbidities was shorter (8 vs. 10 months [p = 0.11] and 6 vs. 9 months [p = 0.06]). Patients with squamous cell carcinomas (33 % of the patients) had a significantly worse survival than patients with other histologies (7 vs. 10 months [p = 0.02]) with no patient living longer than 2 years. Squamous cell histology was associated with worse prognosis after resection of brain metastases in patients with non-small cell lung cancer. Histology, among other parameters, may also be taken into account when choosing the appropriate patients for resection of brain metastases. © 2015, Springer Science+Business Media Dordrecht.
