AIMS: There is a lack of national and international publicly available long-term survival outcome data from individual healthcare providers in medical oncology. In this study, the overall survival at a medium-sized medical oncology service at Olten Cantonal Hospital was evaluated and compared as a local benchmark report with national data from the Swiss Cancer Registries. Furthermore, adherence to treatment guidelines was investigated as an additional quality indicator. METHODS: The 1- and 5-year overall survival of all patients with breast cancer, testicular cancer, colon cancer, non-small-cell lung cancer, Hodgkin lymphoma, and diffuse large B-cell lymphoma in Switzerland from 2008 to 2017 with at least one outpatient visit at the in-house medical oncology service at Olten Cantonal Hospital was analysed and compared with the specific overall population-based outcome data provided by the National Agency for Cancer Registration (NACR), which were set as a national benchmark. Until 2020, no data from the Canton of Solothurn, to which Olten belongs, were reported to the NACR. Further, adherence to internationally recognized clinical guidelines for stage-specific treatment was assessed. RESULTS: Until September 8, 2020, data on 842 patients with a median follow-up period of 70 months were collected and analysed. The 1- and 5-year overall survival for colon and non-small cell cancer, Hodgkin lymphoma, and diffuse large B-cell lymphoma and the 5-year overall survival for testicular cancer in the Olten cohort did not significantly differ from the NACR data. The 1-year overall survival for testicular cancer was not comparable statistically. The 5-year overall survival for breast cancer (unadjusted for stage) was significantly higher in the NACR collective (84.5%) than in the Olten collective (79.7%) but not for the individual breast cancer stages. The Olten collective included approximately 2.5 times as many patients with stage 4 breast cancer (17.5%) as the NACR collective (6.9%). Approximately 92.4% of the patients in the curative setting and 85.8% of the patients in the palliative setting received first-line treatment according to guidelines. CONCLUSIONS: The statistically comparable local 1- and 5-year overall survival of the analysed malignancies, with adjustment for stage for the 5-year overall survival for breast cancer, is in line with the national benchmark. Adherence to treatment guidelines is high.

BACKGROUND During the last 20 years, treatment for chronic lymphocytic leukaemia (CLL) / small lymphocytic lymphoma (SLL) has advanced, with improved clinical outcomes in randomised controlled trials. Currently, no data have been published from Switzerland to assess effectiveness of recent healthcare advances in CLL/SLL on a population-based level. We aimed to estimate trends in incidence, mortality and survival for patients with CLL/SLL in Switzerland. METHODS We retrospectively studied registry data from the National Agency for Cancer Registration (NACR) database in Switzerland from 1997 to 2016. We investigated incidence, mortality and survival in consecutive 5-year periods. Age-specific rates were calculated for three age groups (

BACKGROUND International guidelines state that bone-targeted agents such as denosumab or zoledronic acid at doses used for bone metastasis are not indicated for patients with metastatic castration-sensitive prostate cancer (mCSPC) with bone metastases. Whereas denosumab has never been studied in this patient population, zoledronic acid has been shown to be ineffective in decreasing the risk for skeletal-related events. This study estimates the prevalence and economic consequences of real-world use of bone-targeted agents for mCSPC patients in Switzerland. METHODS To estimate the frequency of bone-targeted agent administration and skeletal-related events, data from a non-interventional, cross-sectional survey involving oncologists across Switzerland (SAKK 95/16) was combined with data from the Swiss National Institute for Cancer Epidemiology and Registration (NICER). Economic parameters were calculated from the perspective of the healthcare system over the median time to prostate-specific antigen (PSA) progression for the extrapolated patient group, using data from NICER. The cost calculation covered costs for bone-targeted agents, their administration and skeletal-related events. The time to PSA progression (33.2 months), as well as the probability and cost of skeletal-related events were derived from the literature. RESULTS The survey was answered by 86 physicians treating 417 patients, of whom 106 (25.4%) had prostate cancer, with 36 (34.0%) of these mCSPC. The majority of mCSPC patients (52.8%, n = 19) received bone-targeted agents monthly. Denosumab was the treatment of choice in 84.2% of patients (n = 16). Extrapolation using data from NICER indicated that 568 mCSPC patients may be treated with bone-targeted agents at doses used for bone metastasis every year in Switzerland, leading to estimated total costs of more than CHF 8.3 million over 33.2 months. Because of its more frequent prescription and higher price, it appears that almost 93% of the total costs can be attributed to denosumab. For both denosumab and zoledronic acid, the most expensive components were the cost of administration and the drug cost, making up more than 90% of the total costs, with the rest being costs of skeletal-related events. CONCLUSIONS This study found that the administration of bone-targeted agents in doses used for bone-metastatic diseases to prevent skeletal-related events is frequent in the setting of mCSPC and results in significant costs for the healthcare system.

BACKGROUND Amenable mortality is a composite measure of deaths from conditions that might be avoided by timely and effective healthcare. It was developed as an indicator to study health care quality. METHODS We calculated mortality rates for the population aged 0–74 years for the time-period 1996–2010 and the following groups of causes of death: amenable conditions, ischaemic heart diseases (IHD, defined as partly amenable) and remaining conditions. We compared the Swiss results with those published for 16 other high-income countries. To examine the association between amenable mortality and socioeconomic position, we calculated hazard ratios (HRs) by using Cox regression. RESULTS Amenable mortality fell from 49.5 (95% confidence interval [CI] 48.2–51.0) to 35.7 (34.6–36.9) in males and from 55.0 (53.6–56.4) to 43.4 (42.2–44.6) per 100 000 person-years in females, when 1996–1998 was compared with 2008–2010. IHD mortality declined from 64.7 (95% CI 63.1–66.3) to 33.8 (32.8–34.8) in males and from 18.0 (17.2–18.7) to 8.5 (8.0–9.0) in females. However, between 1996–1998 and 2008–2010 the proportion of all-cause mortality attributed to amenable causes remained stable in both sexes (around 12% in males and 26% in females). Compared with 16 other high-income countries, Switzerland had the lowest rates of amenable mortality and ranked among the top five with the lowest ischaemic heart disease mortality. HRs of amenable causes in the lowest socioeconomic position quintile were 1.77 (95% CI 1.66–1.90) for males and 1.78 (1.47–2.16) for females compared with 1.62 (1.58–1.66) and 1.38 (1.33–1.43) for unamenable mortality. For ischaemic heart disease, HRs in the lowest socioeconomic position quintile were 1.76 (95% CI 1.66–1.87) for males and 2.33 (2.07–2.62) for females. CONCLUSIONS Amenable mortality declined substantially in Switzerland with comparably low death rates for amenable causes. Similar to previous international studies, these Swiss results showed substantial socioeconomic inequalities in amenable mortality. Proportions of amenable mortality remained constant over time and patterns of inequalities observed for amenable causes in men did not substantially differ from those observed for non-amenable causes of death. Additional amenable mortality research is needed to better understand the factors contributing to mortality changes and social inequalities including information on disease characteristics and health care supply measures.

QUESTION UNDER STUDY/PRINCIPLES: This study aimed to evaluate trends in the incidence of oesophageal and gastric cancer by anatomical location and histology using nationally representative Swiss data. METHODS: We included all oesophageal and gastric cancers recorded in 10 Swiss population-based cancer registries 1982–2011. We calculated age-standardised incidence rates (ASIRs) per 100 000 person-years (PY) (European standard) for both cancer sites stratified by sex, language region (German, French-Italian), morphology and anatomical location. To assess time trends, we estimated annual percentage changes (APCs) with 95% confidence intervals (95% CIs). RESULTS: ASIR of oesophageal adenocarcinoma increased in both sexes and language regions (p

QUESTION UNDER STUDY: What are the trends in avoidable cancer mortality in Switzerland and neighbouring countries? METHODS: Mortality data and population estimates 1996–2010 were obtained from the Swiss Federal Statistical Office for Switzerland and the World Health Organization Mortality Database (http://www.who.int/healthinfo/mortality_data/en/) for Austria, Germany, France and Italy. Age standardised mortality rates (ASMRs, European standard) per 100 000 person-years were calculated for the population
