The effect of information about the benefits and harms of mammography on women's decision-making: study protocol for a randomized controlled trial.

Background: The decision to participate or not in breast cancer screening is complex due to the trade-off between the expected benefit of breast cancer mortality reduction and the major harm of overdiagnosis. It seems ethically necessary to inform women so that they can actively participate in decision-making and make an informed choice based on their values and preferences. The objective of this study is to assess the effects of receiving information about the benefits and harms of screening on decision-making, in women approaching the age of invitation to mammography screening.

Towards the centralization of digestive oncologic surgery: changes in activity, techniques and outcome.

Aim: The objective of the present study was to examine changes in the activity, surgical techniques and results from the process of centralization of complex digestive oncologic surgery in 2005-2012 as compared to 1996-2000.

Material And Methods: A retrospective cohort study employing the minimum basic data set of hospital discharge (MBDSHD 1996-2012) from public centers in Catalonia (Spain) was performed. The population consisted of individuals aged > 18 who underwent digestive oncologic surgery (esophagus, pancreas, liver, stomach or rectum).

Cost-effectiveness and harm-benefit analyses of risk-based screening strategies for breast cancer.

The one-size-fits-all paradigm in organized screening of breast cancer is shifting towards a personalized approach. The present study has two objectives: 1) To perform an economic evaluation and to assess the harm-benefit ratios of screening strategies that vary in their intensity and interval ages based on breast cancer risk; and 2) To estimate the gain in terms of cost and harm reductions using risk-based screening with respect to the usual practice. We used a probabilistic model and input data from Spanish population registries and screening programs, as well as from clinical studies, to estimate the benefit, harm, and costs over time of 2,624 screening strategies, uniform or risk-based.

Cost-effectiveness of early detection of breast cancer in Catalonia (Spain).

Background: Breast cancer (BC) causes more deaths than any other cancer among women in Catalonia. Early detection has contributed to the observed decline in BC mortality. However, there is debate on the optimal screening strategy.

[Current state of breast cancer surgery in Andalusia and Catalonia].

Background: Surgery is an essential element of breast cancer treatment. The aim of this study was to describe the progress and current practice in oncological breast surgery in Catalonia and Andalusia.

Material And Method: An observational study was conducted, collecting data from the Minimum Basic Data Set at Hospital Discharge.

Effectiveness of early detection on breast cancer mortality reduction in Catalonia (Spain).

Background: At present, it is complicated to use screening trials to determine the optimal age intervals and periodicities of breast cancer early detection. Mathematical models are an alternative that has been widely used. The aim of this study was to estimate the effect of different breast cancer early detection strategies in Catalonia (Spain), in terms of breast cancer mortality reduction (MR) and years of life gained (YLG), using the stochastic models developed by Lee and Zelen (LZ).

[Planning highly specialised services in Catalonia].

One of the principal challenges in healthcare systems is deciding which services have to be concentrated, taking into account, among other things, their low-frequency, complexity, risk, accumulated experience and costs., Concentration must make it possible to guarantee the quality of the service and the best results possible. This article describes, the conceptual elements, the benchmark criteria, the impact on the centres and the minimum conditions that the mechanisms must meet, which have been taken into account in the reorganisation of high-complexity services in Catalonia.

Dissemination of periodic mammography and patterns of use, by birth cohort, in Catalonia (Spain).

Background: In Catalonia (Spain) breast cancer mortality has declined since the beginning of the 1990 s. The dissemination of early detection by mammography and the introduction of adjuvant treatments are among the possible causes of this decrease, and both were almost coincident in time. Thus, understanding how these procedures were incorporated into use in the general population and in women diagnosed with breast cancer is very important for assessing their contribution to the reduction in breast cancer mortality.

Competing risks to breast cancer mortality in Catalonia.

Background: Breast cancer mortality has experienced important changes over the last century. Breast cancer occurs in the presence of other competing risks which can influence breast cancer incidence and mortality trends. The aim of the present work is: 1) to assess the impact of breast cancer deaths among mortality from all causes in Catalonia (Spain), by age and birth cohort and 2) to estimate the risk of death from other causes than breast cancer, one of the inputs needed to model breast cancer mortality reduction due to screening or therapeutic interventions.
