Table 1 Objectives

1. Outcomes assessment

2. Creation of predictive models

3. Health services evaluation in breast cancer patients in Spain

To describe and analyse variability in outcomes by mode of detection, hospital, region and surgeon

• To create and validate predictive rules for relapse, mortality and complications

• To estimate the average costs of breast cancer care in Spain

To describe and analyse variability in the diagnostic process and treatment

• To identify risk factors for poor health-related quality of life 2 years after treatment

• To investigate differences between Spanish regions

To explore potential inequalities by age, education and socioeconomic level

• To validate our predictive rules for relapse, mortality and complications in a retrospective sample of patients from early detection programs

• To identify the most efficient process and treatments in breast cancer

To evaluate the impact of first hospital care (urgent or scheduled) and of delays on relapse, metastasis and death
