To measure 3-year care costs of breast, prostate, colorectal and lung cancers disaggregated by site and clinical stage. A retrospective observational design was employed to investigate care costs of cases recorded in the Registry of the Basque Country between 2010 and 2015. Data gathered included TNM stage and demographic, clinical and resource use variables. Total costs per patient with stage IV disease were calculated by combining generalized linear models with parametric survival analysis. Unit costs were obtained from the analytical accounting system of the Basque Health Service. The sample comprised 23,782 cancer cases (7801 colorectal, 5530 breast, 4802 prostate and 5649 lung cancer). The mean 3-year costs per patient with stage I to III disease were €11,323, €13,727, €8,651 and €12,023 for colorectal, breast, prostate and lung cancer, respectively. The most important cost components were surgery and chemotherapy. Total survival-adjusted costs until death for patients with stage IV disease (€27,568, €26,296, €16,151 and €15,931 for breast, colorectal, lung and prostate cancer, respectively) were higher than the 3-year costs for those with earlier-stage disease. This study quantitatively shows the pattern of changes in the economic burden of cancer throughout its natural history and the great magnitude of this burden for the health system. The use of indicators based on real-world data from each regional health service would allow cancer care in each region to be tailored to local population needs. Determinar el coste del tratamiento de los cánceres de mama, próstata, colorrectal y pulmón según la localización y el estadio clínico. Se utilizó un diseño observacional retrospectivo con los casos del Registro de Euskadi entre 2010 y 2015. Los datos incluyeron el estadio TNM, variables demográficas y clínicas, y uso de recursos. Los costes totales por paciente en estadio IV se calcularon combinando modelos lineales generalizados con el análisis paramétrico de supervivencia. Los costes unitarios se obtuvieron del sistema de contabilidad analítica del Servicio Vasco de Salud. La muestra estuvo compuesta por 23.782 casos (7801 colorrectal, 5530 de mama, 4802 de próstata y 5649 de pulmón). Los costes medios por paciente a 3 años en estadio I a III fueron 11.323 €, 13.727 €, 8651 € y 12.023 € para los cánceres colorrectal, de mama, de próstata y de pulmón, respectivamente. Los costes para el estadio IV (27.568 €, 26.296 €, 16.151 € y 15.931 € para los cánceres
