Organization of the cancer network in SUS: evolution of the care model.

In the current context of epidemiological transition, demographic changes, changes in consumption and lifestyle habits, and pressure on care costs and organized health systems for acute conditions, the Integrated Care Model by Shortell has become a conceptual reference in the search for new methods to manage chronic conditions by focusing on the health conditions of a given population that must be addressed by a set of institutions organized into networks. Within the last 15 years, cancer has gone from the third- to the second-leading cause of death in the State of São Paulo and has shown a gradual increase in the number of new cases; it has thus become a relevant issue for public health and health management. The model adopted by the State for the organization of the cancer care network was the motivation for this study, which aimed to evaluate the evolution of the model of care for cancer patients within the Unified Health System (Sistema Único de Saúde) based on the integrated care model. Since 1993, the year that cancer was first considered highly complex in the Sistema Único de Saúde by the Ministry of Health, it has been possible to observe a progressive orientation towards the integral and integrated care of patients with cancer. In the State of São Paulo, the active participation of qualified service providers through a Technical Reference Committee showed that experts could contribute to the definition of public policies, thereby providing a technical base for decision making and contributing to the development of clinical management.
