[Health services research in psycho-oncology].

Given the increasing incidence of cancer and improved diagnostics and cancer treatments, the number of cancer patients in industrialized nations is increasing worldwide. Multimodal treatment regimens, which contribute to a tumor-free survival or extend patients life expectancy can, however, alone or in combination increase the risk of physical and psychosocial long-term problems or late complications. For many patients cancer has become a chronic disease and is associated with significant physical and psychosocial problems that affect the quality of life in the medium and longer-term perspective. Common problems of cancer patients in the longer course of the disease include chronic and post-cancer pain, cancer-specific fatigue, psychosocial distress and impairment in self-management and activities of daily living, work participation and quality of life. Current developments with respect to both curative and palliative oncological care have various implications for health services research in psycho-oncology. These questions relate to issues of care needs, service provision and the appropriateness of care, issues of development, implementation and scientific evaluation of patient-centered and affordable support programs for different groups of cancer patients with different supportive care needs, issues of access and utilization of supportive care services, as well as questions of appropriate outcome criteria of health services research.
