Background: The project conducted at the Tumour Centre in Regensburg aims to integrate quality of life (QL) diagnostics with the therapy of breast cancer patients and to evaluate the efficacy of QL diagnostics in the context of a randomized clinical trial.
Methods: The Regensburg Tumour Centre provides the infrastructure of the present project (telemedicine, project groups, quality circle). The treatment of breast cancer patients is based on the recent national breast cancer therapy guideline, including assorted QL-enhancing therapy options such as pain therapy, physiotherapy and lymphatic drainage, psychotherapy, social counselling and rehabilitation, nutrition and sports. During an implementation phase a new method of QL diagnostics has been developed. Five experts with varying professional background use the individual patient's QL profile and clinical and socio-demographic information in order to generate a QL report including a treatment recommendation. The study is designed as a two- arm randomized clinical trial with one test group (communication of the QL findings to the co-ordinating physician) and a control group (no communication). Patients with newly diagnosed breast cancer who are treated in the study region by one of the co-ordinating doctors will be included in this randomized study. At designated points in time QL assessments (EORTC QLQ-C30 plus BR23) will be conducted over a 12-months period.
Expected results: We expect that patients in the test group will experience a lower amount of QL deficits at the end of the study period (M = 1, SD = 2) than patients in the control group (M = 2, SD = 2). The statistical confirmation of this expected effect requires a total sample size of N = 200 (n = 100 vs. n = 100, alpha = 5% [two-tailed], beta = 10%).
Conclusions: This is the first study to evaluate a new form of QL diagnostics in the complexity of a real patient care environment, and it promises to make the inclusion of the quality of life concept into the current breast cancer treatment guideline more tangible.
