Prospective non-interventional double trial regarding tumor-about fatigue syndrome during taxane therapy - Version FaTa-D(ocetaxel) - FaTa-D

Background: Tumor patients often suffer from symptoms of fatigue, which can be tumor- or therapy-related and is manifested by extreme fatigue and exhaustion that often persists for a long time beyond the therapy, immensely limiting the quality of life as well as the physical, psychological and cognitive performance of the patients and being emotionally very stressful for the affected persons and their families. Results: This was a non-interventional prospective observational single-arm cohort study of treatment with docetaxel LIV Pharma with parallel patient survey (DRKS-ID: DRKS00007954). During the documentation period, which lasted up to two years depending on the therapy regimen, parameters regarding the underlying oncological disease and its therapy were collected at regular intervals. At the same time, patients were asked about fatigue symptoms (Fatigue Scale MFI 20), quality of life (EORTC QLQ-C30) and their physical activity (BSA questionnaire according to Fuchs), as there are correlations between these "Patient Reported Outcomes". 90 patients were included in the study. Due to non-compliance with inclusion and exclusion criteria, death, loss of contact, and failure to initiate documentation, 38 of these patients dropped out of the population. Additional documentation could not be used for analysis because of missing patient questionnaires and incomplete documentation. Conclusion: An evaluation of the study is statistically not possible due to the small number of evaluable documentations. The incomplete response of the patient questionnaires can mainly be attributed to a lack of compliance, which can hardly be counteracted in a non-interventional study. It seems reasonable to investigate the tumor-associated fatigue syndrome within a registry study in order to reach the statistically necessary number of cases.
