Background: Baseline quality of life (bQL) has been shown to be a predictor of the clinical outcome of oncological patients. The primary objective of the present study was to examine the role of bQL as a treatment predictor in oncological patients.
Methods: In this prospective study, all-stage cancer patients registered in the Network Oncology registry were enrolled, and their bQL at diagnosis was evaluated.
Results: Five hundred and thirty-eight oncological patients were eligible (median age 64 years). We show that survival-predicting bQL variables such as pain, low physical functioning or financial burden at tumor diagnosis were linked to lower systemic treatment (p = 0.03), reduced surgery (p = 0.007) or reduced oncological treatment compliance (0.01), respectively. Lastly, female gender and older cancer patients exhibited a tempered bQL.
Conclusion: Our study is one of the first to reveal that bQL at tumor diagnosis is significantly associated with the prediction of oncological treatment with distinctive age- and gender-related patterns. Our results emphasize the need to address the physical, psychosocial, and financial burden of cancer patients prior to their oncological treatment with respect to age and gender. The associations found here pave the way for early integration of patient-reported outcomes into oncological supportive concepts.
