During the study three questionnaires must repeatedly be completed in by the patients: the BDI (PC) a depression scale, the EORTC-QLQ a quality of life assessment and the CIS20r, a fatigue scale and patients must fill in their medication on a list.
When cure is not longer possible, cancer patients enter the palliative phase. For many types of cancer several treatment options are available. The goal of this treatment is to prolong survival, but maintenance or even improvement of quality of life is of equal importance. The currently available systemic treatment options consist of conventional cytotoxic therapy, hormonal therapy, immunotherapy and the so-called targeted therapies. Combinations of these therapies are also being used. Targeted therapy concerns the application of a new class of drugs that are specifically directed against one or more well-defined molecular targets that are relevant for carcinogenesis, cell cycle regulation, tumour progression, metastasis, tumour angiogenesis and/or apoptosis. Today, the most successful drugs in this class are directed against the vascular endothelial growth factor (VEGF) and the epidermal growth factor receptor (EGFR). There is an explosive development ongoing in this field and many new drugs become available that have new targets or inhibit a combinations of targets. Meanwhile, targeted therapy has shown efficacy in many types of cancer and is registered for several indications.
The toxicity profile of targeted therapies is still largely unknown, and the aetiology of many known side effects has not been clarified. This implies that the effective treatment of side effects is in an early phase of development. Given the impact of side effects on the quality of life of a patient, increased knowledge on this topic is urgently required. Currently only a few systematic studies are available that address this issue. At the moment, three targeted therapies that are directed against VEGF are registered and used in the Netherlands: Sunitinib (Sutent®) and Sorafenib (Nexavar ®) both oral drugs and Bevacizumab (Avastin®), an intravenously drug.
In this study we will focus on fatigue, quality of life and depression in patients with metastatic cancer, treated with Sunitinib and Sorafenib. Fatigue is one of the most frequent side effects of targeted therapy that are directed against VEGF and that can have a huge influence on the quality of life. The incidence of fatigue in patients using Sunitinib in phase I studies was 70% and the fatigue was often dose limiting. (1-4) In phase II-III studies the incidence was 27% - 51%. 5,6 In a phase III randomized, double-blind placebo-controlled trial of Sorafenib the incidence of fatigue in the Sorafenib group was 37% and in the placebo group 28%. (7) It is possible that fatigue is a symptom of depression or anxiety, alternatively, prolonged fatigue in itself can lead to depression or anxiety.8 There has been found a significant and positive correlation between anxiety and depressive symptoms and fatigue after treatment for cancer.
