Show moreSince cancer survival rates are rising, there is growing attention for longterm side effects of cancer and its treatment. A common side effect is the negative impact of treatment on sexuality of patients and their partners. Patient and partners as well as healthcare professionals experience several barriers to discuss this topic, like lack of time and lack of knowlegde. Two-thirds of the cancer patients reported to be in need of information regarding sexual health; especially those who were younger, who reported a negative impact of cancer on sexuality and those who were diagnosed less than two years ago. Patients and partners reported to prefer to discuss sexual health with nurse practitioners throughout the treatment proces. Besides, satisfaction with sexual life after treatment is related to satisfaction before treatment, not only with current sexual function.Widely available information and defining responsibility within the oncology treatment team would be helpful to improve communication around sexual health in cancer care. Additionally, specialized clinics would tackle soms frequently reported barriers of discussing sexuality. More reseach is needed on the implementation of sexual healthcare in oncology practice to deliver continuum of care, which will ultimately improve patient care. Show less

Show moreThe aim of this work was to develop methods to measure structural changes in the skeleton using MicroCT. In addition, these new methods should be able to quantify biologically relevant changes. In order to do this, normalized methods to analyse MicroCT scans and perform quantitative measurements within these datasets are described in this thesis. These techniques were combined with a biological angiogenesis assay and used as research tools in a study comparing various different combination treatments of bone metastases. Show less

Show moreThe skeleton is one of the most common organs to be affected by metastatic disease. However, only a restricted number of solid cancers, especially those of the breast and prostate, are responsible for the majority of the bone metastases. Bone metastases are a major cause of morbidity, characterized by severe pain and high incidence of fractures, spinal cord compression and bone marrow aplasia requiring hospitalization. Despite the high frequency of skeletal metastases, the molecular mechanisms underlying the predisposition for tumors to colonize bone are poorly understood and treatment options are often unsatisfactory. The focus of this thesis was to better understand the processes that contribute to the formation of distant metastasis (chapter 2), particularly to bone (chapter 4__7), as well as to explore new treatment strategies with conventional (chapter 4 and 5) and novel therapeutic molecules (chapter 6 and 7) using optical imaging to sensitively monitor growth, dissemination and metastasis in mouse models (chapter 3__7).
