Filter by:In various common cancers, the skeleton is a preferred site of metastasis. These bone metastases are the most common cause of cancer-related pain, which significantly impair quality of life. It is postulated that the clinical target volume (CTV) of painful bone metastases consists of cancer cells and tumor-associated host cells: the tumor-host ecosystem. Advances in biological imaging (positron emitting tomography PET) might allow us to selectively identify the tumor-host ecosystem within the anatomical boundaries of a bone metastasis. These findings suggest the potential of intentionally non-homogenous dose escalation (dose painting by numbers) to improve pain control. The hypothesis is that fluorodeoxyglucose positron emitting tomography (FDG-PET) can detect the intra-bone metastasis regions confined with tumor-associated host-cell compartments responsible for metastasis-related pain. The primary objective is to improve pain control with biological image-guided stereotactic body radiotherapy compared to conventional radiotherapy.
This trial will facilitate access to denosumab for adults with advanced cancer who have participated in a denosumab phase 3 study until denosumab is approved and available for sale.
Standard indications for palliative radiation of bony metastases include pain, spinal cord compression, and impending pathologic fractures. Palliative radiation therapy serves to reduce pain, improve quality of life, and avoid complications. Tailored training of the paravertebral musculature may support radiation therapy and improve above named factors. DISPO was designed to investigate the impact of tailored physical exercise in patients with vertebral metastases as compared to manual therapy (massage etc.). The trial includes patients with painful bony metastases, patients with spinal cord compression or impending pathological fractures are excluded. The investigations are carried out in a prospective randomized controlled phase-II parallel group design.
Prostate and breast cancer continues to be the most common cancer among men and women, respectively. The exact assessment of the cancer spread with detection of possible bone metastasis is crucial for treatment decision. In the current study 50 patients with prostate cancer and 50 patients with breast cancer at high risk for bone metastases or with know metastatic disease will be studied with multiple imaging modalities. Patients will be recruited from the Department of Oncology, Turku University Hospital. Planar bone scintigraphy (BS), single photon emission computed tomography combined with low-dose computed tomography (SPECT/CT), 18F-fluoride positron emission tomography computed tomography (PET/CT) and magnetic resonance imaging (MRI) will be performed to all patients. The primary objective is to determine the diagnostic accuracy of the four imaging modalities. The secondary goal is to calculate the sensitivities and specificities of the four imaging modalities on a patient-to-patient and lesion-to-lesion basis. Based on the results of this study an optimal imaging protocol for detection of prostate and breast cancer bone metastasis will be developed and validated.
This pilot trial studies the differentiation of bone sarcomas and osteomyelitis with ferumoxytol-enhanced magnetic resonance imaging (MRI). Imaging procedures that allow doctors to more accurately differentiate between malignant bone sarcomas and osteomyelitis may help in diagnosing patients correctly and may result in more timely treatment.
This is a randomized clinical trial that will be carried out to examine the use of bioactive glass granules (S53P4) as bone graft substitute in filling small and large bone defects as compared with autogenous and allogeneic bone grafting, respectively.
The purpose of this study is to compare 18F-Fluoride PET bone scans to traditional 99mTc-MDP bone scan to determine if one is better for diagnosing bone metastases.
This research is being done because is is not known if dexamethasone can prevent pain flare (their pain temporarily gets worse before it gets better) caused by the radiation used to treat painful bone metastases. Using dexamethasone to prevent pain like this has been studied in a few people and seems promising, but it is not clear if it can decrease the pain or prevent the pain flare before it happens.
Bone is the most common site of distant breast cancer recurrence, and 65-75% of women with advanced breast cancer will develop bone metastases during the course of their disease. The most pressing problem in management of bony metastases today, is the inability to reliably identify patients at high risk for skeletal related events (SREs) (such as bone fractures, surgery/radiotherapy for pain or prevention of fractures, high calcium levels, and spinal cord compression) despite the standard use of bone medication (bisphosphonates). Using the latest innovations both in imaging and blood tests, this novel pilot project will develop a risk model for predicting bone metastases, which will be able to identify patients who would most benefit from novel treatments, such as the multikinase inhibitor Zactima and the Src inhibitor, AZD0530. Given that approximately 1/3 of patients with metastatic breast cancer and bony disease will sustain an SRE despite use of a bisphosphonate, there is an urgent unmet need in this large population to introduce effective bone protective agents.
This study will evaluate zoledronic acid's anti-cancer effects and Circulating Tumor Cell (CTCs) measurements in patients with HER2-negative metastatic breast cancer without bone metastasis.
