Active clinical trials for "Neoplasm Metastasis"

This study will evaluate treatment with High Intensity Focused Ultrasound (HIFU)in combination with ThermoDox (liposomal doxorubicin) is safe and effective in reducing pain for patients with painful bone metastases.

Patients presenting with multiple innumerable liver metastases will probably never come to resection, however, for all others, including patients with numerous multiple metastases or large metastases, resection should be considered after limited chemotherapy. There is consensus for a backbone chemotherapy consisting of fluoropyrimidine + oxaliplatin. FOLFOX was used in the previous EORTC study and is again recommended. The addition of targeted agents to standard chemotherapy in the perioperative strategy for mCRC might increase the ORR and R0 resectability, without significant increase in toxicity, therefore translating to a better outcome. BOS2 (EORTC 40091) was designed to test this hypothesis in patients with a KRAS wold-type profile. It was decided in parallel to design an open label, randomized, multi-center, 2-arm phase II-III study this time aimed at enrolling KRAS mutated patients. Arm A: (standard) mFOLFOX6 + Surgery Arm B: (experimental) mFOLFOX6 + Aflibercept + Surgery

This study is a clinical feasibility trial that will contribute to the clarification of whether sentinel node mapping with indocyanine green (ICG) provides a better basis for staging of colorectal cancer.

By applying short electric pulses to cells, the cell membranes can become permeabilised (electroporation). This can be used augment the effect of chemotherapy, by providing direct access to the cell cytosol. For the drug bleomycin, the enhancement of effect is several hundred fold, enabling once-only treatment. The investigators wish compare electrochemotherapy with radiotherapy when treating ulcerated cutaneous metastases up to 5 cm in diameter from any kind of histology.

Bevacizumab, an anti-angiogenic agent, plus fluorouracil based chemotherapy is considered a new standard for the treatment of metastatic colorectal cancer. Contrast-enhanced ultrasound with gas-encapsulated microbubbles can be used to assess tumour vascularity, particularly hepatic metastases, and may become a useful tool for monitoring anti-angiogenic therapies. The aim of this prospective, multicenter, non-randomized study is to evaluate the usefulness of hepatic contrast-enhanced ultrasound to predict response to bevacizumab based chemotherapy in patient with metastatic colorectal cancer. The primary objective of this study is to compare the functional vascular changes related to bevacizumab based chemotherapy and evaluated by hepatic contrast-enhanced ultrasound with classic RECIST criteria. The secondary objectives are to do a characterization of the pharmacokinetic of bevacizumab, to explore the pharmacodynamic effects of bevacizumab on functional vascular changes of hepatic metastases evaluated by hepatic contrast-enhanced ultrasound and to analyze the possible relationships between treatment efficacy or toxicity and constitutional gene polymorphisms linked to the bevacizumab.

This single arm study will assess the efficacy of loading doses of intravenous Bondronat in reducing pain in patients with breast cancer and metastatic bone disease experiencing moderate to severe bone pain. Patients will receive an intravenous infusion of 6mg Bondronat on days 1, 2 and 3. The anticipated time on study treatment is <3 months, and the target sample size is <100 individuals.

Panitumumab is a monoclonal antibody. It works by attaching to a protein called epidermal growth factor receptor found on normal and cancer cells. When panitumumab attaches, it blocks another protein called epidermal growth factor (EGF) from attaching to the cell. This is important because, when EGF is blocked, a cell's growth slows down or stops. Panitumumab may also help radiation therapy work. Also because panitumumab is a fully-human antibody, it may be less toxic than other monoclonal antibodies made to block the EGF receptor. Chemotherapy, such as capecitabine and oxaliplatin, works to kill cancer cells directly. Capecitabine given during radiation helps radiation therapy work better. This study is being done to learn how rectal cancer tumors that are not removed surgically respond to treatment with panitumumab and chemotherapy given before radiation therapy begins followed by treatment with panitumumab and capecitabine given with radiation therapy.

The purpose of this research is to study the effects and safety of Sensipar approved by the Food and Drug Administration (FDA) in patients with kidney failure who are being treated with dialysis and have uncontrolled secondary hyperparathyroidism (HPT).

The purpose of this study is to determine if a reduction in the enzyme 1-hydroxylase, which activates Vitamin D, is the cause of overactivity of the parathyroid glands (called secondary hyperparathyroidism - normal blood calcium and elevated parathyroid hormone) in a selected group of young patients with normal kidney function.

Almost 50 % of papillary thyroid cancer (PTC) patients have central lymph node metastases (CLNM), which are associated with a high risk of persistent or recurrent disease. However, the practice of performing a prophylactic central lymph node dissection (PCLND) routinely remains controversial. The proponents argue that without a PCLND, PTC patients with positive lymph nodes have an increased risk of local recurrence, and postponed node dissection leads to with 5-6 fold higher risk of morbidity. If performed, PCLND in clinical node negative patients increases staging to pN1 in more than 50% of the cases without increasing survival. The complication rate in PCLND is lower when compared to a technically challenging re-exploration in recurrent disease, with reported incidences of 0.6% and 7.3-20%, respectively. Opponents of routine PCLND point out the lack of randomized clinical trials and object to treatment-induced hypo-parathyroidism and recurrent nerve damage for the N0 patients. Currently, no diagnostic tool is available which reliably identifies these patient categories. Therefore, there is a clear need for novel diagnostic imaging modalities that overcome this issue. Molecular Fluorescence Guided Surgery (MFGS) is potentially such a diagnostic tool. The administration of NIR fluorescent tracers can increase detection accuracy of cancer and nodal metastatic tissue using macroscopic MFGS. Therefore, we aimed to identify a GMP-produced near infrared (NIR) tracer that potentially has a high target-to-background ratio in PTC compared to normal thyroid tissue. Tyrosine-protein kinase Met (c-Met) is significantly upregulated at the protein level in PTC compared to normal thyroid tissue. The investigators therefore hypothesize that the GMP-produced NIR-fluorescent tracer EMI-137 (targeting c-Met, peak emission at 675 nm range) might be useful for intraoperative imaging of PTC and nodal metastases. The investigators' aim is to investigate if the administration of EMI-137 is a feasible approach to detect PTC nodal metastases. Ultimately, this method might be useful to improve patient selection for CLND. Eventually, we might also be able to visualize multifocality, more selective lateral neck dissections and asses residual tissue after thyroidectomy. Ultimately, all of these strategies may reduce overtreatment, morbidity, and costs while maintaining the same or better effectiveness with a lower recurrence rate and improved quality of life.
