Active clinical trials for "Neoplasm Metastasis"

Primary Objective: Determine the interindividual range and median of individual maximum tolerated doses of valproic acid administered as one time evening dose in conjunction with a dose oral etoposide (50 mg/m2/day for children, but only 25mg/m2/day for adults to start) for four different age groups. Secondary Objectives: Determine the qualitative and quantitative toxicity and reversibility of toxicity of valproic acid in conjunction with oral etoposide, To investigate the clinical pharmacokinetics of valproic acid when given in conjunction with oral etoposide, To describe quality of life of patients with relapsed, or progressive central and peripheral nervous system tumors when treated with oral valproic acid and etoposide, To observe and describe the response pattern of progressive central nervous system tumors treated with oral valproic acid and etoposide, To observe and describe event free survival time and overall survival time of patients with relapsed, or progressive central nervous system tumors when treated with oral valproic acid and etoposide, To determine if histone deacetylase activity and topoisomerase expression in lymphocytes of patients is related to valproic acid levels, and To determine, if the individual maximal tolerated dose (iMTD) depends on the initial performance status of the patient in the beginning of the treatment.

The purpose of the study is to evaluate the effectiveness of radiofrequency ablation by pathological correlation and to characterize the tissue response after treatment of primary and secondary pulmonary tumors.

ALSYMPCA (ALpharadin in SYMPtomatic Prostate CAncer) is an international Phase III clinical study to evaluate the efficacy and safety of Radium-223 dichloride in patients with hormone refractory prostate cancer and skeletal metastases.

The purpose of this research study is to find out what IG-IMRT radiation dose works best for treatment of disease in bone or soft tissues. This protocol will study what dose level may work most effectively. The first part of study will treat 10 patients with 22 Gray. Gray (Gy) is the unit that is used to describe the dose of radiation that is being given to a person with cancer. After we confirm that 22 Gy is a safe and sufficient amount of radiation, we will then treat another group of patients with 24 Gy and so on until we reach 28 Gy. Each dose level starting with 24 Gy will enroll at least 20 patients per treatment site (bone, bowel and/or spine). Patients will be enrolled in each treatment category until 20 patients in each strata reach an evaluable time point of 3 months post-RT. When we understand what dose works best and has the least amount of bad effects, the study will then look to see how well the patients do after the radiation therapy. This study is trying to see how your doctor can best treat the cancer that has spread to the other parts of your body.

The goal of this clinical research study is to learn how well magnetic resonance thermal imaging (MRTI) can check the amount of tumor being destroyed using a therapy called laser ablation (a procedure that uses lasers to create heat that is designed to destroy cancer cells).

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying the side effects of imatinib mesylate and to see how well it works in treating patients with liver metastasis from a gastrointestinal stromal tumor.

This study will evaluate PTK787, a new oral drug that stops blood vessel development, in combination with Paclitaxel in patients with advanced solid tumors.

Tamoxifen is a classical treatment for breast metastatic cancer after 3rd generation anti-aromatase hormonotherapy in adjuvant or in metastatic line. The Tamoxifen efficacy is lowered by the hormonoresistance mechanisms due to the primary use of the anti-aromatases. The Pi3K-AKT-mTor pathway is frequently associated to the hormonoresistance mechanisms. This study is aimed to check if the inhibition of this signal transduction pathway by a synthetic mTor inhibitor (Everolimus) could improve the efficacy of the Tamoxifen.

The main purpose of this study is to investigate the efficacy of bevacizumab, etoposide and cisplatin in treating breast cancer patients with central nervous system metastasis (including brain parenchymal and leptomeningeal metastasis).

Patients with new or recurrent spine metastases are currently treated with low doses of radiation delivered in up to ten treatments (wide-field radiation therapy). Stererotactic body radiotherapy (SBRT) is a technique in which high doses of radiation targeted precisely to the metastases to be treated are administered in a small number of sessions, thus reducing the radiation damage to the surrounding tissue and areas of the spine. The purpose of this study is to evaluate the efficacy of spine SBRT as an alternative to conventional radiation for patients with no prior radiation, prior radiation, and in the post-operative patient
