View clinical trials related to Brain Metastases.
Filter by:Lung cancer is a leading cause of death worldwide. Brain metastases manifest as the first site of disease failure in between 15-30% of patients with non-small cell lung cancer (NSCLC). The standard treatment for patients with multiple brain metastases is whole brain radiotherapy but this results in only a modest survival of 3-6 months. Drugs that can enhance the effect of cranial irradiation (radiosensitizers) may improve the the response rates. Erlotinib (Tarceva) is an oral agent that has been registered for treatment in patients with metastatic NSCLC. Erlotinib has shown tumor activity in patients presenting with brain metastases, and preclinical studies show that it may be a radiosensitizer. As a prelude to studies investigating the combination of Erlotinib and cranial radiotherapy, the present study will be performed to evaluate the safety of combining both these treatments.
This study is conducted to compare the contrast effect and safety of SH L562BB with ProHance, which has already been approved as a pharmaceutical product of similar indication.
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 this research study is to determine the safety of combining lapatinib plus radiation in patients with breast cancer that has spread to the brain. Depending upon the participants cancer, they may also have stereotactic radiosurgery (SRS). Lapatinib s a compound that may stop cancer cells from growing abnormally. It is thought that lapatinib might also make cancer cells more sensitive to radiation. This drug has been used in other research studies in women with breast cancer, and information from those other research studies suggests that lapatinib may help to shrink or stabilize breast tumors both inside the brain and outside the brain.
Purpose: The primary objective of this study is to determine if chemotherapy with carboplatin and temozolomide significantly affects the response rates, or size of disease, in patients with brain metastases, originating from cancer in other parts of the body, compared to patients who have already been treated with radiation. Survival, causes of death, recurrence of disease in the central nervous system, toxicity, and quality of life will all be measured as secondary objective in this study.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. PURPOSE: Phase I trial to study the effectiveness of stereotactic radiosurgery in treating patients who have brain tumors.
