The incidence of brain metastases (BM) in metastatic breast cancer is increasing, due to the improvement in the control of systemic disease, and due to an improved detection through imagery. The treatment management of single BM remains controversial. Indeed, even though it is widely accepted that local treatment increases the median survival time in patients having a good prognostic status, the adding of "adjuvant" whole-brain radiation therapy (WBRT) is currently subject to controversy, due to its potential toxicity. Yet, two randomized trials have demonstrated a clear increase in intra-cerebral recurrence and in death from neurologic origin in case of absence of "adjuvant" WBRT, without change in overall survival (but overall survival was not a primary endpoint in any of these studies). The data from literature on cognitive toxicity (CT) of WBRT on BM are scarce and sometimes controversial. CT of WBRT affects the subcortical frontal functions. It is postulated that the alteration of hippocampal neurogenesis (mainly due to inflammation process), situated in the subgranular zone of the dentate gyrus, has an essential role in the development of these brain dysfunctions. It has been shown that the incidence of BM in the hippocampal region (hippocampus + 5mm expansion) is low, in the range of 8,6%. New irradiation techniques, in particular intensity-modulated radiotherapy associated with rotational radiotherapy, allow to modulate the dose on an intra-cerebral structure, all the while distributing an adapted dose to the remaining brain. This prospective, randomized study, will compare, through a battery of neuropsychological tests, the cognitive impact of WBRT of 40 Gy in 20 fractions with or without hippocampal avoidance by intensity modulated radiotherapy, in patients presenting with a single operated brain metastasis of breast cancer. If the hippocampal avoidance leads to a significant improvement in cognitive function, this radiotherapy scheme could become the standard postoperative treatment to be proposed to patients presenting the best prognostic factors. This would allow to prevent long-term cognitive deficit, while preserving WBRT benefit on intra-cerebral control. Justification of evaluation criteria : Principal criteria : Evaluation criteria to assess cognitive toxicity have been selected on the basis of the recommendations from C. Meyers and P. Brown, who propose an adapted test battery to evaluate memory, verbal function, visual and motor coordination, and executive function. The selected tests have been validated, also in French. They comprise HVLT-R (Hopkins Verbal Learning Test Revised), COWAT (Controlled Oral Word Association Test), Grooved Pegboard test, TMT A and B (Trailmaking tests A and B), and MMSE. The calculation of patient numbers was based on the HVLT-R test, as memory is thought to be the most frequently affected domain. The tests will be performed before treatment ("baseline" cognitive function), at 4 months and at 12 months. In case of a missing answer to the evaluation tests, the reason(s) for not answering will be noted. Secondary criteria : Quality of life : QLQ-C30, QLQ-BN20, ADL, IADL Intra-cerebral Progression-free survival (PFS) Overall survival.
A phase II trial evaluating Cabazitaxel in patients with brain metastasis secondary to breast and non-small-cell lung cancer (NSCLC). OBJECTIVES: Primary: The purpose of this study is to determine if cabazitaxel can induce a reduction in the size brain metastasis in metastatic HER2-negative breast cancer and NSCLC with brain metastasis who were not previously treated with whole brain irradiation or require immediate brain irradiation. Secondary: - To determine the effect of cabazitaxel on the time to initiating whole brain irradiation or radiosurgery - To determine the effect of cabazitaxel on the time to developing neurological symptoms - To determine the effect of cabazitaxel on the time to disease progression in the brain - To determine the effect of cabazitaxel on the time to disease progression outside the brain. This will be evaluated separately for the breast and NSCLC cohorts To determine the objective extra-cranial response (if applicable). This will be evaluated separately in the breast and NSCLC cohorts - To determine the safety of cabazitaxel
Background and purposes:Chloroquine (CLQ), an antimalarial drug, has a lysosomatrophic effect associate with increase the sensibility of Radiation through leakage of hidroliticenzimes, increase of apoptosis, autophagy mediated by lysosomalhidrolases and increase of oxidative stress "in vitro". In this phase II study we evaluated the efficacy and safety as radiosensitizing of the Chloroquine plus concomitant 30 Gray (Gy) of Whole-brain irradiation (WBI)in patients with brain metastases (BM) from solid tumors.
a. VEGFRs may be the biomarker which can predict the effect of bevacizumab in non small cell lung cancer
This research is being done to determine if a short course of Chloroquine (five weeks) before, during and after whole brain radiation therapy (WBRT) will improve the overall survival of subjects being treated for brain metastases.
EGFR-TKI is good for the patients with EGFR-mutant non-small cell lung cancer.We design this clinical trail to confirm if the efficacy of Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor(EGFR-TKI )(ICOTINIB) is better than whole brain irradiation for the patient with EGFR-mutant non-small cell lung cancer.
Vorinostat is a potent and well tolerated HDAC inhibitor. It has been reported to enhance radiosensitivity of cancer cells. We hypothesize that the addition of vorinostat to WBRT may increase therapeutic efficacy for patients with brain metastases.
The purpose of this study is to determine whether the use of Trental and Vitamin E can help reduce the incidence of radiation necrosis (a lesion that usually occurs at the original tumor site) after radiosurgery. These two drugs are commonly used to treat radiation necrosis when it occurs but the hope is that these drugs can be used to prevent radiation necrosis from ever occurring.
Background: - There are no standardized sets of tests to measure changes in neuropsychological functioning in patients treated for brain metastasis (cancer that has spread beyond the original site to the brain). - Neuropsychological function has an important effect on quality of life and should be included when determining treatment options. Objectives: - To find out if there is a change in patients cognitive (thinking) and daily functioning after standard radiation treatment for brain metastasis that can be measured with tests. - To see if any changes on these tests are related to patients response to radiation therapy. Eligibility: - Patients 18 years of age or older who have cancer that has spread to the brain. Design: - Patients receive a 2-week course of radiation therapy to the brain, given daily 5 days a week. Some patients may require stereotactic radiosurgery (an additional boost of radiation therapy to specific sites of brain metastasis). - Patients have the following evaluations before and after treatment to determine changes in cognition and functioning: - Neuropsychological testing to measure cognitive (thinking) abilities like memory, attention, processing speed, and reading, and fine motor skills. - Questionnaires to assess quality of life and daily living skills. - Patients have MRI scans and blood and urine tests. - At the completion of radiation treatment, patients return to the clinic for follow-up visits at 1, 2, 4, 6, 9 and 12 months for blood and urine tests, physical examination, MRI of the brain, neuropsychological testing and assessments of quality of life and daily living skills.
