Filter by:Brain metastases occur in 20-40% of patients with primary extracerebral tumors. Despite important advances in therapy of malignant solid tumors and treatment of 1-3 brain metastases, multiple brain metastases continue to present a significant problem in attempting to prevent progression of disease and limit morbidity associated with therapy. The majority of patients who develop brain metastases have a short survival, effective palliation being transient. The median survival after diagnosis is as low as 3-6 months. However, there is some evidence that selected patients survive prolonged periods with vigorous therapeutic approach. Specific therapeutic options are surgery, chemotherapy, conventional fractionated whole-brain radiotherapy (WBRT) and radiosurgery. Radiosurgery allows delivering of a single high dose fraction of radiation to targets of 3-3.5 cm maximum diameter. In patients with newly diagnosed brain metastases, a rapid decrease of symptoms, local tumor response rate of 73-90% and a median survival of 7-12 month have been reported. WBRT alone is the treatment of choice for patients with multiple brain metastases, and for patients with single brain metastases not amenable to surgery or radiosurgery. Median survival after WBRT alone is 3-6 months. WBRT and radiosurgery boost have been shown to improve survival in RPA class I patients and in patients with favorable histological status and squamous cell or non-small cell lung tumors. All randomized trials showed improved local control with the addition of radiosurgery to WBRT (Andrews, 2004). WBRT in conjunction with radiosurgery improves local control and reduces the risk of new distant brain metastases, but most studies support that combined radiosurgery and WBRT does not improve the overall survival expect for patients without evidence of extracranial disease. Helical Tomotherapy (HT) allows as a sole modality a new treatment option: Using HT, the advantage of applying a highly conformal boost dose to the metastases and WBRT can be combined in one treatment session. Therefore, it allows applying a high dose to multiple brain metastases in the sense of an integrated boost. The focus of this study is to investigate the efficacy and safety of WBRT with an integrated boost using this new treatment modality in comparison to the effects of conventional WBRT alone. The principal objective of the trial is to assess the therapeutic efficacy of WBRT as compared to WBRT combined with integrated boost with HT delivered to patients with 2-10 brain metastases of solid tumors. The secondary objective is to evaluate the safety of WBRT as opposed to WBRT combined with integrated boost as delivered by HT in patients with 2-10 brain metastases.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether radiation therapy is more effective when given alone or together with temozolomide in treating brain metastases secondary to breast cancer. PURPOSE: This randomized phase II trial is studying how well radiation therapy given together with temozolomide works compared with radiation therapy given alone in treating women with brain metastases and breast cancer.
The purpose of this study is to investigate whether TAC plus FOLFOX4 or TACE plus folfox4 are able to improve resection rate and overall survival in patients receiving primary colorectal tumor resection than given FOLFOX4 only.
Non small-cell lung cancer (NSCLC) accounts 85% of all lung cancer.The development of brain metastasis diminished life expectancy to less than one year with a median survival of less than three months. In NSCLC cancer, approximately 50% of patients with locally advanced disease develop brain metastasis at some time during the natural of disease. The central nervous system constitutes the first site of recurrence in 15 to 40% of these patients. Microarrays evaluate the diagnosis, treatment and prognosis of lung cancer.There are no studies that specifically evaluate the relationship between a genetic profile of NSCLC and metastasis to the CNS, with the purpose of distinguishing a subgroup of patients that will benefit of prophylactic treatment.What is the association between a genetic profile on NSCLC and the development of CNS metastasis.Obtaining a genetic profile from the primary NSCLC tumor cells, by using microarrays, we can predict the development of CNS metastasis arise a subgroup of patients that could benefit from prophylactic cranial radiation with which their quality of life and prognosis most probably will increase.Objective:Determine the association between a genetic profile from the primary tumor cells and the development of central nervous system metastasis in patients with non small-cell lung cancer.A genetic profile from the primary tumor cells are associated with the development of central nervous system metastasis in patients with NSCLC. A clinical, prospective, analytic, open, non randomized, prognostic and observational cohort with 66 patients with NSCLC who authorize a biopsy study from February, 2008 to December, 2012, INMEGEN institute will be in charge of performing the microarrays and the computer analysis in order to obtain the different genetic profiles that will be differentially expressed related with CNS metastasis risk profiles. Patients will be followed-up by means of the external consult of lung neoplasms. The statistical analysis will be performed using tests like Student's t or Mann-Whitney's U test. A multivariate analysis of logistic regression will be performed. Global survival time will be analyzed using Kaplan-Meier's technique and the comparison between groups will be performed with log-rank test. The adjustment for potential confusors will be performed using multivariate regression analysis. For result representation, we will use tables and graphs and pertinent measures will be taken to disclose the study.
The purpose of this study is to evaluate the potential of [18F]-ML-10 to serve as an imaging tool for the early detection of response of brain metastases to radiation therapy. Such early detection may help early identification of responsive and non-responsive lesions. The experimental design of the present study aims to evaluate the potential of PET imaging with [18F]-ML-10 to address the currently unmet clinical need for very early (within one day)assessment of response to therapy. Currently, response assessment is available only after several weeks or months after completion of therapy, when tumor shrinkage can be detected by anatomical imaging (by MRI). Early detection of tumor response to treatment is now widely-recognized as a highly-desirable goal in oncology, and is respectively the target of intense research worldwide. In the future, the option to know early upon treatment administration, that the treated tumor is a non-responsive, may improve clinical management of patients with brain metastases of solid tumors.
Family usually had a lot of burden to tell the truth to patients. The purpose of this study is to assess the effect of education materials and family conference for advanced cancer patients and family.
This is a global, multicenter, open-label safety extension study. Participants receiving single-agent trastuzumab emtansine or trastuzumab emtansine administered in combination with other anti-cancer therapies in a Genentech / Roche-sponsored parent study who are active and receiving benefit at the closure of parent study are eligible for continued treatment in this study.
RATIONALE: Morphine and ibuprofen help lessen pain caused by pleurodesis. It is not yet known whether one drug is more effective than the other in lessening pleurodesis-related pain or whether the size of the chest drain tube affects pain. PURPOSE: This randomized clinical trial is studying ibuprofen to see how well it works compared with morphine in treating pain in patients undergoing pleurodesis for malignant pleural effusion.
This study aims to discuss the efficacy and safety of neoadjuvant chemotherapy with XELOX regimen (oxaliplatin plus capecitabine) .
The purpose of this prospective multicenter trial is to investigate the value of molecular markers in endometrial cancer for predicting lymph node metastasis and prognosis in relation to treatment.
