Active clinical trials for "Neoplasm Metastasis"

The prognosis of NSCLC patients with asymptomatic brain metastasis, who are not treated with SRS or WBRT has not been fully investigated yet. This randomized phase III trial is conducted to determine the exact role of SRS in NSCLC patients with asymptomatic oligo brain metastases whether early treatment with SRS would improve survival even in patients with asymptomatic brain metastasis.

The purpose of this multicenter study is to assess a diagnostic strategy concerning differential diagnosis between radiation necrosis and relapse in brain metastases treated with radiosurgery. Two non-invasive tests - positron emission tomography (PET) with 1F-fluoro-ethyl-tyrosine (FET) and magnetic resonance spectroscopy (MRS) - will be compared to histology in a cohort of patients presenting growing lesions 6 months after radiosurgical treatment. The results of this study should help to earlier diagnosis of recurrences after radiosurgery and to perform an appropriate treatment for patients.

In this study, the investigators assessed whether intraoperative Intraportal infusion of 5-FU and oxaliplatin is able to prevent liver metastasis in patients receiving curative colorectal cancer resection.

This cluster Randomised Control Trial is evaluating an intervention to support adolescent girls from marginalised communities in northern Karnataka State, South India to complete secondary school, thereby reducing their vulnerability to HIV infection from early marriage and entry into sex work at young ages. The intervention will test innovations to address both supply and demand side barriers to girls' completion of secondary school, and will have long-term educational and livelihood benefits, in addition to reducing vulnerability to HIV. School-based constraints will be addressed by improving academic outcomes through teacher training and academic support to students; addressing gender-related and skill-based gaps among teachers; training of local female teachers; and increasing the content knowledge of secondary school teachers. Demand side barriers will be addressed by reducing economic pressures that households face to withdraw girls' from school; building appreciation and value of girls' education; building family and community accountability for school attendance; creating safe spaces for girls and strengthening their agency; and engaging boys in promoting and supporting girls' education. Primary stakeholders will include teachers and students, especially adolescent girls in the school (7th to 10 the standard) from marginalized communities. Secondary stakeholders will include school development and management committees (SDMCs), families, boys and the communities that are served by the schools. 80 village clusters (40 intervention; 40 control) were randomly selected from 125 village clusters in Bagalkote and Vijayapura districts. The intervention will be implemented with village communities and high schools in 40 village clusters in Bagalkote and Vijayapura districts. The intervention will be implemented in collaboration with the Department of State Educational Research and Training (DSERT), Karnataka; the Adolescent Education Cell, Government College of Teachers' Education (CTE), Jamkhandi; and the Institute for Advanced Studies in Education (IASE), Gulbarga.

To investigate the response of temozolomide versus prophylactic cranial radiotherapy in preventing brain metastases in completed or partial remission limited small cell lung cancer patients.

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.

Based on evidence that radiation-induced damage to the hippocampus plays a considerable role in neurocognitive decline after cranial irradiation, hippocampal-sparing whole brain radiation therapy (HS-WBRT) has been proposed. This study will investigate the neurocognitive function and prognosis between HS-WBRT and conventional WBRT for the treatment of brain metastases from breast cancer.

This study will assess and compare the diagnostic performances and image quality of two WB 3D T1-weighted MR imaging sequences for bone and node staging in patients with prostate cancer : the FSE sequence and a gradient echo (GE) sequence. The latter sequence's main feature is its acquisition time of approximately 1.5 minutes, compared to 18 min for the FSE sequence, reducing the exam's acquisition time, patient discomfort and increasing machine availability.

To improve the function and welfare of late stage solid cancer subjects by: enabling subjects to benefit from a potentially promising drug under development assessing initial evidence of improvement in Pain VAS score assessing initial improvement in Performance Status (PS) assessing initial improvement in oxygen saturation whenever it is feasible

The purpose of this study is to test a new and possibly more accurate method of positioning patients with liver tumors in preparation for radiation treatment. The positioning of patients with liver cancer is important because the tumor moves a bit when you breathe and makes it hard to determine the right position of the tumor at the time of treatment. Also, depending upon what is in your stomach at the time of treatment, it may change the shape of the liver and make it difficult to plan the radiation treatment. As part of this study, we will take a new type of image of your liver in addition to the standard portal images. This new type of image is called a cone-beam image. It shows a much more detailed picture of the liver tumors than the standard portal images. Normally, marker seeds need to be placed near the liver metastasis for radiation treatment. If the results of this study show that the tumor can be positioned as accurately with the new images as with the old images, then future patients with liver tumors would not have to have marker seeds placed into their liver. The use of cone beam imaging for the setup of patients with liver tumors is new.
