Active clinical trials for "Neoplasm Metastasis"

Phase III trial comparing local control and side effects after fractionated stereotactic radiotherapy and single session radiosurgery in patients with larger brain metastases (2-4 cm)

The primary objective is to patient-reported Quality of Life related to complete control of Radiation Induced Nausea and Vomiting (RINV) between standard palliative radiotherapy and VMAT. Secondarily, we will assess rate of complete control of RINV. However, the investigators hypothesize that there will be no difference in pain response between the two arms, because they are receiving the same dose.

In patients with a limited oligometastatic burden (cancer has spread but is not yet considered metastatic), emerging evidence suggests that treatment of all sites of disease with ablative therapies can improve patient outcomes, including overall- and progression-free survival. The application of Stereotactic Ablative Radiotherapy (SABR) for patients with 4-10 metastatic deposits appears promising, yet it is unclear if all patients with greater than 3 oligometastatic lesions benefit from ablative therapies in terms of improved Overall Survival (OS), Progression Free Survival (PFS), or quality of life. The purpose of this study is to assess the impact of SABR, compared to standard of care treatment, on overall survival, oncologic outcomes, and quality of life in patients with a controlled primary tumor and 4-10 metastatic lesions.

This will be a phase II trial testing if the combination of stereotactic ablative body radiotherapy (SABR) and L19-IL2 improve the progression-free survival in patients with limited metastatic non-small cell lung cancer (NSCLC). The trial consists of one cohort with two arms; C-arm and an E-arm. Patients with oligometastatic disease will receive SABR to minimal 1 and max all metastatic sites (max 5 sites irradiated) and patients with diffuse metastatic lesions (6 to max 10) will receive radiotherapy to max 5 sites. In the experimental arm, immunotherapy will be given after irradiation.

Although angiographic embolization has been introduced for preoperative management of spine metastases in 1975 and is suggested today by many authors in the management of such pathologies, it needs to be confirmed by RCT. It is a minimally invasive procedure, not free from complications. The recent meta-analyzes, due to the limited number of patients included are not exhaustive about the effectiveness of embolization in the reduction of the intraoperative bleeding, especially in the context of poor / moderate metastasis vascularization. We want to evaluate the efficacy of preoperative angiographic embolization of intermediate / poor vascularized spine metastases in reducing intraoperative blood loss during excision surgery.

This is a multi-center phase III randomized controlled study to assess the efficacy of Gefitinib alone and Gefitinib combination with Pemetrexed/platinum on patients with brain metastasis from non-small cell lung cancer(NSCLC) harboring EGFR mutation type by intracranial PFS(iPFS),also PFS ,DCR and OS.The side effect is evaluated as well.

This is a Phase II study to determine the efficacy of SBRT to treat liver metastases in patients with Colorectal Adenocarcinoma, Carcinoma of the Anal Canal and Gastrointestinal Neuroendocrine Tumors that are not amenable to surgery. Patients should have no evidence of extra-hepatic disease or have disease that is planned to be treated with curative intent. Therefore, SBRT is being considered as a potentially curative procedure.

This is a phase 1b/2 study to determine the safety and effectiveness of the combination of pembrolizumab and idelalisib in NSCLC patients whose disease has stopped responding to immune therapy. This study is being done to see if adding another immune modulator (idelalisib) to standard pembrolizumab will increase response rates, compared to the response seen with pembrolizumab alone.

The purpose of this study is to assess the safety and feasibility of Magnetic Resonance Imaging-guided focused ultrasound (MRgFUS) in patients with epilepsy whose medicines are not working well. The ExAblate transcranial system is the name of the device that will be used to create and send ultrasound waves through the scalp and skull precisely to a small structure located in the center of the brain. This structure is known as the "Anterior Nucleus", and is an important region in the brain that may cause the seizures. Safety will be measured by recording and analyzing any adverse effects that may occur from the day of the experimental surgery through 12 months following the surgery.

For newly-diagnosed patients with brain metastasis, whole brain radiation therapy (WBRT) probably remains a common palliative management even for those with oligometastatic brain disease. However, WBRT-related late sequelae, particularly a decline in neurocognitive functions (NCFs), are a major concern. More importantly, in patients with limited brain metastases and a fair/good performance status, sparing the radiosensitive and vulnerable structures which are responsible for essential NCFs during the WBRT course is one of the reasonable strategies to postpone and prevent the development of WBRT-induced neurocognitive impairments. Actually, radiation-related neurocognitive dysfunction is usually characterized as a decline involving learning and memory, in which the extremely radiosensitive hippocampus indeed plays a critical role. In addition to the neurocognitive preservation by virtue of sparing the radiosensitive structures like the hippocampus, durable intracranial tumor control critically depends on an escalated radiotherapeutic dose level which is adequate enough to eradicate gross metastatic brain lesions. Therefore, in order to achieve both hippocampal sparing and simultaneous integrated boost(s) to gross metastatic foci, a specialized WBRT technique, hippocampal avoidance during WBRT plus simultaneous integrated boost (SIB) will be adopted in this prospective study. Moreover, the dose-effect relationship would be analyzed in order to explore the correlation between the equivalent uniform dose (EUD) irradiating the hippocampus and the neurocognitive change/decline after the above WBRT course measured by objective neurocognitive test tools. Newly-diagnosed cancer patients harboring 1-3 gross metastatic lesions but still in fair/good performance statuses are potentially eligible. All recruited patients should receive baseline functional brain MRI examination and baseline neurobehavioral assessment. Treatment planning will be designed via the technique of volumetric-modulated arc therapy (VMAT) to achieve both hippocampal avoidance and simultaneous integrated boost(s) to gross metastatic lesions. Except for the above regions for which conformal avoidance or SIB is attempted, the prescribed dose to the remaining brain parenchyma will be consistently 3000 cGy in 12 fractions. Accordingly, a battery of neuropsychological measures, which includes 7 standardized neuropsychological tests (e.g., executive functions, verbal and non-verbal memory, working memory, and psychomotor speed), is used to evaluate neurobehavioral functions for our registered patients. The primary outcome measure is delayed recall, as determined by the change/decline in verbal memory or non-verbal memory, from the baseline assessment to 4 months after the start of the WBRT course. This prospective cohort study aims to examine thoroughly the impact of a specialized WBRT technique, integrating both simultaneous integrated boost(s) delivered to gross metastatic foci and conformal hippocampal avoidance, on the status of NCF change/decline in patients with oligometastatic brain disease. It is anticipated that intracranial local control will be more sustainable and durable resulting from the escalated focal dose of SIBs. Ultimately, we also expect the dose-effect relationship will be clearly demonstrated after investigating the correlation between the hippocampal dosimetry and the status of NCF change/decline after receiving HA-WBRT plus SIB.
