Active clinical trials for "Neoplasm Metastasis"

To determine safety, ablative zone, technical success rate and early safety data of recently introduced cool-wet electrode in eligible patients who are indicative for radiofrequency ablation (RFA) for liver tumors.

The purpose of this study is to determine a tolerable dose of radiation delivered by the CyberKnife system in two groups of patients with hepatocellular carcinoma (HCC).

The study wants to define the maximum tolerated dose (MTD), safety and efficacy of a short course radiation treatment in patients with complicated bone metastases.

Stereotactic ablative body radiotherapy (SABR) can be considered for patients with so-called "oligometastatic" disease. However, since this is a relatively new technique, information on the optimal scheduling is lacking. Even prospective randomized trials on SABR for oligometastases typically allow different fractionation schedules to be used. This is especially true for non-spine bone and lymph node metastases, where the literature is scarce to non-existent. There is also emerging evidence that SABR can stimulate the immune response, by a variety of mechanisms such as increasing TLR4 expression on dendritic cells, increasing priming of T cells in draining lymph nodes, and increasing tumor cell antigen presentation by dendritic cells. Again, it is not clear which fractionation schedule elicits the most robust immune response. Therefore, it is opportune to compare the most commonly used stereotactic regimens regarding toxicity, efficacy, and immune priming. This trial is a non-randomized prospective phase I trial determining a regimen of choice for patients with non-spine bone and lymph node oligometastases (≤ 3 lesions). The metastatic lesion(s) must be visible on CT and < 5 cm in largest diameter. A total of ninety patients will be consecutively included in three different fractionation regimens. They will be offered stereotactic ablative radiotherapy to all metastatic lesions in 5, 3 or 1 fractions. Dose-limiting toxicity (DLT), defined as any acute grade 3 or 4 toxicity, will be recorded as the primary endpoint. Overall acute and late toxicity, quality of life, local control, and progression-free survival are secondary endpoints. Liquid biopsies will be collected throughout the course of this trial, i.e. at simulation, after each fraction and at 6 months after the end of the radiotherapy. Translational research will focus on assessment of circulating cytokines and flow cytometry analysis of immune cells.

The aim of the trial is to optimize response rates and rates of secondary resections of metastases in patients with initially non-resectable metastatic colorectal cancer Liver Metastasis of RAS wildtype. The patients will be treated in two therapy groups: Experimental arm A: Chemotherapy with FOLFOXIRI + Cetuximab Standard arm B: Chemotherapy with FOLFOX + Cetuximab

The aim of the trial is to optimize response rates and rates of secondary resections of metastases in patients with initially non-resectable metastatic colorectal cancer Liver Metastasis. The patients will be treated with systemic chemotherapy With irinotecan plus hepatic arterial infusion With floxuridine and oxaliplatin

The main purpose of this study is to evaluate the safety of the study drug prexasertib in combination with ralimetinib in participants with advanced or metastatic cancer.

This research study is being conducted to assess the safety and feasibility of using a new developed bronchoscopic technology called electronavigational bronchoscopy to treat subjects with solid tumor in peripheral lung, who are inoperable or refused surgery. It will involve 10 sites in USA and Canada. Participation will last 6 months.

This research study is studying a combination of two drugs as a possible treatment for Leptomeningeal Metastases. The names of the study interventions involved in this study are: Ipilimumab Nivolumab

Gastrointestinal (GI) cancers account for the most common cancers. Despite recent advances in GI cancer treatments, the 5-year overall survival rate for these patients remain unacceptable, except for patients who are candidates for metastasis surgical resection. Strategies leading to a decrease of metastatic number and size will contribute to improve the probability to undergo a curative surgical procedure. Haploidentical Natural Killer (NK) cells can persist and expand in vivo following adoptive transfer and may have a role in the treatment of selected malignancies, since the failure to recognize the appropriate KIR ligand on a mismatched tumor cell can trigger NK cell elimination of that target cell. NK also express an activating Fc receptor that mediates antibody-dependent cellular cytotoxicity (ADCC) and production of immune modulatory cytokines in response to antibody-coated targets. Cetuximab, an IgG1 chimeric monoclonal antibody against colorectal cancers that expressed EGFR (epidermal growth factor receptor), improves overall survival and progression-free survival and preserves quality-of-life measures in patients with colorectal cancer in whom other treatments have failed. In an attempt to improve the outcome in GI cancers, we will conduct a phase I/II clinical trial assessing NK cell based immunotherapy. Patients with liver metastases related to a EGFR+ GI cancer, previously treated by a standard chemotherapy that did not achieve a complete response or a curative resection of residual metastases will be included in this phase I/II trial supported by the French National Institute of Cancer (INCA, PHRC 2005). This phase I/II study will involve 22 patients. The main objective of this study will be to demonstrate the safety of NK hepatic intraarterial infusion in association with cetuximab. Secondary objectives will include the assessment of the clinical efficacity of this strategy.
