Active clinical trials for "Neoplasm Metastasis"

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.

This clinical trial studies the use of sodium fluorine-18 (18F-NaF) plus fluorine-18 (18F) fluorodeoxyglucose (FDG) positron emission tomography (PET)/ whole body magnetic resonance imaging (WBMRI) to detect skeletal metastases in patients with stage III-IV breast cancer or stage II-IV prostate cancer.

The purpose of this study is to investigate whether bevacizumab helps 5-Fluorouracil (5-FU) be delivered to the tumor more efficiently. Bevacizumab has been shown to inhibit the formation of new blood vessels in tumors and works best in combination with drugs that require blood vessels for transportation. Based on other experiments, bevacizumab may work by improving the transportation of other drugs to the tumor.

Subjects are randomized to one of two treatment arms. All subjects are screened for eligibility within 28 days prior to randomization. The study consists of a treatment phase and a follow-up phase. Subjects are treated in repeating 4 week cycles.

A few studies have documented that some patients can be down-staged from an initially inoperable state to a potentially resectable state. Five-year survival in initially inoperable patients that ultimately come to a complete resection appears to be similar to patients who are resected at first presentation. The investigators goal is to assess the rate of conversion to complete resection in patients with initially inoperable liver-only metastases due to colorectal cancer after treatment with HAI of oxaliplatin with FOLFIRI and bevacuzimab systemic treatment.

This is a phase III randomized-controlled, single-blind study comparing the standard schedule for antalgic radiotherapy of a single fraction of 8.0 Gy delivered through three-dimensional conformal radiotherapy (3D-CRT) to a single fraction of 20.0 Gy delivered through stereotactic body radiotherapy (SBRT). The primary aim of this trial is to double the complete response rate. Secondary aims are to compare general response rates, duration of pain response, acute and late toxicity, HRQoL through patient-reported outcome measures (PROMs), pain flare, and re-irradiation need.

Trans arterial chemoembolization using Irinotecan Drug-eluting Beads before liver surgery for patients with primarily unresectable colorectal liver metastasis

This study is designed to evaluate whether advanced magnetic resonance imaging (MRI) techniques such as dynamic susceptibility-weighted contrast-enhanced perfusion MRI may be used to predict treatment response of brain metastasis after radiosurgery.

In this randomized multicentric phase II study, patients with colorectal carcinoma with resectable hepatic metastasis will be randomized to treatment with dendritic cells or to observation, following conventional treatment with surgery and chemotherapy.

Background: Anatomical (traditional) stereotactic body radio therapy(SBRT) treatment planning assumes homogenous distribution of function in the normal liver tissue. In functional treatment planning, additional information on distribution of the function derived from functional imaging of normal tissue is taken into account. by functional treatment planning it becomes possible to prioritize and spare the best functioning part of an organ. Aim: To test whether functional treatment planning based on 18-FDGal PET/CT may spare the best functioning liver tissue. Endpoints: Reduction in hepatic systemic clearance (K) in the dynamic 18-FDGal PET/CT scan one month after SBRT compared to the baseline status in sub-volumes recieving 15 Gy or higher. Secondly, the investigators will evaluate the toxicity to SBRT by a toxicity scoring system that includes biochemical measures as well as symptomatic scores.
