Active clinical trials for "Neoplasm Metastasis"

For high-risk prostate cancer patients, detection of lymph node metastases is crucial to ensure optimal treatment. Standard treatment for these patients is radiotherapy or surgery. The surgery involves resection of the prostate and the pelvic lymph nodes. Currently, the most reliable method to confirm lymph node metastases is by histologic examination of the resected lymph nodes. Ideally, one should be able to detect lymph node metastases prior to treatment. Then, the treatment could be better adjusted to each patient. Imaging methods such as prostate specific membrane antigen positron emission tomography (PSMA-PET) can possibly aid the detection of lymph node metastases. In this study, the investigators want to test whether PSMA-PET or a combination of PSMA-PET and MRI (magnetic resonance imaging) can improve staging of lymph nodes before treatment.

The spread of cancer to the brain is referred to as brain metastases. Brain metastases are a common complication of cancer. This study is being done to determine whether the use of a new imaging agent, 18F-fluciclovine, is able to detect which patients are responding to radiation therapy. In addition, this study will look at the changes of the treated brain metastases using this imaging agent over time.

This study looks at dose escalation for five fraction stereotactic radiotherapy for patients diagnosed with brain metastases with tumors 2.1-4.0 cm in diameter or 4.1-6.0 cm in diameter.

This is a prospective, single arm, phase II trial to determine the local control at 6 months utilizing pre-operative stereotactic radiosurgery followed by surgery within 1 - 4 days in subjects with a diagnosis of 1-4 brain metastases and with an indication for surgical resection of at least one brain metastasis at the discretion of a neurosurgeon.

Stereotactic radiation therapy is an important and common method of treating brain metastases in patients with malignant disease. Today, however, there are no methods available to determine the metastasis' radiation sensitivity in advance and treatment responses can only be seen by changing of the size of the metastasis on conventional X-ray examinations, computed tomography (CT) and magnetic resonance imaging (MRI). Changes in the size of the metastases is something that is often seen weeks / months after treatment is completed. At Lund University Hospital, a new imaging technique, diffusional variance decomposition (DIVIDE), has now been developed. With this technique, the scatter in isotropic and anisotropic diffusion can be measured for each measuring point, which provides significantly more information about the properties of the tissue compared to current methods.

This research study investigates if SpotTM ink can help breast surgeons retrieve sampled lymph node as well as or better than the standard clip and radioseed guidance methods. The names of the novel study intervention involved in this study is: SpotTM ink tattooing The names of the standard of care study interventions involved in this study are: Core needle biopsy and/or fine needle aspiration Surgical Removal of the Lymph Nodes via clip and radioseed guidance

The purpose of the study is to determine in brain metastases and according to feasibility in liquid biopsies: Molecular alterations including in particular mutations, amplifications, Copy number gene variants and fusion transcripts identified by high-throughput sequencing; The rate of variation either in gain or in loss of expression of the different messenger Ribonucleic Acids by analysis of the transcriptome; Epigenetic alterations by methylation of deoxyribonucleic acid clusters by methylome chips.

The purpose of the study is to compare outcomes of laparoscopic versus open liver resection for colorectal metastases in a prospective and randomized study. The study will include all non-anatomic liver resections in our institution. The primary end point is that the use of laparoscopic technique significantly can reduce the frequency of complications to liver resection. Secondary end points are 5-year survival, immediate surgical outcomes, quality of life and degree of impairment of the immune system.

Stereotactic radiosurgery or hypofractionated radiotherapy of the resection cavity after metastasectomy in cancer patients with brain metastases

Eligible patients with high risk colorectal malignancy (T3/4, spread greater than 5mm, EMVI positive) will have additional surveillance of breath hold T1, T2 and DW-MRIs (no IV contrast) post surgery six monthly for three years. Findings of liver MRIs as reported by radiology PI will be shared with their local MDT who make decisions as appropriate, including the management of any identified liver metastases, according to local protocol.
