Active clinical trials for "Neoplasm Metastasis"

Metastatic vertebral disease is a major hazard for oncological patients because the performance and life quality will substantially deteriorate if presence of neoplastic compression. And the subsequent treatment and overall survival will be dismal. Restoration of vertebral stability and prevention of neurological deterioration are treatment goal. Surgical treatment is an important and effective method for metastatic spinal disease. For aggressive surgical method, long-term control is better. However, massive bleeding is often encountered in this surgery, and preoperative evaluation is very important for successful operation. Imaging play major role in this tasks. MRI, angiography, and nuclear medicine studies are common modalities, but take longer time and are often suboptimal. Dual-energy CT has the ability to detect contrast medium enhancement in osseous structure. It therefore is a potential optimal tool in the evaluate the metastatic spinal malignancy. It also own advantage of rapid scanning, optimal resolution, and easy reformatting.In this study, we intend to use this tool to establish the imaging biomarker for tumoural vascularity, to compare its performance with other modalities, and to investigate its optimal imaging condition, which will bring valuable information for treatment planning for aggressive spinal surgery before metastatic disease.

A propensity- matched study was conducted to investigate the feasibility and safety of adding temozolomide to hypofractionated stereotactic radiotherapy for large brain metastases.

The purpose of this study is to identify mechanisms associated with acquired immune escape by comparing baseline and at-progression tissue samples from participants who derive clinical benefit from CPI treatment of metastatic cancer or hematologic malignancies.

This is a monocentric, open label, randomized Phase II study in patients with brain metastasis from melanoma, lung or breast cancer, who require treatment with high-dose dexamethasone, as defined as a minimum of 8 mg daily based on the clinician judgment, for at least three weeks, with or without radiation therapy. The aim is to investigate the metformin efficacy in preventing the onset of glucocorticoid-induced diabetes and other metabolic perturbations in patients with brain metastases from melanoma, lung or breast cancer.

The aim of the present study is to identify deregulated miRNAs in oncological patients with bone metastases present within the circulating exosomes and responsible for the biological mechanisms involved in the process of bone metastasis, in order to obtain a panel of biomarkers predictive of this risk. Through appropriate molecular screening methods a specific panel of significantly deregulated miRNAs will be identified; subsequently bioinformatics analyzes through the use of dedicated databases will be carried out, based on literature data and predicted protein targets in order to identify their potential role in tumor progression, and especially in the onset of bone metastases. Attention, therefore, may be focused on the individual miRNAs identified through individual analysis analyzes of gene expression. These biomarkers could also serve as therapeutic targets, allowing to improve the effectiveness of current therapies and to undertake timely and appropriate therapeutic choices, developed on the basis of the patient's molecular characteristics

Cancer which has spread to the bone, causing bone metastases (bone tumours) can weaken bone health and increase risk of fractures (breaks). Consequently, patients can be unsure whether to exercise and health professionals can be unsure what exercise advice is suitable. Despite this, it is well known that exercise improves quality-of-life for patients with bone metastases and therefore it is important that exercise is prescribed to these patients. This study aims to increase understanding of the link between daily exercise and risk of fracture in patients with bone metastases.

We retrospectively looks at the impact of the margin status and its size in mm on the recurrence rate in colo-rectal liver metastasis surgery.

Use exosome microfluidic chips to establish a combination of exosome subgroup level (exosome barcode) markers for the early diagnosis of osteosarcoma lung recurrence, and establish the basis of microfluidic chip based exosome biomarker for monitoring the early therapeutic response of the second-line therapy for recurrent osteosarcoma.

Liver metastasis may not be detected by CT and MRI due to their small size while they can be detected by EUS. Also, EUS-FNA has a great impact in improving the diagnostic accuracy of EUS. Objectives: To assess the feasibility of EUS in the detection of occult small hepatic focal lesions at the time of primary tumor staging, not seen by CT or MRI.

The main purpose of this research is to verify the safety of CEA targeted chimeric antigen receptor T cells and to determine the proper dosage of CAR T cells infused.
