Active clinical trials for "Neoplasm Metastasis"

The overall objective of this study is to assess the safety and efficacy of the LUM Imaging System in imaging primary and metastatic cancer in the brain. This includes selecting a dose to determine the initial efficacy of LUM015 for the molecular imaging of low-grade gliomas, glioblastomas and cancer masses that have metastasized to the brain.

non-intervention、real world study； Effect of timing and regular treatment of zoledronic acid on the incidence of SREs in breast cancer patients

Sodium zirconium cyclosilicate (SZC) has been demonstrated for its serum potassium-lowering efficacy and safety in hyperkalemia hemodialysis patients. However, the effects of SZC during the perioperative period remained unknown. This experiment aimed to determine whether using SZC would impact the serum potassium levels in patients with maintenance hemodialysis after parathyroidectomy (PTX).

A single-center observational clinical trial will be performed for metastatic spinal tumors by stereotactic radiotherapy using TomoTherapy. In this study, we will explore the local control rate (LCR), disease-free progression time (PFS), overall survival time (OS), and pain relief in patients with spinal metastasis, so as to provide a basis for developing relevant guidelines or consensus.

Bladder cancer is one of the most frequent malignant tumors of the urinary system in China, seriously threatening the life safety of patients. The main treatment methods for bladder cancer include surgical resection, radiotherapy and chemotherapy, immunotherapy, and targeted therapy, among which surgical resection is still the only reliable radical treatment at present. Lymphatic metastasis is the main mode of metastasis of bladder cancer, and preoperative diagnosis is of great significance to determine whether radical surgical treatment can be performed for some patients with advanced bladder cancer. Recent studies reveal that exosomes, as key signaling molecules in the tumor microenvironment, have been confirmed to be associated with various tumor progressions. Our previous study showed that lncRNA-ELNAT1 highly expressed in urine exosomes of bladder cancer patients can promote lymphatic metastasis of bladder cancer by inducing lymphatic angiogenesis, and is associated with poor prognosis of patients. However, whether exosome ELNAT1 can be used as an independent preoperative predictor of lymph node metastasis of bladder cancer needs to be explored in further clinical trials, and this study will further clarify the association between the two. In this study, urine exosomes were collected from positive and negative control patients with lymph node metastasis of bladder cancer, and the ROC curve was statistically analyzed and fitted to determine whether exosome ELANT1 could be used as an independent predictor of lymph node metastasis of bladder cancer.

This study will evaluate the efficacy, safety, and effect on quality of life of oral ibandronate (Bondronat) in participants with breast cancer and metastatic bone disease. The anticipated time on study treatment is 25 weeks, and the target sample size is 50 individuals.

The effect of nivolumab on symptomatic brain metastases is currently unknown. This phase 2 clinical trial will be the first to evaluate this intracranial effect in humans, with the aim to give these patients the possibility to be treated with anti-PD-1. Besides the objective response rate, long term benefits in this patient category will be evaluated by measuring survival in terms of progression free survival and overall survival. Furthermore safety and tolerability of administration of this drug in patients with symptomatic brain metastases will be studied, as this is the first study for nivolumab in this specific patient category.

After standard multimodal therapy, the prognosis of relapsed and unresectable high-grade osteosarcoma is dismal and unchanged over the last decades.Thus, the investigators explored apatinib activity in patients with relapsed and unresectable osteosarcoma after the failure of first-line or second-line chemotherapy. Patients >16 years, progressing after standard treatment, were eligible to receive 500 mg or 750 mg of apatinib once daily until progression or unacceptable toxicity. The primary end point was progression-free survival (PFS) at 4 months and objective response rate (ORR). Secondary objectives were PFS, overall survival (OS), clinical benefit rate (CBR), defined as no progression at 6 months and safety.

This study will evaluate renal function in participants with metastatic bone disease due to breast cancer receiving intravenous (IV) infusions of ibandronate (Bondronat) 6 milligrams (mg), over either 15 minutes or 60 minutes, every 3 weeks. Efficacy and safety of ibandronate in the 2 groups of participants will also be compared. The anticipated time on study treatment is 7 months, and the target sample size is 318 individuals.

Some cancers can spread, or metastasize, to the brain. When they do, treatment often involves surgery and/or radiation. Optimal treatment of brain metastases would maximize disease control and minimize toxicity (or side effects), and improve the quality of life of patients. A common type of radiation used for brain metastases is called whole brain radiation, which treats not just the cancer that can be seen on scans (i.e., gross disease), but the smaller sites of cancer that may not be visible (i.e. subclinical disease). Fractionation is used to describe repetitive treatments in which small doses (fractions) of a total planned dose are given at separate clinic visits. The most common dosing regimen is 30 Gray (Gy), using 3 Gy per fraction over 10 fractions. Previous studies have suggested that using intensity modulated radiation therapy (IMRT) may be a safer way to deliver higher doses to gross disease and lower doses to the rest of the brain that may contain subclinical disease. This approach may spare the rest of the brain from radiation complications and side effects. The goal of this study is to determine whether using IMRT to treat brain metastases is more effective than current standard whole brain radiation in controlling gross disease and whether patient quality of life and hair loss is improved compared to previous studies using whole brain radiation.
