Active clinical trials for "Neoplasm Metastasis"

This study aims to evaluate the efficacy of silibinin in preventing recurrence in the brain after complete resection of a brain metastasis (BM) from non-small-cell lung cancer (NSCLC) or breast cancer (BC).

Peritoneal disease at initial presentation for patients with gastric adenocarcinoma (GA) is frequent, with 15-31% of patients presenting with peritoneal metastases (PM) at surgical exploration. The prognosis of patients with PM is poor, overall survival (OS) ranging from 8 to 13 months, reinforcing the importance of optimal patient selection before surgical management of GA. Indocyanine Green (ICG) fluorescence imaging for intraoperative detection of PM has been described in recent literature as a useful tool in patients undergoing cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal malignancies to increase the detection of PM during surgery. However, the role of ICG for patients with GA, and its role during diagnosic laparoscopy (DL), remain unknown.

Tumor bone metastasis refers to the metastasis of malignant tumors to the bone through lymph, blood or direct invasion to generate daughter tumors, which is the most common bone tumor. More than 40% of patients with malignant tumors will have bone metastasis, among which breast cancer, prostate cancer is more common, once the tumor cells occur bone metastasis, it means that the disease enters the advanced stage, posing a serious threat to the life safety of patients, therefore, early diagnosis of various primary malignant tumor bone metastases, can lay the foundation for clinical implementation of effective treatment measures. The laboratory of Hank F. Kung at the University of Pennsylvania has developed a new generation of 68Ga-labeled radiopharmaceutical P15-041 ([68Ga]Ga-HBED-CC-BP) based on existing phosphonate-targeting molecular probes (Figure 1). Data from preclinical studies indicate that P15-041 shows additional advantages in rapid and easy complex formation compared to current [68Ga]Ga-BPAMD, [68Ga]Ga-NO2AP-BP, [68Ga]Ga-DOTA- (ZOL). In vivo experiments, P15-041 showed good bone resorption and rapid renal excretion in normal mice. Haiyan Hong et al. [13] prepared multiple clinical doses of P15-041 and successfully evaluated it in patients, followed by intravenous P15-041, followed by a whole body PET/CT scan. Robert K. Doot et al. conducted dosimetric experiments on P15-041, analyzed the radioactive distribution of the drug in normal organs and the dynamic change of the dose of the drug in the body over time, and the results showed that P15-041 had high uptake in the bladder wall and bone cortex, blood and other tissues cleared quickly, and there was obvious radioactive enrichment in the myocardium in the early stage of imaging, and P15-041 had the potential to become a new generation of excellent phosphonate molecular probes.

The goal of this clinical research study is to learn whether delivering spine radiosurgery in a single large dose is better than delivering spine radiosurgery over 3 smaller doses. Researchers also want to learn about the effects of a single dose on participant's symptoms, pain, and quality-of-life.

This study will see whether collecting and analyzing needle biopsy samples from colon cancer liver metastases (CLM) after a thermal ablation procedure will be able to identify cancer cells that are still alive. The results of these biopsies could help determine the next treatment for your cancer, but the biopsies could cause side effects.

A biomarker is a measurable indicator of the severity or presence of some disease state. In this study, brain metastases patients who will be receiving radiation treatment, will undergo CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) scans prior to and after radiation treatment to measure these biomarkers. This is a single-center phase II study to validate the predictive abilities of biomarkers, in terms of determining how patients will respond to radiation treatment.

PSMA-PET/CT response measurements after LHRH agonist and upfront therapy in men diagnosed with de novo metastasized hormonal sensitive prostate cancer.

The project, called "BALLETT" (Belgian Approach of Local Laboratory Extensive Tumor Testing), has a double goal: (1) show the relevance of broad molecular profiling to improve oncological patients care, (2) demonstrate that broad molecular testing can be performed in a decentralized setting by local diagnostics laboratories in a fully standardized and uniform way while complying with the highest quality standards. This 2-year study involves the consortium of 9 cooperating Belgian NGS laboratories and will enroll 936 metastatic or locally advanced cancer patients coming from 13 different Belgian hospitals and cancer centers. Upon inclusion, all cancer patients will be offered 'comprehensive genomic profiling' (CGP) using Illumina's TSO500 NGS panel. This targeted NGS panel of 523 genes allows for the detection of single nucleotide variants, small indels, copy number variations and fusions, as well as for the determination of the 'tumor mutational burden' (TMB) and the 'microsatellite-instability' status (MSI). Both the wet lab execution of the CGP as well as the biological and clinical classification of the variants will be performed in a fully standardized way among the 9 participating Belgian local NGS laboratories. The CGP results will be interpreted and discussed in the weekly meeting of the BALLETT national molecular tumor board (MTB), composed of oncologists, pathologists, molecular biologists, geneticists and bioinformaticians. The MTB will provide recommendations for targeted or immunotherapy based on the CGP results. Clinical Decision Support platforms OncoKDM (OncoDNA) and Clinical Genomics Workspace (PierianDx), both expert software that turns NGS data into actionable clinical information, will be used. The resulting therapy recommendation may consist of an approved therapy, a clinical trial, a medical need program or off-label use of cancer drugs. Treating physicians will receive the MTB recommendations and decide on the actual management of their patients. Reasons for not following the MTB recommendation will be registered. The objectives of the project are: To evaluate the clinical value of CGP in "real-world" practice in giving patients with advanced/metastatic solid tumours broader access to precision medicine To describe the landscape of genomic alterations and quantify the actionable variants detected by comprehensive panel testing To evaluate the number of actionable variants that would have been missed if the NGS analysis was limited to the reimbursed NGS panel (ComPerMed panel). To assess the technical success of CGP To standardize CGP data analysis, clinical interpretation, therapy recommendation and reporting among participating laboratories to the highest extent possible To describe and to quantify the uptake of treatments and the inclusion in clinical trials recommended by the molecular tumour board guided by the CGP To assess clinical benefit by calculating PFS ratio for individual patients (PFS on CGP-selected therapy/PFS on prior therapy) (null hypothesis: ≤ 15% of patient population has PFS ratio of ≥ 1.3) To work in a multi-stakeholder approach to attract more innovative treatments and clinical trials in Belgium To establish a Belgian genomic tumor database under the authority of the governmental 'Sciensano' thereby increasing public health knowledge in Belgium

This is a multi-arm prospective trial that evaluates the ability of a novel imaging radiolabeled agents to detect metastatic cancer in participants with solid tumors using a gallium 68 (68Ga-) or copper 64 (64Cu-) FAP-2286 tracer. FAP-2286 is a peptidomimetic molecule that that binds to Fibroblast Activation Protein (FAP). FAP is a transmembrane protein expressed on cancer-associated fibroblasts, and has been shown to be present on a number of solid tumors.

The primary research purpose is to evaluate the diagnostic efficacy of 68Ga-PSMA PET in metastatic lesions of locally advanced and advanced renal cell carcinoma, and to compare with that of enhanced CT. The second purpose is to evaluate whether 68Ga-PSMA PET can change the treatment decision of patients with locally advanced and advanced renal cell carcinoma
