Active clinical trials for "Neoplastic Cells, Circulating"

The purpose of this study is to look at the amount of cancer cells in the blood of participants who are being treated with denosumab. The other purpose is to look at how long it takes for cancer to get worse when participants are being treated with denosumab. Circulating tumor cells (CTCs) in the blood of patients with metastatic breast cancer (MBC) have been associated with shorter survival than when CTCs are absent, especially in patients whose cancer has spread to their bones. In this study, we want it see if denosumab (the study drug) will decrease the number of CTCs measured in patients with MBC and cancer that has spread to their bones. We also plan to get blood from participants to study other research markers of interest.

The underlying biology of the various patterns of metastasis observed in different tumour types remains unclear. The detection and characterization of circulating tumour cells in cancer patients has provided important new information about the progression of metastatic events. This information has important implications for cancer prognosis and therapy. This multicenter open-label study is designed as a two-stage three-outcome phase II trial. The aim is to evaluate the efficacy and safety of daily dose of Lapatinib in advanced breast cancer patients with HER-2 non-amplified primary tumours and HER-2 or EGFR positive circulating tumour cells. Evaluation of HER-2 and EGFR status on circulating tumour cells will be performed by the means of the CellSearch equipment (Immunicon, Huntingdon Valley, PA, USA) and FISH method (PathVysion Kit -Abbott Laboratories).

In this monocentric randomized controlled trial, 120 potential non small cell lung cancer (NSCLC) patients for which tissue diagnosis and material for next generation sequencing (NGS) is required for clinical management will be approached the day of their endobronchial ultrasound to participate in the study. They will be randomized to 2 vs 3 passes/lymph node and will all undergo liquid biopsy. The co-primary outcomes are 1)the rate of obtention of adequate material for NGS testing with 2 vs 3 passes/lymph node and 2)the percentage of patients for which liquid biopsy allows to identify clinically pertinent findings not available from tissue biopsy

The role of this transversal study is to assess the specificity and sensitivity of liquid biopsy to detect circulating cells tumor of adenocarcinoma of the ethmoid. Blood sample of participants will be collected at the moment of the surgical procedure or recurrence diagnosis; immediately after surgery; at day 8-10; at month 2-3 of postoperative follow-up. Two comparison groups will be studied: one age and gender-matched group and one professional exposure-matched group to assess the sensitivity and specificity of liquid biopsy

Among biomarkers, CTCs are a convenient, sensitive and biologically informative option. CTC detection could be considered a real-time "liquid biopsy" approach and contains several advantages such as minimally invasive, easy and safe to perform, and multiple samples can be taken over time, better prognosis to indicate an elevated risk of metastases, improved therapy monitoring, providing live disease status information., However, the number of CTCs is very low, so the establishment of cell culture from CTCs becomes the most challenging over the past year. In this study, we develop a short-term CTC expansion protocol combined with a new surface coating technique. Expanded circulating tumor cells will provide genetic information and develop oncology drug screening platform, which provides an opportunity to monitor response to therapy noninvasively.

This trial is a prospective, multicentre, diagnostic study. This study aims to evaluation the early diagnostic ability of circulating tumor cells plus multimodal MRI for prostate cancer.

From literature review, circulating tumor cell was demonstrated its possible role in disease relapse. It was rare nit could be identified in all lung cancer patients. In addition, circulating tumor cell usual aggregate to form circulating tumor micro-emboli and caused distant metastases. Therefore, circulating tumor cell could play a role in detect disease relapse and appropriate treatment could be given more earlier and further prolong patients' survival. However, the detail clinical significance of circulating tumor still remains unknown. The aim of this study was evaluate the clinical significance, including present timing, numbers, and correlation to disease relapse, of circulating tumor cell in lung cancer patients. The investigators want to clarify the clinical significance between circulating tumor cell and clinical presentation of lung cancer in order to establish new prediction model and improve lung cancer patients' survival.

Phase 1 - Optimization Phase: Primary Objective: The primary objective of Phase 1 of this study is to determine the time point at which maximal Circulating Tumor Cell Burden (CTCB) occurs following standard vertebroplasty and Kyphoplasty procedures relative to baseline CTCB. Phase 2 - Comparison Phase: Primary Objective: The primary objective of Phase 2 of this study is to determine the change in CTCB from baseline to post-treatment as measured using the CellSearch™ Assay and to compare the average change between treatment groups with and without the use of the Cavity SpineWand. Secondary Objectives: To determine the change in self-reported pain level from baseline to post-treatment as measured using the visual analogue scale (VAS) for spine pain and to compare the average change in pain level between treatment groups. To determine the change in pain status from baseline to post-treatment as measured using the Brief Pain Inventory (BPI) and to compare the average change in pain status between treatment groups. To determine the change from baseline to post-treatment in the M.D. Anderson Cancer Center Symptom Inventory (MDASI) and to compare the average change between treatment groups. To determine the change from baseline to post-treatment in time to walk a 50-foot distance and to compare the average change between treatment groups.

Proportion of circulating tumor cells (CTC) in the postoperative phase after curative tumor removal of pancreatic cancer will be determined and correlated to the accordance of anesthesia (desflurane versus propofol)

This study will study circulating tumor cell (CTC) release during laparoscopic radical nephrectomy (LRN) for RCC. The main objective is to determine if CTC release can be reduced during RN by using a no-touch technique, with an early renal pedicle ligation. The investigators also aim to describe the CTC profile in terms of CTC count (CTCn), epithelial/mesenchymal status, and CTC cellular features in renal cell carcinoma (RCC) patients, stratified by "primary tumor, regional nodes, metastasis" (TNM) staging, histological subtype, and other clinical and radiological features. Patients undergoing RN will enter a two-arm prospective single-center randomized controlled trial (RCT), comparing a no-touch RN technique, with direct pedicle ligation (Group A) vs. the more conventional approach of kidney traction and manipulation to reach the renal pedicle before its ligation (Group B). A microfluidic size-based CTC isolation device will be used to capture and count CTCs from peripheral blood samples of these patients. CTCs will be identified by staining with antibodies to cytokeratin 8/18, vimentin, 4',6-diamidino-2-phenylindole (DAPI), and cluster of differentiation antigen 45 (CD45). CTC release will be correlated with the disease-free survival (DFS), and overall survival (OS). The investigators will determine if CTC reducing no-touch radical nephrectomy technique improves these hard outcomes.
