Trial summary

Circulating tumor cells (CTCs) have the potential to provide a surrogate for'real-time biopsy' of tumor biological activity. Enumeration and molecular characterization of CTCs in breast cancer could play an important role in diagnosis, predicting the risk for tumor recurrence, and providing novel target therapy… Read more about this study

About this study

Circulating tumor cells (CTCs) have the potential to provide a surrogate for'real-time biopsy' of tumor biological activity. Enumeration and molecular characterization of CTCs in breast cancer could play an important role in diagnosis, predicting the risk for tumor recurrence, and providing novel target therapy biomarkers. In view of these facts, the investigators wanted to demonstrate the value of multiparameter flow cytometry in detecting human tumor cells of breast cancer in normal peripheral blood after cryosurgery with or without dendritic cell(DC)-cytokine-induced killers(CIK) treatment, and the investigators also compared the specificity with reverse transcriptase polymerase chain reaction (RT-PCR) method.

Read the detailed description

1 day before and 2 days after cryosurgery with or without DC-CIK treatment,approximately 17-mL ethylene diamine tetraacetic acid(EDTA)-blood was drawn by vein puncture from patients with breast cancer and healthy volunteers. The blood of the healthy volunteers will be used to evaluate the sensitivity and specificity and as negative control cells. To avoid contamination with skin cells, 2 mL blood will be discarded before the study samples will be taken.Briefly, the mononucleate cells will be separated from the blood over Ficoll- Paque for 20 min with 1800g at 4℃. The interface cells will be removed and washed, and the red blood cells(RBCs) will be removed using a lysis buffer followed by a repeated wash. The mononuclear cells will be counted and aliquot for RT-PCR and multiparameter flow cytometry on the basis of at least 2-3×106 cells for each methodology. The cell pellet will be resuspended in phosphate-buffered saline for multiparameter flow cytometry and in Trizol reagent for RT-PCR. Aim : Identification of CTCs may lead to better diagnosis and prognosis and could help to choose an adequate therapy.

Questions about this trial

What is this clinical trial studying?

An observational study of Neoplastic Cells, Circulating, run by Fuda Cancer Hospital, Guangzhou at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The number of Circulating Tumor Cells (CTCs) (time frame: Up to 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02450357, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Dec 2015.
