About this study
Official title: Circulating Tumor DNA as a Prognostic Marker for Postoperative Relapse in Early and Intermediate Stage Colorectal Cancer:A Prospective, Multicenter,Observational, Single-Blinded Controlled Study
By monitoring the serum ctDNA mutational profile using NGS, the present clinical trial aims to elucidate the correlation between the postoperative ctDNA status and the prognosis of patients with early and intermediate-stage colorectal cancer, and explore the possibility of clinical utility of serum ctDNA as a clinical index to predict postoperative relapse.
Read the detailed description
Colorectal cancer (CRC), as one of the common malignant tumors with high mobidity and mortality, is a major health threat in China.Surgical resection is the conventional treatment for early and intermediate stageCRC, however, it is not curative and postoperative recurrenceremains a clinical dilemma.Early detection of recurrence by serum tumor biomarkers and Computed Tomography (CT) during follow-up can improve the overall survival of patients with surgical resection. Nevertheless, thecurrently available tumor biomarkers have limited sensitivity and specificity, and CT is associated with radiation exposure. Therefore, there is a need for a more effective and feasible methodfor the prediction of postoperative recurrence.
Circulating tumor DNA (ctDNA) is tumor-derived fragmented DNA with an average size of 170bp, mixed with cell free DNA (cfDNA) of other sources in blood circulation. Although the mechanisms of its release have not been fully addressed, apoptosis and/or necrosis of tumor cells and serum exosome are considered as its main source, which makes it a genomic reservoir of different tumor clones. Also, as its half-life is up to hours, ctDNA is reflecting the most up-to-date status of tumor genome. Hence, it allows for noninvasive molecular characterization of tumors,which can be qualitative, quantitative and used for disease monitoring.
The possibility of that ctDNA could be used to detect micrometastatic disease in patients received surgical resection was suggested in several studies. UsingNext Generation Sequencing (NGS),Newman et al. have shown that the serum level of ctDNA was correlated withtumor progress and prognosis in NSCLC. Isaac et al. demonstrated the postoperativectDNA level was associated with breast cancer progression, and it was more sensitive compared to CT scan for predicting the early relapse. Tie et al. examined the postoperative ctDNA level of 1046 plasma samples from a prospective cohort of 230 patients with resected stage II CRC by NGS, and their results demonstrated that recurrence happened in 79% of the patients with positive postoperative ctDNA at median follow-up of 27 months, versus 9.8% in the negative postoperative ctDNA group.
By monitoring the serum ctDNA mutational profile using NGS, the present clinical trial aims to elucidate the correlation between the postoperative ctDNA status and the prognosis of patients with early and intermediate-stage colorectal cancer, and explore the possibility of clinical utility of serum ctDNA as a clinical index to predict postoperative relapse.

Questions about this trial
What is this clinical trial studying?
An observational study of Colorectal Cancer, run by Sun Yat-sen University 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 6 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 26 Feb 2019. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Feng Wang, MD.,PhD. (+862087343795, wangfeng@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Disease Free Survival (time frame: through study completion, an average of 2 years). 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 NCT03312374, which also lists 6 linked publications.
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 26 Feb 2019.
