About this study
This study aims to evaluate the predictive value of a four-gene methylation assay called Guangzhou Panel in early-stage colorectal cancer. Patients will be divided into two groups: high risk group and low risk group. The primary endpoint is 5 year disease free survival (DFS).
Read the detailed description
The current risk stratification system defined by clinicopathological features does not identify the risk of disease recurrence in patients with early-stage colorectal cancer (CRC) with optimal accuracy. The investigators aimed to investigate whether the epigenetic alterations could serve as novel prognostic biomarkers that would improve the accuracy of the current primary tumor, regional nodes, metastasis (TNM) staging system.
In the current study, the Investigators have analyzed the genome-wide methylation status of cytosine-phosphate-guanosine (CpG) sites using Infinium MethylationEPIC array in primary tumor and adjacent normal samples from 23 recurrent and 22 recurrence-free stage I and II CRC patients to identify potential methylation markers for disease-free survival (DFS). The prognostic value of the candidate biomarkers has been evaluated in a training cohort (n=174) and an independent validation cohort (n=267), and is to be validated in a prospective cohort (estimated n=287).
Comprehensive data analysis identified a subset of methylated CpG loci that associated with a high risk of recurrence. Methylated CpGs in four genes were significantly associated with DFS in multivariate analysis in both training and validation cohort. Moreover, Hypermethylated Genes Counts panel using these four markers showed a higher prognostic value than any clinicopathological factor, current molecular biomarkers or single methylated CpG marker alone in the training and validation cohorts. This four-gene methylation assay is defined as Guangzhou Panel.
The investigators aim to conduct a prospective observational study to evaluate the predictive value of Guangzhou Panel in early-stage colorectal cancer. A total of 287 patients with pathologically verified stage I-II CRC and underwent surgical resection are expected to be recruited in our study. These patients will be divided into high-risk group and low-risk group and will be followed up at least 5 years. The primary endpoint is 5-year disease free survival (DFS). The prognostic strength of candidate biomarkers was adjusted in multivariate Cox regression models including multiple biomarkers and clinicopathologic variables.

Questions about this trial
What is this clinical trial studying?
An observational study of Colorectal Neoplasms, run by Sixth Affiliated Hospital, 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 8 inclusion and 3 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: opening soon, as of the sponsor's last update on 22 Apr 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Yanxin Luo, MD,PhD (+86-13826190263, luoyx25@mail.sysu.edu.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: From date of operation until the date of first recurrence or date of death from any cause, whichever came first, assessed up to 5 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 NCT03923335, which also lists 16 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.
