Trial summary

Neoadjuvant therapy has been widely applied to locally advanced rectal cancer. However, about 50% of patients receiving this therapy do not respond well as evidenced by the fact that their T or N stages are not effectively decreased judged by postoperative pathological examination.

About this study

Official title: Identification of Tissue Biomarkers for Predicting Neoadjuvant Chemoradio-resistance in Patients With Middle-low Local Advanced Rectal Cancer.

Neoadjuvant therapy has been widely applied to locally advanced rectal cancer. However, about 50% of patients receiving this therapy do not respond well as evidenced by the fact that their T or N stages are not effectively decreased judged by postoperative pathological examination. The purpose of this trail is to identify the biomarkers (from within patients' tumor mass before neoadjuvant therapy) to predict resistance to neoadjuvant therapy. These biomarkers can help stratify neoadjuvant-resistant patients towards surgery while avoiding unnecessary chemoradio-based neoadjuvant therapy.

Read the detailed description

According to postoperative pathological examination results, all participants will be divided into two groups: complete response (ypT0N0) and poor response (>ypT1-2N0). Differentially expressed genes between complete response and poor response will be analyzed. A scoring formula will be established based on the results. Tumor tissue samples are collected before neoadjuvant therapy and will be analyzed via RNA sequencing.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT03573791
Study groupRoleWhat they receive
Complete responseAfter neoadjuvant therapy, postoperative pathological examination will be performed to evaluate the efficacy of the therapy. Define postoperative staging ypT0N0 as complete response.
Poor responseAfter neoadjuvant therapy, postoperative pathological examination will be performed to evaluate the efficacy of the therapy. Define postoperative staging >ypT1-2N0 as poor response.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparing gene expression differences between poor response group and complete response group by using RNA sequencing.

    Using RNA-seq sequencing method to obtain the whole genome transcription profiles of the poor response group and complete response group, and compare the gene expression differences between these two groups.

    Measured: 6 months

Secondary outcomes (2)
  1. Overall survival(OS)

    The total survival time of the participants from joining the group to the death. If the death time is unknown, the relevant participants will be excluded for analysis.

    Measured: 3 years

  2. Progression Free Survival(PFS)

    The time period that from participants joining the groups to the progression of disease(recurrence or metastasis) or death of any cause.

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Rectal Cancer and Cancer of Rectum, run by Union Hospital, Tongji Medical College, Huazhong University of Science and Technology at 2 sites 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 5 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: looking for participants now, as of the sponsor's last update on 18 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 Zheng Wang, MD/PhD (+86 27 85726612, zhengwang@hust.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Comparing gene expression differences between poor response group and complete response group by using RNA sequencing. (time frame: 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 NCT03573791, 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 18 Aug 2026.
