About this study

Official title: Risk Criteria Based on MRI Features Outperform Radiographic TNM Staging in Neoadjuvant Treatment Decisions for Patients With Rectal Cancer:A Single-Center, Open-Label, Retrospective, Observational Cohort Study

This study investigates whether risk criteria based on MRI features could identify a cohort of patients with a good prognosis among those recommended for preoperative treatment by NCCN guidelines to avoid preoperative treatment with the likely good survival outcomes by primary surgery and more accurately indicate the response to the treatment and predict prognosis after neoadjuvant treatmen than radiographic TNM staging in the patients who received neoadjuvant therapy.

Read the detailed description

There is a lack of international consensus on the choice of preoperative treatment for patients with rectal cancer. Existing guidelines decide whether to administer preoperative therapy to patients with rectal cancer mainly based on the TNM system developed by AJCC/UICC, however, radiographic TNM staging is unsatisfactory in predicting the prognosis of patients with rectal cancer, due to inflammatory and fibrotic responses TNM re-staging is less accurate than pre-treatment. Studies have shown that high-resolution magnetic resonance imaging(MRI) accurately predicted pathologic findings such as CRM involvement, EMVI and TD and patients with MRI-detected CRM involvement, EMVI and TD are at risk for local and distant recurrence as well as poor overall survival. This retrospective study is designed to was to evaluate whether risk criteria based on MRI features can be used as a basis for neoadjuvant treatment decisions and more accurately indicate the response to the treatment and predict prognosis after neoadjuvant treatment than radiographic TNM staging. Patients with MRI-detected circumferential resection margin (CRM) involvement, extramural venous invasion (EMVI), or tumor deposits (TD) were defined as MRI high-risk.

    Measured: 3 years after the surgery

  2. Local recurrence

    Defined as an intrapelvic recurrence following a primary rectal cancer resection, with or without distal metastasis.

    Measured: 3 years after the surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Rectal 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 7 inclusion and 4 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 8 Nov 2022. 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?

3-year event-free survival rate (time frame: 3 years after the surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 8 Nov 2022.
