About this study

This study is a retrospective study of clinical specimens. The study subjects were patients with esophageal cancer who received immunotherapy. Tumor tissue specimens surgically removed from patients before treatment will be collected primarily. In situ immunohistochemistry and multicolor immunofluorescence will be performed. We hypothesize that there are differences in lipid metabolism-related proteins in tumor tissues and immune cells in the preexisting tumor microenvironment in patients with esophageal cancer prior to immunotherapy, and that there is a link between such differences and the efficacy of immunotherapy.

What is being measured

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

  1. Immunotherapy efficacy

    Imaging to assess patient efficacy after cycle 2 immunotherapy (CR/PR, SD/PD according to Recist 1.1)

    Measured: 2018-2022

  2. CR、PR、SD、PD

    CR：All target lesions disappear and the short diameter of all pathologic lymph nodes (both target and non-target nodes) must be reduced to <10 mm.

    PR：At least 30% reduction in the sum of target lesion diameters from baseline levels SD：A relative increase in diameter sum of at least 20% (or the baseline value if the baseline measurement is minimal), referenced to the minimum of the sum of the diameters of all measured target lesions throughout the course of the experimental study; in addition to this, an increase in the absolute value of diameter sum of at least 5 mm must be met (the presence of one or more new lesions is also considered to be disease progression).

    Translated with www.DeepL.com/Translator (free version) PD：The target lesion did not decrease to the level of PR, nor did it increase to the level of PD, and in between, the minimum value of the sum of the diameters can be used as a reference for the study.

    Measured: 2018-2022

Questions about this trial

What is this clinical trial studying?

An observational study of Esophageal Cancer, run by Renmin Hospital of Wuhan 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 4 inclusion and 5 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 26 Jan 2024. 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?

Immunotherapy efficacy (time frame: 2018-2022). The study lists 2 primary outcomes in all. 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 NCT06219031, which also lists 14 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 Jan 2024.
