About this study

The goal of this multicenter retrospective cohort study is to evaluate the impact of different pathological regression types on survival and recurrence patterns, with a particular focus on ypT0N+ patients in patients with esophageal squamous cell carcinoma. The main questions it aims to answer are the survival and recurrence patterns among the different pathological regression types in patients with esophageal squamous cell carcinoma after neoadjuvant chemoradiotherapy.

Questions about this trial

What is this clinical trial studying?

An observational study of Esophageal Squamous Cell Carcinoma, run by Tianjin Medical University Cancer Institute and Hospital.

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 1 inclusion and 1 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 5 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

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?

Overall survival (time frame: From date of surgery until the date of death from any cause or last follow-up, assessed up to 10 years.). 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 5 Feb 2024.
