What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study will look at tumor samples from 12 people with esophageal cancer before and after they receive standard chemotherapy plus immunotherapy followed by surgery. Using advanced techniques like single-cell analysis, researchers aim to understand how the tumor environment changes and why some patients respond better. This is an observational study, meaning it does not test a new treatment but gathers information to guide future research.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could reveal why some patients respond better to chemo-immunotherapy, pointing toward more personalized treatments for esophageal cancer.
What could go wrong
This is a very small, early observational study (12 people) that does not test a new treatment. It may not lead to direct patient benefits or apply to all patients.

Participants

About 12 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Jun 2026

An estimate. Start dates often move.

Expected to finish

Dec 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

This study will enroll adults with pathologically confirmed, potentially resectable esophageal squamous cell carcinoma who are scheduled to receive standard neoadjuvant chemotherapy combined with immunotherapy followed by surgery. Participants will be recruited from routine clinical practice at a single center. Tumor tissue will be collected before treatment and again at the time of surgical resection, and peripheral blood samples may also be collected when feasible for translational analyses of tumor microenvironment changes associated with pathological response and clinical outcomes.

Ages

18 to 80 years

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.
