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

Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early

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.

Summary

This study looks at whether artificial intelligence can accurately determine the depth of early esophageal cancer from endoscopic images. Researchers will review past records and images from 890 patients who had their tumors removed. The goal is to see if AI can help doctors decide who needs additional surgery after the initial procedure.
