What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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.

Summary

This study tests a small device called Seismofit that sticks to the chest and measures heart vibrations to estimate fitness in under three minutes. Researchers want to see if it can predict complications like pneumonia and hospital stay length in 164 oesophageal cancer patients undergoing chemotherapy and surgery. The device is compared to the standard hour-long exercise test to see if it is accurate enough for routine use.

What this could mean

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

Active substance
Seismofit device (a small chest patch that measures heart vibrations to estimate fitness)
What this could lead to
If successful, this could provide a quick, simple way to assess fitness and predict complications in oesophageal cancer patients, helping doctors tailor treatment.
What could go wrong
This is an early-stage study with only 164 participants, and the device has not been tested in this patient group before. It may not accurately predict outcomes or replace standard tests.
