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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two minimally invasive techniques for removing lymph nodes under the arm in people with breast cancer that has spread to those nodes. The goal is to see which method better protects nearby nerves, reduces side effects like numbness or pain, and improves recovery and quality of life. Researchers will review medical records from multiple hospitals to analyze outcomes such as nerve function, complications, and long-term cancer control.

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 robotic surgery proves better at protecting nerves and reducing side effects, it could become the preferred minimally invasive option for lymph node removal in breast cancer.
What could go wrong
This is a retrospective study, meaning it looks back at medical records rather than testing treatments head-to-head in a controlled trial. Results may be influenced by unmeasured differences between patient groups.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * pathologically confirmed breast cancer; * clinical N1-N3 stage or confirmation of lymph node metastasis by intraoperative frozen pathology; * Enlarged lymph nodes without significant adhesion to the axillary vessels or nerves; * Ability to comprehend the research questions; * Provision of informed consent and cooperation with the investigation; * No history or current diagnosis of mental illness or impaired consciousness; * ECOG PS 0-1. Exclusion Criteria: * Patients without lymph node metastasis; * Patients who refuse surgery; * Breast cancer patients with cognitive impairment, altered mental status, or inability to clearly express their feelings; * Critically ill patients; * Patients with other malignant tumors or severe medical conditions that render them unable to tolerate surgery.
