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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether tiny particles called exosomes, released by breast cancer cells, contain genetic material (microRNA) that can predict how well chemotherapy will work before surgery. Researchers will collect tumor tissue and blood samples from 60 women with breast cancer and compare the microRNA patterns to whether the cancer completely disappears after treatment. If successful, this could lead to a simple test that helps doctors personalize chemotherapy, avoiding ineffective treatments.

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 lead to a simple blood test that helps doctors choose the best chemotherapy for each breast cancer patient.
What could go wrong
This is an early observational study with only 60 participants, so results may not apply to all patients. The microRNA signature may not reliably predict response.

Who can take part

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

Who is studied

Female patients aged 18 years or older will be enrolled into two cohorts: 1. patients with histologically confirmed breast cancer who are scheduled to receive neoadjuvant chemotherapy, and 2. patients with histologically confirmed benign breast disease. Participants will be recruited from multiple clinical centers. Only leftover tumor tissue and serum samples obtained during routine diagnostic or therapeutic procedures will be used for exosomal microRNA analysis.

Ages

18 years and older

Sex

Female participants only

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Inclusion Criteria: * Female patients aged 18 years or older * Histologically confirmed locally advanced breast cancer scheduled to receive neoadjuvant chemotherapy * Availability of residual tumor tissue and/or serum samples obtained during routine clinical care * Ability to provide written informed consent Exclusion Criteria: * Male sex * Age under 18 years * Prior systemic chemotherapy or radiotherapy administered for the current breast disease before enrollment. * Evidence of metastatic disease at diagnosis (for breast cancer cohort) * Pregnancy or breastfeeding * Any condition that precludes the availability or adequate quality of tissue or blood samples for research purposes
