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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 tests a new, ultra-short radiation schedule for early-stage breast cancer. Instead of the usual 3 weeks, patients receive 5 radiation sessions over one week, with an extra boost to the tumor site given at the same time. The goal is to see if this approach is safe, reduces side effects, and keeps the cancer from coming back. The study involves 90 women aged 50 and older who have had breast-conserving surgery.

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.

In order to participate in this study a subject must meet all of the eligibility criteria outlined below. Inclusion Criteria: * Willing and able to provide written informed consent obtained to participate in the study and HIPAA authorization for release of personal health information. * Women ≥ 50 years of age with confirmed de novo invasive carcinoma of breast or ductal carcinoma in situ. * Subjects with completed breast-conserving surgery (BCS) with or without sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND). * Subjects planned to receive either SOC whole breast 3D conformal radiation therapy (3D CRT) or SOC whole breast intensity modulated radiation therapy (IMRT) with standard dose tumor bed boost. * Subjects with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial, per the discretion of the treating radiation oncologist. * Enrollment in another clinical trial is allowed if there is no interference with interventions on this trial per discretion of the Principal Investigator. Exclusion Criteria: * Receipt of concurrent breast reduction involving tissue rearrangement in the lumpectomy cavity (so that boost cannot be accurately targeted). * Synchronous bilateral breast cancer requiring bilateral radiation therapy. * Clinical or imaging evidence of distant metastases. * Prior ipsilateral breast or thoracic radiation. * Autoimmune conditions * Collagen Vascular Disease (such as systemic lupus erythematosus, scleroderma, dermatomyositis, among others) * Patients with pT4 tumors. * Patients recommended to receive regional nodal irradiation with associated radiation risks
