Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Breast cancer is the leading type of cancer in women worldwide. Although advances in treatment have led to an overall reduction in breast cancer mortality, survivors continue to have an ongoing risk of disease recurrence. For women who experience breast recurrence, mastectomy has historically been the only treatment approach offered. However, it has been associated with negative health outcomes, including reduced quality of life, depression and anxiety, and impaired sexual functioning. As a result, there is increasing interest to identify treatment options that include breast preservation. Breast-conserving surgery followed by re-irradiation with partial breast irradiation has recently been found to be a safe alternative to mastectomy for women who have undergone prior whole breast radiation.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Treatment related toxicity
Time Frame: 12 months
determine the toxicity of partial breast re-irradiation (PBrI) as rate of grade ≥ 3 treatment-related skin, fibrosis, and breast pain Adverse Events, accordin to Common Terminology Criteria for Adverse Events scale 5.0 (Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild AE, Grade 2 Moderate AE, Grade 3 Severe AE, Grade 4 Life-threatening or disabling AE, Grade 5 Death related to AE) up to 1 year from completion of radiation treatment
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
To evaluate distant-metastasis free survival
Time Frame: 5 years
Distant metastasis-free survival is defined as time from registration to the appearance of a distant metastasis confirmed radiographically and/or pathologically or death from any cause
5 years
in-breast recurrence in the ipsilateral breast
Time Frame: 5 years
In-breast recurrence is defined histologic evidence of recurrent carcinoma, invasive or noninvasive (excluding lobular carcinoma in situ), in the ipsilateral breast
5 years
Number of patients free from mastectomy over total number of patients
Time Frame: 5 years
Freedom from mastectomy is calculated from mastectomy failure rates. Failure is a mastectomy of the treated breast performed for any reason
5 years
Overall survival
Time Frame: 5 years
Overall survival is defined as time from registration to date of death or last follow-up
5 years
Patient satisfaction
Time Frame: 5 years
Patients satisfaction is assessed with the Breast-Q questionnaire (from 0 (worst) to 100 (best). Higher scores reflect a better outcome)
