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

During the study, the patients would undergo radiation of 5.2Gy for 5 fractions to the prophylactic radiation volumes and and a 6Gy per-fraction simultaneous boost to the tumor bed or other high-risk volumes. Acute toxicity of grade 2 or higher in the following 12 weeks after radiotherapy is the primary end point.

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
The rate of patients who develop radiation-associated acute toxicity (≥ 2 degree)
Time Frame: until 12 weeks from the completion of postoperative radiotherapy
The investigators will record the incidence of ≥ 2 degree radiation-associated acute toxicity, such as breast or chest wall oedema, acute dermatitis, breast pain,itch of breast skin; ≥ 3 degree radiation-associated esophagitis; ≥ 3 degree radiation-associated lymphopenia.
until 12 weeks from the completion of postoperative radiotherapy

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.
