Clinical Trial Summary

Radiotherapy has been confirmed as an important treatment breast-conserving surgery reducing the risk of any recurrence of breast cancer and breast cancer-related mortality in patients with early breast cancer.

There are no comparative data on the ideal radiotherapy treatment regimen for patients with early stage breast cancer who underwent conservative surgery in the Brazilian population.

Description:

The investigators propose a prospective, randomized, pilot study, with active control, to evaluate the viability and safety of accelerated partial breast irradiation, in 5 fractions, comparing with the radiotherapy regimens of the whole breast in 15 and 5 fractions, in patients with breast cancer, in initial stage, who underwent conservative surgery.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rate of local recurrence	To estimate and compare the rate of local recurrence between the experimental and control arms.	5 years
Secondary	Time to occurrence of distant metastases	Distant tumor time is defined as number of days from randomization until occurrence of distant metastases, death without prior distant progression, or end of follow-up.	5 years
Secondary	Disease-free survival	Disease-free survival, defined as number of days from randomization until the first occurrence of local recurrence, distant metastases, tumor-related death, death without prior progression, or end of follow-up.	5 years
Secondary	Overall survival	Overall survival time, defined as number of days from randomization until death or end of follow-up.	5 years
Secondary	Medico-economic study	To evaluate and compared the cost between Accelerated Partial Breast Irradiation with Standard and Hypofractionated irradiation	Baseline and 3 months, 6 months, 12 months, 2 years, 5 years after treatment end
Secondary	Health-related Quality of Life	To evaluate the patients quality of life with the help of the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30). This questionnaire was designed to be cancer specific, multidimensional in structure, suitable for self-administration (brief and easy to complete), and applicable in a wide range of cultural contexts. The scores in each dimension are uniformly transformed to dimensions ranging from 0 to 100, with 0 denoting the negative (low functioning, high symptom burden) and 100 the positive end (high functioning, low symptom burden) of the continuum.	Baseline and 3 months, 6 months, 12 months, 2 years, 5 years after treatment end
Secondary	Evaluation of quality of life change by European Organization for Research and Treatment of Cancer Breast-Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-BR23)	To evaluate the patient quality of life with the help of the European Organization for Research and Treatment of Cancer Breast-Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-BR23). The 23-item EORTC QLQ BR23 contains two breast cancer specific functional scales (body image and sexuality) and three symptom scales evaluating arm symptoms, breast symptoms, and systemic therapy symptoms. The minimum and maximum values are 0 and 100, and higher scores mean a better outcome.	Baseline and 3 months, 6 months, 12 months, 2 years, 5 years after treatment end
Secondary	Fatigue Questionnaire (Functional Assessment of Cancer Therapy-Fatigue - FACT-F)	To evaluate the patient quality of life with the help of the Functional Assessment of Cancer Therapy-Fatigue (FACT-F). Scores are interpreted according to the guidelines of the Scoring Manual. The higher the number of points, the better the quality of life. To obtain the score, the negative questions are reverted; then the answers of the domains are added up, and a proportional average is carried out in case of non answered items.	Baseline and 3 months, 6 months, 12 months, 2 years, 5 years after treatment end
Secondary	Measurement Satisfaction of Body Image of the participants	To evaluate the patient quality of life and patient satisfaction with the help of the Body Image Scale (BIS). Scores are interpreted according to the guidelines of the Scoring Manual. The Body Image Scale (BIS) is a self-assessment scale designed to assess cancer patients' perceptions of their appearance and identify any changes to those perceptions resulting from a disease or a treatment. The total score ranges from 0 to 30. A higher score means a higher level of body image disturbance.	Baseline and 3 months, 6 months, 12 months, 2 years, 5 years after treatment end
Secondary	Changes in anxiety and depression	To evaluate the patient quality of life and patient satisfaction with the help of the Hospital Anxiety and Depression Scale (HADS). Scores for each sub scale (depression and anxiety) are summed-up and range from 0 to 21. Values from 0-7 indicate normal levels, 8-10 are border values and values from 11-21 are considered to be pathological.	Baseline and 3 months, 6 months, 12 months, 2 years, 5 years after treatment end
Secondary	Early and late adverse effects in normal tissues	To evaluate the results reported by patient and evaluated by doctors, as well as, photographic assessments.	5 years
Secondary	Late adverse effects	To evaluate if the patient had symptoms of swelling or edema in the arm, breast shrinkage, hardness, pigmentation, necrosis, pain and tenderness in the breast.	5 years
Secondary	Acute toxicity rate	To evaluate acute toxicity rate. The maximum grade for acute toxicity will be recorded for each patient at each treatment evaluation using Common Terminology Criteria for Adverse Events.	5 years
