Trial outcomes

Primary outcomes

1

Ipsilateral breast tumor recurrence

The time from the date of completion of radiotherapy to the date of ipsilateral breast recurrence or death, whichever occurs first. Unit of Measure: Time-to-event (months)

Time frame
From enrollment to the end of treatment at 2 years

Secondary outcomes

1

Early Phase Acute Skin Toxicity

Acute skin toxicity assessed using the Common Terminology Criteria for Adverse Events (CTCAE v5.0), grading severity from Grade 0 (none) to Grade 5 (death). Unit of Measure: CTCAE Grade (0-5)

Time frame
Up to 3 months following completion of radiotherapy
2

Late Phase Breast Fibrosis

Late breast fibrosis assessed using the Common Terminology Criteria for Adverse Events (CTCAE v5.0), grading severity from Grade 0 (none) to Grade 5 (death). Unit of Measure: CTCAE Grade (0-5)

Time frame
From 3 months up to 5 years following completion of radiotherapy
3

Patient Quality of Life (EORTC QLQ-C30)

Quality of life evaluation using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), Chinese Mandarin (Taiwan) version. Scores range from 0 to 100, with higher scores indicating better quality of life. Unit of Measure: Score (0-100)

Time frame
At baseline (before radiotherapy), between 1 week and 1 month following radiotherapy completion, then every 3 to 4 months thereafter until study completion (up to 5 years)
4

Patient Quality of Life (EORTC QLQ-BR23)

Quality of life evaluation using the Breast Cancer Module (BR23) of the European Organization for Research and Treatment of Cancer, Chinese Mandarin (Taiwan) version. Scores range from 0 to 100, with higher scores indicating better quality of life. Unit of Measure: Score (0-100)

Time frame
At baseline (before radiotherapy), between 1 week and 1 month following radiotherapy completion, then every 3 to 4 months thereafter until study completion (up to 5 years)
