Primary Outcome Measures:
  • acute moist desquamation [ Time Frame: weekly during radiotherapy and 1 month after radiotherapy ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Acute skin toxicity other than moist desquamation [ Time Frame: weekly during radiotherapy and 1 month after radiotherapy ] [ Designated as safety issue: Yes ]
  • Late skin toxicity [ Time Frame: at 6, 12, 18 and 24 months after radiotherapy ] [ Designated as safety issue: Yes ]
  • skin and lung fibrosis assessed with computed tomography [ Time Frame: before radiotherapy and 1 month and 1 year after radiotherapy ] [ Designated as safety issue: Yes ]
  • Quality of life [ Time Frame: at 1 year and 2 years after radiotherpay ] [ Designated as safety issue: No ]
  • dose-volume parameters [ Time Frame: of planning ] [ Designated as safety issue: No ]
  • time of treatment delivery [ Time Frame: daily during radiotherapy ] [ Designated as safety issue: No ]
  • single nucleotide polymorphisms associated with skin toxicity and breast fibrosis [ Time Frame: 1 blood sample before radiotherapy ] [ Designated as safety issue: No ]
