Primary Outcome Measures:
  • Disease free survival [ Time Frame: Patients are followed up for 7 years after initial enrollment (from Oct. 2009 through Oct. 2016). ] [ Designated as safety issue: No ]

    Disease-free survival is defined as the interval from the date of enrollment to the date of any of the following events.

    1. Local recurrence, distant metastasis
    2. Metachronous breast cancer, secondary cancer
    3. Death


Secondary Outcome Measures:
  • Overall survival [ Time Frame: Patients are followed up for 7 years after initial enrollment (from Oct. 2009 through Oct. 2016). ] [ Designated as safety issue: No ]
    Overall survival is defined as the interval from the date of enrollment to the date of death from any cause.

  • Relapse-free survival [ Time Frame: Patients are followed up for 7 years after initial enrollment (from Oct. 2009 through Oct. 2016). ] [ Designated as safety issue: No ]

    Relapse-free survival is defined as the interval from the date of enrollment to the date of any of the following events.

    1. Local recurrence, distant metastasis
    2. Death

  • Percentage of participants with adverse events as a measure of safety [ Time Frame: Evaluations are performed at the time of starting the specified treatment and 2, 3, and 6 month, 1 year, 1 year 6 months, 2 years, 2 years 6 months, and 3 years after the start of treatment. Subsequently, evaluations are done at 1-year intervals. ] [ Designated as safety issue: Yes ]
    The following variables are evaluated: left ventricular ejection fraction, white-cell count, neutrophil count, platelet count, bilirubin level, alanine aminotransferase level, aspartate aminotransferase level, alkaline phosphatase level, and creatinine level.

  • Health-related QOL (HRQOL) [ Time Frame: Evaluations are performed at the time of starting the specified treatment and 2 months, 1 year, and 3 years after the start of treatment. ] [ Designated as safety issue: No ]
    The following QOL questionnaire forms (in Japanese) are used for evaluations: FACT-G, HADS, EQ-5D, and PNQ.

  • Cost effectiveness analysis [ Time Frame: Data on direct medical costs for the 3-year period after the start of the treatment are obtained from CRF. Data on direct nonmedical costs and indirect costs are obtained from questionnaires 2, 12, and 36 months after starting the treatment. ] [ Designated as safety issue: No ]

    Survey items are as follows.

    1. Direct medical costs: medical costs associated with therapy, the management of adverse events, etc.
    2. Direct nonmedical costs: transportation expenses required for medical examinations, costs of health foods, etc.
    3. Indirect costs: work-loss costs associated with treatment that are incurred directly by the patient and by their caregivers
