To Compare Treatment With Doxorubicin or Capecitabine for Metastatic Breast Cancer in Women 60 Years and Older

• Time to disease progression [ Time Frame: Up to disease progression or death ] [ Designated as safety issue: No ]
  Time to disease progression is the duration in months from the date of randomization to the first documented evidence of disease progression or death caused by disease progression before the end of study. Time to disease progression will be compared between patients treated with doxorubicin and capecitabine.
  
  

• Overall Response rate [ Time Frame: Up to disease progression or death ] [ Designated as safety issue: No ]
  Overall response rate is measured as the number of patient with complete and partial responses. It will be compared between patients treated with doxorubicin and capecitabine.
  
  
• Overall survival [ Time Frame: Up to 2 years after last patient is enrolled or death ] [ Designated as safety issue: Yes ]
  Overall survival is the duration from date of randomization to the date of death due to any cause during the study. It will be compared between patients treated with doxorubicin and capecitabine.
  
  
• Number of patients with adverse events [ Time Frame: Up to 1 month after intake of last dose of study medication ] [ Designated as safety issue: Yes ]
  Safety evaluated as "number of patients with adverse events" is compared between 2 treatment groups (doxorubicin and capecitabine).
  
  
• The European Organization for Research and Treatment of Cancer (EORTC) QLQ (Quality of Life Questionnaire) - C30 [ Time Frame: Day 1 and end of treatment ] [ Designated as safety issue: No ]
  The 30 item questionnaire to assess quality of life incorporates five functional scales: general physical symptoms, physical functioning, psychological distress, social functioning, and fatigue/malaise. Most items are rated on a 4 point Likert scale ranging from 0 = "not at all" to 4 = "very much". The effect of doxorubicin and capecitabine on the quality of life measured by the EORTC QLQ-C30 is assessed.
  
  
• Subjective Significance Questionnaire (SSQ) [ Time Frame: Day 1 and end of treatment ] [ Designated as safety issue: No ]
  The SSQ consists of 4 items in which patients rate the degree to which they experienced an improvement or deterioration in their physical condition, emotional state, ability to enjoy their social life, and overall quality of life since there last QOL assessment.Each of the four items are rated on a 7 point Likert scale ranging from 0 = "very much worse" to 7 = "very much better". The effect of doxorubicin and capecitabine on the quality of life measured by the SSQ is assessed.
  
  

This is an open-label (all people know the identity of the intervention), randomized (the study medication is assigned by chance), multicenter study comparing with pegylated liposomal doxorubicin (PLD) with capecitabine as first line chemotherapy of metastatic breast cancer in women 60 years and older. The study consists of a screening Phase (up to 14 days prior to treatment), treatment phase (up to 1 year), and post-treatment follow-up phase. The planned duration of treatment was 1 year in the absence of disease progression or unacceptable toxicity. Approximately 300 patients will be enrolled and randomly assigned to receive 1 of 2 treatment groups (PLD or capecitabine). Safety evaluations will consist of vital sign examination, physical examination, incidence and severity of adverse events, and laboratory tests findings and will be followed throughout the study.
