Brief Summary: RATIONALE Drugs used in chemotherapy such as methotrexate cyclophosphamide and liposomal doxorubicin work in different ways to stop the growth of tumor cells either by killing the cells or by stopping them from dividing Giving chemotherapy after surgery may kill any tumor cells that remain after surgery It is not yet known whether giving liposomal doxorubicin after surgery is more effective than observation or cyclophosphamide and methotrexate in treating breast cancer
PURPOSE This randomized phase III trial is studying liposomal doxorubicin to see how well it works compared with observation or cyclophosphamide and methotrexate in treating older women who have undergone surgery for breast cancer
Detailed Description: OBJECTIVES
Primary
Compare the breast cancer-free interval in elderly women with resectable hormone receptor-negative breast cancer treated with pegylated doxorubicin hydrochloride liposome PDL vs observation or PDL vs cyclophosphamide and methotrexate
Secondary
Compare the tolerability of these regimens in these patients Compare the safety and toxic effects of these regimens in these patients Compare the overall and progression-free survival of patients treated with these regimens Compare the quality of life of patients treated with these regimens Compare the sites of failure in patients treated with these regimens Compare the competing causes of death in patients treated with these regimens Compare the rate of second non-breast malignancy in patients treated with these regimens
OUTLINE This is a randomized multicenter study Patients are stratified according to participating center Patients are assigned based on patient preference to 1 of 2 treatment groups
Group 1 Patients are randomized to 1 of 2 arms arms I and II
Arm I Patients receive pegylated doxorubicin hydrochloride liposome PDL IV over 1 hour on day 1 Treatment repeats every 2 weeks for 8 courses in the absence of disease progression or unacceptable toxicity Arm II Patients undergo observation only Group 2 Patients are randomized to 1 of 2 treatment arms arms III and IV
Arm III Patients receive PDL as in arm I Arm IV Patients receive oral cyclophosphamide once daily on days 1-7 and oral methotrexate twice daily on days 1 and 4 Treatment repeats every week for 16 courses in the absence of disease progression or unacceptable toxicity
All patients may undergo radiotherapy according to institutional standards either during surgery or after the completion of chemotherapy
Quality of life is assessed at baseline and at 3 6 and 12 months
After completion of study treatment patients are followed periodically for 1 year
PROJECTED ACCRUAL A total of 1296 patients will be accrued for this study
