Caelyx as Primary Treatment for Patients With Breast Cancer and a History of Heart Disease and/or Age Over 65 Years
- Registration Number
- NCT00563953
- Lead Sponsor
- SOLTI Breast Cancer Research Group
- Brief Summary
This is a multicenter study of a primary chemotherapy regimen in breast cancer patients at risk of developing cardiotoxicity. The aim of the study is to evaluate the response rate at surgery.
- Detailed Description
This is a phase II, uncontrolled, open label, multicenter study of a primary chemotherapy regimen consisting of four cycles of liposomal pegylated doxorubicine 35 mg/m² IV plus cyclophosphamide 600 mg/m² on Day 1 every 4 weeks followed by paclitaxel 80 mg/m²/week for 12 weeks before surgery in breast cancer patients at risk of developing anthracycline-induced cardiotoxicity.
Surgery (tumorectomy, quadrantectomy, or mastectomy plus lymphadenectomy) will be performed 2 to 5 weeks after the last primary chemotherapy infusion.
Patients with \> 10% of hormone receptor-positive cells will receive appropriate hormone therapy according to menopausal status.
Patients treated with breast-conserving surgery will receive radiation therapy to the mammary gland.
Patients with T4 tumors or significant axillary involvement (≥ ypN2) will receive radiation therapy to the breast or chest wall and to the lymph node chains.

Group Intervention Description 1 Liposomal pegylated doxorubicine Primary chemotherapy regimen consisting of four cycles of pegylated-liposomal doxorubicine at 35 mg/m² IV plus CPM 600 mg/m² on Day 1 every 4 weeks followed by paclitaxel 80 mg/m²/week for 12 weeks before surgery.
- Primary Outcome Measures
Name Time Method Pathological complete response (pCR). pCR is defined as the absence of invasive cancer in the surgical breast specimen. This definition includes evidence of carcinoma in situ only. At surgery.
- Secondary Outcome Measures
Name Time Method Axillary node involvement after primary chemotherapy. At surgery. Clinical response rate (complete plus partial responses). Clinical response will be assessed by imaging using the WHO criteria. Before and after treatment with paclitaxel. Breast-conserving surgery: tumorectomy or quadrantectomy with or without lymphadenectomy versus mastectomy. At surgery. Left ventricular ejection fraction measured by echocardiography or MUGA. At baseline, every 2 doxorubicine cycles and before surgery. Cardiac sign/symptom questionnaire. At baseline, every 2 doxorubicine cycles and before surgery. Relapse-free survival at 5 years after surgery and overall survival at 5 years after study entry. Until 5 years after surgery.
