Liposomal Doxorubicin Before Mastectomy in Treating Women With Invasive Breast Cancer

OBJECTIVES:

Primary

• Evaluate the feasibility, safety, and maximum tolerated dose of intraductal pegylated doxorubicin HCl liposome in women with invasive breast cancer awaiting mastectomy.

Secondary

• Determine the pharmacokinetics of intraductal pegylated doxorubicin HCl liposome, including serial plasma concentrations of doxorubicin and doxorubicinol and tissue concentrations in different portions of the breast at the time of surgery.

OUTLINE: This is a dose-escalation study.

Patients receive an intraductal injection of pegylated doxorubicin HCl liposome* on day 1. Patients undergo mastectomy 2-4 weeks later.

Cohorts of 3-6 patients receive escalating doses of pegylated doxorubicin HCl liposome* until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. At least 6 patients are treated at the MTD.

NOTE: *The first cohort of 3 patients receive intraductal dextrose only followed by surgery as a feasibility study. An additional 3 patients receiving intravenous PLD will be enrolled in a pharmacokinetic control portion of the study.

DISEASE CHARACTERISTICS:

• Histologically confirmed infiltrating carcinoma of the breast meeting any of the following criteria:

• T1-3, any N disease
• Proven ductal carcinoma in situ
• Unresected disease

• Planned mastectomy as definitive surgical procedure

• Known or suspected metastatic disease allowed provided mastectomy is planned

• No significant history of severe allergy to iodinated contrast material or debilitating anxiety that may not allow for a ductogram

PRIOR CONCURRENT THERAPY:

• See Disease Characteristics
• Prior preoperative chemotherapy, trastuzumab (Herceptin®), or hormonal therapy allowed provided it was completed 7-14 days prior to study treatment
• No prior radiation therapy, excisional biopsy, breast reduction, areolar surgery, or breast implant (present or past history of implant that was removed)
• No other prior procedure that may have altered the breast ductal system in the ipsilateral breast
