Doxorubicin Hydrochloride Liposome in Treating Women With Ductal Carcinoma in Situ Undergoing Surgery

OBJECTIVES:

To demonstrate the efficacy and safety of neoadjuvant intraductal pegylated liposomal doxorubicin hydrochloride in women with ductal breast carcinoma in situ undergoing surgery.
To demonstrate the ability to identify and cannulate the duct demonstrating precancerous disease in these women.
To integrate the Humboldt Community Breast Health Project into the planning and execution of this study.

OUTLINE: Patients undergo identification of the intraductal lesions via cannulization. Patients receive pegylated liposomal doxorubicin hydrochloride (PLD) intraductally through the inserted cannula. Some patients are randomized to receive saline instead of PLD. Within 4-6 weeks, all patients undergo surgery.

Patients undergo tissue and ductal fluid sample collection at baseline and at surgery for correlative laboratory studies. Tissue samples are assessed for histomorphology, proliferation (Ki67), cell death (apoptosis index), genetic markers, necrosis, inflammation, and loss of heterozygosity by HE stain, IHC, TUNEL, and PCR. Nipple aspirate and ductal lavage fluid samples are analyzed for cytomorphology (cellular atypia), proliferation (Ki67), cell death (TUNEL), differentiation (G-actin), and genetic markers (FISH) by quantitative fluorescence image analysis. Samples are also analyzed for bFGF and CEA by ELISA, and methylation by PCR.

After completion of study therapy, patients are followed every 6 months for at least 2 years.
