About

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Inserting the p53 gene into the tumor may increase the effectiveness of a chemotherapy drug by making tumor cells more sensitive to the drug. Combining chemotherapy with gene therapy may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combining chemotherapy with gene therapy in treating patients who have stage III or stage IV breast cancer.

Full description

OBJECTIVES:

• Determine the therapeutic efficacy of docetaxel, doxorubicin, and Ad5CMV-p53 gene in patients with locally advanced breast cancer.

OUTLINE: Patients receive p53 gene by intralesional injection on days 1 and 2. Patients also receive doxorubicin IV over 15 minutes followed 1 hour later by docetaxel IV over 1 hour on day 1. Treatment repeats every 3 weeks for up to 6 courses. After completion of chemotherapy, patients with a reasonable response undergo surgical resection.

PROJECTED ACCRUAL: A maximum of 60 patients will be accrued for this study.

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
