Patient case: 56-year-old female with breast cancer; genetic feature: ERBB2

Clinical trial: Pegylated Liposomal Doxorubicin Hydrochloride and Carboplatin Followed by Surgery and Paclitaxel in Treating Patients With Triple Negative Stage II-III Breast Cancer

Summary: This phase II trial studies how well pegylated liposomal doxorubicin hydrochloride and carboplatin followed by surgery and paclitaxel work in treating patients with stage II-III breast cancer that does not have estrogen receptors, progesterone receptors, or large amounts of human epidermal growth factor receptor 2 (HER2)/neu protein (triple negative). Drugs used in chemotherapy, such as pegylated liposomal doxorubicin hydrochloride, carboplatin, and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving pegylated liposomal doxorubicin hydrochloride and carboplatin before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving pegylated liposomal doxorubicin hydrochloride and carboplatin followed by surgery and paclitaxel may be an effective treatment for breast cancer.

Detailed description: PRIMARY OBJECTIVES:
  I. To determine the rate of pathologic complete response with treatment of liposomal doxorubicin (pegylated liposomal doxorubicin hydrochloride) and carboplatin in patients with estrogen receptor (ER), progesterone receptor (PR), HER2 negative breast cancer (triple negative breast cancer [TNBC]).
  SECONDARY OBJECTIVES:
  I. To determine the recurrence free survival (RFS), 2-year RFS, and overall survival (OS) after treatment with neoadjuvant liposomal doxorubicin and carboplatin followed by definitive breast surgery and then weekly paclitaxel in patients with ER, progesterone receptor (PgR), HER2 negative breast cancer.
  II. To describe the mutational spectrum of tumors found in primary, untreated ER, PgR, HER2 negative breast cancer and their association with pathologic complete response to neoadjuvant pegylated liposomal doxorubicin hydrochloride (doxil) and carboplatin.
  III. To determine functional significance of genomic landscape in predicting drug response using patient derived xenograft (PDX) and ex vivo models.
  OUTLINE:
  NEOADJUVANT: Patients receive pegylated liposomal doxorubicin hydrochloride* intravenously (IV) over 90 minutes and carboplatin IV over 30-60 minutes on day 1. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity.
  ADJUVANT: Patients undergo definitive surgery at the discretion of the treating physician. Patients then receive paclitaxel IV over 60 minutes once weekly for 12 weeks in the absence of disease progression or unacceptable toxicity.
  *NOTE: If there is a shortage of pegylated liposomal doxorubicin hydrochloride, patients receive epirubicin hydrochloride IV over 15-20 minutes on day 1.
  After completion of study treatment, patients are followed up every 6 months for up to 20 years.

  -  Patients must be eligible to undergo surgery, either lumpectomy or mastectomy for local treatment of the breast cancer; surgical margins at discretion of surgeon per National Comprehensive Cancer Network (NCCN) guidelines; axillary exploration at discretion of surgeon but all patients minimally have sentinel lymph node evaluation at time of surgery
