Paclitaxel, Cyclophosphamide & Doxorubicin, Autologous Dendritic Cells & Surgery in Stage II/III Breast Cancer (Women)

RATIONALE: Drugs used in chemotherapy, such as paclitaxel, cyclophosphamide, and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Injecting the patient's dendritic cells directly into the tumor may stimulate the immune system and stop tumor cells from growing. Radiation therapy uses high-energy x-rays to kill tumor cells. Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the use of estrogen by the tumor cells. Giving combination chemotherapy together with autologous dendritic cells before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving radiation therapy and hormone therapy after surgery may kill any tumor cells that remain after surgery.

PURPOSE: This phase II trial is studying the side effects and how well giving paclitaxel together with cyclophosphamide and doxorubicin followed by autologous dendritic cells and surgery with or without radiation therapy and/or hormone therapy works in treating women with stage II or stage III breast cancer.

About this study

OBJECTIVES:

  • Assess the safety of intratumoral (IT) autologous dendritic cell (DC) injection in women with stage II or III breast cancer receiving neoadjuvant paclitaxel, cyclophosphamide, and doxorubicin hydrochloride followed by surgery with or without adjuvant radiotherapy and/or hormone therapy.
  • Determine the clinical and pathologic response in patients treated with this regimen.
  • Determine the immune response, in terms of tumor cell apoptosis and the presence and characterization of tumor infiltrating white blood cells in resected breast cancer, in patients treated with this regimen.
  • Determine if IT DC injections administered during neoadjuvant chemotherapy-induced tumor cell apoptosis can induce T-cell responses to tumor antigens in these patients.

OUTLINE: This is an open-label study.

  • Leukapheresis: Patients undergo leukapheresis at baseline to collect peripheral blood mononuclear cells for dendritic cell (DC) culture.
  • Neoadjuvant, dose-dense chemotherapy: Patients receive paclitaxel IV over at least 3 hours on day 1 and filgrastim (G-CSF) subcutaneously (SC) on days 4-14 or pegfilgrastim SC on day 2. Treatment repeats every 2 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.

Beginning 2 weeks after completion of paclitaxel chemotherapy, patients receive cyclophosphamide IV and doxorubicin hydrochloride IV on day 1 and G-CSF SC on days 4-14 or pegfilgrastim SC on day 2. Treatment repeats every 2 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.

  • Intratumoral injection of autologous DCs: Intratumoral autologous DCs are injected into the primary breast mass or palpable axillary node on day 7 of the 1st, 2nd, and 3rd courses of paclitaxel chemotherapy. If no tumor can be localized by ultrasound after a course of chemotherapy, the DCs are then injected into the site of the tumor bed previously localized by clip or marker. In the event that the previously injected primary tumor cannot be localized by ultrasound, a palpable lymph node, if still present, should be injected rather than the tissue next to the primary tumor clip or marker.
  • Definitive breast surgery: Within 2-4 weeks after completion of neoadjuvant chemotherapy, patients undergo modified radical mastectomy or lumpectomy with or without standard axillary node dissection.* NOTE: *Standard axillary node dissection is only required if no node assessment was done prior to chemotherapy or if the pre-chemotherapy sentinel node was positive.
  • Radiotherapy: Patients undergoing lumpectomy or those with residual disease requiring chest wall radiotherapy after mastectomy (e.g., T3 or T4 breast lesions or 4 or more axillary lymph nodes) undergo radiotherapy 2-4 weeks after surgery.
  • Hormone therapy: Patients with estrogen and/or progesterone receptor-positive tumors receive adjuvant hormone therapy for ≥ 5 years. Premenopausal patients receive tamoxifen citrate and post- or perimenopausal patients receive either tamoxifen citrate or an aromatase inhibitor (AI), or both of these drugs in sequence, as determined by the treating oncologist.

Peripheral blood samples are obtained during each DC injection, at staging/biopsy, and then periodically for up to 2 years. Blood samples are analyzed by ELISPOT and ELISA assays for evaluation of immune response.

Tumor tissue is obtained by core biopsy of the breast primary and/or palpable axillary lymph node at baseline and again after completion of paclitaxel chemotherapy. Tumor tissue is analyzed by IHC and RT-PCR for COX-2 and VEGF-A and -C expression levels, as well as T-cell and DC infiltration of the tumor. T-cell and DC infiltration is evaluated for correlation with clinical outcomes at diagnosis, at the midpoint biopsy following paclitaxel chemotherapy, and at definitive surgery.

After completion of study therapy, patients are followed periodically for up to 2 years.

Procedure

Hormone manipulation Adjuvant hormone therapy for patients having tumors with estrogen and/or progesterone receptors. Premenopausal patients will be treated with tamoxifen. Post or perimenopausal women may receive tamoxifen or an aromatase inhibitor (AI) or those drugs in sequence as determined by the treating oncologist. Hormone therapy will be given for at least 5 years.

Biopsy

Procedure

Two tumor biopsies will be performed. The first tumor biopsy will be performed before apheresis for diagnostic purposes, and again after completion of the first four chemotherapy treatments. Patients will undergo local anesthesia with lidocaine and 1% epinephrine followed by 1-2 core biopsies of the breast primary and/or palpable axillary node with a 14 gauge, 16 cm. Bard needle or other similar needle. The procedure may be done under ultrasound guidance. If a metal clip or marker has not been previously placed in the tumor, it will be placed before treatment.

conventional surgery

Procedure

Definitive breast surgery Surgery will occur two to four weeks after the last course of chemotherapy. Modified radical mastectomy or lumpectomy and standard axillary dissection could be performed and the specific procedure will be decided by the patient and physician team. If a sentinel node dissection was done prior to chemotherapy and was negative, no further node dissection is necessary. A standard node dissection will be necessary if no node assessment was done prior to chemotherapy or if the pre- chemotherapy sentinel node was positive.

neoadjuvant therapy

Procedure

Chemotherapy: Paclitaxel (T) 175 mg/m2 intravenously (IV) over at least 3 hours day 1. Repeat every 2 weeks for 4 cycles. IT DCs will be injected into the primary breast mass or palpable axillary node, one week after the first, second and third T treatments.

radiation therapy

Radiation

Radiation therapy Radiation is started two to four weeks after surgery for all patients receiving lumpectomy and those patients after mastectomy that the physician feels chest wall radiation is warranted (example: T3 or T4 breast lesion, four or more axillary nodes etc.). The exact doses and methods of administration will be determined by the treating radiation therapist, but should be standard breast radiotherapy and not partial breast or investigational methods.
