Breast Cancer Clinical Trial
A Study of Gemcitabine, Epirubicin, and Paclitaxel Combination Chemotherapy Given Before Surgery to Patients With Locally Advanced Breast Cancer
Summary
The primary purpose of this study is to determine whether locally advanced breast cancer responds (by shrinking, by not progressing or by being destroyed) to combined chemotherapy (gemcitabine, epirubicin and paclitaxel) given before surgery to patients with locally advanced breast cancer. This study will also evaluate the toxicity of the chemotherapy combination to patients and will determine survival and progression-free survival 2 years after treatment. Also, the study will look at whether there are molecular and genetic changes in the tumor tissue that match the tumor's response to the chemotherapy.
Full Description
Primary chemotherapy has had an established role in locally advanced breast cancer. Studies have shown that the combination of chemotherapeutic agents is superior to single therapeutic agent in overall response rate and progression free survival. The inclusion of the most active drugs in combination regimens can improve the percentage of patients achieving a pathological complete response (pCR). The chemotherapy agents gemcitabine, epirubicin, and paclitaxel have been used individually to treat breast cancer. While use of the combination of these three drugs has been studied in the metastatic setting, the combination has not been evaluated in locally advanced disease. In this study the combination of the three agents gemcitabine, epirubicin, and paclitaxel [Taxol] will be administered to patients with locally advanced breast cancer prior to surgery; pathologic response will be determined at the time of surgery. The main objective of this study is to determine the pathological response rate for these patients. Also because prior studies have suggested that only a specific subset of tumors responds to a specific chemotherapeutic agent and that this subset is determined by the gene expression profile of each tumor, preoperative therapy protocols such as this provide an ideal setting to identify gene expression pattern and gene copy number changes that may predict response to a specific therapy using high-throughput assay methods and RNAlater. Therefore, this study will also look at the feasibility of tissue collection and analysis in identifying predictive markers of complete pathological response.
Eligibility Criteria
Inclusion criteria:
Females only
Consent for the collection of biopsy tissue in RNAlater solution
Biopsy specimens that were obtained by core biopsy or incisional biopsy and placed in RNAlater solution
Breast cancer that is:
unilateral
diagnosed histologically as invasive breast cancer without evidence of metastatic disease (except for stage IV with positive supraclavicular nodes only)
stage IIB, IIIA (T0-3N2), IIIB (T4N0-3 or T0-3N3), or IV (by involvement of positive supraclavicular nodes only). (Patients with clinical evidence of inflammatory breast cancer or superficial lesions must have a measurable mass in the breast or lymph nodes.)
measurable by physical exam, mammography, sonogram, CT scan, MRI, or x-ray
Evidence of adequate organ function (liver, bone marrow, kidney)
Ability to perform an adequate level of physical activity (Zubrod scale 0, 1, or 2)
Life expectancy of at least 10 years
Childbearing potential terminated by surgery, radiation, or menopause, or attenuated by use of an effective non-hormonal, barrier contraceptive method
Disease-free from prior nonbreast malignancies for at least 5 years before entry
Adequate cardiac function( measured by baseline LVEF on MUGA or echocardiogram greater than or equal to the institution's lower limit of normal)
Exclusion criteria:
Male
Hormonal birth control
The use of hormonal agents or raloxifene
Active infection
Pregnancy or breastfeeding
Bilateral malignancy or a mass in the opposite breast suspicious for malignancy, unless there is biopsy proof that the mass is not malignant
Previous therapy for breast cancer
Nonmalignant systemic disease that would keep the patient from being given the treatment or would prevent long-term follow-up
Active cardiac disease that would preclude the use of epirubicin and/or Taxol
Significant abnormal peripheral nerve disease (greater than or equal to Grade 2)
Any prior anthracycline or taxane-containing chemotherapy
Use of any investigational agent within one month before enrollment
Excisional biopsy of the breast
