简要总结
Primary Objectives:
- To prospectively evaluate the predictive accuracy of a previously discovered gene expression profile-based test to foretell pathologic complete response (pCR) to preoperative paclitaxel/FAC (5-fluorouracil, doxorubicin, cyclophosphamide) chemotherapy for stage I-III breast cancer.
- To evaluate if our genomic predictive test is specific to the paclitaxel/FAC regimen or it also predicts increased sensitivity to FAC only chemotherapy.
Secondary Objectives:
- To discover a molecular profile that is associated with pCR after FAC chemotherapy alone
- To establish a prospectively collected gene expression profile data bank of breast cancer for future studies
- To compare the pCR rates between patients who receive 6 courses FAC and those who receive sequential paclitaxel /FAC chemotherapies.
详细描述
The new test being studied measures the presence or absence of each of 12,000-15,000 human genes in the cancer using "DNA chip" technology. All of the therapeutic treatment that you will receive is part of the standard of care. Only the biopsy and Deoxyribonucleic acid (DNA) testing is investigational.
Before and during chemotherapy, you will need to have routine clinical and lab tests that are part of your standard of care. These tests may include x-rays such as computed tomography (CT) scan of the liver or lung, bone scan and mammograms, or ultra sonograms of the breast to find out the extent of the cancer at the time of diagnosis. Blood tests (1-2 tablespoon) will be performed before each FAC (5-fluorouracil, doxorubicin, cyclophosphamide) or FEC (5-fluorouracil, epirubicin, cyclophosphamide) chemotherapy end at least once every 2 weeks during weekly paclitaxel therapy to make sure that it is safe to receive further treatment. All of these tests are part of good clinical care and are not considered investigational.
During treatment with FAC or FEC chemotherapy, you will be seen by your physician every 3 weeks. During the weekly paclitaxel treatment you will be seen by your physician every 4-6 weeks. Additional visits may be necessary depending on your clinical course.
During this study, you will be asked to have a fine needle aspiration (FNA) of the cancer in your breast or lymph nodes. The FNA procedure involves insertion of a small needle into the tumor to suction out (aspirate) cells from the cancer 3-4 times in one session. A physician who is trained in this method will perform the procedure. It could be done at the same time when the diagnosis of your cancer is made or it may be done at later time point. The needle aspiration will have to be done before you start any chemotherapy for your cancer. A DNA chip test called transcriptional profiling will be performed on the FNA specimens at M. D. Anderson in Houston (TX, USA). The test will be done to try to predict if an individual is likely to have response to paclitaxel/FAC chemotherapy or not. This study is done to see how accurate this test is. The chemotherapy response prediction test was developed by investigators at Millennium Pharmaceuticals Inc. (Cambridge, MA, USA) and clinical scientists at M. D. Anderson. This research may lead to the development of a commercial diagnostic test.
Only patients who need chemotherapy to improve their chance of cure may participate in this study. Whether you would benefit from chemotherapy or not will be decided by your physician. During this study 18-24 weeks of chemotherapy will be given to you before surgery. It is clear from several large clinical studies that chemotherapy works equally well regardless of whether you receive it before or after breast surgery. By giving chemotherapy before surgery, researchers can study why some cancers respond so well to treatment. You may expect that 80-90% of the time the cancer will shrink and about 15-30% of the time the cancer will completely disappear from the breast or lymph nodes by the time you finish chemotherapy. Many of the patients who experience the complete disappearance of cancer will be cured. The purpose of this research is to find out who these individuals are and develop a test that could identify them at the time of the diagnosis. About 5-10% of patients do not experience any shrinkage of the cancer and may experience growth of the tumor. If the tumor grows during treatment, you will be switched over to another chemotherapy, you may receive radiation treatment, or you may have surgery. What is the best option for you will need to be decided by your treating physician.

Pathologic Complete Response Rate after completion of preoperative chemotherapy, based on routine clinical pathology report where Pathologic complete response defined as complete absence of any viable invasive cancer cells in resected breast and lymph nodes. Specimens in breast may contain in situ cancer (ductal or lobular carcinoma in situ) and still be considered complete response.
