Filter by:The purpose of this survey is to describe long-term tolerance as seen under current conditions of use for anastrozole.
The purpose of this study is to find out what effect the postoperative combination of therapies: trastuzumab (herceptin) and paclitaxel (taxol) will have on breast cancer recurrence. A combination of trastuzuamb and chemotherapy has been used in women with node positive and high risk node negative disease. This tests utilizes a well tolerated regimen of weekly paclitaxel and trastuzumab in women with T1, node negative tumors that are HER2 positive. We would like to determine how effective this drug combination is when used in women with early stage breast cancer, as well as to better define the side effects of this treatment.
This neoadjuvant chemotherapy protocol focusing on "triple-negative" breast cancers alone will gather a foundation of primary tumor and axillary lymph nodal response to primary chemotherapy and ongoing correlated disease-free (DFS) and overall survival (OS) outcome data. This comparative data can then be used in building subsequent trials.
RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking use of estrogen by the tumor cells. Anastrozole, letrozole, and exemestane may fight breast cancer by lowering the amount of estrogen the body makes. It is not yet known whether giving tamoxifen followed by anastrozole, letrozole, or exemestane is more effective than giving anastrozole, letrozole, or exemestane alone in treating breast cancer. PURPOSE: This randomized phase III trial is studying giving tamoxifen followed by either anastrozole, letrozole, or exemestane to see how well it works compared to anastrozole, letrozole, or exemestane alone in treating postmenopausal women with hormone-responsive invasive breast cancer that has been completely removed by surgery.
Optimal management of patients with locally advanced breast cancer remains a complex therapeutic problem. Newly diagnosed breast cancers in the United States with a higher incidence in medically underserved areas. The optimal intensity and duration of neoadjuvant chemotherapy still remains controversial due to the difficulty of evaluating response to therapy. The goal would be to prevent over and under treatment of patients with neoadjuvant chemotherapy.
Some chemotherapies, including docetaxel, are better tolerated and just as effective when giving the dose weekly rather than on an every three week basis. The purpose of this study is to compare 2 schedules of combination chemotherapy with docetaxel for the effects on quality of life. Standard every three week chemotherapy will be compared with weekly chemotherapy for metastatic or locally advanced breast cancer.
The purpose of this clinical trial was to determine whether combining iniparib (BSI-201) with standard chemotherapy in estrogen receptor (ER)-negative, progesterone receptor (PR)-negative, and human epidermal growth factor receptor 2 (HER2) negative metastatic breast cancer patients improve clinical benefit compared to treatment with standard chemotherapy alone. Based on data generated by BiPar/Sanofi, it was concluded that iniparib does not possess characteristics typical of the poly (ADP-ribose) polymerase (PARP) inhibitor class. The exact mechanism has not yet been fully elucidated, however based on experiments on tumor cells performed in the laboratory, iniparib is a novel investigational anti-cancer agent that induces gamma-H2AX (a marker of DNA damage) in tumor cell lines, induces cell cycle arrest in the G2/M phase in tumor cell lines, and potentiates the cell cycle effects of DNA damaging modalities in tumor cell lines. Investigations into potential targets of iniparib and its metabolites are ongoing.
Rationale: Approximately 25% of breast cancers detected are non palpable. Accordingly, a localization technique is required to help the surgeon to find and remove the cancer. The current technique (wire guided localization [WGL]) is difficult to perform and has a high rate of tumour positive margins in the resected specimen, requiring a second operation. A new approach in the localization and resection of non-palpable malignant breast lesions is 'radio guided occult lesion localization' (ROLL). ROLL was introduced as a possible replacement for WGL at the `European Institute of Oncology' in Milan in 1996. This technique utilizes the intratumourally injected radiotracer, that is generally used for the lymphatic mapping and SNB, to localize the primary tumour guided by the gamma probe. Five studies so far have proven the applicability of this method. Objective: To evaluate the efficacy of Radio Occult Lesion Localisation (ROLL) versus Wire guided Localisation (WGL) in breast conserving surgery for non-palpable breast cancer Study design: A multicenter, prospective randomized clinical trial. Patients with proven non-palpable breast cancer will be randomized for either ROLL or WGL. Study population: 316 women with a core biopsy proven non palpable cT1 breast carcinoma that are eligible for a breast conserving treatment and sentinel node biopsy (SNB). Intervention (if applicable): Patients in the WGL group will undergo intra tumoural injection of a nuclear radiotracer under stereotactic or ultrasonographic guidance. After scintigraphic imaging, to monitor the migration of the radiotracer, a guide wire will be inserted under stereotactic or ultrasonographic guidance. The excision of the primary tumour is guided by the inserted wire and the sentinel node procedure is performed using a gamma probe and intratumoural injection of patent blue. Patients in the ROLL group will undergo the same procedure except for the guide wire insertion. The excision of the primary tumour is guided by the gamma probe. Main study parameters/endpoints: Primary study endpoints; ROLL vs WGL: 1. The percentage of tumour-free margins (invasive and in situ) 2. The volume and maximum diameter of the lumpectomy Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There is no pre-, per- or post operative extra burden. The radiofarmacon is already used in the standard care of breast cancer patients for the sentinel node biopsy. The used radio-active substance does not damage the patient. A specific burden questionnaire, aimed at evaluating the burden of the cosmetic result, will be administered. To further assess the net impact in terms of Health Related Quality of Life (HRQoL) also the EQ5D will be obtained at T = 0, 6, 12 and 26 weeks after the initial diagnostic work-up. Should the results indicate that overall the WGL procedure lead to better clinical outcome a cost-effectiveness analysis is foreseen using bootstrapping to assess the uncertainty with regard to the balance between costs and effects. All analyses will be limited to a half year time horizon. Accordingly, discounting of costs or effects is not applicable.
The primary objective is to compare ARIMIDEX (anastrozole) 1 mg once daily with Tamoxifen 20 mg once daily as adjuvant treatment in terms of: incidence of fatty liver diseases. The second objectives are to compare ARIMIDEX (anastrozole) 1 mg once daily with Tamoxifen 20 mg once daily as adjuvant treatment in terms of: incidences of abnormal liver function test, and time to treatment failure.
This trial provides a unique opportunity in that it combines genomic, proteomic and pharmacogenomic assessments in patients receiving chemotherapy for advanced breast cancer. To date no other trials have analyzed gene and protein expression at the same time points in the same patient, combined with clinical outcome. Similar to previous attempts to predict response based on expression of a single gene or protein, we expect that neither genomic or proteomic profiling alone will be sufficient to optimize therapy. Rather, we expect an iterative process that combines information gleaned from both platforms, modified to avoid toxicity based on pharmacogenomics.
