Filter by:The purpose of this study is to provide access to palbociclib in Mexico and in selected Latin American countries before it becomes commercially available to patients with HR positive/HER2-negative ABC who are appropriate candidates for letrozole therapy.
A correlation between early changes in the tumor maximum standardized uptake value (SUVmax) on FDG-PET after one or two cycles of neoadjuvant chemotherapy (NAC) and the pathological response after 6 to 8 cycles has been demonstrated in several independent small series of patients. Breast tumor proliferation status has previously been demonstrated to be a good predictive factor of response to chemotherapy. The best method for assessing proliferation status is unclear. Proportion of cells staining for nuclear Ki67 antigen is the most widely used assay for comparing the proliferation status between tumors. However major variations in analytical procedure and interpretation limited its clinical value. Taking into account the prognosis and predictive value of proliferation gene as a common "signature" in breast cancer transcriptome analysis, quantitative assessment of mRNA expression of genes involved in proliferation has been developed by the investigators team and others. The evaluation of these parameters is quantitative and reliable and can be standardized for a clinical use. The main objective of the investigators study is to early predict pathological response to anthracycline-based neoadjuvant chemotherapy (NAC) using a combination of parameters based on FDG-PET imaging performed at baseline and after 2 cycles, and molecular markers of proliferation measured on pre-treatment biopsy (Ki67 protein level by immunohistochemistry and Ki67 mRNA level and the mRNA (messenger RNA) expression of the most pertinent genes of the Genomic Grade Index (GGI) component by RT (reverse transcriptase) - qPCR).
As cancer mortality rates improve in Asia, there is an increasing focus on patient-reported outcomes and survivorship issues. In view of the numerous medication and psychosocial issues that are commonly faced by early-stage breast cancer survivors, it deems important to develop and conduct specific interventional programs to mitigate these problems. In the literature, it is well recognized that psychosocial interventions are effective to manage emotional distress and quality of life, with the evidence clearly clustered in studies on female patients with breast cancer. One meta-analysis suggested that psycho-oncologic interventions including individual psychotherapy, group psychotherapy, psychoeducation, relaxing training can produce positive effects on emotional distress, anxiety and depression, and health-related QOL. The investigators hypothesize that a significant reduction in anxiety, improvement of cognition and improvement of health-related quality of life among those who receive psycho-education, in comparison to those in the usual care. Hence, this randomized trial is designed to assess the effectiveness of a psycho-educational group (PEG) intervention on supportive care and survivorship issues, which include anxiety, depression, cognitive function, toxicities management of cancer- or treatment- related physical symptoms, and health-related quality of life in early-stage breast cancer patients.
The two main objectives of this prospective study are: - to identify those patients for whom pre-treatment FDG (Fluorodeoxyglucose) PET (positron emission tomography) CT-scan (Computed tomography scan) provides useful information for the treatment of breast cancer (ASAINT 1), - to improve FDG PET-CT-scan imaging criteria for assessing response to neoadjuvant therapy early, in M0-patients (ASAINT 2). The secondary objective is to better understand the interactions between the imaging parameters of FDG PET-CT-scan and biological and histological features of breast cancer . This is a non-interventional study. Two PET-CT-scans are performed, one before starting treatment, and the other after 2 cycles of neoadjuvant chemotherapy. The two PET-CT-scans are prescribed by oncologists from the center of breast diseases Unit at St. Louis hospital, in Paris, France. Oncologists provide clear information to the patients on the purpose of the examination. The examinations are performed in the nuclear medicine department at St. Louis hospital. PET-CT-scans data, tumor characteristics, results of other imaging and biological tests, results of surgery and patient's follow-up are summarized in a "de-identified" file. This file has been declared to the National Commission on Informatics and Liberties (CNIL). The data in this file are established prospectively and secondary analyzed to assess the precise role of PET-CT-scans in the initial staging of breast cancer and to determine the optimal PET-CT-scans criteria to evaluate response to neoadjuvant treatment early.
This dose finding/extension study was designed originally to consist of three parts: Part A was intended to identify the MTD of the AZD2014/ palbociclib combination on a background of fulvestrant (referred to as the triplet) in postmenopausal women with locally advanced/ metastatic estrogen receptor positive (ER+) breast cancer. Part B was to further characterize safety, tolerability, PK, and preliminary efficacy in single-arm dose expansion groups. Part C was to be a Phase 2, randomized, double-blind, extension comparing the triplet and doublet combinations. Part C was deleted from the protocol and was not performed.
This pilot study concentrates on studying the trajectory of breast cancer patient's fear of recurrence (FoR) over the course of radiation therapy. The aim is to collect repeated ratings of 100 breast cancer patient's FoR over the course of their treatment. It is hypothesized that cancer patient's FoR level will rise on nearing the termination of the in radiotherapy treatment, and radiotherapist-patient interaction modifies the development of patient's FoR.
This is a Phase I study to assess the safety and Maximum tolerated dose (MTD) of paclitaxel + ribociclib (LEE011) in patients with Rb+, advanced breast cancer. Dose escalation will be performed using standard 3 + 3 dosing strategy. The starting dose of ribociclib (LEE011) is 200 mg once daily; dose escalation proceeds in 200 mg increments up to a maximum of 600 mg. Dose-limiting toxicities (DLT) will be based upon first-cycle toxicity.
The goal of this phase 2 study trial is to evaluate the utility of the radiolabel 18F-FSPG used before and after treatment to diagnose, predict, and evaluate response to therapy in patients with a wide variety of metastatic cancers.
This phase IIb trial studies how well alternative dosing of exemestane before surgery works in treating in postmenopausal patients with stage 0-II estrogen positive breast cancer. Chemoprevention is the use of drugs to keep breast cancer from forming or coming back. The use of exemestane may treat early stage (stage 0-II) breast cancer. Comparing the exemestane standard dose regimen versus two alternative, less frequent dose regimens may decrease undesirable symptoms and have similar efficacy in reducing serum estradiol.
The purpose of this research study is to determine how well pertuzumab and trastuzumab works in treating breast cancer that has spread to the brain. Pertuzumab and trastuzumab are treatments that stop breast cancer cells from growing abnormally by inhibiting (or blocking) members of a family of proteins that include Human Epidermal Growth Factor Receptor 2 (HER2). Pertuzumab and trastuzumab have been found to be very effective for HER2-positive breast cancer and are FDA approved for treatment of metastatic breast cancer outside of the brain when given through the vein. This suggests that pertuzumab and trastuzumab may help shrink or stabilize HER2-positive breast cancer that has spread to the brain in this research study. In this research study, the investigators are looking to see whether pertuzumab and trastuzumab will work to decrease the size of or stabilize breast cancer that has spread to the brain.
