NCT02301988
This is a randomized, double-blind, placebo-controlled, multicenter, pre-operative Phase II study designed to estimate the efficacy of ipatasertib combined with paclitaxel chemotherapy versus placebo combined with paclitaxel chemotherapy in women with Stage Ia - IIIa triple-negative breast adenocarcinoma. The anticipated time on study treatment is 12 weeks.
NCT01385280
RATIONALE: Estrogen can cause the growth of tumor cells. Hormone therapy using therapeutic estradiol may fight breast cancer by lowering the amount of estrogen the body makes. Though estradiol initially produces stimulation of ER+ cancer cells, both laboratory and some clinical experience indicate that it may have the opposite effect on such cells, once they have become resistant to estrogen deprivation. In laboratory models, there is death of the "resistant" population after estradiol treatment, followed by restoration of sensitivity of the remaining cells to estrogen deprivation, as with an aromatase inhibitor. Exemestane may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving therapeutic estradiol together with exemestane may kill more tumor cells. PURPOSE: This clinical trial studies therapeutic estradiol and exemestane in treating post-menopausal patients with hormone receptor-positive metastatic breast cancer
NCT02297230
Paclitaxel 30 mg/m2 twice/week Trastuzumab 4mg/kg, loading dose, then 2 mg/kg weekly and Concurrent RT (to start within one week from first dose of Paclitaxel/Trastuzumab) to breast, supraclavicular, axillary fields, 45 Gy @ 1.8 Gy/fraction, + 14 Gy @ 2 Gy/fraction to the primary tumor. At the end of chemo-radiation, Trastuzumab will be continued weekly until surgery and as per standard of care after surgery for up to 1 year total. \*\*Surgery: Patients will undergo lumpectomy and axillary node dissection or modified radical mastectomy within two months following discontinuation of pre-operative systemic therapy, contingent upon recovery of skin toxicity. Pathologic response will be evaluated at the time of surgery. Additional tissue samples will be collected from the surgical specimen for assessment of tumor molecular characteristics. \*\*\*All patients may undergo four cycles of post-operative Standard AC (doxorubicin 60 mg/m2, cyclophosphamide 600 mg/m2) or four cycles of post-operative epirubicin and Cyclophosphamide (epirubicin 100 mg/m2, cyclophosphamide 600 mg/m2) if doxorubicin is not available Tamoxifen as well or any alternative antihormonal therapy may be prescribed for five years for patients with hormone receptor positive tumors. Herceptin (Trastuzumab) will be prescribed for a total of 1 year since first dose as per standard of care.
NCT00651976
RATIONALE: Hormone therapy using letrozole may fight breast cancer by lowering the amount of estrogen the body makes. Giving letrozole before surgery allows us to monitor the effects of letrozole on the tumor on a molecular level and determine markers of response to treatment. PURPOSE: This study will show us how well letrozole works in treating postmenopausal women with stage I, II or III breast cancer that can be removed by surgery.
NCT03089502
Breast cancer is the leading cause of cancer among Canadian women with nearly 26,000 new cases diagnosed each year. Fortunately, advancements in diagnostic tools and curative treatments have significantly improved overall survival. However, the development of cardiac toxicity (including asymptomatic and symptomatic heart failure) associated with use of anthracycline containing chemotherapy and targeted therapies including trastuzumab limits improvements in survival for women with breast cancer. Cardiac toxicity is a life threatening complication that leads to reduced physical functioning and quality of life. The increased risk is associated with shared risk factors among cancer and heart failure and the direct influence of cancer therapy on the cardiovascular system. Cardiac rehabilitation (CR) (including exercise training and education/counselling) has been shown to improve health outcomes, reduce heart failure related hospitalizations and modestly improve mortality among individuals with non-treatment related heart failure and may benefit women with breast cancer and treatment related cardiac toxicity (BC-CT). Therefore, this single centre, randomized control trial aims to determine if participation in an exercise based CR program can improve cardiorespiratory fitness, cardiovascular function/structure and health, and quality of life among women with BC-CT.
NCT00793962
The purpose of this study is to compare the efficacy and toxicities of hypofractionation radiotherapy with conventional fractionation radiotherapy in breast cancer patients treated with mastectomy.It is hypothesized that the efficacy and toxicities are similar between the two groups.
NCT02310711
The proposed study is a single-center, prospective, pilot, observation study to tabulate and measure the changes that occur during treatment and healing for breast conserving therapy (BCT) in women with non-metastatic breast cancer for comparison to the multiscale model of breast lumpectomy and healing in order to identify targets for improving BCT. The study will be comprised of 12 de novo breast cancer patients with non-metastatic breast cancer undergoing BCT. Subjects will be enrolled in the study during the 3 weeks prior to receiving their BCT surgery and will be followed for six months after the BCT surgery. A total of 6 visits (not including the surgery) are planned.
NCT00743314
RATIONALE: Diagnostic procedures, such as single-photon emission computed tomography and computed tomography lymphoscintigraphy, may help lower the dose of radiation therapy after surgery, and help prevent lymphedema. PURPOSE: This clinical trial is studying single-photon emission computed tomography and computed tomography lymphoscintigraphy followed by intensity-modulated radiation therapy to see how well they work in treating patients who have undergone surgery for stage I or stage II breast cancer.
NCT01927081
The purpose of this research study is to evaluate whether self-management discussion groups are helpful for women with advanced breast cancer who are experiencing pain. The study is looking at the usefulness of two different types of discussion groups, one of which also includes gentle exercise.
NCT01632332
The purpose of this study is to look at the safety and immune response to a vaccine used in patients previously treated for HER2 (human epidermal growth factor receptor 2) positive breast cancer.
NCT03696004
Systemic chemotherapy along with radiotherapy has been successfully used to post-operatively manage patients following tumour resection in breast cancer. This was further supported with clinical trials conducted in the 1970s and 1980s which shows significant improvement in progression-free of tumours and overall survival rates in patients who undergo chemotherapy for operable breast cancer.(1)-(2) Neoadjuvant chemotherapy on the other hand, involves the administration of the chemotherapeutic agents some weeks before appropriate breast surgery. This induces reduction in the tumour size and allows for breast conservative surgery instead of mastectomy in some cases. Techniques for tumour localization in neoadjuvant chemotherapy using metallic markers allowing lower excision of breast tissue without compromising margins and breast conservation being feasible in many patients have evolved over time.(3)-(7)-(9) However, there are recent concerns questioning the increase use of neoadjuvant chemotherapy in breast cancer it as it may not be beneficial to patients in the long run.(10)
NCT02189278
Evidence-based guidelines recommend cancer surveillance procedures for breast cancer survivors including physical examination, mammography, breast self-exam, and gynecologic follow-up. The early detection of recurrent and new cancers can best be achieved through the combined, on schedule use of these surveillance procedures. Yet, data suggest that up to 55% of breast cancer survivors do not undergo these procedures as recommended. This study tests a telephone-based psychosocial intervention aimed at improving adherence to recommended surveillance in breast cancer survivors. The psychosocial intervention for improving adherence is compared to treatment as usual.
NCT03648983
This randomized pilot clinical trial studies arm circumference measurement with or without bioimpedance spectroscopy in finding extra lymph node fluid build up in the arm (lymphedema) early in patients with stage I-III breast cancer undergoing lymph node dissection or sentinel node biopsy. Diagnostic procedures, such as bioimpedance spectroscopy, may allow doctors to find and diagnose lymphedema earlier than arm circumference measurement alone.
NCT02599506
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.
NCT03676114
Breast cancer patients often have perioperative emotional disorders such as anxiety and depression, which can lead to poor quality of recovery.This study aims to determine whether ketamine could improve the quality of recovery in breast cancer patients. Meanwhile, it will show if ketamine could improve anxiety, depression, postoperative pain and fatigue.This trial also will bring great concerns on patients' mental health perioperatively and explore the measures to improve their quality of life.
NCT01332630
The goal of the first part of this clinical research study is to find the highest tolerable dose of TPI-287 in patients with breast cancer that has spread to the brain. The goal of the second part of this study is to learn if TPI-287 can control breast cancer that has spread to the brain. The safety of this drug will also be studied.
NCT00053898
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Tamoxifen may fight breast cancer by blocking the use of estrogen. Anastrozole may fight breast cancer by decreasing estrogen production. It is not yet known whether anastrozole is more effective than tamoxifen in preventing the recurrence of breast cancer. PURPOSE: This randomized phase III trial is studying anastrozole to see how well it works compared to tamoxifen in preventing the recurrence of breast cancer in postmenopausal women with ductal carcinoma in situ who are undergoing lumpectomy and radiation therapy.
NCT00193726
One of the basic principles of cancer chemotherapy is that these drugs act exclusively or mainly on cells in cycle. Estrogens have been shown to increase the fraction of breast cancer cells in cycle. Tamoxifen on the other hand, decreases the proliferative fraction and has been shown to negatively impact on the results of adjuvant chemotherapy in breast cancer when given concomitantly. A number of previous studies have attempted estrogenic recruitment of cancer cells (into cell cycle) to increase the efficacy of chemotherapy in locally advanced and metastatic breast cancer. Although some studies showed an increase in response rates in the recruitment arm, there was no benefit in time to progression or survival in any of the studies. These results may have been due to the inadequate sample size of the studies and advanced stage disease (with presumably higher fraction of inherently chemoresistant cells). The present study is designed to test the hypothesis that estrogenic recruitment of micrometastatic disease in operable breast cancer will increase the efficacy of standard adjuvant chemotherapy after surgery. The intervention arm of the study will involve administration of short duration estrogen prior to each cycle of adjuvant chemotherapy. The end-points are disease free and overall survival.
NCT02802748
VENTANA is a "window-of-opportunity" trial that will explore whether, similar to CDK4/6 inhibitors, Oral Metronomic Vinorelbine in combination with Letrozole induces a superior anti-proliferative effect than Letrozole alone.
NCT01973660
Non-randomized, open label, multicentric translational research study in women with untreated invasive breast carcinoma eligible for primary surgery (Stage I-IIIA). The aim of PAMELA is to test the hypothesis that PAM50 HER2-enriched (HER2-E) subtype better predicts response to neoadjuvant dual anti-HER2 blockade, with or without endocrine therapy, compared to traditional clinical HER2 classification. Furthermore, we posit that characterization of gene expression patterns may identify profiles of those who may be safely spared chemotherapy.
