Filter by:Background and Aim: Breast carcinoma is the most common type of cancer and the most common cause of cancer-related mortality among women worldwide. Cancer stem cells (CSCs) are thought to be responsible for tumor initiation, progression, dissemination and resistance to chemotherapy and radiotherapy. CD133 is a trans-membrane glycoprotein which is considered as a putative CSCs marker. It has been extensively used as a stem cell marker for normal and cancerous tissues. Emerging evidence suggests that CD133 may be a critical factor in tumor development, progression and metastasis. The aim of this study was to evaluate expression status of CD133 in invasive ductal carcinoma (IDC) of the breast and its role during breast cancer progression and to correlate its expression with some known clinicopathological parameters.
This is a Phase II, single-center, double-blind, placebo-controlled, randomized study of Pyrotinib in combination with Doxorubicin/Epirubicin and Cyclophosphamide followed by Docetaxel/nab-Paclitaxel as neoadjuvant therapy for women with hormone receptor positive HER2-negative stage II to III breast cancer. Patients randomized to the study arm/control arm will receive standard neoadjuvant chemotherapy in combination with pyrotinib/placebo, respectively. The primary endpoint of the study is the total pathological complete response (pCR) rate. Secondary endpoints include the pCR rate in breast only, objective response rate(ORR), event-free survival, overall survival, and toxicity. We will also explore potential prognostic and predictive biomarkers.
This clinical trial examines a new imaging technology, contrast-enhanced mammography, in predicting breast cancer. Contrast-enhanced mammography is similar to standard mammography, but it includes an intravenous (by vein) injection of iodine-based contrast, which makes tissue and blood vessels more visible in scans. Contrast-enhanced mammography may work better in detecting cancer in the breast that is not seen on other imaging tests and may help doctors find the most suspicious areas of the breast to biopsy, which could increase the chances of finding breast cancer.
Insomnia affects about 60% of the patients treated with radio-chemotherapy, a percentage twice higher compared to that observed in the general population. This sleep disorder increases cancer-related fatigue (CRF), the side effect most often reported by patients. Conversely, it is well accepted that adapted physical activity (APA) improves tolerance to treatment, decreases the risk of recurrence, increases survival, and reduces CRF. The present study aims to evaluate, in non-metastatic breast cancer patients, the composition and architecture of sleep by ambulatory polysomnography and to verify the effects of an APA rehabilitation program (3 times a week during 12 weeks), on the quality and quantity of sleep, daytime sleepiness. The biological markers: melatonin and body temperature will be studied to better understand the chronobiological mechanisms of the sleep-wake rhythm. Finally, the physiological responses to exercise, pain, CRF and finally quality of life will be studied at the beginning, at the end of the program and at a distance from it. Improved sleep-wake rhythm by a physical activity may reduce CRF, prevent recurrence and comorbidities.
This proposed technique, called "Nonlinear Elasticity Mapping (NEM)", is an innovative approach to estimate (i.e., linear and nonlinear) elasticity to provide complementary and relevant information for identification and characterization of breast masses. The proposed technique includes imaging the (nonlinear) elasticity parameter in a quantitative manner and measuring two new and relevant parameters. These parameters, together with linear elasticity, are used to differentiate breast masses. The first parameter is the nonlinearity of the elasticity.
This phase II/III trial investigates the difference in rates of infusion hypersensitivity reaction in patients with breast cancer who are receiving paclitaxel alone or in combination with other cancer drugs which require parenteral rescue medication after stopping standard pre-medications (dexamethasone, diphenhydramine, famotidine/cimetidine/ranitidine), compared to continuing premedications. Paclitaxel is a drug used to treat breast cancer, ovarian cancer, and autoimmune deficiency syndrome (AIDS)-related Kaposi sarcoma. It blocks cell growth by stopping cell division and may kill cancer cells. It is a type of antimitotic agent. However, there are side-effects and toxicities associated with repeat exposure to this pre-medication regimen. With prolonged use of paclitaxel, especially during weekly regimens, patients are exposed to repeat doses of drugs that prevent hypersensitivity reactions. Side effects include, but are not limited to, insomnia, gastritis, fluid retention, weight gain, mood changes and immune suppression. The information gained from this study may positively influence clinical practice and help researchers develop methods to safely stop pre-medications.
Calcification clusters are 30-40% of recalls in mammographic screening, but have a low positive predictive value (~15%) for ductal cancer in situ (DCIS) or invasive cancer. These calcifications often need histological assessment with stereotaxic guided biopsy (Mammotome). With extended calcifications, choosing the best area to biopsy may be challenging. The main objective of this 1:1 randomized controlled clinical trial is to compare the accuracy of the CESM guide (study arm with biopsy under CESM guidance) with the traditional Mammotome (control arm with biopsy under stereotactic guidance) in conducting the biopsy in the area of greatest malignancy/grade of the lesion, using as gold-standard the histological exam of the operating piece. Women recalled with indication to perform stereotactic biopsy for clusters of suspicious calcifications on mammography (BIRADS R3 or R4 or R5) not mass-associated will be included. Anticipated sample size is 100 women per arm.
The purpose of this study is to find out how often the researchers can avoid an ALND in patients with early-stage, node-positive HR+/HER2- breast cancer who are having upfront surgery. The study researchers think that, if AUS before surgery can help identify people who may have up to 3 affected lymph nodes, it will be possible to perform the less radical standard SLNB during surgery.
Study of sexual health by repeated anonymous self-administered questionnaires in patients treated for non-metastatic breast cancer and referred to Jeanne de Flandre hospital for possible preservation of their fertility. Sexual health is affected by treatments and improves after the treatments. Sexual health is influenced by multiple factors : oncology treatments received, self-esteem, body image, anxiety, depression, professional activity
A assessment of the efficacy of first-/second-line endocrine therapies ± target therapies and chemotherapy in real-life of in patients with hormone receptor-positive (HR+)/HER2-negative metastatic breast cancer has not yet been conducted in Moscow. Methods: Observational, retrospective study carried out in oncology hospitals in Moscow, in patients with hormone receptor-positive (HR+)/HER2-negative metastatic breast cancer. The descriptive analysis will be conducted for patient characteristics, responses to treatment and treatment outcomes. This study will provide retrospective chart review of evidence on the use of therapy in routine clinical practice, with a focus in population of Moscow
