Filter by:This trial is a multicenter, open-label, phase II trial conducted at 23 centers in China. High-risk HER2 positive patients receive pyrotinib 400mg/day for one year or half year for extented adjuvant therapy.
This will be a Phase 2 clinical trial to assess somatostatin receptor (SSTR) expression in Stage IV estrogen receptor positive (ER+) breast cancer using Gallium-68 DOTATATE or Copper-64 DOTATATE PET/CT.
This Phase III Trial will determine whether adjuvant chemotherapy (ACT) added to ovarian function suppression (OFS) plus endocrine therapy (ET) is superior to OFS plus ET in improving invasive breast cancer-free survival (IBCFS) among premenopausal, early- stage breast cancer (EBC) patients with estrogen receptor (ER)-positive, HER2-negative tumors and 21-gene recurrence score (RS) between 16-25 (for pN0 patients) and 0-25 (for pN1 patients).
The optical body surface image (C-RAD) was used to guide and track the change of positions, and multimodal images (including 2D X-ray images, CT images and PET-CT images) were used to verify the treatment positions. In order to explore the accuracy of breast cancer patients' treatment positions and its impact on dose of the new fixation device in two different fixed positions of arm up and arm down, optimize the position fixed equipment and methods of particle radiotherapy for breast cancer, and then establish the precision process of particle radiotherapy for breast cancer under the guidance of multimodal images. In a word, this is a dosimetry and prospective Phase II randomized clinical study of the accuracy of multi-modal guided particle radiotherapy for postoperative breast cancer with different arm position.
PEAK is a prospective, multicenter, non-interventional investigator-initiated trial (IIT) that aims to investigate the influence of the menstrual cycle phase on Ki67 in patients who either receive Tamoxifen, Aromatase inhibitors ± gonadotropin-releasing hormone (GnRH)-Analogues or nothing or no preoperative endocrine treatment as part of the clinical routine. The investigators moreover address the question whether PAM50 assessment in addition to Ki67 dynamics still impacts treatment recommendations.
Background: Creatine supplementation is an effective ergogenic nutrient for athletes, as well as people for people starting a health or fitness program. Resistance training previously been identified as an important method of increasing muscle mass and strength among people, specially in people with cancer to avoid sarcopenia. The potential of creatine supplementation for adaptations produced by strength training in cancer patients are still unknown. Objective: the primary aim of this study is to evaluate the effectiveness of a 16-week supervised resistance training program intervention with and without creatine supplementation in patients with breast cancer. Methods: A multicentre, randomized, double-blind, placebo-controlled study designed to evaluate the effects of creatine supplementation in addition to resistance training in breast cancer patients. Patients will be randomly assigned to 3 groups: a control group (CG) and two experimental groups. The first resistance training group (RG) will perform resistance training, while the second resistance-creatine experimental group (RCG) will perform the same resistance training as the RG and will also receive a 5 g/day supplementation of creatine for the duration of the exercise the 16-week intervention. RG participants will follow the same daily dosing protocol, but in their case, with dextrose/maltodextrin. Resistance training will be a 16-week supervised workout that will consist of a series of resistance exercises (leg press, knee extension, knee bends, chest press, sit-ups, back extensions, pull-ups, and shoulder press) that involved the largest muscle groups of the body and will be performed three times a week on non-consecutive days. Both the RG and the RCG will receive a supplement of soluble protein powder (20-30 g) daily. Discussion: The results of this intervention will help to better understand the potential of non-pharmacological treatment for improving strength and wellbeing values in breast cancer patients with and without creatine supplementation.
This research study is a prospective, single arm, pilot study, designed to evaluate the correlation between the immune and clinical responses of subjects with untreated Stage II-III triple negative breast cancer (TNBC) undergoing standard of care neoadjuvant chemo- immunotherapy.
Breast cancer is the most frequent cancer in women worldwide. Its incidence is increasing but mortality has decreased in a considerable way due to the combined effect of early detection and improvement in treatment . Irisin is encoded by the FNDC5 gene, whose expression is controlled by the peroxi- some proliferator activated receptor gamma coactivator 1 alpha (PGC-1α). PGC-1α is a transcriptional co-activator which does not bind directly to DNA. Studies indicated that the estrogen-related receptor alpha (ERRα) could be a factor that plays a role in PGC-1α binding to DNA. ERRα is encoded by the ESRRA gene and is an orphan nuclear receptor, which has two domains. One of them allows the interaction with DNA, and the second one with a ligand. The ERRα structure is similar to that of the estrogen receptor alpha (ERα), but this receptor does not bind to natural estrogens. ERRα interacts with a canonical sequence of the estrogen response elements (ERRE). ERRα and ERα could compete with each other to bind to similar DNA elements. Together, ERRα binds to DNA, in complex with PGC-1α, to regulate the activity of genes such as FNDC5 . CA15-3, a high molecular weight glycoprotein (300-450 kDa), is produced by the epithelial ducts and acinic breast cells and is then secreted in milk normally. It has been widely used for the prediction of bone metastases in patients with breast cancer .
Approximately 55,000 cases of breast cancer are diagnosed in Italy every year and the first-line therapy for carcinoma in situ, stage I, II and IIIA is surgical removal of the tumour. The incidence of chronic pain after breast cancer surgery is confirmed around 30%. This study aims to evaluate the impact of loco-regional anesthesia techniques in the context of multimodal analgesia in the prevention of chronic pain post-oncological breast surgery
To compare the efficacy and safety of capecitabine and cyclophosphamide (XC) versus physician's choice as maintenance therapy for patients with advanced breast cancer who achieved disease control after salvage treatment.
